What is SpaceX?                SpaceX is an American private space agency founded by Elonmusk ,who was the founder of Tesla cars, neural link. He started this company on 2002 with few members and now SpaceX is one of the most successful company around the world. Elon musk-The founder of SpaceX                  SpaceX designs, manufactures and launches advanced rockets and spacecraft. The main thing is that they use recyclable combustion engines and thurster which reduces more money, this attract the business  Why NASA astronauts on SpaceX?   HISTORY :               Over a decades  NASA sends astronauts to space by their own space shuttle but  Since July 2011,NASA sends astronauts by Russian rockets to ISS, because the NASA not like to invest more money to sends astronauts to ISS,over a past NASA uses space shuttle to send the astronauts to ISS   NASA's Space Shuttle               S huttles transported American astronauts into space for three

Massive telescope on far side of moon:                   NASA announced to build a massive powerful telescope and they planned to construct inside a natural creator on moon's far side and NASA funding early stage proposal About Moon's surface:                 Normally Moon orbit earth once every 27 days and it doesn't rotate itself like the Earth due to tidal lock ,so you are seeing same side of the moon and over a century we have a observed and discovered a lot of information about Moon's one side                   The far side of the Moon is away from Earth.So it's hard observe the other side             The first image of other side is photographed by the Soviet Luna 3 spacecraft in 1959.The Apollo 8 astronauts were the first humans to see the far side in person when they orbited the Moon. First image of far side of moon by luna 3                     The dark side of the moon contains a lot of creators Spacecraft to dark side:          

How to capture stars:             To do this you need a camera  mobile which has a features like pro mode,manual mode or expert mode,this helps to change camera settings         Go to pro mode or manual mode or expert mode and change the ISO value to 200            Now enable focus mode or auto focus mode upto the maximum     Change the shatter speed to the maximum value in your mobile phone            Use tripod or stand and place  mobile towards the sky and capture the image        But if you are living in a city it is difficult to capture the image because of light pollution                                 The below images were captured in realme 3 pro   

Why starlink?           The SpaceX , founder Elon Musk introduce this mission Starlink.The aim of this mission is to provide continues internet globally with low letancy at speed but how? How starlink works?           Now you are reading this blog through your mobile or PC which is connected to internet,this internet you are getting is through cable providers or satellite communication.But cables are much cheaper and faster than satellite communication then why Elon Musk plans satellite connection. When you use the internet through satellite communication,it produce 0.5 second letancy because these satellites are orbit around Earth at 22,000 to 35,000 km from the Earth surface and these are called as geostationary satellite How Elon Musk plans?            To reduce the latency mentioned above,the satellites will place in low Earth orbit because at Geostationary orbit it is difficult to connect the signals from satellite because it moves to some other place and the connecti

Researchers have found the world's oldest material found on earth              An Meteorite fell in Australia in 1967 is officially become the world's oldest material which was formed between about 5-7 Billion years old and this is older than our solar system. This stardust helps to understand about milkyway,stars, planets,etc in space science. It contains tiny dust grain particles which is known as "pre solar grains" and 60% of them are 4.5-4.9 billion years old and 10% of them are 5.6 billion years old and 30% of them are about 7 billion years old and even our solar system is 4.5 billion years old,this material is formed before the formation of our solar system. Researcher predicted that this is a part of star and Stars born when bits of dust and gas floating through space locate one another and collapse in on one another and heat up. They burn for millions to billions of years, and then they die. When they die, they pitch the particles that forme

Landing today:                  Chandrayaan-2's landing module 'Vikram' will land on moon between 1:30 am - 2:30 am.                    Rover rolled out between  5:30 am- 6:30 am and it takes photo and send it to ISRO.                     A successful landing will make India the fourth country after Russia, the US and China to achieve a soft landing on the moon.                     Over make countries try to make a soft landing and most of them were failed. And this is one of the risky and the 1st country to land on dark side of the moon.                                   Star and Disney India will live telecast India's mission to moon on September 6 at 11:30 pm. The milestone event will be telecasted live on National Geographic, Star Plus and Star Bharat.

Military fores on Amazon:                            Brazil's President is Sending the Military fight to the Amazon Fires as protests grow worldwide.                                        Military Aircraft, 40,000 Troops Pressed into Action to Fight Massive Amazon Forest Fires                                               And American president Donald Trump said that the United States can help with the Amazon Rainforest fires
