SpaceX's Falcon 9 rocket on Sunday returned safely to Earth, touching down at
Landing Zone 1 after launching the Dragon spacecraft into low-Earth orbit.
This is the second such landing at Cape Canaveral by a returning Falcon 9
rocket. The first was Falcon 9 Flight 20's return on Dec. 22. SpaceX also
accomplished three successful drone-ship landings this spring.
"As with previous first stage land and drone-ship landings from
SpaceX, this achievement is a testament to the leadership and innovation of
America's commercial space industry," NASA spokesperson Cheryl Warner told TechNewsWorld.
The Dragon's 5,000-lb. payload included science and crew supplies, a space
suit, and an international docking adapter that will enable commercial
spacecraft to dock to the station when transporting astronauts as part of
NASA's upcoming Commercial Crew Program.
The ISS crew will use the station's 58-foot robotic arm to reach out and
capture the Dragon spacecraft, and attach it to the station at 7 a.m. ET on
Wednesday.
Reusable Rockets on
the Way?
"This is an exciting time, as we will all soon find out whether
reusability really is the key to unlocking lower launch costs and higher levels
of space activity, but it will probably be at least another year before early
results can be measured and properly analyzed," noted Micah Walter-Range,
director of research and analysis at the space foundation
"Before I say this is the age of reusable rockets, I would want to see
them being reflown with paying customers or cargo aboard, and the companies
making a higher profit as a result," he told TechNewsWorld.
"If it turns out that the cost of inspecting and refurbishing flown
hardware eats up the cost savings from not having to build new hardware, there's
no net gain," Walter-Range noted.
"In real terms, the cost to lift a pound into orbit has declined by
about 90 percent since the beginning of the Space Age," noted Michael
Jude, a program manager at Stratecast/Frost & Sullivan.
"Launch costs will need to decline by nearly as much," he told
TechNewsWorld. "Part of this will be the cost of launch hardware, but the
real cost driver is the overhead associated with assembly, management and
payload deployment."
Been There, Done That
There were two efforts to make reusable rockets in the 1980s, noted Jim
McGregor, a principal analyst at Tirias Research.
One was a single stage to orbit -- a single-stage rocket that could launch
and land in one piece. The other was the National Aerospace Plane, or NASP --
the Rockwell X-30.
The NASP was designed to "replace the space shuttle and be able to fly
directly into space at Mach 25 (25 times the speed of sound)," McGregor
told TechNewsWorld. "Unfortunately, the Clinton administration killed both
efforts."
The return of the Falcon 9's first stage to land safely at Landing Zone 1
shows SpaceX "should reduce the number of future failures to recover the
booster," he suggested. "It's a step in regaining lost momentum in
our space technology, [and] will make delivering people and equipment to space
less expensive."
What does SpaceX's success imply for NASA's future?
"NASA is really becoming irrelevant in terms of launch
capability," Jude suggested. It's definitely the high-cost carrier."
NASA "is probably much more useful providing an incentive for
commercial launch operations," he said. "If commercial carriers begin
taking astronauts to the ISS, its costs will decline," and that might lead
it to contract for most of its space initiatives.
The Next Challenge for
SpaceX
SpaceX is planning an unmanned mission to Mars in 2018 or 2019, Jude said.
NASA "is ponying up some money to help, but it will be a SpaceX
operation."
The Mars mission will require a "fully functional Falcon 9 Heavy and a
substantial number of improvements on the Dragon capsule," Jude noted.
"If it can accomplish this, then it will be ahead of the competition.
