India economy lhahsap jeh in scientist ho natoh toh mehtha adim doh in aum tai. Hetding khat chu India in Space Program dia asuh mang hi 0.004% GDP bou ahi. US, South Korea, China le gamdang ho suhlut sang'a pum niem a niem ahi. ISRO in foreign satellites launch abawl peh nauva invest ijat hamkhat abawl nalai ahi. India scientist ho thilbawl hin ahithei chan'a sum lut lhom le lolhinna dia tohguon ahi. Tu chun chandrayaan-2 sol a um jong hi thao(fuels) lhomcha alutna dia "Slingshot" method kijang a bawl ahi(fig a). Rocket in awl deuva avelkuol jing'a orbit(lampi) dang akhel di phaat le thruster agah peh le orbit dang lut pai² jeng ahi. Hiche hin thao tamtah le sum tamtah adal doh ahi. Chandrayaan-2 hi tupet a 95% successful ahi.Lhanuoi lang(south pole) aphah  kom'a kiholmo chu "Lander" ahi. Hiche hin lha chung'a minerals ho test bawldi kiti ahi."Orbiter" kiti pen chun lha lim akap doh ding ahin;ajouva chu Lander setna chu ahi...

✒Astromuon Kuki Scientific method consists of observation, conceptual ideas, hypothesis, theory, prediction, and experimentation. If the theory doesn't meet with experiments more data should be collected or get discarded  however if the theory satisfy experimentations more predictions will be done. Sciences like chemistry/ biology are confined within a laboratory. Almost all the experiments/observations are carried out inside microscopic level with the help of instruments like microscopes. Errors and limitations can be detected easily in this case. However, in case of astronomy experimentation is done through observation at a distance of light years or astronomical unit between two bodies in a universe with the help of instrument like telescopes.For example, Galileo Galilei was the first person observing the night sky to support the heliocentric model or Copernicus model meaning all the planets revolve around the Sun. Before  widely accepted Heliocentric model by the Cat...

  ~Astromuon Kuki Astronomers use telescopes to learn about the universe. Since the time of Galileo, optical telescopes have grown in aperture from a centimeter to ten meters, and astronomers have put telescopes in space and have used them to detect electromagnetic radiation at wavelengths not visible to the eye.  ADVANTAGES OF LARGE TELESCOPE(HUBBLE TELESCOPE) 1.Hubble made a huge impact discovery that every galaxy in the universe has a supermassive black hole(including our own galaxy-Milky Way) 2.Provided black holes are real 3.Discovered dark energy 4.Found galaxies near the dawn of time 5.Deepest views of the universe 6.Determined the age of the universe. REASONS ASTRONOMERS WANT TO PUT TELESCOPE IN SPACE Due to three limitations imposed on ground based Astronomy. 1.One is caused by light pollution that is omnipresent in urban and suburban areas of the world. 2.The second limitation is the blurring of the Earth's atmosphere. 3.The third limitation is ...
