SpaceX reusable rocket launch and landing test successful

SpaceX sent a rocket soaring toward orbit Monday night with 11 small satellites, its first mission since an accident last summer. Then it landed the leftover 15-storey booster back on Earth, safely.

It was the first time a rocket returned to land vertically at Cape Canaveral, Fla., and a tremendous success for SpaceX.

Company employees broke into cheers and chants following the touchdown 10 minutes after liftoff. Previous landing attempts failed, but those aimed for an ocean platform.

• Spaceflightdisasters show it's still 'very hard' to get into orbit
• Reusable rocket landed successfully by Blue Origin

SpaceXemployees jammed company headquarters in Hawthorne, Calif.,anxiously awaiting success outside Mission Control. They cheered at full throttle when the first stage separated cleanly two minutes into flight and reoriented itself for an unprecedented return to Cape Canaveral.

Then the roar became deafening, as TV cameras showed the first-stage booster landing right on a giant X at Cape Canaveral Air Force Station.SpaceXcommentators called it "incredibly exciting" and were visibly moved by the feat.

The company ledby billionaireElonMusk isstriving for reusability to drive launch costs down and open upspace to more people. Muskalso runs the Tesla electric car company.

"Welcome back, baby!" Musk tweeted after touchdown.

"It's a revolutionary moment," Musk later told reporters. "Noone has ever brought a booster, an orbital-class booster, backintact."

The touchdown was a secondary objective forSpaceX. The first was hoisting the satellites forOrbComm, a New Jersey-based communication company. All 11 were successfully deployed.

"Here she comes back,"OrbCommchief executive officer MarcEisenbergsaid via Twitter. "Bullseye."

Supply ship destroyed in June

On its previous flight back in June,SpaceX'sFalcon 9 rocket failed shortly after liftoff, destroying a supply ship intended for the International Space Station. A snapped strut in the upper stage was to blame.SpaceXspent months correcting the problem and improving the unmanned rocket. It hopes to resume supply runs for NASA in February.

The booster-landing zone, a former Atlas missile-launching site, is about six miles from the launch pad.SpaceXis leasing the touchdown area marked by a giant X from the Air Force. The reinforced concrete provides a stable surface, unlike the barges used for the initial attempts, primarily for increased safety.

Three tries at vertical landings of the first-stage boosters earlier this year failed; in each case, the segment aimed for a modified barge off the coast of Jacksonville, Fla.

This time, Musk opted for a true land landing.

Blue Origin, another billionaire's rocket company, successfully landed a booster last month in West Texas. That rocket, though, had been used for a suborbital flight. TheSpaceXbooster was more powerful and flying faster in order to put satellites into orbit.
