How do you fight fire in space? Experiments provide some answers
Updated: 2012-01-31 19:09:37
Improving fire-fighting techniques in space and getting a better understanding of fuel combustion here on Earth are the focus of a series of experiments on the International Space Station, led by a professor at the Jacobs School of Engineering at the University of California, San Diego. A first round of experiments ran from March 2009 to December 2011. A second round kicked off in January and is set to last a year or more.
Bright sparks redefine propulsion Space blog Bright sparks redefine propulsion CubeSats , like STRaND-1 are essential for the breakthrough of new technologies in the space industry . The relatively inexpensive CubeSat enables institutes and companies to test technologies and gain valuable flight heritage without risking millions or even billions of pounds of . investment STRaND-1, the joint project between SSTL and the Surrey Space Centre SSC is one of these exciting experimental satellites and it’s not only its smartphone that makes it exceptional . Engineers at the Surrey Space Centre have also developed a unique mass and power saving plasma propulsion system to fly on the satellite . This system will be the first propulsive technology to provide very precise attitude control and .

Confirming Kepler’s planet candidates is a crucial part of the process, because no matter how tantalizing a candidate appears to be, its existence needs to be verified. We have more than 60 confirmed Kepler planets and over 2300 candidates, many of which will eventually get confirmed, but it’s interesting to see that the mission’s latest [...]

Back in the days when I was studying Old Icelandic (this was a long time ago, well before Centauri Dreams), I took a bus out of Reykjavik for the short journey to Þingvellir, where the Icelandic parliament was established in the 10th Century. It was an unusually sunny day but that afternoon the storms rolled [...]
The methane/ethane cycle we see on Titan is reminiscent of the water cycle on Earth, which is what people are really talking about when they refer to this frigid place as vaguely ‘Earth-like’ — this is not exactly a temperate climate! But we have a long way to go in understanding just how the cycle [...]
How solar storms affect you Space blog How solar storms affect you We are currently experiencing the effects of a solar storm . Since Monday morning , high-energy particles have been hurtling towards Earth from the Sun . This is the result of a Coronal Mass Ejection CME a sudden burst of electromagnetic energy and particles released into space from the Sun’s atmosphere . This Youtube video shows a large solar eruption that occurred in June , : 2011 In space , CME particles can collide with crucial electronics onboard a satellite , disrupting its systems . This is of particular concern in a region centred over a point close to the Falkland Islands , known as the South Atlantic Anomaly , where the Earth’s inner radiation belt comes closer to our planet’s surface . Normally satellites
Imagine what we could do if we could attain speeds of 640 kilometers per second. That’s the velocity of a comet recently tracked just before passing across the face of the Sun and apparently disintegrating in the low solar corona. I’m just musing here, but it’s always fun to muse about such things. 640 kilometers [...]
NASA’s Innovative Advanced Concepts program has issued a second call for proposals, following the selection of its first round of Phase I concepts in 2011. NIAC (formerly the NASA Institute for Advanced Concepts) ran from 1998 to 2007 in the capable hands of Robert Cassanova, who is now external council chair for the new organization. [...]
What to say about an extrasolar ring system that has already had its four distinct rings named? Rochester, Sutherland, Campanas and Tololo are the Earth-bound sites where the unusual system was first detected and analyzed, and the international team of researchers involved thought them suitable monickers for the four rings thus far detected. The light [...]
DMCii captures Rio flooding image Space blog DMCii captures Rio flooding image DMCii has acquired an image of the recent flooding in Brazil . Torrential rains and a broken dam caused the Paraiba do Sul river to burst its banks close to the coastal town of Atafona , Rio de Janiero . The level of the River reached 10.9m , 3 metres higher than normal meaning over 4,000 people had to be evacuated from the immediate area . As reported by the Rio Times the nearby town of Três Vendas was so badly affected that it was patrolled by city guards to prevent looting and the power was cut to prevent short circuits . occurring Flooding of Paraiba do Sul river . Image from UK-DMC2 SSTL 2012, supplied by . DMCii This is one of many flooding incidents in south-east Brazil with total evacuation numbers now

As 2011 draws to a close, it’s time to reflect on my absenteeism from Astroengine. But it’s not my fault, I’ve been typing like a madman for these guys. But that’s enough excuses, 2012 promises to be a huge year for space, and if I get my time management skills back up to scratch, there [...]
: 2011 in review : IAC to STRaND-1 Space blog 2011 in review : IAC to STRaND-1 We hope you enjoyed the first half of our year in review yesterday , but there’s more to cover and it is the season for giving after all In October the SSTL-50, SSTL’s new microsatellite platform , landed at The International Astronomical Congress IAC in Cape Town , South Africa . The SSTL-50 is a highly cost-effective satellite design that can be built and launched in just 12 months . Its small size also means that two SSTL-50’s can fit facing each other in a space head module so double the amount of satellites can be launched in one go . It doesn’t just redefine cost effective space again but its dual-mode design also offers scientific missions state-of-the-art innovation with the piece of mind of SSTL’s
: 2011 in review : From UKSA to Kepler Space blog 2011 in review : From UKSA to Kepler In 2011 Europe has launched its first satellites into its future GNSS constellation , America has found Earth-like planet Kepler-22b while China has dominated space news , and Russia’s stricken Phobos-Grunt has brought the year to a close . Following the formation of the UK Space Agency in 2010, the UK has also had a busy year especially here at SSTL . We have seen important projects reach major milestones , celebrated anniversaries , and unveiled some very exciting new space technologies to the world . In February , the Disaster Monitoring Constellation celebrated its 10th birthday . This unique international collaboration was set up to gather and distribute images of disaster zones anywhere in the
