For interplanetary missions, spacecrafts-satellites have to communicate with each-other or earth-based control centers through large distance in space. Sometimes, due to certain reasons, the communication links breaks and the transferred data is lost. NASA is working on a new innovative technology....

NASA is working on a new super-heavy-lift launch vehicle called Space Launch System or SLS. The Space Launch System will be used to launch the Artemis I, the mission to go back on moon (Artemis is the twin sister of Apollo).The SLS will produce around 8.8 million pounds of thrust during initial stage at lift-off, becoming....

On 30th July, 2020 NASA has launched its new mission to mars, called the Perseverance mission. The Mars Perseverance rover was launched toward the Red Planet at 7:50 a.m. EDT ( 11 : 50 GMT ), riding an Atlas V rocket into space from Cape Canaveral Air Force Station in Florida. Here are five interesting.....

SpaceX is working on a next generation space launch vehicle called Starship spacecraft and Super Heavy rocket, collectively referred to as Starship. This is a fully reusable transportation system designed ofr missions to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. SpaceX claims that it will be world's most.....

NASA has started to work on a new mission to send a 2.5 meter ( 8.4 foot ) telescope into the stratosphere on a balloon, the size of a football stadium. The mission ASTHROS or Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths is sheduled to launch in.....

RADAR or Radio Detection and Ranging is a primary threat detection and guidance system of any armed forces for safeguarding the airspace as well as for sea surface area. Radar basically transmits radio waves or microwaves and when the waves hit a body like an aircraft, missile or a ship and comes back after reflection, the receiver receives it and gets.....

If “Necessity is the mother of invention” then, “War is the mother of civilization.” The fact that humans came together and formed a clan in prehistoric times is because they had to fight against vicious animals for survival. Humans would not have to be civilized if they did not need to fight war against those creatures as well as nature. War created the necessity......

Air defence is one of the important factors for national security of a country. In a world where even terrorist organizations have lethal missiles, rouge countries with nuclear missiles aneffective air defence system becomes a necessity. When it comes to airspace defence, the main focus is on ground based air defence systems. In this blog I will discuss India's......

Machine learning provides computers with the ability to learn without being explicitly programmed. Machine learning is a way of making machines learn, very much similar to the way humans learn.Imagine a child is asked to fit wooden blocks into correctly shaped slots. He starts off by picking up the square block and sticking it into the circular hole.....

Chandrayaan 2 is the second lunar mission being conducted by Indian Space Research Organization. The first mission was Chandrayaan 1 (22 Oct 2008-28 Aug 2009) which was a successful mission. Chandrayaan 1 orbiter was the first manmade lunar orbiter to find water on the moon. It was because of Chandrayaan 1 mission, India built its deep space network......

As per 2019, almost every modern military forces in the world uses unmanned aerial system or ‘Drones’. Sometimes they are used for information gathering, spying and sometimes for combat purposes. They are very much effective, reliable and safe. Now the question comes, will these drones replace fighter jets in distant future ? Let’s find out.....

Probably you are interested in time traveling, yes, we all are. In reality, technically, we all are time travellers. Because as a matter of fact, time works at different speeds for different gravitational field. In other words, if a person is at sea level and another person is atop of a mountain, then for them time will pass at different speeds. But this difference will be so small ( probably billion billion times....

On March 27, 2019 India successfully test fired an ASAT ( anti-satellite ) missile, destroying a LEO ( low earth orbit ) satellite at 283 km above earth surface which is code named as ‘ Mission Shakti ’. This puts India an elite league of four countries in the world who have successfully conducted such kind of experiment. Yesterday’s three dimensions of war of war vs todays five dimensions of war....

At the start of the nineteenth century, only gas and oil lamps were to be found in homes and businesses, communications took the form of handwritten letters that took days to travel across the country, and several weeks across oceans. But by the end of the century electric light bulbs were common. By 1865, a telegraph cable connected the United States and ....

You probably check your phone, and maybe turn on the toaster? Well, both of those are out of the picture in a world without transistors. You’d have to make your toast the old fashion way....

Since the early days of space exploration robots are used a key tool to collect data and perform experiments in outer space. From lunar rover to mars rover, space agencies like NASA, ROSCOSMOS etc. used them for collecting samples from the lunar or martian surface and analyze them to know more about them as well as our solar system. Today we are gonna....
