Why did the mission to Mars fail?
445480
If you are talking about the Mars Climate Orbiter, it is because the manufacturer specified the thrust of the attitude jets in pounds but the navigation team though the numbers were in metric units. This caused the navigation team to make incorrect calculations which resulted in the space craft arriving at Mars orbit insertion too low and entering the atmosphere instead of going into orbit.

Still human being cannot determine simpler and safer way to get to the local orbit, let alone Mars together with long haul voyages, nowadays human's intellect is only good to sell the Moon's 'lands' for the future-based villas and finding idiotic 'smiles' on the Martian surface, unfortunately.   \ncheers

They already do. Do you mean, inter-planetary flights? And if so, how far away? Pluto? Nuh-uh. Mars? Not necessarily a bad idea. It all depends on how far away the mission crew is to be sent, and how long the duration of the journey is to be. If the crew were to find themselves in an emergency, they would of course have to be more resilient and capable of quick thinking because Houston would not be of any help to them.

Apollo 13 was a space flight mission that went awray.  While in space, some faulty electronics sparked some O2, thus causing no oxygen and electricty to come to the service module, they slingshoted around the mooon and landed back to earth.  The 2nd catrophse in the Manned space program

If we waited for every problem on earth to be solved before we explore Mars, or advance any other scientific project of importance, we'd never do anything. Ideally, the poor health system in America would be resolved AND space exploration would advance. (and pigs might fly :-)

They decided that the evidence was inconclusive - it was possible that it was, but it turned out that it was possible that the sample could have been contaminated or compromised at some stage, or that geological or mineral activity could conceivably have created the same features seen - it seems probable that this is the case. \nSo they can't ever decide whether the rock is actually a fossil of Martian life, but they are absolutely certain that it is not PROOF of Martian life - a disappointing but rigorously scientific conclusion.

No - (let me guess all you people who think we did will give me a thumbs down !!!!)\n\n- My old pocket calculator has more power than the computers used 'to get to the moon'\n- photographic evidence\n- the camrea evidence\n- if they got there, why did they then just 'stop'\nand not sent many other missions there / set up a research station etc\n\nI do, however, think that they DID get there years later - after all what would happen if a space craft passed over and there was no moom buggy, footprints & flag.\n\nIQ ? HAH !!!! IQ does not measure important things like common sense, creative thinking, social skills etc etc\n(and YES I do know mine - its above average I just choose to dismiss it)

Well, what do you mean by accomplished? There are some ongoing missions that have been launched but certainly aren't done. Two of them this year have been: The New Horizons spacecraft was launched and is on its way to Pluto; also, the Mars Reconnaissance Orbiter went into orbit. These are probably two of the biggest on the NASA table. Hope this helps.

Because our government failed you.

The factors were that MIR, the first true space station, was getting old and it was time to replace it. In its time, MIR provided answers to many questions regarding health in space. The ISS, was designed as the first step towards getting to Mars, with much of the necessary research being performed on ISS. It is still living up to what we put it up there for: mixing purer medicines, advancing knowledge of space, and a possible lead on a cure for diabetes.

Deffinitely, we need something from the space program to be PROUD of again.  Since we lost Russian competition, we've squandered our time in space.  I say it's time to do these things, not because they're easy, but because they're hard!

I think the Viking probes had seismometers for detecting volcanic activity, but they found nothing I believe. Mars has been inactive, dry and probably lifeless for billions of years.

Short answer:\n\nUnmanned space exploration is more cost effective, efficient, and lower risk. We can always build new robots, and we can send them over longer distances than people (at least initially).\n\nManned space exploration would have a better chance to capture public support. A human mind in control of a space mission might see or intuit things a computer guided sensor might not, and it might react creatively in an emergency. Ultimately, we'll place more value on manned spaceflight. We've already put robots on Mars, but the first human on Mars will be a much bigger deal. Sending humans through space safely seems to be one of the goals of space exploration.

That controlled descent was never planned and therefore very impressive.   It was a very succesfull mission.  The descent might prove that the unplanned part of the mission could be the most valuable if we ever have to land something on another rock in a hurry...

some say that the apollo missions to the moon were fake so that america could win the space race. also because their is really no interset on the moon for us except moon rocks. we can study the craters from earth. NASA and other space researchers in the world are planning missions to mars, and unmanned space explorations of other planets.
