Dubai, United Arab Emirates (CNN) – The International Astronomy Center explained, on Monday, the experiment that will be carried out by NASA, which aims to study the interception and change of the path of an asteroid heading towards Earth.
In the statement, a copy of which was received by CNN in Arabic, the center said: “For the first time in history, scientists will conduct an experiment at dawn tomorrow, Tuesday, September 27, to change the course of an asteroid, in order to study the effectiveness of changing the path of an asteroid that will collide with Earth and pose a threat to it. In this regard, NASA launched its probe The space named DART, an acronym for the binary asteroid redirection experiment, where the probe was launched on board a space rocket on November 24, 2021 AD, heading to an asteroid called Dimorphos, a small asteroid with a diameter of 160 meters orbiting a larger asteroid with a diameter of 780 meters called Didymo. Didymos), which means “twin” in Greek.
The center added: “The experiment aims to change the orbit of the small asteroid by colliding with the probe, so currently the small asteroid revolves around the large asteroid once every 11 hours and 55 minutes. This asteroid does not pose any danger to Earth, but was chosen for astronomical considerations, including that it is easy to monitor by ground-based telescopes after the collision, so that it can be monitored by a large network of ground-based observatories to determine whether the experiment succeeded or not. If this experiment is successful, this technology becomes one of the solutions to confront a dangerous asteroid heading towards Earth.”
And the center continued in its statement: “The probe took a period of 10 months to reach the asteroid, and the collision will occur at dawn on Tuesday 27 September at 03:13 am UAE time, and the speed of the probe at the moment of impact will be 22,000 kilometers per hour, and then the asteroid will be 11 miles away. The diameter of the small asteroid is 100 times the diameter of the probe, and the speed of the asteroid is expected to change by only 0.1%. The asteroid is now shining by 14.5, and it is not possible to be certain what we will see from Earth at the time of the collision, so estimates range that we will notice a significant change on The luminosity of the asteroid at the time of the collision means that we will not notice anything. Scientists will need several days or weeks after the collision to monitor and study the movement of the new small asteroid to know whether the experiment is successful or not.”
The center pointed out that it “communicated with the supervisor of this mission, so that the Astronomical Seal Observatory will be one of the global observatories that participate in the photometric analysis of the asteroid after the collision to assess the extent of the success of the experiment, and indeed the participation of the observatory was accepted as one of the participating observatories from the UAE. Where the Astronomical Seal Observatory will, God willing, will By monitoring the asteroid at the moment of impact, in addition to making photometric observations after that, and sharing them with the mission supervisors. The collision can be followed live on NASA TV.”
