Countdown clocks resumed ticking Saturday for the shuttle Discovery's delayed launch Tuesday to boost the $1.5-billion Hubble Space Telescope into orbit. Engineers also readied the shuttle Columbia for rollout to its launch pad today for a May flight. Discovery's carefully scripted countdown began on time at 3 p.m. The ship's five-member crew is set to blast off at 5:31 a.m.

The shuttle Discovery's crew flew back to Florida on Sunday for blastoff Tuesday on a critical flight to carry the $1.5-billion Hubble Space Telescope into orbit, 14 days late because of hydraulic problems. "Well, here we are again!" Discovery skipper Loren J. Shriver said shortly after the crew arrived. "We feel very confident that things are going to go well this time."

Launch crews moved steadily through the countdown Thursday in preparation for the launching of the space shuttle Atlantis, aiming for a liftoff at 6:56 a.m. PDT today. They delayed a rollback of the service structure around the vehicle for eight hours so that technicians could relieve a pressure buildup in a tank serving an auxiliary maneuvering unit, but with that problem fixed they were to begin fueling its gigantic external tank with liquid hydrogen and liquid oxygen shortly after midnight.

The much-delayed launch of the Hubble Space Telescope was back on track Monday, and officials expected the space shuttle Discovery to blast off at around 5:31 a.m. PDT today. "The astronomers are starting to tingle again," Lennard A. Fisk, chief scientist for the National Aeronautics and Space Administration, said Monday.

The space shuttle Discovery rode on searing flames into orbit this afternoon, carrying a secret military cargo intended to boost the nation's ability to spy on Soviet communications. The launch into a sky marred only by the slightest wisps of clouds took place under unprecedented security for a shuttle operation, intended to foil attempts to determine the nature of the mysterious mission by hiding its launch time until the final nine minutes of the countdown. The launch was flawless.

The Discovery astronauts triumphantly launched the $1.5-billion Hubble Space Telescope one orbit late today after last-ditch commands from Earth freed a stuck solar panel, narrowly averting a daring emergency spacewalk. The telescope began orbiting Earth every 97.3 minutes at an altitude of 380 miles--high above the atmosphere, which has limited the view of ground-based telescopes. "Discovery, go for Hubble release," Mission Control told the crew at 12:37 p.m. PDT.
