"Clearly the team is getting more frustrated, certainly, and more tense about all of this,' operations manager Richard Cook said late Sunday.

Another failed mission will put NASA under more scrutiny. The program lost the Mars Climate Orbiter in September because of a math error. The estimated cost of the Polar Lander program is $165 million, which is actually cheap in terms of space projects. The Climate Orbiter is part of the new line of cheaper, faster, better spacecraft. But now it seems that NASA may be ahead of its time.

To make matter worse, the two probes aboard the Lander have also failed to contact Earth. Scientists say that even if the probes were working, they would no longer be sending signals because the batteries should be dead. The probes were supposed to crash into Mars and burrow into the ground to look for water.

But scientists aren't giving up just yet. They will continue for the next few days to establish contact with the Polar Lander. There is still a small chance the spacecraft is intact.

The Mars Polar Lander didn't make contact with Earth after landing on Mars. NASA says the spacecraft is probably lost. Scientists don't know what caused the spacecraft to fail.

Also, the 2 probes sent to crash into the Red Planet and search for water have not made contact. Scientists think they probably broke apart when they crashed.

Scientists are still hoping the Polar Lander will send out signals. Keep your fingers crossed!
