NASA on Wednesday celebrated the fifth anniversary of their Solar Dynamics Observatory (SDO) and thus released a incredible time-lapse video showing the amazing changing surfaces of Sun from June 2010 to February 2015 of a period of 5 years. These three minute video will show you the various activities happening in the Sun like  dancing giant loops, hovering in the Corona and solar flares hurled into space, energy and X-rays. In this video, Sun is shown changing colour which is caused by the different wavelength emerging from the Sun.  The splendid video was created by capturing the image of Sun every 8 hours for a time period of 5 years and presenting in a time-lapse. Time lapse video created by NASA by the image captured by SDO in 5 year period.

Reusable space vehicle is the future of space travel . Lots of space organisation around the world like NASA of USA, SPACE-X, ESA, ISRO and lot more are working to built and upgrade the spaceplane that can be used multiple times. European Space Agency has built his own reusable spaceplane called IXV that can be used multiple times.  On 11 February, 2015 the IXV has completed a 100-minute mission. IXV has been launched from the Europe's Spaceport in Kourou, French Guinea. After reaching at a altitude of  211 miles from the Earth surface, IXV got separated from the Vega rocket and continued upward to 256 miles into the thermosphere. It then fell back to Earth reentering atmosphere at a altitude of 74.6 miles and a speed of 4.7 miles per second. The 300 sensors abroad the IXV recorded valuable data that the ESA will use to guide further future vehicles design. Intermediate eXperimental Vehicle or IXV is a spaceplane by European Space Agency launched abroad a Vega rocket. The spac

Hypersonic  travel seems to be impossible now a days, but it be possible after 10-15 years from now on. Scramjet (supersonic combusting ramjet) is similar to Ramjet except in this combustion takes place in supersonic airflow. Unlike the Ramjet, in which air was decelerated at subsonic velocity to be combusted; Scramjet combusts the air in supersonic speed which give Scramjet very high speed, in the range of MACH 12(14000 km/hr) to MACH 24(25000 km/hr). Working of a Scramjet engine Scramjet like any other jet engine , uses fuel and oxidiser to protect thrust. The design of Scramjet consists of a converging inlet, in which incoming air is compressed using high pressure in front of it; a combustor ; and a diverging nozzle to produce accelerated thrust. Scramjet like Ramjet does not use any rotating parts, therefore it require high kinetic energy of hypersonic flow to compress the incoming air ; and must be accelerated to high velocity, like Mach 4. Due to supersonic flow of air, f

United Nations has declared the year 2015 as the International Year of  Light. Chandra X-ray Observatory was launched by NASA on July 23, 1999 to study the stars and galaxies in the universe. It was previously known as Advanced X-ray Astrophysics facility but later changed in honor of Subrahmanyan Chandrasekhar. It was specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes.   Top games Chandra X-ray Observatory study the X-ray sources coming from far away galaxy which do not enter the Earth atmosphere. By using the X-rays images from the Chandra observatory, scientists understand the structure and evolution of the universe. X-ray telescope uses a Wolter telescope consisting of nested cylindrical paraboloid and hyperboloid surfaces coated with gold and iridium, as X-rays would be absorbed by normal mirrors. Chandra is one of the farthest satellite in the Earth orbit. Chand

Ever thought of travelling at a speed of more than 7000 km/hr . Flying at supersonic and hypersonic speed is need of the present world and the dream that every aeronautical engineers want to be true. But now, hypersonic and supersonic travel is not a dream but a reality. With the use of Ramjet and Scramjet engine hypersonic travel are possible. Ramjet and Scramjet works on a same principle with similar design, differing only on the method of combustion of air. Ramjet slow the air to subsonic flow before combusting  while Scramjet combust it at supersonic flow. Also referred to as flying stovepipe, Ramjet engine can operate upto speed of MACH 6 (7350 km/hr). Ramjet engine is different from the turbojet engine as it compresses air without using a rotary compressor. Ramjet are used in missiles, artillery shells, supersonic aircraft that require a small and simple mechanism to acquire high speed.  Ramjet has a disadvantage that it cannot work on a low velocity means that it canno

China  is planning to mine moon for helium-3 fusion fuel. After the successful  lunar probe Chang ‘e ,china is going a bit ahead. Chang’e mission was very successful  for china to explore moon, but now with the Chang 5, china will bring the first sample of fusion-ready helium-3. Helium-3  is best to be used as a fuel in nuclear fusion as no neutrons is generated as a reaction product. The protons generated will have some charge which can be controlled and contained using electromagnetic  fields. Moon has said to have a depot of atleast 5 million tons of helium-3 on its top surface level,  whereas earth rarely have it. But it is still a lot of year ahead and it will be very difficult to do it  and will require a lot of manwork .

NASA has teamed up with Microsoft to develop a new software that will enable scientists to work on Mars virtually using a wearable technology called Microsoft HoloLens. The software called OnSight, developed by Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, will give researchers a means to plan and, along with the Mars Curiosity rover, conduct science operations on the Red Planet. OnSight will give rover scientists the ability to walk around and explore Mars right from their offices. OnSight will use real rover data and extend the Curiosity mission’s existing planning tools by creating a 3D simulation of the Martian environment where scientists around the world can meet. Program scientists will be able to examine the rover’s worksite from a first-person perspective, plan new activities and preview the results of their work firsthand. Until now, rover operations required scientists to examine Mars imagery on a computer screen and make inferences about what they are see
