The hatches swung

closed between Discovery and the International Space Station at 4:52

this afternoon Central time so that the shuttleís cabin pressure could

be lowered in preparation for a space walk Thursday by Dan Barry and

Pat Forrester.

In preparation

for that Extravehicular Activity (EVA), the crew spent part of the day

checking out the suits that will be worn for the planned six and a half

hour excursion to install an ammonia servicing unit on the outside of

the station. It contains spare ammonia that could be used in the stationís

cooling system if needed. They also will attach an experiment to the

station to expose samples of engineering materials to the space environment.

The samples will be returned to Earth for analysis in about a year.

A second space

walk currently is planned for Saturday to hook up heater cables for

the first of several girder-like truss structures, that will be delivered

to the station next year.

Meanwhile, members

of the stationís Expedition Two crew continued the handover of station

operations to their Expedition Three replacements. Throughout the handover,

the stowage of equipment and supplies inside the Leonardo Multi-Purpose

Logistics Module continued. Some 5,200 pounds of supplies was confirmed

on board the station and will be unpacked and stowed by the Expedition

Three crew after Discovery departs early next week.

Early in the day,

Russian flight controllers completed the reloading of upgraded software

into the computers of the Zvezda module in preparation for next monthís

arrival of a new module to the station, the Russian Docking Compartment,

which will serve as a new docking port for visiting Russian vehicles.

The Russian flight

control team continues to track preparations of a Soyuz spacecraft set

to deliver the next Progress supply vehicle to the station. Launch from

the Baikonur Cosmodrome in Kazakhstan remains targeted for Tuesday with

docking Aug. 23.

Early Thursday

morning, the Expedition Three crew of Frank Culbertson, Vladimir Dezhurov

and Mikhail Tyurin plan to televise a commemorative message marking

the one-thousandth day in space for the International Space Station.

It was Nov. 20, 1998 when the first element ñ Zarya ñ was launched atop

a Proton rocket initiating the construction of the orbiting outpost.

Discovery and

the station are orbiting the Earth every 90 minutes at an average altitude

of 246 statute miles with no systems issues being worked by the flight

control team. The next status report will be issued around 6 a.m. Thursday,

or earlier, if events warrant.
