Document Summary
The human eye has a resolution of about 1/60 a degree. Not enough to see many details when we look at the moon. Looking at the moon with the telescope limited capability due to the atmosphere. Some types of light do not make it to earth"s surface but are absorbed by atmosphere instead (visible light makes it to the ground, but uv rays do not) Performs about 1- times better (resolution wise) than on the ground: 1/36,000 degree. Not good enough to take a photograph of io (jupiter"s moon) To go fast enough to get to orbit launch vehicles are mostly fuel and oxidizer. No air to burn rockets in space, so rockets must bring their own oxygen. Delta iv heavy + parker solar probe. Launch vehicle: 81,500 kg oxygen/fuel: 628,000 kg. New horizons mission travelling to pluto was launched at speed of 58,500km/hr. As you go away from the sun, the suns" gravity pulls away from you, slowing you.
