NASA Space Station On-Orbit Status 14 April 2017 - Computer Hardware and Software Upgraded


NASA Space Station On-Orbit Status 14 April 2017 - Computer Hardware and Software Upgraded.

The three International Space Station residents upgraded computer hardware and software today. The crew is also heading into the weekend preparing for the arrival of a new crew and a new cargo shipment.

Commander Peggy Whitson and Flight Engineer Thomas Pesquet replaced outdated routers this morning with new ones providing expanded capabilities in the station's U.S. segment. Whitson was in the Destiny lab module swapping routers while Pesquet was inside the Harmony module performing the computer maintenance. The router swaps and software updates were done to get ready for the arrival of the next station crew.

Expedition 51 will expand by two crew members when a veteran Roscosmos cosmonaut and a first time NASA space-flier arrive on Thursday. Soyuz Commander Fyodor Yurchikhin and Flight Engineer Jack Fischer will launch aboard the Soyuz MS-04 spacecraft and take a six-hour, four-orbit ride before docking to the Poisk module. The duo will begin a mission expected to last about 4-1/2 months.

Orbital ATK is getting ready to roll out its Cygnus spacecraft loaded with over 7,600 pounds science gear and crew supplies. Cygnus is scheduled to launch Tuesday at 11:11 a.m. and take a four-day delivery trip before being captured by the Canadarm2 and installed to the Unity module.

On-Orbit Status Report

Joint Station Local Area Network (LAN) Version 10.0 Transition: This morning the crew replaced the Edge Routers in the Lab and Node 2. Following the hardware replacement, ground teams began intsalling JSL v10 and configuring the network using the upgraded routers. The previously installed Integrated Station LAN (ISL) Routers were reaching end of life on their flash memory and the new upgrades allow support of gigabit ethernet connectivity which will result in increased network throughput. Checkout of the system by ground teams is in work and proceeding nominally.

S11A_C Remote Power Controller (RPC) 3 Status: Yesterday afternoon, Flight Controllers successfully commanded this RPC closed after a 3rd attempt. Full activation of the Starboard Thermal Radiator (STR) MDM was then successfully performed. This RPC had initially tripped open on Monday as a result of a Field Effect Transistor (FET) Controller Hybrid (FCH) failure.

N21B4B_B RPC 16 Status: This RPC which powers the Node 2 Moderate Temperature Loop (MTL) System Flow Control Assembly (SFCA) Valve was successfully closed yesterday afternoon. Closure of this RPC enables the ability for closed-loop control of the Node2 MTL loop flow. Ground teams are assessing the root cause of this RPC trip which occurred this past Wednesday.
