The average age of menopause in the United States is 51, but it is considered perfectly normal for a woman to go through it at any time between the ages of 35 and 59, says Lila Schmidt, MD, a reproductive endocrinologist in private practice in San Diego. âAnything above 35 is not premature,â she says.ccording to the National Institutes of Health, if you start your periods early (before age 12) and go through menopause late (after age 55), you have an increased risk for breast cancer.
In space, the rocket and the fire push off each other. Yes, if a rocket is on the ground, and fuel ignites under it, then some of the upward pressure on the rocket could come from the ignited fuel pushing off the ground.
Depends on how much fuel your rocket can carry for the upper stages. The Saturn V used in the Apollo missions (which is the most powerful rocket used to date) fired the upper stages off LEO on July 16th, 1969 (of Apollo 11). The crew performed Lunar orbit insertion on July 19th. Of course, after the initial TLI burn from LEO, the spacecraft coasted all the way to the Moon.
