and on March 9, Space X performed a static fire test, where the first stage was to be fired without taking off.
The test aborted at T-2 seconds due to a failure in the system designed to pump high-pressure helium from the launch pad into the first stage turbopumps, which would get them spinning in preparation for launch.
In October 2016, Space X CEO Elon Musk announced an upcoming "final upgrade" called Falcon 9 Block 5, which will feature increased engine thrust, improved landing legs, and other minor improvements to help recovery and reuse.
While Space X spent its own money to develop its previous launcher, the Falcon 1, development of the Falcon 9 was accelerated by NASA funding parts of development costs and committing to purchase several commercial flights if specific capabilities were demonstrated.
Variants include the retired v1.0 and v1.1, as well as the currently operational "Full Thrust" v1.2 evolution.In 2008, Space X won a Commercial Resupply Services (CRS) contract NASA's Commercial Orbital Transportation Services (COTS) program to deliver cargo to the International Space Station (ISS) using the Falcon 9 and Dragon capsule.The first mission under this contract launched in October 2012.The space logistics delivery contract was worth Space X has only come this far by building upon the incredible achievements of NASA, having NASA as an anchor tenant for launch, and receiving expert advice and mentorship throughout the development process.Space X would like to extend a special thanks to the NASA COTS office for their continued support and guidance throughout this process.
