Gaganyaan Mission: India’s Historic Leap into Human Spaceflight

  Introduction India is on the brink of making history with its ambitious Gaganyaan Mission , a landmark project by the Indian Space Research Organisation (ISRO) . This mission aims to send Indian astronauts, also known as Gagannauts , into space, making India the fourth nation in the world to achieve human spaceflight, after Russia, the USA, and China. Gaganyaan is more than just a space mission; it is a symbol of India's technological advancement and growing prowess in space exploration. Gaganyaan Mission Mission Overview The Gaganyaan program involves a series of test flights leading up to the final crewed mission , which will carry three astronauts into Low Earth Orbit (LEO) at an altitude of 400 km for three days before returning safely to Earth. The spacecraft will be launched aboard ISRO’s GSLV Mk III (now known as LVM3) , a powerful rocket developed specifically for heavy-lift missions. Objectives of Gaganyaan Demonstrate India's human spaceflight capability by suc...

India Makes History with Chandrayaan-3 Landing on Moon's South Pole

Chandrayaan-3  India made history on August 23, 2023, when its Chandrayaan-3 spacecraft successfully landed on the lunar surface near the south pole. The landing was the culmination of a year-long mission that began with the launch of Chandrayaan-3 on July 14, 2022. The Chandrayaan-3 mission consists of orbitor of chandrayaan-2, a lander and a rover. The lander, named Vikram, is the first spacecraft to land near the moon's south pole. The rover, named Pragyaan, will be deployed from the lander and will explore the lunar surface. The orbiter will remain in orbit around the moon and will provide support for the lander and rover. Lander & Rover The landing of Chandrayaan-3 was a challenging task, as the south pole region of the moon is covered in craters and mountains. However, the Indian Space Research Organisation (ISRO) successfully executed the landing, thanks to the precision of its navigation and guidance systems.This mission will work only for 14 days as one lunar day is eq...

Chandrayaan 3: India's Third Lunar Mission

Chandrayaan 3 On July 14, 2023, India successfully launched its third lunar mission, Chandrayaan 3. The mission is a follow-on to Chandrayaan 2, which was launched in 2019 but failed to land on the moon. Chandrayaan 3 is carrying a lander and rover, which will attempt to land on the lunar south pole. The lander is called Vikram, and the rover is called Pragyan. Vikram is equipped with a number of instruments to study the lunar surface, including a camera, a spectrometer, and a magnetometer. Pragyan is a six-wheeled rover that will be able to travel up to 500 meters on the lunar surface. Structural View The Chandrayaan-3 spacecraft is composed of three main parts: the propulsion module, the lander, and the rover. The propulsion module is responsible for carrying the lander and rover into lunar orbit. It is a box-shaped  structure with one large solar panel mounted on one side and a large cylinder on top (the Intermodular Adapter Cone) that acts as a mounting structure for the ...

Artemis-I : Mission to Moon

Artemis-I   We need to know about why this program called Artemis? Artemis is a mythological Greek Goddess of Moon and twin sister of Apollo. It’s a fitting name for the program that will send the first woman and first person of color to the Moon by 2030. This mission is currently unmanned but crewed spacecraft is under development and ready to carry people in nearly 2026. The spacecraft is named as ORION [ Ocean Research Interactive Observatory Network ]. Artemis-I will orbit the moon about 70000 Km above the moon’s surface. It was firstly launched on 29 August, 2022 but there was any technical issues rises due to this mission postponed and new date of launch are 2 September, 2022 or 5 September, 2022. The Artemis program is a robotic and human moon exploration program led by the United States Space Agency, NASA & involving three other partner agencies : European Space Agency [ESA], Japan Aerospace Exploration Agency [JAXA] and Canadian Space Agency [CSA]. Basically it is a t...

Time Traveling.

Firstly we need to know about time. Time is just a continued sequence of events that occurs in an apparently irreversible succession from the Past, through the Present into the Future. Time is considered as the 4 th dimension in total 11 dimensions. Time travelling mean we have move within the time from present to past or present to future and visa – versa. Time is one of the most unique and interesting topic in our world. Some of the scientist say that time travelling is not possible but some of them do not get agreed that they may consider the time travelling is possible in some way. The brightest minds have been trying to answer this question and formulates the main regularities related to this process for year. Beside the rapid evolution of science and technologies renewed interest in this topic and gave rise to vigorous debates around the possibility and impossibility of time travels. The discovery of wormholes also preconditioned the undying interest in the topic. There are ...

IMAGES CAPTURE BY JAMES WEBB SPACE TELESCOPE

As we all know that on 25 December, 2022 New Space telescope has had be launch known as James Webb space telescope in replacement of Hubble space telescope. It had said some images of different galaxies and other some of the selected image released by NASA on 11 July 2022 the name of these images as follows: 1) SMACS 0723 2) WASP – 96B 3) SOUTHERN RING 4) STEPHEN’S QUINTET 5) CARINA NEBULA => Some detail information about these images : • SMACS 0723 :- This is the first image that released by James Webb space telescope of the deepest sharpest inferred image of distance universe ever produce. This image is of galaxy cluster SMACS 0723 and other thousands of galaxies . The galaxy cluster SMACS 0723 appears here it would have exist 4.6 billion year ago. This is deep field that show the phenomena known as gravitational Lensing in action to study and pressing galaxy is back to the beginning of cosmic time. • WASP-96B :- Webb’s observe hot and puffy planet outside our solar syst...

Lifecycle of a star : Birth to Death

STARS AND PLANETS  Star A star is a luminous and biggest object in the universe that emit light naturally. Sun is also a star. The study of birth , life and death of a stars is called stellar evolution. First stage in the birth of star is called protostar and the death of star is called supernova .  FORMATION OF A STAR BY CLOUD OF DUST How stars are formed ? Stars are made by cloud of gases and dust that scattered throughout the galaxies. The cloud of dust is called the orion nebula . As gravitational force of attraction applied on cloud they collapses and when cloud collapse the material at the center get heat up so that all stars and planet have high temperature at core. A star build by continuous process of gravitational pull cloud collapse to make its size bigger. The size of star (or mass of a star) reaches from  15 to 130 solar masses . At center the temperature gets extremely high, it tigger the fusion reaction. All the material that has fallen in then evolves int...

THE UNICORN : CLOSEST BLACK HOLE TO EARTH

The black hole absorbing light Firstly we need to know about black holes. Black hole are those holes which formed when two stars collapse each other when they live it’s complete life. Only black hole have capacity to absorb light completely without emitting any particle of light. They are small in size as compared to stars but having mass greater than star and also having higher density than a star. THE UNICORN : CLOSEST BLACK HOLE TO EARTH   Sir Tharindu Jayasinghe a doctoral student in astronomy at Ohio state found the closest black hole to the earth. It have nickname “ THE UNICORN ”.  The Unicorn is located about 1500 light years from Earth. This may be the smallest known black hole in ‘ The Milky Way Galaxy ’ and closest to our solar system. The mass of this black hole is 3 solar masses. This black hole is located right next to red giant star called V723 Mon in the constellation of Monoceros. Speed of Unicorn is approx. 1100,000 mph about 230 million light years from Earth...
