Space Suit of the Week

31 05 2011

A quick note today on a very excellent blog series called Space Suit of the Week.  Its weekly contributions feature, unsurprisingly, space suits as they appear in art, culture and history.

While entries vary in style from edgy or morbid to fascinating and  fun, the posts carry readers on a romp through some of the most identifiable imagery in our collective psyche.  It’s quite awesome.

The series is actually a sub-part of the The Fox is Black blog, which is billed as an “art and design website that seeks to discover and share the most interesting, beautiful and inspiring parts of contemporary life.”  I’d say that space exploration definitely fits the bill. 

Check it out if you get a chance.

Dealing with space contamination

Planetary Protection, despite how it sounds, does not refer to a Bruce-Willis-style suicide mission to save Earth from an incoming asteroid.  However, it is one of those practical space exploration concerns that will only get more important with time.

So, what is planetary protection (PP)?

Think of it as the discipline of preventing the spread of interplanetary biological contamination, either from or to Earth, by astronauts, rovers, and anything else we might send between worlds.

For instance, what good is the search for life on another world if we actually deliver it there, (e.g., bacteria hitching a ride on the outside of a spacecraft) – or worse – if we accidentally contaminate the site and kill the life we’re looking for?

To this end, NASA scientists have been developing the LOCAD-PTS, which stands for Lab-on-a-Chip Application Development-Portable Test System.  Much like a Star Trek “tricorder,” the handheld device includes an electronic swab wand and onboard processor designed for the rapid testing of biological substances.  In just 15 minutes, an analysis can be performed and contamination results delivered to a waiting astronaut.

A number of field tests have been performed with the system so far, with many actually performed in space on the International Space Station to determine how biological material is transferred from Earth to space, and to monitor the spread of that material while there.  Samples were taken both inside and outside the station.  Beyond contamination on the exterior of spacecraft being transported to another world, in a closed environment the movement of biological material is also important to ensure astronaut health.

Even better here is the famed NASA technology “trickle-down” effect.  The LOCAD system as tested by NASA will also be highly useful on Earth.

Applications of the LOCAD procedures and technology include not only science on Earth, but also detecting lethal viral outbreaks and helping first responders during a potential biological attack.

With the forethought of technology programs like this, not only will all worlds involved be kept more pristine, but any data gathered will be that much more defensible.  Here’s hoping that before too much longer, the offspring of the LOCAD will get to see some action off-world.
