NASA cleared its subsequent astronaut flight to the Worldwide Area Station for launch on Friday (Sept. 27), a weekend liftoff that may 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 Business Crew Program supervisor, instructed reporters Friday night in a press briefing. “We’re vertical on the pad, and the following huge exercise shall be loading the cargo right here this afternoon after which preparing for flight.” You may watch the Crew-9 launch reside on Area.com, courtesy of NASA and SpaceX, starting at 9:10 a.m. EDT (1310 GMT). You may as well watch the launch on NASA’s YouTube, NASA+ streaming channel and SpaceX’s X web 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 dimension.
A half-Dragon crew
For the primary time since a Might 2020 check flight, SpaceX is barely 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 were 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 check flight of Boeing’s Starliner spacecraft. However considerations 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 was a full eight-month spaceflight. This month, Williams even took command of the station’s present Expedition 72 crew whereas she and Wilmore anticipate 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 additional 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 house operations and a former astronaut, stated of Cardman and Wilson. “And we actually recognize how exhausting it’s to surrender a mission and wait a bit 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 house 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 positioned 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, in line with the Cape Canaveral Area Museum. In 1996, it was used to launch a Titan 3C rocket carrying the Manned Orbiting Laboratory army house station mockup and a Gemini capsule (with no crew aboard), in line with 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 will perform very similar to SpaceX’s Pad 39A web site. It additionally means extra flexibility for SpaceX.
“I feel working off of Pad 40 offers us lots of distinctive capabilities that we are able to make the most of,” Invoice Gerstenmaier, SpaceX’s vp of construct and flight reliability, instructed 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. And not using a second crew-certified pad, SpaceX wouldn’t have the ability to do each missions, Gerstenmaier stated.

“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 feel it is it is neat to have a backup functionality, or if one thing occurs to a pad, or there’s some harm 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 as a consequence of unhealthy 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 facet of the state) was tropical storm class winds and rain, NASA officers stated.
SpaceX did have to wash and repaint a part of the Dragon capsule after winds blew soot from an ordinary engine check again on the capsule earlier this week. That cleansing helped make sure the capsules radiators and photo voltaic arrays will work correctly in the course of the flight, NASA stated.
At the moment, Area Pressure climate officers forecast a 55% probability of excellent 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 obtainable, if wanted, NASA officers stated.
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).
