NASA Space Station On-Orbit Status 29 March 2018

NASA Television has begun coverage of today’s spacewalk, as Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA prepare to work outside the International Space Station for approximately 6.5 hours.
Today’s spacewalk was originally scheduled to begin at 8:10 a.m. However, suit leak checks took longer than anticipated and has put them approximately 60-90 minutes behind the original timeline.

The objective of today’s spacewalk will be to will install wireless communications antennas on the Tranquility module, replace a camera system on the port truss and remove suspect hoses from a cooling system.

The wireless communications equipment will enhance payload data processing for the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) experiment being flown to the station on a future SpaceX Dragon cargo spacecraft. The experiment will measure the temperature of plants on Earth to better understand how much water they need and how they respond to stress.

On-Orbit Status Report

USOS Extravehicular Activity (EVA) #49: Today Drew Feustel (as EV-1) and Ricky Arnold (as EV-2) exited the Joint Airlock at 8:30am CDT to perform US EVA #49. Egress was delayed for about 1.5 hours due to issues with suit leak checks that were ultimately cleared. The primary goal of today’s EVA was to install the Node 3 External Wireless Communications (EWC) Antennas and associated cables, Remove and Replace (R&R) the Camera Port (CP)-8 External Television Camera Group, and retrieve the Port 1 Radiator Beam Valve Module (RBVM) Flex Hose Jumpers. All of the prime tasks were completed and the CP8 functions, including External High Definition Camera, were successfully checked out. The N3 EWC system will be checked out at a later date after the internal components are installed. The crew was also able to conduct Pump/Flow Control Subassembly (PFCS) Jumper Set up in preparation for a future USOS PFCS Relocate EVA and perform preparatory tasks on the Pump Module stowed on External Stowage Platform (EXP)-2. The Phased Elapsed Time (PET) for the EVA was 6:10.

Space Station Remote Manipulator System (SSRMS) Operations: Ground robotic specialists have started to walkoff the SSRMS from the Mobile Base System (MBS) to the N2 Power Data Grapple Fixture (PDGF) in prep for Offset Grapples training for Dragon. Following the SSRMS walkoff ground specialists will perform a MT translation from worksite 6 to worksite 4.
