SpaceX launched supplies to the International Space Station in a previously used spacecraft Saturday and then landed the rockets first-stage booster back on Earth. <\/p>\n
With the launch, SpaceXs Dragon capsule joins a small number of spacecraft, most notably NASAs space shuttles, to reenter space a first for the Hawthorne space company. <\/p>\n
The Falcon 9 rocket lifted off a little after 2 p.m. Pacific time from Launch Complex 39A at the Kennedy Space Center in Florida. The launch had originally been set for Thursday afternoon but was scrubbed because of weather conditions. <\/p>\n
The Dragon capsule for this mission was used in 2014 to carry supplies to the space station. For this launch, it was filled with almost 6,000 pounds of crew supplies, hardware and science research, including equipment to study neutron stars. <\/p>\n
In preparation for the flight, SpaceX replaced some parts on the Dragon, such as the heat shield. But most of the components, including the hull and thrusters, were reused, said Hans Koenigsmann, vice president of mission assurance at SpaceX. <\/p>\n
The majority of this Dragon has been in space before, he said during a prelaunch news conference earlier this week. <\/p>\n
About seven minutes after launch, the Falcon 9s first-stage booster landed upright at nearby Cape Canaveral Air Force Station. <\/p>\n
Successful landings for the first-stage booster have become so reliable that inspection processes for the booster will be streamlined from now on, Koenigsmann said at a post-launch news conference Saturday. <\/p>\n
The Dragon spacecraft deployed about 10 minutes after launch and should arrive at the space station around 7 a.m. Pacific time Monday. The spacecraft is expected to return to Earth in July, splashing down in the Pacific Ocean. <\/p>\n
SpaceX will then evaluate the Dragon, and if all goes well, the capsule could then be reused a couple more times, Koenigsmann said. <\/p>\n
Reusing a Dragon capsule is one more piece of the puzzle in creating a fully reusable launch system, said Marco Caceres, senior space analyst at the Teal Group. <\/p>\n
In March, SpaceX achieved one of its longtime goals by using a previously flown first-stage booster to launch a commercial communications satellite and then landing that booster on a floating platform at sea. <\/p>\n
During that same mission, the company successfully recovered the rockets fairing, a clamshell-like covering that protects satellites and other payloads. <\/p>\n
Successful reuse of the Dragon capsule is significant for SpaceXs materials technology, but in general, the spacecraft reuse is less significant than that of the booster, which required more cutting-edge technology to be able to land upright, Caceres said. <\/p>\n
SpaceX Chief Executive Elon Musk has said the first-stage booster is the most expensive part of the rocket. Company President Gwynne Shotwell has said that launch costs could eventually decrease by 30% by reusing rockets. <\/p>\n
Saturdays launch was SpaceXs seventh of the year as the company increases its launch cadence. Last year, SpaceX launched eight missions before a launchpad explosion that destroyed a rocket and commercial satellite, grounding the company for several months. <\/p>\n
