The shuttle Atlantis came through it's ground-shaking launch and high-speed climb to orbit in good shape Monday with no obvious signs of any significant debris strikes or other problems, officials said.

"At this point, there's absolutely no imagery observations indicating any concern at all," astronaut Greg H. Johnson radioed Atlantis from mission control in Houston.

"That's outstanding, Houston," commander Scott Altman replied from Atlantis. "Thanks for that early word."

Mike Moses, chairman of NASA's mission management team at the Kennedy Space Center, said even though engineers saw "nothing of note" in the ascent imagery, "we'll let the teams do all the right things? and go off and talk and review all the data. We'll inspect the vehicle in the next several days to make sure we came out of ascent clean."

Flight controllers hope to have a preliminary assessment of the health of the shuttle's heat shield by Wednesday evening, before the a spacewalk Thursday to begin refurbishing the Hubble Space Telescope.

Otherwise, Moses said, Atlantis came through launch in good shape despite alarms that sounded early in the climb to space and a possible short in a subsystem.

"There were a couple of issues when we lifted off," Moses said. "Right away off the pad, ASA-1 (aerosurface actuator 1), which is a flight control feedback system that controls the aerosurfaces, all the TVCs (thrust vector controllers), it's one of four systems and it failed.

"It looks like the power failed to that unit and took it down. Again, it was one of four, it was no issue, it bypassed itself. The crew's going to leave it alone for now while the teams look at it. We don't need it again until entry, obviously, so we'll do a thorough data review to find out what really happened to that box and whether we can reset it or not. Again, there's no real rush, there's no impact to that box being down.

"The other nuisance, on the left main engine there was a hydrogen-out pressure (signal) basically that was flashing transient, it kind of changed its signature on us," Moses said. "When it tripped the limit, it rang an alarm on board and I think it did that two or three times on the way uphill. It's just a transient 'ducer, it's there for awareness, it didn't feed into any software, it wasn't part of any control loop. So no impact at all to the main engines or their performance."

With ascent behind them, Altman and his crewmates turned their attention to setting up the shuttle's on-orbit computer network and checking out the ship's robot arm for an evening inspection of the payload bay and the upper surfaces of the crew module. The astronauts also plan to check out the flight support system cradle at the back of the cargo bay that will be used to hold Hubble in place after the telescope is captured Wednesday.

Crew sleep is scheduled to begin at 9:01 p.m.
