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:

L'asteroide Aphosis in viaggio verso la terra. Apophis ci sfiorerà nel 2029, al punto che ne avvertiremo la forza gravitazionale. Nel 2029 l’asteroide Apophis sfiorerà la Terra, avvicinandosi più dei satelliti artificiali e perfino facendo sentire la sua gravità.
L’asteroide Apophis, che prende il nome dal dio egizio Apopi, signore del caos e della distruzione, è un asteroide vicino alla Terra...

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
They would accompany the #Ramses and #OSIRISAPEx missions to the asteroid and everyone who will be observing it from Earth.

@SkipHuffman On 2029 April 13, #Apophis will pass 38012 ± 3 km away from Earth's center with relative velocity 7.42 km/s and v infinity 5.84 km/s.
Nobody and nothing touches it until after the flyby; to avoid perturbing its trajectory: https://www.lpi.usra.edu/sbag/documents/Apophis_SAT.pdf
The #OSIRISAPEx mission will arrive at the asteroid a week later: https://www.planetary.org/space-missions/osiris-apex
There is the option have the Janus spacecraft fly past the asteroid before it passes Earth; but that requires funding that has not been approved.

Discussion of the #RAMSESmission proposal from ESA to rendezvous with #Apophis before the 2029 flyby; for which a decision needs to be made soon.
Operations plan notes that orbiting the asteroid would be impossible during the flyby.
(Again, the #OSIRISAPEx mission from NASA will catch up with Apophis only after the flyby; but even then it will mostly formation-fly and make hyperbolic passes rather than orbiting.)
Five years from today, asteroid #Apophis will make a very close flyby.
There will be many Earth-based observations, including by #TeamRadar, and the #OSIRISAPEx mission will get a spacecraft out there after the flyby.

The #OSIRISAPEX spacecraft seems to have made it through its first perihelion passage in good shape. #BetterKnowAnAsteroid

The NASA Small Bodies Assessment Group is meeting this week: https://www.hou.usra.edu/meetings/sbagjan2024/technical_program/.
Begins by appropriately hyping the #OSIRISREx sample return and the #OSIRISAPEX extended mission.
Also on the agenda:
Options for new planetary radar facilities ( #TeamRadar approves ).

NASAのOSIRIS-REx宇宙船が、小惑星アポフィスを研究するための旅に出発しました。アポフィスは地球に最も接近する予定で、2029年4月13日には地球から2万マイル以内を通過すると考えられています。OSIRIS-APEXは地球接近後にアポフィスを調査し、
18ヶ月間その近くで作動します。さらに、OSIRIS-APEXはアポフィスの表面を詳細にマッピングし、地球接近による変化を調査します。 #NASA #宇宙 #OSIRISAPEX
The graphic below from NASA shows the orientation of OSIRIS-APEX as viewed from the direction of the Sun during the weeks around perihelion.
The back side of the solar array on the right is turned towards the Sun. This array shades and protects critical areas of the spacecraft.
The solar array on the left is facing the Sun (although not directly) and is being used to generate power.

Meanwhile, OSIRIS-APEX (as it is now known) is on its way for a close flyby of the Sun on Jan 2, 2024.
Current distance from Sun: 91.62 mil km
Perihelion: 74.18 mil km
Flyby of asteroid Apophis: Apr 2029
The spacecraft was not designed to get this close to the Sun; the spacecraft will stay in a fixed orientation with respect to the Sun and use one of its solar arrays as a shield. Most instruments will be turned off until Mar/Apr.

Solar System exploration as of October 2023.
Hello to the #SLIM moon mission and the #Aditya solar mission.
#OSIRISREx delivered its asteroid sample and has been re-tasked as #OSIRISAPEx to study the asteroid #Apophis.
