Live coverage: SpaceX to launch Starship Flight 8 suborbital test mission from Starbase
- SpaceX is preparing for the launch of Starship Flight 8 suborbital test mission from Starbase in Texas on March 3.
- The mission aims to achieve goals from the previous Flight 7 test, involving a series of demonstrations with Starship.
- The mission includes the launch of Super Heavy booster B15 and Ship upper stage S34 for the second time.
- The plan involves demonstrations like engine relight in space, satellite deployment, and a propulsive splashdown in the Indian Ocean.
- Booster 15 will try to return to its launch site for the third catch out of four opportunities using 'Mechazilla' arms.
- SpaceX has made procedural changes for this mission, adjusting fueling and launch timelines from the previous test.
- Flight 8 will focus on objectives not achieved in Flight 7, including payload deployment and reentry experiments.
- SpaceX aims to deploy four Starlink simulators, less than Flight 7's 10, with plans for safe atmospheric burn-up into the Indian Ocean.
- SpaceX has addressed issues from Flight 7, including fire prevention in Starship's attic and Raptor engine upgrades for the upcoming flight.
- Elon Musk suggested the need for ship reentry perfection before attempting ship catches, while targeting reusability for both Ship and booster in the future.

The ISS’s Sterile Environment Could Be Making Astronauts Sick
- Living in space presents challenges, including the microbial environment inside spacecraft like the ISS.
- The ISS is a highly controlled, enclosed environment with reduced microbial diversity, affecting astronaut health.
- A study analyzed the ISS's microbial landscape, highlighting potential health risks for astronauts on long-term missions.
- The study mapped the microbiome of the ISS, showing human-associated bacteria dominate the station.
- ISS microbial diversity is lower than most built environments on Earth, potentially impacting astronauts' immune systems.
- While reducing harmful bacteria is crucial, the absence of beneficial microbes in space poses health risks.
- Astronauts in space report rashes, allergies, immune dysfunction, and increased infection risk due to limited microbial exposure.
- Maintaining a diverse microbial environment in space is proposed to mimic Earth's natural exposures and promote astronaut health.
- NASA aims to improve microbial management in space, using advanced methods like metagenomics for real-time analysis.
- Future space habitats must balance sanitation with beneficial microbial diversity to support astronaut well-being on long missions.
