Crossing Maine’s Waters in Pursuit of GNATS


The Gulf of Maine North Atlantic Time Series, or GNATS, produces data that is used to validate NASA’s suite of ocean color satellites.

Spacewalk preparations are ongoing aboard the International Space Station as two astronauts gear up to replace a high-speed antenna next week. The Expedition 75 crew members also practiced their emergency response skills in coordination with mission controllers on Earth.

Katalyst Space uploaded a flight software update that reestablished attitude control of its LINK spacecraft, which is set to boost NASA’s Swift observatory.

Vein scans and spacesuit checks were the top duties for the Expediton75 crew aboard the International Space Station on Tuesday. The orbital residents also continued their Earth photography sessions, cargo operations, and life support maintenance.

The next spacewalk outside the International Space Station is set to take place on Tuesday, Aug. 18. Two Expedition 75 astronauts will work in the vacuum of space to replace a space-to-ground antenna to maintain high-speed data and communication transmissions between the orbital outpost and mission controllers.
The most common misconception about sonic booms is that they’re just the sound created at the moment when an aircraft “breaks the sound barrier.” In reality, a sonic boom is continuous, the audible evidence of invisible pressure waves forming as an aircraft travels faster than sound. As these waves travel toward the ground, they can merge, creating an explosive bang heard by everyone the aircraft passes over. Sonic booms have been a problem since aircraft first began exceeding the speed of sound, or Mach 1, so disturbing to people below that for decades U.S. and international regulations banned commercial supersonic flight over […]

On Aug. 6, NASA astronauts Jessica Meir and Anil Menon concluded a 6-hour, 27-minute spacewalk outside the International Space Station. Meir and Menon successfully completed their primary objective of preparing the 3B power channel for the future installation of a roll out solar array. Toward the end of the spacewalk, a carbon dioxide sensor on Menon’s spacesuit indicated an unexpected data reading. Menon reported no other issues during the spacewalk.

Science data from NASA’s IMAP (Interstellar Mapping and Acceleration Probe) mission is now available. After its successful launch on Sept. 24, 2025, IMAP’s prime mission began a few months later, on Feb. 1. All 10 instruments on IMAP have been successfully collecting data. While data from three of the instruments are not yet ready for […]

NASA astronauts Jessica Meir and Anil Menon concluded their spacewalk outside the International Space Station at 3 p.m. EDT. It was Menon’s first spacewalk and Meir’s sixth.

When the trio of NASA’s SkyFall helicopters takes to the Martian skies, one of their tasks will be to hunt for frozen water — a critical resource for future astronauts — using ground-penetrating radar. For that radar to work, each rotorcraft will carry a flexible, fabric-based antenna that will need to extend below the aircraft […]
