NASA and Northrop Grumman are preparing to send the company’s next cargo mission to the International Space Station, flying research to support Artemis missions to the Moon and human exploration of Mars and beyond, while improving life on Earth. SpaceX’s Falcon 9 rocket will launch Northrop Grumman’s 23rd commercial resupply services mission to the orbiting laboratory. The investigations aboard the Cygnus spacecraft aim to refine semiconductor crystals for next-generation technologies, reduce harmful microbes, improve medication production, and manage fuel pressure. NASA, Northrop Grumman, and SpaceX are targeting launch in mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Read about some of the investigations traveling to the space station: Res...

SpaceX’s Starship rocket is pictured at sunset at Starbase, Texas, following a mission scrub for Flight 10 on Monday, Aug. 25, 2025. Image: SpaceX SpaceX is hoping that with two successive days of scrubs behind it, it will be able to launch its massive Starship rocket on its third launch attempt on Tuesday evening. It’s first launch attempt on Sunday was prevented when an issue with the liquid oxygen ground systems connected to the upper stage caused a scrub about 40 minutes before flight. Then on Monday, anvil clouds in the vicinity of the pad prevented a launch about halfway through SpaceX’s available hour-long window. SpaceX is targeting liftoff at the opening of the window on Tuesday, which begins at 6:30 p.m. CDT (7:30 p.m. EDT / 2330 UTC). Spaceflight Now will have live coverage begi...

NASA will hold a media teleconference at 12 p.m. EDT on Thursday, Sept. 4, to discuss the agency’s upcoming Sun and space weather missions, IMAP (Interstellar Mapping and Acceleration Probe) and Carruthers Geocorona Observatory. The two missions are targeting launch on the same rocket no earlier than Tuesday, Sept. 23. The IMAP mission will map the boundaries of our heliosphere, the vast bubble created by the Sun’s wind that encapsulates our entire solar system. As a modern-day celestial cartographer, IMAP will explore how the heliosphere interacts with interstellar space, as well as chart the range of particles that fill the space between the planets. The IMAP mission also will support near real-time observations of the solar wind and energetic particles. These energetic particles can pr...
