Topic: Huntsville AL
While the mission team plans to continue collecting data well into 2022, the increasing dustiness of the spacecraft’s solar panels and the onset of the Martian winter led to a decision to conserve power and temporarily limit the operation of its instruments. ![]() This artist’s concept depicts NASA’s InSight lander after it has deployed its instruments on the Martian surface.

Two NASA Technologies that will aid Perseverance Rover’s Mars LandingHow two new technologies will help Perseverance, NASA’s most sophisticated rover yet, touch down onto the surface of Mars this month.
But the very features that make the site fascinating to scientists also make it a relatively dangerous place to land – a challenge that has motivated rigorous testing here on Earth for the lander vision system (LVS) that the rover will count on to safely touch down. «Read the rest of this article» Sections: Technology | No Comments
NASA to proceed with Green Run Hot Fire of Space Launch System Rocket
NASA conducted the seventh test of the SLS core stage Green Run test series – the wet dress rehearsal – on December 20th at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and marked the first time cryogenic, or super cold, liquid propellant was fully loaded into, and drained from, the SLS core stage’s two immense tanks. ![]() Fully loading the propellant and detecting no leaks is a major milestone for the Green Run test series. A total of 114 tanker trucks delivered propellant to six propellant barges next to the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The barges deliver more than 733,000 gallons of liquid hydrogen and liquid oxygen to the core stage for NASA’s Space Launch System (SLS) rocket as part of the seventh test in the Green Run test series.

Marsha Blackburn announces Space Command to be located in Tennessee Valley
“The new Space Command Center in the Tennessee Valley is an important investment in both the future of our military and in the skilled workforce of the region,” said Senator Blackburn. “This base will bring over 1,600 new jobs in the area and more as the command grows.” «Read the rest of this article» Sections: Politics | No Comments
NASA ends mission for Insight Lander’s Heat Probe
Since February 28th, 2019, the probe, called the “mole,” has been attempting to burrow into the Martian surface to take the planet’s internal temperature, providing details about the interior heat engine that drives Mars’ evolution and geology. But the soil’s unexpected tendency to clump deprived the spike-like mole of the friction it needs to hammer itself to a sufficient depth. ![]() In this artist’s concept of NASA’s InSight lander on Mars, layers of the planet’s subsurface can be seen below, and dust devils can be seen in the background.

NASA’s Juno Spacecraft gets Mission Extended
This expansion tasks Juno with becoming an explorer of the full Jovian system – Jupiter and its rings and moons – with multiple rendezvous planned for three of Jupiter’s most intriguing Galilean moons: Ganymede, Europa, and Io. ![]() This view of Jupiter’s atmosphere from NASA’s Juno spacecraft includes something remarkable, two storms caught in the act of merging.

NASA reports 3D Printed Rocket Engine Parts make it through 23 Hot-Fire Tests
Through a series of hot-fire tests in November, NASA demonstrated that two additively manufactured engine components – a copper alloy combustion chamber and nozzle made of high-strength hydrogen resistant alloy – could withstand the same extreme combustion environments that traditionally manufactured metal structures experience in flight. ![]() Hot-fire testing of an additively manufactured copper alloy combustion chamber and a nozzle made of a high-strength hydrogen resistant alloy.

NASA lists 3 Things learned from Mars InSight Mission
A little more than one Martian year later, the stationary lander has detected more than 480 quakes and collected the most comprehensive weather data of any surface mission sent to Mars. InSight’s probe, which has struggled to dig underground to take the planet’s temperature, has made progress, too. There was a time when the surfaces of Mars and Earth were very similar. Both were warm, wet, and shrouded in thick atmospheres. ![]() Clouds drift over the dome-covered seismometer, known as SEIS, belonging to NASA’s InSight lander, on Mars.
