Imagine that you have just set up camp on Mars. Everything is up and running. You and your team have not only survived the journey from Earth, you’ve also made it through fiery re-entry and landed within a metre of your planned location. Success! So you crack open a miniature bottle of vintage whisky bottled in the year 2000 and share a sip with your companions. You want to tell the world, you want to check in with your family to say that you are “OK”.
It would be very poor if you were restricted to relaying a message though mission controllers. Simply “phoning home” for a chat wouldn’t be possible (the lag time between sentences would be at least 16 minutes). Could there be a way of sending emails? Possibly; voice messages will be fine too. But could our explorers set up a website or some “Mars blog” to document their travels? This could obviously be done remotely, with a terrestrial website, but there are strong arguments for a distributed Internet service on the Red Planet too. Can a “MarsNet” or “RedNet” be integrated with Earth’s Internet, establishing an “Interplanetary Internet”?

It’s been a while since I last posted as I’ve been flying from the US to the UK and have only just gotten my office up and running. That’s not to say I haven’t been writing. On the Universe Today, I’ve posted quite a few articles ranging from quite an elaborate April Fools story (but not quite as elaborate as Virgin and Google’s Virgle prank), to a black hole hiding in the middle of Omega Centauri, to rocks rolling around on Mars… here’s a round up of the most interesting…

This week has been an exciting week for astronomers. The largest explosion ever seen in the Universe was observed on Wednesday. This gamma ray burst, produced when a star collapses in on itself to create a black hole, is a record breaker. Not only is it the biggest explosion mankind has seen since records began, it is also the furthest and oldest “thing” we have ever observed…

It doesn’t get much better than this. A robotic orbiter snaps a photo hundreds of miles above the surface of an alien planet, capturing a geological event as it happens. Yes, we’ve seen Io’s immense volcanoes erupt, and we’ve seen huge storms rage on Jupiter, but often these large-scale planetary events are too massive for us to put into context and so we file them under “astronomy”. But, when we see an event like an avalanche on Mars, we can relate it with events on Earth, we have a “feel” for what this means. Suddenly an avalanche on Mars holds a special meaning to us; we instantly have a connection with other planets in our Solar System.
And now for the question… what caused the four near-simultaneous avalanches recently observed by the Mars Reconnaissance Orbiter?

There has been much debate surrounding observations by the artificial satellites orbiting Mars, but with one discovery, the debate was… non-debatable. Liquid water was flowing (albeit quickly) across the Martian surface intermittently, creating river-like channels flowing down crater sides. But that was until a group of University of Arizona scientists tackled the situation. To their surprise it wasn’t water that was flowing, it was something entirely different…

We all know that space can be a dangerous place. Many safety measures are put in place by space agency scientists so astronaut’s lives are protected and mission success can be assured. Generally, some degree of certainty can be insured in near Earth orbit, protecting astronauts onboard the International Space Station and Shuttle missions, as most activities go on within the Earth’s protective magnetosphere. But in the future, when we establish a colony on the Moon and Mars, how will human life be protected from the ravages of solar radiation? In the case of Mars, this will be of special interest as should something go wrong, colonists will be by themselves…
