WHY DID NASA STOP THE MANNED MISSIONS TO THE MOON AFTER APOLLO 17 MISSION IN 1972?

-

    The Mission Apollo 13 accident in April 1970 led to many calls to end lunar missions. Later on, the widespread desire to end Apollo after a successful flight and to counter Soviet claims that robotic lunar exploration was safer, cheaper, and more effective than human lunar exploration helped to prolong the program.

    Astronauts often say the reasons humans haven't returned to the lunar surface are budgetary and political hurdles, not scientific or technical challenges. Private companies like Blue Origin and SpaceX may be the first entities to return people to the moon. However, Landing 14 people on the moon still remain to be one of NASA's greatest achievements of all time history, if not it was the greatest achievement. Astronauts had collected many rocks, took photos, performed experiments, planted some flags, and then came back home on earth. But those week-long stays during the Apollo program did not actually establish a lasting human presence on the moon.


     Many space researchers and entrepreneurs think a manned base on the moon could evolve into a fuel depot for deep-space missions that may lead to the creation of unprecedented space telescopes, and solve many longstanding scientific mysteries about the Universe, Earth, and the moon's creation.
      Besides the reasons of cost-effectiveness and budget factors to stop the manned space missions to the moon, are there any other secret reasons that NASA has been hiding? And, Is it possible that there is some kind of strange Alien contact to crew members of the Apollo space missions which may have created any fear to carry out any further manned space missions to the moon.
        So, what do you think there could be many more of such possibilities? Please leave your comments below.

MOST OUTSTANDING APPLICATIONS OF RAMAN SPECTROSCOPY

    Raman spectroscopy is named after its discoverer ‘Sir Chandrasekhara Venkata Raman’, the great Indian physicist who discovered it in the year 1928. Later on, Sir C.V. Raman received the most prestigious award, the Nobel prize in Physics in the year 1930 for his great discovery of Raman effect . In fact, Sir C.V. Raman was the first Asian to be awarded a  Nobel Prize in all fields of science “for his work on the scattering of light and for the discovery of the Raman effect named after him in 1930.”  He was the second Indian Nobel Laureate but the first Indian scientist to win Nobel prize.  Raman spectroscopy is a Chemical analysis technique that provides detailed information about the molecular structure without causing any physical and chemical changes. It studies the vibrational modes along with translational and rotational modes of the molecule.      Raman spectroscopy works on the principle of Raman scattering. When a monochromatic radiation incident on the sample, the radiatio

DOES THE COSMIC IONIZATION RADIATION EFFECT AIRCRAFTS, AIRCREW, PASSENGERS IN FLIGHTS?

    We are protected from cosmic radiation by Earth’s magnetic field and atmosphere. At higher altitudes in an airplane and particularly when closer to the North and South poles, this protection is less. During a commercial flight, cosmic radiation is several times higher than on the ground thus it increases the high rate of health risks.  Cosmic radiation comes from the sun and outer space and this c osmic radiation makes up about 1/6th of our  exposure to natural radiation.      E veryone, everywhere, is exposed to all kinds radiation like terrestrial radiation, cosmic radiation, man-made radiation and industrial uses like nuclear radiation. Terrestrial  radiation  comes from the Earth: everything is naturally radioactive, including rock, soil, water, air, animals, plants, and food. Its a natural part of the environment in which we live.   The average dose  from terrestrial radiation is 2 mSv(millisieverts) per year. More than half of this is from radon in your home.  People are also

THE JAMES WEBB SPACE TELESCOPE: A TRUE ENGINEERING MARVEL

-

         The  James Webb Space Telescope is the largest and the most powerful space telescope ever built till today.  The interesting fact is that James Webb telescope is very big and its as tall as a 3-story building and as long as a tennis court! It is so big that it has to fold origami-style to fit inside the rocket to launch.  The James Webb Telescope sees the universe in light that is invisible to human eyes. This light is called as   infrared radiation , and we can actually feel it as just heat. The James Webb Space Telescope uses its infrared cameras to see through cosmic dust in our universe. Stars and planets form inside those cosmic dusty clouds, so peeking inside could possibly lead to exciting new discoveries! It will also be able to see objects (like the first galaxies) that are so far away that the expansion of the universe has made their light shift from visible to infrared! Even more interesting fact is that mirrors of this telescope have a thin layer of gold coating th
