No one knows what went wrong with Mars Polar Lander and scientists still hope for a miracle.
America's Mars Polar Lander was supposed to touch down on 3 December, 1999.
On December 3rd 1999, a spacecraft called Mars Polar Lander (MPL) was supposed to touch down near the red planet's southern pole.
The board took a close look at Mars Polar Lander to ensure that it would not encounter unexpected difficulties of its own.
Besides, the Mars Polar Lander came to grief with that system.
One result was that an unlaunched craft similar to Mars Polar Lander was tucked away in a clean room while the agency had a rethink.
Nasa has reacted angrily to the allegation that it knew the Mars Polar Lander (MPL) mission would fail because of a design flaw in the craft's braking thrusters.
Meanwhile, there have also been concerns over Mars Polar Lander.
Nasa spokesman Don Savage said they were not clear about what caused the Mars Polar Lander to disappear as it approached the Martian surface and rejected the earlier claims of a cover-up.
"Before, we could hardly make out dunes there, " said Rich Zurek, project scientist for the Mars Climate Orbiter and Mars Polar Lander, set to arrive at the planet in September and December, respectively.
Lim admits that the recent loss of both the Mars Polar Lander and Mars Climate Orbiter may have affected favourable public opinion, which is what the project needs most if the dream of seeing astronauts on the Red Planet is ever to be realised.
"This analysis suggests that it is not very likely that the December 1999 Polar Lander will be found, " the Web site for the Mars Orbiter Camera concluded.
