What Happens When the Winds of Giant Stars Collide?

From an ESA press release:

Two massive stars racing in orbit around each other have had their colliding stellar winds X-rayed for the first time, thanks to the combined efforts of ESA’s XMM-Newton and NASA’s Swift space telescopes. Stellar winds, pushed away from a massive star’s surface by its intense light, can have a profound influence on their environment. In some locations, they may trigger the collapse of surrounding clouds of gas and dust to form new stars. In others, they may blast the clouds away before they have the chance to get started.

Now, XMM-Newton and Swift have found a ‘Rosetta stone’ for such winds in a binary system known as Cyg OB2 #9, located in the Cygnus star-forming region, where the winds from two massive stars orbiting around each other collide at high speeds.

Cyg OB2 #9 remained a puzzle for many years. Its peculiar radio emission could only be explained if the object was not a single star but two, a hypothesis that was confirmed in 2008. At the time of the discovery, however, there was no direct evidence for the winds from the two stars colliding, even though the X-ray signature of such a phenomenon was expected.

This signature could only be found by tracking the stars as they neared the closest point on their 2.4-year orbit around each other, an opportunity that presented itself between June and July 2011.

As the space telescopes looked on, the fierce stellar winds slammed together at speeds of several million kilometres per hour, generating hot plasma at a million degrees which then shone brightly in X-rays.

The telescopes recorded a four-fold increase in energy compared with the normal X-ray emission seen when the stars were further apart on their elliptical orbit.

“This is the first time that we have found clear evidence for colliding winds in this system,” says Yael Nazé of the Université de Liège, Belgium, and lead author of the paper describing the results reported in Astronomy & Astrophysics.

“We only have a few other examples of winds in binary systems crashing together, but this one example can really be considered an archetype for this phenomenon.”

Unlike the handful of other colliding wind systems, the style of the collision in Cyg OB2 #9 remains the same throughout the stars’ orbit, despite the increase in intensity as the two winds meet.

“In other examples the collision is turbulent; the winds of one star might crash onto the other when they are at their closest, causing a sudden drop in X-ray emission,” says Dr Nazé.

“But in the Cyg OB2 #9 system there is no such observation, so we can consider it the first ‘simple’ example that has been discovered – that really is the key to developing better models to help understand the characteristics of these powerful stellar winds. ”

“This particular binary system represents an important stepping stone in our understanding of stellar wind collisions and their associated emissions, and could only be achieved by tracking the two stars orbiting around each other with X-ray telescopes,” adds ESA’s XMM-Newton project scientist Norbert Schartel.

MESSENGER Marks 8th Anniversary of Launch

by sandeep janjirala on 09 sept, 2012

The MESSENGER spacecraft launched eight years ago today — on August 3, 2004 — embarking on a six-and-a-half year journey to become the first spacecraft to orbit Mercury. The spacecraft's 4.9-billion mile (7.9-billion kilometer) cruise to history included 15 trips around the Sun, a flyby of Earth, two flybys of Venus, and three flybys of Mercury. 

The mission began capturing ground-breaking science and images from outer space almost immediately. During its gravity assist swing-by of Earth, on August 2, 2005, MESSENGER's cameras captured several hundred images of our planet. These images were sequenced into a movie documenting the view from MESSENGER as it departed Earth toward the inner Solar System.

On October 24, 2006, the spacecraft soared above the cloud deck of Venus for the first time, then returned less than a year later on June 5, 2007, marking the first time in flight that all seven instruments were turned on and operating collectively in science-observing mode. MESSENGER turned its wide-angle camera back to the planet and acquired a departure sequence that provided a spectacular good-bye to the cloud-shrouded planet while also acquiring valuable calibration data for the camera team.

MESSENGER made history on January 14, 2008, when it flew over a portion of Mercury that had never before been seen at close range. In this first of three flybys of the planet, the probe's cameras took 1,213 images and other sophisticated instruments made the first spacecraft measurements of the planet and its environment since Mariner 10's third and final flyby on March 16, 1975.

The mission's penultimate accomplishment — entering orbit about Mercury — was celebrated on March 17, 2011, by a crowd of hundreds gathered at the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The event was covered live, and the webcast is still available online at http://messenger.jhuapl.edu/mer_orbit.html. 

On March 17, 2012, MESSENGER successfully completed a year-long campaign to perform the first global reconnaissance of the geochemistry, geophysics, geologic history, atmosphere, magnetosphere, and plasma environment of the solar system's innermost planet. The following day, March 18, 2012, marked the official start of an extended mission phase designed to build upon those discoveries. This animationshows a sunward view of MESSENGER above Mercury's north polar region during the two orbit-correction maneuvers on April 16 and April 20, 2012, which shortened the orbit period from 12 to 8 hours, allowing MESSENGER an even closer look at the planet.

Less than five months into the extended mission, the team has already made substantial progress on its new objectives. Next week, the team will gather for its 27th Science Team Meeting in Salem, Massachusetts, to discuss the new findings and firm up plans for a second extended mission.

"Our small spacecraft has been a hardy traveler," says MESSENGER Principal Investigator Sean Solomon, of the Lamont-Doherty Earth Observatory at Columbia University. "Across billions of miles, during more than 1,000 orbits about the planet with the greatest extremes in surface temperature, and in the face of streams of energetic particles from an increasingly active Sun, MESSENGER has continued to surpass expectations. Mercury, too, has continued to surprise the scientific community, and the MESSENGER team looks forward to learning more about one of the nearest yet least studied worlds."

Large water reservoirs at the dawn of stellar birth

by sandeep janjirala on 09 sept, 2012

Herschel’s infrared view of part of the Taurus Molecular Cloud, within which the bright, cold pre-stellar cloud L1544 can be seen at the lower left. It is surrounded by many other clouds of gas and dust of varying density. The Taurus Molecular Cloud is about 450 light-years from Earth and is the nearest large region of star formation. The image covers a field of view of approximately 1 x 2 arcminutes.

Close-up of L1544 with the water spectrum seen by Herschel, taken from the centre of the pre-stellar core. The peak of the graph shows an excess in brightness, or emission, while the trough shows a deficit, or absorption. These characteristics are used to indicate the density and motions of the water molecules within the cloud. Emission arises from molecules that are approaching the centre where the new star will form, from the back of the cloud from Herschel’s viewpoint. The amount of emission indicates that these molecules are moving within the densest part of the core, which spans about 1000 Astronomical Units. The absorption signature is due to water molecules in front of the cloud flowing away from the observer towards the centre. These water molecules are in less dense regions much further away from the centre. Together, the emission and absorption signatures indicate that the cloud is undergoing gravitational contraction, that is, it is collapsing to form a new star. Herschel detected enough water vapour in L1544 to fill Earth’s oceans more than 2000 times over.

UK contributes 24 robotic arms in giant leap forward in near-infrared astronomy

by sandeep janjirala on 09 sept, 2012

A new high-tech instrument with 24 robotic arms has crossed the Atlantic from Edinburgh to a mountain top in Chile to address in more detail than ever before, some of the key questions surrounding the beginnings of the Universe, stars and galaxies. KMOS (K-Band Multi Object Spectrometer) has been provisionally accepted by the European Southern Observatory (ESO) after it completed final assembly and testing at the UK Astronomy Technology Centre (UK ATC) in Edinburgh. It will now be fitted to one of the four telescopes which make up the European Southern Observatory’s Very Large Telescope (ESO-VLT) at Paranal in Chile, providing astronomers with a far quicker solution to uncover details about galaxies and their properties.

What makes KMOS unique is its ability to image many galaxies simultaneously either in a cluster or in isolation but in both cases, still see the individual properties of each single galaxy. Until now, each galaxy has had to be identified individually to obtain that information, a process that takes years. KMOS will be able to see the same amount of detail in just two months. 

Each of the 24 cryogenic robotic arms, which have gold plated mirrors on their tips, can be moved into position to pinpoint with extreme accuracy the light coming from distant galaxies. 

Dr Michele Cirasuolo is the lead instrument scientist for KMOS at UK ATC. He said: “KMOS represents a pivotal step in our quest to scrutinise the distant Universe. The ability to observe in the near-infrared 24 galaxies simultaneously is an enormous leap forward compared to any other current instrument.  KMOS will allow a much faster survey speed…most of the observations done by similar near-infrared spectrographs over the last 10 years could be done in just two months with KMOS.”

This novel capability means astronomers will be able to make a detailed study of the mass assembly and star formation in distant, high red-shift galaxies addressing fundamental questions about when these first formed and how they evolve. This ability to observe multiple galaxies at once enables scientists to build up large statistical samples of galaxies at different cosmic epochs necessary to unveil the physical mechanisms that shape their formation and evolution.

KMOS creates this detailed picture using integral field spectroscopy and obtains spectra over a two-dimensional area, covering the entire galaxy. The light from each segment of galaxy (its core, the bulge, the spiral arms and the outer parts) is analysed simultaneously and each can be given physical and chemical properties. Not only therefore, can a complete galaxy be measured, but each individual part too, allowing a comprehensive picture to be built.

“For each of the galaxies, KMOS will give an incredible amount of information. It’s not just a picture of a galaxy, but 3D spectroscopy providing the spatially resolved physics and the chemistry and the dynamics. This is crucial to understand how galaxies assemble their mass and shape their structure as a function of cosmic time, up to the formation of the very first galaxies, more than 13 billion years ago” explains Michele Cirasuolo.  

The specialised mechanisms inside KMOS have been designed to work in cryogenic conditions below minus two hundred degrees centigrade, which has been a major challenge, but which is necessary to observe distant galaxies at near-infrared wavelengths. This is because, unless cooled, the thermal emission from the instrument itself will swamp the faint signal from the astronomical sources.  

Minister for Universities and Science David Willetts said: "It’s excellent to see the UK playing a leading role in the development of such a sophisticated piece of technology and overcoming some very complex engineering challenges on the way. This instrument will now take its place on a world leading telescope to help improve our knowledge and understanding of the universe around us."

The instrument is a collaboration of six institutions in Germany and the UK, including STFC’s UK Astronomy Technology Centre (UK ATC), Durham University, Oxford University and RAL Space at STFC’s Rutherford Appleton Laboratory. The team of internationally respected scientists and engineers at UK ATC played a major role in the KMOS project, being responsible, amongst others, for the construction of the cryostat, the 24 robotic pick-off arms, the cable co-rotator and the final assembly and test of the complete instrument. RAL Space applied their cryogenic lens mounting technology in the three camera barrels they provided for spectrographs in KMOS. Durham University has the PI of the entire project and produced the complex system of more than 1000 mirrors in the integral field unit. Oxford University provided the design and assembly of the three spectrographs in KMOS.

Each incredibly powerful unit telescope on the VLT contains a mirror eight metres in diameter. It is onto the VLT Unit 1 telescope, Antu that the new KMOS equipment will be fitted

SSTL assists Rapid Eye ground station upgrade

by sandeep janjirala on 09 sept, 2012

Surrey Satellite Technology Ltd (SSTL) is undertaking a project to assist geospatial information provider RapidEye AG in upgrading and consolidating its ground station facilities.

Engineers from SSTL’s Ground Systems Group are providing a new and upgraded Spacecraft Control Centre for RapidEye’s headquarters in Brandenburg, Germany and relocating its Tracking, Telemetry and Command (TT&C) ground station equipment to the Kongsberg Satellite Services AS (KSAT) facility in Svalbard, Norway, which receives Earth Observation data from its constellation of five satellites. 

As part of the project, SSTL’s Ground Systems Group will also provide new ground station equipment, to incorporate tracking, telemetry and command and S-band data recovery to the existing X-Band SG-9 antenna system currently used at the KSAT facilities in Svalbard.

The current Spacecraft Control Centre in Brandenburg, Germany, was built by SSTL in 2006 as part of the 5-spacecraft RapidEye constellation mission. The improved Centre will allow RapidEye to continue command and control of their constellation remotely from Germany, while retaining back-up TT&C services through the ground station facilities at SSTL in Guildford, UK.

Galileo satellites moved to pad for Friday launch

by sandeep janjirala on 09 sept, 2012

Galileo IOV satellites attached to their launch dispenser and encapsulated beneath the fairing of their Soyuz ST-B launcher

Soyuz VS03, the third Soyuz flight from Europe’s Spaceport in French Guiana, was transferred to the launch zone on 8 October 2012. The vehicle was rolled out horizontally on its erector from the preparation building to the launch zone and then raised into the vertical position. Soyuz VS03 will lift off on 12 October 2012. The rocket will carry two satellites of Europe’s Galileo navigation system into orbit.

The two Galileo In-Orbit Validation satellites are protected during their launch by Soyuz by a launch fairing. Once the Soyuz has passed most of the way through the atmosphere, this fairing can then be ejected

Falcon 9 Experienced Engine Anomaly But Kept Going to Orbit

by sandeep janjirala on OCTOBER 8, 2012

During last night’s launch of the Dragon capsule by SpaceX’s Falcon 9 rocket, there was an anomaly on one of the rocket’s nine engines and it was shut down. But Dragon still made it to orbit – just a little bit later than originally expected. At about 1:20 into the flight, there was a bright flash and a shower of debris. SpaceX’s CEO Elon Muskissued a statement about the anomaly saying:

“Falcon 9 detected an anomaly on one of the nine engines and shut it down. As designed, the flight computer then recomputed a new ascent profile in realtime to reach the target orbit, which is why the burn times were a bit longer. Like Saturn V, which experienced engine loss on two flights, the Falcon 9 is designed to handle an engine flameout and still complete its mission. I believe F9 is the only rocket flying today that, like a modern airliner, is capable of completing a flight successfully even after losing an engine. There was no effect on Dragon or the Space Station resupply mission.”

SpaceX has successfully launched the first official Cargo Resupply Services (CRS) mission to the International Space Station. The commercial company’s Falcon 9 rumbled rocket to life at 8:35 EDT on Oct 7 (00:35 UTC Oct. 8) in a picture perfect launch, sending the Dragon capsule on its way in the first of a dozen operational missions to deliver supplies to the orbiting laboratory. The launch took place at Launch Complex 40 at Cape Canaveral Air Force Station in Florida, just a few miles south of the space shuttle launch pads.

“This was a critical event for NASA and the nation tonight,” said NASA Administrator Charlie Bolden after the launch. “We are once again launching spacecraft from American soil with supplies that the ISS astronauts need.”

Watch the launch video below:

All the major milestones of the launch ticked off in perfect timing and execution, and the Dragon capsule is now in orbit with its solar arrays deployed. The Dragon capsule separated from the Falcon 9 about 10 minutes and 24 seconds after liftoff. Dragon should arrive at the ISS on Oct. 10 and the crew will begin berthing operations after everything checks out.

All three members of the current ISS crew were able to watch the launch live via a NASA uplink to the ISS, and Commander Suni Williams passed on her congratulations to the SpaceX team, saying “We are ready to grab Dragon!”

Williams and astronaut Akihiko Hoshide will use the CanadArm 2 to grapple the Dragon capsule around 7:22 a.m. EDT (11:22 UTC) Wednesday, moving it to a berthing at the Earth-facing port of the forward Harmony module.

Even though SpaceX sent the Dragon to the ISS in May, that was considered a demonstration flight and this flight is considered the first operational mission.

“No question, we are very excited,” said SpaceX President Gwynne Shotwell just before the launch. “Everyone was very excited in May and we are very much looking forward to moving forward with the operational missions.”

Dragon is carrying approximately 450 kg (1,000 pounds) of supplies, including food, water, scientific experiments and Space Station parts. There are also 23 student experiments from the Student Spaceflight Experiments Program (SSEP) involving 7,420 pre-college students engaged in formal microgravity experiment design, according to SSEP director Dr. Jeff Goldstein.

SpaceX and NASA revealed this weekend a special treat is on board a new freezer called GLACIER (General Laboratory Active Cryogenic ISS Experiment Refrigerator): Blue Bell ice cream, a brand that is a favorite of astronauts training at the Johnson Space Center in Houston. The freezer will be used to return frozen science experiments to Earth.

In the next three days, Dragon will perform systems checks, and start a series of Draco thruster firings to reach the International Space Station.

Dragon will return a total of 750 kg (1,673 pounds) of supplies and hardware to the ground. NASA says Dragon’s capability to return cargo from the station “is critical for supporting scientific research in the orbiting laboratory’s unique microgravity environment, which enables important benefits for humanity and vastly increases understanding of how humans can safely work, live and thrive in space for long periods. The ability to return frozen samples is a first for this flight and will be tremendously beneficial to the station’s research community. Not since the space shuttle have NASA and its international partners been able to return considerable amounts of research and samples for analysis.”

Dragon is currently scheduled to return to Earth at the end of the month, splashing down in the Pacific Ocean on October 29.

Minute Physics: Real World Telekinesis

by sandeep janjirala on OCTOBER 7, 2012

How do magnets affect things at a distance? How does the Sun heat our planet from 93 million miles away? How can we send messages across the world with our cell phones? We take these seemingly simple things for granted, but in fact there was a time not too long ago when the processes behind them were poorly understood, if at all… and, to the uninformed, there could seem to be a certain sense of “magic” about them.

This video from MinutePhysics, featuring director of the Perimeter Institute for Theoretical Physics Neil Turok, illustrates how our understanding of electromagnetic fields was developed and why there’s nothing magic about it… except, perhaps, how they pack all that excellent info into 5 minutes.

How to Steal a Space Shuttle

by sandeep janjirala on OCTOBER 6, 2012

For two days, from October 12 to 13, the shuttle Endeavour will be transported along 12 miles of road on the final leg of its journey to the California Science Center. During that time the orbiter will be the most publicly exposed as it’s ever been, a national treasure on the streets of LA. While this will of course be a well-orchestrated undertaking with the security of not only Endeavour but citizens and spectators being of utmost priority, one might be prompted to speculate: what if someone tried to steal the space shuttle?

And that one, in this instance, was Jalopnik.com‘s Jason Torchinsky. In his latest article, Jason describes in detail a method for snatching a spaceship — and a rather dramatic one at that, worthy of a Bondian supervillian (and requiring a similarly cinematic amount of funds.) However nefarious, fictitious, and unlikely, it’s nevertheless intriguing.

Surreal Photos: CubeSats Launched from the Space Station

by sandeep janjirala on OCTOBER 6, 2012

Five tiny CubeSats were deployed from the International Space Station on Thursday and astronaut Chris Hadfield called the image above “surreal” on Twitter. And rightly so, as they look like a cross between Star Wars training droids and mini Borg Cubes from Star Trek. The Cubesats measure about 10 centimeters (4 inches) on a side and each will conduct a range of scientific missions, ranging from Earth observation and photography to technology demonstrations to sending LED pulses in Morse Code (which should be visible from Earth) to test out a potential type of optical communication system.

These are low-cost satellites that could be the wave of the future to enable students and smaller companies to send equipment into space. If you’re worried about these tiny sats creating more space junk, Hadfield assured that since they are very light and in such a low orbit, the Cubesat orbits will decay within a few months.

The Rubic-cube-sized Cubesats were deployed from the new Japanese Small Satellite Orbital Deployer that was brought to the space station in July by the Japanese HTV cargo carrier.

The Japanese FITSAT-1 will investigate the potential for new kinds of optical communication by transmitting text information to the ground via pulses of light set to Morse code. The message was originally intended to be seen just in Japan, but people around the world have asked for the satellite to communicate when it overflies them, said Takushi Tanaka, professor at The Fukuoka Institute of Technology.

Observers, ideally with binoculars, will be able to see flashes of light — green in the northern hemisphere, where people will see the “front” of the satellite, and red in the southern hemisphere, where the “back” will be visible.

The message it will send is “Hi this is Niwaka Japan.” Niwaka is the satellite’s nickname and reflects a play on words in the local dialect of southwestern Japan, according to an article on Discovery Space. To see the Morse Code message, the Cubesat will be near the ISS, so find out when you can see the ISS from NASA or Heaven’s Above. Find out more about the FITSAT at this website.

The other Cubesats include NASA’s TechEdSat which carries a ham radio transmitter and was developed by a group of student interns from San Jose State University (SJSU) in California with mentoring and support from staff at NASA’s Ames Research Center.

“TechEdSat will evaluate plug-and-play technologies, like avionics designed by commercial providers, and will allow a group of very talented aerospace engineering students from San Jose State University to experience a spaceflight project from formulation through decommission of a small spacecraft,” said Ames Director S. Pete Worden.

The other Cubesats include RAIKO, which will do photography from space, We Wish, an infrared camera for environmental studies, and and the F-1 Vietnam Student CubeSat which has an on-board camera for Earth observation.
