Rosetta’s Final Mission

Tomorrow, one way or another, the ESA’s Rosetta mission is coming to an end.  In a final maneuver, the craft will attempt to land on the surface of the comet, following in the footsteps of the Philae lander, though hopefully with more success. The video shows the final orbit plan, and really highlights how amazing mission scientists are to be able to plan a landing site when the comet is rotating so quickly, relative to the craft’s motion. You can follow the link to watch the live broadcast of the event here.  The mission will end around 7:20am EST tomorrow,...

The Space X Martian Trailer

In the past year or so it’s been interesting to see space agencies and companies produce movie-type trailers for scientific expeditions.  The technology is there, and it is a proven way to inspire the general public.  It also creates an opportunity to create some of the amazing science being done, even if it’s just a small taste. Space X has been candid about wanting to colonize Mars, and yesterday they released a trailer to give some inspiration to all of us. It shows a system that utilizes their nearly-established system of landing and reusing rockets, as well as refueling in...

Why We All Use the Same Units

Here is a map of the nations of the world that use the two systems of measurement.  Metric shown in blue and imperial shown in red. While it’s not always good to go with the crowd, there is a reason why more nations use the metric system. An often-cited passage from the book Wild Thing by Josh Bazell: “In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount...

Juno July

As Canadians start up Canada day celebrations and Americans get ready for their independence day, the world of space exploration holds its breath and hopes for a good result.  On July 4th, the Juno spacecraft will arrive at Jupiter after a five year long journey.  NASA continued its recent theme of producing movie-trailer-like videos to promote the mission. Although I love the imagery and the design of the trailer, it feels cheesy to me.  Maybe it’s because I find movie trailers cheesy in general, and this is trying to appeal to the general public.  Though regardless of how I feel,...

Europa Chemistry

I always get giddy when talking about Europa, as many astronomers do.  It’s one of the most fascinating places in our solar system when it comes to the search for life.  It has lots of water, likely contained in a subsurface ocean.  It’s heated though a gravitational tug of war with Jupiter and the other Galilean moons.  And, as of recently, it has a chemical production system that matches Earth’s. I wonder what goes on beneath the thick ice of Europa.  Is there an ecosystem filled with alien life down there?  Life in Earth’s oceans feels very alien, but creatures from...

The Next Canadian Astronaut

This guy is everything you expect in an astronaut.  At least that was my first thought when I was looking at his biography.  David St. Jacques was one of only two candidates (along with Jeremy Hansen) chosen in the 2008 Canadian Astronaut draft, the third in our nation’s history. He has a degree in Engineering Physics, a Ph.D. in Astrophysics, and is a medical doctor.  And that’s just his formal education.  He’s an avid mountaineer, cyclist, skier, and sailor.  Not to mention his advanced certification as a scuba diver, his commercial pilot’s license, and his ability to converse in Russian, Spanish, and Japanese. And so...

Review: IMAX: A Beautiful Planet

I recently had the opportunity to watch a brand new IMAX feature, called A Beautiful Planet.  It features incredible views of the Earth from space, captured by astronauts aboard the International Space Station.  Most of the footage was taken during Expedition 42 on the ISS, starting with the arrival of Samantha Cristoforetti, Terry Virts, and Anton Shkaplerov aboard the Soyuz TMA-15M, and ending with their departure. Much of the film was focused on the views of Earth, the scenic diversity of life and land that can only be seen from space.  It was difficult to see the effects of humans during the day time,...

Falcon Flight to the Galaxy

In the APOD photo from May 14th, it is easy to imagine the rocket launching far away into the galactic disk.  Sadly the rocket can’t traverse the thousands of light years to reach the distant stars, and is restricted to orbiting the Earth. Another beautiful part of this image is the technique involved in producing it.  It required combining two exposures. The first, with low sensitivity to capture the orange rocket trail of the Falcon 9.  The second with high sensitivity and a longer exposure time to capture the faint light of the Milky Way galaxy beyond.  The result is...

New Kepler Planets Confirmed!

In a major announcement this week, researchers with the Kepler Space Telescope science team have confirmed the existence of 1,284 new planets that had originally been found by Kepler.  This is a huge leap in the number of confirmed planets, bringing the total to over 2,300. The previous science data collection done by Kepler was completed in 2013, so why is this new news? Well the exciting part is that these are confirmed planets.  Usually when Kepler detects a signal indicating a potential planet, it needs to be verified by using some of the larger ground-based telescopes.  Kepler is not immune...

Mercury Transit Now!

The Transit of Mercury is happening right now here on May 9th, 2016.  If you want to watch live, check out the NASA feeds from the Solar Dynamics Observatory. For the small size of Mercury, it makes a pretty stark contrast against the bright Sun, and is easy to see, even in a small telescope.  Of course, you need a solar filter.  Don’t look directly at the Sun without proper eye protection, you won’t see Mercury and you’ll damage your vision. I managed to snag a photo on my phone through a small telescope.  Please excuse the lack of quality...
