The four Crew-6 astronauts will now depart the International Space Station on Sept. 3, 24 hours later than planned.

Four astronauts on the International Space Station now have to wait at least one more day to return to Earth after bad weather delayed their SpaceX capsule's return. 

SpaceX and NASA announced Friday (Sept. 1) that the Crew Dragon capsule carrying their Crew-6 astronauts will now depart the International Space Station(ISS) no earlier than early Sunday (Sept. 3), a 24-hour delay that pushes the crew's splashdown to just after midnight Monday morning. The Crew-6 astronauts were originally slated to undock on Saturday and land the next day.

"NASA and SpaceX are standing down from the Saturday, Sept. 2, departure opportunities for the agency's Crew-6 mission from the International Space Station due to unfavorable weather conditions near the splashdown sites off the coast of Florida," NASA officials wrote in an update Friday morning (Sept. 1). 

The Crew-6 Dragon capsule is now scheduled to undock from the ISS on Sunday at 7:05 a.m. EDT (1105 GMT), with splashdown to follow on Monday at 12:07 a.m. EDT (0407 GMT). But that schedule depends on local weather conditions at the Crew-6 Dragon's splashdown sites, NASA officials said. 

"Mission teams will meet Friday evening to determine the viability of the next Crew-6 undock target," the wrote in the update. "The Dragon spacecraft, named Endeavour, remains healthy while currently docked to the space station as Crew-6 prepares for their return trip to Earth completing a nearly six-month science mission in orbit."

The four astronauts returning to Earth on Crew-6 are NASA astronauts Stephen Bowen and Warren "Woody" Hoburg, the United Arab Emirates' Sultan Al Neyadiand Andrey Fedyaev of Russia's space agency, Roscosmos. They launched to the space station on March 3 and are completing a six-month expediting to the ISS.

"We began the mission as crewmates, but now we're brothers," Al Neyadi, the UAE's first long-duration astronaut to the ISS, said on X (formerly known as Twitter) on Aug. 31). "Over the last 6 months, I gained a new family - with whom I shared expertise, traditions, and cultures, and experienced beautiful and challenging moments while creating unforgettable memories together."

UAE astronaut AlNeyadi's return to Earth postponed; new target date revealed

Crew-6 was supposed to undock from the ISS tomorrow, September 2

The departure of Crew-6, including UAE astronaut Sultan AlNeyadi, from the International Space Station (ISS) has been postponed due to unfavourable weather conditions near splashdown sites off the coast of Florida, Nasa and Space X announced on Friday.

The crew was supposed to undock from the ISS tomorrow, September 2.

The Mohammed Bin Rashid Space Centre (MBRSC) on Friday confirmed the postponement.

According to Nasa and SpaceX, the next available undocking opportunity is now no earlier than September 3, Sunday. This means AlNeyadi and his Crew-6 mates — Nasa astronauts Stephen Bowen and Woody Hoburg, and Roscosmos cosmonaut Andrey Fedyaev — are expected to come home on Monday, September 4, depending on weather conditions.

The US Space Agency earlier said it was monitoring the impact of Hurricane Idalia across seven potential splashdown sites off the coast of Florida this weekend in time for the return of Crew-6.

Return date

Nasa and SpaceX, provider of Dragon spacecraft Endeavour that will bring Crew-6 back to Earth, are looking at the next available undocking opportunity no earlier than 3.05pm (UAE time) on Sunday, September 3.

The splashdown or landing of Endeavour off the coast of Florida is expected no earlier than 8.07am (UAE time) the following day, Monday, pending weather evaluations.

Mission teams will meet on Friday evening to determine the viability of the next Crew-6 undock target.

Meanwhile, Nasa noted spacecraft Endeavour “remains healthy while currently docked to the space station as Crew-6 prepares for their return trip to Earth completing a nearly six-month science mission in orbit.”

Why there’s a delay

Every human space flight, including Crew-6 return depends on a variety of factors such as spacecraft readiness, recovery team readiness, weather condition, sea states, and other factors.

Mission teams evaluate the weather forecast for the splashdown time and recovery readiness at the primary and alternate splashdown sites to determine if it is a “go” or “no-go.”

"Splashdown locations are selected using defined priorities, starting with selecting a station departure date and time with the maximum number of return opportunities in geographically diverse locations to protect for weather changes. Teams also prioritise locations which require the shortest amount of time between undocking and splashdown based on orbital mechanics, and splashdown opportunities that occur in daylight hours," Nasa explained.

Revised schedule

Should the undocking from ISS happen on Sunday, here’s how Crew-6 return will be (all time stamps are based on UAE time zone, and subject to change depending on operations)
