NASA May Extend BEAM’s Time on ISS 3-5 Years


The original plan called for engineers to robotically jettison BEAM from the space station following the two-year test and validation period, allowing it to burn up during its descent through Earth’s atmosphere. However, after almost a year and a half into the demonstration with positive performance, NASA now intends to continue supporting BEAM for stowage use and to allow Bigelow Aerospace to use the module as a test-bed for new technology demonstrations. A new contract would likely begin later this year, overlapping the original planned test period, for a minimum of three years, with two options to extend for one additional year. At the end of the new contract, the agency may consider further life extension or could again consider jettisoning BEAM from the station.

Using the space inside BEAM would allow NASA to hold between 109 to 130 Cargo Transfer Bags of in-orbit stowage, and long-term use of BEAM would enable NASA to gather additional performance data on the module’s structural integrity, thermal stability and resistance to space debris, radiation and microbial growth to help NASA advance and learn about expandable space habitat technology in low-Earth orbit for application toward future human exploration missions. Given that the volume of each Cargo Transfer Bag is about 1.87 cubic feet (0.53 cubic meters), use of BEAM for stowage will free an equivalent space of about 3.7 to 4.4 International Standard Payload Racks, enabling more space in the ISS for research.

This is an odd announcement. They talk about this like it’s both already decided and still up in the air, and they say the contract extension could come “later this year.” Why not wait a few weeks-to-months to announce this?

However odd the announcement, this would (will?) be great. It adds a massive amount of storage space and opens up a ton of room for work on the ISS. Coupled with the increased crew size that Commercial Crew will bring, this sets the stage for a very productive next few years on the ISS.
