STS-96 Day 5 Highlights
Back to STS-96 Flight Day 04 Highlights:
- On Monday, May 31, 1999, 7:00 a.m. CDT, STS-96 MCC Status Report # 10
- For the first time in six months, astronauts entered the
International Space Station delivering supplies and preparing the
outpost to receive its first resident crew, scheduled to arrive in
- Mission Specialists Tammy Jernigan and Russian Space Agency
cosmonaut Valery Tokarev opened the hatch into the Unity module at
8:14 p.m. CDT Sunday, then continued through Pressurized Mating
Adapter 1 into the Zarya module at 9:07 p.m. Commander Kent Rominger
and the rest of the crew - Pilot Rick Husband and Mission Specialists
Ellen Ochoa, Dan Barry and Canadian Space Agency astronaut Julie
Payette - soon followed.
- After inspecting their expanded living quarters, the crew began
transferring supplies, equipment and water that will be left aboard,
an effort that was coordinated by Ochoa. The bulk of the supplies and
equipment were shipped up in a double SPACEHAB module carried in
Discovery's cargo bay.
- Payette and Tokarev replaced 12 of 18 battery recharge controllers
in the Russian-built Zarya module. Zarya has six batteries, which have
been experiencing a slight loss in capacity during recharge. Each
battery has three "charge controllers," known by the Russian
acronym MIRTS. The astronauts replaced controllers for four of the
batteries, and are scheduled to replace the recharge controllers for
the other two later today. The work was carefully coordinated with
flight controllers in the Russian Mission Control Center outside
Moscow, who issued commands to turn the battery systems on and off via
ground-based communication stations. Barry and Tokarev also installed
a series of "mufflers" over fans inside Zarya to reduce
noise levels in that module.
- Barry and Husband replaced a power distribution unit and transceiver
for the Early Communications System in the Unity module, restoring
that system to its full capability. This supplemental communications
system enables flight controllers to send commands to the station from
the Mission Control complex in Houston.
- Near the end of their workday, Rominger, Jernigan and Barry
discussed the progress of their mission, including Jernigan and
Barry's space walk and last night's entry into the International Space
Station, with NBC's "Today," show, CBS "This
Morning" and CNN.
- The crew is scheduled to begin its sleep period at 8:20 a.m. CDT,
and will awaken at 4:20 p.m. to continue their work in the ISS.
- The next STS-96 mission status report will be issued at
approximately 7 p.m. Central time or as events warrant.
- On Monday, May 31, 1999, 6:00 p.m. CDT, STS-96 MCC Status Report # 11
- Discovery's crew of seven awoke to the country and western tune
"Amarillo by Morning" to begin flight day six on orbit. The
George Strait version was played in honor of Pilot Rick Husband, who
is from Amarillo, Texas.
- Today, most of the crew will be involved in logistics transfer
activities within the Discovery/ISS orbiting complex. Husband and
Mission Specialists Ellen Ochoa, Tammy Jernigan and Dan Barry have a
significant portion of their day dedicated to moving transfer bags of
different sizes and shapes from the SPACEHAB module in Discovery's
cargo bay to resting places inside the International Space Station.
Some 2,900 pounds of logistics items and water will be transferred
before the crew bids goodbye to its orbiting work site on Thursday.
- Discovery's crew will also complete maintenance activities in
support of the station. Early in the workday, Russian cosmonaut
Valery Tokarev and Canadian astronaut Julie Payette will change out
the last battery recharge controller modules attached to two of
Zarya's storage batteries. These recharging units, also known as
microelectronic charge/discharge current integrator units, determine
the battery charge level. Since mid-April, flight controllers had
been monitoring a slight decrease in this level, and the on-orbit
maintenance work is expected to allow the batteries to charge fully
- Later, Barry and Tokarev will put the remaining sound mufflers
inside the Zarya module. Ambient noise from air circulating fans and
equipment could be somewhat distracting to crew members spending time
on orbit, so mufflers are being installed to dampen the noise. After
the install, Barry will measure sound levels at different positions
inside the module.
- At 12:20 a.m. Tuesday, Commander Kent Rominger and Tokarev will
conduct a news conference with Russian media located at the Mission
Control Center in Moscow.
- The day will end with a logistics transfer briefing conducted by
Payette. The crew is scheduled to turn in at about 8 a.m. CDT
- Discovery and the International Space Station are in excellent
health orbiting 240 miles above the Earth. The next mission status
report will be issued Tuesday morning.
