SpaceX got a little more fire than it bargained for when it tested a Falcon 9 rocket over the weekend.
The two-stage Falcon 9 behaved just fine during the standard "static fire" test at NASA's Kennedy Space Center (KSC) in Florida on Sunday (May 28) — but a small chunk of neighboring Merritt Island National Wildlife Refuge blazed up as a result.
Firefighters with the U.S. Fish and Wildlife Service (USFWS) quickly got the fire under control by repeatedly drenching it with water dropped from a helicopter. The wildfire topped out at a mere 4 acres (1.6 hectares), USFWS officials said via Twitter Sunday.
The Falcon 9, meanwhile, is all set for a historic Thursday (June 1) launch from KSC's famous Pad 39A that will send a used spacecraft skyward — a rare feat accomplished by just a few vehicles, including the Air Force's robotic X-37B space plane and NASA's space shuttle orbiters. (Space shuttles once lifted off from Pad 39A, as did most of NASA's Apollo moon missions.)
The pre-flown craft is SpaceX's robotic Dragon cargo capsule, which will carry lots of scientific experiments, hardware, food and other supplies up to the International Space Station (ISS). This particular Dragon has already flown to the ISS once before, in September 2014.
SpaceX also aims to land the Falcon 9's first stage back on Earth during Thursday's launch, which is scheduled to take place at 5:55 p.m. EDT (2155 GMT). You can watch all the action live here at Space.com when the time comes.
If all goes according to plan, Dragon will arrive at the ISS on Sunday (June 4). The capsule will stay attached to the orbiting lab for nearly a month, returning to Earth for a soft, ocean splashdown on July 2.
SpaceX's rocket-landing activities are part of the company's attempt to develop fully and rapidly reusable launch systems, a breakthrough that company founder and CEO Elon Musk has said will revolutionize spaceflight.
To date, SpaceX has landed Falcon 9 first stages on 10 separate occasions. The company has re-flown one of these landed boosters; that milestone occurred on March 30, during the successful launch of the SES-10 communications satellite.
Editor's Note: A previous version of this story incorrectly stated that no pre-flown spacecraft has launched since 2011. The Air Force's reusable X-37B space plane has completed several missions since then.
