The Columbus budget was trimmed slightly by canceling the smaller $145-million Eureca B platform. When the complete phase C/D proposal (fixed price) was delivered end 1989 by the prime contractor MBB- ERNO it turned out that the costs were much higher than expected by ESA. same computers used for all three elements, video and comms units identical to station equipment). For development cost saving and optimization of spares provisioning during the operational phase commonality was foreseen between the flight configurations and to the space station (e.g. Since the initial plans, numerous studies and proposals were made. Hermes would dock with the man-tended free-flyer to retrieve microgravity experiments. NASA approved the MTFF although it would require additional communications, docking facilities, data processing and other Station resources. The MTFF element would be serviced by the Hermes mini-shuttle launched atop the Ariane 5, flying periodically to the station for maintenance and reconfiguration. The estimated costs of the MTFF alone were $160вЂ“180 million in 1986. The entire Columbus package (MTFF, APM, PPF) was expected to cost $3.56 billion including launch and utilization. An unmanned Polar Platform (PPF) for remote sensing and data return.An Attached Pressurized Module (APM), as a manned space station component.A Man-tended Free-Flyer (MTFF), as a space station element.Initially the Columbus program included three flight configurations: The Columbus program was intended to supplement NASA's Space Station Freedom. Like the Multi-Purpose Logistics Modules (MPLMs) and the Automated Transfer Vehicle (ATV) resupply craft, Columbus traces its origins to Europe's Spacelab. Aspects of the program were later realised in the Columbus science laboratory attached to the International Space Station (ISS).Д®SA's Board of Directors approved the Columbus program in 1985. The program ran from 1986 to 1991, was expected to cost $3.56 billion including launch and utilization, and was cancelled while still in the planning stage. It consisted of a Columbus module docked to a service module containing solar power collectors, communications and other services.

The Columbus Man-Tended Free Flyer ( MTFF) was a European Space Agency (ESA) program to develop a space station that could be used for a variety of microgravity experiments while serving ESA's needs for an autonomous manned space platform.
