Commissioning has been completed for NASA’s Arcstone instrument and the bus. Themain structure of the satellite, or bus, and instrument testing began shortly after launching from Vandenberg Space Force Base in California July 23 on a SpaceX Transporter-14 rideshare mission.   On Aug. 13, the Arcstone spectrometer, the first instrument dedicated to improving the accuracy of […]

The Turbulent Oxygen Mixing Experiment Plus, or TOMEX+, is a NASA sounding rocket mission that will investigate one of Earth’s most turbulent atmospheric regions — the mesopause. Led by principal investigator Jim Clemmons, a professor of physics and astronomy at the University of New Hampshire, TOMEX+ will open its launch window from NASA’s Wallops Flight […]

Seventeen days after NISAR’s launch from southeastern India, an essential piece of science hardware has unfurled in orbit. Spanning 39 feet (12 meters), the drum-shaped antenna reflector on the NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission from NASA and the Indian Space Research Organisation (ISRO) successfully unfurled in low Earth orbit. The reflector had been […]

A NASA Scientific Balloon Program annual campaign is taking flight at the agency’s balloon launch facility in Fort Sumner, New Mexico. Seven balloon flights carrying scientific experiments and technology demonstrations are scheduled to launch starting in mid-August. To follow the missions in the 2025 Fort Sumner campaign, visit NASA’s Columbia Scientific Balloon Facility website for real-time updates […]

The twin cube satellites will operate through at least September 2026, expanding focus from the poles to the whole planet to improve modelling and weather forecasts. NASA’s PREFIRE (Polar Radiant Energy in the Far-InfraRed Experiment) mission has been extended through September 2026 and is broadening its focus from Earth’s poles to the entire globe. The […]

Fiber manufacturing and lunar brewing wrapped up the research week aboard the International Space Station helping NASA and its international partners promote the commercialization of space. The Expedition 73 crew also continued its space biology studies to keep astronauts healthy while packing a resupply ship for its upcoming departure and maintaining life support systems.

Expedition 73 continued exploring how microgravity affects blood flow to help doctors protect crews staying longer in space and traveling farther away from Earth. The International Space Station residents also kept up preparations for an upcoming U.S. cargo mission while maintaining orbital lab systems.

Before NASA’s Artemis II test flight launches a crew of four astronauts around the Moon and back, astronauts and teams on the ground at NASA’s Kennedy Space Center in Florida, are training for different scenarios that could take place on launch day. On Aug. 11 and 12, teams with the agency’s Exploration Ground Systems Program […]

Heart and blood pressure studies led the research schedule for the Expedition 73 crew on Wednesday informing scientists how the cardiovascular system adapts to weightlessness. The International Space Station residents are also gearing up for the next SpaceX Dragon cargo mission and cleaning spacesuits for potential spacewalks later this year.
