What are advantages and disadvantages for crewed spacecraft?

Answer 1

First of all, unmanned space flights are a lot less-risky. Even in our advanced civilization space flight is still not a easy feat.

Robotic probes and rovers can operate for a longer period on less energy, they are a lot cheaper, requires no food, no water, no Plumbing and is generally a lot easier to operate.

The disadvantages of unmanned space missions are obvious, six years of exploration of two rovers could be done in 1-2 weeks by astronauts. Astronauts can improvise on the spot, where as the rovers for example has limited movement, and the option for problem solving is limited to the array of equipment specially designed for each little operation.

The rover Spirit have been irrecoverably stuck since 2009 in soft soil. But it is still a great success, operation freely for 1944 days, versus the predicted 92 days.

Answer 2

Although robotics are getting better all the time humans still have an edge when it comes to improvisation and adaptation to unforeseen circumstances. If a mission runs into trouble there are things that can be handled if humans are present that would have been immediate showstoppers for an unmanned flight.

Answer 3

You cannot rely on them properly because they tend to fail. Another disadvantage is that their research wouldn't be as indepth as a humans.

Answer 4

the advantages of using unmanned spacecrafts are that it costs alot less than using manned spacecrafts, and there is a lower risk of some one getting injured or killed

Answer 5

There are good and bad points about manned and unmanned space travel. I think that it should be manned because humans can do more than robots!

Answer 6

They aren't as accurate as manned spacecraft and they tend to break down a lot.

Also, when they break down - they are irretrievable.

Answer 7

• there is less chance of someone dieing or getting hurt.

Answer 8

there are no men in it

Answer 9

This day in age.... none really.
