ESSA.....U.S., satellite, meteorological, similar in configuration to the TIROS satellites for the United States ENVIRONMENTAL SCIENCES SERVICES ADMINISTRATION (ESSA). (U.S. Weather Bureau became part of ESSA) The U.S. Weather Bureau which included the Weather Service, was part of the U.S. Department of Agriculture. However a new Administration was created in 1965, called the United States Environmental Sciences Services Administration (ESSA). The Weather Bureau became part of ESSA on 13 July, 1965. The objective of the satellite program remained the same, to establish a global weather satellite system. The ESSA satellites were considered operational satellites vs earlier satellites which were test and research satellites (e.g. TIROS, NIMBUS). New weather satellites launched after 1965 were officially named ESSA, after they were launched and operating correctly in orbit. However, in the queue in 1965 were two TIROS satellites, TIROS 11 and 12. Since they were launched after 1965, they were renamed ESSA 1 and ESSA 2 once in orbit. They were the last TIROS satellites launched from Cape Canaveral. ESSA 1was placed into a 689 x 818 mile (1100 x 1300 km) polar, sun synchronous orbit, with a period of 100 minutes. ESSA 2 as well as all the remaining ESSA satellites were placed into a higher 1400 mile (2240 km) polar orbit with a period of 114 minutes. The newer satellites were named TIROS OPERATING SATELLITES (TOS), while being constructed. Once in orbit and operating properly, their names were changed to ESSA 3 through 9. All the ESSA satellites weighted about 300 lbs (136 kg), the same as the TIROS.
Newer technology was used in ESSA 2 - 9. The satellites contained:
- Automatic Picture Transmission (APT) for delayed or direct readout to ground stations, which allowed pictures of local cloud conditions to be downloaded to inexpensive ground stations, i.e., special radios or fax machines and/or
- the Advanced Vidiocon Camera System (AVCS) for higher resolution daylight coverage, both of which were from the NIMBUS satellites. The television cameras had 800 line resolution, covering 4,000,000 square miles with a 2 mile resolution. The ESSA satellites were shaped like the TIROS and operated similar to TIROS 9. The life of the satellites varied from 465 days for ESSA 4 to 2644 days with ESSA 8. All the ESSA satellites were built by RCA.

- Structure and Evolution of the Universe.
The first EXPLORER satellite, EXPLORER 1. The Explorer program today, has four main areas: Medium-class Explorers (MIDEX), Small Explorers (SMEX), University-class Explorers (UNEX)/Student Explorer Demonstration Initiative (STEDI), and Missions of Opportunity. Each of these areas has several future satellite Missions planned. Medium-class Explorers or Mid Explorer Satellites (MIDEX) - are investigations not to exceed $140 million (in Fiscal Year 1998 dollars) total cost to NASA. NASA Intends to launch one MIDEX mission per year. Only one satellite, MAP, is currently funded. Under the MIDEX program is the MAP Satellite. Small Explorers (SMEX) - are investigations not to exceed $71 million (in Fiscal Year 1998 dollars) total cost to NASA. It is NASA's intent to launch one Small Explorer mission per year. 2 satellites are funded, HESSI and GALEX. University-class Explorers (UNEX)/Student Explorer Demonstration Initiative (STEDI) - are investigations not to exceed $7.5M (real year dollars) total cost to NASA. University-class Explorer Missions will be launched by a variety of low cost methods. Initially, one launch per year is anticipated. A long term goal is to achieve multiple launches per year for this class of Explorer Missions with a substantially lower cost per mission. Currently, three satellites are funded, CHIPSat, CATSAT, and IMEX. Missions of Opportunity - are investigations characterized by being part of a non-NASA space mission of any size, but having a total cost to NASA that is typically under $21 million (in Fiscal Year 1998 dollars).

- Astronomical Search for Origins and Planetary Systems,
- The Sun-Earth Connection, and
- Structure and Evolution of the Universe.
