Естественный интеллект против искусственного: противостояние на Луне

Пока я сажал зрение ночами рассматривая черные фотографии Луны в поисках «Луны-9» , группа британских и японских ученых решила поручить ту же работу искусственному интеллекту. В результате, к 60-й годовщине первой мягкой посадки на Луну, вышло сразу два исследования с попытками обнаружить советский космический аппарат «Луна-9» на поверхности естественного спутника Земли. Обе команды показали предполагаемое место посадки, но это разные места.

A giant leap in orbital imagery is what we need to realize advanced Moon missions

Thinking about the time Buzz Aldrin lamped that Lunar Hoax Conspiracist and that's exactly what I would have done too.

But of course, you can't convince such people with facts, how dare you....

Indiase Chandrayaan-2 vermijdt botsing met Koreaanse Danuri rond de Maan

De Indiase Chandrayaan-2 maanorbiter manoeuvreerde in september om een nauwe nadering van de Zuid-Koreaanse Danuri maansonde te voorkomen. Dit staat in een onlangs gepubliceerd rapport van de Indian Space Research Organisation (ISRO).

De Indi

On 19 September 2024 Orbital Maneuver OM-87 plan for raising perilune of Chandrayaan 2 Orbiter (CH2O) was modified to avoid the potential close conjunction risks with Korea Pathfinder Lunar Orbiter (KPLO) around 1st October, 2024. The tentative plan for the next manoeuvre OM-88 scheduled on 1st October, 2024 was also adjusted to avoid post manoeuvre conjunctions with other lunar orbiters (KPLO, LRO).

In August 2024, planned Orbital Maneuver OM-86 for apolune reduction and circularization of Chandrayaan-2 Orbiter (CH2O) was modified to avoid the potential close conjunction risks with Korea Pathfinder Lunar Orbiter (KPLO) around 15-16 August 2024.

In July 2024 two close approaches between Chandrayaan-2 Orbiter and other lunar orbiters resolved through inter-agency coordination.

• Close approaches with and NASA's Lunar reconnaissance Orbiter (LRO) on 12 July
• Potential close conjunction risk with Korea Pathfinder Lunar Orbiter (KPLO) on 25 July

Yet another conjunction event avoided between Chandrayaan-2 Orbiter and South Korean lunar orbiter KPLO.

"The risks associated with close conjunctions of CH2O and KPLO on May 24, 2024 were mitigated by coordination with KARI team. Two orbit maintenance maneuvers (OM-83 and OM-84) were executed for CH2O."

Lunar orbit is getting crowdy and orbiters have had to frequently perform conjunction avoidance manoeuvres.

Both Aditya-L1 and Chandrayaan-2 have made observations on recent solar eruptive events and their signatures have been analysed.

https://www.isro.gov.in/ISROCapturestheSignaturesoftheRecentSolarEruptiveEvents.html

On spacecraft impact:

No significant degradation in the NaVIC service, no major upsets observed in any of the 30 GEO spacecrafts. No single event upsets were seen.

Momentum Wheel speed deviations seen on some sats.

Spacecrafts with one-sided panel required frequent momentum dumping.

@AkaSci Some nice image processing done here as well.

125 meter is impressive as they had to redirect and max. range after redirect is 150 meters.

For Chandrayaan 2 the target spot was 60×60 meters!

ISRO achieved a significant milestone as it successfully established a two-way communication link between the Chandrayaan-2 orbiter and the Chandrayaan-3

@pradx Another good read mentioning reasons like lander mass increase behind the fallout. Eventually ISRO too had to switch launch vehicle to LVM3 as it couldn't keep the CY2 mass under the capacity of GSLV.

NASA satellite finds crashed Indian Moon lander. #Chandrayaan2
https://buff.ly/2LfXpR6  Pictures showed the site of the spacecraft''s impact and debris, with parts scattered over almost two dozen locations spanning several kilometers.

The #Chandrayaan2 Vikram lander has been found by our @NASAMoon mission, the Lunar Reconnaissance Orbiter. See the first mosaic of the impact site https://www.nasa.gov/image-feature/goddard/2019/vikram-lander-found?utm_source=TWITTER&utm_medium=NASA&utm_campaign=NASASocial&linkId=78096390 

#Chandrayaan2's Vikram lander hard-landed as reduction in velocity during its descent did not match with the designed parameters, according to the government.
