OKB-1

Mars 1

Mars 1, launched by the USSR in 1962, was the first probe on a successful trajectory to Mars. It held 61 communication sessions, gathering interplanetary space data. On March 21, 1963, contact was lost at 106 million km due to a faulty valve in the attitude control system , which prevented the antenna from pointing to Earth.

Mars 2MV-4 No.1 (Sputnik 22)

The Soviet Mars 2MV-4 No. 1 probe (Sputnik 22) failed on October 24, 1962, when its Blok L upper stage exploded in LEO due to a seized staged-combustion turbopump. Its debris triggered a false ICBM attack alarm in Alaska, averted via vector tracking during the height of the Cuban Missile Crisis.

Mars 1M No.2 (Korabl 5)

The Soviet probe Korabl 5 (1M No. 2) was destroyed on October 14, 1960, during its launch to Mars after a catastrophic third-stage (Block I) failure at T+290 seconds. A liquid oxygen leak froze the kerosene in the turbopump, preventing ignition and forcing a suborbital re-entry over Siberia.

Korabl 4 (Mars 1M No. 1)

Korabl 4, launched by the Soviet Union in October 1960, was the first probe designed to perform a flyby of Mars. The mission failed during its ascent phase due to vibration and resonance issues in the upper stages of the launch vehicle, preventing it from reaching Earth orbit.

Aeolus

The Aeolus orbital mission (2028), structured through a public-private partnership between NASA and Relativity Space under a Space Act Agreement, will deploy the innovative DWTS radiometer to continuously map Mars' winds and three-dimensional thermal profiles. Utilizing the Terran R heavy launcher and an onboard AI data center, this meteorological mission will mitigate atmospheric density risks for future crewed landing systems following the loss of the MAVEN probe.

ExoMars Rosalind Franklin Rover (EXM-RFM)

The ExoMars Rosalind Franklin mission is an ESA-led initiative, with NASA participation, whose main objective is to search for signs of past or present life on Mars. The rover features a drilling system capable of reaching a depth of 2 meters to extract samples protected from ionizing radiation. Its launch is scheduled for October 2028 aboard a Falcon Heavy rocket, with a planned landing in Oxia Planum.
