CAPE CANAVERAL, Fla. Feb 24 - Privately owned Space
Exploration Technologies plans to include landing legs on its
next Falcon 9 rocket, a key step toward developing a reusable,
lower-cost launcher, company officials said on Monday.
Ultimately, the firm, which is owned and operated by
technology entrepreneur Elon Musk, would like to fly its rockets
back to the launch site where they would land and be reused.
For now, the first stage of the rocket, which is discarded a
few minutes after liftoff, falls back into the ocean with so
much force it is destroyed.
SpaceX, as the company is known, tried in September 2013 to
cushion a rocket's fall by restarting its engines during the
descent. The test was nearly successful, but the rocket's
spinning choked off the flow of fuel and it smashed into the
For its next test, targeted for March 16, SpaceX will again
attempt the engine restarts and deploy four landing legs to
provide the Falcon 9 with more stability. SpaceX spokeswoman
Emily Shanklin puts the odds of success at less than 40 percent.
The legs will be attached to the base of the rocket and
stowed during flight. They are designed to deploy as the rocket
descends back toward the ocean.
"Given all the things that would have to go right, the
probability of recovering the first stage is low," Shanklin
wrote in an email. "It probably won't work, but we are getting
SpaceX has a parallel program to test precision landing
techniques. The company in October completed tests on an
experimental vehicle known as Grasshopper which successfully
touched down on its launch pad after reaching an altitude of
0.46 miles (740 meters).
The program has since relocated from SpaceX's McGregor,
Texas, test site to New Mexico's Spaceport America near Las
Cruces for higher-altitude flights.
SpaceX last year entered the commercial satellite launch
market with a price that already sharply undercuts its
competitors and so far a perfect track record. The company also
flies cargo the International Space Station for NASA and is
working on a capsule to fly astronauts as well.
The March 16 launch, which will be from Cape Canaveral Air
Force Station in Florida, will be the third of 12 station
resupply missions under SpaceX's $1.6 billion contract with
SpaceX also flies from Vandenberg Air Force Base in
California and has a preliminary agreement with NASA to take
over one of the mothballed space shuttle launch pads at the
Kennedy Space Center in Florida. A fourth launch site in a
commercial spaceport has not yet been selected, although
Brownsville, Texas, is considered the front-runner.
