Two astronauts are one step closer to returning to Earth. A SpaceX Dragon carrying a crew of four will dock at the International Space Station later tonight. The crew will replace Butch Wilmore and Suni Williams, who have been in space for more than nine months.

NASA astronauts Sunita Williams and Barry "Butch" Wilmore are scheduled to return to Earth after an extended nine-month mission aboard the International Space Station (ISS). Their return was delayed due to propulsion issues with Boeing's Starliner spacecraft.

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).
