NASA astronauts Butch Wilmore and Sunita Williams are preparing for their return to Earth after spending over nine months aboard the International Space Station (ISS). The duo are set to return to Earth on Tuesday evening a day earlier than the previously reported schedule,

Several reports showed that both the astronauts are GS-15 federal employees whose annual salary ranges from $125,133 to $162,672 (approx Rs 1.08 crore to Rs 1.41 crore).

Sunita Williams, who was supposed to return in a week when she went on Boeing’s first astronaut flight to ISS last year, hit the 9-month mark this month.
