It is a bit of a misnomer to refer to 25,000 mph as the velocity needed to "get into space". If I am not mistaken, "space" is the region approximately 60 miles or so above sea level. So, if you pass this point, you are "in space" but 25,000 mph not required. You can simply plot a ballistic trajectory to this point in space and parachute back to earth. This is precisely what the Gemini program was in the 60s.
However, in order to orbit the planet at the minimally viable altitude of 100 miles above sea level, a velocity of 17,500 mph is required.
In order to escape earth's gravity and transit to another planet, the minimum speed is 25,000 mph.
