Identify the benefits that your space mission might provide for modern society. Explore the possibility of connecting your space mission with satellites that are already gathering information as they orbit Earth.
I don't understand what does this mean?
Hey, in orbit there is no air around you and therefore no air pressure. You must maintain approximately atmospheric pressure inside if manned. If unmanned, you still must make sure nothing blows up when the outside pressure goes to zero.
There is no nice layer of air to insulate you from the sun or to slow radiation from you into space if in the shade (behind a planet or on the side of your system away from the sun) Therefore the side facing the sun will get lots of infrared radiation and the side away will get very cold. Equipment will swell or shrink and boil or freeze.
In orbit your centripetal acceleration balances your gravitational attraction so net effect is weightless. There is no "down". Everything must be secured or it will drift around.
How would a space mission help people on earth?
OK, Now I understand. thanks Ms. Sue & Damon for the help!
Identify any challenging conditions that you may encounter on your mission; this may include near vacuum conditions, extreme temperatures, and microgravity. Explain how you will overcome these challenges with the design of your spacecraft.
