Four astronauts will soon travel beyond low Earth orbit and fly around the Moon on Artemis II, a mission that will test NASA’s systems and hardware for human exploration of deep space. Since June 2023, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen have been preparing for their lunar journey. The approximately […]
Goldstone’s DSS-15 Antenna and the Milky Way
Deep Space Station 15, one of the 112-foot antennas at the Goldstone Deep Space Communications Complex near Barstow, California, looks skyward, with the stars of the Milky Way overhead, in September 2025. Goldstone is part of NASA’s Deep Space Network (DSN), which operates three complexes around the globe that support communications with dozens of deep […]
Artemis II Recovery Training
Off the coast of California, NASA’s Artemis Landing and Recovery team and the Department of War that will work together to retrieve the Artemis II crew and Orion spacecraft following their return to Earth and splashdown in the Pacific Ocean are performing a final simulation of their activities, called a just-in-time training, at sea on […]

U.S.-India NISAR Satellite Images Mississippi River Delta Region
Description The NISAR (NASA-ISRO Synthetic Aperture Radar) Earth-observing satellite’s L-band synthetic aperture radar (SAR) instrument captured this image of the Mississippi River Delta region in southeastern Louisiana on Nov. 29, 2025. The colors in the image represent varying types of cover, which tend to reflect microwaves from the radar differently. Portions of New Orleans appear […]
Resurrecting Ancient Enzymes in NASA’s Search for Life Beyond Earth
NASA-supported scientists have resurrected an enzyme first used by organisms on Earth 3.2-billion years ago and, in the process, have validated a chemical biosignature in rocks that is used to understand ancient life on Earth. The research provides a new understanding of what Earth’s biosphere was like early in our planet’s history and confirms a […]
Hubble Sees Galaxy with Dark Rings in New Light
This NASA/ESA Hubble Space Telescope image features an uncommon galaxy with a striking appearance. NGC 7722 is a lenticular galaxy located about 187 million light-years away in the constellation Pegasus. A lenticular, meaning “lens-shaped,” galaxy is a type whose classification sits between more familiar spiral galaxies and elliptical galaxies. It is also less common than spirals and ellipticals — partly because […]
