WASHINGTON -- NASA will host a media teleconference with Associate Administrator for Space Operations Bill Gerstenmaier at 4 p.m. EST, Tuesday, Dec. 23, to discuss the contract selection for commercial cargo resupply services for the International Space Station.

NASA released a Request for Proposal on April 14 for the cargo needs of the space station beyond those supplied by current international agreements. NASA will depend on commercial resupply for reliable, safe and cost effective cargo delivery services to the station.

Reporters who wish to participate must call 202-358-1100 by 2 p.m. on Tuesday for dial-in information. Replays of the call will be available through Dec. 24 by dialing 866-465-2115 and entering the pass code 122308.

The Commercial Resupply Services procurement will include requirements for launch services, orbital rendezvous and berthing with a crewed spacecraft, delivery of internal and/or external cargo, unberthing and deorbit, and disposal or return of internal cargo.
