What is the difference between crewed and uncrewed space missions?
Crewed technologies, such as spacecraft, have astronauts on board. Astronauts are people who pilot spacecraft or complete missions aboard spacecraft. Uncrewed technologies carry scientific instruments that collect data. These data are sent back to Earth, where scientists analyze them.
Why do scientists send both crewed and uncrewed missions into space?
Some experts have argued that scientists can learn almost all they want to know about the solar system and outer space by using uncrewed, mechanized space probes. Such probes can be designed to carry out most of the operations normally performed by humans at much less cost and with little or no risk to human life.
What is meant by space mission?
plural space missions A journey, by a manned or unmanned vehicle, into space for a specific reason (normally to gather scientific data)
How many unmanned space missions are there?
1,000 uncrewed missions
How many astronauts have died in space?

Can you smell in space?
