Man and computer

Man is the best computer we can put aboard a spacecraft … and the only one that can be mass produced with unskilled labor.

The shuttle as a peer

Kat Hanaford at Gizmodo (http://gizmodo.com/people/KatHannaford/posts/) reports a photo taken by a skydiver during the last space shuttle launch (full article at http://gizmodo.com/5569462/space-shuttle-launch-aims-for-the-sun-seen-by-sky+divers, twitter post at http://twitter.com/titleofmagazine/statuses/16724087066, post at http://twitter.com/GreatDismal/statuses/16725509751, original post at http://io9.com/5569200/a-space-shuttle-launch-as-seen-by-sky+divers).

This is the photo.

Only one comment: WOW!

Space X Falcon 9 enters earth orbit and opens to new era

As reported by many sources, and among them Nell GreenfieldBoyce at NPR (http://www.npr.org/templates/story/story.php?storyId=4494969), Noah Robischon at Fast Company (http://www.fastcompany.com/user/142631) and Jason Paur at Wired (http://www.wired.com/autopia/author/jasonpaur/), privately  financed rocket Falcon 9 owned by Space X entered orbit at first launch (full articles at http://www.npr.org/templates/story/story.php?storyId=127487766&ft=1&f=1001, http://www.fastcompany.com/1656560/spacex-falcon-9-successfully-launched-into-orbit-video, http://www.wired.com/autopia/2010/06/space-x-goes-into-earth-orbit/).

I think that is a great breakthrough in space activities, that, if continued, will bring an overall efficiency in space travel.

Is not (only) the fact of succeding at first try, but is a matter of economy, because in a medium timeframe, I suppose the owner of Space X will try to reach the breakeven, demostrating that is possible to have space transportation at a reasonable rate.

I don’t think that this as a first outcome will lead to more tourists in space, but will surely bring more commercial payload up ther in the sky, enabling also medium sized countries to have access to near space.

GPS failure and how much we rely on technology

Dan Elliott of Associated Press reported yesterday a news on a problem “[…] that rendered as many as 10,000 U.S. military GPS receivers useless for days is a warning to safeguard a system that enemies would love to disrupt, a defense expert says.  The Air Force has not said how many weapons, planes or other systems were affected or whether any were in use in Iraq or Afghanistan. But the problem, blamed on incompatible software, highlights the military’s reliance on the Global Positioning System and the need to protect technology that has become essential for protecting troops, tracking vehicles and targeting weapons[…]” (full article at http://www.google.com/hostednews/ap/article/ALeqM5gp4YJHFW1EXEJiT8apgRFxg7dXwQD9G2DH680).

Greg Grant at Defense Tech commented on this remebering that “[…] 

Yet, earlier this year, Colin Clark at companion site DOD Buzz, reported on public comments by Air Force chief Gen. Norton Schwartz, where he said “GPS signals are particularly vulnerable in time of war since enemies know of the reliance U.S. forces place on its highly accurate signal.” Schwartz said the military must find alternatives to GPS when operating in denied environments because of the system’s vulnerabilities. […]”.

This could make sense, because is not the first time that someone has access to military satellites at different extent (remember talibans intercepting videos from UAV in Afghanistan or brasilian hackers accessing Navy’s satellites with home made dishes).

On the other side, everyone knows (and recent experiments such as the Unmanned X37B prove this) that space is in a way or another the theater to govern in order to obtain a strategic advantage.

What makes me think is how much we are relying on technology for our defense and civilian uses.

Within the years we have shifted from tech as a commodity to tech as a vital need and this is a problem we are not thinking to solve, neither in part neither in a whole.

A system like GPS should be safeguarded as something vital for all mankind and not be seen as a military target.

Space to park

Space is big; Space is dark; It’s hard to find; A place to park.
