The astronauts have signed off for the night. They spent a busy day inspecting the shuttle's heat shield and preparing for the upcoming mission at the space station. The voluminous inspection data has been downlinked to engineers on the ground for analysis to determine if any follow-up checks will be required.

The crew also extended the docking ring that connects to the shuttle's port on the space station and set up the centerline camera to be used in the final approach and tested various rendezvous tools to be used Sunday night.

Other work accomplished during Flight Day 2 included prepping the spacewalking suits and staging equipment to be transferred during the station visit.

Wakeup time for docking day is 1:29 p.m. EDT.

The Discovery astronauts conducted an inch-by-inch inspection of the most critical sections of the shuttle's heat shield Saturday, examining the ship's nose cap and wing leading edge panels with a laser scanner on the end of a 50-foot-boom attached to the shuttle's robot arm.

Discovery reaction control jets have been fired for the latest course correction maneuver on the path to reach the space station. This burn lasted 13 seconds and changed the shuttle's velocity by about two miles per hour.

The Orbiter Boom Sensor System has been locked down in the payload bay, its job of inspecting Discovery's heat shield complete for today. The boom will be used again late in the mission for another round of observations to check for space debris impacts.

The port wing sweeps by the inspection boom have been completed by the astronauts. Ground analysts will need a day or two to review the data.

The crew will return the 50-foot-long structure back into its cradle in the payload bay as the work day winds down. Also upcoming on the to-do list is installation of the centerline camera in the Orbiter Docking System to help commander Rick Sturckow during tomorrow's approach to the space station. And the docking ring will be extended in preparation for linkup with the station's Harmony module.

Post-launch checks of the reinforced carbon-carbon panels on the leading edge of Discovery's port wing are underway.

The crew made quick work of the orbiter nose checks.

The left wing inspections are next up in this multi-hour job to survey the shuttle to look for any signs of launch damage. The precautionary safety inspection has become a standard activity for all post-Columbia shuttle crews.

The astronauts have swung the inspection boom into position out in front of Discovery to get a closeup look on the shuttle's nose cap. The crew will be working while eating lunch to get caught up on the timeline for this second part of the inspection sequence.

Danny Olivas, Christer Fuglesang and Nicole Stott have checked out their spacewalking suits to be worn during the three EVAs planned during shuttle Discovery's mission at the space station.

Inspections of space shuttle Discovery's starboard wing just finished. The extensive imagery and laser data will be analyzed by specialists on the ground to determine if the spacecraft's heat shield suffered any serious damage during Friday night's launch.

Inspections of the starboard wing have gotten underway now. Overseeing this work is pilot Kevin Ford and mission specialists Pat Forrester and Jose Hernandez.

Down on the lower deck of the spacecraft, the mission's spacewalkers are testing and readying three the spacesuits to be worn during the upcoming excursions outside the International Space Station.

The Orbiter Boom Sensor System, anchored on the end of shuttle Discovery's robot arm, has been lifted it out of the payload bay to begin today's heat shield inspections. Scans on the starboard side of the shuttle will be performed first.

Space shuttle Discovery's robot arm, under the control of pilot Kevin Ford and mission specialist Pat Forrester, has grappled the Orbiter Boom Sensor System for the upcoming unberthing of the inspection device.

The latest in the series of burns by Discovery on its trek to the International Space Station has been executed using the right-hand Orbital Maneuvering System engine for 16 seconds to change the shuttle's velocity 12 feet per second.

The Discovery astronauts faced a routine-but-busy first day in space Saturday, inspecting the shuttle's heat shield, checking out their spacesuits and readying the ship for docking Sunday with the International Space Station.

Mission Control has awakened the astronauts with the song "Back in the Saddle Again" by Gene Autry played for commander Rick Sturckow to begin Flight Day 2, the crew's first full day in orbit.

Today will be spent inspecting Discovery's heat shield for any signs of launch damage, a routine task for shuttle crews. Other activities include checking out the spacesuits to be worn during the mission's spacewalks and preparing equipment for tomorrow's docking to the space station.
