As the Soyuz MS-12 that will carry the Expedition 59 crew to the International Space Station Thursday was erected on the launch pad at the Baikonur Cosmodrome in Kazakhstan, Expedition 58 resumed research and routine maintenance after their off-duty day Monday.

NASA astronaut Anne McClain conducted botany work with the VEG-03 experiment, which builds on what scientists have initially learned about harvesting vegetation in space with VEG-01. This time around, testing will demonstrate plant growth with a new batch of crops, including red romaine lettuce, extra dwarf Pak Choi, red Russian kale and wasabi mustard. McClain also spent time on life-support system upkeep in the Kibo lab module and maintenance in the U.S. lab on an EXPRESS rack--hardware integral to providing structural interfaces and support for science experiments with power, data, cooling, water and other items needed for successful operations.

In the Quest airlock, Canadian Space Agency astronaut David Saint-Jacques completed additional prep work for upcoming spacewalks slated for March 22, 29 and April 8 by scrubbing cooling loops and performing leak checks on the spacesuits. After resupplying the Human Research Facility-2 rack, Saint Jacques added input to a questionnaire for Behavioral Core Measures, an investigation that seeks to create a standardized toolkit to rapidly and reliably assess the risk of adverse cognitive or behavioral conditions and psychiatric disorders that could occur with longer space missions.

Meanwhile, Commander Oleg Kononenko from Roscosmos ticked off additional maintenance tasks by cleaning panels in the Zvezda service module and performing fluid transfers to the Progress 71 resupply ship.

On-Orbit Status Report

SBC (Spaceborne Computer) Inverter Replacement: Today the crew replaced the failed Spaceborne Computer-1 power inverter. The inverter was subsequently powered up and showed all green lights. Spaceborne Computer's goal is to run a yearlong experiment of high performance commercial off-the-shelf (COTS) computer systems on the ISS. During high radiation events, they intend to verify if the systems can still operate correctly by lowering their power, and therefore, speed. This research helps scientists identify ways of using software to protect ISS computers without expensive, time-consuming or bulky protective shielding.

Veg-03H Wick Open: As part of the early growth cycle of the plants, the crew performed the wick opening activity. The plant pillows in the Veg-03H investigation contain Wasabi Mustard Green and Extra Dwarf Pok Choi seeds. Organisms grow differently in space, from single-celled bacteria to plants and humans. Future long-duration space missions will require crew members to grow their own food, so understanding how plants respond to microgravity is an important step toward that goal. Veg-03H uses the Veggie plant growth facility to cultivate Extra Dwarf Pak Choi and Wasabi mustard, which are harvested on-orbit.

Extravehicular Mobility Unit (EMU) Loop Scrub: The crew performed ionic and particulate filtration scrubbing and biocidal maintenance on EMUs 3003 and 3008 water cooling loops. Water samples and conductivity readings were also taken from the cooling loops.

Common Communications for Visiting Vehicles (C2V2) Firmware Update: The crew installed the C2V2 contingency software load cable to both comm units in order to allow loading of Firmware Revision 3 to each unit. Ground teams proceeded with a nominal firmware load on both units. This software update corrects several minor issues identified during on-orbit operations, including false indications of stale transceiver telemetry, Very High Data Rate (VHDR) signal acquisition, and User Datagram Protocol (UDP) port assignment.
