Viking 1
Viking 1 was the first of two spacecraft (along with "Viking 2") sent to Mars as part of NASA's Viking program. On July 20, 1976, it became the second spacecraft to soft-land on Mars, and the first soft lander to successfully perform its mission. (The first spacecraft to soft-land on Mars was the Soviet Union's Mars 3 on December 2, 1971, which stopped transmitting after 14.5 seconds.) "Viking 1" held the record for the longest Mars surface mission of days (over 6¼ years) or Martian solar days, until that record was broken by "Opportunity" on May 19, 2010.
Thunderbirds machines
A metallic-blue spacecraft that made the first manned landing on Mars. "Zero-X" first appeared in the first "Thunderbirds" feature film, "Thunderbirds Are Go", and subsequently in the first episode of "Captain Scarlet and the Mysterons". It is assembled hours prior to launch and consists of 5 parts: The MEV (Martian Exploration Vehicle), the main fuselage, "Lifting Body 1" and "2", two wing-like structures loaded with thruster packs and also incorporate landing gear at the ends, and the reflective Nose Cone, which is a large metallic nose which attaches to the MEV.
