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...
As is the case with any final approach to a new object, the early images, with their horrible resolution, pixelated appearance, and possibly false features due to processing, lead to significant speculation on what we will see as the craft approaches. It was the same a few months ago with Ceres. I personally love the blurry images. It’s a mystery waiting to be solved, and we see it unfold as we move ever closer to our destination. It also reminds me of the early days of the internet I grew up with, using a good old 28.8K modem and waiting 2...
The true story of why Pluto isn’t a planet goes back further than you would think. It has a lot to do with our understanding of science at the time, and a lot more to do with surprising luck. I made this video a couple of days ago for the Khan Academy Talent Search. I hope you enjoy it. It will be interesting as we move into better telescope technologies that allow us to see further into the depths of the solar system and the universe. What strange mysteries will we find?
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.

New Horizons is giving Earth the A-OK! All the systems look good and we are only 37.4 million kilometres away from Pluto. Yes that is far, but considering we usually see Pluto at a distance 200 times that, we are doing pretty well. The newest processed photos have come in from NASA and John’s Hopkins University, and they are starting to show a complex and mysterious surface chock-full of science goodies that make astronomers salivate like Pavlov’s dog when the bell rang. But image processing is a science in itself, and I wanted to show you the difference between a raw photo...
As we are approaching the New Horizons bypass of Pluto just over a month from now, there is a lot of focus on the Plutonian system, from its strange Moons to its enigmatic surface. As we wait for the first ever high resolution images of the surface of Pluto, we can look to Hubble data to give us our fix. The best image of Pluto taken up to today, by Hubble, is blurry and at best can lead us to speculation about what we are seeing. But Hubble, as always, produces valuable science, and has given new insights into the...
Today is a busy day in the world of astronomy and space news. The US Air Force has approved SpaceX for military launches, ending a ten year monopoly by Boeing and Lockheed-Martin. A black hole jet moving at nearly the speed of light is having traffic issues, resulting in knots of jet material rear-ending each other. An experiment in Quantum Mechanics has shown that reality simply doesn’t exist until we measure it. Finally, the Gemini planet imager has found a bright, disk-shaped ring of dust around the star HD 115600, which is being likened to the Kuiper Belt in the...
I feel this will be a recurring theme with my posts, especially for those who read my blog on a regular basis. I love Pluto and am fascinated by new horizons. Its like a kitten chasing a ball of yarn. But with so many new possibilities popping up with Pluto as the new horizons rendezvous draws near, its hard to contain my excitement at the prospects of great science. The latest photo taken from just under 100 Million Km distant, shows some surface features for the first time. The features are interpreted as broad surface features, some are brigt and...
The Dawn space craft has finally begun its science phase after settling into a 13,500 Km orbit around the dark dwarf planet Ceres. It took some manoeuvring to get it in the right spot, but now it has begun mapping the surface as it slowly orbits once every two weeks. A lovely mosaic image from the space craft is the latest jaw-dropping picture of the former asteroid. Like a great shot of the Lunar terminator, by seeing the shadows created by the light from the Sun, we can get a sense of depth of the heavy craters on the surface....
Tis the season, as they say. This year is a good one for space missions with the March arrival of the Dawn spacecraft at Ceres and the July fly-by of Pluto by new horizons. Dawn made history by being the first ever spacecraft to orbit a dwarf planet, and new horizons will provide the first ever pictures of the surface of Pluto in unprecedented detail. I can barely contain my excitement, after having watched the launch of New Horizons live on NASA TV in 2006. I thought about what life would be like in 2015 and what Pluto would look...
