Da, pacat. Poate vor publica o inregistrare video cu ultimul minut.

Cand te bazezi asa mult pe un sistem autonom, cea mai mica eroare sau ceva neprevazut si e gata.. :(

Nu a fost totul in van.

If Vikram failed to land - which it looks like - REMEMBER the ORBITER is where 95% of the experiments are. The Orbiter is safely in Lunar orbit and performing its mission. This is not a total failure. Not at all

De programul Lunohod nu ai auzit?
Voi astia numai dupa ora Moscovei mai cantati. Pe toate subiectele.
Ma gandeam la Marte, acolo au dat-o in bara pretinii vostri.

De Lunohod am auzit, la vremea lui. Am facut chiar un model, pentru scoala, la orele de practica. Era comandat prin fir, la magazine nu erau inca jucarii electrice...
Mare lucru atunci pentru rusi, bravo lor, dar vezi d-ta ca n-am auzit de vreo teorie a conspiratiei despre rusi cu Luna 9 sau Lunohozii... Sau ca de ce nu s-au intors pe luna vreme de 50 ani... Doar de mericani se leaga, de unde si categoria de frustrati care umbla cu teoriile.
Tot respectul pentru oamenii de stiinta sovietici/ rusi, sunt foarte foarte buni, pacat ca nu au suportul necesar din partea restului industriei si conducerii.
In schimb Indienii sunt pe cai mari, au rachete spatiale impresionante, program clar, dezvoltat si multa ambitie si entuziasm, nu e fortare cu ordin de la partid, ca la comunisti.
E off topic dar cu inteles: acum vreo 20 ani, cand o racheta mare chinezeasca, un Mars Lung din ala a luat-o la orizontala cazand intr-o localitate (rasa...) guvernul chinez s-a razbunat pe toti aia implicati, pana la ultima fatuca plimbatoare de hartii, i-a ucis, incarcerat, deportat, la gramada. Ani de zile le-au trebuit sa refaca echipele, vreo 10 ani intarziati.

Data viitoare indienii vor reusi. Asa au patit si sovieticii si americanii la primele incercari, pana au prins smecheria.

Comunicat oficial al ISRO

Quote

September 7, 2019
Chandrayaan-2 mission was a highly complex mission, which represented a significant technological leap compared to the previous missions of ISRO, which brought together an Orbiter, Lander and Rover to explore the unexplored south pole of the Moon. Since the launch of Chandrayaan-2 on July 22, 2019, not only India but the whole world watched its progress from one phase to the next with great expectations and excitement. This was a unique mission which aimed at studying not just one area of the Moon but all the areas combining the exosphere, the surface as well as the sub-surface of the moon in a single mission. The Orbiter has already been placed in its intended orbit around the Moon and shall enrich our understanding of the moon’s evolution and mapping of the minerals and water molecules in the Polar Regions, using its eight state-of-the-art scientific instruments. The Orbiter camera is the highest resolution camera (0.3m) in any lunar mission so far and shall provide high resolution images which will be immensely useful to the global scientific community. The precise launch and mission management has ensured a long life of almost 7 years instead of the planned one year. The Vikram Lander followed the planned descent trajectory from its orbit of 35 km to just below 2 km above the surface. All the systems and sensors of the Lander functioned excellently until this point and proved many new technologies such as variable thrust propulsion technology used in the Lander. The success criteria was defined for each and every phase of the mission and till date 90 to 95% of the mission objectives have been accomplished and will continue contribute to Lunar science , notwithstanding the loss of communication with the Lander.

Sistemul este autonom, insa este programat de ingineri. Daca este proiectat corect si scenariul stabilit cum trebuie (testat, prevazute posibilele puncte crtitice etc), nu ar trebui sa existe surprize, mai ales ca nu discutam de o noutate tehnica absoluta ci de ceva care s-a mai facut pana acum.
