They "may" build great cars, but.....

A Japanese spacecraft which failed on its landmark mission to collect
asteroid samples suffered a new setback with its return to Earth
delayed by three years until 2010.
The Hayabusa spacecraft, which last month approached the asteroid 290
million kilometers (180 million miles) from Earth, has been out of
control since Friday because of a gas burst caused by leaking fuel.
The six-meter (20-foot) unmanned spacecraft was set to depart in
mid-December, when the distance between Earth and the asteroid is
ideal, and drop a capsule in the Australian outback in June 2007.
But the Japan Aerospace Exploration Agency said it now expected the
spacecraft back in June 2010 as it will be another three years before
the travelling distance is practical.
"This is disappointing, but we'll spend the coming year to rescue the
craft and retrieve it in June 2010 if we can control it again by the
beginning of 2007," project manager Junichiro Kawaguchi said at a
press conference.
"There is a good possibility that the craft can be controlled again,"
he added.
The expedition was to be the first to retrieve samples from an
asteroid, helping scientists learn more about how the solar system was
created and study how to deflect a potential celestial object on a
collision course with Earth.
In a humiliating setback, the space agency said last week that the
spacecraft which was launched in May 2003 likely failed to collect the
asteroid dust.
The mission was all the more difficult because the potato-shaped
Itokawa asteroid -- 540 meters (1,782 feet) long and 270 meters wide
at the larger end -- is revolving and has very low gravity, making it
tough for Hayabusa to land on the jagged surface.
Hideo Nagasu, former director of National Aerospace Laboratory of
Japan, dismissed criticism that the mission was a complete failure.
"I think they are doing a good job," he told AFP. "The asteroid is
believed to have remained in its initial condition from the time the
solar system was created. They innovated to send a spacecraft there
and take samples.
"The craft did arrive there and sent photos of Itokawa. It was such a
challenging mission," he said. "It wouldn't be fair to criticize that
the mission's achievement was zero."
But he doubted the space program would try again to take samples from
an asteroid after the 12.7 billion yen (100 million dollar) Itokawa
mission.
"There are many projects lining up after this," Nagasu said.
Japan's space program has been eyeing more ambitious projects since it
successfully sent a weather satellite into space in February.
That was Japan's first launch since November 2003 when it had to
destroy a rocket carrying a satellite to spy on North Korea shortly
after lift-off when one of two rocket boosters failed to separate.
The failure was all the more embarrassing as it came one month after
China, Japan's neighbor and growing rival, became the third country
after the United States and the former Soviet Union to launch a
successful manned space flight.
