SpaceX’s Inspiration4 private all-civilian orbital mission: Live updates


New launch date

Inspiration4 is now targeting liftoff of no earlier than 8 p.m. EDT on Sept. 15 (midnight Sept. 16 GMT), mission officials announced this morning — a 24-hour slip from the original launch window. 

Teams from SpaceX and Inspiration4 met on Thursday (Sept. 9) for a follow-on flight readiness review and a weather briefing, Inspiration4 officials said in a statement

“After evaluating the readiness of the Falcon 9 rocket, Dragon spacecraft, associated ground systems, recovery assets and other key elements of SpaceX’s human spaceflight system, and the current weather forecasts of conditions at the launch site, along the ascent corridor, and at the landing locations off the coasts of Florida for a safe return of the crew a few days later, teams agreed to now target no earlier than 8:00 p.m. ET on Wednesday, September 15 for liftoff,” the statement reads.

“This will allow additional time for final preparations, vehicle checkouts and data reviews. SpaceX and Inspiration4 will narrow down the launch window to five hours approximately three days before liftoff,” the statement added.

The four private astronauts launching with SpaceX on the Inspiration4 mission have completed all of their training and will head to NASA’s Kennedy Space Center in Cape Canaveral, Florida today for their last days on Earth before liftoff. The launch is targeted for Tuesday, Sept. 14 at 8 p.m. EDT (0000 Sept. 15 GMT).

“Our Inspiration4 crew has completed astronaut training at SpaceX’s headquarters in Hawthorne, CA and is en route to Kennedy Space Center in Florida for final preparations and launch!” the Inspiration4 team wrote in an update today.

“At the last meeting today we heard… “Inspiration4 is signed off for spaceflight”… we are now on the way to with a busy schedule right up to launch,” Jared Isaacman, the Shift4 entrepreneur and billionaire financing the flight, wrote in another update.

Isaacman will command the unprecedented three-day private spaceflight with three others, all civilians like him, on the flight. He’ll be joined by geoscientist Sian Proctor as the mission’s pilot; Hayley Arceneaux as medical officer and data engineer Chris Sembroski as mission specialist.

SpaceX’s Inspiration4 mission, the world’s 1st private all-civilian spaceflight, is now one week away from a planned Sept. 15 launch from NASA’s Kennedy Space Center in Florida.

The mission, financed by Shift4 entrepreneur and billionaire Jared Isaacman, will launch him and three others on a three-day orbital mission on SpaceX’s Falcon 9 rocket and the Crew Dragon Resilience. Isaacman will be joined by geoscientist Sian Proctor as pilot; and bone cancer survivor Hayley Arceneaux and data engineer Chris Sembroski as mission specialists. Arceneaux, who works with St. Jude Children’s Hospital, was selected for the flight, with Proctor and Sembroski nabbing their seats as part of an online contest. 

“Alright, let’s go to space, @rookisaacman,” Arceneaux wrote on Twitter Tuesday (Sept. 7) while sharing a photo of herself and Isaacman boarding a plane. 

The four astronauts-to-be have spent the last few months training to fly on SpaceX’s Crew Dragon Resilience, which launched NASA’s Crew-1 astronauts to the International Space Station in 2020. But the Inspiration4 mission will not visit the station. Instead, it will orbit the Earth and has a huge glass dome in place of its docking port to offer stunning views to the Dragon crew.
