New Ideas to Reduce Muscle Loss During Spaceflight

One of the obstacles to long space missions is the muscle loss that astronauts suffer from. It’s called atrophy, and NASA says that astronauts can lose up to 20% muscle mass during missions of only 5 to 11 days. This muscle loss affects what are called “anti-gravity muscles,” including calf muscles, the quadriceps and the muscles of the back and neck.

This muscle loss makes it hard for astronauts to complete their tasks, especially when missions to Mars happen. It can also be very dangerous to astronauts, because they’re weakened when they return to Earth. If there are problems during re-entry, and they need to perform any strenuous emergency procedures, that missing muscle could be the difference between life and death.

Europe is Working On a Reusable Space Transport System: Space Rider

The ESA is developing its own spacecraft capable of re-entry into Earth’s atmosphere. The reusable spacecraft is called the Space RIDER (Reusable Integrated Demonstrator for Europe Return), and the ESA says that the Space Rider will be ready for launch by 2022. It’s being designed to launch on the Vega-C rocket from Europe’s spaceport in Kourou, French Guiana.

Beresheet Crashed.

The Israeli Beresheet spacecraft has crashed into the Moon. The craft, whose name is Hebrew for “in the beginning” made its descent to the Moon but failed to stick its landing. If it had been successful, it would have put Israel in elite company, and made them only the fourth country to have a soft landing on the Moon, joining the USA, China, and the former Soviet Union.

The long-anticipated first flight of the SpaceX Crew Dragon is almost here. Early in January, the Crew Dragon was rolled out of its hangar at Kennedy Space Center, and on January 24th it performed a brief static firing as part of its testing. The Crew Dragon’s inaugural flight, called Demo-1, is not far off.

Neither NASA nor SpaceX has given us a date for Demo-1, but we’re getting close.

In an announcement sure to make you quiver with delight, Elon Musk says that SpaceX could begin short-hop test flights of its Starship prototype as early as next Spring. The Starship, which looks like something from a 1950’s sci-fi novel cover (awesome!) is intended to carry people to the Moon and Mars. When the spacecraft design was originally announced in 2016, it was called the Mars Colonial Transporter, and it sent shockwaves through the community.

Now, it’s almost test-flight time.
