The Return of Space: Star Citizen & X-Rebirth

I loved space-based games when I was a teenager.  Titles such as Wing Commander, Privateer and Tie Fighter dominated my down time and proved to be among the most enjoyable gaming moments of my life.  In recent years, the X-series space sim games , which captured the ‘Elite‘ gestalt, have been my only connection to that past, and in all honesty they’re pretty good.  More recent versions, such as X3 – Terran Conflict, have been beginning to hit a sweet spot between insane trading, owning and controlling spaceships and space factories of all sizes, and decent combat.

Well, I’m happy to announce that the future is looking pretty rosy, and it’s all on PC.  The creators of the X-series, Deep Silver, will be releasing either late this year or next year X-Rebirth, which promises to turn space into a living environment, bringing science-fiction dreams that little bit closer to the PC. Following the release of X-Rebirth, is Star Citizen, an online/offline MMO in the vein of Wing Commander and Privateer that brings what I see as Battlestar Galactica in an alternate form to the people with graphics and ideas that promise to empty wallets in seconds.

Space sims have had a bad name for a while now with mainstream developers continuing to steer clear of a genre that is beloved by so many, for reasons that are completely unknown to me.  So, it’s good to see smaller companies and startups trucking it up to fill the void and shame the big companies who have become lost in console 1st person and 3rd person shooters, unwilling to break out and take a risk.

Detail and flexibility are the new buzz word for space sims on PC.  We want to see and do everything, and developers are doing their best to deliver that.  Outer space is about to become a whole lot more exciting.

Teenage girl shot in head by Taliban in response to campaign for women’s right to education

In Pakistan, a 14 year-old girl, Malala Yousafzai, was shot in the head by Taliban militants in response to her promotion of secularism, the BBC reports.

The girl, who with her father have promoted the education of girls and women in Afghanistan, wrote a diary for the BBC in 2009 when she was 11.

Videos of Malali Yousafzai can be found below.

(R-Bar – Radial Bar – is an imaginary line connecting station to the center of the Earth)
• Height adjust burns start adjusting altitude higher toward station
• COTS Ultra-high Frequency Communication Unit (CUCU) and on-board UHF communication system between Dragon and ISS is configured
• Height adjust burn: Dragon begins burns that bring it within 2.5 km of station (go/no-go)
• Dragon receives and sends information from/to the CUCU unit on station
• Height adjust burn brings Dragon 1.2 km from station (go/no-go)
• Height adjust burn carries Dragon into the station’s approach ellipsoid (go/no-go)
• Dragon holds at 250 meters (go/no-go) for confirmation of proximity sensors targeting acquisition
• Dragon begins R-Bar Approach
• Dragon holds at 30 meters (go/no-go)
• Dragon holds at capture point, 10 meters below the station (go/no-go)
• Crew captures Dragon using the station’s robotic arm (SSRMS)
• Dragon is attached to the station

Mars bricks made from bugs

In what is a completely novel twist on overcoming the habitation problems of humans going to Mars, NASA has begun designing microbes to assist in the development of bricks, fuel and plastics, Andy Coghlan from New Scientist reports.

With weight a premium in space travel, carrying large quantities of building materials is expensive, and energetically inefficient.  But by bioengineering bugs like Anabaena, which consume CO2 and nitrogen, to excrete greater levels of sugar, resources such as fuel, oil and plastics can be, in theory at least, developed on Mars.  Similarly,  Sporosarcina pasteuri, a urea feeding bacteria, excretes ammonia that can be used to assist in the development of calcium carbonate, to cement soil particles together and construct bricks.  Experiments have already proven the validity of this particular concept.

Despite issues of unleashing micoorganisms onto another planet, the idea of using bugs to develop fuel and materials on another planet promises to help make that NASA trip to Mars that little bit lighter, and also that little bit more possible.

Two black holes instead of one

Globular cluster M22 (image source: NASA JPL)

The Australian Geographic reports that scientists have observed two black holes  sharing the core  of a globular cluster together.  The two black holes, each around 10 to 20 times the size of our Sun, appear locked in a dance together, with neither occupying the very centre as expected – a first for a globular cluster.

Locating black holes is not an easy process, as other stars are needed nearby to observe the effects of the black hole in action.  Scientist James Millar-Jones, from Curtain University Australia, thinks there is probably more black holes in the cluster, stating

“M22 may contain as many as 100 black holes but we can’t detect them unless they’re actively feeding on nearby stars”
