Celebrating the year of light with a slideshow of light activities at Interlochen Center for the Arts. Slideshow is displayed on a wall of the Bonisteel Library.
Nicolaus Copernicus first proposed that the Earth and planets revolve around the Sun, contradicting the accepted model of Ptolemy and Aristotle of Earth as the center of the universe. Major developments included Galileo's use of the telescope to observe moons orbiting Jupiter and rings around Saturn, and Isaac Newton's formulation of the law of gravity. Modern space exploration began with Sputnik I and has involved satellites providing communication, weather monitoring, navigation, and other applications as well as human missions to orbit and walk on the Moon.
This document summarizes the career of Roger D. Cooper as a "Rocket Man" involved with the British National Space Programme over 15 years. It describes his role assisting scientists with designing instruments to study cosmic events from space. Key experiences included designing payloads carried by Skylark rockets above the Earth's atmosphere. Payloads contained experiments using x-ray detectors and telescopes to discover new information about space phenomena. The document provides details on the rocket design and launch process, and Cooper's involvement in several missions that made discoveries in astrophysics.
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.
Satellites have evolved significantly since Sputnik was launched in 1957. Early satellites were simple devices that gathered basic data and demonstrated orbital technology, while modern satellites can cost over $1 billion and provide advanced capabilities like global communications, weather monitoring, and GPS. However, the growth of space debris is a emerging environmental issue as defunct satellites and fragments threaten future space exploration due to collisions.
Astronomy is the scientific study of celestial objects and phenomena outside the Earth's atmosphere, while astrology is the pseudoscience claiming to divine information about human affairs based on the positions of stars and planets. Early astronomers like Ptolemy, Copernicus, Tycho Brahe, and Johannes Kepler made observations and developed models of the universe that established astronomy as a science. Galileo Galilei was one of the first to use a telescope to observe craters on the Moon, moons of Jupiter, and sunspots, advancing the field. Modern astronomers use powerful optical and space telescopes to study distant galaxies and probe deeper into space.
Black holes are formed when massive stars over 10 times the size of the sun explode at the end of their life in supernovae. This leaves behind an extremely dense object with strong gravity that collapses in on itself to zero volume. Scientists can find black holes by measuring light like x-rays and radio waves from matter around it, and by tracking the orbit and speed of stars near the black hole to determine its gravitational pull.
Space probes are unmanned spacecraft that collect science information from locations in space without astronauts. They carry instrument packages to conduct scientific experiments and transmit data back to Earth. Probes can fly by, orbit, or land on planets, moons, asteroids, and comets to study features from a close proximity. Some notable space probes include Voyager 1 and 2, Galileo, Cassini, Curiosity, and probes launched by ISRO to study planets in our solar system.

Some notable space probes include Voyager 1 and 2, Galileo, Cassini, Curiosity, and probes launched by ISRO to study planets in our solar system.
The document summarizes information about the planets in our solar system. It describes the four inner, terrestrial planets - Mercury, Venus, Earth, and Mars - and their small, rocky compositions. It then discusses the four outer, gas giant planets - Jupiter, Saturn, Uranus, and Neptune - noting their large sizes and gaseous compositions. It also mentions other bodies like asteroids, Pluto, and the Kuiper Belt.
Space probes are uncrewed spacecraft that carry scientific tools to study planets and other bodies in space, as they can complete missions too dangerous or expensive for humans. Key probes include Luna 9, the first to soft land on the moon; Venera 9, the first on Venus which found rocks similar to Earth's and intense heat; and the Viking missions, which searched for life on Mars and found it was once warmer. Galileo and Cassini were the first probes to the outer planets, with Galileo discovering Jupiter's moons may have liquid water and magnetic fields.
The Upper Atmosphere Research Satellite (UARS) was launched in 1991 to study the ozone layer. It collected data that showed levels of ozone-depleting chemicals had stabilized by 2005, when UARS was decommissioned after exceeding its planned 3-year mission lifetime. As a satellite's orbit decays due to drag from solar wind and atmosphere, it is difficult to predict exactly where it will re-enter and debris will land, within a margin of about 4,280 miles, due to uncertainties from atmospheric effects.
Space craft,space probe,space station,space shuttle and rocketCryptic Mae Lazarte
This document defines and describes five key space-related terms: spacecraft, space probe, space station, space shuttle, and rocket. It explains that spacecraft are vehicles designed to operate in outer space and are used for purposes like communication, exploration, and transporting humans. Space probes are scientific exploration missions that leave Earth to explore other areas of space. Space stations are spacecraft designed to remain in orbit for extended periods and support human crews, while relying on other vehicles to transport people and cargo. The space shuttle was a partially reusable spacecraft operated by NASA to transport people and cargo to and from low Earth orbit. Rockets use carried propellants and the thrust from rocket engines to push themselves forward by expelling exhaust rearwards very fast.
The document discusses several futuristic models for space travel, including solar sails that use radiation pressure to propel large mirrors, nuclear pulse propulsion that uses nuclear explosions in stages to accelerate to near light speed, and warp drive which uses gravitational effects to compress and expand space-time to allow for faster-than-light travel. Current research projects exploring these concepts are mentioned, with the implication that sci-fi technologies like warp drive may become reality within the next 50 years.
ILOA Galaxy Forum Hawaii 2014 -- Waimea -- Phil MerrellILOAHawaii
The International Lunar Observatory Association (ILOA) is a non-profit organization incorporated in Hawaii that aims to advance human understanding of the cosmos through astronomical observation from the Moon, including studying galaxies, searching for exoplanets and signs of life, as well as coordinating education initiatives like the Galaxy Forum to increase global awareness of galaxy science. ILOA has collaborated with China on lunar missions and plans its own ILO series of lunar orbital and surface missions beginning in 2013 to establish an observatory on the Moon's south pole.
Sun prominences are huge clouds of glowing hydrogen gas that erupt from the sun's upper atmosphere. They appear as large red flames or streamers extending outward from the sun's surface. Sometimes prominences erupt violently, shooting solar material far out into space. Prominences can extend for hundreds of thousands of kilometers and last for several months before dissipating back into the sun. They are best seen during a solar eclipse or by using special telescopes to observe their bright spectral lines.
This document presents a seminar on space debris given by Lokesh Parihar to Anurag Garg. It begins with an introduction defining space debris and its history. It then discusses the different types of orbits where debris can be found, such as low Earth orbit and geostationary orbit. The document outlines methods used to track and measure debris including radar, radio waves, and space telescopes. Potential methods to clear space debris are presented, including electrodynamic tethers, laser brooms, solar sails, space nets, and collector satellites. The conclusion emphasizes the importance of addressing the growing problem of space debris to enable continued development of space communication and exploration.
Astronomy is the scientific study of objects and matter beyond Earth's atmosphere. There are four main types of astronomy: astrophysics, astrometry, astrogeology, and astrobiology. Astronomers study the origin and workings of the universe and its objects. Some core subjects in astronomy include physics, mathematics, quantum mechanics, and electromagnetic waves. To become an astronomer requires at least a bachelor's degree in astronomy, physics, or a related field, which provides the necessary scientific skills and knowledge. Astronomy involves scientific observation and study, whereas astrology involves the belief that the positions of the stars and planets can affect human lives.
This presentation discusses space, satellites, and their uses. It defines space as the three-dimensional extent in which objects exist and events occur, and defines a satellite as an object placed in orbit by human effort. It provides examples of different types of satellites, including weather satellites that take pictures of clouds and oceans from space, and science satellites that help scientists learn about space and discover new planets. It also briefly describes asteroids as small solar system bodies that are not comets.
1) A black hole is a region of space where gravity is so strong that not even light can escape. They form when a large star collapses in on itself.
2) Black holes cannot be seen directly because no light escapes, but they can be detected by their interaction with nearby stars.
3) Black holes come in different sizes, from small stellar black holes to supermassive black holes millions of times the sun's mass that are found at the centers of galaxies.
The document discusses key facts and figures about the International Space Station (ISS). It provides statistics on the number of spacewalks, launches, pressurized volume, weight in orbit, meals eaten, lines of code, power generated, and people involved. It lists 59 countries that have participated in ISS utilization and research accomplishments from Expeditions 0-24, including the number of investigations conducted, completed, led by international partners, and from national labs. Scientific publications from research on the ISS are also mentioned.
Astronomy is the study of anything outside Earth's atmosphere. It began as people observing the sky to track the seasons. Today, astronomers use various tools like telescopes, satellites, and probes. There are about 15,000 professional astronomers worldwide and 300,000 amateur astronomers in the US. Amateur astronomers make observations and discoveries. Astronomy includes areas like observational astronomy using different wavelengths of light, celestial mechanics of planetary motion, and theoretical astronomy of developing models.
The Wilkes Land Crater is the largest impact crater ever discovered on Earth, located in East Antarctica. It was formed approximately 250 million years ago by a meteorite that was 50 kilometers wide. At 483 kilometers wide, it is larger and older than the Chicxulub crater associated with the extinction of the dinosaurs. The Wilkes Land Crater was discovered in 2006 using NASA gravity radar and would have caused massive damage when it impacted due to its enormous size. It may have contributed to the largest mass extinction event on Earth, the Great Dying in the Permian period.
Percival Lowell was convinced of a ninth planet beyond Neptune. In 1930, Clyde Tombaugh discovered Pluto at Lowell Observatory. Pluto is the smallest and coldest planet, taking 248 Earth years to orbit the Sun. It has a thin atmosphere and five moons, including its largest Charon. In 2006, the IAU classified Pluto as a dwarf planet due to its small size. The New Horizons spacecraft will fly by Pluto in 2015 on its way to the Kuiper Belt.
To get an object into space, it must reach a speed of 28,000 km/h to overcome Earth's gravity. The first recorded rocket was Archytas's "pigeon." The Soviet Union launched Sputnik I in 1957, the first artificial satellite about the size of a basketball. The second Soviet satellite was significant because it carried living creatures into space, setting the path for human space travel. Rockets use Newton's third law - for every action there is an equal and opposite reaction - to propel themselves by ejecting exhaust in one direction. The three main parts of a rocket are the payload, propellant, and engines. Scientists are studying ion drives and solar sails as alternatives to rocket engines for long
This document discusses satellites and spacecrafts. It provides definitions of spacecraft as vehicles designed for travel outside Earth's atmosphere and satellites as spacecraft that orbit Earth or other celestial bodies. The document then covers the history of spacecraft from Sputnik being the first artificial satellite launched by the Soviet Union in 1957. It also discusses different types of manned spacecraft, spaceplanes, satellites in orbit, the services provided by satellites, types of satellites, and the role of NASA.

ILOA Galaxy Forum Canada 2015 - Paul HicksonILOAHawaii
-- Large optical telescopes on the Moon – Paul Hickson, Professor, Department of Physics and Astronomy, The University of British Columbia.
The Moon offers some unique advantages for future very-large optical telescopes. The airless environment, slow lunar rotation and precession would enable a zenith-pointing telescope, located near one of the lunar poles, to survey a large region of sky and study the epoch of galaxy formation. I will present results from a recent NASA/CSA study that considered the feasibility of lunar liquid-mirror telescopes having apertures in the 20 to 100 metre range.
Citizen science projects have the potential to transform earthquake detection by greatly increasing the number of seismic sensor locations. Individuals can host sensors in their homes and buildings to record ground motion data during quakes. However, data quality standards must be maintained and networks need to remain operational long-term for the data to be scientifically useful. If these challenges can be addressed, dense citizen sensor networks may provide new insights into earthquake processes.

The document summarizes findings from studying asteroid 4 Vesta using data from NASA's Dawn spacecraft. It finds that Vesta has experienced a violent collisional history, with large impacts creating steep slopes and resurfacing much of the surface. While no unambiguous volcanic deposits were found, some dark material in impact craters may be from excavated subsurface volcanic features. Smooth ponds found on Vesta are also seen on asteroid Eros and are thought to form from impact ejecta collecting in depressions.

The article discusses observations from multiple space-based observatories that tracked a sun-diving comet, C/2011 N3 (SOHO), as it passed through the Sun's corona and disintegrated. The observatories captured details of the comet's flight path, emissions, and disintegration over time. Studying how comets interact with and break apart in the corona can provide insights into comet composition and the early solar system.

NASA's Jet Propulsion Laboratory - 2012 Annual reportJon Nelson
Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center located in Pasadena, California, United States.
JPL is managed by the nearby California Institute of Technology (Caltech) for the National Aeronautics and Space Administration. The laboratory's primary function is the construction and operation of robotic planetary spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA's Deep Space Network.
Among the laboratory's current major active projects are the Mars Science Laboratory mission (which includes the Curiosity rover), the Cassini–Huygens mission orbiting Saturn, the Mars Exploration Rovers (Spirit and Opportunity), the Mars Reconnaissance Orbiter, the Dawn mission to the dwarf planet Ceres and asteroid Vesta, the Juno spacecraft en route to Jupiter, the Gravity Recovery and Interior Laboratory (GRAIL) mission to the Moon, the Nuclear Spectroscopic Telescope Array (NuSTAR) X-ray telescope, and the Spitzer Space Telescope.
This was a talk I gave at CU Boulder SEDs in Nov 2011 to showcase the variety and opportunities for student-run science and engineering experiments on suborbital platforms. The area of suborbital space is rapidly expanding and is set to change how we expand our use of technology for future science and exploration space missions.
The document provides information about NASA's STEREO mission to study the sun and solar phenomena like coronal mass ejections. It includes an overview of the STEREO mission objectives, the two spacecraft and their instruments, and frequently asked questions about the mission. The goal is to obtain the first 3D stereoscopic views of the sun to better understand solar eruptions and aid in space weather forecasting, which can impact satellites, power systems and astronauts. The twin STEREO observatories will be placed in orbit on opposite sides of Earth to view the sun from different vantage points and gather data over a planned two-year mission.
The weather satellite was invented by a group of scientists and engineers working for NASA, not a single person. On April 1, 2000, NOAA launched the first weather satellite, which was composed of GOES and POES satellites that provided full Earth coverage and processed collected data. Weather satellites use radiometers to scan the Earth and detect radiation to monitor weather, transmitting data to ground stations within a minute for meteorologists to track patterns and make forecasts. They can operate for 3 to 7 years in either geostationary or polar orbits.
This document discusses the interrelated topics of evolution, astronomy, and paleontology.

Dust production and_particle_acceleration_in_supernova_1987_a_revealed_with_almaSérgio Sacani
This document presents spatially resolved submillimeter observations of supernova remnant SN 1987A using the Atacama Large Millimeter/Submillimeter Array (ALMA). The observations reveal that at longer wavelengths (2.8 mm - 1.4 mm), the emission is from a torus associated with the supernova shock wave, while at shorter wavelengths (870 μm - 450 μm) the emission is dominated by the inner supernova ejecta. For the first time, the dust emission is unambiguously shown to originate from the inner ejecta rather than from the surrounding material, supporting theoretical models of significant dust production in supernovae. The observations also allow separation of synchrotron emission from shock-accelerated particles in
This document provides an overview of some of the boldest space missions in history, including the Parker Solar Probe mission, SpaceX missions, Voyager missions, and the Apollo missions.
