NASA Space Station On-Orbit Status 26 May 2017 - CubeSats Deployed

More CubeSats were ejected from the International Space Station this week to explore the Earth's upper atmosphere. Meanwhile, the Expedition 51 crew trained for a crew departure and cargo craft arrival.

NanoRacks, a private company with facilities on the space station, deployed a total of 17 CubeSats over two days this week from a satellite deployer outside the Japanese Kibo lab module. The tiny satellites will orbit Earth for up to two years observing Earth's thermosphere and studying space weather.

Two Expedition 51 crew members are returning to Earth June 2 completing a 196 day mission in space. Soyuz Commander Oleg Novitskiy and Flight Engineer Thomas Pesquet practiced their descent today in their Soyuz MS-03 spacecraft. The duo are expected to land in Kazakhstan next Friday at 10:10 a.m. EDT.

The Dragon resupply ship, from SpaceX and loaded with brand new science experiments, will launch June 1 and arrive at the station June 4. NASA astronaut Jack Fischer will be at the robotics controls commanding the Canadarm2 to reach out and grapple Dragon. He and station Commander Peggy Whitson familiarized themselves today with the Dragon capture procedures and lighting conditions inside the cupola.

On-Orbit Status Report

NanoRack Cubesat Deployer (NRCSD) #12 Cubesat Deploys: The remaining 8 of 17 NRCSD #12 CubeSats were successfully deployed from the ISS today. All are a subset of the QB50 constellation of CubeSats provided by countries from around the world. The constellation studies the upper reaches of the Earth's atmosphere over a period of 1 to 2 years. The QB50 satellites conduct coordinated measurements of the thermosphere, a poorly studied and previously inaccessible zone of the atmosphere. The project monitors different gaseous molecules and electrical properties of the thermosphere to better understand space weather and its long term trends.

NanoRacks Module-55: The crew swapped samples in the NanoRacks Module 55 which is mounted on the front of NanoRacks Platform-1 in the JEM. This investigation researches why bacteria are more virulent and grow more rapidly in space. NanoRacks Module 55, also known as NanoRacks - National Design Challenge - Centaurus High School - The Effects of Simulated Gravity on Bacterial Lag Phase in a Microgravity Environment (NanoRacks-NDC-CHS-Bacterial Lag Phase), studies the bacterial lag phase, a delay period before the start of exponential growth, which is much shorter in microgravity than it is on Earth. The experiment uses a centrifuge to simulate gravity, comparing microgravity and simulated-gravity Escherichia coli (E. coli) cultures to determine whether microgravity itself causes changes in bacterial growth.

Electrostatic Levitation Furnace (ELF): The crew replaced the ELF Ultraviolet Lamp bulb and set up the ELF gas supply hose and gas bottle. The ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the Electrostatic Levitation method. With this facility, thermophysical properties of high temperature melts can be measured, and solidification from deeply undercooled melts can be achieved.

Soyuz 49 (49S) Nominal Descent Drill: The 49S Crew performed a nominal Soyuz Descent Drill in preparation for their return to earth next week. Soyuz undock is scheduled for June 2, 2017 at 5:48 AM CDT with landing occurring at 9:10 AM CDT.

Extravehicular Mobility Unit (EMU) Suit Maintenance: The crew completed routine maintenance on EMUs 3006 and 3008 including a loop scrub, iodination and a post-loop scrub water sample. Following these activities, EMUs 3006 and 3008 were removed and stowed in the Crewlock and EMUs 3003 and 3010 were installed onto the Equipment Lock EMU Don/Doff Assembly.

On-Board Training (OBT)/Mobile Servicing System (MSS) Operations: Robotics Ground Controllers powered up the MSS in the Hot Backup Configuration and maneuvered the Space Station Remote Manipulator System (SSRMS) into position over the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF) for the start of the SpX-11 Offset Grapples Practice session. Crew members Whitson and Fisher then practiced maneuvering the SSRMS into the grapple envelope of the PMM FRGF. They performed this several times, then performed a final run during which Controllers safed the SSRMS to simulate a failure. The crew recovered by switching from the Cupola Robotic Workstation (RWS) to the Lab RWS and backing the SSRMS away. Following the training session, Controllers maneuvered the SSRMS to the SpX-11 rendezvous park position.

Remote Power Control Module (RPCM) N21B4A_B Trip Status: RPC 2 on RPCM N21B4A_B tripped Thursday night. This RPC powers the Node 2 Audio Terminal Unit (ATU) 1_ Starboard. Node 2 ATU-2_Port is still available for caution and warning tones and audio functionality and is connected (via patch panel) to the starboard Crew Quarters. Review of the 50Hz data did not show any indication of an overcurrent. Ground controllers were able to execute the FET Controller Hybrid (FCH) troubleshooting in an attempt to recover the RPC. The first re-closure attempt was unsuccessful indicating a FCH failure. Approximately an hour after the troubleshooting was attempted, the RPC closed and then re-opened 40 seconds later. Teams believe that this is a new failure signature of the FCH issue and are working a re-closure attempt today. Ground teams will review this new FCH failure signature.
