It looks like things are really beginning to develop for the space tourism era. European rocket manufacturer Astrium has announced plans to develop the next generation of small space planes capable of sending 5 people into space. This design is different from the rest as it will take-off and land conventionally and will use jets for atmospheric flight but blast into space with a powerful oxygen-methane rocket. The promo video is also pretty exciting, documenting the two hour flight by means of a simulation…

Daily Roundup: Universe Today Article

Just the one article this time for the Universe Today. Todays article covers a recent US satellite mission carrying out some cool experiments in space. This orbiting mini-lab is carrying out tests on a new nanotech sensor that is sensitive to poisons in air (useful for spaceships, protecting astronauts), and possibly even more interesting, experiments on a new electrochromic film that could be wrapped around spaceships to keep them warm or cool them down. The wonders never cease…

Snippet: Space Debris is Becoming a Serious Problem, but Google Earth is Watching

Space junk as plotted in the Google Earth software.

Every time a rocket launches, a spaceship orbits, an astronaut drops some trash or the US blows up a satellite, debris is created. Space debris (a.k.a. space junk) is a nasty side-effect of our push into space, but it isn’t a recent phenomenon. Even the early Gemini missions in the sixties did it, as does the ultra-efficient International Space Station – bits of spacesuits, cameras, nuts, bolts and tools are accidentally (and deliberately) dropped into the vacuum. But it’s only a bit of litter right? Wrong. That’s a hyper-velocity rifle shot, and it’s coming to a spaceship very soon, if we don’t take action now…

A Possible Answer to Flyby Anomalies

Strange things are happening to our robotic space explorers. Also known as the “Pioneer effect” (the unexpected and sudden alterations to Pioneer 10 and Pioneer 11 trajectories measured as they continue their journey into the outer solar system), similar anomalies are being seen in flybys by modern space probes. Earth flybys by Galileo, Rosetta, NEAR and Cassini have all experienced a sudden boost in speed. After cancelling out all possible explanations, including leakage of fuel and velocity measurement error, a new study suggests the answer may lie in a bizarre characteristic of universal physics… [more]
