Collection Item Summary:

Initiated in 1970, the Improved Tiros Operational Satellite (ITOS) system was a series of six satellites that provided, for the first time, day-to-day, routine weather observation from space for the benefit of the general public.

This educational poster, prepared to accompany the inauguration of the ITOs program, highlights the importance of this new capability to monitor the Earth's weather. Aimed at school-age audiences and hobbyists, the poster also reflects NASA's interest in stimulating public interest in its programs.

Note the special attention the poster gives to the "momentum wheel". This innovation was new to ITOS and enabled the spacecraft to point its cameras and other instruments constantly at the Earth, improving its observational capabilities.
