Lunar Roving Vehicle
In the late 1960s, NASA began a series of missions to the moon. On the 21 ____________ three missions the astronauts explored on foot only a few hundred meters around then spacecraft, but on the last three missions, they used a small electric car which allowed them to see and do much more on their short visits.
The Lunar Roving Vehicle (LRV) was an electric car which had a top 22 ____________ of 8 mph, and allowed the astronauts to visit sites five miles away from their landing, and to 23 ____________ samples from a much wider area to help scientists get a better 24 ____________ of the moon’s surface.
The LRV had to be 25 ____________ to the moon in the bottom part of the spacecraft. A camera was set up in the LRV so that NASA could control remotely 26 ____________ the Earth, allowing them to 27 ____________ the astronauts as they explored the moon’s surface in the LRV.
NASA plans to go 28 ____________ to the moon from the year 2022. This time they aim to explore thousands of miles of the surface, staying for months at a time. Right now, NÁSA is working on new ideas for moon cars in which astronauts can live and 29 ____________ for up to two weeks. They will be able to sleep in the cab, and there is a separate compartment where they can put on the space 30 ____________ to go exploring on foot.

People have been talking about UFOs for ages. Millions of normal people keep saying that they were caught and taken into UFOs.
The first case was in the 1950s when George Adamski said a UFO had taken him to the far side of the moon. Another case took place in 1961, when an American couple, Betty and Barley Hill, were chased by a UFO while they were driving home one night in New Hampshire. The couple stopped to observe the UFO through binoculars. To escape from it, they took the back roads and arrived home two hours later.
Fourteen years later, in 1975, one of the most shocking events happened in a small town in Arizona, when a woodcutter called Travis Walton disappeared with a blue-green light from a flying saucer under his teammates’ eyes. Five days later, the missing woodcutter returned home and said, T woke up on the UFO and found myself among strangers with no hair and half-formed face. They put a mask over my face, and I fell asleep again. 1 remembered nothing else until I awoke in the forest where I had been caught.’

A UFO (Unidentified Flying Object) is any object flying in the sky which cannot be identified by the person who sees it. Sometimes the object is investigated. If people cannot figure out what the object is after an investigation, it is called a UFO. If they figure out what the object is, it can no longer be called a UFO because it has been identified.
Even though UFOs can be anything, people can use the word UFO when they are talking about alien spacecraft. Flying saucer is another word that is often used to describe an identified flying object.
Studies estimate that 50-90% of all reported sightings are identified later. Usually 10-20% are never identified. Studies also show that very few UFO sightings are hoaxes (people trying to trick other people). Most UFOs are actually natural or man-made objects that looked strange. 80-90% of UFOs are identified as one of three different things: (a) astronomical causes (for example: planets, stars, or meteors); (b) aircraft; and (c) balloons. 10-20% of UFOs are other causes, such as birds, clouds, mirages, searchlights, etc.

I sometimes dream about meeting an alien from Mars. He looks very strange.
