Actually not the same amount...not even close. You only have to lower
the perigee such that you reenter on the proper trajectory whereas
going up you have to get into a circular orbit

How do you get rid of all the velocity than builds up as you decend
through near vacuum and your energy of postition becomes energy of
motion?
