NASA Planet Hunter on Its Way to Orbit

NASA’s Transiting Exoplanet Survey Satellite (TESS) launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life.
TESS, which is expected to find thousands of new exoplanets orbiting nearby stars, lifted off at 6:51 p.m. EDT Wednesday on a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida. At 7:53 p.m., the twin solar arrays that will power the spacecraft successfully deployed.
“We are thrilled TESS is on its way to help us discover worlds we have yet to imagine, worlds that could possibly be habitable, or harbor life,” said Thomas Zurbuchen, associate administrator of NASA’s Science Mission Directorate in Washington. “With missions like the James Webb Space Telescope to help us study the details of these planets, we are ever the closer to discovering whether we are alone in the universe.”

Over the course of several weeks, TESS will use six thruster burns to travel in a series of progressively elongated orbits to reach the Moon, which will provide a gravitational assist so that TESS can transfer into its 13.7-day final science orbit around Earth. After approximately 60 days of check-out and instrument testing, the spacecraft will begin its work.
“One critical piece for the science return of TESS is the high data rate associated with its orbit,” said George Ricker, TESS principal investigator at the Massachusetts Institute of Technology’s (MIT) Kavli Institute for Astrophysics and Space Research in Cambridge. “Each time the spacecraft passes close to Earth, it will transmit full-frame images taken with the cameras. That’s one of the unique things TESS brings that was not possible before.”
For this two-year survey mission, scientists divided the sky into 26 sectors. TESS will use four unique wide-field cameras to map 13 sectors encompassing the southern sky during its first year of observations and 13 sectors of the northern sky during the second year, altogether covering 85 percent of the sky.
TESS will be watching for phenomena called transits. A transit occurs when a planet passes in front of its star from the observer’s perspective, causing a periodic and regular dip in the star’s brightness. More than 78 percent of the approximately 3,700 confirmed exoplanets have been found using transits.
NASA’s Kepler spacecraft found more than 2,600 exoplanets, most orbiting faint stars between 300 and 3,000 light-years from Earth, using this same method of watching for transits. TESS will focus on stars between 30 and 300 light-years away and 30 to 100 times brighter than Kepler’s targets.
The brightness of these target stars will allow researchers to use spectroscopy, the study of the absorption and emission of light, to determine a planet’s mass, density and atmospheric composition. Water, and other key molecules, in its atmosphere can give us hints about a planets’ capacity to harbor life.
“The targets TESS finds are going to be fantastic subjects for research for decades to come,” said Stephen Rinehart, TESS project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It’s the beginning of a new era of exoplanet research.”
Through the TESS Guest Investigator Program, the worldwide scientific community will be able to conduct research beyond TESS’s core mission in areas ranging from exoplanet characterization to stellar astrophysics, distant galaxies and solar system science.
TESS is a NASA Astrophysics Explorer mission led and operated by MIT and managed by Goddard. George Ricker, of MIT’s Kavli Institute for Astrophysics and Space Research, serves as principal investigator for the mission. TESS’s four wide-field cameras were developed by MIT’s Lincoln Laboratory. Additional partners include Orbital ATK, NASA’s Ames Research Center, the Harvard-Smithsonian Center for Astrophysics, and the Space Telescope Science Institute. More than a dozen universities, research institutes and observatories worldwide are participants in the mission.

ISRO to launch its Navigation Satellite

After losing contact with its high power S-band communication satellite GSAT-6A within 48 hours after launch, Indian Space Research Organisation (ISRO) is planning to launch its navigation satellite IRNSS-1I on April 12.

The satellite will be launched aboard Polar Satellite Launch Vehicle C-41 (PSLV C-41) rocket from the First Launch Pad (FLP) of Satish Dhawan Space Centre in Sriharikota.
IRNSS-1I will replace faulty IRNSS-1A navigation satellite, whose three Rubidium atomic clocks had stopped working two years ago.
The upcoming launches like of IRNSS-1I will not be affected because of the snapping of signal link with communication satellite GSAT-6A," ISRO chairman Dr K Sivan as saying.
ISRO tried to launch IRNSS-1H to replace faulty IRNSS-1A on August 31 last year, but the satellite got stuck in the heat shield of the PSLV rocket during the launch.IRNSS-1I is the eighth satellite to join the NavIC navigation satellite constellation. The satellite weighs 600kg (dry mass) with a life span of 10 years.The Indian space scientists and engineers are still trying to establish a link with the communication satellite GSAT-6A, which was launched on March 29, using Geosynchronous Satellite Launch Vehicle (GSLV-F08) rocket.

Parallel Universe Decoded

Space has fascinated mankind since long. With the advent of technology, we constantly get to know the answers to our impending question which have baffled us since long. The dark, mysterious space has generated curiosity since forever. With various missions, expeditions taking place every now and then have tried to quench out curiosity thirst. But some questions are still there yet to be answered. The thought of is we alone in this universe has made many scientists sleep less. With every possible effort to find a cure in this path, we still are just clueless. Yet the internet has somehow found its answer, viral answers though.

Recently a viral news did its round on net exclaiming first ever evidence of another life in a parallel universe. The recent viral hit came from a press release of the Royal Astronomical Society. The study details the possible origins of a cold spot found in the data probing of cosmic microwave background. This relates to the leftover heat from the moment the universe was formed after the big bang. Some possible definition of this cold spot is the result of the collision of two universes slamming against each other billions of years ago. The press release states that the cold spot found could be a result of the collision of between two universes. If the further detailed study is to be done and some new researched are to be found which support this reason could be the next big step in the mankind’s search for a parallel universe and other life.

There may not be tonnes of evidence to prove such claims due to our limited approach and technology which has limited our reach in the space related issues, although these finding may or may not have its true basis of authenticity. This press release was supported by just one man and his study and hence can't be termed credible to reach to any point. None the less, such findings keep cropping up every time till the time someone renowned refutes them. At last, all we can hope is that whatever we come through be of use to us and not harm us.

Need To Watch Out For ISRO

While ISRO still has a long way to go in the global competition, yet it has been generating positive buzz for itself with its groundbreaking invention which yet put India back again on the global map. India stands apart from other big players. Unlike other countries who carry out such researchers for national purposes, whereas India aims to create newer technology development. Being India's pride, it is in the process of building new and more powerful rockets. The organisation has its eye set towards being counted in the elite ranks of space agencies. Here is few new work on whom we should keep a tab upon.

 1. On June 5 India launched the heaviest yet the best ever GSLV MK III satellite by the name of THE FAT BOY. The powerful rocket has the next generation technology and can carry a huge sum of 640 tonnes setting it at par against previous editions.
2. India's Mars mission: the ISRO’s Mars mission was a huge milestone the red planet in 2014.  By successful launch and work of Mangalyaan propelled the country's reputation. It is still going strong in Mars orbits gathering information and images.
3. India's rocket launched a record number of satellites: an ISRO aircraft recently blew all the existing records by carrying a record number of 104 satellites in a single journey thus achieving another milestone. The polar satellite launch vehicle beat the previous record of 37 satellites by a Russian rocket in 2014. The PSLV launch brought 88 small satellites to orbit for the silicon valley based earth monitoring company planet along with an earth gazing satellite solely for India.
4. ISRO’s second moon mission: India is all set to launch its second moon mission in 2018. The Chandryaan2 named after its predecessor is planned to go to the lunar surface and collect samples of its dirt.
5. ISRo’s robot on Mars and flight to Venus: ISRO is planning to set its robot on Mars surface and then an expedition to Venus in around 2020’s.  The Mars mission is focused on building a lander and safely bringing it to the Mars surface. The mission involves many complexities hence scientists are preparing and planning to make it a successful one.

Ground Breaking Milestone: THE FAT BOY

ISRO has been scaling the biggest of the mountains ever since its inception. The organisation has made every citizen of India proud by establishing the name of the country in the global world. ISRO has achieved major milestones throughout its journey and has made everyone proud.

Adding another feather to its master hat, ISRO recently launched a new satellite by the name of the “ THE FAT BOY “ also known as geosynchronous satellite launch vehicle mark III-D1 on June 5. 17:28. It is India's heaviest but also the smallest rocket which went to be ISRO’s next step to establish man’s footprints in space after the groundbreaking success of Mars Orbiter Mission. The rocket was 43 metres high and 4 meters wide. The reason it was named the fat boy was to be because of its humongous capability to carry a load of 640 tonnes, which is almost equal to 200 elephants!. It is a three-stage vehicle with world’s heaviest two solid motor strap-on boosters, a liquid propellant core stage and a Cryogenic Upper Stage (CUS). The new Cryogenic engine uses liquid oxygen and liquid hydrogen as its propellants. It is equipped with next generation advanced spacecraft technologies including indigenous Lithium (Li) ion battery and bus subsystem. This rocket is much more manoeuvrable than other rockets launched in this feature hence making it a marvellous invention till date.

Its development began in early 2000’s while the first launch date was decided to be for 2009-10. Several adversities came through due to 2010 failure of GSLV MK-II. With a passive cryogenic third stage, ISRO finally got its much-needed success. It took ISRO scientists 15 years to master the cryogenic technology. Apart from India, only three countries have previously mastered it- U.S, Russia and China. It is better than its previous editions due to possessing four-tonne class satellites into geosynchronous transfer orbits. Thus the launch will increase India’s capability to carry payloads from the current gap of two tonnes. It is a next generation rocket which is also the heaviest making ISRO self-reliant in launching heavier communication satellites of INSAT-4 class.

Importance Of Olympiads For Students

“Practice makes a man perfect”

If not perfect then atleast puts you on your way to perfection.

Since early ages, men has always worked hard to stride forward. Being at the top of ecological cycles, men has always wanted to dominate things. Competition not only prepares you for a certain test but also adds value to your overall perspective. A normal level test may fetch you some marks but a national level competition or Olympiad gives you experience and provides you with utter confidence which makes you a different person altogether. A student should always look for new opportunities and should work hard to achieve their dreams. Hence participating in Olympiads and national level competition is recommended because:
 1. The exposure the new learning: by competing in such exams, students gain additional knowledge. They learn nee ways to answer the questions in new smart and short way. The exam pressure makes students sharp minded hence allowing them to tackle questions with undisputed skills.
2. Understanding of concepts and their application: participation in such exams makes students mind broad and more receptive towards new ideas. Students not only learn new concepts but also learn how to apply them
3. Self-analysis: through such exams, students get to analyse themselves at the local, national and international level and hence allowing them to excel.
4.  Awards and Recognition: Awards boost student’s morale. Winning boosts up the confidence of students.
5.  Moral and psychological benefits: such exams put the student's skills to the test. They allow you to go on after a loss and work even harder after a win. Hence making a student’s personality neutral.

Winning in such exams is not guaranteed but very few institutes provide you skill development with new knowledge.  Eduheal Foundation is the best institute in Delhi for space science olympiad and national space science Olympiad coaching. The institute with its fine blend of experience and skills equip the students with all that is required to excel. The premier space science Olympiad coaching institute in Delhi provides you with experienced faculty to help you overcome study related issues hence becoming an overall best package for the aspirants.

The Man Who Saw India From Space

The infinite space has bewildered humans from long gone centuries. Everyone has at one point of time in their whole life of going to space for once or just place your feet on the surface of the moon. For many, this may just a dream or a figment of their imagination. But some people work hard and do every bit to put their dream on the mechanism of reality. Rakesh Sharma is a name not unknown to any citizen of India because he is the first Indian citizen to travel into space.
Rakesh Sharma was Born on 13 January 1949 in Punjab. Having an acute interest in the army, he joined Air Force as a cadet in 1966 at the age of 18. Proving his mettle and through his extreme hard work and dedication, he was commissioned into the Indian Air Force in 1970 to become a pilot. In 1984 he became the first Indian citizen to enter into space when he flew aboard the Soviet rocket Soyuz T-11. Rakesh Sharma spent 7 days 21 hours and 40 minutes aboard while conducting various experimental sessions. Upon his arrival, he was conferred with the honour of “Hero of the Soviet Union”. He was also conferred with “Ashok Chakra” by the Indian government.

Tarannah-e-hind or saare jahan se achcha hindustan humara was penned by the talented poet Muhammed Iqbal in 1904. The poem which guarantees goosebumps is warmly accepted by everyone. The lyrics of the song were earlier just mere words but these words were externalised by the words of Rakesh Sharma. When the former prime minister of India late. Indira Gandhi asked Sharma through an official television news conference that how does India look from space, Rakesh Sharma proudly answered “ Saare jahan se achchha hindustan humara”. He mainly worked in the field of biomedicine and remote sensing.

Sharma’s sheer hard work and dedication made him what he is today. The reputation respect and appreciation which he garnered was a result of his determination and focus. Rakesh Sharma truly made every Indian proud by achieving such feat. Due to this his name is externalised and will be remembered by every generation with loads of respect. Hats off sir.
