Launch of NASA’s SpaceX Crew-5 mission to the International Space Station has been delayed by nearly a month because the Falcon 9 booster was damaged during transport. The Crew-5 mission — the fifth of NASA’s Commercial Crew Program — will now launch no earlier than September 29. The launch was supposed to start in early September, meaning the mission has been delayed by nearly a month. The revised schedule will allow SpaceX to “complete hardware processing,” according to a NASA statement. SpaceX is preparing a Falcon 9 booster for its maiden voyage, but obstacles along the way have resulted in some extra work and scheduling changes, as NASA explains: SpaceX removed and replaced the rocket interstage and some onboard instrumentation after hardware was damaged during transportation from SpaceX’s production plant in Hawthorne, California, to the company’s McGregor test facility in Texas for stage testing. The SpaceX team completed – and the NASA team...

Summary: Researchers reveal how astronauts can avoid the neuromuscular problems that occur as a result of extended space travel. Source: Doshisha University Among the many functions performed by skeletal muscles, one of them is maintaining our posture. If it weren’t for these muscles, the gravitational pull of the earth might make it difficult for us to get up and walk. The group of muscles—mostly in our legs, back and neck—that are responsible for maintaining posture and allowing us to move against the force of gravity are called ‘anti-gravity’ muscles. But what happens to these muscles when there is no gravity (or “unloading” force of gravity) to counteract them? That question may sound silly to some, but not to an astronaut on the International Space Station (ISS)! In space, where gravity is minimal, our muscles (especially anti-gravity ones) are not used much, which can lead to atrophy and changes in their structure and properties. In fact, human ca...
