Context

• Earth observation Geo-imaging satellite“EOS-03”is scheduled for launch in third quarter of 2021.
• This is the first developmental flight of Small Satellite Launch Vehicle or SSLV will be launched from Satish Dhawan Space Centre, Sriharikota.

About

• It would enable near-real time monitoring of natural disasters like floods & cyclones.
• EOS-03 is capable of imaging the whole country 4-5 times daily.
• In addition to natural disasters, EOS-03 would also enable monitoring of water bodies, crops, vegetation condition, forest cover changes etc.
• The first earth observation satellite was launched in 2020 along with nine customer satellites.
• The EOS-1 was intended for applications in agriculture, forestry and disaster management support.

First SSLV Developmental Flight

• SSLV is ideal for on-demand, quick turn-around launch of small satellites.
• SSLV is a three-stage, all-solid launch vehicle that can carry a payload weighing 500 kilograms to the polar orbit, 500 kilometers above Earth's surface and a 300-kilogram payload into Sun Synchronous Polar Orbit.

What is a propellant?

• Rockets work because every action has an equal and opposite reaction (according to Sir Issac Newton's third principle).
• In order for the rocket to rush forward, something has to rush backwards. That thing is the propellant.
• The propellant is a material that spews out of the back of the spacecraft giving it thrust, or a push forward.
