"The BIB system is released from the vehicle by an automated launch and recovery system to an operational low altitude appropriate for the application and can provide critical detection capabilities for several miles. Once deployed to the operational altitude, the vehicle can proceed on its mission through any terrain with the BIB system fully functional at altitude. Following completion of a mission, the BIB system is designed to quickly and automatically be recovered while the lifting gas is retained in the BIB self-contained helium storage system. The envelope can then be re-packaged inside the weather sealed crate, the vehicle is able to move on to its next destination, and the BIB system may be re-deployed."
According to the PR, the lifting gas (not sure if it's helium) will be recovered:

IMO Helium is recoverable and scrubable (spell checker says that isn't a word). I haven't seen our WSGI folks say they clearly can so I will only say it is theoretically possible and there are many good practical reasons to do it.
