I'm creating a personal list of soviet missions to the Moon, Mars and Venus with dates and times for special events. So far, I got the following for the Mars missions:

Mars 1 - Target: Mars
Time Date Event
n/a 01.11.1962 Spacecraft launched
n/a 21.03.1963 Communications ceased (Probably due to failure of the spacecrafts antenna orientation system)
n/a 19.06.1963 Distant Mars flyby (193,000 km)

Mars 2 - Target: Mars
Time Date Event
16:22:44 UTC 19.05.1971 Spacecraft launched
n/a 27.11.1971 Mars 2 enters orbit around Mars (1,380 x 24,940 km)
n/a 27.11.1971 Mars 2 lander seperated from orbiter
n/a 27.11.1971 Mars 2 lander malfunctioned (Parachute did not deploy)
n/a 22.08.1972 Mars 2 Orbiter completed its mission after 362 Orbits

Mars 3 - Target: Mars
Time Date Event
15:26:30 UTC 28.05.1971 Spacecraft launched
n/a 02.12.1971 Mars 3 enters orbit around Mars
09:14:00 UT 02.12.1971 Mars 3 lander seperated from orbiter
13:49:00 UT 02.12.1971 Mars 3 lander enters Martian atmosphere
13:52:10 UT 02.12.1971 Mars 3 lander touched down on Martian surface
13:52:25 UT 02.12.1971 Mars 3 lander transmission stopped for unknown reasons
n/a 22.08.1972 Mars 3 orbiter completed its mission after 20 orbits

Mars 4 - Target: Mars
Time Date Event
19:30:59 UTC 21.07.1973 Spacecraft launched
n/a 10.02.1974 Mars Flyby (2,200 km)
n/a 10.02.1974 Mars 4 didn't reach orbit due to a retro-rocket failure

Mars 5 - Target: Mars
Time Date Event
18:55:48 UTC 25.07.1973 Spacecraft launched
15:45:00 UT 12.02.1974 Mars 5 enters orbit around Mars (1,755 x 32,555 km)
n/a n/a Mars 5 orbiter fails due to loss of pressurization in the transmitter housing after 22 orbits

Mars 6 - Target: Mars
Time Date Event
n/a 05.08.1973 Spacecraft launched
n/a 12.03.1974 Mars 6 lander seperated at a distance of 48,000 km from Mars
n/a 12.03.1974 Mars 6 enters orbit around Mars
09:05:53 UT 12.03.1974 Mars 6 lander enters the Martian atmosphere
09:08:32 UT 12.03.1974 Mars 6 lander parachute opened
09:11:05 UT 12.03.1974 Contact to Mars 6 lander has been lost (Lander possibly hit surface with 61 m/s)
n/a n/a Mars 6 orbiter completed its mission?

Mars 7 - Target: Mars
Time Date Event
n/a 09.08.1973 Spacecraft launched
n/a 09.03.1974 Mars 7 lander seperated 4 hours too early (Lander misses Mars by 1,300 km)
n/a 12.03.1974 Mars 7 orbiter and lander entered heliocentric orbits
n/a n/a Mars 7 orbiter completed its mission?

I'm missing some timestamps for several events. Does somebody know precise dates and times for each mission events? Maybe even some additional events? I hope that my english is not too worse , I don't need it so often. Your help would be very appreciated.

I have found the Deep Space Chronicle to be a treasurehouse of information about all deep space missions from 1958 to 1999.
