The orbiter, which takes its name from Arthur C. Clarke’s classic sci-fi novel “2001: A Space Odyssey” (Clarke blessed its use before launch), was sent to map the composition of the Martian surface, providing a window to the past so scientists could piece together how the planet evolved. ![]() NASA’s Mars Odyssey spacecraft passes above Mars’ south pole in this artist’s concept. The spacecraft has been orbiting Mars since October 24th, 2001. (Image credit: NASA/JPL) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Spitzer Space Telescope data reveals three fastest-spinning Brown Dwarfs ever discovered
In a study appearing in the Astronomical Journal, the team that made the new speed measurements argue that these three rapid rotators could be approaching a spin speed limit for all brown dwarfs, beyond which they would break apart. ![]() The faster a brown dwarf spins, the narrower the different-colored atmospheric bands on it likely become, as shown in this illustration. Some brown dwarfs glow in visible light, but they are typically brightest in infrared wavelengths, which are longer than what human eyes can see.

NASA’s Ingenuity Mars Helicopter set to take Flight, Sunday
If all proceeds as planned, the 4-pound (1.8-kg) rotorcraft is expected to take off from Mars’ Jezero Crater Sunday, April 11th, at 12:30pm local Mars solar time (9:54pm CDT, 7:54pm PDT), hovering 10 feet (3 meters) above the surface for up to 30 seconds. ![]() NASA’s Ingenuity helicopter unlocked its blades, allowing them to spin freely, on April 7th, 2021, the 47th Martian day, or sol, of the mission. This image was captured by the Mastcam-Z imager aboard NASA’s Perseverance Mars rover on the following sol, April 8th, 2021.

NASA’s Perseverance Rover sends First Weather Report from Mars
The Mars Environmental Dynamics Analyzer (MEDA) system aboard NASA’s Perseverance rover first powered on for 30 minutes on February 19th, approximately one day after the rover touched down on the Red Planet. Around 8:25pm PST that same day, engineers received initial data from MEDA. ![]() Wind sensors that are part of the MEDA instrument suite can be seen deployed from the mast of NASA’s Perseverance Mars rover in this image taken before the rover was launched.

NASA’s Mars Perseverance Rover takes photo with Ingenuity Helicopter
Perseverance captured the image using a camera called WATSON (Wide Angle Topographic Sensor for Operations and eNgineering), part of the SHERLOC (Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals) instrument, located at the end of the rover’s robotic arm. ![]() NASA’s Perseverance Mars rover took a selfie with the Ingenuity helicopter, seen here about 13 feet (3.9 meters) from the rover. This image was taken by the WASTON camera on the rover’s robotic arm on April 6, 2021, the 46th Martian day, or sol, of the mission.

NASA’s Mars Curiosity Rover Team names Mountain after Rafael Navarro-González
The inspiration for the name is award-winning scientist Rafael Navarro-González; he died on January 28th, 2021, from complications related to COVID-19 Coronavirus. ![]() NASA’s Curiosity Mars rover used its Mastcam to take an image of this mountain, nicknamed “Rafael Navarro Mountain” after the astrobiologist Rafael Navarro-González, who worked on the mission until he passed away January 26th, 2021.

NASA’s Ingenuity Mars Helicopter makes it through First Night on Mars
Evening temperatures at Jezero Crater can plunge as low as minus 130 degrees Fahrenheit (minus 90 degrees Celsius), which can freeze and crack unprotected electrical components and damage the onboard batteries required for flight. Surviving that first night after being deployed from where it was attached to the belly of NASA’s Perseverance rover on April 3rd is a major milestone for the 4-pound (1.8 kilograms) rotorcraft. ![]() NASA’s Ingenuity helicopter can be seen on Mars as viewed by the Perseverance rover’s rear Hazard Camera on April 4th, 2021, the 44th Martian day, or sol of the mission.

NASA’s Psyche Spacecraft final assembly underway
Over the next year, the spacecraft will finish assembly and undergo rigorous checkout and testing before it’s shipped to Cape Canaveral, Florida, for an August 2022 launch to the main asteroid belt. The Solar Electric Propulsion (SEP) Chassis, crafted by Maxar Technologies’ team in Palo Alto, California, is the size of a van and represents more than 80% (by mass) of the hardware that will ultimately make up the Psyche spacecraft. ![]() In late March of 2021, a main component of NASA’s Psyche spacecraft was delivered to JPL, where assembly, test, and launch operations are underway.

NASA collects data on Mars Landing from spacecraft’s heat shield
NASA’s Perseverance rover successfully landed on February 18th, 2021, beginning its robotic exploration of the Red Planet. MEDLI2 was one of the crucial technologies on the rover’s protective aeroshell that helped document the entry, descent, and landing (EDL) of the spacecraft. All of the MEDLI2 data was stored on Perseverance for transmission to Earth after a successful landing. ![]() The Mars 2020 spacecraft’s heat shield falls away as the aeroshell descends to Mars on Feb. 18, 2021. The orange cabling seen on the shield is part of a suite of sensors and electronics called MEDLI2, which collects data during the descent that will help engineers land future spacecraft on Mars.
