1. CHANDRAYAAN 3 A Mission Of Hope For The Future Of Space Exploration.

2. Chandrayaan 3 is India's third lunar mission to soft land on the lunar south pole region. The mission will conduct scientific experiments to study the lunar geology, atmosphere, and environment. Introduction Of Chandrayaan 3

3. Three Mission Objectives Demonstrate safe and soft landing on the lunar surface Conduct ROVER operations on the Moon Conduct on-site experiments on the lunar surface 1 2 3 Remotely Operated Video Enhanced Receiver (ROVER) is a system which allows ground forces, such as Forward air controllers (FAC), to see what an aircraft or unmanned aerial vehicle (UAV) is seeing in real time by receiving images acquired by the aircraft's sensors on a laptop on the ground.

4. Key Technologies Hazard Detection and Avoidance Lander Hazard Detection & Avoidance Camera and Processing Algorithm Landing Leg Mechanism. Inertial Measurement Laser Gyro based Inertial referencing and Accelerometer package Altimeters Laser & RF based Altimeters Propulsion System 800N Throttleable Liquid Engines, 58N attitude thrusters & Throttleable Engine Control Electronics Velocimeters Laser Doppler Velocimeter & Lander Horizontal Velocity Camera Navigation, Guidance & Control Powered Descent Trajectory design and associate software elements 1 2 3 4 5 6 An altimeter or an altitude meter is an instrument used to measure the altitude of an object above a fixed level. Laser Doppler velocimetry, also known as laser Doppler anemometry, is the technique of using the Doppler shift in a laser beam to measure the vibratory motion of opaque, reflecting surfaces. The measurement with laser Doppler anemometry is absolute and linear with velocity and requires no pre-calibration. An inertial measurement unit (IMU) is an electronic device that measures and reports a body's specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers.

14. The Earth-Moon average distance is roughly 384,400 kilometers. To save fuel, Chandrayaan-3 has chosen a longer route to the Moon. This adjusted path aims to ensure a gentle landing of the mission's Vikram lander on the Moon's South Pole area. The expected timeline for this soft touchdown is approximately 42 days after launch, specifically around August 23 or 24. Trajectory

20. How you/we can be a part of ISRO

21. There are people designing all sorts of electronic packages required in a launch vehicle which includes control electronics packages, various sensors and it’s interface units, packages used for base band communication, packages for radio frequency communication, antennas for different communication requirements, processors used in launch vehicles, packages required for testing, batteries and power modules for powering all these packages during flight etc … the list goes on and on. The design philosophy is different from the commercial package manufacturing and it has to qualify winder range of environmental specifications like temperature, vibration, shock etc. Here main focus is on reliability and safety due to high cost of launch vehicle and satellites. As an EC engineer your job can be designing or testing any of these kinds of packages. It can be making PCBs or writing FPGA codes. It can be related to designing large motors or designing a small inertial sensor or image processing and data compression algorithm development. Or may be selection of suitable MIL grade components from the market, procuring it, flight qualifying it. End to end everything you may need to handle including the paper work. There are even boring and mostly paper work jobs related to outsourced production of packages etc. You may be involved in various phases of testing. Or analysing test data and identifying failures in packages or components. Sometimes, it can be automation of certain tests. If you have read ‘The Martian’ novel, you will understand the importance of testing. Some of Launch vehicle testing teams have to travel to other centres occasionally (mainly LPSC, IPRC and SDSC). Vikram Sarabhai Space Centre(VSSC)

22. There will be cases where your job may be to support some mechanical engineer's work. May be you will have to work on miniaturized package development of an already existing package. If you are in launch vehicle project, your work will be coordinating work between various agencies, preparing schedules and getting work done before deadlines. There can be even some junk work like arranging food or vehicles if necessary. Sometimes your work can be even analysing data from a payload in Mangalyaan or developing payload for Chandrayaan -II (usually most payloads for satellites will be developed by SAC, LEOS, ISAC etc but for scientific mission at least one payload will be developed by Space Physics Laboratory in VSSC) Your work can be freezing Electrical configuration of next generation launch vehicles or accommodating changes in coming flights of PSLV or may be technology transfer to some industries. Here, I want add one more thing that each PSLV is electrically more or less the same (except at times when major architectural changes are undertaken), at the same time there will be always some changes for each flight. At present there is a renewed emphasis on developing a modern and advanced architecture for launch vehicles to reduce mass and turn around time. So coming five to ten years will decisive in this development. The last time major changes in avionics architecture happened more than 10 years ago (with work on it started around 2000). Usually incremental changes are only done due to reliability issues and schedule. Here, in ISRO many times the work can be multi-disciplinary and you may need to work as a team with people with different backgrounds. Also your job may not be properly defined (especially if it is a new work), you may have to do whatever is required to get the final product. You may also have to parallelly undertake development work as well as operational work in some divisions.

23. If u want to be a part of ISRO T hrough all the semester in Engineering minimum marks should be 65% . Must have a 4 years full time B.tech  degree in your specified Engineering stream A ge should be between 18 - 42 years. ISRO conducts its own paper and it is almost like GATE. Some tips on what to do to qualify the test :- 1. You need to be good at fundamentals. test will be fairly easy. 2.there are 80 questions you need to plan. 3.Try to solve the problems of old ISRO Questions papers. 4.prepare well and strive hard . 5.make sure your basics are good in 2 to 3 subjects of your domain.
