Answers & Solutions

The answers given below are the ans. accepted by the examiners on the basis of what was written. Most of these were not predetermined, & allowances have been made for the use of logic & reasoning:


Q1. What is the ideal shape for a space settlement? Explain with reasons.
Ans. Torus/Toroid/Ring, Ellipse/Ellipsoid, Sphere, Cylinder, because the pseudo-gravity will be uniform along    the surface. Also they have a good volume/area ratio.

Q2. What are the effects of micro-g on human body? How will u induce gravity?
Ans. Muscles & bones weaken, circulation affected, height increases, head swells up.
        Gravity can be induced by rotating settlement & centrifugal accn. will act outwards.

Q3. What are the possible hazards for a space settlement?
Ans. Asteroids, space junk, radiation.

Q4. Suggest systems of computing.....
Ans. Ideal ans.-Cloud Computing, Quantum Computing
        But given ans. like nanoech, carbon nanotubes accepted

Q5.  If space sett. is around Mars, where to get resources?
Ans. Mars, Phobos, Deimos, Asteroids(give details of what resources from where)

Q6.  How to induce Earth-like conditions?
Ans. Day-night cycle, climate cycles(seasons), recreation, flora & fauna.

Q7.  Before the ISS there was Mir which held the record.

Q8.  Why don't metallic objects stick to ground due to magnetic field of earth?
Ans. Field intensity & strength too less. Strength= 30-60microtesla.

Q9.  What would happen to Earth if the Sun was to disappear at this moment?
Ans.  There would be no change for 8 mins. 17 secs. as information travels at speed of light. After this Earth   would move off at a tangent to its orbit.

Q10. Sequence ques.
Ans. 96 . The logic was that 10 is largest no. with 3 letters in name, 9 is largest with 4 letters in name & so on.
Q11. Describe LHC experiment & .....
Ans. Protons projected at 99.97% speed of light & made to collide in search of Higgs Boson, the particle thought to give matter property of mass.

Q12. Terraforming.
Ans. Transforming the conditons on a planet to mimic Earth, to enable colonisation.
(Formation of artificial soil or terrain not acceptable)

Q13. Baiknur Province, Kazakhistan.
Ans. Site frm where first man in space (Yuri Gagarin) was launched.

Q14. Successor to Hubble Space Telescope.
Ans.  James Webb Space Telescope.

Q15. Geocentric(Earth-Centred) theory.
Ans. Ptolemy

Q16. Celestial body with period 76 years. Year 1986, probe sent.
Ans. Probe: Giotto
        Celestial Body: Halley's comet

Q17. "The spaceship proceeded at the speed of light  to the planet at the centre of the planetary nebula".
Ans. Nothing can move at speed of light.
        No planet at centre of planetary nebula (such nebulae do exist, but they have core of dead star(white dwarf) at centre)

Q18. Famous astronomer, comet, crater, ashes on moon.
Ans.  Gene Shoemaker.

Q19. Comet named after him?
Ans. Shoemaker Levy 9 crashed into Jupiter, damaging areas the size of Earth.

Q20. Accelerating in orbit.
Ans. Always accelerating, but if tangential accn., then eccentricity of orbit increases.

Q21. What is gravity? Y do planets revolve?
Ans. Warping of spacetime continuum, due to presence of mass. Revolution due to  planet trying to escape the Sun's gravity well.

Q22. Spacewalk.
Ans. Action-Reaction principle applies on connection with spacecraft(push or pull rope) & pushing or pulling parts of spacecraft.
