2029年の地球フライバイ中には、『混沌の神』と呼ばれる小惑星が地震や土砂崩れによって変化する可能性があることが研究で明らかになった
https://www.space.com/the-universe/asteroids/god-of-chaos-asteroid-may-be-transformed-by-tremors-and-landslides-during-2029-flyby-of-earth-study-finds
2029年に地球に接近する小惑星アポフィスが地震や地滑りで変化する可能性がある。アポフィスは4月13日に地球に2万マイルの距離で最接近する見通し。NASAのOSIRIS-APEXが研究を予定。
#Asteroid #Apophis #NASA #OSIRISAPEX -
NASA's Science Mission Directorate has posted an updated Request for Information from any group interested in using the #Janus spacecraft currently in storage to fly by the asteroid #Apophis around its 2029 flyby of Earth: https://nspires.nasaprs.com/external/solicitations/summary.do?solId={F77502A1-B310-35A0-1ACB-B24E17578FE3}
Responses are due by October 28.
This would accompany the #RAMSES and #OSIRISAPEx spacecraft visiting Apophis before and after the flyby and everyone on Earth who will be observing the flyby as it happens.
