The Indian Space flight mission Gaganyaan will orbit the Earth for seven days and is scheduled in December 2021. Four Indian Air Force Pilots are to participate in the mission. The training for the pilots to enter space has commenced in Russia.
The mission is undertaken in the low earth orbit at 300 – 400 km from the earth. It would comprise an effective crew escape system and ejection provisions for the pilots in case of rocket explosion.
Russia’s contribution in the mission
Russia will offer semi cryogenic rocket engine technology to India under India’s Make – in – India Program. Later the rocket engines will be made in India
Apart from this India is planning to set a NaviC station in Russia and Russia will also be allowed to set up a NaviC station base in Bengalaru, India. The negotiations are on and the deal is yet to be signed.
The announcement about the training was made at the inaugural function of “Citizen Familiarization Program” by the VSSC – Vikram Sarabhai Space Center Director S Somnath
Citizen Familiarization Program
The Program was conducted during the celebrations of World Space Week 2019. The main purpose of the program is to inform the citizens of the country for what purpose their tax money is being utilized in ISRO. ISRO had invited senior citizens of the country and was attended by more than 400 senior citizens. ISRO also sought their advises and suggestions
The ISRO research and programmed have contributed greatly towards economic development of the country. It has helped to improve digital communication, defence communication, mapping, accurate weather forecast, agricultural production, etc

The robotic Mission Extension Vehicle-1 (MEV-1) was successfully launched atop of Russian Proton rocket from Baikonur Cosmodrome in Kazakhstan. It is first of its kind commercial satellite-servicing spacecraft. It is designed to dock with aging spacecraft more than 22,000 miles above Earth, then extend its life with aid of solar-electric thrusters. Its successful launch marks beginning of era of commercial satellite servicing in the space.
About Mission Extension Vehicle-1 (MEV-1)
It was built by Virginia-based company Northrop Grumman. It will attempt first-ever docking between two spacecraft near geostationary orbit (nearly 36,000 kilometers over the equator that is popular with communications satellite operators). It will link up with 18-year-old Intelsat communications satellite early next year. Once docked, with this old satellite, it will take over propulsion for Intelsat 901 satellite, which is running low on fuel. It will then put Intelsat back into an ideal target orbit — thus extending its useful life by as many as five years.
MEV-1’s Life span: It is designed for 15-year useful life, and can dock and undock multiple times, thus, it will be providing well in excess of 15 years of mission extension to orbital geosynchronous satellites l running low on its own propellant supply.
