The crew-1 mission launched by SpaceX . Hence Option 2 is Correct . The mission is part of NASA’s Commercial Crew Program, whose objective is to make access to space easier in terms of its cost. This will carry four astronauts on NASA missions, maintaining a space station crew of seven to maximize time dedicated to scientific research on the orbiting laboratory. With this, the cargo and crew can be easily transported to. The members of the crew will conduct microgravity studies and deliver new science hardware to ISS . Once in orbit, NASA astronauts will collect samples to provide data to scientists back on Earth so that they can continue to study how dietary changes affect his body . The crew will also study the effects of dietary improvements on immune function and the gut microbiome and how those improvements can help crews adapt to spaceflight.
