Viking 1 var en amerikansk rymdsond som utforskade planeten Mars. Rymdsonden bestod av en kretsare och en landare. Rymdsonden sköts upp den 20 augusti 1975, med en Titan IIIE-raket från Cape Canaveral Air Force Station. Kretsaren gick in i omloppsbana runt Mars den 19 juni 1976. Landaren landade i Chryse Planitia på Mars den 20 juli 1976.[3] Farkosten var den första att lyckas landa på planeten.
Kretsaren
Farkosten gick in i omloppsbana runt Mars den 19 juni 1976. I februari 1977 passerade den marsmånen Phobos. Den fungerade fram till den 17 augusti 1980, då man valde att stänga av farkosten. Den hade då tagit fler än 57 000 bilder av planeten.[3]
Landaren
Landaren landade med hjälp av raketer och skyddades vid inträdet i Mars atmosfär av en värmesköld. Den drevs av en radioisotopgenerator och fungerade fram till den 11 november 1982, då man under en programvaruuppdatering förlorade kontakten med rymdsonden.[3]

Mars Hubble.jpg
NASA's Hubble Space Telescope took the picture of Mars on June 26, 2001, when Mars was approximately 68 million kilometers (43 million miles) from Earth — the closest Mars has ever been to Earth since 1988. Hubble can see details as small as 16 kilometers (10 miles) across. The colors have been carefully balanced to give a realistic view of Mars' hues as they might appear through a telescope. Especially striking is the large amount of seasonal dust storm activity seen in this image. One large storm system is churning high above the northern polar cap (top of image), and a smaller dust storm cloud can be seen nearby. Another large dust storm is spilling out of the giant Hellas impact basin in the Southern Hemisphere (lower right).

Viking 1 launched aboard a Titan IIIE rocket August 20, 1975 and arrived at Mars on June 19, 1976. The first month was spent in orbit around the martian planet and on July 20, 1976 Viking Lander 1 separated from the Orbiter and touched down at Chryse Planitia.
