Falcon 9 Falcon 9 Rocket It is a partially reusable two-stage-to orbit medium-lift launch vehicle designed and manufactured by SpaceX in the United States.It is an orbital launch vehicle. It is powered by Merlin engines,also developed by SpaceX,burning cryogenic liquid oxygen and rocket-grade kerosene as propellants. This rocket evolved with versions:- 1. v1.0( 2010-2013) 2. v1.1 (2013-2016) 3. v1.2"Full Thrust" (2015 -present) Variant v1.2 is divided in three blocks: 1. Block-3 (retired) 2. Block-4 (retired) 3. Block-5 (active) Cost per launch: New:$62M(2020)                              Reused:$50M(2019)                                     Falcon 9 can lift payloads of up to 22800kg to low Earth orbit(LEO) and 8300kg to geostationary transfer orbit(GTO)when expended, and 5500kg to GTO when first stage is recovered.

Chandrayaan-1 It was the lunar probe of ISRO mission under Chandrayaan program.It was launched on October 22, 2008 and operated until August 2009.It was the first lunar mission of ISRO It includes a lunar orbiter and impactor.It was inserted in lunar orbit on November 8,2008. ISRO launched this satellite using a PSLV-XL rocket from Satish Dhawan Space Centre,at Sriharikota,Andhra Pradesh. The estimated cost for the project was US$54 million. Specifications of Chandrayaan-1 Mass- 1380 kg at launch           675 kg at lunar orbit           523 kg after releasing the impactor Dimensions- Cuboid in shape of  approximately 1.5m(4.9 ft) Communication- X band,0.7m(2.3 ft)diameter dual gimballed parabolic antenna for payload data transmission.The Telemetry,Tracking and Command (TTC) communication operates in S band frequency. Power- The satellite was mainly powered by solar array,which include one solar panel covering a total area of 2.15×1...
