<p>Bengaluru: The Chandrayaan-4 Mission is at least two years away, but the ISRO has identified a location in the South Polar region of Moon to land its lander.</p>.<p>The Union government has approved the Chandrayaan-4 mission, designed as a lunar sample-return mission and it will be India’s most complex lunar endeavour yet.</p>.<p>"We are targeting 2028 for Chandrayaan-4," ISRO chairman V Narayanan had earlier said.</p>.After 2 failures, ISRO to attempt PSLV launch in June: Jitendra Singh.<p>According to ISRO officials, they had zeroed in on four sites of the Mons Mouton (MM) and found one of them suitable for landing on the lunar surface.</p>.<p>Mons Mouton is a region on the Moon.</p>.<p>Officials said they had identified locations -- MM-1, MM-3, MM-4 and MM-5. Of them, MM-4 was chosen for the landing.</p>.<p>"The four sites in Mons Mouton area were fully characterised with respect to terrain characteristics using high resolution Orbiter High Resolution Camera (OHRC) multi view image datasets," they said.</p>.<p>It was found that one kilometre by one kilometre area around MM-4 contains "the less hazard percentage, mean slope of 5 degrees, mean height of 5334 metres and most number of hazard free grids of size 24 metres into 24 metres. Hence, MM-4 could be considered as the potential site of Chandrayaan-4 mission," officials said.</p>.<p>Chandrayaan-4 consists of a propulsion module (PM), a Descender module (DM), an Ascender Module (AM), a Transfer module (TM) and a Re-entry Module (RM).</p>.<p>The DM and AM combined stack will soft land on moon surface at the designated site.</p>.<p>The main soft landing will be done by an appropriate stack (AM+DM) descent trajectory with navigation, guidance and control system while the safe landing can be ensured by a proper selection of the landing site that meets all the constraints of the Lander.</p>
