Context

• The Indian Space Research Organisation (ISRO) is preparing for its next big commercial mission to launch a Singaporean Earth Observation satellite - TeLEOS-2.

TeLEOS 2: Fast Facts

• The TeLEOS 2 is a 750kg Earth Observation Satellite.
• It is designed to capture round-the-clock, all-weather satellite imagery of the Earth.
• It features synthetic aperture radar which can provide data in 1-metre resolution.
• It will provide imagery that will be used for hotspot monitoring and haze management, along with assistance in aviation accidents, search and rescue operations, and more.
• TeLEOS-2 will be launched aboard ISRO’s Polar Satellite Launch Vehicle (PSLV), which will take off on its 55th mission.
• The ISRO will use the XL variant of PSLV in the upcoming C-55 mission. 

Note: This is also not the first time the ISRO will be launching a Singaporean satellite from India. It launched three Singaporean satellites with the PSLVC-53 mission in June 2022 and in 2015, the ISRO launched the TeLEOS-1, which was the first Singapore commercial Earth Observation Satellite.

About PSLV

• The Polar Satellite Launch Vehicle (PSLV) is the first Indian launch vehicle with liquid stages.
• The PSLV is called the 'the Workhorse of ISRO' as it has consistently delivered various satellites to Low Earth Orbits.
• The rocket can carry up to 1,750 kg of payload to 600 km altitude.
• It can also place multiple payloads into orbit with multi-payload adaptors.
