“This booster has launched eight astronauts, three dragon capsules and one geostationary spacecraft,” said Julianna Scheiman, SpaceX’s director of civil satellite missions. “Reusability is key to lowering the cost of launch, which in turn enables greater investment and scientific research.”
After launching IXPE into space, the booster will be brought back and landed on the SpaceX drone ship “Just Read the Instructions” off the coast of Florida.

Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a 90% chance of favorable conditions for liftoff, with the cumulus cloud rule serving as the primary weather concern.
“We’re looking at just a very, very slight chance of a weather issue,” said Mike McAleenan, 45th Weather Squadron, Space Launch Delta 45. “There will be winds out of the west, northwest, and just a slight chance of cumulus clouds to impact the area.”
IXPE will study the polarization of X-rays coming to us from some of the universe’s most extreme sources, including black holes and dead stars known as pulsars. Since its arrival in Florida last month, the spacecraft has undergone several tests and eclipsed multiple milestones at Kennedy, including final processing, mating to the rocket, and encapsulation. On Tuesday, the rocket and spacecraft were transported to the launch pad and raised to the vertical position.

The weather outlook for Thursday’s early morning launch of NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft from Kennedy Space Center bumped up in a positive direction. Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron now predict a 90% chance of favorable conditions for liftoff, increasing by 10% from a day ago. The cumulus cloud rule is the primary weather concern.
IXPE is scheduled to launch aboard a SpaceX Falcon 9 rocket from the Florida spaceport’s Launch Complex 39A on Dec. 9, 2021, at 1 a.m. EST. The launch is managed by NASA’s Launch Services Program, based at Kennedy.
IXPE is the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron stars.
Today, NASA will hold an IXPE payload briefing at 1 p.m. and a prelaunch news briefing at 5:30 p.m. Both will be broadcast on NASA Television, the NASA app, and the agency’s website. Live launch coverage will begin Dec. 9 at 12:30 a.m.

Following a series of “aliveness” tests to verify the health of the spacecraft, teams mated the structure to the payload adapter – a ring that interfaces between the spacecraft and the top of the rocket. Next, multi-layer insulation was installed to provide thermal protection for the spacecraft in space.
After items such as optic and sensitive instrument covers were removed, the nose fairing and the spacecraft were brought together, signaling a major achievement in the mission: encapsulation.
“This is when you mate the spacecraft to the rocket, so it’s the two halves coming together,” said Brett Perkins, launch site integration manager for NASA’s Launch Services Program, based at Kennedy. “There are several critical lifting operations of the spacecraft. You have to be very careful and methodical; a lot of hardware comes together during this timeframe.”
The mission is scheduled to launch no earlier than Thursday, Dec. 9, at 1 a.m. EST, on a SpaceX Falcon 9 rocket from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. IXPE is the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron stars.
“IXPE is filling a data gap in polarized X-rays, which we don’t have a lot of information on,” Perkins said. “This mission is a small part of a bigger picture – a bigger effort – to learn more about the universe and how it works.”
On Tuesday, Dec. 7, NASA will hold an IXPE payload briefing at 1 p.m. and a prelaunch news briefing at 5:30 p.m. Live launch coverage will begin Dec. 9 at 12:30 a.m. All will be broadcast on NASA Television, the NASA app, and the agency’s website.

Weeks of work are paying off for engineers and technicians from NASA’s Kennedy Space Center in Florida who have been preparing the agency’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft since its arrival by truck from Ball Aerospace in Boulder, Colorado, to Cape Canaveral Space Force Station in Florida on Nov. 5, 2021.
Important activities continue inside SpaceX’s Payload Processing Facility in advance of the next major milestone – mating the spacecraft to the launch vehicle.
“We’ve been doing final checkouts and testing on IXPE prior to mating activities,” said Jake Shriver, mission integration engineer for NASA’s Launch Services Program (LSP), based at Kennedy.
IXPE is targeted to launch aboard a SpaceX Falcon 9 rocket from Kennedy’s Launch Complex 39A on Dec. 9, at 1 a.m. EST. The mission is NASA’s first dedicated to measuring X-ray polarization. The launch is managed by LSP.
Following mating of the spacecraft to the launch vehicle will be encapsulation, where the fairing halves come together around the spacecraft. A couple of days before launch, the encapsulated assembly will roll out to the pad to be mated to the first- and second-stage rocket boosters.
IXPE will study changes in the polarization of X-ray light through some of the universe’s most extreme sources, including black holes, dead stars known as pulsars, and more. Polarization contains clues that helps scientists better understand these mysterious phenomena.
“I can’t wait for IXPE to get into space and start returning science data,” Shriver said. “The mission is going to do amazing things for the astrophysics and science communities.”
