NASA launches vehicle to hit an asteroid to change its orbit-ezone.hk-Technology Focus-Technology Cars

Although it is rare for an asteroid to hit the earth, if it happens, it may cause a devastating disaster. The United States Space Agency (NASA) launched the “Double Asteroid Redirect Test” (DART). It launched a space vehicle on the 23rd. It is expected to hit an asteroid 10 months later to test whether it can make the asteroid derailed.

  • Launched the Falcon 9 rocket from the Vandenberg Space Base in California, carrying the “Dual Asteroid Diversion Test” spacecraft into the air
  • It is expected to hit the Dimorphos asteroid at a speed of about 6.7 kilometers per second between September 26 and October 1 next year.
  • The mission hopes to shorten the orbit of Dimorphos by 10 minutes, but a reduction of 73 seconds is considered a success

The launch mission was carried out by SpaceX. At 10:21 pm on the 23rd, US time, the Falcon 9 rocket was launched from the Vandenberg Space Base in California, carrying the “Double Asteroid Diversion Test” spacecraft into the sky.

Ten days before the asteroid is approaching, DART will release a miniature space vehicle equipped with a lens to record the impact process and transmit the image back to Earth. The ground-based astronomical telescope will measure the speed and orbit change of the asteroid after the impact.

The spacecraft is about the size of a vending machine. It is expected to hit the asteroid Dimorphos at a speed of about 6.7 kilometers per second between September 26 and October 1 next year, hoping to slightly change its orbit.

This task hopes to shorten the orbit of Dimorphos by 10 minutes, but it is considered a success if it is shortened by 73 seconds. The entire mission is expected to cost 330 million U.S. dollars.
