Yes, to get out of Earth's gravity, you need to achieve "escape velocity"'which is around 17000 mph. The force you would need would be proportional to the mass of your spaceship and that value varies sharply as you burn fuel. The other consideration is your acceleration. If you exceed about 5 gs the astronauts could blackout, and really more than 1 g over time would be uncomfortable. Once you figure out those design parameters, solve F=ma (or more precisely, F = d/dt(mv)) to get the result you desire.

This is all off the top of my head, no searching.

She just needs dick? Is that the smartest thing you could come up with? Hey dick, can you imagine for a fraction of a second that the teen girl has a point? Never heard of Mariner 10 (1973) and Messenger (2004)?

10 mln km from the Sun the temperature is 800 degrees Celsius. 20 mln km - the temperature is 600. If we want to send a space station as close as 30 mln km from the Sun, we need to build a spaceship that can function in 350 degrees Celsius. How about a shield that can work for some time in 600? Imagine what kind of discoveries about the Sun and Solar system can be made during such a flight.

Shame on you, smart-asses.

The Parker Solar Probe and the Solar Orbiter are both on missions to the sun. While they aren’t attempting to land on it, they are going to get quite close to it.
