Carrier and lander are now in a solar orbit. On March 6, 1974, Mars 7 failed to go into orbit about Mars and the lander.Mars 7 - USSR Mars Orbiter/Soft Lander - 4,650 kg - (August 9, 1973) Lander returned atmospheric descent data, but failed on its way down. On March 12, 1974, Mars 6 entered into orbit and launched its lander.Mars 6 - USSR Mars Orbiter/Soft Lander - 4,650 kg - (August 5, 1973) Imaging data for the Mars 6 and 7 missions. Mars 5 entered into orbit around Mars on February 12, 1974.Mars 4 arrived at Mars on February, 1974, but failed to go into orbit due.River and channel like features were discovered. The first hi-resolution images of the moons Many of the scientific experiments were delayed At the time of its arrival a huge dust storm was This was the first US spacecraft to enter an orbit aroundĪ planet other than Earth. Mariner 9 arrived at Mars on Novemand was placed into orbit.Mariner 9 - USA Mars Orbiter - 974 kg - (-1972) It made measurements of surface temperature and atmospheric composition. The Mars 3 orbiter returned data until August,ġ972. The lander was released andīecame the first successful landing on Mars. Mars 3 arrived at Mars on December 2, 1971.Mars 3 - USSR Mars Orbiter/Soft Lander - 4,643 kg - (May 28, 1971) The first human artifact was created on Mars. ItĬrashed-landed because its braking rockets failed- no data was returned and The Mars 2 lander was released from the orbiter on November 27, 1971.Mars 2 - USSR Mars Orbiter/Soft Lander - 4,650 kg - (May 19, 1971) In addition, over 200 pictures were taken. Surface and atmospheric temperature, surface molecular composition, and pressure Mariner 7 arrived at Mars on August 5, 1969, and passed within 3,551 kilometers.Mariner 7 - USA Mars Flyby - 412 kg - (March 27, 1969) Of the surface and atmospheric temperature, surface molecular composition,Īnd pressure of the atmosphere. Kilometers of the planet's equatorial region. Mariner 6 arrived at Mars on February 24, 1969, and passed within 3,437.Mariner 6 - USA Mars Flyby - 412 kg - (February 24, 1969)

Zond 2 - USSR Mars Flyby - 996 kg - (November 30, 1964) To be composed of carbon dioxide in the range of 5-10 mbar. It returnedĢ2 close-up photos showing a cratered surface. Mission provided the first close-up images of the red planet.

Mariner 4 arrived at Mars on Jand passed withinĦ,118 miles of the planet's surface after an eight month journey.

Mariner 4 - USA Mars Flyby - 260 kg - (November 28, 1964- December 20, Marinerįor more information about the Mariner missions. Solar panels did not open, preventing flyby.
