This document proposes a vision for a Self Guided Escape Velocity Shuttle (SGEVS) that could travel between astronomical bodies such as planets, stars, and galaxies. It outlines 5 phases for the project: 1) calculating escape velocity, 2) self-guiding after escape velocity is reached, 3) navigating to the destination, 4) self-healing and sustaining itself, and 5) making multiple jumps between locations. It then discusses approaches for calculating gravitational forces, mass, angular momentum, and escape velocity that could enable the SGEVS to navigate and propel itself through space. Renewable cryogenic fuels generated from materials in space are proposed to power the shuttle.
A paper which analyses the motion of a satellite launch vehicle, a rocket, from the moment it is launched till when it is placed into orbit. The paper contains derivations for equations for thrust, mass, mass loss, distance, velocity, burnout time and burnout velocity
So what launch speed does a satellite need in order to orbit the earth? ... The motion of satellites, like any projectile, is governed by Newton's laws of motion.
Satellites orbit Earth and other celestial bodies. They come in many types but generally have an antenna and power source. Satellites are launched into precise orbits using rocket boosters and follow orbital mechanics principles. Once in orbit, they perform tasks like Earth observation, communications, navigation, and scientific research. As technology advanced, satellite uses grew from early models like Sputnik to large constellations serving various purposes today.
Parallax is the apparent change in position of an object when viewed from different positions. It can be used to measure distances to celestial objects. Stellar parallax involves measuring the difference in the position of a nearby star observed from opposite sides of Earth's orbit around the Sun. This allows astronomers to determine the star's distance using trigonometry. In 1989, the Hipparcos satellite improved parallax measurements for over 100,000 nearby stars. The Gaia satellite, launched in 2013, can measure parallax angles to greater accuracy, mapping stars up to tens of thousands of light years away.
Satellites can be either natural or artificial. The moon is the natural satellite of Earth, while examples of artificial satellites include Sputnik, Aryabatta, and INSAT. Orbital velocity is the velocity at which a satellite revolves around a planet in a fixed orbit, and can be calculated using an expression involving the mass of the satellite, radius of its orbit, and gravitational force between the satellite and planet. The time period for a satellite to complete one orbit is also determined by an expression involving the radius of its orbit.
The document discusses the ESA's Gaia space telescope mission. Gaia will map the Milky Way galaxy by measuring the positions, distances, and motions of over 1 billion stars. It carries sophisticated digital cameras with nearly 1 billion pixels to obtain astrometry and photometry of stars, and will precisely measure the radial velocities of up to 100 million stars. The data it collects will provide insights into the composition, formation and evolution of our galaxy.
An artificial satellite is a man-made object sent into space to orbit Earth or another celestial body. Satellites serve various functions including telecommunications, military surveillance, weather monitoring, and exploring the universe. Key parts of a weather satellite include monitoring chambers, storage for collected data, antennas, instruments to measure greenhouse gases, solar panels, and cloud sensors. Satellites provide essential information for disaster response, such as evacuation planning, and capturing images of natural disasters like flooding and fires.

There are two types of satellites: natural and artificial. Natural satellites like the Moon orbit planets, while artificial satellites are human-made objects placed into orbit, like Sputnik 1. There are different types of artificial satellites depending on their orbit, such as geostationary satellites that orbit over the equator at a fixed position, and polar satellites that orbit from pole to pole.

A space probe is an uncrewed spacecraft that is used to make observations in deep space and send information back to Earth. Unlike satellites that orbit Earth, space probes have enough energy to escape Earth's gravity and travel among planets. Radio commands and onboard computers guide space probes and make corrections to their trajectories. Key components of space probes include sensors to study environments, communication systems to send data to Earth, thermal controls to regulate temperature, and power supplies. Space probes provide valuable data about other objects in our solar system.
Orbit design for exoplanet discovery spacecraft dr dora musielak 1 april 2019Dora Musielak, Ph.D.
Most exoplanets have been discovered with space telescopes. Starting with an overview of rocket propulsion, this presentation introduces spacecraft trajectories in the Sun-Earth-Moon System, focusing especially on those appropriate for exoplanet detection spacecraft. It reviews past, present, and future exoplanet discovery missions.
1) The document discusses concepts related to achieving and maintaining orbit around Earth such as escape velocity, elliptical orbits with apogee and perigee, and how speed and timing can adjust orbits.
2) It also describes different types of unmanned satellites that orbit Earth including communication, weather, and navigational satellites as well as their purposes and orbit types like geostationary and polar orbits.
3) Satellites have provided many benefits for exploring space and applications on Earth such as television, phone calls, storm tracking, mapping, and rescue beacon detection.
The Broseidon Orbiter mission will launch on September 27, 2014 from Cape Canaveral, Florida to conduct a two-year orbital mission around Mars beginning June 13, 2015. The mission aims to landscape terrain for potential human settlement and study Martian climate and weather conditions. Using a Hohmann transfer orbit, the spacecraft will depart Earth with a hyperbolic trajectory, cruise in an elliptical orbit around the sun, and arrive at Mars with another hyperbolic trajectory to enter a 250km circular orbit. Calculations determine propellant needs, launch parameters, and optimal transfer trajectory between Earth and Mars to complete the seven-month interplanetary journey.
This document analyzes trajectories to reach the heliopause and exit the solar system using nuclear thermal propulsion (NTP) and Oberth maneuvers. It finds that NTP, which can provide much higher specific impulse than chemical propulsion, enables significantly faster trajectories when combined with Oberth maneuvers where the spacecraft fires its engines near the closest approach to the Sun. The document models trajectories from various launch vehicles that take the spacecraft close to the Sun, where it executes a large velocity change to enter an hyperbolic orbit leaving the solar system. It finds that lower perihelion distances and higher Oberth burns result in higher exit velocities from the solar system.
The SPOT satellite is designed to transmit solar power from orbit around Mars to ground stations on Mars to power rovers. It will use a Hohmann transfer orbit to reach Mars, where 98 square meters of solar panels and radioisotope thermoelectric generators will wirelessly transmit power through a high gain antenna. Additionally, five cameras will provide constant imagery of Mars to astronauts. The satellite will achieve a "geostationary-like" orbit 17,000 km above Mars to maintain constant communication with ground stations as it transmits power and images.
Simulation of Deployment and Operation of an Earth Observing SatelliteAlber Douglawi
1) A simulation was conducted of a spacecraft deploying from a launch vehicle and performing attitude control to point its sensor at targets on Earth. Initially, the spacecraft tumbled out of the launch vehicle and thrusters were used to detumble it and align with the local horizontal frame.
2) During operations, a targeting algorithm prioritized 1000 targets and reaction wheels oriented the spacecraft to point at the highest value targets within its sensor range every 100 seconds. Over one day, this allowed it to image 235 targets worth a total of $67461.
3) Disturbance torques from the gravity gradient, solar radiation pressure, aerodynamics, and flexing of deployed solar panels and sensor were modeled. Gains

Upon reaching Mars, the orbiter entered orbit through phases like engine firing and communication blackout before resuming contact with Earth. Factors like thermal environment and reduced solar power at Mars' orbit were also considered.

Ultrafast transfer of low-mass payloads to Mars and beyond using aerographite...Sérgio Sacani
With interstellar mission concepts now being under study by various space agencies and institutions,
a feasible and worthy interstellar precursor mission concept will be key to the success of the long
shot. Here we investigate interstellar-bound trajectories of solar sails made of the ultra lightweight
material aerographite. Due to its extremely low density (0.18 kgm−3) and high absorptivity (∼1), a
thin shell can pick up an enormous acceleration from the solar irradiation. Payloads of up to 1 kg can
be transported rapidly throughout the solar system, e.g. to Mars and beyond. Our simulations consider
various launch scenarios from a polar orbit around Earth including directly outbound launches as well
as Sun diver launches towards the Sun with subsequent outward acceleration. We use the poliastro
Python library for astrodynamic calculations. For a spacecraft with a total mass of 1 kg (including
720 g aerographite) and a cross-sectional area of 104 m2, corresponding to a shell with a radius of 56m,
we calculate the positions, velocities, and accelerations based on the combination of gravitational and
radiation forces on the sail. We find that the direct outward transfer to Mars near opposition to Earth
results in a relative velocity of 65 kms−1 with a minimum required transfer time of 26 d. Using an
inward transfer with solar sail deployment at 0.6AU from the Sun, the sail’s velocity relative to Mars
is 118 kms−1 with a transfer time of 126 d, whereMars is required to be in one of the nodes of the two
orbital planes upon sail arrival. Transfer times and relative velocities can vary substantially depending
on the constellation between Earth andMars and the requirements on the injection trajectory to the Sun
diving orbit. The direct interstellar trajectory has a final velocity of 109 kms−1. Assuming a distance
to the heliopause of 120AU, the spacecraft reaches interstellar space after 5.3 yr. When using an
initial Sun dive to 0.6AU instead, the solar sail obtains an escape velocity of 148 kms−1 from the
solar system with a transfer time of 4.2 yr to the heliopause. Values may differ depending on the
rapidity of the Sun dive and the minimum distance to the Sun. The mission concepts presented in this
paper are extensions of the 0.5 kg tip mass and 196m2 design of the successful IKAROS mission to
Venus towards an interstellar solar sail mission. They allow fast flybys atMars and into the deep solar
system. For delivery (rather than fly-by) missions of a sub-kg payload the biggest obstacle remains in
the deceleration upon arrival.

Simulation of Interplanetary Trajectories Using Forward Euler Numerical Integ...Christopher Iliffe Sprague
The document discusses simulating interplanetary trajectories using forward Euler numerical integration. It summarizes the Ulysses mission, which utilized a gravity assist from Jupiter to achieve a solar polar orbit. The objectives are to validate Euler's method for modeling gravity-influenced motion and study how a spacecraft's velocity and position upon entering a body's sphere of influence affect its trajectory. MATLAB code is presented to model trajectories. Results show the spacecraft's velocity and anomaly change over its hyperbolic path, and that decreasing entry position or increasing entry velocity decrease trajectory deflection.
1) Spacecraft come in many types including manned spacecraft to carry astronauts, orbiter spacecraft that enter orbit around other planets or moons, atmospheric spacecraft that study planet atmospheres, lander spacecraft that touch down on surfaces, and observatory spacecraft that study targets from orbit.
2) Key spacecraft subsystems include power (solar cells and batteries), attitude and orbit control (propulsion and stabilization), telemetry for communication with Earth, antennas, and more.
3) Launch involves fitting spacecraft inside fairings, multi-stage rockets to achieve orbit and departure trajectories, and deployment of solar arrays and antennas after launch vehicle separation.
Chandrayaan-3 is India's third lunar mission to soft land on the lunar south pole region in order to conduct scientific experiments studying the lunar geology, atmosphere, and environment. The mission objectives are to demonstrate a safe soft landing on the lunar surface, conduct rover operations, and on-site surface experiments. Chandrayaan-3 was successfully launched on July 14, 2023 and is expected to land on the lunar surface between August 23-24, 2023. The mission advances India's space exploration capabilities and promotes international cooperation in space.
Orbits and space flight, types of orbitsShiva Uppu
This document discusses orbital mechanics including different types of orbits around Earth and other planets. It begins by defining orbital elements like eccentricity, semi-major axis, inclination, and orbital period. It then describes different types of orbits including low Earth orbit, geosynchronous orbit, polar orbit, and Hohmann transfer orbits. Basic orbital equations are provided relating centripetal force, gravitational force, orbital velocity, and orbital radius. Numerical examples are worked through to calculate orbital velocity, orbital radius, and orbital period for satellites orbiting Earth.
This document is a patent application for a method of delivering items in space using a hybrid propulsion system called the "remote fuel method". It combines aspects of beamed power propulsion, where energy is provided remotely, and standard rocketry, where physical fuels provide acceleration. The method allows fuels to be accelerated in small quantities from a remote source to rendezvous with payloads, preventing the exponential growth in fuel mass ratios seen with increasing delta-V requirements in standard rocketry. This allows for efficient generation of large delta-V values needed for missions outside of orbital resupply, such as exploration of the asteroid belt.

Immersive Learning That Works: Research Grounding and Paths ForwardLeonel Morgado
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
The binding of cosmological structures by massless topological defectsSérgio Sacani
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

1. World Space Week - Exploring New Worlds in Space a Reality:
SGEVS (Self Guided Escape Velocity Shuttle)
- Vision Article by R. Naga Vamshidhar.
“While in Dreams, I Float in Space”
Our cosmic Address:
India – Asia – Earth – Earth Moon System – Inner Solar System – Solar System – Solar Interstellar
Neighbourhood – Orion Cygnus Spiral Arm – Milky Way Galaxy – Local Galactic Group – Virgo Cluster – Virgo Super
Cluster – Local Super Clusters or Laniakea – Visible Observable or Known Universe – Cosmic Web – Infinite Space.
Project Vision:
This futuristic, innovative and imaginative theoretical white paper abstract dreams and aims at making a Self Guided
Escape Velocity Shuttle (SGEVS) a possibility and reality. This article outlines a vision policy statement for such vehicle or
shuttle.
This SGEVS could roam around infinite space jumping or hopping or navigating from one astronomical body in space to
other, could it be between Planets, Stars, Black Holes or Galaxies. Such travel is also called as interplanetary spaceflight or
interplanetary travel.
SGEVS is based on auto or self calculating and de-facto attainment of Escape Velocity of the 'Host' to reach the 'Destination
Target' in space.
Project Background:
In the current day scenario for launching a rocket into space and beyond, we need the following in a nut shell. This
infrastructure in its current form is not scalable enough for the launch of SVEGS and paves way for additional alternatives
marked by discoveries and innovations.
1. Launch Pad.
2. Compartment Modules - Alternating solid & liquid fuel Propellants.
3. Hot Module.
4. Satellite or Payload.
5. Control Command Centre or Base station.
6. Deep Space network of Dish Antenna’s for Navigational Trajectory & Guidance.
The Launch Pad is ignited by Nuclear Fuel to give the rocket, necessary initial thrust for takeoff.
After every few hundred or thousand kilometres, a compartment module is fired and released to give further thrust to the
rocket, for it to move upwards or in forward directions. The solidified and liquefied gases in compartment modules are
burnt or mechanically powered to give the rocket the necessary thrust from time to time.
2. Finally the Heat Module bursts open and launches the enclosed Payload i.e. a manned or unmanned satellite in the orbit of
the target i.e. Moon, Mars, Saturn or any other astronomical body to be observed.
The Rocket’s or the Payload’s location, speed etc are tracked through a Deep Space network of Dish Antenna’s for
Navigational Trajectory and course adjustments from Earth’s Command Control Centre or Base station.
Project Scope:
o Phase-1: Space Shuttle’s self guide to calculate and attain Escape Velocity.
o Phase-2: Self guide after Escape Velocity is reached.
o Phase-3: Self guide for Navigational Trajectory to reach destination location in space.
o Phase-4: Self guide for compact and comprehensive self healing and sustenance.
o Phase-5: Self guide for multi hops or jumps from one astronomical location to other in space (Host to
Target).
Not in Scope:
Current existing and futuristic approaches of design, functioning and integration of:
1. Hot Module, Alternating Solid and Liquid compartment chambers, Dish Antenna, Transponders, Gold
Foiling, Energy Panels, Protective shields & Masks, Computing & Processing power.
2. Docking procedures i.e. with or without human, remote and base station, Satellite controlled.
3. Alchemy solutions to process and convert available Compounds or elements in space or Host
environments to utility elements suitable for Human or space sustenance, though observations and
recommendations are made.
3. Abstract:
The design fundamentals of such an SGEVS could rely upon the enlisted:
1. Albert Einstein's Gravitational Force (Fgrav) calculations.
2. Isaac Newton's Universal Gravitational Constant (G).
3. Inertial Balance or Rotational Speed (w or omega Ω).
4. Tangential Speed or Angular Velocity (v).
5. Angular Momentum (L).
6. Escape Velocity Formula (ve).
7. Renewable Space Cryogenics – Solid & Liquid Fuel Propellants.
8. Astronomical Telescope - Integrated with SGEVS.
9. Laser Interferometry - For precise Distance Measurements.
10. Renewable Energy Generation for Human Survival.
11. Quantum Computing - For processing and sending/receiving data or information securely.
12. 3D Printing Integrations.
13. Legacy Modernization.
4. Approach:
(1). Force of Gravity between two objects in space can be calculated from:
Force of Gravity, Fgrav α (m1 * m2)/ d
2
m1 = mass of first object in space.
m2 = mass of second object in space
d = distance separating the object centres. Distance can be calculated from Laser Interferometry.
Calculating Mass of astronomical objects in space proves to be trivial.
(2). “Mass” Calculations:
Mass is the amount of matter in an Object. Weight of the object changes from planet to planet, but mass remains
the same. To measure mass in space, we use a kind of scale called Inertial Balance, based on Frequency of Vibrations of
the object and Speed of Rotation, Gravitational Interactions in case of Stars and Galaxies.
Rotational Speed (Or Speed of Revolution) of an object rotating around an axis is the number of turns of the object
divided by time, specified as revolutions per minute (rpm), revolutions per second (rps) or radians per second (rad/s). The
symbol is Omega ( w or Ω).
Ω or wrad = v/r or wcyc = 2πr
v = Tangential Speed or Angular Velocity.
r = Radial Distance.
Tangential Speed is linear speed associated with objects in space moving in a circular path and Angular Velocity that of
objects moving in various angles i.e. Circular path.
Tangential Speed, v = s/t;
s = Length of path travelled or distance travelled.
t = Time of travel.
Angular velocity is the rate of change of the position angle of an object with respect to time. The angular velocity of an
object is the object's angular displacement with respect to time. When an object is travelling along a circular path, the
central angle corresponding to the object's position on the circle is changing. The angular velocity, represented by w, is
the rate of change of this angle with respect to time.
Angular Velocity, W = θ/t;
θ = Position Angle.
t = Time;
Position angle, θ = s/r;
s = arc length.
r = radius.
So, Angular Velocity, W = s/ (rt);
5. (3). Angular Momentum (L) and Moment of Inertia (I) :
Angular Momentum, L = IW;
I = Moment of Inertia.
W = Angular Velocity, which we already know.
Moment of Inertia, I = mr
2
;
Here, r = distance to rotation axis;
Gyroscopes are in general used for measuring or maintaining orientation, the applications of which are inertial navigational
systems where magnetic compasses would not work, as in Hubble telescope.
(4). Escape Velocity:
Escape Velocity is the velocity that an object or shuttle or rocket needs to attain to avert the gravitational force of
the Host in space i.e. Earth or Moon or Star or Galaxy etc.
Escape Velocity of Earth is calculated as 40,000 Kmph or 25000 mph. A rocket needs to achieve this speed to escape from
Earth’s orbit and reach outer space.
Escape Velocity, ve = √(2GM)/r;
G = Newton’s Universal Gravitational Constant, which remains the same where ever you go in universe.
M = Mass of Object.
r = distance between two mass centres.
(5). Renewable Space Cryogenics –Solid & Liquid Fuel Propellants:
Extremely low cooled Cryogenic Liquid fuels acts as Mechanical Power and Combustive ignition propellants to give
the necessary and desired upward, angular, circular moment to the Rocket or Shuttle or Vehicle to achieve the necessary
escape velocity and anticipated speeds at different levels in space or beyond.
The Large Hydron Collider (LHO) used in LIGO (Laser Interferometer Gyroscopic Observatory) project is the largest
Cryogenic system in the world operating at -271.3 Degree Centigrade, colder than outer space (-270.5 Degree Centigrade).
If the inert liquid fuels like Helium, Nitrogen, Argon, Methane, Krypton, Neon etc. and hypergolic propellants
like UH25 (75% UDMH - Unsymmetrical dimethylhydrazine and 25% hydrazine hydrate), MMH (Monomethylhydrazine)
provide the Mechanical Power , certain others like Oxygen, Nitrogen, Hydrogen, LNG (Liquefied Natural Gas), when
ignited gives the combustive boost for the object under launch. Also solid propellant boosters like Aluminium Powder
are used.
While the above techniques are in vogue are generally accepted for long, the need of the hour for SGEVS would be
to generate such Cryogenic Energy, Oxidizers and Binders from Space and Host environments post launch, while in
trajectory or while orbiting in space or while at rest.
Even if found in compound state in the Host environment, the ability to extract the elements out of them and to
liquefy them or powder them using advanced techniques and technologies if already not done is the key challenge. The
6. goal should be to miniaturise such process efforts and accomplish the same in short time. Harnessing the power of
naturally available energy sources in Space and reaping their benefits is of utmost importance for the success of SGEVS.
Large amounts of powerful Radio Energy are emitted by Quasars and by Lobes of Radio Galaxies outside of Milky
Way. Most of the stars in several Galaxies are made up of Hydrogen and Helium.
Re-generated energy fuels from processing Human Faeces and ‘Host’ rains as mentioned in further sections of
this document can be leveraged.
Like in Earth as we have fuel filling stations for Automobiles, Air Borne vehicles etc., we need to build fuel filling
stations, service stations or Pit-stops in space and in host environments of Planets etc, so that SGEVS can stop by and re-
vitalize.
Also instead of the generally used Solar Panels, advanced Energy Panels that identifies various sources and
translates energy derived from Wind, Light, Solar, Tidal, Hydel, Debris, Fossils, Mist, Dew, Space Matter, Anti-Matter into
Electrical Energy needs to be identified, created, integrated and miniaturized for the success of SGEVS.
In the current day scenario, a space bound rocket or shuttle doesn’t integrate with it a Nuclear reactor to trigger
Fission or Fusion reactions to give it the necessary thrusts at various points in time after covering certain astronomical
distances. A backward displacement strategy of releasing Compartment Modules is used. Ways and means to Identify
Nuclear Reactor integrations with rocket has to be explored.
(6). Astronomical Telescope - Integrated with SGEVS:
One or more set of Compact, Light Weight, High Frequency, and Miniaturized Astronomical Telescopes needs to be
integrated with SGEVS to capture pictures, videos and other vital signs at an amazing and brisk speed to be sent back to the
base station for analysis and processing.
Also Astronomical Radio Telescope detects Radio Waves emitted by Starts, Galaxies, Nebulae and other
Astronomical bodies.
(7). Laser Interferometer - For precise Distance Measurements:
In the due course of above cited calculations involving distance measurements to arrive at Escape Velocities
from time to time depending on the Host and Target locations, Laser Interferometers can be used for precise and
accurate distance measurements.
(8). Renewable Energy Generation for Human Survival:
The survival instincts of Human habitat in different parts of world since evolution needs to be
thoroughly researched and tabulated, to arrive at methods to mimic extremely low consumption, utilization and
longer healthy living in space.
If an advanced version of SGEVS anticipates to carry Human’s along with the usual shuttle or rover or satellite
payload, then instead of carrying Oxygen, Water and Food Capsules from Earth or base station, these needs to be
generated internally through Renewable Energy Generation methods like we do on earth.
Thunderstorms, Lightning and Rains occur in Ionosphere as well. Also in some ‘Hosts’ i.e. planets, their if not
Water (H2o), other compound or elemental liquid remains/marks/stains of liquid methane, sulphuric acid drops,
7. helium drops, nitrogen snow, ethane due to rains of that nature are found. Plethora of Alchemy technology solutions
needs to be discovered or invented with extensive research to use them for Human and Shuttle survivals.
Rainwater Harvesting Shuttles or Satellites (RHS) needs to be operated in Earths outer environment
(Ionosphere), to ensure continuous supply of water (H2o) to SGEVS and other manned space shuttles either in
several orbits of Earth or beyond. The successful launch of RHS proves to be vital to realize future human habitation
on MOON, MARS or any other ‘Hosts’.
Similar approaches as described in Renewable Space Cryogenics topic can be explored in addition to generating the
same from Human wastes or Human Feces (Solid or Semi-solid metabolic waste) like Excretion/Sweating, Mucus, Urine,
Sputum, Siemens etc.
An Indian philosophical and spiritual saying is “Nava Dwaara Pure Sareeram”, this body constitutes 9 holes. All the
Feces generated from 9 holes based on their mass, size, colour, texture, viscosity and other composition filters needs to
be segregated and treated back to generate the needs of Water, Oxygen and Food Capsules or Granules. A positive
feedback system of that sort is quite essential for a longer journey in space whilst travelling across new worlds.
Eg: Morarji Desai and several others in ancient/olden days used to consume their own urine, an internal bodily
positive feedback system. Astronauts and Cosmonauts of manned SGEVS ought to be trained, of course after some
filtering.
NASA is developing a complex, expensive and, as it turns out, somewhat buggy machine that purifies human
urine to recycle the water for astronauts to drink.
Michael Hoffmann’s Gates Foundation uses solar power to break human waste into hydrogen gas and leftover
solids. Hoffman and his team at Caltech showed how the toilet could store hydrogen in fuel cells as an energy source. The
toilet treats waste on the spot and siphons off hydrogen for later use as energy.
In a unique variation of biogas production from human waste, researchers at Delft University of Technology have
worked out a way to produce synthetic gas – “syngas” – which is a mixture of carbon monoxide and hydrogen. Their Gates
Foundation award- winning design dries the waste on the spot and zaps it with microwaves to heat it into plasma for
gasification (all proprietary technology). Then the toilet stores the gas in a solid state fuel cell stack to produce electricity.
Certain other use for human waste is Fuel briquettes. Not compost, not biogas or hydrogen fuel cells, but actual,
burnable fuel made from treated human waste. Researchers from the University of Colorado in Boulder won a Gates
Foundation grant to develop a solar-powered toilet that turns waste into bio char.
Researchers from RTI International in North Carolina won a Gates Foundation grant for their toilet design that
converts waste into fuel briquettes that it burns for storable energy. It also churns out treated, but non-potable, water.
Urine has been used as a disinfectant, invisible ink and dye for cloth, and both urine and faces are necessary to
diagnose certain illnesses and parasitic infections
If in the worst case none of these Human Feces can be reused for self, then owing to their high combustive value
they can be used as a Solid or Liquid or Combustive gaseous propellants after necessary filtering and extraction process.
(9). Quantum Computing - For processing and sending/receiving data or information securely:
The latest advancements of Quantum Computing to transfer huge amount of data and achieve high speed,
secure data transfers needs to be leveraged for all inter and intra communication and interaction purposes i.e. within the
shuttle, with other objects in space and with Earth.
8. (10). 3D Printing Integrations:
To replace the damaged and lost vital minor components in the due course of the Shuttle’s long space journey, it
needs to be integrated with 3D printing machines to rapid prototype and create the parts and fix them back with a mini
robot or the human in the shuttle. This makes the shuttle self healing.
The International Space Station's 3-D printer completed the first phase of a NASA technology demonstration by
printing a tool with a design file transmitted from the ground to the printer. The tool was a ratchet wrench.
NASA is exploring how the microgravity environment may benefit how objects are designed and built in space
for parts that cannot be made on the ground. The printer made one object that is extremely difficult to make on the
ground because of sag caused by gravity. In addition to the wrench, the printer made objects with 13 different designs
and built a total of 20 objects, making some items more than once. Except for the ratchet, the other 19 objects were
pre-programmed into the printer before it left Earth.
(11). Legacy Modernization:
Technology Convergence drives Legacy Modernization initiatives in space missions.
Leveraging the advanced “Internet of Things (IOT)” sensors to capture and measure vital space environment parameters
which might be at feeble or lower frequency ranges. IoT concepts extended to space are called Infinity of Things.
Typically, data communications within satellites are transmitted through wired connections, but as part of a ‘wireless-in-
space’ effort, NASA is working to improve traditional wiring with wireless networking to reduce weight, increase payload
capacity and create new communication models.
”Big Data” driven applications to store numerous of those captured parameters and applying contemporary Predictive
Analytics and Artificial Intelligence(AI) Solutions holds the key for success of the SGEVS.
Needless to say that Quantum Super computing power (HPC – High Performance Computing) has to be utilised for
complex computations, calculations and also for security purposes to reap the benefits of high speed processing and
robust communications.
