In just about 10 minutes, the Falcon 9 rocket’s nine Merlin engines will roar to life, sending SpaceX’s Falcon 9 rocket and NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft into space. The rocket has been fueled with liquid oxygen and RP-1 – rocket-grade kerosene. The Falcon 9’s engines are chilling in preparation for launch.
Excitement is building as IXPE, NASA’s first dedicated mission to measuring X-ray polarization, nears launch. 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.
The weather outlook for NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) launch from Kennedy Space Center remains outstanding. Weather officials with Cape Canaveral Space Force Station’s 45th Weather Squadron predict a greater than 90% chance of favorable conditions for liftoff of NASA’s first dedicated mission to measuring X-ray polarization.
Propellant load is underway, which eliminates IXPE’s 90-minute launch window.
“We have committed to this and we are committed to a T-zero at 1 a.m.,” said Mic Woltman of NASA Communications.
IXPE will study targets over a broad range of types of astronomical X-ray sources with emphasis on black holes and neutron stars.
The mission will accomplish, for the first time, high-sensitivity measurements of the polarization of X-rays coming from some of the most exciting types of astronomical objects – neutron stars and black holes.
The mission will accomplish, for the first time, imaging X-ray polarization measurements from extended objects such as exploded stars and jets attached to super-massive black holes.
The mission involves the first use of Kennedy’s Launch Control Center Firing Room 4 for the launch of an LSP mission.
IXPE is the second LSP mission to fly a previously flown Falcon 9 booster.

The weather outlook for today’s early morning launch of NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft from Kennedy Space Center is terrific. 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.
A collaboration between NASA and the Italian Space Agency, IXPE is NASA’s first mission dedicated to measuring X-ray polarization. Launch, which is managed by NASA’s Launch Services Program, based at Kennedy, is targeted for 1 a.m. EST from the Florida spaceport’s Launch Complex 39A.

NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) mission sounds cool, and even has a catchy name. But what is IXPE’s goal and how did the project come about? Here is a more in-depth look at IXPE, NASA’s first satellite dedicated to measuring X-ray polarization.
IXPE is going to explore some of the most extreme and mysterious objects in the universe – including black holes and pulsars – and the X-rays they emit. It is the first mission that will map the polarization of many of these objects.
IXPE carries three state-of-the-art space telescopes with special polarization-sensitive detectors. Polarization is a property of light that holds clues to the environment from which the light originates. By providing the first-ever dedicated look at polarized X-rays, IXPE will help us discover the secrets of some of the most extreme cosmic objects of the universe: the remnants of supernova explosions, neutron stars and black holes in our galaxy, and super massive black holes at the centers of galaxies.
NASA selected IXPE as a Small Explorer mission in 2017. The IXPE project is a collaboration between NASA and the Italian Space Agency. NASA’s Marshall Space Flight Center in Huntsville, Alabama manages the IXPE mission. Ball Aerospace, headquartered in Broomfield, Colorado, manages spacecraft operations with support from the University of Colorado at Boulder.
NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the Explorers Program for the agency’s Science Mission Directorate in Washington.

Standing tall atop a SpaceX Falcon 9 rocket, IXPE is set to lift off from Kennedy Space Center’s Launch Complex 39A in just about 90 minutes (1 a.m. EST, Thursday, Dec. 9). The Launch is managed by NASA’s Launch Services Program, based at Kennedy.

It has been all good news on the weather front thus far, but we will keep you posted on any updates from Cape Canaveral Space Force Station’s 45th Weather Squadron prior to launch of NASA’s first mission dedicated to measuring X-ray polarization.

“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.
IXPE is scheduled to lift off aboard a SpaceX Falcon 9 rocket from the Florida spaceport’s Launch Complex 39A on Thursday, Dec. 9, at 1 a.m. EST.

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.
