6. Consider the following statements regarding the Axiom-4 mission:
- The mission is a private US-based venture aiming to send astronauts to the Moon.
- Shubhanshu Shukla will become the second Indian to go into space, following Rakesh Sharma.
- The mission is scheduled for launch in May 2025.
- The Axiom-4 mission is part of the Gaganyaan program for human spaceflight by ISRO.
Which of the above statements is/are correct?
[A] 1, 2 and 3 only
[B] 2 and 3 only
[C] 2, 3, and 4 only
[D] 1, 3, and 4 only
Show Answer
Correct Answer: B [2 and 3 only]
Notes:
The Axiom-4 mission is aimed at sending astronauts to the International Space Station (ISS), not to the Moon. Shubhanshu Shukla will indeed become the second Indian in space, trailing Rakesh Sharma after around 40 years. The scheduled launch of the mission is in May 2025. The mission is not a part of the Gaganyaan program by ISRO. Hence, answers 2 and 3 are correct.
7. Consider the following statements related to the TV-D2 mission in ISRO’s Gaganyaan program:
- Its purpose is to test the Crew Escape System (CES) during an abort scenario.
- It is designed to launch India’s first human spaceflight into orbit.
- It serves to simulate landing scenarios for Gaganyaan astronauts.
- It is aimed to test the performance of the space station module.
Which of the above statements is/are correct?
[A] 1 and 2 only
[B] 2 and 3 only
[C] 1 only
[D] 1, 2, and 4 only
Show Answer
Correct Answer: C [1 only]
Notes:
The TV-D2 mission under ISRO’s Gaganyaan program primarily aims to test the Crew Escape System (CES) during potential abort scenarios. It does not aim to launch India’s first human spaceflight into orbit (Option 2), simulate landing scenarios (Option 3), or test the space station module’s performance (Option 4). Hence the correct answer is Option 3 (statement 1 is only correct).
It primarily focuses on simulating an abort scenario during the ascent phase of the mission, not specifically landing scenarios.
8. With reference to ISRO’s SPADEX mission, consider the following statements:
- The SPADEX mission was launched using the GSLV Mk III vehicle in December 2024.
- It involves docking and undocking experiments using two small spacecraft.
- The successful demonstration of docking technology is critical for missions like the Bharatiya Antariksh Station.
Which of the statements given above is/are correct?
[A] 1 and 2 only
[B] 2 and 3 only
[C] 1 and 3 only
[D] 1, 2, and 3
Show Answer
Correct Answer: B [2 and 3 only]
Notes:
The SPADEX mission was actually launched aboard the PSLV-C60, not the GSLV Mk III, making option 1 incorrect. However, the mission indeed involves carrying out docking and undocking experiments using two small spacecraft, and the success of such a demonstration is crucial for certain missions like the Bharatiya Antariksh Station, making options 2 and 3 correct.
9. Consider the following future goals of ISRO:
- Construction of Bharatiya Antariksh Station
- Reusable Launch Vehicle (RLV) development
- Human Moon Mission by India
- Chandrayaan-4 robotic rover deployment
Which of these are likely to benefit from the successful SPADEX mission?
[A] 1 and 3 only
[B] 2 and 4 only
[C] 1, 2, and 3 only
[D] 1, 3, and 4 only
Show Answer
Correct Answer: D [1, 3, and 4 only]
Notes:
The successful SPADEX mission is likely to benefit primarily the construction of the Bharatiya Antariksh Station and the Human Moon Mission by India.
These require docking capabilities which the SPADEX mission focuses on.
The development of the Reusable Launch Vehicle (RLV) is about atmospheric flight and landing technology, not docking.
SpaDeX’s success paves the way for future missions like Chandrayaan-4, which aims to return lunar samples to Earth. Also, unless a return or assembly module is involved, a robotic Chandrayaan-4 mission wouldn’t need docking.
10. ISRO recently conducted the second short hot test of the semi-cryogenic engine for which launch vehicle?
[A] Launch Vehicle Mark-3 (LVM3)
[B] SSLV (Small Satellite Launch Vehicle)
[C] NGLV (Next Generation Launch Vehicle)
[D] Polar Satellite Launch Vehicle (PSLV)
Show Answer
Correct Answer: A [Launch Vehicle Mark-3 (LVM3)]
Notes:
The Indian Space Research Organisation (ISRO) has successfully conducted the second short hot test of the semicryogenic engine that will power the Semicryogenic booster stage of the Launch Vehicle Mark-3 (LVM3). A semicryogenic engine uses a cryogenic oxidizer like Liquid Oxygen and a hydrocarbon-based fuel like kerosene. It combines the advantages of cryogenic and conventional engines, offering better efficiency and operational simplicity. In comparison, a fully cryogenic engine uses both fuel and oxidizer in liquid form, like Liquid Hydrogen and Liquid Oxygen, giving 100% efficiency without causing greenhouse gas emissions. This successful test marks a key step towards upgrading LVM3 for future heavy-lift missions.
