Tokyo A Japanese spacecraft apparently succeeded in landing on an asteroid and collecting surface samples today, part of an unprecedented mission to bring the material back to Earth, Japan's space agency said.
The Hayabusa probe touched down for only a few seconds on the faraway asteroid - long enough to collect powder from its surface - and lifted off again to transmit data to mission controllers, said Kiyotaka Yashiro, a spokesman for JAXA, Japan's space agency.
"The initial movements and operations look very good," Yashiro said. "The process of sampling also seems to have gone very well.
More data confirming the mission's success is expected later in the day after scientists have examined additional transmissions from the probe, Yashiro said.
But JAXA won't know if Hayabusa actually collected surface samples until it returns to Earth. It is expected to touch down in the Australian Outback in June 2007.
Hayabusa was launched in May 2003 and has until early December before it must begin its 180 million-mile journey home.
A NASA probe collected data for two weeks from the asteroid Eros in 2001, but did not return with samples.
