Exploring the heart of space weather with the Geospace Dynamics Constellation
Sunday, 05 December 2021 01:06
The Geospace Dynamics Constellation mission - or GDC - is a team of satellites that will study Earth's upper atmosphere and provide the first direct global measurements of our planet's dynamic and complex interface with the space environment. This boundary between Earth's atmosphere and space is called the ionosphere-thermosphere (I-T) system.

Two NASA astronauts have completed the 13th spacewalk at the International Space Station (ISS) this year, the agency said, days after the event was postponed over a debris risk.
Astronauts Thomas Marshburn and Kayla Barron headed outside the space laboratory on Thursday, replacing a faulty antenna and restoring its capability.
"It was awesome!" Barron said after completing her first spac NASA awards Artemis contract for future SLS boosters
Sunday, 05 December 2021 01:06
NASA has awarded the Booster Production and Operations Contract (BPOC) to Northrop Grumman of Brigham City, Utah, to build boosters for the agency's Space Launch System (SLS) rocket to support nine SLS flights. Northrop Grumman, the lead booster contractor, has produced booster motors for the first three Artemis missions and is casting the motors for the fourth lunar mission.

With Flight 17, Ingenuity continues its journey back to Wright Brothers Field at the Octavia E. Butler landing site. Flight 17 is the third flight of this journey and is scheduled to take place no earlier than Sunday, Dec. 5 with the data arriving back on Earth no earlier than later that same day.
Flight 17 is approximately half of Flight 9 in reverse, which was one of the most challenging High-Speed Lunar Surface Transportation

Proposed lunar surface mobility systems for human colonization appear to be severely limited in speed and payload capabilities. Roving vehicles are massive and move slowly over the rough lunar terrain, at a high cost of energy and life support supplies.
Flying units, powered by chemical rockets are fast, but the price of speed is payload and range. On the other hand, a hopping transporter Lunar radar data uncovers new clues about moon's ancient past

The dusty surface of the moon - immortalized in images of Apollo astronauts' lunar footprints - formed as the result of asteroid impacts and the harsh environment of space breaking down rock over millions of years. An ancient layer of this material, covered by periodic lava flows and now buried under the lunar surface, could provide new insight into the Moon's deep past, according to a team of s TESS discovers a planet the size of Mars but with the makeup of Mercury

Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit - and a single, scorching year - in less than 24 hours. How these planets came to be in such extreme configurations is one of the continuing mysteries of exoplanetary science.
Now, astronomers have discovered an ultra-short-period planet (USP) that is also super light. The India’s Chandrayaan-2 maneuvered to avoid close approach to NASA’s Lunar Reconnaissance Orbiter

India’s Chandrayaan-2 lunar orbiter maneuvered in October to avoid a close approach to NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft, a conjunction both agencies have acknowledged but have said little more about.
Total solar eclipse plunges Antarctica into darkness
Saturday, 04 December 2021 18:42
A total solar eclipse plunged Antarctica from summer into darkness early Saturday in a rare astronomical spectacle witnessed by a handful of scientists and thrill-seekers—and countless penguins.
"The visibility was excellent," said Raul Cordero of the University of Santiago de Chile (USACH), who was on site to witness "totality" at 0746 GMT, with the "ring of fire" phase lasting just over 40 seconds.
Solar eclipses occur when the Moon passes between the Sun and Earth, casting its shadow on Earth. For the eclipse to be total, the Sun, Moon and Earth must be directly aligned.
Totality was visible only in Antarctica, experienced by a small number of scientists, experts and adventure tourists—who paid some $40,000 for the privilege.
Streamed live by NASA from the Union Glacier camp in Antarctica, the eclipse began at 0700 GMT as the Moon began to move in front of the Sun, coming to an end at 0806 GMT.
The Union Glacier camp is situated about 1,000 kilometers (600 miles) north of the South Pole.
