To The Moon, Jeremy! Canadian Astronaut Thinks Off-Planet Geology During Arctic Trip

It takes gumption to go knee-deep in mud to save a stranded rover. Or to climb up precarious slopes in search of the perfect rock. Oh, and did we mention the location is best accessible by air, with no towns nearby?

Take these challenging conditions, which Canadian astronaut Jeremy Hansen faced in the Arctic this month, and then imagine doing this on the moon. Or an asteroid. Or Mars. Scary, isn’t it? But that’s what he’s thinking of and training for as he does geology work a few times a year.

“It’s important; it provides an opportunity in a somewhat uncomfortable, risky situation when we’re doing real science,” Hansen told Universe Today of his time in Haughton Crater in Canada’s north. In fact, it’s so important to Hansen that he’s gone on similar geology trips with this Western University group three times.

Geology is now part of the package with basic astronaut training. NASA is hoping to get to the moon or an asteroid in the (relatively) near future, and there have been Congressional questions about the agency’s plans for Mars exploration. No one has firm answers yet. The astronauts, still, are preparing themselves as best as they can if the opportunity arises.

There would be vast differences between Earth exploration and heading to another location, however. Some examples:

  • Water and supplies. The team Hansen joined had nine people and 29 checked bags for an expedition that lasted just over a week. They could also get water on site at a spot not too far from their camp, reducing the load of that heavy but important substance. NASA’s long-range planning, meanwhile, envisions scenarios such as a month on the moon, Hansen said. Supplies would be an interesting and heavy challenge in that situation. “The next time we’ll go back, what we’ll really be looking to do is travel much greater distances over a longer period of time,” he said. “We’ll be living in a rover for a month, covering 100 kilometers [62 miles] or more, looking for these important outcrops that tell us the story.”
  • Geology. The Earth is an erosive force on geology: wind, rain, glaciation, water, volcanic activity and more alters the landscape. “Sometimes the rocks look very similar” even when they are different, Hansen pointed out. Other places may have different erosion processes (think micrometeroids), making the rocks look strange to Earth-trained eyes.
  • Location. The landscape itself could be challenging for collecting samples. The moon, for example, has “stuff strewn everywhere and pounded into sand”, Hansen said, meaning that astronauts might have to travel much further to see something besides regolith or moon soil. Where Hansen was in the Arctic, by contrast, the group could get to more than a dozen different outcrops in a day of walking.
  • Gravity. The moon has a sixth of the Earth’s gravity. Mars is at about 38% Earth gravity. This means that the machines would need to be designed to work in that environment. For astronauts, it’s riskier to go up slopes or do heavy work in those conditions because their center of gravity is unfamiliar. As this Apollo 17 clip shows, astronauts sometimes fell over on the moon when doing something as simple as picking up as sample bag.

Hansen’s work in Haughton Crater did turn up some similarities to work at off-Earth locations, though. His crew had to work in a compressed time situation, learning how to find representative rocks from a 14-mile (23-kilometer) wide crater. That’s the same challenge you’d find during a moon or asteroid or Mars expedition.

“We explored not the entire crater — it’s a lot of ground to cover — but we explored some key areas,” Hansen said. “What’s important for someone like me, at my stage of geologist eyes, is to see the key aspects of the crater, those being what types of rocks that are formed and where do they end up in the crater.”

When a big rock slams into the Earth, it excavates material that is normally inaccessible to a surface visitor. Hansen was encouraged to seek the oldest or genesis rocks when on his expedition because, as in other locations, they provide clues about how the solar system was formed. The hard evidence firms up our theories on what happened.

"Explored rocks, learned origins of Earth. Want to do this on Mars someday like @MarsCuriosity but with a return ticket," tweeted Canadian astronaut Jeremy Hansen, making a joking reference to the Mars One expedition. Credit: Jeremy Hansen/Twitter

It’s not only work in the field that is important, but work in the lab. In past years with Gordon Osinski‘s group at Western, Hansen has gone back to the university to talk with those looking at the rock samples. He asks if the samples were representative, easy to analyze. His goal is to do better with each expedition.

“It’s kind of like learning a fourth lagnguage,” said Hansen, who as a Canadian Space Agency astronaut is expected to speak English, French and Russian at a minimum.

“It’s one of those things — you can cram it all in, but you don’t retain a lot unless you use it repeatedly and continue to practice it. My elegant solution is I spend one, maybe two weeks total a year, working on this. It’s a good use of my time. I keep bringing it back, keep reviewing it and keep going a little further.”

Hansen has a busy summer ahead of him. He’s taking off soon for CF-18 training with the Royal Canadian Air Force, where he got his career start. (Funny enough, in his past career he used to survey the Arctic from the air during Canadian sovereignty operations.)

In September, Hansen is spending about a week underground in Sardinia, Italy as part of the European Space Agency’s ongoing CAVES expedition series. Besides geology, this also provides training in unfamiliar and dangerous environments.

Hansen has not been assigned to a flight yet, but continues to work in the International Space Station operations branch in Houston and to represent the Astronaut Office in operational meetings. Also in training is his colleague David Saint-Jacques. Both astronauts were selected in 2009.

The next Canadian spaceflight is expected to happen around 2018, but could be earlier depending on ongoing negotiations by the Canadian Space Agency.

Isotopes May One Day Aid In Planet Search

Modeling results show where the injected gas and dust ended ups only 34 years after being injected at the disk’s surface. It was injected 9 astronomical units from the central prostar and is now in the disk’s midplane. The outer edge shown is 10 astronomical units from the central prostar. Mixing and transport are still underway and the underlying spiral arms that drive the mixing and transport can be seen. Image courtesy of Alan Boss.

When we consider samples from the solar nebula, we think about comets and meteorites. These materials come from our solar system’s beginning, but the clues they give to formation don’t always mesh neatly. Thanks to a new study done by Carnegie’s Alan Boss, we’re now able to take a look at the Sun’s formation through a set of theoretical models. This work could not only help explain some of the differences we’ve discovered, but could also point to habitable exoplanets.

At the present time, a way to look back at the solar system’s early period is to theorize about tiny pockets of crystalline particles found in comets. These particles were forged at high temperatures. An alternate method of studying solar system formation is to analyze isotopes. These variants of elements carry the exact same number of protons, but contain a different number of neutrons. Unlike the crystalline particles, we can get our hands on samples of isotopes, because they are found in meteorites. As they decay, they turn into different elements. However, the initial number of isotopes can clue researchers as to their origin and how they might have journeyed across the neophyte solar system.

“Stars are surrounded by disks of rotating gas during the early stages of their lives.” says the Carnegie team. “Observations of young stars that still have these gas disks demonstrate that Sun-like stars undergo periodic bursts, lasting about 100 years each, during which mass is transferred from the disk to the young star.”

However, the study isn’t cut and dried just yet. The study of both particles and isotopes from comets and meteorites still present a somewhat confused look at early solar system formation. It would appear there’s more to the picture than just a single path of matter from the protoplanetary disk to the parent star. The crystalline grains found in comets are heat-formed and they signal that considerable mixing and outward flow occurred from materials close to the parent star and out to the perimeter of the system itself. Certain isotopes, such as aluminum, support this theory, but others, like oxygen, defy such a neat explanation.

According to the news release, Boss’ new model shows how a period of slight gravitational instability in the gas disk surrounding a proto-Sun about to go into an outburst phase, could account for these findings. What’s more, the models also predict this could happen with a wide variety of both mass and disk sizes. It shows that instability can “cause a relatively rapid transportation of matter between the star and the gas disk, where matter is moved both inward and outward. This accounts for the presence of heat-formed crystalline particles in comets from the solar system’s outer reaches.”

So what of aluminum? According to Boss’ model, the ratios of aluminum isotopes can be explained. It would appear the original isotope was imparted during a singular event – such as an exploding star sending a shock wave both inward and outward in the protoplanetary disk. As far as oxygen goes, it can be present in different pattern because it originated from sustained chemical reactions natural to the outer solar nebula and did not just happen as a singular event.

“These results not only teach us about the formation of our own solar system, but also could aid us in the search for other stars orbited by habitable planets,” Boss said. “Understanding the mixing and transport processes that occur around Sun-like stars could give us clues about which of their surrounding planets might have conditions similar to our own.”

Watch for the Delta Aquarid Meteors This Weekend

The Southern Delta Aquarid radiant, looking southeast at 2AM local from latitude 30 degrees north on the morning of July 30th. (Created by the author in Starry Night).

The meteor shower drought ends this weekend.

The northern summer hemisphere meteor season is almost upon us. In a few weeks’ time, the Perseids — the “Old Faithful” of meteor showers — will be gracing night skies worldwide.

But the Perseids have an “opening act”- a meteor shower optimized for southern hemisphere skies known as the Delta Aquarids.

This year offers a mixed bag for this shower. The Delta Aquarids are expected to peak on July 30th and we should start seeing some action from this shower starting this weekend.

The Moon, however, also reaches Last Quarter phase the day before the expected peak of the Delta Aquarids this year on July 29th at 1:43PM EDT/17:43 Universal Time (UT). This will diminish the visibility of all but the brightest meteors in the early morning hours of July 30th.

A cluster of meteor shower radiants also lies nearby. The Eta Aquarids emanate from a point near the asterism known as the “Water Jar” in the constellation Aquarius around May 5th. Another nearby but weaker shower known as the Alpha Capricornids are also currently active, with a zenithal hourly rate (ZHR) approaching the average hourly sporadic rate of 5. And speaking of which, the antihelion point, another source of sporadic meteors, is nearby in late July as well in eastern Capricornus.

The Delta Aquarids are caused by remnants of Comet 96P/Machholz colliding with Earth’s atmosphere. The short period comet was only discovered in 1986 by amateur astronomer Donald Machholz. Prior to this, the source of the Delta Aquarids was a mystery.

The Delta Aquarids have a moderate atmospheric entry velocity (for a meteor shower, that is) around an average of 41 kilometres a second. They also have one of the lowest r values of a major shower at 3.2, meaning that they produce a disproportionately higher number of fainter meteors, although occasional brighter fireballs are also associated with this shower.

The Delta Aquarids are also one the very few showers with a southern hemisphere radiant. It’s somewhat of a mystery as to why meteor showers seem to favor the northern hemisphere. Of the 18 major annual meteor showers, only four occur below the ecliptic plane and three (the Alpha Capricornids, and the Eta and Delta Aquarids) approach the Earth from south of the equator. A statistical fluke, or just the product of the current epoch?

In fact, the Delta Aquarids have the most southern radiant of any major shower, with a radiant located just north of the bright star Fomalhaut in the constellation Piscis Austrinus near Right Ascension 339 degrees and Declination -17 degrees.  Researchers have even broken this shower down into two distinct northern and southern radiants, although it’s the southern radiant that is the more active during the July season.

Together, this loose grouping of meteor shower radiants in the vicinity is known as the Aquarid-Capricornid complex.  The Delta Aquarids are active from July 14th to August 18th, and unlike most showers, have a very broad peak. This is why you’ll see sites often quote the maximum for the shower at anywhere from July 28th to the 31st. In fact, you may just catch a stray Delta Aquarid while on vigil for the Perseids in a few weeks!

The shower was first identified by astronomer G.L. Tupman, who plotted 65 meteors associated with the stream in 1870. Observations of the Delta Aquarids were an off-and-on affair throughout the early 20th century, with many charts erroneously listing them as the “Beta Piscids”. The separate northern and southern radiants weren’t even untangled until 1950. The advent of radio astronomy made more refined observations of the Delta Aquarids possible. In 1949, Canadian astronomer D.W.R. McKinley based out of Ottawa, Canada identified both streams and pinned down the 41 km per second velocity that’s still quoted for the shower today.

Further radio studies of the shower were carried out at Jodrell Bank in the early 1950’s, and the shower gave strong returns in the early 1970’s for southern hemisphere observers even with the Moon above the horizon, with ZHRs approaching 40. The best return for the Southern Delta Aquarids in recent times is listed by the International Meteor Organization as a ZHR of about 40 on the morning of July 28th, 2009.

A study of the Delta Aquarids in 1963 by Fred Whipple and S.E. Hamid reveal striking similarities between the Delta Aquarids and the January Quadrantids & daytime Arietid stream active in June. They note that the orbital parameters of the streams were similar about 1,400 years ago, and the paths are thought to have diverged due to perturbations from the planet Jupiter.

Observing the Delta Aquarids can serve as a great “dry run” for the Perseids in a few weeks. You don’t need any specialized gear, simply find a dark site, block the Moon behind a building or hill, and watch.

Photographing meteors is similar to doing long exposures of star trails. Simply aim your tripod mounted DSLR camera at a section of sky and take a series of time exposures about 1-3 minutes long to reveal meteor streaks. Images of Delta Aquarids seem elusive, almost to the point of being mythical. An internet search turns up more blurry pictures of guys in ape suits purporting to be Bigfoot than Delta Aquarid images… perhaps we can document the “legendary Delta Aquarids” this year?

Spacesuited Astronauts Climb Aboard Boeing CST-100 Commercial Crew Capsule for Key Tests

A pair of NASA astronauts donned their spacesuits for key fit check evaluations inside a test version of the Boeing Company’s CST-100 commercial ‘space taxi’ which was unveiled this week for the world’s first glimpse of the cabin’s interior.

Boeing is among a trio of American aerospace firms, including SpaceX and Sierra Nevada Corp, seeking to restore America’s capability to fly humans to Earth orbit and the space station using seed money from NASA’s Commercial Crew Program (CCP).

Astronauts Serena Aunon and Randy Bresnik conducted a day long series of technical evaluations inside a fully outfitted, full scale mock up of the CST-100, while wearing NASA’s iconic orange launch-and-entry flight suits from the space shuttle era.

During the tests, Boeing technicians monitored the astronauts ergonomic ability to work in the seats and move around during hands on use of the capsules equipment, display consoles and storage compartments.

The purpose of the testing at Boeing’s Houston Product Support Center is to see what works well and what needs modifications before fixing the final capsule design for construction.

“It’s an upgrade,” said astronaut Serena Aunon at the evaluation. “It is an American vehicle, of course it is an upgrade.”

Former NASA Astronaut Chris Ferguson, the commander of the final shuttle flight (STS-135) by Atlantis, is leading Boeing’s test effort as the director of Boeing’s Crew and Mission Operations.

“These are our customers. They’re the ones who will take our spacecraft into flight, and if we’re not building it the way they want it we’re doing something wrong,” said Ferguson.

“We’ll probably make one more go-around and make sure that everything is just the way they like it.”

The CST-100 is designed to carry a crew of up to 7 astronauts, or a mix of cargo and crew, on missions to low-Earth orbit (LEO) and the International Space Station (ISS) around the middle of this decade.

Although it resembles Boeing’s Apollo-era capsules from the outside, the interior employs state of the art modern technology including sky blue LED lighting and tablet technology.

Nevertheless Boeing’s design goal is to keep the flight technology as simple as possible.

“What you’re not going to find is 1,100 or 1,600 switches,” said Ferguson. “When these guys go up in this, they’re primary mission is not to fly this spacecraft, they’re primary mission is to go to the space station for six months. So we don’t want to burden them with an inordinate amount of training to fly this vehicle. We want it to be intuitive.”

The CST-100 crew transporter will fly to orbit atop the venerable Atlas V rocket built by United Launch Alliance (ULA) from Launch Complex 41 on Cape Canaveral Air Force Station in Florida.

Boeing is aiming for an initial three day manned orbital test flight of the CST-100 during 2016, says John Mulholland, Boeing vice president and program manger for Commercial Programs.

The 1st docking mission to the ISS would follow in 2017 – depending on the very uncertain funding that Congress approves for NASA.

The Atlas V was also chosen to launch one of Boeing’s commercial crew competitors, namely the Dream Chaser mini shuttle built by Sierra Nevada Corp.

NASA’s CCP program is fostering the development of the CST-100 as well as the SpaceX Dragon and Sierra Nevada Dream Chaser to replace America’s capability to launch humans to space that was lost following the retirement of NASA’s space shuttle orbiters two years ago in July 2011.

Since 2011, every American astronaut has been 100% dependent on the Russians and their Soyuz capsule to hitch a ride to the ISS.

“We pay one of our [ISS] partners, the Russians, $71 million a seat to fly,” says Ed Mango, CCP’s program manager. “What we want to do is give that to an American company to fly our crews into space.”

Simultaneously NASA and its industry partners are designing and building the Orion crew capsule and SLS heavy lift booster to send humans to the Moon and deep space destinations including Near Earth Asteroids and Mars.

Astrophotographer Cory Schmitz braved a brown bear in order to capture some wonderful images of the full Moon rise on July 22, 2013. This composite shows a series of images of the moonrise, and below is a beautiful timelapse.

This perigee Moon, a.k.a “Super Moon” was the third and final of the big full Moons for 2013. However, as astrophysicist Neil DeGrasse Tyson mentioned on Twitter, it is “Okay to call tonight’s Full Moon “super” but only if you would call a 13-inch pizza “super” compared with a 12-inch pizza.”

You can catch more of Cory with Fraser on the Virtual Star Parties on Sunday nights. Below are a couple of more great scenes from Cory’s full Moon experience:

How Can We Stop An Asteroid?

“It’s like looking for a charcoal briquette in the dark,” says Bill Nye the Science Guy in this new video from AsapSCIENCE… except he’s talking about briquettes hundreds of meters wide whizzing past our planet upwards of 8, 9, 10, even 20 kilometers per second — and much, much denser than charcoal.

Near-Earth asteroids are out there (and on occasion they even come in here) and, as the planet’s only technologically advanced spacefaring species, you could say the onus is on us to prevent a major asteroid impact from occurring, if at all possible — whether to avoid damage in a populated area or the next mass extinction event. But how can we even find all these sooty space rocks and, once we do, what can be done to stop any headed our way?

Watch the video (and then when you’re done, go visit the B612 Foundation’s Sentinel page to learn more about an upcoming mission to bag some of those space briquettes.)

Kepler Team Has Some Success in Reaction Wheel Recovery Attempt

In May of this year, the Kepler planet-hunting telescope lost its ability to precisely point toward stars, putting its exoplanet search in jeopardy. Two of the four reaction wheels failed, and Kepler scientists say the spacecraft needs at least three reaction wheels to be able to point precisely enough to continue the mission. In the latest update from Kepler, mission manager Roger Hunter says that the team has made a little headway and had initial success in testing the two failed reaction wheels. But the big test will come later to see how much friction the two wheels generate with continued use.

On Thursday, July 18, 2013 the team initiated recovery tests on the spacecraft’s two failed wheels in order to characterize how the two wheels (Reaction Wheels (RW) 4 and 2) operated and to determine if either could be returned to full use.

RW4 did not spin in the positive (or clockwise) direction but the wheel did spin in the negative (or counterclockwise) direction. Wheel 4 is thought to be the more seriously damaged of the two, Hunter said.

Then, on Monday, July 22 the team tested RW2, and that wheel responded positively to test commands and spun in both directions.

“Over the next two weeks, engineers will review the data from these tests and consider what steps to take next,” Hunter said. “Although both wheels have shown motion, the friction levels will be critical in future considerations. The details of the wheel friction are under analysis.”

Too much friction from the reaction wheels can cause vibration and impact the pointing precision of the telescope.

Kepler has found over 2,700 planetary candidates, with 130 confirmed planets, from the size of Earth’s moon to larger than Jupiter. There are two years of data that has yet to be combed through to detect the faint periodic dimming of distant starlight – the telltale sign of a planet transiting the face of its host star.

Still, the loss of Kepler would be a blow to the search for planets orbiting other stars. Earlier this year, Kepler team members said if the spacecraft could no longer do planet-hunting, there’s a chance it could do something else , such as asteroid hunting or other astronomical observations…just something that doesn’t need as precise ability for pointing.

Going for gold in the Sochi Winter Olympics could earn athletes some out-of-this-world rocks.

Athletes who top the podium on Feb. 15, 2014 will receive special medals with pieces of the Chelyabinsk meteor that broke up over the remote Russian community on that day in 2013, according to media reports.

“We will hand out our medals to all the athletes who will win gold on that day, because both the meteorite strike and the Olympic Games are the global events,” stated Chelyabinsk Region Culture Minister Alexei Betekhtin in a Ria Novosti report.

The reported sports that will receive these medals include:

  • Women’s 1,000 meter and men’s 1,500 meter short track;
  • Men’s skeleton;
  • Women’s cross-country skiing relay;
  • Men’s K-125 ski jump;
  • Men’s 1,500 meter speed skating;
  • Women’s super giant slalom.

The 55-foot (17-meter) meteor’s airburst in February damaged buildings, causing injuries and fright among those in the region. As astronomers have been collecting fragments and calculating the orbit of the fireball, the incident put renewed attention on the need to monitor space rocks that could threaten the Earth.
