A destructive asteroid is coming towards the Earth. Such news often makes headlines. But the reader is not moved by this news. Because, asteroids in space often run into each other. Some of them hit the Earth. But what if the asteroid that is coming can be intercepted before it hits the Earth? Surely it is beneficial for humanity. Such an incident has been done by the American space research agency NASA. The American space research center NASA has conducted an experiment to save the world from asteroids in the future.
Their Dart spacecraft was launched 10 months ago to target an asteroid. At 11:14 p.m. (GMT), the spacecraft crashed into the asteroid. "We have entered a new era. An era where we will have the ability to protect ourselves. No dangerous asteroid will be able to hit us," said Lori Glaze, director of NASA's Planetary Science Division.
Live footage from the spacecraft and the response from NASA's ground control team was broadcast live. The camera captured a close-up of the asteroid just seconds before the collision. The spacecraft hit the asteroid at speeds of 14,000 miles per hour (22,500 kilometers per hour). This is the first time such an experiment has been conducted. Now scientists will examine the results.
A few weeks ago, a small satellite, LysiaCube, broke away from DART. It passed close enough to take pictures of the asteroid after the spacecraft crashed into it.
The collision scattered rocks and other debris. Glaze said, "This is where science begins. Did the asteroid change its trajectory?" The mission cost $325 million. This is the first attempt to change the position of something in space using kinetic energy.
Dress rehearsal
There is no asteroid, comet or any other object near the Earth yet. According to NASA, there is nothing that can collide with the Earth. However, scientists warn that more than one such object may be seen. Scientists now have the option that when such an asteroid or comet comes, scientists can change its trajectory.
The second option is to try to break them up in space, so that the impact of the smaller pieces will not be as severe.
