The U.S. space Agency plans to launch a probe, equipped with a solar sail. He will leave earth orbit and go to the distant asteroid due to the pressure of sunlight. Like the ships of the discoverers of the 15th century, in 2018, a small space probe will unfurl the sail and start a journey to a faraway asteroid, marking the beginning of a new phase in space exploration.
The idea of using solar sails for space flight was proposed almost a hundred years ago, Soviet rocketry pioneer Friedrich Zander. It was based on the fact that Photons of light can exert pressure on the illuminated surface, giving him his momentum. Therefore, if you expand behind the ship a giant mirror, his speed will gradually increase without using fuel.
However, the first experimental devices were established only at the very end of the twentieth century. This is because space sailboats should be very easy, and their embodiment in life became possible only after the emergence of a truly compact electronics. Continue reading
Future space tourists are already thinking about what it would be like to have sex in zero gravity. However, scientists hasten to cool the ardor of the lovers: sex in space could harm the health.
Future space tourists are already thinking about what it would be like to have sex in a vacuum. However, scientists hasten to cool the ardor of lovers.
According to biologists, to conceive a child in extraterrestrial environments will most likely not succeed. Space hostile to earthly love, the scientists shrug. Moreover, they say that sex in space could cause irreparable harm to human health. These words are confirmed experimentally. However, I was involved in a potentially dangerous study not people, and plants.
Their cells are damaged when the gravity changes, proved the researchers. In particular, when too high or too low gravity to the negative impact of exposed pollen tube is the vegetative cell of the male zarostka in flowering plants. Gravitational changes are not the best way affect its development and functioning.
In addition, the space environment is threatened intracellular circulation of the plant. Continue reading
Only three years left until that happy moment when the first space tourist from Earth will be in lunar orbit. To launch travelers into space will be from Baikonur.
The British company “Excalibur Almaz” announced at the meeting in London of the European conference on space tourism, a detailed plan of the tour to the moon. In 2015 the first space tourists “Excalibur” will be transported to the launch vehicle “Soyuz-FG” from Baikonur first on earth space station and then a lunar orbit. There are travelers from a distance of 1000 kilometers will be able to look at the dark side of earth’s satellite. All the journey will take eight months.
But flight preparation begins long before the start. The tourists intending to explore the moon at close range, will not only have to pay for a ticket $ 150 million, but also undergo special training. I will not fly professional astronauts to control the spacecraft have their own.
Interestingly, to launch tourists to the moon “Excalibur Almaz” will be the good old Soviet engineering. The company bought in Russia four used capsules and two space stations “Almaz”. Each capsule is placed three tourist, and to use it 15 time. So “Excalibur Almaz” will be able to send to the moon 180 space tourists, and then, suddenly, a new ship will come up, or will buy in Russia more of the older capsules. Continue reading
