CAPE CANAVERAL, Fla. -- Tom Simon of NASA's Commercial Crew Program, or CCP, talks to aerospace industry representatives during a pre-proposal conference to inform prospective companies about the recently released request for contract proposals and updates to the certification requirements for crewed missions to the International Space Station, or ISS. The two-phase certification process, called Certification Products Contract, or CPC, will enable NASA to eventually purchase service missions to fly astronauts to and from the ISS. Simon will serve as chair of the CPC Evaluation Team that will come together to identify, research and ensure that the selected companies can comply with NASA's contract requirements.
