How fast did the Appollo 11 fly?

I would like to know in MPH|||Apollo The Apollo 11 spacecraft was launched from Cape Canaveral, Florida on Wednesday, July 16, 1969. It accelerated to a speed of 25000 miles per hour in order.

鈥? years - traveling at the speed of light (not taking into account pit-stops for coffee).








鈥f course it depends on how fast the object is traveling. In one of the NASA Space Shuttles, about 76,526 earth years (38,263 earth years one way). 1 light-year is 5.8 trillion miles and the maximum speed of a NASA Space Shuttle is 17,500 miles per hour.





The fastest unmanned space craft traveled 157,000 mph. At that rate, there and back would take only 8,500 earth years. So if you were a Mesopotamian farmer in 6,500 BC, you'd be getting home right about now.








鈥ot only would this depend on the speed you are traveling, but it also depends on your point of view: If you were to be inside a spacecraft traveling at the speed of light, it would take you 2 years, but it would seem as if no time at all had elapsed!





鈥t our current level of technology, and allowing for no fundamental breakthroughs in physics but allowing for reasonable engineering development along known lines, the fastest spacecraft that we are currently capable of building would be an Orion Nuclear Pulse Rocket. Wikipedia has a good general description at the link below, but the basic concept is that we build a REALLY BIG spacecraft - perhaps twice the mass of a current US Navy aircraft carrier - and set off nuclear bombs behind a gigantic bowl and shock absorber. Such a device ought to be able to attain about 10% of the speed of light, but it would take about 2 years to reach that speed, and two years to slow down and stop. We would NEVER send out such a ship one light-year out and come back; we'd keep going to a potentially habitable star, but IF we needed to, we could probably do it in about 100 years.

You burn the rocket at one end to gain enough velocity, and then you coast the rest of the way. If you're flying to the moon, the earth's gravity is constantly slowing you down, until you reach a point where the moon's gravity is stronger, then you speed up again. If you're flying back to the earth, you continue to slow down until the earth's gravity becomes stronger than the moon's, and you "fall" all the way back t the earth. Imagine that you coast up a hill--you slow down until you reach the top, and then speed back up down the other side.





To shorten that whole paragraph, it means they weren't traveling at a constant velocity.





Their highest speed outbound was 24,235 mph, right after the third stage burn that sent them on the way to the moon. Their fastest speed coming back was 24,678 mph, at the moment they began the "Entry Interface" with the earth's atmosphere.





If you could travel at the highest outbound speed for the whole trip, it would take 27,670.8 years. At the highest inbound speed, it would only take 27,174 years
