- <p> It had been more than five years since an American walked in
- space, but the crew of the shuttle Atlantis did not seem rusty.
- On a first, unscheduled 4 1/2-hour jaunt, astronauts Jerry Ross
- and Jay Apt freed a balky antenna on an observatory satellite,
- permitting the $617 million device to be placed in orbit. The
- astronauts later tested sleds that haul large objects through
- space on a rail.
- </p>
- <p> The success of last week's mission, however, did not
- settle the ongoing debate about the value of manned spaced
- flights. NASA officials have long insisted that human crews are
- vital because even the most sophisticated robots lack the
- ability to respond to unexpected situations. If the U.S. is
- serious about exploring the solar system, they say, unmanned
- probes to distant celestial bodies must be followed by missions
- involving humans.
- </p>
- <p> Critics counter that unmanned, expendable rockets can loft
- most satellites into orbit at far less cost and with much less
- risk than the reusable shuttle, which has been plagued by
- technological glitches. The argument will heat up this spring
- as Congress decides whether to fund a $30 billion orbiting space
- station. NASA plans to use the shuttle to ferry up astronauts
- to assemble the station, then supply it with unmanned rockets.
- If the lawmakers decide to scrub the station, the shuttle will
- be without a clearly defined role.
