NASA Group Achievement Award

As pictured above, five Lassonde researchers from the Department of Earth and Space Science and Engineering (ESSE) were presented with certificates by NASA “For exceptional technical innovations and execution of rover surface operations leading to numerous, profound new discoveries about the ancient climate and habitability of Mars.” From left to right these are Casey A. Moore (PhD Candidate), Dr. Christina L. Smith (Postdoctoral Fellow), Prof. John E. Moores, Jacob Kloos (PhD Candidate) and Dr. John Burton (absent from photo).

 

Prof. John Moores and four other researchers in his Planetary Volatiles Laboratory from the Lassonde School of Engineering have been presented with the NASA Group Achievement Award for their contributions to the Mars Science Laboratory’s (popularly known as the Curiosity Rover) first extended mission, which completed in 2016.

 

The research group is directly involved with rover operations, with students helping to decide each day which tasks the spacecraft will carry out on Mars. Once those tasks are completed, scientific measurements are taken and the data are returned to Earth, the same students complete the analysis required to yield new discoveries, such as the water-ice clouds glimpsed above Gale Crater by the Group in August.

 

“It’s a great feeling to be recognized for what the team has accomplished, but the work of exploring Mars and its past and present environment continues!” noted Moores, whose students are also a part of the 2nd Extended Mission of Curiosity, currently underway.

Call for Projects for ENG4000

Dear colleague,

As the course directors for the capstone Engineering course at the Lassonde School of Engineering, we are looking to develop cross-campus collaborations for our students and yours for the upcoming academic year. The capstone course is a 2-semester project course taken by our 4th year students to design, develop and test an Engineering system. As part of our “Renaissance Engineering” brand, we are keen to encourage our students to recognize the importance of cross-disciplinary understanding and collaboration to come up with solutions to today’s most challenging complex problems, and would be keen to include collaborative projects with your department in our proposed capstone projects.

Last year we proposed 4 such projects (one with Music to develop an electronic flute, one with Psychology to develop a virtual reality system for Orangutans, one with the teaching commons to develop a pedagogy-support app and one with our own student services to develop a “social kiosk” for students), with our students selecting two of these. This year, we would be interested to propose more such projects. At the simplest level, these can consist of a faculty member or student / student group acting as a system user, helping our students understand the user need for a system, and working with our students to develop a solution that meets that need. If you may be interested in a different type of collaboration, however, that may benefit your department or students in another way, we would also be interested to discuss this with you.

Projects are supervised by us as course directors, along with a dedicated faculty supervisor from Lassonde and an industry adviser, and students are required to go through traditional engineering project gate reviews through the year as they develop their solutions. Whilst proposing a project is not a guarantee that a student team will select it, our students very much appreciate projects proposed from real-world users. The level of support or interaction required from your department or students can be as minimal as proposing a project or much more extensive if desired. The 2017-2018 capstone course starts in September, but we are looking to shortlist projects by early August to ensure they meet our academic requirements and that we can identify suitable supervisors and industry advisers for every project by September. If you have a possible project you may want to propose, or would like to know more about the capstone course at York, please do not hesitate to contact us.

Yours faithfully,

Franz Newland (ESSE), Hossam Sadek (Mechanical), James Smith (EECS)

Earth and Space Science Masters student Tim (Kaiti) Jiang and supervisor Mark Gordon spent the last two weeks of July installing an instrumented 30m tall telescoping  tower in Northern Alberta.

The York Athabasca Jack Pine (YAJP) tower is situated in the middle of the boreal forest north of Fort McMurray, surrounded by oil sands mining and upgrading  facilities.  Measurements on the tower include aerosols, black carbon, dust and particulate, ozone, CO2, radiation (PAR, UV, SW, and LW), temperature, moisture, winds, and turbulence.

The tower will remain in the forest for at least a year and will send data back to York with a cellular modem.  This study will help us understand how pollutants from the oil sands facilities interact with the forest environment and how turbulence and pollutant mixing develops in forest canopies.

Talking Mars in Montréal

From July 17-19, three members of Prof. John Moores’ Planetary Volatiles Laboratory – PDF Dr. Christina Smith, MSc. Candidate Charissa Campbell and Undergraduate Researcher Brittney Cooper – attended the semi-annual Science Team Meeting of the Mars Science Laboratory Rover (better known as Curiosity). For the first time since Curiosity’s successful landing in August of 2012 the meeting was back on Canadian soil at the CSA’s headquarters in St. Hubert, just outside of Montréal. Over 400 scientists work on the $2.5 Billion mission, supporting daily operations, designing experiments using the spacecraft’s 10 primary instruments (plus 12 engineering cameras) and analyzing the data returned. More than 100 of these researchers from around the world made the trek out to the CSA to attend in person.

While the majority of the scientists who work on the mission have a geological focus, there are a few of us who specialize in the modern Martian environment. The particular speciality of the PVL group is atmospheric imaging using the rover’s Engineering Cameras.  Presentations by the York-based group on our results discussing clouds, dust, winds and the chemistry of the atmosphere were well received by other members of the Team. We also identified ways in which the atmospheric scientists and the geologists can work together to enhance our understanding of Martian processes, past and present.

Five years and 17 km into its mission, the rover remains healthy despite some dents, tears and a patina of dust. While the robot is showing its age, with that age comes wisdom. To date, we have published nearly 300 papers including several dozen in high impact venues such as Science, Nature and Geophysical Research Letters. For a sampling of these results, click here. Even as these results continue to pour in, there are still important discoveries that await us as we climb higher still along the flank of Aeolus Mons.

An Interview: Sandra Sinayuk

img_7472What are your professional aspirations?

As you know, I am going to be starting my MClSc in Audiology this September at Western! I’m not sure yet if I will want to specialize, but I want to work in a hospital setting after I graduate.

What do you like the most about York?

The potato wedges from the Bluemont Bistro. I like all of the friends I’ve made and all of the really nice people that I’ve met in my 4 years here.

Favourite building at York?

The Lassonde building, because it has a Freshii.

Which Lassonde Engineering program would you do if you had to?

Civil, my Mom did Civil ages ago, so she could help me!

Where would you like to travel?

AUSTRALIA – I’ve been in love with it since 1st year and haven’t yet been able to go. Specifically: Brisbane, Sunshine Coast, Gold Coast, Cairns, Melbourne, and Adelaide. The UK would be really cool too, because of all the castles.

If you were a breakfast cereal, which would you be?

A healthy nutty one, because I’m such a health nut! (haha)

If you were an animal, which would you be?

I would be a quokka, because they are endemic to Australia, so that would basically guarantee me Australian citizenship. They’re cute, so no one would want to hurt me and they’re marsupial, which is basically nature’s C-section.

Three items you would bring on a deserted island (no boats allowed)?

Seeds for fruits and vegetables, sunscreen, and some kind of water desalination system.

What’s your top business idea?

Starting a haunted house with optical illusions in Melbourne (where they don’t have any, according to my Aussie friend) with a cafe dungeon serving all vegan food and drink. Realistically though, I’d rather open a non-profit animal sanctuary because there’s a really big need for those.

What’s your pet peeve?

When people are late, and when I’m late. Also, when people in front of me walk extra-slowly.

Favourite movie: It’s a tie between Cowspiracy (environmental documentary) and What the Health, both are on Netflix!

Favourite fictional character: Fred and George Weasley, they’re hilarious and we would be best friends.

What’s your Harry Potter House? Gryffindor, according to Pottermore.

If you could create a Harry Potter House, what would it be called and which 5 traits would be associated with it?

Deerfox: resilient, honest, curious, sarcastic, fair.

Favourite book (that isn’t Harry Potter): “How not to Die” – it’s a nutrition book.

Favourite tree: The kind that gives me food.

Favourite food/cuisine: Cuisine: vegan food. Dish: the green poutine at Fresh restaurants (french fries, steamed baby bok choy, kale & swiss chard, roasted mushroom gravy, ‘cheese’ sauce, green onions & sunflower seeds)

Crown dish: Nice-cream (non-dairy ice cream).

Favourite quote: “When another person makes you suffer, it is because he suffers deeply within himself, and his suffering is spilling over. He does not need punishment; he needs help. That’s the message he is sending.” – Thich Nhat Hanh

WINDII Airglow Observations of Wave Superposition and the Possible Association with Historical “Bright Nights”

Gordon Shepherd and Young-Min Cho recently submitted to Geophysical Research Letters a paper entitled “WINDII Airglow Observations of Wave Superposition and the Possible Association with Historical ‘Bright Nights’” which appeared on July 4th. Bright nights is the name given to those nights which should be dark, with no moon, and yet they are bright enough to allow observers to see their surroundings, or distant objects, or even read a newspaper. These have been reported from Roman times, for example by Pliny the Elder, who wrote, “The phenomenon commonly called “nocturnal sun”, i.e., a light emanating from the sky during the night, has been seen during the consulate of C. Caecilius and Cn. Papirius (~ 113 BCE), and many other times, giving an appearance of day during the night”. These reports continue in the European literature up until World War I, but afterwards fade away as the use of artificial light increases. Limited scientific observations began then, during which the name “bright nights” was applied, but there has never been an explanation of their origin.

The Wind Imaging Interferometer (WINDII) was launched in 1991 and it was seen immediately that the 557.7 nm atomic oxygen airglow was extremely variable, from place to place and one night to the next. This “airglow” emission is caused by the photo-dissociation of O2 in the daytime by solar ultraviolet radiation, followed by the recombination of the atomic oxygen during which the energy released emerges as green line photons. Some years later it was recognized that there might be a relation to “bright nights”, but without any obvious explanation of the mechanism. However, in the meantime there were WINDII studies of the longitudinal wind and airglow intensity variations, leading to a resolution of longitudinal waves 1, 2, 3 and 4, where the number indicates the number of waves around the Earth at a given latitude. Early this year Young-Min discovered that from time to time the peaks in these propagating waves could coincide, causing a large peak in intensity at a given longitude, and that this could explain the bright nights. WINDII observed such events 7% of the time for the whole Earth, but at a given limited location the probability would be only 10% of this, and allowing for full moon periods means that the bright nights would be observed only once per year. The fact that they were reported so frequently centuries ago can be accounted for by the fact that the whole population was living with dark nights and so when a bright night occurred anywhere over land, it would be reported.

Geophysical Research Letters identified this as an article of public interest and created a press release that has kept Gordon busy on the phone and in e-mails since then. The story was picked up by the New York Times, the CBC, and from them by The Guardian, as well as in many other places such as the India Times and Korean newspapers. He also heard from individuals, one in particular who told the story told to him by his grandfather, who was playing football with his friends after dinner in 1908. They played and played and when the grandfather got home he was chastised by his parents for staying up until midnight. He protested that he didn’t know it was midnight as he didn’t have a watch, and it was still light. This experience stayed with him for decades as he didn’t tell it to his grandson (the writer) until much later. Gordon confirmed with the grandson that it was almost certainly a bright night.

The Guardian article can be found here.

The article includes a beautiful photo of the sky (see featured image) at night taken from the Grasslands National Park in Saskatchewan, near where Gordon was born – but it is not a bright night. The whole experience has been a surprise to the authors and a bit of a puzzle as to why there is such public interest. Probably it is the historical part, which has a human content, and the fact that bright nights are no longer being seen (at least not reported) owing to the environment change of artificial lights. Like some animal species, perhaps they have gone forever, for the public.
