  NISAR The NASA-ISRO Synthetic Aperture Radar (NISAR) mission is a joint project between NASA and ISRO to co-develop and launch a dual-frequency synthetic aperture radar on an Earth observation satellite. The satellite will be the first radar imaging satellite to use dual frequencies. It will be used for remote sensing, to observe and understand natural processes on Earth. With An estimated total cost of US$1.5 billion, NISAR is likely to be the world's most expensive Earth-imaging satellite.   OVERVIEW The satellite will be 3-axis stabilized. It uses a 12 m extendable mesh antenna and operates in both the L and S microwave bands. The aperture grid reflector (antenna) is supplied by Northrop Grumman's Astro Aerospace. The satellite will be launched from India aboard a GSLV in Q1 of 2024. The orbit will be a Sun-synchronous, dawn-to-dusk type. The planned mission life is three years. The project has passed the first stage of the design v...

  What is 'Fixed Mindset' ? A fixed mindset, proposed by Stanford professor Carol Dweck in her book  'Mindset' , describes people who think their qualities as fixed traits that cannot be changed, have fixed mindset. With a fixed mindset, talent is enough to lead to success and effort to improve these talents isn’t required one is born with a certain amount of skill and intelligence that can’t be improved upon. Those who hold a  fixed mindset  believe that they are either good or bad at something based on their inherent nature.Those with fixed mindsets may avoid challenges, give up easily and ignore useful negative feedback. The opposite of this fixed mindset is the 'growth mindset'. What is 'Growth Mindset' ? A growth mindset, also proposed by Stanford professor Carol Dweck, describes people who believe that their success depends on time and effort.  People with a growth mindset feel that through hard work and perseverance they ...

   Is time travel possible ? Yes time travel is a real thing indeed! A century ago, a popular scientist with a big head in the name of Albert Einstein came up with an idea about how time works. He called it 'relativity'. This theory states that time and space are connected. He also said, nothing can travel faster than light, which was later proved wrong, since our universe itself expands faster than light. Well, according to this theory, the  faster  you travel, the  slower  you experience time. Scientists have done some experiments to show that this is true.   T here was an experiment that used two clocks, which were set to the exact same time. One clock stayed on Earth, while the other flew in an airplane.  After the plane flew around the world, scientists compared the two clocks. The clock on the fast-moving aircraft was slightly behind the clock on the ground. So if you could travel at the speed of light,...

The Plan  The FBI were aided by Allan West, who didn't make it out of his cell and began providing them the details. The men concealed their absence while working outside their cells—and after the escape itself—by sculpting dummy heads from a hand-made paper mixture of soap, toothpaste, concrete dust, and toilet paper, and giving them a realistic appearance with paint from the maintenance shop and hair from the barbershop floor. With towels and clothing piled under the blankets in their bunks and the dummy heads positioned on the pillows, they appeared to be sleeping.  They also assembled a six-by-fourteen-foot rubber raft, the seams carefully stitched by hand and sealed with heat from nearby steam pipes. Paddles were improvised from scrap wood and screws. The Escape   On the night of June 11, 1962, after all the preparations were made, the men began planning. West found that the cement used to reinforce the collapsing concrete around the vent had hardened, n...

Click here for Part 1 Preface There was widespread protest against the Townshend Acts. Boston merchants boycotted British goods. Soon the o ther colonies joined the protest. The women formed their own organization called the " Daughters of Liberty". Boston Massacre The British mobilized more troops to encounter the protests. This enraged the people further and many people joined the protest. In March 1770, the local people started to throw snowballs on the British troops, but the British retaliated with bullets. Five civilians were killed. The patriots pressed throughout the colonies declared the Boston Massacre, an unwarranted crime committed against the people of Boston, by the cruel British. The wrath continued to grow, the colonists set their sight on the remaining tax on tea. Boston Tea Party On December 16th a band of patriots know as the "Sons of Liberty" disguised themselves as Native Americans, and marched down to the Boston Harbour, and boarded a Briti...

Introduction The American Revolutionary War, also known as The American War of Independence or T he American Revolution (1775–83), is a rebellion that led 13 of Britain's North American colonies to political independence and formed the United States. The war followed the expansion of alienation for more than a decade between the British Crown and its large and influential segment of the North American colony. Until early 1778, the conflict was a civil war within the British Empire, but then when France (1778) and Spain (1779) joined the colony against Britain, it became an international war. From the beginning, naval power was extremely important in deciding the course of the war. The Navy provided flexibility to British strategy, offsetting a relatively small number of troops sent to the United States and ultimately enabling the French to help the US bring about the final British surrender at Yorktown. Colonies of the European Powers The European Powers, The ...
