GISAT-1 Launch; ISRO to launch India's most advanced Eyes in Space
 |
| GISAT-1 satellite |
ISRO is planning to launch a geostationary imaging satellite called GISAT-1 on August 12, 2021.
This mission was supposed to launch on March 5, 2020. But it got delayed due to the covid pandemic and technical errors.
This mission will help India to get an extra advanced set of eyes in preventing natural hazards and disasters.
Why GEO Stationery?
ISRO has already had these kinds of imaging satellites placed in low Earth orbit.
But these lower earth-orbiting satellites provide only step-by-step imaging of India. They have a frequency of imaging India only once in a few days.
In order to comprehend this, ISRO is placing this GISAT-1 satellite in a geostationary orbit, which is 36000 km away from Earth.
A satellite placed in that orbit will constantly image the Indian subcontinent.
By staying in the geostationary orbit, this satellite will help us in the field of Metrology and disaster relief.
These fields require frequent imaging, which GISAT-1 will play a vital role.
GISAT-1 mission objective
The lifetime of this satellite is about seven years. It has a mass of about 2275 kg and it is powered by a solar array and batteries.
This GISAT-1 satellite will help us in the following fields
- Monitoring of weather
- Agriculture development
- Rural and urban planning
- Mapping of natural resources
This satellite gives early warnings of natural hazards and disasters. It takes close-up pictures of border areas with Pakistan and China.

| GSLV Mk-II Launch Vehicle |
GSLV-F10 Launch vehicle
The launch vehicle used to launch this rocket is called the GSLV Mk-II. This vehicle has three stages.
The first stage has 4 strap-on boosters which have 42 tons of liquid propellant.
The third stage of this rocket is powered by a cryogenic propellant.
This rocket will launch from the second launch pad of Satish Dhawan Space Centre, Sriharikota.
ISRO is also aiming to launch its astronauts into space next year in a mission called Gaganyaan
