In my travels, I’ve had the pleasure of regularly meeting up with Camilla the Rubber Chicken, the social media maven and mascot for NASA’s Solar Dynamics Observatory. But lately I’ve been seeing here virtually everywhere — on television, splashed across all sorts of websites, and even in my local newspaper. What Camilla does is try to capture the imagination of students and get them interested in space and science. With her latest adventures she’s done just that, and now captured the attention of people all around the world, too.

What did she do? She flew to the stratosphere — about 36,000 meters (120,000 ft) up — on a helium balloon right into the throes of one of the most intense solar radiation storms since 2003.

“I am still glowing,” Camilla joked.

Students from Bishop Union High School’s Earth to Sky group spearheaded the flights, as Camilla actually flew twice — once on March 3 before the radiation storm and again on March 10 while the storm was in full swing. This would give the students a basis for comparison of the radiation environment.

On board with Camilla was a payload of four cameras, a cryogenic thermometer two GPS trackers, radiation detectors, Seven insects and two-dozen sunflower seeds (fittingly, the variety known as “Sunspot” — Helianthus annuus) all inside a modified department store lunchbox.

“We equipped Camilla with sensors to measure the radiation,” says Sam Johnson, 16, of Bishop Union High School’s Earth to Sky student group. “At the apex of our flight, the payload was above 99 percent of Earth’s atmosphere.”

Camilla made it back in one piece, but unfortunately, the insects died.

“This story is really about STEM (science, technology, engineering and math) and about these kids from Bishop, California who have worked really hard in developing the mission, planning it, and then executing it,” Camilla told Universe Today. “They had to overcome set-backs, review their processes, come up with better solutions and implement them. For them it was a great hands-on learning experience and they are and can be proud of their accomplishments.”

NASA knows that these kinds of programs, where kids can get involved in hands-on research, are very important for introducing and keeping students interested in STEM subjects, important areas of study for future NASA scientists and engineers.

“As you know, I not only want to educate about our Sun and space weather, but I want to inspire and show kids (and adults) how much fun science and engineering really is,” Camilla said via email. “Team SDO’s goal has always been to encourage more girls into STEM careers and seeing that this team had several girls on the team was just the most rewarding.”

The video of the balloon popping and part of Camilla’s flight:

During the two-and-a-half-hour flights, Camilla spent approximately 90 minutes in the stratosphere where temperatures ( -40 to -60 C, -40 to -76 F) and air pressures (1 percent sea level) are akin to those on the planet Mars. The balloon popped, as planned, at an altitude of about 40 km (25 miles) and Camilla parachuted safely back to Earth. The entire payload was recovered intact from a landing site in the Inyo Mountains.

The fifth grade students who assisted with the flight have planted the sunflower seeds to see if radiated seeds produce flowers any different from seeds that stayed behind on Earth. They also pinned the corpses of the insects to a black “Foamboard of Death,” a rare collection of bugs that have been to the edge of space.

Meanwhile, Camilla’s radiation badges have been sent to a commercial laboratory for analysis.

The students say they are looking forward to the data and perhaps sending Camilla back for more.

“I truly believe that text books will always be around,” Camilla said, “but real-life hands-on projects like these are wonderful, and will become more popular.”

Here’s a video of an X-class flare from sunspot AR1429, which unleashed more than 50 solar flares during the first two weeks of March:

Fragments of Meteorite Worth Their Weight in Gold

Actually it’s more like 3.5 times their weight in gold, according to today’s market value… and meteorite experts from SETI and NASA’s Marshall Space Flight Center.

During the daylight hours of April 22, 2012, reports came in from all over the north central California area of an extremely bright fireball — described as a “glittering sparkler” — and accompanying loud explosion. It was soon determined that this was the result of a meteoroid about the size of a minivan entering the atmosphere and disintegrating. It was later estimated that the object weighed about 70 metric tons and detonated with a 5-kiloton force.

Read more about the California fireball event here.

Over a thousand meteorite hunters scrambled to the area, searching for any traces of the cosmic visitor’s remains. After a few days, several pieces of the meteorite were found and reported by five individuals, adding up to 46 grams in total.

Those pieces could be worth over $9,000 USD, according to Bill Cooke of NASA’s Meteoroid Environment Office at Marshall Space Flight Center.

Based on today’s market, that’s about 3.6 times the value of gold (about $1,660 per troy ounce — 31.1 grams).

The high value is due to the extreme rarity of the meteorite fragments. The California fireball is now known to have been created by a CM chondrite, a type of carbonaceous meteorite with material characteristics similar to comets.

SETI Institute's Franck Marchis and the chondrite fragments (F. Marchis)

According to Franck Marchis, Planetary Astronomer at the Carl Sagan Center of the SETI Institute and one of the coordinators of the meteorite reporting teams, CM chondrites appear to have been altered by water, and have deuterium-to-hydrogen ratios in line with what’s been measured in the tails of comets Halley and Hyakutake.

They also have been found to contain organic compounds and amino acids, lending to the hypothesis that such meteorites may have helped supply early Earth with the building blocks for life.

But due to their fragile composition, they are also incredibly rare. Only 1% of known meteorites are CM chondrites, making even the small handful of fragments found in California very valuable.

“This will be only the third observed CM fall in the US, after Crescent, OK, in 1936, (78 g) and Murray, KY, in 1950 (13 kg),” Marchis told Universe Today.

As far as what the finders will do with the fragments, that’s entirely up to them.

“They can sell them on eBay or they can lend them to the scientists… or make a donation.” Marchis said.

Just goes to show that all that glitters really isn’t gold — it could be even better.

Read more in an article by Sara Reardon on New Scientist, and read more on the comet/chondrite connection here. And the ongoing search for pieces of what’s now being referred to as the “Sutter’s Mill Meteorite” can be followed here and here.

The largest CM chondrite ever recovered was from a fall in Murchison, Australia on September 28, 1969. The total mass of its collected fragments weighed in at over 100 kg (220 lbs).

Video: NASA’s Pursuit of Light and Big Science

The folks at NASA Goddard’s multimedia division have outdone themselves this time on a new video compilation which, really, shows how NASA dreams big science. Its asks the big questions of why we really explore and how important these explorations can be. It shows views of the Earth, the planets, the Sun, and the endless universe beyond. The video description says it best: “Come for the cool, stay for the music, take away a sense of wonder to share. It’s six minutes from Earth to forever, and you can see it here!”

And what will be lost if NASA is allowed to just fade away through neglect? If you live in the US, contact your Congress members and encourage them to support NASA. Currently NASA’s budget isn’t big enough to even show up as a line on a pie chart, and represents 0.46% of the US budget — less than half a penny for every dollar spent in the US, and has been relatively unchanged for 25 years.

Here’s a graph of what NASA’s percentage of the budget has been like over time:

“NASA contributes to society in massively huge ways in terms of technological, economical, and inspirational progress,” says the website Penny4NASA. “The progress that we have seen in the last 40 years comes largely from the world’s extremely talented scientists and engineers. Now, talk to most any scientist and/or engineer of the last 40 years, and we are willing to bet that they were drawn into their chosen field by something NASA related.”

There’s a new four-part interview series with Apollo astronaut Neil Armstrong, and part 1 is now available for viewing. The first man to walk on the Moon gives a personal commentary on Apollo 11’s historic lunar landing, his thoughts on leadership and taking risks to innovate for the future. With the future of NASA’s program currently under scrutiny, throughout the series Armstrong will talk about his position on the policy direction of the space agency, speaks candidly on his early life, and even tackles conspiracy theorist claims that the Moon landing never happened – using images from Google Moon to demonstrate their path. The series also includes previously unseen footage of the lunar descent. Armstrong doesn’t give many interviews, and the show’s producers say this is the first on-camera interview Armstrong has done since 2005. The episodes are from evoTV’s series, The Bottom Line.

The different parts will be released over the next few weeks:

Part 1 – Space Race: now available

Part 2 – Blast Off available 8 May

Part 3 – Giant Leap available 15 May

Part 4 – Presidential Pride available 22 May

What a Space Shuttle Launch REALLY Sounded Like

When I attended my first space shuttle launch, the most amazing thing about the whole launch experience may have been the sound. Being there at Kennedy Space Center is nothing like seeing it on television. When the sound waves travel across the 5.6 km (3.5 miles) from the launchpad to the KSC press site, the noise and sound just absolutely overwhelm and engulf you. You don’t only hear and see a space shuttle launch, you *feel* it! I heard astronaut Steve Robinson describe it as “it seems the air just isn’t big enough for the sound.” That sums it up pretty well.

Each launch I attended, I tried to record the crackling and popping of the rockets burning, but my audio equipment was just overwhelmed and the sound was completely distorted. This video is fairly close to what the sound is like, especially if you use a good sound system and turn it up, as the video’s creator, indiegun suggests. He used dozens of different video sources and several audio versions of shuttle launches mixed together to mimic as close to the real experience as he could.

NASA’s STEREO Spots a New Nova

STEREO-B image of Sagittarii 2012 (STEREO/SECCHI/NASA/NRL)


While on duty observing the Sun from its position in solar orbit, NASA’s STEREO-B spacecraft captured the sudden appearance of a distant bright object. This flare-up turned out to be a nova — designated Sagittarii 2012 — the violent expulsion of material and radiation from a re-igniting white dwarf star.

Unlike a supernova, which is the cataclysmic collapse and explosion of a massive star whose core has finally fused its last, a nova is the result of material falling onto the surface of a white dwarf that’s part of a binary pair. The material, typically hydrogen and helium gas, is drawn off the white dwarf’s partner which has expanded into a red giant.

Eventually the white dwarf cannot contain all of the material that it has sucked in from its neighbor… material which has been heated to tremendous temperatures on its surface as it got compressed further and further by the white dwarf’s incredibly strong gravity. Fusion occurs on the dwarf’s outermost layers, blasting its surface out into space in an explosion of light and energy.

This is a nova — so called because, when witnessed in the night sky, one could suddenly appear as a “new star” in the heavens — sometimes even outshining all other visible stars!

An individual nova will soon fade, but a white dwarf can produce many such flares over time. It all depends on how rapidly it’s accreting material (and how much there is available.)

Over the course of 4 days, Sagittarii 2012 reached a magnitude of about 8.5… still too dim to be seen with the unaided eye, but STEREO-B was able to detect it with its SECCHI (Sun Earth Connection Coronal and Heliospheric Investigation) instrument, which is sensitive to extreme ultraviolet wavelengths.

The video above was made from images acquired from April 20 – 24, 2012.

It’s not known yet how far away Sagittarii 2012 is but rest assured it poses no threat to Earth. The energy expelled by a nova is nowhere near that of a supernova, and although you wouldn’t want to have a front-row seat to such an event we’re well away from the danger zone.

What this does show is that STEREO-B is not only a super Sun-watching sentinel, but also very good at observing much more distant stars as well!

Thanks to @SungrazerComets for the heads-up on this novel nova!

OMG Space

OMG Space attempts to portray the scale sizes and distances in the Solar System

[/caption]

“You may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.” – Douglas Adams

Standard classroom models and textbook illustrations of the Solar System, regardless of how pretty they are, all share one thing in common: they’re wrong. Ok, maybe not wrong, but definitely inaccurate… especially in regards to scale. And understandably so, as it’s nearly impossible to portray in a convenient manner the sheer amount of space there is between the planets and their relative sizes. Even if a model manages to show one or the other in a straightforward, linear fashion, it usually doesn’t show both.

This one does.

OMG Space is a web page made by Margot Trudell as graphic design thesis project at Toronto’s OCAD University. Displayed on the Visual.ly portfolio site, Margot’s expansive infographic shows the Sun, planets and some minor bodies to scale, both in terms of relative size and distance. By clicking on a planet’s name at the bottom of the page you’ll be whisked away toward it, giving a sense of how very far it really is between the many worlds that make up our own little Solar System.

And if that’s not enough, Margot has included a descriptive chart for each world that gives basic information on distance from the Sun, orbital period and moon count as well as details on visiting exploration missions — past, present and planned. These can be accessed by clicking on the respective worlds once you arrive.

Each planet has an infographic associated with it, showing physical characteristics and exploration timelines. (M. Trudell)

“I created the infographics first and as I worked on them decided they needed more context, and the idea of creating a to scale version of our solar system came to mind,” Margot told Universe Today. “The project was initially intended to be all print, but knowing the real scale of our solar system I eventually came up with the idea of using the infiniteness of the web to my advantage.”

If you watch the scroll bar on the right side of the page (and I do suggest resizing the page to fill your screen as much as possible) you’ll also get a sense of how much space you’re traversing as you zip between worlds. And that’s just taking into consideration the average distances between each planet at opposition. In reality, they’re never lined up in a row like that!

If you’re so inclined you can also scroll up and down manually… if only to see how long it takes you to not get anywhere.

“My favourite thing to do on OMG Space’s website is go to Earth and then click on the link to the Moon,” Margot said. “The small distance you move yet the big gap you see… it gives you a whole new perspective on how far people traveled to get to the moon and back, and it shows how far the moon really is from Earth (I feel that it’s always portrayed as being almost right beside us) and makes you consider how powerful those rockets must have been to get us that far.

“It gives you a bit of that ‘OMG’ feeling that the project is named for.”

Yes, OMG indeed.

View from Orbit of a Huge White Sands Dust Storm

Driven by southwesterly winter winds, dust from the White Sands dune field in New Mexico rises thousands of feet from the valley floor and drifts over the snowy peaks of the Sacramento Mountains. Credit: NASA

[/caption]

It’s clear from this image of why a region in New Mexico, USA is called ‘White Sands.’ The dust plumes in this photograph taken by an astronaut on board the International Space Station show a dust storm in the White Sands National Monument. But this is a huge dust storm. The white dust plumes stretch across more than 120 kilometers (74 miles).

Caused by winds that channel the dust through a low point in the mountains, the vigorous winds are lifting dust particles from the valley floor to more than 1200 meters over the mountains. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite also captured a wider, regional view of the same storm on the same day.

The sand dunes of this national monument are white because they are composed of gypsum, a relatively rare dune-forming mineral. The dunes’ brilliance, especially contrasted against the nearby dark mountain slopes, makes them easily identifiable to orbiting astronauts. The white speck of the dunes was even visible to the Apollo astronaut crews looking back at Earth on the way to the Moon.

SpaceX Static Test Fire a Success

It was short but sweet. SpaceX conducted a 2-second static fire test of their Falcon 9 rocket that will send the first COTS flight to the International Space Station. “Woohoo, rocket hold down firing completed and all looks good!!” Tweeted SpaceX CEO and founder Elon Musk. SpaceX’s Twitter feed said with the successful firing, engineers will now review data as they continue to prepare for the upcoming mission, slated to launch on May 7.

A first attempt was aborted with 30 seconds left in the countdown, due to “overly restrictive redline on second stage engine position.” Engineers recycled all the rocket’s systems and began another countdown.

Fire and smoke erupted just briefly from the base of the rocket, and there seemed to be a bit of confusion on the webcast, as the word “abort” was used, but then there was word of success and the webcast ended abruptly.

[/caption]

For the static fire test, the nine Merlin engines on the first stage of the Falcon 9 rocket were ignited at 20:15 UTC (4:15 p.m. EDT). The test was part of a full dress rehearsal for the SpaceX team. Last week was a final full simulation between NASA and SpaceX for the series of demonstration maneuvers and tests the Dragon capsule will make as it approaches the ISS; then the astronauts on board will capture and berth the cargo capsule to the Harmony module’s Earth-facing docking port.

If the abort problem had occured on the launch day, there would be no second attempt; there is no recycling of the systems for an actual launch. Additionally, the Falcon 9 can only attempt launch every 3 days because of limited propellant on Dragon capsule. SpaceX needs to ensure there is enough propellant on board Dragon for the pre-berthing maneuvers and tests.

If the Falcon 9 launch is delayed by weather or technical problems, another attempt could be made on May 10, but after that they would have to until after the launch of a Russian Soyuz spacecraft that will bring three new crew members to the space station. That mission is scheduled for launch from the Baikonur Cosmodrome in Kazakhstan on May 14, and would dock two days later.

The launch of the Falcon 9 and Dragon has been delayed from its initial planned flight in February, but with today’s apparently successful test, SpaceX and NASA are hopeful for going forward with next week’s launch.

SpaceX is one of two companies, along with Orbital Sciences, competing for contracts to deliver cargo to low Earth orbit for NASA under the Commercial Orbital Transportation System program.

The launch is currently set for 13:38 UTC (9:38 a.m. EDT) on Monday.

Chandra Witnesses Big Blast from an Old Black Hole

Before and After Images in X-ray and Optical Light In Chandra observations that spanned several years, the ULX in M83 increased in X-ray brightness by at least 3,000 times. This sudden brightening is one of the largest changes in X-rays ever seen for this type of object, which do not usually show dormant periods. (Credit: Optical: ESO/VLT; Close-up - X-ray: NASA/CXC/Curtin University/R.Soria et al., Optical: NASA/STScI/Middlebury College/F.Winkler et al.)

[/caption]

Astronomers keeping an eye out for a supernova explosion in the nearby galaxy M83 instead witnessed a prodigious blast of another type: a new ultraluminous X-ray source, or ULX. In what scientists are calling an “extraordinary outburst,” the ULX in M83 increased in X-ray brightness by at least 3,000 times, one of the largest changes in X-rays ever seen for this type of object.

“The flaring up of this ULX took us by surprise and was a sure sign we had discovered something new about the way black holes grow,” said Roberto Soria of Curtin University in Australia, who led the new study.

The researchers say this blast provides direct evidence for a population of old, volatile stellar black holes and gives new insight into the nature of a mysterious class of black holes that can produce as much energy in X-rays as a million suns radiate at all wavelengths.

Astrophysicist Bill Blair of Johns Hopkins University, writing in the Chandra Blog, “A Funny Thing Happened While Waiting for the Next Supernova in M83,” said this galaxy, also known as the Southern Pinwheel Galaxy, “is an amazing gift of nature. At 15 million light years away, it is actually one of the closer galaxies (only 7-8 times more distant than the Andromeda galaxy), but it appears as almost exactly face-on, giving earthlings a fantastic view of its beautiful spiral arms and active star-forming nucleus.”

M83 has generated six observed supernovas since 1923, but the last one seen was in 1983. “We are overdue for a new supernova!” Blair wrote.

So, many astronomers have been observing M83, hoping to spot a new supernova, but instead saw a dramatic jump in X-ray brightness, which according to the researchers, likely occurred because of a sudden increase in the amount of material falling into the black hole.

A ULX can give off more X-rays than most “normal” binary systems in which a companion star is in orbit around a neutron star or black hole. The super-sized X-ray emission suggests ULXs contain black holes that might be much more massive than the ones found elsewhere in our galaxy.

Composite image of spiral galaxy M83. (X-ray: NASA/CXC/Curtin University/R. Soria et al., Optical: NASA/STScI/ Middlebury College/F. Winkler et al.)

The companion stars to ULXs, when identified, are usually young, massive stars, implying their black holes are also young. The latest research, however, provides direct evidence that ULXs can contain much older black holes and some sources may have been misidentified as young ones.

The observations of M83 were made over a several year period with Chandra. No sign of the ULX was found in historical X-ray images made with Einstein Observatory in 1980, ROSAT in 1994, the European Space Agency’s XMM-Newton in 2003 and 2008, NASA’s Swift observatory in 2005, the Magellan Telescope observations in April 2009 or in a Hubble image obtained in August 2009.

But in 2011, Soria and his colleagues used optical images from the Gemini Observatory and NASA’s Hubble Space Telescope and saw a bright blue source at the position of the X-ray source.

The lack of a blue source in the earlier images indicates the black hole’s companion star is fainter, redder and has a much lower mass than most of the companions that previously have been directly linked to ULXs. The bright, blue optical emission seen in 2011 must have been caused by a dramatic accumulation of more material from the companion star.

“If the ULX only had been observed during its peak of X-ray emission in 2010, the system easily could have been mistaken for a black hole with a massive, much younger stellar companion, about 10 to 20 million years old,” said co-author Blair.

The companion to the black hole in M83 is likely a red giant star at least 500 million years old, with a mass less than four times the sun’s. Theoretical models for the evolution of stars suggest the black hole should be almost as old as its companion.

Another ULX containing a volatile, old black hole recently was discovered in the Andromeda galaxy by a team led by Amanpreet Kaur from Clemson University, published in the February 2012 issue of Astronomy and Astrophysics. Matthew Middleton and colleagues from the University of Durham reported more information in the March 2012 issue of the Monthly Notices of the Royal Astronomical Society. They used data from Chandra, XMM-Newton and HST to show the ULX is highly variable and its companion is an old, red star.

“With these two objects, it’s becoming clear there are two classes of ULX, one containing young, persistently growing black holes and the other containing old black holes that grow erratically,” said Kip Kuntz, a co-author of the new M83 paper, also of Johns Hopkins University. “We were very fortunate to observe the M83 object at just the right time to make the before and after comparison.”

A paper describing these results will appear in the May 10th issue of The Astrophysical Journal.
