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 [!DSTAG SYMBOL ID=ch0001 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0002 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0003 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 1988 (USSR) Goal- Investigate Mars’ moon Phobos. Lost contact mid-way due to erroneous command sent by controllers.

 

Phobos 2 [!DSTAG SYMBOL ID=ch0004 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0005 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 1992 (NASA) Some pictures prior to arrival, but lost upon orbit insertion. Fuel line froze leading to explosion?

 

Mars 96 [!DSTAG SYMBOL ID=ch0006 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 1996 (Russia) Huge complex mission with multiple orbiters & landers. Didn’t even reach Earth orbit.

 

Nozomi [!DSTAG SYMBOL ID=ch0007 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0008 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0009 DIMS='[[6,1,-3,0,-1],[8,1,-3,0,0],[10,2,-4,0,0],[],[],[],[25,4,-9,0,0]]' CHARID=ch0 INSUBSUPER=0/] 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 [!DSTAG SYMBOL ID=ch0010 DIMS='[[5,1,-3,0,-1],[8,1,-3,0,0],[10,1,-4,0,0],[],[],[],[25,3,-10,0,0]]' CHARID=ch1 INSUBSUPER=0/] 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
