X-Ray Polarimetry Explorer (IXPE)
NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) mission will allow astronomers to discover, for the first time, the hidden details of some of the most exotic astronomical objects in our universe.
The goal of the IXPE mission is to expand understanding of high-energy astrophysical processes and sources, in support of NASA's first science objective in astrophysics: "Discover how the universe works".
IXPE is part of NASA's Astrophysics Explorers Program and is a collaboration between NASA’s Marshall Space Flight Center, the Italian Space Agency, and Ball Aerospace.
The X-ray polarization detectors will be provided by the Italian Space Agency. Other partners include the University of Colorado Boulder, Stanford University, McGill University in Canada, MIT (Massachusetts Institute of Technology), and OHB Italia.
This is the first space mission dedicated to observing polarized X-rays from extreme objects such as neutron stars, stellar and supermassive black holes.
The estimated cost of the mission and its two-year operation is $188 million with the cost of the launch itself estimated at $50.3 million.

Falcon 9 is a reusable, two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of people and payloads into Earth orbit and beyond.
Falcon 9 is the world’s first orbital-class reusable rocket.
Stats

Total reflights: 255
The Falcon 9 has launched 49 humans into orbit since May 2020
Specs
Height: 70 m / 229.6 ft
Diameter: 3.7 m / 12 ft
Mass: 549,054 kg / 1,207,920 lb
Payload to LEO: 22,800 kg / 50,265 lb

On January 24, 2021, Falcon 9 launched the first ride-share mission to Sun Synchronous Orbit. It was delivering a record-setting 143 satellites to space. And while this was an important mission for SpaceX in itself, it was also the moment Falcon 9 overtook United Launch Alliance’s Atlas V for the total number of consecutive successful launches.
SpaceX’s Falcon 9 had become America’s workhorse rocket, launching 31 times in 2021. It has already beaten that record this year, launching almost an average of once a week. While most of the launches deliver Starlink satellites to orbit, the company is still launching the most commercial payloads to orbit, too.
Falcon 9 is a medium-lift launch vehicle, with the capability to launch over 22.8 metric tonnes to low earth orbit. Unlike any other rocket, its first stage lands back on Earth after separating from its second stage. In part, this allows SpaceX to offer the cheapest option for most customers with payloads that need to reach orbit.
Under its ride-share program, a kilogram can be placed in a sun-synchronous orbit for a mere 1.1 million dollars, far cheaper than all other currently operating small satellite launch vehicles.
The reusability and fast booster turnaround times have made Falcon 9 the preferred choice for private companies and government agencies. This has allowed SpaceX to capture a huge portion of the launch market.

NASA's historic Kennedy Space Center is located on Cape Canaveral, Florida, and has hosted decades of historic space missions since the early days of the Apollo program.
Today, Kennedy Space Center is a multi-user spaceport and hosts private companies like Boeing, Lockheed Martin, SpaceX, and others.
SpaceX leases Launch Complex 39A at NASA's flagship facility and uses the pad to launch its Falcon Heavy and Falcon 9 rockets. The pad is also used to launch missions for the Commercial Crew Program for which SpaceX launches astronauts to the Space Station for NASA aboard their Crew Dragon capsule.
Launch Complex 39A was previously used by NASA to launch the Apollo 11 mission to land the first humans on the moon and Space Shuttle missions to assemble the International Space Station and upgrade the Hubble Space Telescope.

The Autonomous Spaceport Drone Ship "Just Read The Instructions" is one of two Atlantic Ocean recovery ships for SpaceX's Falcon 9 and Falcon Heavy rockets. It was first used exclusively in the Pacific Ocean before being brought through the Panama Canal to Louisiana and then Port Canaveral for refits and upgrades. Its first Atlantic Ocean mission supported the 8th Starlink launch in June 2020.
