The India GSLV launch has been delayed after a fuel leak
Dear followers,
yesterday India planed to launch GSLV rocket with the payload GSAT-14 from the Satish Dhawan Space Center at Sriharikota Island on India's east coast. However, it seems that a fuel leak before the countdown stop the launch process. This launch should be the first one since back-to-back failures in 2010.

The Geosynchronous Satellite Launch Vehicule (GSLV) is and expendable launch system operated by the India Space Reasearch Organisation (ISRO). This launcher has been developed to enable India to launch its own INSAT-type satellites into GEO orbit and to make India less dependent on foreign rockets such as Ariane5 or the Soyuz program.

NASA does not intend to repair Kepler
Dear followers,
many month ago, we talk you that some technical troubles happened on the Kepler spacecraft. Today, +NASA announced that they do not plan to repair the spacecraft.

Actually, +Kepler Space Telescope is blocked by the malfunction of a mechanism which allows the telescope to focus on a given point in the sky towards.
An engineering study will be done on the modifications required to manage science operations with the spacecraft using a combination of its remaining two good reaction wheels and thrusters for spacecraft attitude control.Depending on the outcome of these studies, which are expected to be completed by the end of this year, +NASA will assess the scientific priority of a two-wheel Kepler mission.
Discovery of huge cloud of gas by NASA
Dear followers,
+NASA has discovered using the Chandra X-ray observatory a huge could of multimillion-degree gas in a far away galaxy. The phenomenon is likely caused by a collision between a dwarf galaxy and a spiral galaxy. This impact must caused shock wave that generated hot gas with a temperature of about six million degrees.

The gas cloud is located in a galaxy about 60 million light years from Earth. This discovery could explain how galaxy grow through similar collisions. The mass of the entire gas could could is uncertain because it can not be determined from the 2D image, from the Chrandra X-ray.

A pink exoplanet found
Dear followers,
an international team of astronomers has found a giant planet around the start GJ 504. The new exoplanet, called GJ 504b, has been discovered thanks to infrared data from the Subaru Telescope in Hawaii. This giant planet is the lowest-mass planet (several times the mass of Jupiter) detected around a start like the sun using direct imaging techniques.
The distance between GJ 504b and its sun is nine times the distance Jupiter-Sun. This point poses a challenge to theoretical ideas of how giant planets form.
The astronomer team estimates the system of the Sun GJ504 located in the constellation Virgo is about 160 million years old. This estimated has been based on methods that link the start's color and rotation period to its age.
The race to find exoplanets is still growing all around the world, and astronomers works hard to find a possible planet with life conditions.

Successful NASA's launch of suborbital rocket dedicated for student experiments
Dear followers,
yesterday morning, a suborbital rocket, carrying experiments developed by university students from all USA, was successfully launched at 6:00 am from +NASA's launch range at the Wallops Flight Facility in Virginia.

The Rocksat-X program is conducted with the Colorado Space Grant Consortium. The goal of the program is to provide a hand-s on experience in developing experimental setup dedicated for space flight. This great experience leads the students to participate to a real life space project.
The rocket launched yesterday reached the approximated altitude of 94 miles above the Atlantic ocean before landing using parachute close to the Wallops Flight Facility. The recovery of the payload is still in process.
The students will get back their experimental equipment later to see how they performed and begin data analysis. Moreover, they will use data sent by other experiments during the flight via the telemetry system on board the rocket.

The next NASA's spacecraft to Mars arrived at Kennedy Space Center
Dear follower,
After Curiosity, the rover sent to the red planet by +NASA to explore the land of Mars, the American space agency, works on a new spacecraft : MAVEN. This spacecraft should be sent before the end of this year.
The new Mars spacecraft called MAVEN for Mars Atmosphere and Volatile Evolution arrived on August 3rd at the +NASA agency at Kennedy Space Center in Florida. MAVEN was flown to Florida for launch processing from Buckley Air Force base near the +Lockheed Martin facility in Littleton, Colorado, where the spacecraft was built.
The next Mars mission should lift off on a United Launch Alliance Atlas V rocket in November 2013. The travel of the spacecraft should be around 10 month. This mission will be the first one dedicated to studying Mars' upper atmosphere and the scientists of +NASA and +NASA Jet Propulsion Laboratory hope to find traces of the ancient environment of the red planet.

No Star Treck names for the Pluto's moons
Dear followers,
the two last moons discovered in orbit around Pluto in 2011 and 2012 by the +Hubble Space Telescope, has firstly called by numerical identifiers, respectively P4 and P5. Actually, in astronomy, naming of planets go to the finders and in this case, that honor went to a scientific team led by +Mark Showalter a researcher at the +SETI Institute in Mountain View, California.

After a online vote, many fans of +Star Trek proposed the name of Vulcan, the name of Spock's home planet. However, the International Astronomical Union (IAU) rejected this proposition. Actually, Vulcan was the name given to a hypothetical planet astronomers thought they had discovered between the Sun and Mercury back in the 1800s.
Finally, the two Pluto's moons will be called Kerosene and Styx, two names of the roman and greck mythology.
