Vilniaus Anarchistų SąjungaMar 10

Kviečiame prisijungti prie mūsų ir toliau kartu skaityti bei aptarti Anarchistinės politinės mokyklos modulius kovo 14 d. Šią savaitę aptarsime 3 modulį socialiniame centre „Luna16“ (Šeiminyskių g. 16).

Melburno anarchistų komunistų grupės parašytas įvadas į anarchizmo revoliucines idėjas ir strategijas, Anarchistų politinė mokykla yra 10 modulių rinkinys, kuriame aptariama, kaip iš tiesų veikia kapitalizmas ir vyriausybės, kaip galime kovoti su valdančiąja klase ir kodėl mums reikia revoliucijos.

Sesijos metu perskaitysime tekstą, po to aptarsime jį ir jame pateiktas idėjas. Dalyvauti sesijoje nereikia jokio išankstinio pasiruošimo. Jei norite, galite iš anksto perskaityti modulį čia:

But why land in the dark? I note that they spent 3 days in lunar orbit before landing, so they arrived in orbit before sunset. Maybe there was just not enough time to check everything before sunset and be ready to land. Tracking during those 3 days helped improve knowledge of mascons, the gravity anomalies which complicate low orbit operations. But we don't really know why this happened the way it did. I close with another site map and a closeup LRO image composite. #moon #Luna16

Not much was said about this at the time, but more recently we have learned that the pictures did in fact reveal some details. Apparently, bright glints off rocks could be seen faintly, but the image quality was too poor for them to be useful. That's too bad. I think that if we could get the original data off the big data tapes (which would almost certainly be in the Lenin Library), modern image processing could probably salvage something from them. #moon #Luna16

Each camera took a half-panorama from the horizon to the sampling area, so the sampling area was seen twice for stereo mapping. If a rock was in the way I think the arm could move a little to the left or right to avoid the obstacle. Why did we not see the pictures? NSSDCA points out they landed 60 hours after sunset, so not much to see! But they were taken and transmitted anyway, probably just to test the system. But what about Earthshine? #moon #Luna16

Here is a picture of Luna 16 from Wikimedia:

My image is part of that picture, annotated. Note the two cameras.

NSSDCA describes the mission:

They say: "... strong and good quality television pictures were returned by the spacecraft. However, such pictures were not made available to the U.S. by any sources ..."

The pictures were also never published in the various publications on the mission. What's going on? #moon #Luna16

That very restricted area was a band roughly connecting the Luna 15 and 16 sites on that map. We'll be seeing several missions go to this area. Given such a restriction, the Soviet goal was to sample Mare Crisium, Mare Fecunditatis and the strip of rugged highlands between them. Two different lava flow areas and the highlands, a good suite of samples. We'll look a bit more closely at Luna 16 tomorrow.

... but if they do it going backwards relative to the Moon's orbital motion, as they depart they are now orbiting Earth slower than the Moon, so they fall in towards Earth. By controlling the velocity and direction they can simply fall to Earth, timing it so they land in Soviet territory.

The price they paid for this convenience was a very restricted area from which to launch. All Soviet sampling missions went to a small area. This map shows the region. #moon #Luna16

Luna 15 was supposed to collect lunar regolith and return it to Earth, but it crashed. The next attempt succeeded. This was Luna 16, coming in the gap between Apollos 13 and 14. The Luna sample return missions had an ingenious method of returning to Earth. To escape the Moon they had to leave it at greater than lunar escape velocity. If they do that going forwards along the Moon's orbit they are going faster than the Moon and will fly out away from Earth... #moon #luna16
