Chandrayaan 2


Chandrayaan-2, India’s second mission to the moon, will comprise an orbiter, a lander named Vikram [after the father of Indian space programme Vikram Sarabhai], and a rover.

 

It was supposed to be launched on 15 July 2019 at 2:51 IST (14 July 2019 21:21 UTC) but was called off due to a technical snag noticed while filling the cryogenic engine of the rocket with helium about one hour before launch. So the mission was postponed.

The landing site for the Chandrayaan-2 rover is expected to be between the two craters Manzinus C and Simpelius N near the southern pole of the moon.

The orbiter will go around the moon at an altitude of 100 km, acting as a communication relay between the lander/rover and Earth.

The far side of the moon can never be in direct line-of-sight with Earth, proving direct radio communication impossible, which is why the orbiter is needed.

It will carry five instruments: A radar that will probe a few metres below the surface to detect water ice, two spectrometers to study the minerals on the surface, one that studies the lunar exosphere and a camera for geology.

The Vikram lander will perform a soft landing on the lunar surface. It consists of four payloads that will study moonquakes, heat properties of the lunar regolith (soil), the lunar surface charging due to radiation, and measure of electrons in the atmosphere when radio waves pass through it.

The six-wheeled Pragyan rover will be deployed by the Vikram lander soon after landing, and will operate on solar power. It will have two cameras in the front that function as the rover’s eyes: Their combined imaging will provide a 3D visualisation of the path ahead, enabling scientists to plan its next move.

Four of its grooved wheels have independent steering, which will enable them to get unstuck from the lunar regolith. A total of 10 electric motors will help the rover to navigate.

The Chandrayaan mission is completely indigenous, with all parts and payloads developed by India.

What You Observe Depends On How You Observe It.

Suppose you lose your baseball in the woods, and you and your friend decide to look for it. You know that either you will find it, or your friend will (or it will remain lost). Assuming the ball hasn’t been damaged, it won’t be the case that you and your friend each find half of the ball, or that you both find the ball in different locations. There is only one ball, and it has an exact location, even if you don’t know where it is. It can only be found once, and only by one of you. A wave behaves differently, however. Suppose the ball is dropped into the center of a pond, and you and your friend stand on the shore to look for the wave. You can be on one side of the pond, your friend on the other side, and you can both see the wave wash upon the shore. You can even both see the wave wash ashore at the same time, because part of the wave is near you, while another part is near your friend. This is a fundamental difference between particles and waves. Particles are local, with a

Neutron Star

In 1932, the neutron was discovered. As mentioned above, two years later, Walter Baade and Fritz Zwicky at the California Institute of Technology hypothesized stars consisting essentially of neutrons. The idea was that if one compresses a star to a density of 10^14 g cm^-3-the density of the nuclei of atoms we are familiar with then the repulsive force between the neutrons. practically touching one another. would prevent any further compression, and the star will be stable. It is just like packing a football with ball bearings; when the ball is jam-packed. it will be quite incompressible. This hypothesis led physicists to the conclusion that even stars more massive than 1.4M ☉   could find ultimate peace. not as white dwarfs but as neutron stars. A density of 10^14 g cm^-3 implies that such stars would be incredibly small, with a radius of mere 10 kilometres! So it appeared that all stars will find peace after all, either as white dwarfs or neutron stars, but this turned out to

CAN STAR FIND PEACE?

Image
A major problem arose in 1925 when an extraordinary star was discovered. Although it was as massive as Sun, it was only as big as the Earth! This meant that the average density of the star was about 10^6 g.cm^-3 (the mean density of the Sun is only a little more than that of water). The difficulty posed by such a dense star was the following. What will happen to such a star when nuclear energy generation at its center stops? Since the star will no longer produce heat, there will be no force to oppose gravity. What will be the end state of such a star? Surprisingly, the resolution of this problem came from the newly emerging Quantum Physics. In 1926, R. H. Fowler at Cambridge University argued that the star will collapse and collapse till it reaches a density where a new quantum mechanical force provides support against gravity, and the star will at last find peace. This quantum pressure is due to the electrons and arises due to the combination effect of Heisenberg`s principle of
