SpaceX Dragon Makes First Commercial Deliver To IIS

SpaceX is making history as the first commercial delivery ship, dubbed Dragon, made its voyage to the International Space Station on Friday. It is the first capsule in orbit funded by the private sector.

The Associated Press reports that astronauts Donald Pettit and Andre Kuipers used the space station’s robot arm to snare the SpaceX capsule after a few hours of extra maneuvering.The capsule approached the International Space Station for the historic docking Friday after sailing through a practice rendezvous the day before.

The unmanned SpaceX Dragon is delivering a half-ton of supplies to the International Space Station, an achievement previously reserved for a small, elite group of government agencies.

On Thursday, the capsule made a practice fly-by. It returned early Friday, and the capsule had to go through a series of stop-and-go demonstrations to prove it was under good operating control.

As the capsule drew within 100 feet (33 meters), flight controllers told it to retreat as the SpaceX company resolved a problem with on-board tracking sensors. Stray reflections from the Japanese part of the space station were interfering with the sensors, officials said. The docking operation soon resumed.

NASA ordered extra checks of the Dragon’s imagers as the capsule drew closer to the space station, putting the operation slightly behind schedule. Given that the Dragon is a new type of vehicle and this is a test flight, the space agency said it wanted to proceed cautiously.

A collision at orbital speed – 17,500 mph (28,160 kph) – could prove disastrous for the space station.

President Barack Obama is pushing commercial ventures in orbit so the U.S. space agency, NASA, can concentrate on grander destinations like asteroids and Mars. Once companies master supply runs, they hope to tackle astronaut ferry runs.

The California-based SpaceX – officially known as Space Exploration Technologies Corp. – is one of several companies vying for the chance to launch Americans from their homeland after NASA’s final shuttle flight last summer. To get to the space station, NASA astronauts now must go through Russia, an expensive and embarrassing situation for the U.S. after a half-century of orbital self-sufficiency.
