[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
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。

@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.
For details of current plans: https://www.hou.usra.edu/meetings/apophis2024/

Preliminary telemetry indicates that NASA’s #OSIRISAPEX spacecraft successfully completed a two-month operation that brought it 25 million miles closer to the Sun than it was designed to function: https://blogs.nasa.gov/osiris-apex/2024/02/20/nasas-osiris-apex-completes-1st-perihelion/ - the spacecraft continues its journey to reach asteroid Apophis in April 2029.

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’s #OSIRISAPEX spacecraft continues to transmit a telemetry signal and operate normally in its new configuration, having just flown closer to the Sun than ever before: https://blogs.nasa.gov/osiris-apex/2023/12/01/nasas-osiris-apex-to-fly-closer-to-sun-to-reach-asteroid-apophis - once OSIRIS-APEX is farther from the Sun in March, the mission team will re-orient the spacecraft to point its high-gain antenna toward Earth to allow for high-speed communication.

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.Credit: NASA/Goddard/University of Arizona

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 2029The 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. -
NASA’s OSIRIS-REx Mission brings sample from asteroid Bennu to Earth
NASA’s first asteroid sample return mission, OSIRIS-REx, launched seven years ago in 2016 to near-Earth asteroid Bennu has delivered the asteroid...........

#OSIRISREx mission briefing needs to say that both sample curation and #OSIRISAPEx are classified as essential and can keep going if there is a government shutdown.
Require that there be #NoGovernmentShutdown, USA. And require that Congress change the rules that allow shutdowns.
