Seasat was the first satellite designed for remote sensing of the Earth's oceans with synthetic aperture radar (SAR). The mission ended on October 10, 1978 due to a failure of the vehicle's electric power system. The suspicion exists that the satellite was intentionally shut off because the quality and nature of the results obtained alarmed the Pentagon.

Environmental research. The experiments carried were a limb infrared monitoring of the stratosphere (LIMS), stratospheric and mesopheric sounder (SAMS), coastal-zone color scanner (CZCS), stratospheric aerosol measurement (SAM II), earth radiation budget (ERB), scanning multichannel microwave radiometer (SMMR), solar backscatter UV and total ozone mapping spectrometer (SBUV/TOMS), and temperature-humidity infrared radiometer (THIR). These sensors were capable of observing several parameters at and below the mesospheric levels. After 11 years in orbit, three experiments, SAM II, SBUV/TOMS, and ERB, were still functioning successfully. References: 1 , 2 , 5 , 6 .

Conduct of complex investigations on the interaction between the magnetosphere and ionosphere of the earth. Launched under the Intercosmos programme by the USSR in cooperation with the Czechoslovak Socialist Republic, the German Democratic Republic, the H ungarian People's Republic, the Polish People's Republic and the Socialist Republic of Romania. On 14 Nov 1978, Magion, a small Czechoslovak scientific satellite, separated from object 1296. References: 1 , 2 , 5 , 6 , 116 .

Ionospheric, magnetospheric studies. The Czechoslovak satellite MAGION was launched into orbit by the Soviet spacecraft Intercosmos 18. It forms a part of the scientific programme of Intercosmos 18, launched from USSR territory on 24 Oct 1978. MAGION was separated into an autonomous orbit on 14 Nov 1978.
