Some exciting Science to be done when Apophis visits, way out of reach of the Starlinks

I hope there are dashboards for the missions, I liked those with Artemis!

[Перевод] Встреча с Апофисом

Астероид Апофис, «Бог Хаоса», пролетит мимо Земли в апреле 2029 года — и три космических зонда будут наблюдать за ним. 19.09.2025, Эндрю Джонс, space.com Если все пойдет по плану, Ramses, DESTINY+ и OSIRIS-APEX будут наблюдать за встречей с близкого расстояния.

The last session at the #Apophis T-4 workshop today is reviews of the #OSIRISAPEx and #RAMSES spacecraft and what they are planned to do at the asteroid:

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

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。

@bjn2 Apophis will miss the Earth.

The RAMSES mission design was not approved until it could demonstrate no possibility of creating a hazard.

Likewise for #OSIRISAPEx : https://www.lpi.usra.edu/sbag/documents/Apophis_SAT.pdf .

We have strict instructions to not make piles of rock fall from the sky.

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.

NASA's Science Mission Directorate has issued a Request for Information for plans to use the Janus spacecraft currently in storage to fly by the asteroid #Apophis in 2029: https://nspires.nasaprs.com/external/viewrepositorydocument/cmdocumentid=1022051/solicitationId=%7BF77502A1-B310-35A0-1ACB-B24E17578FE3%7D/viewSolicitationDocument=1/JANUS%20RFI%20Text%20NNH24ZDA009L.pdf
