Remember a few months ago when excitement was high about seeing the surface of the dwarf planet Ceres for the first time with the Dawn spacecraft? Remember when the pictures were simple and blurry and looked more like a conspiracy theorist’s UFO pictures than another celestial body? Remember when I wrote about how cool it will be when we become the first humans in history, and the first form of life to ever see the surface of this object? The lead up to the Ceres encounter is well summed up in the NASA video from right before the encounter. I...
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...
Being 2015, there has been a lot of talk about the New Horizons spacecraft in the first month of the year, since it’s due to reach it’s rendezvous with the enigmatic dwarf planet in July. I remember watching the launch in 2006 while in university, and have been talking about it to audiences during my planetarium shows. I feel close to the mission, and being able to see it reach Pluto this year brings back the first feelings I ever had about discovering the universe as a child. So when the spacecraft woke up a few weeks ago, so did...
…and not the ‘dawn’ we refer to when watching a sunrise. Dawn is a NASA spacecraft that was launched in 2007 with the goal of exploring the asteroid belt by observing its largest and most interesting objects up close. The two largest asteroids, Vesta and Ceres, have been the largest mission goals of Dawn as it has journeyed through the belt. From July 2011 to September 2012, Dawn was in orbit around the 525 Km wide Vesta, snapping amazing photos and studying the giant in detail. Since it’s departure from Vesta in September 2012, the craft has been on route...
