NASA’s revolutionary Curiosity rover is celebrating 90 Sols on Mars by snapping amazing self-portraits (see our mosaics above and below) and biting into the Red Planet’s surface to accomplish unprecedented scientific analysis of an alien world.

Nov. 6 marked a major milestone in Curiosity’s daring and evolving mission in search of signs of life. This is the three month anniversary of her toiling on the breathtaking Martian surface since the hair-raising pinpoint touchdown on Aug. 6 inside Gale Crater at the foothills of a humongous and gorgeous layered mountain that likely holds the key to understanding Mars watery past and 4 billion plus year evolution.

The never before seen mosaic vista above shows a matchless self portrait of Curiosity’s Mastcam ‘head’ and body combined with a thrilling scene of her target destination – Mount Sharp – the layered mound of sediments that could unlock the mysteries of whether Mars ever possessed habitats favorable for the evolution of life, past or present.

Last week on Sols 84 & 85 (Oct 31 & Nov 1) Curiosity took hundreds of high resolution color images with the Mars Hand Lens Imager (MAHLI) camera – located at the end of the 7 foot (2.1 m) long robotic arm – thus affording us a breathtaking portrait view of our emissary from Earth to Mars.

Our Sol 85 self-portrait mosaic was stitched together by the imaging team of Ken Kremer and Marco Di Lorenzo. Last week NASA released the first self portrait mosaic of the Sol 84 MAHLI camera imagery that included the left flank of 3 mile (5 km) Mount Sharp.

The Curiosity team spent considerable effort to build the imaging sequences and then remotely maneuver the robotic arm to precisely collect the raw images and transmit them to Earth.

Previously the team used the MAHLI camera to photograph Curiosity’s underbelly (see our mosaic).

For the past month Curiosity has been hunkered down at “Rocknest” ripple which lies at the edge of “Glenelg” – her first major science destination – and that sits at the natural junction of three types of geologically diverse terrain.

Rocknest afforded the perfect type of fine grained Martian dust to carry out the first test scoops of Martian soil and then used the material to thoroughly cleanse the robots’ sample processing system of residual Earthy contamination and then ingest the first samples into the robots pair of analytical chemistry labs – CheMin and SAM.

Curiosity has eaten into Rocknest 4 times so far and delivered two samples to the CheMin (Chemistry and Mineralogy) instrument for analysis.

Scoop sample #5 should deliver the first solid material to SAM (Sample Analysis at Mars) sometime in the next week or so.

SAM is specifically engineered to search for organic molecules – the building blocks of life as we know it. CheMin uses X-ray diffraction techniques to accurately determine the mineralogical composition of pulverized and sieved red planet soil and rock samples.

Curiosity’s key science finding during the first 90 Sols is the discovery of evidence for an ancient Martian stream bed at three different locations along the short route she has traversed to date.

Curiosity found a trio of outcrops of stones cemented into a layer of conglomerate rock. Hip deep liquid water once flowed vigorously on the floor of Gale Crater billions of years ago. Liquid water is a prerequisite for the origin of life.

Since the landing, some 400 members of the Curiosity science team had been camped out at Mission Control at NASA’s Jet Propulsion Lab in Pasadena, Calif to efficiently coordinate the rovers surface planning and operations.

With the first 90 Sols now successfully behind them and with Curiosity operating in tip top shape, most of the science team has just departed JPL and returned to their home institutions scattered across the globe, mostly in North America and Europe.

The 1 ton SUV sized Curiosity rover has taken over 22,000 pictures thus far and is funded for a 2 year primary mission.

Want to Name an Exoplanet? Uwingu Has a Plan

Screenshot from the Uwingu exoplanet naming website.

Astronomers have now discovered nearly 1,000 planets orbiting other stars, and right now these exoplanets all have boring, license-plate-like names, such as HD85512 and GJ 436 instead of endearing, “real” planet names that might offer hints of what that world could be like. And recall the recent extrapolation of how many habitable planets might be in the Milky Way? A team using the ESO’s HARP’s spectrograph determined there might be upwards of 160 billion worlds out there for us to find, and perhaps eventually name. How might we come up with that many names?

Uwingu, a startup company that is hoping to use innovative ways to fund space and astronomy research, has an idea of how to do that. Their first commercial project is to challenge people to create a ‘baby book of planet names’ for all these planets, as suggestions for future names for other worlds.

“The many, many planets discovered across the galaxy in past 20 years are a tribute to our natural human desire to explore beyond the horizon,” said noted planet hunter Dr. Geoff Marcy of the University of California at Berkeley, who is also an advisor for Uwingu. “Now people all over the world can participate in these discoveries in a new way, giving identities and even personality to billions of planets in our galaxy for the first time.”

How does this raise money for space science? Submitting suggestions for names cost $.99 each, and Uwingu will use proceeds from this project and future ones to create funds for grants that space researchers, space educators, and project teams can apply to use.

Uwingu’s first project is technically now in “beta testing,” and in a press release, the organization said the public can participate immediately, helping to generate a new source of funds for space exploration, research, and education.

But it doesn’t end with just suggestions. People can vote on the top names (each vote also costs $.99), and as Uwingu CEO and founder Alan Stern told Universe Today, they are hoping the voting goes viral among the social media savvy.

“This is a way for people everywhere to connect with space,” he said. “You can suggest a name and tell all your friends to vote, and the top names will be the first to be used. If you nominate the name of someone famous, hopefully they’ll get in on the excitement and ask their fans to vote, too.”

The Uwingu team suggests nominating planet names for your favorite town, state, or country, your favorite sports team, music artist, or hero, your favorite author or book, your school, your company, for your loved ones and friends, or even for yourself.

The names won’t be officially approved by the International Astronomical Union, but Stern said they will be are similar to the names given to features on Mars by the mission science teams (such as the “Jake Matijevic” rock recently analyzed by the Curiosity rover) that everyone ends up using. This also solves the problem of how to come up with names, a task that the IAU has yet to discuss.

Initial reactions to the planet naming project – and to Uwingu itself — have been mixed. During their Indigogo fundraising, the Uwingu team didn’t disclose what types of things they would be selling or doing to raise funds, which was a concern to some in the space and astronomy community who normally support almost any space-related initiative. In a previous interview with UT, Stern said being secretive was a way to generate interest and likened it to how Apple announces a new product.

While there seems to be excitement about the opportunity to suggest names for exoplanets (as of this writing 74 names had been nominated, with numerous votes for each name), some early reactions have been that this might be similar to the ‘name a star’ registries that are unofficial and quite expensive.

IAU’s stance on naming exoplanets has been that since it appears there are going to be so many of them, naming them will be difficult. However, in an email reply, the former president of the IAU Planetary Systems Science body, Karen Meech said that at the IAU meeting in Beijing this summer there was discussion about the need to set up a group to look into the issue of exoplanet names.

And Meech did confirm that since the IAU is the only scientifically recognized arbiter of astronomical names, any contests for names from the public will not be officially recognized by the scientific community.

But if the problem is in the amount of names that will be required, that’s where Uwingu’s crowd sourcing idea seems to fit the need.

And for those who are critical of Uwingu’s methods, Uwingu is so far the only group or organization to step forward with innovative, out-of-the-box ways to try and solve what seems to be a continuous, perennial problem: how to fund creative space and astronomy projects and move beyond the old tried and not always true methods of relying on government grants and subsidies or angel donors.

Uwingu is at least trying something different, and it will be interesting to see how this plays out. Stern said earlier that Uwingu’s projects would appeal to the general public, not just the space and astronomy community, to provide a bigger marketplace for their projects. He indicated Uwingu will be coming out with another project in a few months.

We humans love to name things: we name our cars, spacecraft and rocks, craters and hills on other planets. NASA has had contests to name missions, rovers, and modules on the ISS, all of which has generated excitement among the public. Science and science fiction fans have expressed disappointment at the names given to exoplanets so far (they certainly aren’t as intriguing as names we’ve come to love like Tatooine, Pandora, Vulcan or Hoth.) Uwingu is using that innate need/love of naming things to try and move space science and astronomy into a new era.

Kansas Cosmosphere Vote Passes on Election Night

As an update to our story yesterday, more than 70 per cent of residents in Hutchinson, KS voted to keep tax money flowing into the Kansas Cosmosphere and Space Center. The museum is located in the community, which is about an hour north of Wichita.

Museum officials were closely watching the vote Tuesday night, which took place at the same time as the U.S. general election for convenience’s sake.

The Cosmosphere gets 18% of its revenues from the city sales tax, which puts 33% of a quarter-cent aside for the Cosmosphere. Additional sales tax funds go to a nearby salt museum, as well as other city initiatives.

The tax vote takes place every five years, and this is the fifth time the measure has been approved, the museum noted. The votes tallied showed 8,935 people in favour and 3,635 opposed.

“The community’s response to the Cosmosphere’s request for continued commitment to the quarter-cent sales tax is greatly appreciated,” said Becky Christner, the Cosmosphere’s marketing and sales manager, in an e-mail to Universe Today.

“We look forward to continuing to serve the community as we work daily to succeed at our mission of honoring the past and inspiring the future of space exploration.”

The Cosmosphere is looking to expand its restoration, exhibition and fabrication customers in the coming years to bring in more revenue to the museum.

Past projects the Cosmosphere is known for:

– Rebuilding the Apollo 13 Odyssey spacecraft, which was torn apart for an accident investigation following a near-fatal explosion;

– Restoring the Liberty Bell 7 spacecraft, which sank at the end of its mission in space, and spent decades in a shallow part of the Atlantic Ocean;

– Film and television productions such as Apollo 13, From the Earth to the Moon and Magnificent Desolation.

The Milky Way’s Black Hole Shoots Out Brightest Flare Ever

This false-color image shows the central region of our Milky Way Galaxy as seen by Chandra. The bright, point-like source at the center of the image was produced by a huge X-ray flare that occurred in the vicinity of the supermassive black hole at the center of our galaxy.

For some unknown reason, the black hole at the center of the Milky Way galaxy shoots out an X-ray flare about once a day. These flares last a few hours with the brightness ranging from a few times to nearly one hundred times that of the black hole’s regular output. But back in February 2012, astronomers using the Chandra X-Ray Observatory detected the brightest flare ever observed from the central black hole, also known as Sagittarius A*. The flare, recorded 26,000 light years away, was 150 times brighter than the black hole’s normal luminosity.

What causes these outbursts? Scientists aren’t sure. But Sagittarius A* doesn’t seem to be slowing down, even though as black holes age they should show a decrease in activity.

Earlier this year, a group of researchers said that the outbursts may come from asteroids or even wandering planets that come too close to the black hole and they get consumed. Basically, the black hole is eating asteroids and then belching out X-ray gas.

Astronomers involved in this new observation seem to concur with that line of thinking.

“Suddenly, for whatever reason, Sagittarius A* is eating a lot more,” said Michael Nowak, a research scientist at MIT Kavli and co-author of a new paper in the Astrophysical Journal. “One theory is that every so often, an asteroid gets close to the black hole, the black hole stretches and rips it to pieces, and eats the material and turns it into radiation, so you see these big flares.”

Astronomers detect black holes by the light energy given off as they swallow nearby matter. The centers of newborn galaxies and quasars can appear extremely bright, giving off massive amounts of energy as they devour their surroundings. As black holes age, they tend to slow down, consuming less and appearing fainter in the sky.

“Everyone has this picture of black holes as vacuum sweepers, that they suck up absolutely everything,” says Frederick K. Baganoff, another co-author from MIT. “But in this really low-accretion-rate state, they’re really finicky eaters, and for some reason they actually blow away most of the energy.”

While such events like this big blast appear to be relatively rare, Nowak suspects that flare-ups may occur more frequently than scientists expect. The team has reserved more than a month of time on the Chandra Observatory to study Sagittarius A* in hopes of identifying more flares, and possibly what’s causing them.

“These bright flares give information on the flaring process that isn’t available with the weaker ones, such as how they fluctuate in time during the flare, how the spectrum changes, and how fast they rise and fall,” said Mark Morris from UCLA. “The greatest importance of this bright flare may be that it builds up the statistics on the characteristics of strong flares that can eventually be used to [identify] the cause of such flares.”

Even more intriguing to Baganoff is why the black hole emits so little energy. In 2003, he ran the very first observations with the then-new Chandra Observatory, and calculated that, given the amount of gas in its surroundings, Sagittarius A* should be about a million times brighter than it is — a finding that suggested the black hole throws away most of the matter it would otherwise consume.

The physics underlying such a phenomenon remain a puzzle that Baganoff and others hope to tease out with future observations.

“We’re really studying the great escape, because most of the gas escapes, and that’s not what we expect,” Baganoff says. “So we’re piecing out the history of the activity of the center of our galaxy.”

How Today’s Election Could Affect the Kansas Cosmosphere

The Kansas Cosmosphere and Space Center. (Elizabeth Howell)

Hutchinson, KS — While the nation is polarized between choosing Barack Obama or Mitt Romney as the next American president, voters going to the polls in this city of 40,000 will have another matter to weigh during elections today.

Along with their ballot, residents will consider whether the Kansas Cosmosphere and Space Center will continue to receive funding from city coffers. Since it represents 18% of revenues for the science museum, Cosmosphere president Jim Remar says his colleagues have been paying close attention.

The city sales tax sets aside 33% of a quarter-cent for the Cosmosphere, and some additional funding for a nearby underground salt museum and other city initiatives. Money to the museum goes for general operations.

“I feel good that it’s going to pass, although we do have some nervous moments,” Remar says. Supporters of the tax have been spreading the word through radio, billboards, editorials in local newspapers and any other means possible to get out the word.

Sales tax funding for the Cosmosphere renews every five years, with the current iteration set to expire in 2014. The city tries to get the vote out for the sales tax at the same time as the general election, for convenience and financial sake.

While 18% of the museum’s funding lie in the hands of voters, Remar is trying to increase the share of the remaining 82% under the Cosmosphere’s control.

Getting visitors out to the museum is always a challenge; it’s an hour from the nearest major center (Wichita), a city that itself is many hours’ drive from any city to speak of. Still, the museum brings in 120,000 people every year, an attendance figure that includes space camps, museum visits and other events.

For the city itself, though, the museum is a jewel: “I can’t think of any other town of 40,000 that has such a facility,” says Remar, speaking proudly of how he grew up in the area, left and then chose to come back to help lead the museum’s management. His focus now is on trying to bring in business connections to enhance the Cosmosphere’s power in the community.

One of the most promising aspects is the Cosmosphere’s restoration and fabrication facility. The museum is perhaps most famous for putting the pieces of the Apollo 13 Odyssey spacecraft back together around the same time the movie came out in 1995. This was no easy task, as Odyssey was disassembled and scattered during an investigation into a near-fatal explosion aboard the spacecraft in 1970.

The Cosmosphere required the Smithsonian’s help as the museum hunted through NASA centers, contract facilities and other spots for months in search of missing pieces. More than 85% of the spacecraft, which is on display at the Cosmosphere, was retrieved. The rest of the components came from spares and other odd pieces the Cosmosphere could find.

Restoration capabilities came out of necessity, Remar says. In the mid-1980s, the museum had a need to put spacecraft on display and spiffy them up for visitors. As other museums had the same requirement, the Cosmosphere gradually built out capabilities in restoration.

“It’s not something where somebody can come in a day and do it. It is a lot of trial and error,” Remar says of the employees who work in the facility. The lead mechanic has been around for 14 years, though, and there are two other workers with him who have adapted well over the years.

Cosmosphere officials realized there are only so many spacecraft to restore, and added exhibitions, replication and fabrication to their capabilities. This positioned them well for a surge of Hollywood films and other productions in the 1990s, such as Apollo 13, HBO’s From the Earth to the Moon, a short-lived TV series in the ’90s called The Cape and (in the 2000s) the IMAX film Magnificent Desolation: Walking on the Moon 3D.

An individual project will cost anywhere from $10,000 to $2.5 million to build; overall revenues from this division are 15 to 20% of the museum’s coffers every year. And that could grow bigger very soon.

On Saturday, a “Science of Aliens” exhibit will open in Taipei at the National Taiwan Science Education Center. One major part is a UFO spacecraft – 19 feet wide by 7 feet tall – that the Cosmosphere built for the exhibit. It includes running lights and some alien-sounding noises.

Asia happens to be a hot economy these days compared with North America and Europe, where the Comosphere’s work historically went.

The Cosmosphere is in discussions with Taipei-based Universal Impression, a broker that negotiated the science museum work, to do more work in the future. Remar says he hopes the Cosmosphere’s presence there will serve as a calling card to other Asian clients.

“International work can explode here,” he says. “There’s a lot of potential.”

Say Hello to Asteroid 2007 PA8

Radar images of asteroid 2007 PA8 acquired on October 28, 29 and 30. (NASA/JPL-Caltech/Gemini)

Take a good look at asteroid 2007 PA8 — over the past week it was making its closest pass of Earth for the next 200 years… and NASA’s 230-foot (70-meter) -wide Deep Space Network antenna at Goldstone, California snapped its picture as it went by.

All right, maybe no “pictures” were “snapped”… 2007 PA8 is a small, dark body that only came within four million miles (6.5 million kilometers) today, Nov. 5 (0.043 AU, or 17 times the distance from Earth to the Moon). But the radar capabilities of the Deep Space Network antenna in California’s Mojave Desert can bounce radar off even the darkest asteroids, obtaining data that can be used to create a detailed portrait.

In the image above, a composite of radar data acquired on October 28, 29 and 30, we can see the irregular shape of 2007 PA8 as it rotates slowly — only once every 3-4 days. The perspective is looking “down” at the 1-mile (1.6-km) -wide asteroid’s north pole, showing ridges and perhaps even some craters.

Although classified as a Potentially Hazardous Asteroid (PHA) by the IAU’s Minor Planet Center the trajectory of 2007 PA8 is well understood. It is not expected to pose any impact threat to Earth in the near or foreseeable future.

2007 PA8 was discovered by LINEAR on August 9, 2007.
