Oct. 21, 1966

The Department of Interior submitted to NASA performance specifications for EROS, including spacecraft requirements.

Feb. 1967

NASA began in-house Phase A feasibility studies of an Earth Resources Technology Satellite (ERTS), which were completed in Oct. The studies concluded that ERTS was feasible using existing state-of-the-art equipment; launch could take place in 1970.

Mar. 1967

NASA Headquarters authorized the Goddard Space Flight Center to study the feasibility of automated spacecraft systems for ERTS.

Apr. 28, 1967

NASA requested inputs from industry for its Phase A ERTS study; 29 companies responded and about half of them made presentations at Goddard starting the next month.

However, in January 1975, President Gerald Ford overrode OMB's decision. ERTS C was included in the FY 1976 budget. Project planners now called for a September 1977 launch.

Aug. 1974

The Senate conducted hearings on bills that would establish a separate Office of Earth Resources Survey Systems within NASA and an Earth Resources Observation Administration within the Department of Interior to administer the operational phase of ERTS. NASA Administrator James C. Fletcher argued that it was too early in the program to separate development and operations; NASA opposed the bill.

Sept. 18, 1974

In further hearings on establishing operational offices for ERTS, an OMB official testified that it was too early to set up such a management structure for the still experimental satellite.

Nov. 25, 1974

Senator Frank E.
