Topic: Orbit
MAVEN launched in November 2013 and entered the Martian atmosphere roughly a year later. Since that time, MAVEN has made fundamental contributions to understanding the history of the Martian atmosphere and climate. «Read the rest of this article» Sections: Technology | No Comments
NASA has Two Heliophysics Missions that will Explore Sun, Earth’s Aurora
Understanding the physics that drive the solar wind and solar explosions – including solar flares and coronal mass ejections – could one day help scientists predict these events, which can impact human technology and explorers in space. ![]() From the International Space Station’s orbit 269 miles above the Indian Ocean southwest of Australia, this nighttime photograph captures the aurora australis, or “southern lights.” Russia’s Soyuz MS-12 crew ship is in the foreground and Progress 72 resupply ship in the background.

NASA reports ‘Great’ Conjunction of Jupiter, Saturn happens night of December 21st
In 1610, Italian astronomer Galileo Galilei pointed his telescope to the night sky, discovering the four moons of Jupiter – Io, Europa, Ganymede, and Callisto. In that same year, Galileo also discovered a strange oval surrounding Saturn, which later observations determined to be its rings. ![]() Saturn, top, and Jupiter, below, are seen after sunset from Shenandoah National Park, Sunday, Dec. 13, 2020, in Luray, Virginia. The two planets are drawing closer to each other in the sky as they head towards a “great conjunction” on December 21, where the two giant planets will appear a tenth of a degree apart.

NASA’s Infrared Telescope Facility data confirms 2020 SO to Be Upper Centaur Rocket Booster from 1960’s
The object, discovered in September by astronomers searching for near-Earth asteroids from the NASA-funded Pan-STARRS1 survey telescope on Maui, garnered interest in the planetary science community due to its size and unusual orbit and was studied by observatories around the world. ![]() In addition to supporting a variety of NASA planetary missions, NASA’s Infrared Telescope Facility on Maunakea on the Big Island of Hawaii is also used to determine the composition of near-Earth objects.

NASA simulates Rocket Launch for Artemis Moon Missions
There are many critical moments in a rocket’s journey from the ground to orbit, but perhaps none more so than the moment of ignition from the launch pad. When the Space Launch System, or SLS, rocket engines begin to roar – emitting fire, smoke, and shockwaves – it is critical the entire launch complex is designed to withstand the pressure. «Read the rest of this article» Sections: Technology | No Comments
NASA announces Sentinel-6 Michael Freilich Ready for Launch
“We’re almost there,” said project manager Parag Vaze of NASA’s Jet Propulsion Laboratory in Southern California. ![]() The Sentinel-6 Michael Freilich satellite is encapsulated in a protective nosecone, or payload fairing, at Vandenberg Air Force Base in California. The fairing will sit atop a SpaceX Falcon 9 rocket that will launch the satellite into Earth orbit in the late-November 2020.

NASA’s Mars Perseverance rover equipped with a Laser
Research with these Apollo-era lunar retroreflectors continues to this day, and scientists want to perform similar experiments on Mars. NASA’s Perseverance rover – scheduled to land on the Red Planet on February 18th, 2021 – carries the palm-size Laser Retroreflector Array (LaRA). ![]() Visible both in the inset photograph on the upper left and near the center of NASA’s Perseverance Mars rover in this illustration is the palm-size dome called the Laser Retroreflector Array (LaRA). In the distant future, laser-equipped Mars orbiters could use such a reflector for scientific studies. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s OSIRIS-REx spacecraft completes Second Rehearsal, Ready to make Sample Collection
The approximately four-hour “Matchpoint” rehearsal took the spacecraft through the first three of the sampling sequence’s four maneuvers: the orbit departure burn, the “Checkpoint” burn and the Matchpoint burn. «Read the rest of this article» Sections: Technology | No Comments
NASA reports Comet NEOWISE passes by the Sun, Providing a Treat for Observers
The comet cruised just inside Mercury’s orbit on July 3rd. This very close passage by the Sun is cooking the comet’s outermost layers, causing gas and dust to erupt off the icy surface and creating a large tail of debris. And yet the comet has managed to survive this intense roasting. ![]() Comet C/2020 F3 NEOWISE appears as a string of fuzzy red dots in this composite of several heat-sensitive infrared images taken by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission on March 27, 2020.

NASA’s TESS Satellite, Spitzer Space Telescope find Large World Orbiting Young Star
The system, known as AU Mic for short, provides a one-of-kind laboratory for studying how planets and their atmospheres form, evolve and interact with their stars. ![]() This image is an artist’s concept of the planet AU Mic b and its young parent star. The faint band of light encircling the pair is a disk of gas and dust from which both the star and the planet formed.
