Day-by-day timeline for Space Shuttle Discovery

FLIGHT DAY 1:

Following launch, Discovery’s crew sets up the on-board laptop computer network, checks out the Shuttle Remote Manipulator System (SRMS) and conducts Detailed Test Objective (DTO) 850, Water Spray Boiler Cooling with Water/PGME Antifreeze.

• The crew begins the Shuttle Remote Manipulator System (SRMS) checkout.

• Overnight, Mission Control will downlink data from the Discovery’s Wing Leading Edge (WLE) sensors for analysis by engineers looking for sites of potential debris impacts during launch.

FLIGHT DAY 2:

The Shuttle crew completes SRMS checkout and installs the centerline camera in the Orbiter Docking System.

• The crew grapples and unberths the Orbiter Boom & Sensor System (OBSS) and conducts an SRMS/OBSS survey of Discovery’s wing leading edges and nose cap.

• The Shuttle’s Ku band antenna is deployed.

• The crew begins a checkout of the rendezvous tools.

• The crew plays back handheld launch video of the External Tank.

• The crew conducts photography of the Orbital Maneuvering System (OMS) pods.

• Orbiter Docking System (ODS) is extended.

• The crew performs system checks on the Extravehicular Mobility Unit (EMU) spacesuits and tools in preparation for upcoming spacewalks.

• The crew berths the OBSS.

• The crew surveys Discovery’s upper surfaces and the crew cabin using the SRMS.

FLIGHT DAY 3:

The crew begins the final stage of rendezvous operations as Discovery closes in for docking with the International Space Station.

• Discovery performs the Rendezvous Pitch Maneuver, enabling the Space Station crew to photograph Discovery’s thermal protection systems.

• Discovery docks with the Space Station.

• The Shuttle and Station crews open the hatches and shake hands.

• The crews begin transferring cargo from Discovery to the Station.

• The crew uses the Space Station RMS (SSRMS) to grapple the OBSS and hands it off to the SRMS.

FLIGHT DAY 4:

The crew grapples the Raffaello Multi-Purpose Logistics Module (MPLM) with the SSRMS, unberths the MPLM from Discovery and installs it on the Unity module’s Common Berthing Mechanism (CBM).

• The SSRMS ungrapples from the MPLM and begins its walk-off to the Mobile Base System (MBS).

• The crew uses the OBSS to conduct a survey of Discovery’s heat-protection tiles.

• The crew activates the MPLM and ingresses.

• The crew configures tools for the first spacewalk and begins Extravehicular Activity (EVA) pre-breathe.

• The crew transfers EVA tools and equipment to the Shuttle airlock.

• The crew performs a checkout of the Simplified Aid for EVA Rescue.

• The hatches between Discovery and the Space Station are closed and Discovery’s cabin is depressurized to 10.2 pounds per square inch (psi) in preparation for the first spacewalk, to be done from the Shuttle airlock.

FLIGHT DAY 5:

• Final preparations begin for the first spacewalk.

• The Shuttle crew begins the first spacewalk from the Shuttle airlock.

• Hatches between Discovery and the Space Station are opened. Two crew members move to the Station to perform SSRMS EVA support. Transfer activity resumes.

• The External Stowage Platform-2 (ESP-2) Attachment Device (ESPAD) is unberthed from Discovery and installed onto Quest.

• The GPS antenna is removed and replaced on the S0 Truss.

• The spacewalkers reconfigure power cables in the Z1 Truss to restore power to control moment gyroscope to.

• The crew uses OBSS to scan damaged reinforced carbon-carbon samples on the DTO pallet.

• The Shuttle and Station hatches are closed, and the spacewalking astronauts ingress Discovery’s airlock.

• Shuttle and Station hatches are reopened.

• The Station crew makes preparations for the Control Moment Gyroscope (CMG) removal and replacement.

FLIGHT DAY 6:

• Transfers continue from Discovery to the Space Station.

• Procedures are reviewed for the second spacewalk, EVA tools are checked out and EVA pre-breathe begins.

• Hatches between Discovery and the Space Station are closed and the Shuttle cabin is depressurized to 10.2 psi.

FLIGHT DAY 7:

• The second spacewalk begins.

• Hatches between Discovery and the Station are reopened. Two crew members move to the Station to perform EVA SSRMS support, and transfers resume.

• Spacewalkers remove and replace CMG 1, then perform a checkout of the new CMG.

• Shuttle and Station hatches are closed and the spacewalkers ingress the Shuttle airlock.

• New Station CMG 1 is started.

• Shuttle and Station hatches are opened.

FLIGHT DAY 8

• Transfers resume between Discovery and the Station.

• Discovery’s crew conducts its in-flight news conference.

• The crew begins its off-duty period.

• The Shuttle crew reviews procedures, configures tools and begins pre-breathe for tomorrow’s third spacewalk from the Shuttle airlock.

• Shuttle and Station hatches are closed. The Shuttle cabin is depressurized to 10.2 psi in preparation for tomorrow’s third spacewalk.

FLIGHT DAY 9:

• The third spacewalk of the mission begins.

• Hatches between Discovery and the Station are opened.

• Spacewalkers install an external camera and illuminator on P1 Truss.

• SSMRS grapples and unberths ESP-2 from Discovery’s payload bay.

• Two MISSE experiments are retrieved from the Quest airlock, and a new MISSE is installed at the top of the P6 Truss.

• SSRMS delivers ESP-2 to ESPAD, and spacewalkers install.

• Transfers continue between Shuttle and Station.

• SSRMS ungrapples ESP-2 and maneuvers to MPLM.

• Hatches between Discovery and Station are closed, the spacewalkers re-enter the Shuttle airlock and the third EVA ends.
