Generally, soft moon landings have required the use of retro-rockets. These are small rocket engines designed to slow the descent of the spacecraft. On Mars, inflatable airbags have been used. Several teams are now competing to land rovers on the moon as part of the Google Lunar X-Prize...it will be interesting to see if any of them intend to use novel new approaches to achieve soft landings.

How is it possible to land on the moon?
If you're asking how you personally can do it, that's really beyond the scope of what we can cover here. If you're asking in general... by a thorough and rigorous application of the principles of science and engineering (and finance, because all that science and engineering is going to cost billions of dollars).
How fast did Apollo spacecraft travel when going to the moon?
The Apollo spacecraft traveled approximately 25,000 miles per hour (40,000 km/h) on its journey to the moon. The spacecraft had to reach this high velocity to escape Earth's gravitational pull and reach the moon.
How do you land safely on the moon?
You descend in lunar module, a special space ship designed to work in the lesser (compared to earth) gravitational pull of the moon. The LM fires it's rocket engine to slow down the descent of the craft until it lands. The LM is in two pieces. The lower part lands on the moon. The upper part fires it's engine and lifts off the moon and goes up to link with the command module orbiting the moon for the return journey back to earth.
What is the conspiracy behind Apollo 11?
Look there was no conspiracy here about the Apollo 11 spacecraft, as it really did land on the moon and then returned safely back to the earth. we must remember that there were thousands of people watching the launch of the spacecraft. So it was really a big success.
What are some of the problems that needed to be overcome in order for NASA to be able to land men on the moon and return them safely?
The primary concern of any moon landing is the high velocity involved that arises from the effects of gravity. In order to go to any moon, a spacecraft must first leave the gravity well of the Earth.

Why must spacecraft be completely sealed?
Space is a vacuum and would suck all the air out of the spacecraft not to mention freeze the interior of it.
How fast did Apollo 8 travel?
The speed of an Apollo spacecraft is hard to answer because there are many answers available. The best question would ask something like "What was the maximum speed?", or "what was the average speed during the translunar or transearth phase?" The problem is that the speed of spacecraft was constantly changing. In order to break out of Earth orbit and reach the moon, an object must travel approximately 24,000 miles per hour. The Apollo spacecraft did just that. However, they didn't maintain that speed. Once they were out of orbit, they simply coasted the entire distance to the moon. Breaking out of Earth orbit does not mean breaking free from Earth's gravity though. The Earth was constantly pulling on the spacecraft, slowing it down. Eventually, the spacecraft got close enough to the moon that that moon's gravity had a stronger effect than the Earth's gravity, pulling the Apollo module forward, causing the module to speed up. With that in mind, we can provide the speed of Apollo 8 at various events: At translunar injection, Apollo 8 was traveling at 35, 505.41 ft/sec, or 24,208 mph. When the spacecraft entered the moon's sphere of influence (when the action of the moon's gravity became stronger than the action of the Earth's gravity on the spacecraft), it had slowed down to 3,261 ft/sec, or 2,223 mph. When the spacecraft reentered the Earth's atmosphere after returning from the moon, it was traveling at 36,221 ft/sec, or 24,696 mph.
Where must the moon be to appear crescent?
The moon must be on the left or the right of the moon, where the sun only shines on a part of the moon. Showing only a crescent of the moon.
What must happen for a new moon to occur?
For a new moon to occur the moon must be between earth and the sun
During a solar eclipse, what phase must the moon be in?
During a solar eclipse, the moon must be in the new moon phase.
How tell someone you have herpes?
You must softly break the news to her, and you both must be alone.
Where is the secret crop land in harvest moon ds cute?
The Special Field is in a cave behind the Waterfall. To get there you must remove the large boulders blocking the path. To do that you must get the Sword at the bottom of the Second Mine.
