UPSC Practice Questions on ISRO Space Missions

Q1. Recently the XPoSat Mission was in news, it is related to which of the following?
1. India’s first Saturn mission
2. India’s first polarimetry mission
3. India’s first Sun mission
4. Earth Observation Satellite
Answer: Option 2
Solution: The correct answer is Option 2. According to ISRO, XPoSat will study various dynamics of bright astronomical X-ray sources in extreme conditions and will carry two payloads. XPoSat is India’s first and only the world’s second polarimetry mission meant to study various dynamics of bright astronomical X-ray sources in extreme conditions. The other such major mission is NASA’s Imaging X-ray Polarimetry Explorer (IXPE) which was launched in 2021. IXPE carries three state-of-the-art space telescopes. Each of the three identical telescopes hosts one lightweight X-ray mirror and one detector unit. These will help observe polarized X-rays from neutron stars and supermassive black holes. By measuring the polarisation of these X-rays, we can study where the light came from and understand the geometry and inner workings of the light source. The spacecraft will carry two scientific payloads in a low earth orbit. The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarisation).

1. Warbird
2. Saraswati
3. Vimaan
4. Pushpak
Answer: Pushpak
Solution: The correct answer is Pushpak. ISRO successfully carried out the landing mission of its Reusable Launch Vehicle (RLV) named Pushpak at Karnataka’s Challakere. The rocket was launched from the Chalakere Runway, marking the third landing mission of the RLV. An Indian Air Force helicopter carried the launch vehicle to an altitude of about 4.5 km and released it after attaining predetermined parameters. The mission is part of ISRO's efforts to develop essential technologies for a fully reusable launch vehicle, enabling low-cost access to space. The Pushpak RLV is designed as an all-rocket, fully reusable single-stage-to-orbit (SSTO) vehicle, incorporating major elements from various advanced technology demonstrators.

Q7. The major science objectives of Aditya-L1 mission are
i. Study of Solar upper atmospheric dynamics
ii. To demonstrate Safe and Soft landing on Solar Surface
iii. To demonstrate Rover roving on the sun
1. Only iii
2. Only i and iii
3. Only i
4. All of the above
Answer: Only i
Solution: The correct answer is Only i. Aditya-L1 Mission is India's first solar observatory mission launched by ISRO. The objective is to study the Sun, specifically the dynamics of the solar upper atmosphere including the chromosphere and corona. It will be positioned at the Lagrange point 1 (L1), approximately 1.5 million km from Earth, to continuously observe the Sun without interruptions. Statement ii is incorrect as Aditya-L1 is not designed for a soft landing on the solar surface. It is an observational satellite meant to study the Sun from the L1 point. The Sun is a massive ball of plasma with no solid surface, making landing impossible. Statement iii is also incorrect as no rover can operate on the Sun due to extreme temperatures and radiation. Aditya-L1 is purely for solar observation and not for deploying any landers or rovers.
