The Space Warfighting Analysis Center will brief industry representatives Oct. 27 on the results of its first “force design” study focused on space-based missile warning and missile tracking NATIONAL HARBOR, Md. — Chief of Space Operations Gen. John “Jay” Raymond said a new Space Force office called Space Warfighting Analysis Center (SWAC) will brief industry representatives

WAILEA, Hawaii — Diplomats and other experts see signs of progress at the United Nations on addressing space sustainability but caution it may will take many years before any sort of binding agreement emerges. In presentations at the Advanced Maui Optical and Space Surveillance Technologies, or AMOS, Conference here Sept. 17, officials said a United

KIHEI, Hawaii — A draft environmental assessment released by the Federal Aviation Administration suggests that SpaceX will be able to proceed with orbital Starship launches from Texas, but with a number of mitigations required. The release of the Draft Programmatic Environmental Assessment (PEA) by the FAA Sept. 17 starts a public comment period that will

WAILEA, Hawaii — The growing number of satellites in orbit is leading to calls to develop formal “right of way” rules, although there is no consensus on what those rules should be and how they should be established. Several close approaches of satellites in recent years, in some cases exacerbated by disagreements or communications breakdowns

KIHEI, Hawaii — SpaceX’s first private crewed mission ended with the splashdown of the Crew Dragon spacecraft off the Florida coast Sept. 18. The Crew Dragon spacecraft Resilience splashed down off the coast from Cape Canaveral, Florida, at 7:06 p.m. Eastern. The splashdown took place 50 minutes after the spacecraft started its deorbit burn. “Inspiration4,

WAILEA, Hawaii — The U.S. military will take space sustainability factors into account should it have to respond to an attack on its satellites, a Space Force official said Sept. 16. Speaking at the Advanced Maui Optical and Space Surveillance Technologies, or AMOS, Conference here, Col. Scott D. Brodeur, director of the National Space Defense

WAILEA, Hawaii — SpaceX’s first private Crew Dragon mission is set to end with a splashdown off the Florida coast Sept. 18, three days after liftoff from the Kennedy Space Center. At the end of a live video session with the four-person Inspiration4 mission Sept. 17, SpaceX said they were planning a splashdown at 7:06

TAMPA, Fla. — CesiumAstro expects to be building satellites mostly by itself in two years to house the active phased arrays it has been developing, aiming to shift the paradigm for electronically steered antennas with commercial-like industrialization processes that lower costs and speed up production. Austin, Texas-based CesiumAstro bought parts from small satellite manufacturers for

WAILEA, Hawaii — Two years after the close approach of a Starlink satellite with a European Space Agency satellite alarmed some in the space industry, SpaceX says it’s working closely with a wide range of satellite operators to ensure safe space operations. In September 2019, ESA announced it maneuvered an Earth science satellite called Aeolus

KIHEI, Hawaii — Small launch vehicle developer ABL Space Systems has won a contract to launch a NASA technology demonstration spacecraft in 2023. ABL Space Systems said Sept. 16 it will launch the NASA Cryogenic Demonstration Mission spacecraft on its RS1 rocket in 2023. NASA selected a team led by Lockheed Martin in 2020 to
