1. Which rocket was used by ISRO to successfully launch India’s heaviest communication satellite CMS-03?
[A] PSLV-C58
[B] GSLV Mk II
[C] LVM3-M5
[D] SSLV-D2
Show Answer
Correct Answer: C [LVM3-M5]
Notes:
The Indian Space Research Organisation (ISRO) successfully launched the LVM3-M5 rocket from Satish Dhawan Space Centre, Sriharikota at 5:35 pm. The rocket carried CMS-03, India’s heaviest communication satellite weighing 4,400 kilograms. It was the fifth operational flight of the Launch Vehicle Mark-3 (LVM3) launcher. CMS-03 was launched into a Geosynchronous Transfer Orbit (GTO). The satellite will provide multi-band communication services across India and nearby ocean regions. It will enhance secure data, voice, and video connectivity for civilian and strategic applications. The mission highlights India’s capability in heavy satellite launches and strengthens its communication network.
2. What is the primary purpose of the Crew Escape System (CES) developed by ISRO?
[A] To quickly pull the crew module to safety during a launch abort
[B] To monitor weather conditions
[C] To increase rocket speed
[D] To launch satellites into orbit
Show Answer
Correct Answer: A [To quickly pull the crew module to safety during a launch abort]
Notes:
The Indian Space Research Organisation (ISRO) has developed a cost-effective, single-stage test vehicle powered by the Vikas engine. The vehicle is designed to validate the Crew Escape System (CES) for astronaut safety. Crew Escape System (CES) is an emergency escape system that pulls the crew module with astronauts to a safe distance in case of launch failure. The Crew Escape System (CES) is of two types based on the method of extracting the crew module. The Puller type CES pulls the crew module away from the launch vehicle and is used in India’s Gaganyaan mission. The Pusher type CES pushes the crew module away from the launch vehicle using compact, high-thrust liquid-fuel engines and is used in vehicles like SpaceX’s Falcon 9.
3. What is the name of the half-humanoid robot that ISRO will send in December 2025 as part of the first uncrewed Gaganyaan mission?
[A] Aditya
[B] Vyommitra
[C] Kaveri
[D] Talwar
Show Answer
Correct Answer: B [Vyommitra]
Notes:
ISRO Chief V. Narayanan announced that a half-humanoid robot Vyommitra will be sent in December 2025 as part of the first uncrewed Gaganyaan mission. Two more uncrewed missions are planned in 2026 before sending India’s first astronaut, Gaganyatri, to space in early 2027. ISRO successfully conducted the first Integrated Air Drop Test (IADT-01) for the parachute-based deceleration system with support from the Indian Air Force, DRDO, Navy, and Coast Guard. Human Rated Launch Vehicle (HLVM3), Crew Escape System, and propulsion systems have been tested.
4. Consider the following statements about the India Deep Tech Investment Alliance (IDTA):
- It is a public–private fund announced in 2025 to boost deep-tech startups.
- Aims to channel nearly $1 billion, with special focus on semiconductors and AI infrastructure.
- Managed solely by the Department of Space under ISRO.
Which of the above statements is/are correct?
[A] Only 1
[B] 1 and 2 only
[C] 2 and 3 only
[D] 1, 2, and 3
Show Answer
Correct Answer: B [1 and 2 only]
Notes:
The IDTA is a public–private collaborative fund, announced to support deep-tech startups through nearly $1 billion funding, focusing on sectors such as semiconductors and AI infrastructure. It is not managed solely by the Department of Space under ISRO; instead, multiple stakeholders, including industry and private investors, are involved. Therefore, statements 1 and 2 are correct.
5. Which of the following statements correctly describe QpiAI-Indus, India’s quantum computer system?
- It is a 25-qubit full-stack quantum computer launched under the National Quantum Mission.
- It is based on superconducting qubits architecture.
- It was launched in late 2024 as part of ISRO’s Quantum Communication programme.
Select the correct answer using the codes below:
[A] 1 and 2 only
[B] 2 and 3 only
[C] 1 and 3 only
[D] 1, 2 and 3
Show Answer
Correct Answer: A [1 and 2 only]
Notes:
QpiAI-Indus is a 25-qubit full-stack quantum computer launched as part of India’s National Quantum Mission using superconducting qubits technology. It was unveiled in 2025. It is not part of ISRO’s Quantum Communication programme, nor was it launched in late 2024 as described in statement 3.
6. Consider the following statements regarding the PROBA-3 mission:
- It is ESA’s first mission dedicated to precision formation flying.
- The mission involves two satellites simulating a single long structure in orbit.
- Its launch will be carried out using ISRO’s PSLV-XL rocket.
- The primary objective is to test asteroid-deflection techniques.
Which of the above statements is/are correct?
[A] 1, 2, and 3 only
[B] 1, 3, and 4 only
[C] 1, 2, and 3 only
[D] 1, 2, 3, and 4
Show Answer
Correct Answer: C [1, 2, and 3 only]
Notes:
PROBA-3 is the European Space Agency’s first mission for demonstrating precision formation flying, using two spacecraft to simulate an extended structure in orbit. It will be launched aboard ISRO’s PSLV-XL. The mission’s main scientific objective is to provide artificial solar eclipses to study the solar corona, not asteroid deflection. Thus, statements 1, 2, and 3 are correct.
