KENNEDY SPACE CENTER, Fla. — SpaceX keeps racking up contractual wins. The most recent to be announced was for a NASA mission, one that serves to demonstrate that the company’s 74 Falcon 9 and Falcon Heavy flights – has not gone unnoticed.

NASA announced on Monday July 8, 2019 that SpaceX had won the contract to launch the Imaging X-Ray Polarimetry Explorer (IXPE) spacecraft. That flight is currently planned tot take place in April of 2021.

A flight-proven Falcon 9 has been tapped to launch IXPE from historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida. If everything goes as planned, it will deliver the spacecraft into a circular 335-mile (540 km) orbit over the Equator. IXPE will be the lightest payload to ever launch on a Falcon 9, weighing in at only 710 lbs (320 Kg).

The total launch cost for the mission has been listed at $50.3 million.

IXPE is a part of NASA’s Small explorer class of missions. The spacecraft is composed of three X-ray telescopes that will look for polarized X-rays from black holes, pulsars, and neutron stars. It has a planned mission life of two years. The spacecraft is currently being manufactured by Ball Aerospace.

SpaceX’s President and Chief Operating Officer, Gwynne Shotwell, made the following statement after the announcement of the contract award.

“SpaceX is honored that NASA continues to place its trust in our proven launch vehicles to deliver important science payloads to orbit. IXPE will serve as SpaceX’s sixth contracted mission under NASA’s LSP, two of which were successfully launched in 2016 and 2018, increasing the agency’s scientific observational capabilities.”

Given the prices SpaceX charges to send payloads to orbit, the Hawthorne, California-based company is being awarded more and more contracts. Two missions, Jason-3 and TESS have already taken to the skies atop one of SpaceX’s offerings under the agency’s Launch Services Program (LSP). The company has also been awarded the contracts for the SWOTSentinel-6A, and DART missions.

Who says price doesn’t matter? And probably before a decent track record it didn’t but seems to be not the case today unfortunately for the naysayers . Even eight engines and reusing a first stage is no longer sufficient reason not to.
