    TOMEX+ Launch Update – Aug. 17

    The TOMEX+ sounding rocket mission is now targeting no earlier than Tuesday, Aug. 19, for the first launch attempt due to expected cloud cover in the area and down range camera sites. The mission needs clear skies in order to launch.

    NASA’s Arcstone Satellite and Instrument Fully Commissioned 

    An artist's rendering of NASA's Arcstone instrument on-orbit gathering measurements of lunar reflectance.

    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 […]

    NASA’s TOMEX+ Rocket to Track Turbulence at Edge of Space

    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 […]

    Giant Radar Antenna Reflector on NASA-ISRO Satellite in Full ‘Bloom’

    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 […]

    Seven Scientific Balloons to Fly From New Mexico for NASA Campaign

    A scientific balloon, capable of expanding to 11 million cubic feet at altitude, stands partially inflated against a clear blue sky. Ground crew in safety vests monitor the deployment while the translucent envelope is secured with tethers. Support vehicles including a semi-truck are positioned nearby, with orange safety cones marking the perimeter of the launch field

    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 […]

    NASA’s PREFIRE CubeSat Mission Extended

    This artist's concept depicts one of two PREFIRE CubeSats in orbit around Earth. The NASA mission will measure the amount of far-infrared radiation the planet's polar regions shed to space.

    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 […]

    Crew Sets Up Space Hardware to Make Fiber Optics and Brew Lunar Sake

    The International Space Station soars 259 miles above Cambodia in this long-duration photograph revealing star trails, lightning storms, and the city lights of Southeast Asia streaking below.

    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.

    Crew Tackles Cardiac Research, Cargo Ops, and Spacesuit Checks

    A vivid red and green aurora crowns Earth’s horizon over the southern Indian Ocean in this photo from the International Space Station as it orbited 270 miles above. At top left, a lit window reveals the docked SpaceX Dragon crew spacecraft docked to the orbital outpost's forward port on the Harmony module, set against a starry sky captured with long-exposure, low-light settings.

    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.
