Humans in Space: Space Station Activities Leading Toward Future Lunar / Deep-Space Missions

As Tiangong Space Station heads into its 4th full year in space, the International Space Station will soon enter its 25th year of continuous human occupation in November. It is currently occupied by Expedition 71 and two members of Boeing Starliner CST-100. About 3,720 kilograms of food, scientific gear and other supplies recently arrived at the station via NG-21 dubbed S.S. Richard “Dick” Scobee, and the Progress MS-28 (89P) launch is scheduled for August 15 from Soyuz 2.1 in Baikonur Cosmodrome, Kazakhstan. The SpaceX Crew 9 mission with Zena Cardman, Nick Hague, Stephanie Wilson and Alexander Gorbunov will be postponed ‘significantly’ due to the continued delay of Sunita Williams and Butch Wilmore returning to Earth. The Boeing Starliner CST-100 is awaiting final confirmations to determine a date for undocking. At present, the planned end of the ISS may come around 2031 with the recent contract of the United States Deorbit Vehicle being won by SpaceX. Commercial space stations that are under development are Haven-1 (NET 2025), Axiom Space (first module Hab One may attach to ISS in 2026), Orbital Reef (2027) and Starlab (2028). Russia has indicated it may operate its own space station ~2027. India is planning Bharatiya Antariksha Station commencing 2028. Meanwhile humanity’s first outpost beyond LEO, Lunar Gateway, is underway for first module launches in 2028 to support Artemis 4 and future missions. (Image credits: NASA, CNSA, ESA)

SpaceX Works to Increase Starship Launches, Crucial for Artemis 3 Mission

The Federal Aviation Administration is holding public hearings for response to the SpaceX request to launch yearly up to 25 Starship / Super Heavy rockets from Boca Chica in Texas – “Starbase”. Four in-person meetings will be held August 13 and 15 in two Texas towns, and a virtual meeting will be held August 20. The Starship spacecraft and Super Heavy rocket (collectively “Starship”) are being designed / developed for taking up to 100 people and cargo to Earth orbit, the Moon and beyond. Some of the original visions for Starship included landing on an icy world in the Jovian system, and on Mars. The plan is for Starship and the SpaceX Human Landing System to be ready for Artemis 3 Human Moon Landing in 2026. Currently the 5th launch of Starship (NET August) is pending FAA approval. The plan is for its Super Heavy Booster to be caught after separation by the launch tower “chopstick” arms. June 6 was the 4th test flight of the 9-meter-diameter rocket. The 50-meter-tall Starship and 71-meter Super Heavy comprise the vehicle. The Starship will have 6 Raptor engines, which are reusable, methane-oxygen, staged-combustion with twice the thrust of the Falcon 9 Merlin engine, and three are Raptor Vacuum (RVac) engines for use in the vacuum of space. The Super Heavy will be powered by 33 Raptor engines, 13 in center and 20 around the aft perimeter. (Image credits: SpaceX)
