The Chandrayaan 2 mission has plan a long plan since the Indian Condominium Research Organisation first sought and won acclaim for the mission in 2008. Eleven years later, we’re unruffled studying from our errors at the same time as we strive to settle the distance of the Vikram lander, after it nearly pulled off a now now not-so-tender-landing shut to its meant landing space in the South Polar space. Even that atomize is one thing of an success, though.

Beginning with the most up-to-date updates from ISRO regarding the Chandrayaan 2 mission and its incommunicado Vikram lander, right here’s a checklist of the entire main events culminating in the Chandrayaan 2 mission as we realize it nowadays, dating abet to its precursor — the Chandrayaan 1 mission — in 2003.
