For SpaceX, All Systems 'Go' for Epic Reusable Rocket Landing Test

Koenigsmann also stressed that getting Dragon safely to the space station is Tuesday's main mission objective, and that the first-stage return test is merely a secondary goal, albeit an exciting and attention-grabbing one.

But SpaceX is committing to developing fully and rapidly reusable rockets over the long haul. Such a breakthrough could slash the cost of spaceflight dramatically, experts and advocates say.

"I think it really would be a game changer in the space launch industry, " Commercial Spaceflight Federation President Eric Stallmer told

Reusable rockets "would open up new markets and opportunities, new possibilities, " he added. "If it does happen, it's really going to change the way we launch things."

SpaceX has been building up to Tuesday's attempt for a while. For example, the company successfully brought a Falcon 9 first stage down for a soft ocean splashdown twice last year, once in April and then again in July. But those tests achieved a landing precision of around 6 miles (10 kilometers), while the stage will need to hit its target within 33 feet (10 meters) or so on Tuesday, SpaceX representatives have said.

Tuesday's launch — which should be visible along large stretches of the U.S. East Coast — will also kick off SpaceX's fifth robotic cargo mission to the space station for NASA. The California-based company holds a .6 billion contract with the space agency to fly 12 such missions; the first four have all been successful.

SpaceX's Drone Spaceport Ship Another company, Virginia-based Orbital Sciences Corp., signed a .9 billion NASA deal to fly eight robotic resupply missions using its Cygnus spacecraft and Antares rocket. Orbital's first two flights went well, but the third failed when Antares exploded just seconds after liftoff in late October.

Dragon is loaded with more than 5, 000 lbs. (2, 270 kilograms) of food, scientific experiments and spare parts for this latest journey. The capsule is scheduled to arrive at the orbiting lab early Thursday morning (Jan. 8); astronauts will then grapple it using the station's huge robotic arm. Dragon will stay berthed to the orbiting lab for about a month, then return to Earth for a Pacific Ocean splashdown and retrieval.

The weather looks good for an ontime liftoff; the latest forecasts peg chances of favorable conditions at 70 percent on Tuesday morning. If the Falcon 9 doesn't get off the ground Tuesday, the next launch opportunity will come on Friday (Jan. 9).
