Viking 1: the story

  1. Viking 1

    NASA Project Viking · 1975 – 1982

    In July 1976, humanity landed on Mars. After four failures by previous missions, Viking 1 descended through thin Martian air and gently touched down on Chryse Planitia, opening a window onto an alien world.

  2. Titan IIIE-Centaur launch

    20 August 1975 · Cape Canaveral LC-41

    A 160-foot Titan IIIE rocket roared off Launch Complex 41 carrying the combined 3,500-kg orbiter and lander into space, beginning an 11-month voyage across 500 million kilometers of interplanetary void.

  3. Touchdown on Chryse Planitia

    20 July 1976 · 11:53:06 UTC

    Aeroshell discarded, supersonic parachute deployed, and three throttleable hydrazine engines guided the 572-kg lander down into Chryse Planitia (the Golden Plain) at 2.4 m/s. It settled stably onto three aluminum footpads.

  4. The first picture from Mars

    Sol 0 · 25 seconds after landing

    Just 25 seconds after engine shutdown, Camera 2's nodding mirror scanned line by line down Footpad 2. When the signal reached Pasadena 19 minutes later, scientists cheered: clear ground, fine red dust, and intact landing struts.

  5. A red sky and volcanic plains

    Sol 1 · 21 July 1976

    Camera 1 scanned a 300-degree panorama across Chryse Planitia. Instead of the expected blue sky, Mars showed a butterscotch salmon atmosphere saturated with suspended airborne dust, scattered with wind-carved volcanic basalt boulders.

  6. Scooping the soil for life

    Sol 8 · 28 July 1976

    The robotic collector arm extended 3 meters and dug the first robotic trenches on Mars. Soil was dumped into three automated biology chambers. When tagged nutrients were injected, radioactive carbon gas surged—sparking a 30-year debate.

  7. Six years of daily weather reports

    1976 – 1982 · 2,245 Martian Sols

    While Viking 2 fell silent in 1980, Viking 1 kept working. Powered by SNAP-19 plutonium generators, it broadcast daily meteorology, seasonal dust storms, and atmospheric pressure trends across three full Martian years.

  8. The fatal command

    11 November 1982 · Sol 2245

    During an antenna software update beamed from Earth to optimize battery charging, a memory pointer address collided with the high-gain antenna steering code. Viking 1 pointed its dish away from Earth, into empty space, and never answered again.

  9. Thomas Mutch Memorial Station

    In December 2006, the HiRISE camera on MRO spotted Viking 1 resting quietly on Chryse Planitia, its backshell, heat shield, and parachute resting within a mile. Renamed for imaging team leader Thomas Mutch, it stands as humanity's first home on the Red Planet.

The end

Thank you, Viking 1.
