Weather satellites were invented by NASA scientists to scan images of Earth using radiometers, which measure temperature and cloud cover. The satellites orbit Earth, completing a full rotation every 24 hours to monitor global weather patterns and conditions. They provide data on cloud cover, storm locations, atmospheric temperature and heat balance.

Weather satellites period 3
Weather satellites can be either geostationary or polar orbiting. Geostationary satellites orbit above the equator at high altitudes and rotate with the Earth, while polar orbiting satellites circle the poles at lower altitudes. Weather satellites detect data using visible and infrared spectrums to measure cloud cover, temperatures, and weather systems to aid forecasting. Some of the first experimental satellites included Vanguard-2 and TIROS-1, though TIROS-1 was the first successful weather satellite launched by NASA.
Weather satellites
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.
Weather satellites pd. 5
The first weather satellite was TIROS-1, created by a team at NASA in 1960 without a single inventor. Weather satellites use radiometers with detectors for infrared, microwave, and visible light to take images from orbit. They provide data on clouds, temperatures, storms, and other weather patterns up to every 12 hours. Infrared satellites in particular help fishermen and farmers by detecting tropical cyclones and calculating surface temperatures. All weather satellites have exterior imaging devices like radiometers and often use solar panels to generate power.
Meteorologcal application of satellites
The document discusses the use of meteorological satellites, weather balloons, and sounding rockets for weather forecasting. It provides background on severe weather events that have caused major damage, highlighting the need for improved forecasting. It then describes some of the first meteorological satellites, including TIROS-1, which was the first to transmit cloud photos from space. It also discusses the NIMBUS satellites, which had improved coverage over the TIROS satellites and helped enable long-term observations of phenomena like the ozone hole.
Satellites
Satellites are objects built and sent into Earth's orbit that transmit information to ground stations via radio waves. Communication satellites made wireless communication cheaper than telephone lines in the early 20th century by using digital systems. Weather satellites in geosynchronous orbit provide 24-hour monitoring of specific areas, while other satellites not in this orbit can track ships and fires from low Earth orbit. Remote sensing satellites in low orbit take images of the Earth's surface to send data on heat, resources, and urbanization. GPS satellites accurately track locations within a few meters via radio signals.
Planets & other objects in solar system
1) The protoplanet hypothesis explains the formation of solar systems with three steps - a cloud of dust and gas begins swirling, most material accumulates to form the sun, and remaining material forms smaller clumps that become planets.
2) The sun is over 100 times wider than Earth, could fit 1 million Earths inside if hollow, has a surface of 5500°C and a core of over 15 million °C. It gives off charged particles called solar wind that flows at around 400 km/s, protecting Earth with its magnetic field.
3) The planets are divided into inner, terrestrial planets like Mercury, Venus, Earth and Mars that are smaller, rockier and closer to the sun,
Tools used by astronomers (au + lightyears)
Early astronomers used tools like the sundial, merkhet, quadrant, astrolabe, and cross-staff to measure the passage of time and the positions of stars and other astronomical objects. The telescope, invented in the late 16th century, revolutionized astronomy by allowing astronomers to observe celestial objects in greater detail. Units like the astronomical unit (AU) and light-year provide standardized measures for distances within our solar system and across the wider universe.
Satellite systems landsat 7 compatibility mode
The document summarizes information about satellite systems, with a focus on the Landsat program. It discusses that Landsat 1 was launched in 1972 and started the Landsat program for collecting remote sensing data of Earth. Landsat 7 is the most recent satellite, launched in 1999, and it collects global images with improved technology to refresh the satellite image archive. The document also provides details on the sensors and applications of Landsat 7 for monitoring Earth's environment, geology, natural resources, and land use from its sun-synchronous polar orbit.

Mars
Mars is an extreme planet that offers little hospitality to visitors. It has the largest volcano in the solar system, the deepest canyon, and unpredictable weather and temperatures. The Phoenix spacecraft launched in 2007 to study the northern polar regions of Mars, where water ice is found. It landed successfully in 2008 and spent over 150 Martian days digging trenches and analyzing soil samples to search for organic compounds that could indicate the possibility of past life. Phoenix carried instruments to study the atmosphere and scan as high as 20 km to observe cloud and dust activity.

Mars is an extreme planet that offers little hospitality to visitors due to its arid, rocky, and cold conditions. It has the largest volcano in the solar system and crazy weather patterns, posing challenges even to extreme sports enthusiasts. The Phoenix spacecraft launched in 2007 to study Mars' northern polar regions and search for water ice and organic compounds, landing in 2008. It has an oven and laboratory to analyze soil samples from trenches dug by its robotic arm up to 1.6 feet deep to study seasonal climate changes in the water ice layers. Phoenix also scans the atmosphere and measures temperature and pressure.
Views of nature of earth and space
Ancient sites like Newgrange Passage Tomb and Stonehenge were carefully aligned with astronomical events like solstices and equinoxes, suggesting their builders had knowledge of the movement of celestial bodies. Early models of the universe placed Earth at the center, with the geocentric model proposed by Aristotle and later displaced by Copernicus' heliocentric model placing the Sun at the center. Kepler later improved on this by discovering planetary orbits were elliptical rather than circular in shape.
Astronomy
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.
Voyager
This is an insight into the voyager mission that remains to be the farthest man made satellites in space from Earth
Artifitial satellite
The document provides an overview of artificial satellites, including their history, types, components, and importance. It discusses key events like the launch of Sputnik 1 (the first artificial satellite) and describes different types of satellites such as scientific research satellites, weather satellites, communications satellites, navigation satellites, Earth observation satellites, and more. It also provides lists and details about artificial satellites launched by India, including their launch dates and purposes.
Voyager 1
Voyager 1 was launched in 1977 to take advantage of a rare alignment of the outer planets. It conducted flybys of Jupiter, Saturn, Uranus, and Neptune, and was designed to last 5 years but is still operating over 35 years later. Voyager 1 carries instruments to study the solar system and a Golden Record with photos and sounds of Earth. It has traveled over 18 billion km from Earth and will be the first human-made object to leave the solar system.
Hazards of space
There are significant hazards associated with space travel and operating in space. Three NASA space shuttle missions resulted in crew fatalities, with the Challenger and Columbia disasters killing all astronauts on board during launch and re-entry respectively. Once in space, debris from old satellites and other objects pose collision risks, while the human body is affected by microgravity with muscle and bone loss without gravity. Life support systems are needed to create earth-like conditions for breathing and environmental factors in space. Space junk, or debris left from old satellites and spacecraft, poses a continual collision threat as there are millions of objects orbiting Earth at high speeds.

Artificial satellite
Artificial satellites are used for telecommunication by acting as relay stations for radio signals between two points on Earth that are too far for direct radio transmission. The document discusses how satellites work by receiving uplink signals from one Earth station and transmitting the converted signals back down to another Earth station via downlink. It notes the first artificial satellite, Echo 1, was launched in 1960 and how geostationary satellites appear stationary in the sky from Earth's perspective, allowing ground antennas to remain fixed. The document also covers frequency bands used by different satellite types and applications of satellite communication technology for telephone and television transmissions.
Soar system
1) The document discusses astronomy topics including the definitions of year, month, and day based on Earth's movement. It also summarizes historic theories on the structure of the universe from Ptolemy to Hubble.
2) Telescope types including refracting, reflecting, and non-optical telescopes are explained. The Hubble Space Telescope is given as an example of an orbital telescope.
3) The document covers constellations, how the night sky changes through the seasons, and methods for measuring distance in space including light years.

Mercury hanhan
Mercury is the closest planet to the Sun and has the shortest year of any planet. It rotates once every 58 Earth days. Mercury has a very thin atmosphere and experiences extreme temperature variations between day and night, with daytime temperatures reaching up to 840°F and nighttime temperatures dropping as low as -275°F. Mercury has a heavily cratered surface and its interior is mostly metallic iron and rock.
Voyager mission
The Voyager program launched two probes, Voyager 1 and 2, in 1977 to study Jupiter, Saturn, Uranus, and Neptune. During their "Grand Tour" of the outer planets, the probes discovered many details about the planets and their moons, such as volcanoes on Jupiter's moon Io. After completing their primary mission in 1989, the Voyagers continue their journey into interstellar space, having sent back over a trillion bits of scientific data. They carry a "Golden Record" containing sounds and images selected to portray the diversity of life and culture on Earth to any intelligent extraterrestrial entities who may find them.

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 document discusses the 25th anniversary of the Hubble Space Telescope and how NASA's Goddard Space Flight Center celebrated. It provides details on events held at the Newseum in Washington D.C. and tours given at Goddard, highlighting Hubble's scientific achievements. Goddard leads Hubble operations and was instrumental in its development and ongoing missions. The anniversary is an opportunity to look to the future James Webb Space Telescope, intended to further discoveries beyond what Hubble can achieve.
Rigel Exoplanet Geologist
The next great objective in Space is the surface exploration of a planet orbiting a distant star.
The Robotic Interstellar GEologicaL probe, RIGEL, is designed to land on an exoplanet and roam across its surface. This will be a logical follow-on to space telescope surveys and flyby missions. The engineering challenge that this presents is one reason that the RIGEL project should be initiated promptly. The hurdles are immense, but the prize is worth the effort. For the first time in history, an explorer from the Earth will be able to walk about the surface of an alien planet. That explorer will be a machine, a proxy for mankind.
Besides geology, Rigel will also analyze any life on its target world. There are investigations that can only be conducted in-situ. For example, if there are plants which use stellar light (sunshine) as an energy source, the structure of their photosynthesizing pigment can only be determined by directly analyzing the plant structure.
[Challenge:Future] Space Debris
Space debris in low-Earth orbit poses a serious and growing threat. There are over 22,000 pieces of debris larger than 10 cm currently orbiting Earth, traveling at speeds sufficient to damage satellites. If left unchecked, the amount of debris will continue to grow exponentially through collisions in a process known as the Kessler Syndrome, which could render space exploration and satellite use impossible for generations. Solutions require both mitigation efforts to limit further debris creation as well as active removal of existing debris through methods like lasers, electromagnets, or debris-capturing space structures. International cooperation will be needed to implement solutions and avoid a space debris disaster.

A team of scientists would send rovers to Titan equipped with seismographs and gas chromatographs. One rover would measure any increasing distance between itself and others around Sotra Facula, an potential ice volcano, to detect divergent plate movement. Seismograph recordings could map plate boundaries. Drill cores would reveal stratigraphic unconformities indicating geological disruption. Gas analysis of trapped air in ice cores could show past atmospheric composition changes linked to volcanic outgassing, providing evidence of an active resurfacing mechanism like plate tectonics on Earth.

This document proposes a mission to study evidence of plate tectonics on Titan through four experiments. A team of scientists would send rovers equipped with seismographs and gas chromatographs to the site of a possible ice volcano. The first experiment would use signals between rovers to detect divergence at the volcano, indicating a plate boundary. The second would map ice-quakes to identify plate boundaries. The third would examine stratigraphy for unconformities from plate movement. The fourth would analyze ancient air from ice cores to study past atmospheric composition. Finding plate tectonics on Titan could provide insight into its importance for life, as it generates biodiversity and climate effects on Earth.

Article 1 for Sept 16
Astronomers observed extreme brightness changes in a nearby brown dwarf, indicating a massive storm greater than any seen on planets. The brightness of the brown dwarf changed 30% in under 8 hours, suggesting evolving cloud patterns on its atmosphere. Studying how quickly these cloud features change could provide insights into atmospheric wind speeds and weather phenomena on extra-solar planets, which have similar atmospheres to old brown dwarfs and giant planets. This finding provides new perspectives on atmospheric conditions outside our solar system.

Radial velocity measurement, which detects tiny wobbles in a star's motion caused by an orbiting planet, was the first technique used to detect exoplanets in 1995. It remains a primary method and has discovered hundreds of planets by measuring changes in the star's spectrum over many observations. The Kepler space telescope has also found thousands of planet candidates using the transit method, which detects dips in a star's brightness when a planet passes in front. Other techniques like astrometry, microlensing, and direct imaging aim to directly image planets, but have had limited success so far due to the huge contrast between planet and star signals. Future space telescopes may enable direct imaging and characterization of Earth-like exoplanets.

The solar system formed 4.6 billion years ago from a cloud of gas and dust left over from exploded stars. Over time, the cloud contracted due to gravity, causing the center to heat up and form the Sun. A rotating disc of debris remaining around the Sun eventually coalesced under gravity to form the planets. The inner rocky planets like Earth formed close to the Sun, while the outer gas giants like Jupiter were able to capture lighter gases further from the Sun. For over 1,400 years, the geocentric model of Aristotle with Earth at the center was accepted, but observations by Copernicus, Galileo, Kepler, and laws established by Newton provided compelling evidence that the Sun, not Earth, is at the center of

This document discusses various cloud formation processes and types of precipitation. It explains that temperature changes during cloud formation can be adiabatic. Orographic lifting and frontal wedging are processes where air is forced to rise over geographic features or air masses. Convergence and localized convergence involve the coming together of air masses. Condensation allows water vapor to change to liquid water droplets. The main cloud types are categorized by height as high, middle, and low clouds. Fog forms through similar cooling processes as clouds near the surface. Cold cloud precipitation involves freezing nuclei while warm cloud precipitation relies on collisions. Rain, snow, sleet, glaze and hail are different forms of precipitation.

When air rises and expands, it cools through adiabatic processes. This cooling can cause water vapor in the air to condense into clouds and precipitate out as rain, snow, sleet or hail depending on temperature levels. Clouds are classified based on their height and physical structure into cirrus, altostratus and nimbostratus clouds that form at high, middle and low altitudes respectively.
3jlaubach
Unequal heating of the Earth's surface causes air temperatures to change without a change in energy. This leads some parts of the Earth to be warmer or cooler than others. When warm air rises and is blocked or forced upward by cooler air, various cloud types can form through condensation. Precipitation occurs through processes like collision-coalescence in warm clouds or Bergeron process in mixed-phase clouds, forming rain, snow, sleet, hail, or freezing rain depending on temperature.
