A SpaceX rocket sent to retrieve two astronauts who have been stranded in space for nine months has finally docked at the International Space Station.

The SpaceX Falcon 9 rocket successfully took off Friday night from NASA’s Kennedy Space Center, on a mission to deliver four new astronauts to the satellite.

The arrival of the new crew means that Sunita Williams and Butch Wilmore will finally be able to return to Earth following months in limbo.

The pair have been stranded in orbit since June 5, with SpaceX owner Elon Musk and others claiming Williams and Wilmore were left on the ISS for political reasons although this has been refuted by the astronauts.

The arrival of Crew-10, which includes NASA astronauts Anne McClain and Nichole Ayers, Japan’s Takuya Onishi, and Russia’s Kirill Pesko, means they will be allowed to return home.

The new crew docked at the ISS just after 12:04am ET on Sunday after a more than 28 hour journey.

Wilmore was scheduled to open the hatch after carrying out pressurizing and leak check procedures.

It is hoped that Williams and Wilmore will be able to begin their return to Earth aboard the SpaceX Dragon Capsule as early as Wednesday. The duo were initially scheduled for an eight day mission.

NASA ‘s beleaguered mission to rescue two stranded astronauts finally successfully launched on Friday

Butch Wilmore and Sunita Williams were original scheduled for an eight-day mission, but were forced to stay after technical issues plagued the Boeing’s Starliner that brought them to the ISS

They will be joined on their return flight by NASA’s Nick Hague and Russia’s Aleksandr Gorbunov. 

The four newcomers will spend the next few days learning the station’s ins and outs 

The new crew will spend the next six months at the space station, considered the normal stint. 

Their arrival comes after several setbacks for the relief mission, the  most recent of which saw the flight scrapped at the eleventh hour on Wednesday due to a hydraulic system issue with the Falcon 9 rocket.

NASA had moved up the return mission by two weeks after after President Trump told Musk to ‘go get’ Williams and Wilmore.

Before the president’s request, the astronauts were not coming back earlier than March 26.

‘It’s been a roller coaster for them, probably a little bit more so than for us,’ Williams said of her family.

The mission became a flashpoint during the election after Trump and Musk claimed the astronauts had been left languishing in space for political reasons.

Musk said he offered to bring the astronauts home eight months ago, but the Biden Administration shot it down because it would’ve made Trump ‘look good’ in the presidential race against former vice president Kamala Harris.

During a recent press briefing, Ken Bowersox, associate administrator of the NASA’s Space Operations Mission Directorate, admitted that there ‘may have been conversations’ in the Biden White House about delaying the return for political optics of having Trump’s most famous donor save the day, but he was not part of the discussions.

The Crew-10 launch occurred as Wilmore and Williams were asleep in their daily schedule on the station, Dina Contellam deputy manager of NASA’s ISS program, told reporters after the launch. 

Having seen their mission turn into a normal NASA rotation to the ISS, Wilmore and Williams have been doing scientific research and conducting routine maintenance with the other five astronauts.

Williams told reporters earlier this month that she was looking forward to returning home to see her two dogs and family including her husband Michael and mom Bonnie.

Wilmore has two teenage daughters who he shares with wife Deanna.

‘We’ve had so many changes and it’s a bit mentally exhausting,’ his daughter Daryn told E! News about the ongoing saga.
