It sounds completely like science fiction, something out of a campy space thriller where the protagonist is a miner taking a daily shuttle to the Moon to mine all the precious metals that the Earth needs to sustain itself. But in real life, for a long time, it was thought that the Moon was a dead rock, completely useless to humanity except as the gravitational force to provide the amazing tides in the bay of Fundy. Today we know so much more about the Moon, and its value has (pun intended) skyrocketed. For one, the low gravity of the Moon...
Its no secret that Elon Musk wants to go to Mars, and if he keeps steering the ship of amazing work done by SpaceX, he will have full support. He has been candid about mistakes, honest about goals, and modest about successes. So with Mars on the horizon in the future, here are some tourism posters made by SpaceX. All images courtesy of SpaceX. They have such a retro 50s sci-fi feel, which I love. It’s making fun of all those old campy posters, but there is a decidedly romantic feel to them, especially for anyone who has dreamed of...
As the capsule separates from the first stage rocket, the second stage booster takes over and sends Dragon into orbit around the Earth to rendezvous with it’s target a few hours from now. At this point the mission is a complete success from NASA’s perspective, but to Elon Musk and the rest of the SpaceX team, the real challenge is just beginning. They have to land that first stage rocket on a 300 x 170 foot barge in the vast ocean, or risk losing millions of dollars in their investment. Here’s how it went. Okay not so well, but arguably...
About a year ago I had an idea for a music video. I wanted to take a concept in science and put it to music, making it funny, catchy, memorable, and educational. I wrote out the majority of the lyrics but left it alone for a few months, until I connected with the right friend. My good friend Bob Wegner is a very talented guitarist and audio engineer, and as we spoke about the idea he wanted to be the guy to record it. We spent an afternoon doing the vocals and guitars, and he cleaned it up and made...
When Canadian Astronaut Chris Hadfield was in space, on the International Space Station (ISS), he stayed there for six months, the standard length of stay for an astronaut. On the ISS, three of the six-person crew are replaced every three months. After returning to Earth, Hadfield could barely walk. He had lost bone density and muscle mass, his immune system weakened, cardiovascular functions slowed, and he produced less red blood cells. The lack of gravity is bad for humans, The longest a human being has ever been in space was Russian cosmonaut Valeri Polyakov, who was in space for a staggering...
Yesterday I posted some of my own photos of the Moon and Mars in conjunction from the night before. Last night I went out again knowing that there was another planetary conjunction in the works. The Moon was now with Venus. People on the internet and in person were asking me “Mars? I thought the Moon was near Venus,” and “Venus? I thought the Moon was near Mars.” It really speaks to the fact that most people don’t realize how quickly the sky changes from the point of view of an Earthbound observer. So what happened between the Mars-Moon and...
Every 29.5 days we see a new Moon, or rather we don’t see it, since it’s lost in the glare of the Sun. But a few days after the new moon, we can see it slowly move away from the Sun and become visible after sunset, with the thinnest crescent growing a bit larger each night. You may have heard that Mars and Venus also live in the Western sky after sunset, with Venus moving higher and Mars appearing to double back toward the Sun, soon to be lost in the glare of our home star. Last night I was...
With all the talk of the large geomagnetic storm of the past few days, it’s important to understand that other worlds have beautiful auroral activity as well. Being on Earth and seeing the gorgeous displays that result from our magnetic field protecting us from harmful solar radiation, the best views come from Earth. But there are several other places in our own solar system that have aurora. Jupiter has a massive magnetic field, and its gigantic aurora are visible here. Jupiter’s moon Ganymede is the only moon in the solar system that has auroral activity. Saturn has its own, discovered...
After feeling an electrical surge in the drilling instrument last month, the Curiosity rover has once again picked up and continued its journey toward mount Sharp in the Gale Crater. On Wednesday, the rover finished transporting recently drilled material from it’s robotic arm to instruments on the rover’s body, before driving 33 feet on Thursday. The short circuit occurred on February 28th, and since then the mission team has been running tests to ensure everything was okay before resuming operations. The short circuit was caused by the percussive function of the rock drill on the rover’s robotic arm, and as the...
I love to discuss Mars rovers. The thought of robots roaming around the empty red desert, doing science in pure form, unmasking the surprising history of our red neighbour, it’s exciting and it’s the frontier of discovery. The limits of science and engineering are pushed as we send complex machines to travel further than any human in history. But with such a marvellous feat, issues can arise, and when they do, the nearest mechanic is 55 Million Km away. On February 27th, during the transfer of a sample of dust from the rover’s drill to its instruments, the rover suffered...
