The 13-member shuttle-space station crew is working through a revised timeline today, focusing on logistics transfers, spacewalk preparations and the robotic transfer of spare parts and equipment from Endeavour to a work site on the station's solar power truss.

Flight planners built two timelines for today, one that included a focused inspection to better assess heat shield damage and one that did not. Late Friday, engineers decided there was no need for any additional inspections and the crew is working through the alternate flight plan today, moving the spare parts transfers up and devoting more time to logistics transfers.

"Early in the day, we're going to pull out what's called the Integrated Cargo Carrier and that's a piece of structure that's launched in the shuttle payload bay and includes three critical spares for the International Space Station, plus the (solar array) battery system that's going to be changed out on a later EVA," said space station Flight Director Derek Hassmann.

Mounted on the Integrated Cargo Carrier are a spare antenna assembly, along with a spare cooling system pump module and a replacement drive unit for the station's robot arm transporter. In addition, six 375-pound batteries are mounted on the carrier to replace aging batteries used by the station's oldest set of solar arrays. The batteries will be installed during the crew's third and fourth spacewalks.

"So we're going to use the shuttle robotic arm to pick the ICC out of the shuttle payload bay, we're going to hand it off to the station arm and then we're going to actually attach this Integrated Cargo Carrier at a point on the truss and then release it," Hassmann said.

"And then on EVA 2 (Monday), the spacewalking crew will move out to that work site on the truss and they're going to remove three of those space station spares, with the help of the robotic arm, and install those spares at places on the truss so they're there if and when we need them later down the road."

The second half of the day will be devoted to spacewalk preparations and logistics transfers to and from the shuttle.

"We'll be doing the standard work inside the airlock to get the tools set up, to get the suits set up and toward the end of the day, we'll do the final procedures review with the crew to prepare for EVA-2," Hassmann said.

Japanese astronaut Koichi Wakata plans to install replacement shock absorbers on the station crew's advanced resistive exercise device, a sophisticated workout machine that mimics the performance of exercise machines on Earth.

"Nothing performs exactly in space as it did on the ground," Hassmann said. "The crew has really enjoyed working on the ARED, they like it, they like the exercise it gives them. ... Koichi is going to change out a couple of the components that basically absorb the shock associated with that exercise. So we're hoping at the end of the day, that piece of exercise equipment will be recovered and back in normal operation."

Despite the demands of a combined crew of 13 astronauts and cosmonauts, Hassmann said the space station's systems are operating normally with no technical problems of any significance.

"The station systems continue to work extremely well," he said. "The big highlight (Saturday) was the activation and checkout of the (Japanese) Exposed Facility and that all went very well. The power, data and thermal systems are all up and running and the station systems continue to perform extremely well. We're not working any issues on the station side."

A Canadian Space Agency public affairs event with station astronaut Robert Thirsk and shuttle flight engineer Julie Payette is planned for 6:08 p.m. An Apollo 11 event, the John Glenn Lecture Series "40th Anniversary of Apollo 11" from the Smithsonian National and Space Museum, will be carried on NASA television starting at 8 p.m.
