hi
The main difference - is size ! With a crewed space vehicle, you have to make it big enough to accommodate the people, and include their life-support systems, propulsion etc. With an unmanned probe - it only needs to be big enough to house the instrumentation and power (batteries & solar panels).
Missions with humans on board (i.e. the Crew).
I think it might be because probes are cheaper and just in case something goes wrong, it would not end up resulting in loss of life. (Just an opinion though.)
Gemini 5, crewed by commander L. Gordon "Gordo" Cooper and pilot Charles "Pete" Conrad, was the first spacecraft to use fuel cells rather than batteries for electrical power.
Sometimes the obvious answer is the right one. In general computers can break, malfunction and develop faults. Humans have a level of intelligence that computers and machines just can't have, so sending people into space is useful because they have senses like touch and can repair machines or pilot spacecraft. But, human life is sacred, there's (as you can understand) quite a risk associated with space travel. Humans are designed to live on earth; space is an unnatural habitat for us. If not careful, people could die on space missions etc.

Manned missions allow for real time interaction with the environment instead of waiting for sent commands to be processed, and confirmation returned. But manned missions require expensive, large habitable environments and support systems to keep the astronauts alive.
because it was written in australia in the outback
yes

Fossil fuel is spelt correctly...
The first manned mission to the moon was Apollo 8 and was crewed by Frank Bormann (commander) Jim Lovell, and William Anders, and was designed to reach the moon, orbit and then return, in order to test equipment and to look for landing sites. The first manned mission designed to land on the moon was Apollo 11 and was crewed by Neil Armstrong (commander and the first to walk on the moon), Edwin ('Buzz') Aldrin, and Michael Collins.
Humans have not left outer space. The International Space Station is still crewed.
The cast of Crewed - 2013 includes: Chris Alvarado as Tommy Julie Dixon Jackson as Helen Evelyn Edwards as Theresa Courtney Merritt as Farah Lizzie Peet as Kelly Kirk Robinson as Andrew Connie Shiro as Jojo Dean Weichel as Del
Nope. It was Hugh Laurie who crewed in th 1980 Boat Race.
