Holiday on the Moon?
A People first visited the moon in 1969, when Neil Armstrong made ‘a giant leap for mankind’. Between 1969 and 1972, a total of 12 men walked on the moon. After the moon landings, the focus of space travel turned to making reusable spacecraft and building the International Space Station.
B Construction has not yet begun, but some experts predict that there will be a hotel on the moon in the next 50 years. Virgin Galactic is already planning tourist flights to orbit the Earth, and may be able to touch down on the moon to deliver tourists one day.
C The big challenge is cost. Lots of people want to visit space, but at the moment, a ticket for even a short journey is more than most normal people can afford. The other challenge is training and fitness. Astronauts require at least six months of training to be prepared for the physical effects of rocket travel. Most people don’t have the time to prepare.
D A company called Bigelow Aerospace has developed space stations that are inflatable, like balloons. Each station could be used as a home-on-the-moon for up to 18 people. The rooms wouldn’t be large, but they would have a great view of the Earth.
VIII. Read the passage and then decide whether the statements are true (T) or false (F).
The International Space Station - the manned satellite - has constantly circled the Earth in low orbit up to now. Since the first permanent crew moved in on 2 November 2000, 220 people representing 17 countries have come and gone. Most of those astronauts have been Americans on the space shuttle flights to deliver the equipment, food and other supplies.
Russia has sent the second largest number of people, with Canada and Japan tied for third. At least one American and one Russian have been on board at all times.
The ISS orbits 240 miles above the planet at 17,150 mph and can often be seen by the naked eye. The complex has grown from three to 13 rooms and the current structure has a mass of nearly 450 tons. More than 26,500 meals have been served, 1,760 experiments carried out and 189 spacewalks undertaken, according to NASA. The 189 spacewalks have been undertaken to build and maintain the space station.
The most important experiment, according to Commander Scott Kelly, was about keeping humans alive in space.
NASA administrator, Charles Bolden, called the 15-year milestone in 2015 ‘a remarkable moment’. He added, ‘It has taught us about what’s possible when tens of thousands of people across 15 countries work together with the shared goals.’
1. The International Space Station started working on 2 November 2000. ________
2. People of different nationalities have worked on the ISS. ________

8. The achievements of the ISS are to make thousands of people in many
countries collaborate with the same purposes. ________

Neil Armstrong was the first to step onto the Moon.

During the stay of more than twenty-one hours on the Moon’s surface, the astronauts found no rain or wind at all. The Moon was like a desert with plains, mountains, and valleys.

Exercise 6: Choose the letter A, B, C or D to answer these following questions
A new study published in the journal Science shows definitive evidence of organic matter on the surface of Mars. The data was collected by NASA's nuclear-powered rover Curiosity. It confirms earlier findings that Mars, the Red Planet once contained carbon-based compounds. These compounds – also called organic molecules – are essential ingredients for life as scientists understand it.
The organic molecules were found in Mars's Gale Crater, a large area that may have been a watery lake over three billion years ago. The rover encountered traces of the molecule in rocks extracted from the area. The rocks also contain sulfur, which scientists speculate helped preserve the organics even when the rocks were exposed to the harsh radiation on the surface of the planet.
Scientists are quick to state that the presence of these organic molecules is not sufficient evidence for ancient life on Mars, as the molecules could have been formed by non-living processes. But it's still one of the most astonishing discoveries, which could lead to future revelations. Especially when one considers the other startling find that Curiosity uncovered around five years ago.
