Key points of Chandrayaan 3:

Chandrayaan-3is the third lunar exploration mission ready for take off in the fourth operational mission (M4) of LVM3 launcher.
The soft landing on the moon’s surface is planned for late August.

The largest and heaviest LVM3 rocket (formerly GSLV MkIII), fondly called as ‘fat boy’ by ISRO scientists for its heavylift capability, has completed six consecutive successful missions.

Chandrayaan-3 is a follow-on mission to Chandrayaan-2. Unlike its predecessor, which carried an orbiter along with Vikram & Pragyan (the rover), Chandrayaan-3 is a composite of 3 modules: Propulsion, lander and rover.

The spacecraft will weigh 3,900kg – the propulsion module weighs 2,148kg, while the lander module, including the rover, weighs 1,752 kg.
Unlike Chandrayaan-2, when the landing was tracked through a Madrid (NASA-JPL) station, this time tracking of the lander will happen fromIsro Telemetry, Tracking and Command Network (Istrac) station in Bengaluru.

The DEFENCE ministry on Thursday approved the acquisition of 26 Rafale-Marine fighter jets and three Scorpene diesel-electric submarines from France, paving the way for the formal announcement of the two proposed mega deals at the Modi-Macron summit.

The Rajnath Singh-led Defence Acquisitions Council (DAC) accorded the acceptance of necessity (AoN) to the twin procurements for theNavy, which together will cost upwards of Rs 80,000 crore (9 billion)

With the indigenous twin-engine deck-based fighter (TEDBF) likely to take at least a decade to become operational, the Navy had pushed for the 26 Rafale-M jets as an interim measure.

Less than a month after the historic visit of Prime Minister Narendra Modi to the US, a Congressional Senatorial Committee has passed a resolution recognisingArunachal Pradeshas an integral part of India.
