Consider the following statements: 1. India launched its first full-fledged meteorological satellite (METSAT) in September 2002. 2. For the first time, the space vehicle PSLV-C4 carried a payload of more than 1000 kg into a geosynchronous orbit. Which of these statements is/are correct?
- AOnly 1
- BOnly 2
- CBoth 1 and 2Correct
- DNeither 1 nor 2
Explanation
The correct answer is C because both statements are historically accurate.
Statement 1 is correct. India launched METSAT, its first dedicated meteorological satellite, on September 12, 2002. It was later renamed Kalpana-1 in honor of astronaut Kalpana Chawla. Before this, weather sensors were typically flown as part of the multi-purpose INSAT series.
Statement 2 is correct. The PSLV-C4 mission was significant because it marked the first time the Polar Satellite Launch Vehicle was used to place a satellite into a Geosynchronous Transfer Orbit instead of the usual Low Earth Orbit. The METSAT payload weighed approximately 1060 kg, crossing the 1000 kg threshold for this type of orbit.
