China is focusing on a small non-threatening near-Earth asteroid for a daring try to run into it at excessive speeds and transfer it off its course. The Chinese language asteroid deflection take a look at may occur as early as 2027, in a undertaking just like NASA’s current DART mission.
A current paper within the Journal of Deep Area Exploration revealed new particulars about China’s upcoming planetary protection mission, which can even serve a twin function and probe the traditional house rock for clues relating to its origin.
China first introduced its plans to launch an asteroid deflection mission in late 2022, focusing on asteroid 2019 VL5 with a pair of spacecraft launching in 2025. In line with the brand new paper, nevertheless, China is now focusing on a distinct asteroid, 2015 XF261, with a launch date no sooner than 2027. The goal of the mission might change as China refines its launch window.
Asteroid 2015 XF261 is round 98 toes broad (30 meters) and had a current encounter with Earth when it zipped previous our planet at a distance of 31 million miles (50 million kilometers) on Tuesday, July 9. The near-Earth asteroid routinely passes by the planet twice a yr, with the following flyby on February 21, 2025.
Of the 31,000 near-Earth asteroids which were found, about 2,300 are thought of probably hazardous by NASA. These are asteroids that come inside 30 million miles of our planet. The chosen asteroid for the mission poses no present menace to Earth, however the take a look at goals to show a way of deflecting an area rock ought to one be headed in the direction of our planet sooner or later.
China’s upcoming mission will ship two spacecraft to orbit the asteroid for a interval between three to 6 months. One of many spacecraft is designated to hold out observations to check its measurement, form, composition, and orbit, in accordance with The Planetary Society. Its extra violent twin, the impactor spacecraft, will slam into the asteroid in a high-speed kinetic vitality affect take a look at. The remark spacecraft will monitor the affect, in addition to its aftermath for a interval of six to 12 months.
If this sounds barely acquainted, that’s as a result of NASA pulled off an identical mission not too way back. NASA’s DART (Double Asteroid Redirection Take a look at) mission impacted a small asteroid in September 2022 to nudge it off its orbital course. The mission focused a small moonlet Dimorphos, which was orbiting a bigger house rock referred to as Didymos and it was successful. Previous to DART’s affect, it took Dimorphos 11 hours and 55 minutes to orbit round Didymos, which decreased to 11 hours and 23 minutes after the affect. A follow-up mission will launch in October to check the aftermath of the DART mission. In contrast to NASA’s mission, it’s not clear what sort of deviation the Chinese language mission will trigger to its goal asteroid, and whether or not it might have an effect on its distance from Earth.
China desires to get in on the planetary protection motion, launching what is basically these two missions mixed. With the 2 spacecraft launching on the similar time, the Chinese language asteroid deflection take a look at may probably present extra perception into the way to defend our planet from incoming threats, in addition to be taught extra in regards to the origins of the photo voltaic system by probing the traditional house rocks orbiting across the Solar.
