Failures
Despite all of the wonderful information these spectacular missions have given us, we should not lose sight of the fact that many of the mission have been dismal failures, and there is no reason to believe that the future will not hold many additional failures!
There were a few failures by the USA (Mariner 3 and 8) and numerous ones by the USSR (who fared much better with Venus).
Mars 2
1971 (USSR) The orbiter beat Mariner 9 to be the first human-made object to orbit
Mars. But the severe dust storm prevented it from obtaining images with decent
surface detail. The Mars 2
lander likewise became the first human-made object to reach the surface of
Mars (it crashed).
Mars 3
Lander
1971 (USSR) was the first spacecraft to land softly on the surface of Mars. It failed
after 110 seconds after transmitting a small portion of a picture. The combined
output of images for the Mars 2 & 3 orbiters was 60 picture, compared to
the 7,329 by Mariner 9.
Phobos 1
1988 (USSR) Goal- Investigate Mars’ moon Phobos. Lost contact mid-way due to
erroneous command sent by controllers.
Phobos 2
1988 (USSR)
Some pictures of mars & Phobos. Then lost orientation due to computer
defect, lost power (solar panels…). You can read about the Phobos missions at
the Phobos Home Page or
the Phobos project
Information Page of the NSSDC (National Space Science data Center).
Mars
Observer
1992 (NASA) Some pictures prior to arrival, but lost upon orbit insertion. Fuel
line froze leading to explosion?
Mars 96
1996 (Russia) Huge complex mission with multiple orbiters & landers. Didn’t even
reach Earth orbit.
Nozomi
1998 (Japan) Failed to achieve proper trajectory. 4 years later and added gravity
assists by Earth, correction maneuver in 2003 failed. Project terminated.
Mars
Climate Orbiter
1998 (NASA) Lost during orbit insertion due to navigational error. Compare the
reason for failure given at the previous one with the more ‘sanitized version
given here.
Miles or kilometers?
Mars
Polar Lander
1998 (NASA) Lander & 2 Penetrators (Deep Space 2). Communication lost.
Probably crashed when landing rockets were shut of prematurely. No one knows
the fate of the penetrators.
Beagle-2
2003 (Open University, UK), along with
Mars Express (ESA) reached Mars successfully. Beagle-2, a lander, was the first
experiments since Viking to look for life, failed to establish contact after
landing. Status unknown
