Astronauts to use diapers amid malfunctioned toilet on their journey back to Earth

New Delhi : Four astronauts, who are scheduled to return to Earth on Monday, are left with no option but to use diapers on their journey as the toilet on SpaceX capsule is reportedly not working.

Describing the situation as "suboptimal" but manageable, NASA astronaut Megan McArthur said in a news conference from orbit, "Spaceflight is full of lots of little challenges. This is just one more that we’ll encounter and take care of in our mission. So, we’re not too worried about it."

During their return journey, the crew members will have to spend around 20 hours in the SpaceX Capsule.

Before launching replacements, the mission managers decided to bring McArthur and the rest of her crew home after a series of meetings on Friday.   

It has been over a week since when the return of astronauts is being delayed due to bad weather conditions and on Monday there is a window to make it happen.

The company is now looking for lift-off for Wednesday night at the earliest. French astronaut Thomas Pesquet, who will return with McArthur, said that last six months had been intense.
