1. Earth Observation Satellite-6 (EOS-6) launched by the ISRO
2. ‘IKSHAK’ Third ship of survey vessel (large) launched


Syllabus: GS 3, Science and Technology.

Prelims: Earth Observation Satellite-6.

Mains: Awareness in the field of space.

Context: ISRO launches Earth Observation satellite-6.

Details:

• The Indian Space Research Organization (ISRO) in partnership with the Ministry of Earth Sciences (MoES) launched the Earth Observation Satellite-6 (EOS-6) from Satish Dhawan Space Centre (SDSC), Sriharikota.
• EOS 6 is the third-generation Indian satellite for monitoring the oceans.
• The mission is consequent to OceanSat-1 (IRS-P4) of 1999 and OceanSat-2 of 2009.
• The satellite was launched in Polar Satellite Launch Vehicle (PSLV) – PSLV-C54. It also accommodated other small satellites along with Oceansat-3.
• It was placed in the polar orbit at a height of about 740 kilometers above sea level.
• Its weight is approximately 1100 kilograms.
• It consists of three ocean-observing sensors:
• Ocean Color Monitor (OCM-3): The 13-channel OCM having a spatial resolution of 360 m  and 1400 km swath will observe the day side of the earth every day and will provide crucial data on the distribution of ocean algae, the base of the food chain within the marine ecosystem.
• Sea Surface Temperature Monitor (SSTM): This will provide information about the crucial parameter- ocean surface temperature. The knowledge about temperature will aid in forecasting fish aggregation range, cyclone genesis, and movement.
• Ku-Band scatterometer (SCAT-3): It will ensure high-resolution information about the wind vector like speed and direction at the ocean surface.
• It also consists of an ARGOS payload.
• Though ISRO will be responsible for maintaining the satellite’s orbit and its standard procedures for data reception, the major operational user would be MoES institutions like Indian National Centre for Ocean Information Services (INCOIS), Hyderabad, and National Centre for Medium-Range Weather Forecasting (NCMRWF), Noida.
• The satellite would serve as a strong foundation for India’s blue economy and polar region policies.
• The satellite is also significant as it is the first major ocean satellite launch of India since the initiation of the UN Decade of Ocean Science for Sustainable Development (UNDOSSD, 2021-2030).

Syllabus: GS 3, Science and Technology.

Mains: Developments in the field of Science and Technology; indigenization of technology

Prelims: Ikshak.

Context: Launch of Ikshak.

Details:

• The third of the four Survey Vessels (Large) (SVL) Project- Ikshak was launched for the Indian Navy at Kattupalli, Chennai. It is built by GRSE/L&T.
• ‘Ikshak’ means ‘Guide’. It signifies the contribution of the Survey ships in facilitating safe passage for Mariners at Sea.
• The first of the class ship was ‘Sandhayak’, which was launched on December 2021.
• SVL ships would replace the existing Sandhayak Class survey ships with new-generation hydrographic equipment to collect oceanographic data.
