Which of the following statements are true about crew selection and training for “Gaganyaan Mission”? (i) Crews are selected after clinical, psychological and aeromedical examination.
(ii) Mission-specific training will be conducted at ISRO, Trivandrum.
(iii) Selected astronauts will undergo their generic spaceflight training in Yuri Gagarin Cosmonaut training centre, Russia.
The Gaganyaan mission is India's ambitious human spaceflight program. Selecting and training the astronauts (Gaganauts) for this mission is a crucial and multi-stage process. Let's evaluate the given statements regarding crew selection and training for the Gaganyaan Mission to determine their accuracy.
We will examine each statement individually:
Selecting individuals for spaceflight requires them to be in peak physical and mental condition. Astronaut selection programs worldwide involve rigorous medical check-ups (clinical and aeromedical) to ensure candidates can withstand the harsh environment of space, including g-forces, radiation, and microgravity. Psychological evaluations are also vital to assess mental resilience, ability to work under pressure, and teamwork skills. This statement aligns with standard astronaut selection protocols.
Analysis: This statement is true.
ISRO has multiple centres, each specializing in different areas. Trivandrum primarily houses the Vikram Sarabhai Space Centre (VSSC), which focuses on rocket design and development. While VSSC plays a vital role in Gaganyaan by developing the launch vehicle (GSLV Mk III), the primary centre for human spaceflight activities, including astronaut training and mission control, is the Human Space Flight Centre (HSFC) located in Bengaluru. Mission-specific training, involving simulations of the spacecraft and mission phases, is conducted at HSFC and other specialized facilities.
Analysis: This statement is false. Mission-specific training is primarily conducted at HSFC, Bengaluru, not VSSC, Trivandrum.
India collaborated with Russia for the initial phase of astronaut training for the Gaganyaan mission. The selected astronaut candidates underwent generic spaceflight training, including subjects like spacecraft systems, flight dynamics, and physical conditioning adapted for space, at the Yuri Gagarin Cosmonaut Training Centre (GCTC) in Star City, Russia. This training centre has a long history of training cosmonauts for various missions.
Analysis: This statement is true.
Based on the analysis:
Therefore, the statements that are true about crew selection and training for the Gaganyaan Mission are (i) and (iii) only.
| Statement No. | Statement | Truth Value | Reasoning |
|---|---|---|---|
| (i) | Crews are selected after clinical, psychological and aeromedical examination. | True | Standard and essential part of astronaut selection process. |
| (ii) | Mission-specific training will be conducted at ISRO, Trivandrum. | False | Mission-specific training is primarily at HSFC, Bengaluru. |
| (iii) | Selected astronauts will undergo their generic spaceflight training in Yuri Gagarin Cosmonaut training centre, Russia. | True | Initial generic training was conducted in Russia. |
| Aspect | Details |
|---|---|
| Selection Process | Includes clinical, psychological, and aeromedical examinations. |
| Generic Training Location | Yuri Gagarin Cosmonaut Training Centre, Russia (initial phase). |
| Mission-Specific Training Location | Human Space Flight Centre (HSFC), Bengaluru, India. |
The Gaganyaan project aims to demonstrate India's capability to send humans to Low Earth Orbit (LEO) on an Indian launch vehicle and bring them back safely to Earth. Key aspects include:
Understanding these details helps clarify the process of preparing for India's first human spaceflight mission, Gaganyaan.
A stone is thrown horizontally from the top of a 20 m high building with a speed of 12 m/s. It hits the ground at a distance R from the building. Taking g = 10 m/s2 and neglecting air resistance will give :
A sphere of volume V is made of a material with lower density than water. While on Earth, it floats on water with its volume f1V (f1 < 1) submerged. On the other hand, on a spaceship accelerating with acceleration a < g (g is the acceleration due to gravity on Earth) in outer space, its submerged volume in water is f2V. Then:
A railway wagon (open at the top) of mass M1 is moving with speed v1 along a straight track. As a result of rain, after some time it gets partially filled with water so that the mass of the wagon becomes M2 and speed becomes v2. Taking the rain to be falling vertically and the water stationery inside the wagon, the relation between the two speeds v1 and v2 is :
Consider the following statements:
1. Distance between the longitudes becomes zero on North Pole and South Pole.
2. Distance between the longitudes is maximum on the Equator.
3. Number of longitudes is more than number of latitudes.
Which of the statements given above is/are correct?
One block of 2⋅0 kg mass is placed on top of another block of 3⋅0 kg mass. The coefficient of static friction between the two blocks is 0⋅2. The bottom block is pulled with a horizontal force F such that both the blocks move together without slipping. Taking acceleration due to gravity as 10 m/s2, the maximum value of the frictional force is :
