NASA cleared its subsequent astronaut flight to the Worldwide Area Station for launch on Friday (Sept. 27), a weekend liftoff that can assist return two Boeing Starliner astronauts house and break in a brand new launch pad for SpaceX.
A SpaceX Falcon 9 rocket and Dragon spacecraft will launch two Crew-9 astronauts, NASA veteran Nick Hague and Russian cosmonaut Alexandr Gorbunov, to the ISS from Cape Canaveral Area Pressure Station in Florida on Saturday, Sept. 28. Liftoff is ready for 1:17 p.m. EDT (1517 GMT).
“We’re continuing towards launch and go to proceed time of 1:17 p.m. tomorrow,” Steve Stich, NASA’s Industrial Crew Program supervisor, informed reporters Friday night in a press briefing. “We’re vertical on the pad, and the subsequent huge exercise shall be loading the cargo right here this afternoon after which preparing for flight.” You possibly can watch the Crew-9 launch dwell on Area.com, courtesy of NASA and SpaceX, starting at 9:10 a.m. EDT (1310 GMT). You may also watch the launch on NASA’s YouTube, NASA+ streaming channel and SpaceX’s X page.
SpaceX’s Crew-9 mission is a break from the corporate’s typical ISS crew rotation flights for NASA in a few methods.
First, there’s the crew measurement.
A half-Dragon crew
For the primary time since a Could 2020 take a look at flight, SpaceX is simply launching two astronauts to the ISS on a Dragon spacecraft. That is as a result of NASA pulled two different crewmembers — its unique commander Zena Cardman and three-time shuttle flier Stephanie Wilson — from the flight to make room for 2 astronauts which have been caught on the ISS since their Boeing Starliner capsule return to Earth with out them on Sept. 7.
NASA astronauts Butch Wilmore and Sunita Williams launched to the station in June on the first-ever crewed take a look at flight of Boeing’s Starliner spacecraft. However issues over Starliner’s thruster system prompted NASA to maintain Wilmore and Williams on the ISS and return Starliner house uncrewed. Their unique eight-day mission became a full eight-month spaceflight. This month, Williams even took command of the station’s present Expedition 72 crew whereas she and Wilmore watch for a visit house on Crew-9’s Dragon capsule in February 2025.
To accommodate the Starliner astronauts’ return, Cardman and Wilson had to surrender their seats, setting apart years of coaching for his or her Crew-9 flight, which Hague is now commanding. NASA is submitting the 2 empty Crew-9 seats with further cargo and provides, together with a brand new Dragon spacesuit for Wilmore (one for Williams is already aboard the ISS).
“I simply need you to know we’ll discover spots for them to fly,” Ken Bowersox, NASA’s affiliate administrator for area operations and a former astronaut, mentioned of Cardman and Wilson. “And we actually recognize how onerous it’s to surrender a mission and wait a bit of bit longer.”
Additionally new for Crew-9’s flight is SpaceX’s selection of launch pad.

SpaceX’s new astronaut pad
Till now, SpaceX has launched each astronaut mission for NASA from the Kennedy Area Heart’s historic Launch Advanced 39A, which hosted Apollo and area shuttle launches earlier than SpaceX leased it from the U.S. company. Nonetheless, SpaceX additionally launches uncrewed missions from its Area Launch Advanced-40 pad at Cape Canaveral Area Pressure Station, which is situated close to the Kennedy Area Heart.
The pad was previously utilized by the U.S. Air Pressure for Titan rocket launches from 1965 to 2005, according to the Cape Canaveral Area Museum. In 1996, it was used to launch a Titan 3C rocket carrying the Manned Orbiting Laboratory navy area station mockup and a Gemini capsule (with no crew aboard), according to NASA.
The SLC-40 pad, newly upgraded to host astronaut launches, now sports activities a crew entry tower and arm, a chute-based pad escape system to whisk crews away in case of hazard and may operate very similar to SpaceX’s Pad 39A website. It additionally means extra flexibility for SpaceX.
“I believe working off of Pad 40 offers us numerous distinctive capabilities that we are able to benefit from,” Invoice Gerstenmaier, SpaceX’s vp of construct and flight reliability, informed reporters.
Having a second crew-capable launch pad permits SpaceX respiration room to deal with sophisticated launches at each its Florida launch websites. The corporate is at the moment getting ready Pad 39A to launch a triple-booster Falcon Heavy rocket carrying NASA’s flagship Europa Clipper mission to Jupiter’s moon Europa on Oct. 10. With no second crew-certified pad, SpaceX wouldn’t be capable to do each missions, Gerstenmaier mentioned.

“It additionally permits us to place two crew missions fairly shut collectively, back-to-back, and see the place we’re if we have to do this,” he added. “So I believe it is it is neat to have a backup functionality, or if one thing occurs to a pad, or there’s some injury to a pad, or we have to take a pad down for upkeep.”
SpaceX and NASA beforehand focused Sept. 26 to launch the Crew-9 mission, however postponed it to Sept. 28 on account of dangerous climate from Hurricane Helene, which made landfall on the Gulf Coast of Florida on what would have been the missions’ unique launch day. The wet fallout from that storm on Florida’s Area Coast (on the alternative aspect of the state) was tropical storm class winds and rain, NASA officers mentioned.
SpaceX did have to scrub and repaint a part of the Dragon capsule after winds blew soot from a regular engine take a look at again on the capsule earlier this week. That cleansing helped make sure the capsules radiators and photo voltaic arrays will work correctly throughout the flight, NASA mentioned.
At present, Area Pressure climate officers forecast a 55% probability of fine climate on Saturday for Crew-9’s launch. These circumstances enhance to 60% “go” on its backup day Sunday (Sept. 29). One other backup launch day on Monday (Sept. 30) is accessible, if wanted, NASA officers mentioned.
Editor’s observe: Tune in to Area.com early Saturday, Sept. 28, to observe SpaceX’s Crew-9 astronaut launch for NASA. The launch webcast will start at 9:10 a.m. EDT (1310 GMT). A post-launch press convention is scheduled for 3 p.m. EDT (1900 GMT).
