‘Three’s Company’: SpaceX hangar houses three used boosters
About a week after SpaceX landed its third Falcon 9 first stage on a solid surface—the second on a drone ship at sea—and brought it back to Port Canaveral, the company posted images of the three boosters in the Horizontal Integration Facility (HIF) at Launch Complex 39A.
The booster on the left (banner photo) landed at Landing Zone 1 (LZ-1) on Dec. 21, 2015. It was already test-fired at Launch Complex 40, showing no major problems with the engines. The recovered stage is slated to go in front of the company’s headquarters in Hawthorne, California.
The most recent booster landed on the drone ship “Of Course I Still Love You” and was offloaded over the last number of days before being transported to the HIF on Saturday.
It landed after powering the JCSAT-14 mission toward its designated orbit. Because the payload was being delivered to a geostationary transfer orbit (GTO), it was going much faster than the previous landing attempt. The speed requirements for GTO missions allow very little fuel for recovery attempts.
As such, a burn to slow the stage down before entering the atmosphere was not conducted. Additionally, the final landing burn used three engines, instead of the single center engine, to slow the vehicle down much faster, thus using less fuel. The conditions this booster endured were much rougher than that of CRS-8 or even the Dec. 21 LZ-1 landing.
“Most recent rocket took max damage due to [very] high entry velocity,”Musk tweeted. “Will be our life leader for ground tests to confirm others are good.”
Indeed images taken of the booster as it was being transported showed paint melted away and more burn scars on the exterior than the previous two.
It is unclear if SpaceX will certify this booster for a re-flight first before the CRS-8 booster. Either way, the results from the JCSAT-14 stage will show just how well the Falcon 9 will fair on high velocity landings. Roughly half of all of the company’s payloads have a destination of GTO.

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.
