The moon appears to warp the minds of some men. Despite putting men on the moon in 1969 America seems determined on re-enacting the space race, this time pitting its efforts against those of the Chinese. Now a Russian company claims it could develop a system to exploit the moon’s natural resources and potentially relocate harmful industries there. This is lunacy.
Russia certainly has great prowess in space. In its former guise as the centre of power in the Soviet Union it launched the first man-made satellite in 1957. In a spectacular follow up, Yuri Gagarin became the first person in space in 1961. Another triumph came in 1968 when the Russians sent a spaceship to orbit the moon with turtles aboard, returning it and its living cargo safely to Earth. An unmanned Russian spacecraft also landed on the moon ahead of the first manned landing by the Americans. Even after Neil Armstrong took his one small step, Russia has proved its superiority in keeping people in space stations orbiting the Earth. The Russian Soyuz rocket is a mainstay of satellite launches and would be used to rescue astronauts should any accident befall the International Space Station.
Head of the spacecraft manufacturer that helped achieve these Russian successes, this week boasted that his rockets could be used to industrialise the moon. So why were his remarks greeted with such scepticism
One reason for the cynicism is that the idea is absurd. A United Nations treaty passed in 1967 bans potentially harmful interference with the Earth’s original satellite and requires international consultation before proceeding with any activity that could disrupt the peaceful exploration of space, including the moon. A second problem is that landing on the moon has proved beyond the budget of any state other than America and of any private company to date.
In fact one of the best hopes for investment comes from space tourism. On Saturday April 7th, the fifth such holidaymaker entered space aboard a Russian Soyuz rocket. Charles Simonyi, an American software developer, paid $25m for his ten-day stay at the International Space Station. The next holiday destination is the moon. The tour operator that organised the first five packages is offering two tickets to orbit the moon for $100m each. Launch would be aboard a Soyuz spacecraft. But the Soyuz system was designed in the 1960s and has been on the verge of retirement for many years. Unfortunately the Russian authorities have postponed indefinitely the development of a successor. Thus the claim of the industrialisation of the moon is unlikely to succeed.

There are many reasons of the tidal action which is a very complicated phenomenon involving many factors all of which must be considered to predict tide in any one place at any one time. The alternate rise and fall of the surface of the seas and the ocean is mainly caused by the attractive force of the moon alone. When the attraction is great, the tide is high; and conversely when the attraction is minimal, the tide is low. Between the high and the low tide is a period of a little over six hours, being called during its rise a flood tide, and during its fall an ebb tide.
The sun also exerts its effect on the tide, being a lit fie less than half as much as the moon, although its mass is so much greater. When the moon and the sun are horizontal, the highest high tide occurs and when they are vertical the lowest low tide takes place.
The wind also plays an important part in the modification of the normal rise and fall of the tide. Thus these factors affect each other, either detracting or adding to the attractive forces to add or subtract from the weight of the tide. But the tides still move inexorably on, rising twice a day, getting a little later each day and posing a problem of correctly predicting their heights and lows.

It can be concluded from this article that the attraction of the sun is（）

A:more than half that of the moon B:more than that of the moon C:more than twice that of the moon D:half that of the moon

A plane can't fly to the moon because ______.

A:the moon is 240 kilometer far away B:we don't know where it is C:it can't fly without air D:there is no air on the moon

The National Aeronautics and Space Administration (NASA) has announced plans to return people to the moon by 2018. "And this time," according to a NASA press release, "we’re going to stay."
NASA wants to make a new spaceship for the missions using parts from the Apollo program, which first took people to the moon in 1969, and the space shuttle. NASA says the new Crew Exploration Vehicle (CEV) will be "affordable, reliable, and safe."
The CEV will be able to hold four astronauts. The plan is to have the CEV dock(对接)in space with the lunar lander—the vehicle astronauts will use to land on the moon—which will be launched separately into space. The CEV will then travel to the moon and all four astronauts will walk on the moon.
The first moon missions are expected to last up to seven days. Exploration and construction of a moon base will be the astronauts’ top priorities (最优先考虑的事) . NASA hopes to have a minimum of two moon missions a year starting in 2018. This will allow for quick moon base construction, constant scientific study, and training for future missions to Mars.
What is new in NASA’s plan to return to the moon by 2018

A:People will land and remain on the moon. B:Equipment will be carded and installed there. C:More CEVs will be made regularly. D:A special device will be used in landin
