New space telescope will explore violent Universe

European astronomers will be able to explore the universe with a powerful new Japanese space telescope thanks to an agreement recently signed.


Officials from the European Space Agency (ESA) and the Japanese Aerospace Exploration Agency (JAXA) will cooperate in building and operating a satellite called Astro-H.
The orbiting observatory will watch the heavens with X-ray eyes, the latest in a number of space telescopes that can view this part of the spectrum beyond that of visible light. X-rays are emitted by extremely hot events at temperatures ranging from several million to several hundred million degrees Celsius.
Watching them will allow space scientists to observe some of the most extreme phenomena in the Universe including supernova explosions, neutron stars, black holes and the centres of active galaxies.
It will also help them to probe the large-scale structure of the Universe, including clusters of galaxies, and discover how it has evolved over billions of years. It will also help show how matter behaves in extreme gravitational fields.
The deal to work together on this exciting mission was signed last month by Professor Alvaro Giménez Cañete, ESA Director of Science and Robotic Exploration, and Dr Junjiro Onoda, Director General of the Japanese Institute of Space and Astronautical Science (ISAS).

In the quest to understand how the world's weather moves around the globe, scientists have had to tease apart different kinds of atmospheric movement, such as the great jet streams that can move across a whole hemisphere versus more intricate, localized flows. Much the same must currently be done to understand the various motions at work in the great space weather system that links the sun and Earth as the sun shoots material out in all directions, creating its own version of a particle sea to fill up the solar system.

"People think of the sun as giving out light and heat," says Ruth Skoug, a space scientist at Los Alamos National Laboratory in Los Alamos, N.M. "But it is also always losing particles, losing mass."

For example, the sun sends out a steady outflow of solar particles called the solar wind and additionally giant, sudden explosions of material called coronal mass ejections or CMEs erupt out into space. Skoug studies a third kind of particle flow: jets of high-energy electrons streaming from the sun known as electron strahl. Through a new five-year study of observations of the strahl, Skoug and her colleagues have researched another piece of this giant space weather puzzle around Earth.

Spacewalk Preps and Robotics for Station Crew

The Expedition 32 crew members living and working aboard the International Space Station Thursday continued preparations for an upcoming spacewalk and worked with the orbiting laboratory’s non-human resident.

Flight Engineer Suni Williams performed maintenance on U.S spacesuit batteries and prepared equipment that will be used on her upcoming spacewalk set for Aug. 30.

During the 6.5-hour excursion, Williams and Flight Engineer Aki Hoshide are slated to replace a faulty power relay unit on the station’s truss, route power cables for the Russian multipurpose module replacing Pirs and replace a failing camera on the Canadarm2 robotic arm.

41 New Transiting Planets in Kepler Field of View

Two newly submitted studies verify 41 new transiting planets in 20 star systems                                                          Two newly submitted studies verify 41 new transiting planets in 20 star systems. These results may increase the number of Kepler’s confirmed planets by more than 50 percent: to 116 planets hosted in 67 systems, over half of which contain more than one planet. The papers are currently under scientific peer-review.

Nineteen of the newly validated planetary systems have two closely spaced transiting planets and one system has three. Five of the systems are common to both of these independent studies.

Is there another planet in the universe?

The astronomers spent years making sure the signals they detected really were from planets.

A second planet in the same system, Kepler-20e, is only slightly bigger  than Earth and even hotter.

Both worlds circle their parent star closely with 'years' that last just nine and sixteen days respectively.

Dr Francois Fressin, one of the astronomers from the Harvard-Smithsonian Centre for Astrophysics in Cambridge, US, said: ‘It is the first time humanity has been able to discover an object similar to the Earth around a star, so maybe we will be able to find others.

‘This could be an important milestone. I think 10 years or maybe even 100 years from now people will look back and ask when was the first Earth-sized planet found. It is very exciting.

Mission STS-52 and Mission STS-42

Dr. Roberta Bondar became Canada's second astronaut in space when she participated in the first International Microgravity Laboratory (IML-I) mission on board Space Shuttle Discovery.

Space Shuttle Columbia made its thirteenth flight when it lifted off, in October 1992, on Mission STS-52. The payloads included the Italian Laser Geodynamic Satellite (LAGEOS) which was used to monitor continental drift, the Attitude Sensor Package (ASP). The United States Microgravity Payload (USMP) consisting of 3 experiments, and CANadian EXperiments (CANEX-2), consisting of seven experiment.

Chris Hadfield - Astronaut Mission

In December 2012, Canadian astronaut Chris Hadfield will launch aboard a Soyuz spacecraft to reach the International Space Station (ISS).

Length of the mission: 6 months

Objectives:

• Carry out scientific experiments
• Operate Canadarm2 and perform robotics tasks
• Oversee operations as 1st Canadian Commander of theISS as of March 2013

Mission STS-41-G

Marc Garneau conducted 10 experiments in three main categories: space technology, space science and life sciences. The space technology experiments involve two areas: important development tests for the NRCC Space Vision System experiment to be flown on a mission in early 1986 and tests to determine the effect of exposure to space on different advanced composite materials.

The space science studies deal with the physical characteristics of the space environment and of the earth's upper atmosphere. The life sciences component includes several experiments on human adaptation to space flight as preparation for the more detailed investigations on a mission in mid-1986.

Final Flight of the Space Shuttle Atlantis - Mission STS-135

Mission STS-135 marked a turning point in space history as Shuttle Atlantis performed the last flight of the Space Shuttle Program. Atlantis launched from the Kennedy Space Center with four astronauts on board.

The 13-day mission to the International Space Station delivered the Raffaello multi-purpose logistics module containing supplies, logistics and spare parts. During this mission, Dextre received a payload to demonstrate the potential for refueling spacecraft robotically in flight. The TriDAR technology, the science experiment Hypersole as well as the education project Tomatosphere were also carried aboard the Shuttle.The Canadarm was retired after 30 years of service to the Space Shuttle Program upon completion of STS-135.

Curiosity rover lands on Mars

In an unparalleled technological triumph, a one-ton nuclear-powered rover the size of a small car was lowered to the surface of Mars on the end of a 25-foot-long bridle suspended from the belly of a rocket-powered flying crane late Sunday to kick off an unprecedented $2.5 billion mission.  Read more at Spaceflight Now.

NASA going deeper in mars

NASA has selected a new mission, set to launch in 2016, that will take the first look into the deep interior of Mars to see why the Red Planet evolved so differently from Earth as one of our solar system's rocky planets.

The new mission, named InSight, will place instruments on the Martian surface to investigate whether the core of Mars is solid or liquid like Earth's, and why Mars' crust is not divided into tectonic plates that drift like Earth's. Detailed knowledge of the interior of Mars in comparison to Earth will help scientists understand better how terrestrial planets form and evolve.

"The exploration of Mars is a top priority for NASA, and the selection of InSight ensures we will continue to unlock the mysteries of the Red Planet and lay the groundwork for a future human mission there," NASA Administrator Charles Bolden said. "The recent successful landing of the Curiosity rover has galvanized public interest in space exploration and today's announcement makes clear there are more exciting Mars missions to come."(Credit to NASA)

What is the Biggest Planet in the Solar System?

The biggest  plant in the solar system is jupiter.It is the largest by mass, volume, and surface area among other statistics.The diameter at the equator of Jupiter is 140,000 kilometers. All of the planets in our solar system could nicely fit inside Jupiter twice over!

Jupiter is classified as a Gas Giant planet, meaning that it is mainly composed of gases; hydrogen with a little helium mixed in and trace amounts of other elements.


It does have a solid core, made of different materials and thought to be roughly 12 times or more the mass of the Earth.Jupiter has 63 known moons, but four are large enough to be of note; Io, Europa, Ganymede and Callisto. The Galileo spacecraft, the only space mission dedicated to Jupiter, orbited the planet for 7 years enabling us to glimpse up close and personal the Shoemaker-Levy comet’s collision with the planet and to gain some spectacular photographs of its larger moons.(Credit to NASA)

What is a solar flare ?

NASA’s Solar Dynamics Observatory (SDO) captured this image of an M-class flare on August 17, 2012, at 9:01 PM EDT. The flare, seen on the left (or east) side of the sun from an active region that has not yet been named, and is just rotating into view. The image is colorized in teal, which is typical for showing light in the 131 Angstrom wavelength -- a wavelength particularly good for viewing solar flares.
A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the sun and they can last from minutes to hours. We typically see a solar flare by the photons (or light) it releases, at most every wavelength of the spectrum. The primary ways we monitor flares are in x-rays and optical light. Flares are also sites where particles (electrons, protons, and heavier particles) are accelerated.(Credit to NASA)
