Robots, such as the Curiosity rover, are very beneficial for missions that require precise and repetitive measurements or manoeuvres, as well as missions that last a considerable amount of time. Humans, on the other hand, are much better suited to tasks involving decision-making, or those that require constant adjustments and intervention from scientists.
Sending both spacecraft and humans into space is a worthwhile endeavour since we can learn a great deal of information from both, which can later help us in our goal to send people beyond Earth. By sending humans into space we can gain unique insights into the workings of the human body, especially the parts that are masked by gravity here on Earth, something that we’ve learned more about from astronauts living aboard the International Space Station (ISS).
