The astronauts’ main mission, identified as Demo-2, is a closing check of the Crew Dragon’s performance before NASA certifies it for ISS crewed transportation missions. Nonetheless, NASA made a decision to prolong their keep so that Cassidy would not be the lone US astronaut aboard the ISS.
“The SpaceX crew, with Chris Cassidy previously on-board the Intercontinental House Station, will be executing experiments on physiology, cardiovascular experiments, bodily and daily life sciences, screening out everyday living assistance techniques … and testing out habitation experiments for our potential human room exploration,” NASA’s Kirk Shireman explained final month. Behnken could possibly also guide Cassidy on a spacewalk to replace batteries on the ISS’s photo voltaic ability trusses.
The astronauts are envisioned to keep on being on the ISS from a person to a few months, “based on the readiness of the up coming professional crew launch,” NASA explained earlier in Might. The most stay will be will be 110 days because of to fears about how the Crew Dragon’s solar panels will hold up in the complicated situations of place.
Crew Dragon’s mission will only be full at the time the astronaut’s properly arrive back again on Earth. That reentry is predicted to be a particularly tense section of the mission, irrespective of substantial screening by SpaceX. “I consider it was an argument that the return is more unsafe in some means than the ascent, so in buy to declare victory but, we have to have to carry them dwelling safely and securely [and] make sure that we’re accomplishing every thing we can to decrease that possibility of reentry and return,” Musk said.
