ISS Update: Logistics Reduction and Repurposing -- 09.27.12
› Watch video (Part 1)
› Watch video (Part 2)

Public Affairs Officer Brandi Dean interviews Sarah Shull, Deputy Manager for the Logistics Reduction and Repurposing project in the Advanced Exploration Systems program. Shull discusses the Logistics to Living tests from the Deep Space Habitat mockup at Johnson Space Center.

Experts are studying secondary ways to use items after their primary use has expired during a deep space mission. The International Space Station is resupplied by cargo ships, which are then filled with trash and deorbited over the Pacific Ocean for a fiery destruction. Crews on a deep space mission will have fewer resupply options and fewer ways to get rid of trash they produce. So it’s important that NASA find innovative ways to recycle trash and reuse gear in preparation for these future missions.

An example of converting an item no longer being used would be designing cargo bags so that they could be turned into a sleeping bag or a partition for privacy between modules, once they’ve been emptied of cargo. Trash could be heat-melted for sterilization and compacted for space efficiency and, potentially, used as radiation shields.

ISS Update: JAXA Small Satellite Orbital Deployer -- 09.26.12
› Watch video

ISS Update Commentator Pat Ryan interviews Dr. Victor Cooley, Exp. 33/34 Lead Increment Scientist, about the JAXA Small Satellite Orbital Deployer (SSOD) demonstration.

The SSOD was launched to the International Space Station aboard the Kounotori3 H-II Transfer Vehicle, or HTV-3, in July.

During the SSOD demonstration, five small satellites will be launched into orbit using the station’s robotic arm. The satellites are initially housed inside of the station and then loaded into the SSOD by Flight Engineer Aki Hoshide. Hoshide will then put the SSOD into an airlock, which is depressurized and exposed to the vacuum of space via an automatic door. Flight controllers will then use the robotic arm to grapple the SSOD in the airlock and move it out away from the station so the satellites can be deployed.

ISS Update: ATV-3 ReEntry Breakup Recorder -- 09.24.12
› Watch video

ISS Update Commentator Pat Ryan talks with Dr. William Ailor, Principal Investigator for the ReEntry Breakup Recorder (REBR) for The Aerospace Corporation. Ailor talks about capturing data as Europe's ATV-3 cargo craft re-enters the Earth's atmosphere for a fiery destruction over the Pacific Ocean. Experts want to predict the destructive effects of a spacecraft re-entering the atmosphere for safety and cost reasons.

REBR, which is a device similar to a cell phone inside a heat shield, will be exposed to the fiery re-entry and record a variety of data such as acceleration, pressure and temperature. REBR will make an Iridium telephone call to transmit the data after it is thrown clear of the disintegrating spacecraft. The REBR is designed to survive re-entry but not impact.

REBR has previously been used on three other cargo craft. Data was successfully captured from the atmospheric re-entry of Japan's HTV-2 and HTV-3 vehicles. During an ATV-2 re-entry experiment the REBR did not capture data. Engineers are exploring whether it was the design of the REBR, its placement in the ATV-2 or the violent nature of the re-entry itself.
