SpaceX's Dragon spacecraft was launched on Wednesday on a way to bring worms, liquid fuel and other new experiments to the International Space Station.
The spacecraft, riding on a Falcon1 9 rocket, lifted off at 1:16 p.m. EST at the Launch Complex 40 at Cape2 Canaveral Air Force Station in Florida. It is the sixth resupply mission to the space station this year.
About 10 minutes after the launch, the spacecraft reached its preliminary orbit, then deployed3 its solar arrays, starting multiple thruster firings to reach the space station.
The spacecraft, which flew to the space station in February of 2017, is carrying 36,000 roundworms in pouches4 to the orbiting lab and and if goes well, about two or three million ones will come back to earth. It is part of a study that may offer a better understanding of why muscles deteriorate5 in microgravity.
"They're a great model for using to study human changes, even though they're just a 1-mm-long worm," said Timothy Etheridge, the principal investigator6 of the mission. "Their muscles are both structurally7 and functionally8 extremely similar to people, so even more so when we're talking about understanding muscle changes, worms are a very good model."
The findings can improve methods to help astronauts maintain their strength during future space travel and also lead to new treatments for the elderly who chronically9 suffer from muscle loss.
