Falcon 9 static fire test performed at LC-39A
KENNEDY SPACE CENTER, Fla. — Launch Complex 39A roared to life for the first time since the end of the Space Shuttle era, albeit for only a few seconds, as SpaceX conducted a static fire test of its Falcon 9 rocket.
At 4:30 p.m EST (21:30 GMT) Feb. 12, 2017, the Falcon 9’s nine Merlin 1D engines ignited to ensure everything was operating as expected before the next week’s planned launch of the Commercial Resupply Services (CRS) 10 mission to the International Space Station.
The test involved a full countdown and fueling of the rocket. When the engines ignited, they fired a short 3.5-second burst before the flight computer automatically commanded an abort. SpaceX engineers will now pore over the data over the coming days to ensure all is well on the booster.
Liftoff for the CRS-10 mission is scheduled for 10:01 a.m. EST (15:01 GMT) Feb. 18. This will be the first launch from the complex since the final Space Shuttle mission, STS-135 in July 2011.
Once in orbit, the CRS-10 Dragon capsule will take about two days to reach the outpost. It will deliver 4,473 pounds (2,029 kilograms) of pressurized and 2,154 pounds (977 kilograms) of unpressurized cargo.
About nine minutes after liftoff, the first stage of the Falcon 9, after detaching from the second stage and its payload, will return back to nearby Cape Canaveral Air Force Station’s Landing Zone 1.
This will be the third time one of SpaceX’s Falcon 9 first stages will attempt a ground landing, rather than on a drone ship at sea. It will also be the first ground landing during daylight hours.
When CRS-10 does get off the ground, it will be the first East Coast launch since the Sept. 1, 2016, explosion in the minutes before a static fire test. The explosion destroyed the rocket and Amos 6 satellite it was carrying. Additionally, it severely damaged Space Launch Complex 40 (SLC-40), which is just south of LC-39A.
SpaceX has since resolved the issue that caused the accident and returned the Falcon 9 to flight. That launch, the Iridium-1 mission, took to the skies Jan. 14, 2017, from Vandenberg Air Force Base in California.
After CRS-10, SpaceX will launch one of its last expendable Falcon 9 rockets when it sends the EchoStar 23 communications satellite into a geostationary transfer orbit. That mission currently has a no-earlier-than launch date of Feb. 28.

While at Washburn, he was the managing editor of the student run newspaper, the Washburn Review. He also has a blog about the International Space Station, called Orbital Velocity. He met with members of the SpaceFlight Insider team during the flight of a United Launch Alliance Atlas V 551 rocket with the MUOS-4 satellite. Richardson joined our team shortly thereafter. His passion for space ignited when he watched Space Shuttle Discovery launch into space Oct. 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, he soon realized his true calling was communicating to others about space. Since joining SpaceFlight Insider in 2015, Richardson has worked to increase the quality of our content, eventually becoming our managing editor. @TheSpaceWriter
