Q1According to ISRO's PSLV-C61/EOS-09 mission page, which set correctly states three listed key features of EOS-09?
ISRO listed EOS-09 with a Synthetic Aperture Radar payload, 1696.24 kg launch mass and a five-year mission life. The optical-imaging and ocean-colour payload choices replace the listed SAR payload with different Earth-observation payload types, while the 1515 kg and seven-year figures do not match the stated EOS-09 particulars.
Q2Consider the following statements about RISAT-2 as recorded by ISRO in its Earth Observation Satellites listing: 1. Its launch mass is recorded as 300 kg. 2. Its orbit type is recorded as GTO. 3. Its application category is recorded as Earth Observation. Which of the statements given above are correct?
Statement 1 is correct because ISRO records RISAT-2 with a launch mass of 300 kg. Statement 3 is also correct because its application category is Earth Observation. Statement 2 is wrong because the recorded orbit type is SSPO, not GTO. Therefore the correct combination is the one containing statements 1 and 3 only.
Q3According to ISRO's EOS-08 mission overview, which mass and power-generation pair is correct for EOS-08?
ISRO gives EOS-08 a mass of approximately 175.5 kg and power generation of about 420 W. The pair with 320 W understates the power, the pair with 275.5 kg overstates the mass, and the pair with 520 W overstates the power.
Q4Match the fields with ISRO's recorded details for the Cartosat-2 Series Satellite launched on 15 Feb 2017. Fields: launch date, launch mass, orbit type, and application category. Which set is correctly matched?
The correctly matched set is 15 Feb 2017, 714 kg, SSPO, and Earth Observation. The 712 kg mass belongs to a different Cartosat-2 Series entry, 23 Jun 2017 is not the cited launch date for this 714 kg record, and LEO with Disaster Management System and Earth Observation is not the recorded combination for this Cartosat-2 Series Satellite.
Q5According to ISRO's Earth Observation Satellites record, which set correctly describes RISAT-2BR1?
ISRO records RISAT-2BR1 with a launch mass of 628 kg, orbit type LEO, and the application category Disaster Management System and Earth Observation. The 615 kg description belongs to RISAT-2B, the 710 kg SSPO description fits a Cartosat-2 Series entry, and SSPO with only Disaster Management System does not match the cited RISAT-2BR1 record.
