Chandrayaan-3 reaches final lunar orbit for landing
Click for interactive map.
India’s Chandrayaan-3 spacecraft completed its final lunar orbital engine burn today, placing it in the correct orbit to release the lander Vikram, carrying the Pragyan rover.
The release is scheduled for tomorrow, with the landing targeting August 23, 2023. This will be India’s second attempt to softland an unmanned probe on the Moon. The Vikram lander of Chandrayaan-2 failed in 2019 during its final engine burn above the surface, crashing thereafter. Engineers at India’s space agency ISRO spent several years upgrading that lander to better insure this new attempt would succeed.
The lander has been given more ability to manoeuvre during the descent, the mission allows for a bigger 4 km x 2.4 km area for landing, more sensors have been added, one of the thrusters has been removed, and the legs of the lander have been made sturdier to allow for landing even at slightly higher velocity. More solar panels have also been added to ensure that the mission can go on even if the lander does not face the sun. More tests to see the capability of the lander in different situations were carried out to make Chandrayaan-3 more resilient.
Both Vikram and Russia’s Luna-25 lander, scheduled for touchdown on August 21, will land in the high southern latitudes of the Moon, at about 70 degrees. They are not going to the Moon’s south pole, as many news reports claim.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
