Inspiration4’s crew of four civilian astronauts are just hours away from launching on a 3-day journey in orbit around Earth. 

But while they’re getting ready to blast off of our planet, the crew, who will lift off at 8:02 EDT tonight (Sept. 15) (0002 GMT Sept. 16) from NASA’s Kennedy Space Center in Florida, isn’t nervous, they’re excited!

Even SpaceX founder Elon Musk is excited. After changing his Twitter profile photo to the Inspiration4 crew photo, he tweeted “Watch Countdown on Netflix about Inspiration4 mission launching today,” encouraging his followers to follow along on the crew’s journey. 

Mission pilot Sian Proctor shared her excitement this afternoon on social media, tweeting “I’ve been waiting for this moment all my life. Thank you for all the well wishes & support. Let’s do this!”

Inspiration4 will make history!

Tonight’s (Sept. 15) Inspiration4 mission will make history in SO many ways!

First, this will be the first all-civilian mission to orbit. That means that this is the first time that a mission has launched to orbit with only civilians, or spaceflyers who are not “professional astronauts,” or astronauts employed by an agency like NASA, on board. 

This mission will also carry a crew who are making history themselves!

With this mission, pilot Sian Proctor has become history’s first Black female spacecraft pilot and the crew’s medical officer Hayley Arceneaux is set to be both the youngest American to ever go to space with this mission, and the first person to go to space with a prosthesis.

It’s launch week for SpaceX’s private Inspiration4 mission and the four civilians launching on the site have paid a final trip to their Falcon 9 rocket and the Crew Dragon Resilience, the ship that will be their home in space during the 3-day mission.

SpaceX is targeting an 8 p.m. EDT launch on Sept. 15 for the Inspiration4 mission, which will launch Shift4 entrepreneur and billionaire Jared Isaacman into space with crewmates Hayley Arceneaux, Sian Proctor and Chris Sembroski. Isaacman is financing the flight privately and gave away the three seats to his crewmates through fundraising efforts for St. Jude Children’s Research Hospital.

“One last touch of our Dragon capsule before launch,” wrote Proctor, Inspiration4’s  pilot and a geoscientist, on Twitter. 

“The awe visiting of our spaceship,” Arceneaux, a physician’s assistant at St. Jude, added. 

“Resilience is ready to roll. She is on the Falcon and it is a beautiful sight!” added Sembroski. 


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.

One week from launch!

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.
