The first commercially contracted re-supply mission to the International Space Station (ISS) has begun.

对国际空间站的首个商业化补给任务已经开始实行。

A Dragon flew a demonstration mission to the space station in May
 
A Falcon2 rocket carrying a Dragon cargo3 capsule lifted clear of Cape4 Canaveral in Florida at 20:35.
 
The robotic Dragon ship will deliver 400kg of food, clothing, experiments and spares to the orbiting platform's six astronauts.
 
It is the maiden5 flight(处女航) in a sequence of 12 missions that California's SpaceX company is performing for Nasa.
 
The US space agency is looking to the private sector6 to assume routine transport duties to and from low-Earth orbit.
 
It has given SpaceX a $1.6bn contract to keep the ISS stocked up with essentials, restoring a re-supply capability7 that the US lost when it retired8 the shuttles last year.
 
The terms of the contract kicked in following a successful test of Dragon's systems in May. 
 
That demonstration saw the capsule berth9 with the ISS - the first commercially designed and built vehicle to do so - and then return safely to Earth.
 
Nasa has a second company it hopes also can soon begin operational cargo deliveries to the station.
 
The Orbital Sciences Corporation (OSC) will shortly test its new Antares rocket before undertaking10 its own ISS demonstration with a robotic vessel11 called Cygnus.
 
If that mission - tipped to take place next year - goes well then it will trigger a $1.9bn contract for Orbital.
 
Nasa wants eventually to put astronaut transport in the hands of the private sector, too.
 
SpaceX is eyeing this business as well, and is developing the critical life-support and safety systems that would turn Dragon into a human-rated vehicle. The company says it is just a few years away from being able to provide an astronaut "taxi" service.
 
Nasa's policy of outsourcing its cargo and crew transport needs is intended to find savings12 that can be ploughed back into building a rocket and capsule system capable of taking humans beyond low-Earth to more challenging destinations.
 
"We're handing off to the private sector our transportation to the International Space Station so that Nasa can focus on what we do best - exploring even deeper into our Solar System, with missions to an asteroid13 and Mars on the horizon," explained agency administrator14 Charles Bolden.
 
Sunday's nine-minute, 14-second ascent15 to orbit appeared flawless. 
 
The Falcon dropped the Dragon off in an elliptical(椭圆的) path running from 197km above the Earth out to 328km.
 
"Dragon was inserted into a picture-perfect orbit," said SpaceX president Gwynne Shotwell. "Its solar arrays deployed16 and it's driving its way to station. So, that's just awesome17."
 
Dragon must raise itself to the ISS's altitude, which is presently at more than 400km.
 
It is scheduled to arrive at the station on Wednesday. It will follow the routine established in May of parking itself just below the platform so that it can be grabbed by a robotic arm and pulled into a berthing18 port. 
 
The attachment19 should take place at about 0540GMT.
 
Dragon is expected to return to Earth at the end of the month.
 
Its cargo then will include broken machinery20 and science materials that need to be handed back to researchers.
