SpaceX becomes first private firm to launch craft to space station

The Saturday launch attempt was scrubbed at the last second when computers
detected high pressure in the central engine of the Falcon 9.

SpaceX engineers discovered the
root cause was a faulty check valve.

California-based SpaceX is the first of several US competitors to try sending
its own spacecraft to the ISS with the goal of restoring US access to space
for human travellers by 2015.

The company successfully test-launched its Falcon 9 rocket in June 2010, then
made history with its Dragon launch in December 2010, becoming the first
commercial outfit to send a spacecraft into orbit and back.

Its reusable Dragon capsule has been built to carry both cargo and up to seven
crew.

Until now, only the space agencies of Russia, Japan and Europe have been able
to send supply ships to the ISS.

The three-decade US shuttle program, which ferried astronauts and cargo to the
research outpost, ended for good in 2011, leaving Russia as the sole taxi to
the ISS until private industry comes up with a replacement.

The US space agency has given SpaceX about $390 million so far of the total
$680 million that the company has spent on cargo development. SpaceX has a
$1.6 billion contract with NASA for future supply missions.

Orbital Sciences Corporation is working on its own supply ship, with a
preliminary launch scheduled for later this year, and has a $1.9 billion
contract with NASA.

SpaceX also gets funding from NASA for a separate effort to develop a
commercial crew vehicle for carrying astronauts to space, along with
competitors Blue Origin, Boeing and Sierra Nevada.

How significant is the SpaceX launch?

In a few years’ time, SpaceX says it will be able to undercut the hefty price
NASA pays Russia for US astronauts to get a seat aboard the Soyuz space
capsule – around $63 million a ticket.

But in the meantime, SpaceX and NASA have both cautioned that the attempt is
risky.

“Demonstration launches are conducted to determine potential issues so
that they might be addressed and – by their very nature – carry a
significant risk,” SpaceX said in a statement on Monday.

“If any aspect of the mission is not successful, SpaceX will learn from
the experience and try again.”

If the launch goes as planned on Tuesday, Dragon would orbit the Earth on May
23 as it travels toward the ISS.

On May 24, the spacecraft’s sensors and flight systems are to undergo a series
of tests to see if the craft is ready to berth with the space station,
including a complicated fly-under at a distance of about 1.5 miles.

If NASA gives the green light, the Dragon will then approach the ISS on May 25
in an attempt to berth with the station.

The astronauts on board the ISS will manoeuvre the station’s robotic arm to
help capture the capsule and attach it to the orbiting research outpost.

The hatch of the Dragon is set to open on May 26 for unloading and restocking.
On May 31, the Dragon is to detach from the station and make a safe landing
in the Pacific Ocean off the coast of southern California.
