It is certain that there won’t be any life on earth once the sun gets burnt out and it starts expanding to form a red giant which will end the earth and solar system. This is estimated to happen in five billion years from now on. But that time is very far from us, so we don’t need to panic right now. Besides, the search for another shelter planet is going on with the rapid development in science and technology. The other thing that we should fear is about the changing climate and unpredictable weathers that we have been facing currently. It has certainly been a time to be serious about the preservation of earth and its atmosphere to keep our human kind alive.
People might have misunderstood the definition of climate change when they see some extreme winters and get confused that there is no such thing like global warming. It is well to be taken into account that the extreme winters and extreme summers are a part of climate change.
Now let us see how the water has escaped into the atmosphere which will be interesting for us in Earth. As ultraviolet radiation from the Sun streams into Venus' atmosphere, it breaks up the water molecules into atoms: two hydrogens and one oxygen atom. Such continuous reaction transformed water to oxygen and hydrogen. These gases could easily escape to the atmosphere. This shows us that ultraviolet rays from the sun are the main reason for the loss of water on Venus. As a reason of ozone depletion, the water on the earth could face the same attack. The current surface of Venus is like a hot oven. It could be such that the surface was similar to ours in the past over there. I hope and wish that our earth will never be an hot oven. Let us preserve our earth and let preserve ourselves.
South Korea has lost contact with its Naro-1 rocket, just 137 seconds after take-off. Officials believe the rocket exploded.
Korea Aerospace Research Institute (KARI) and Khrunichev State Research and Production Space Center had hoped to use a Naro-1, South Korea's first carrier rocket, to launch a STSAT-2B satellite.
South Korea had postponed the launch on Wednesday due to problems with the rocket's fire extinguisher system. Science Ministry spokesman Pyun Kyung-bum said, "We expect that it will be difficult to launch today".
The rocket lifted off from Goheung's Naro Space Centre at 1701 (0801 GMT) today. The rocket apparently exploded 137 seconds after launch, when a flash was seen from an on-board camera and communication was lost. The loss of communication occurred when the rocket had achieved an altitude of around 70 kilometers (43 mi). Television cameras captured a white speck, presumably part of the rocket, falling into the sea.
Analysts say the failure is a setback for South Korea. If it had been successful, it would have been the first Naro-1 launch to reach orbit. The launch cost South Korea an estimated US$400 million, and if successful, would have launched a satellite called the STSAT-2B into orbit. The satellite was designed to examine climate change and its effects.
The incident is seen as a major setback for South Korea's space program, which had been aiming to become the 10th country to achieve the capability to launch satellites, and the fourth Asian country, after China, Japan, and India. A successful launch would have helped South Korea to become a player in commercial space launches, an industry valued at around US$250 billion. Since 1992, South Korea has launched 11 satellites from overseas sites with foreign-made rockets.
