This post is a collaboration with my good friend Bob Wegner, a professional musician, amateur astronomer, and genuinely good person. With the New Horizons spacecraft passing Ultima Thule on New Year’s eve 2019, Bob and I noticed that Queen guitarist and astronomer Brian May was on hand for the live event, playing a newly-written song to mark the event. Bob and I often talk about astronomy, as I’m always interested in his perspective as an enthusiast, while he’s equally interested in my opinion as a professional. We decided to take this event and write about it from two perspectives. For...
It wasn’t long after the discovery of exo-solar planets that scientists sent up spacecraft to look for them. The Kepler Space Telescope (KST) was NASA’s first planet finder, which has been exceeding expectations since 2009. It likely won’t get to continue on that road, as it is nearing the end of it’s life. At the same time, the Transiting Exoplanet Survey Satellite (TESS) is just starting to open it’s eyes. Today we say goodbye to one great planet hunter and hello to another. KST is part of NASA’s early 2000s spacecraft approvals that saw relatively inexpensive missions pushed forward...
On the golden record that accompanies the Voyager spacecraft, there is a map showing the location of Earth. It’s not a road map that you might pull out when navigating a city, but a 3D map showing the location of a star, the Sun, in a populous galaxy. But just how would this map work? And more importantly, what are the map markers? If you notice the lines at the bottom left of the golden record image, they all intersect at a common center point. This is the Sun, and the lines extend out showing relative distances to the nearest...
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,...
Dark matter could be almost anything. With little data other than how much total dark matter mass exists, we can’t decode much about what individual chunks of dark matter might be made of. I’ve talked before about Massive Compact Halo Objects (MACHOs) and Weakly Interacting Massive Particles (WIMPs), but these are just two possibilities. Other theorists have talked about Modified Newtonian Gravity (MNG), where gravity may work differently on the grand scale than it does on our small Earth scales. Or perhaps it’s something I haven’t seen before. Maybe what we call dark matter is just a large population of ancient black holes....
On the heels of my last review, I watched another movie with a space-documentary theme. Though it started out with the human perspective from space, it progressed into so much more. This is the TVO documentary called Planetary. It began with Apollo. Humanity broke the bonds of our world and set foot on another heavenly body. For the first time, we could look back and see the world as it truly is. One of my favourite quotes from the movie came up early, though I’m paraphrasing: We are the Earth, and the Earth is all of us. Seeing the Earth...
I am a big fan of John Oliver and his HBO show ‘Last Week Tonight.’ Last night the show covered a topic near and dear to me, the publication of science and how it is communicated to the layperson. He raises very important points about how scientists are motivated to produce exciting new research for grants and tenure, rather than replicating existing studies to prove or disprove them. He also talks about how science is portrayed in the media, and how studies are interpreted without context or fine details. We need science communicators. People who are scientifically literate and can communicate complex...
On July 4th, for about an hour and twenty minutes, my heart stopped. This was the amount of time that New Horizons was quiet. No contact, no data, nothing but the lonely black of space. In this time, the craft did what it was programmed to do. It transferred control to its backup computer, which told the main computer to enter safe mode and suspend all non-essential functions. Then the backup computer attempted to re-establish contact with Earth, 5 Billion Kilometres away. Contact has been re-established with the craft and its backup computer has been transmitting telemetry data back to mission...
I was downtown Toronto this morning, dressed in a suit and holding my umbrella to stay dry and navigate the city streets as they were soaked with rain. I was headed to the CBC building on John street to do an interview about the SpaceX CRS-7 mission that would launch an hour later. This would be a very important mission, the seventh of twelve ISS resupply missions contracted by NASA. It was also the third attempt at a secondary goal – landing the first stage launch vehicle, the Falcon 9 rocket, upright on an ocean platform, a feat that had...
This incredible video was just released by the National Space Society as the New Horizons team is primed to receive the first wave of data from the distant Pluto system. It feels more like a movie trailer, except that it is 100% true. I was left speechless by this amazing video and you will be too. The mission comes to a head on July 14th with the close flyby of Pluto and its five moons, though it’s possible there will be more moons discovered during the flyby.
