Sound familiar Doctor Who fans?

Tardigraded are these cute little chubby guys.


Why are they awesome? Besides having the same name as the Doctor’s means of travel…

Because they can survive in space unprotected. Yep, they can make it through temperatures just above absolute zero and in a complete vacuum.


Also known as water bears or moss piglets, these jolly-looking creatures have been found to survive on the outside of spacecraft in the vacuum of space. They can survive in temperatures from just above absolute zero to well above the boiling point of water. Cosmic radiation, ultraviolet radiation from the sun and extreme dehydration neither killed them nor prevented them from procreating, as a 2008 experiment showed.

The TARDIS experiment consists of two sets of samples: one set exposed to both space vacuum and solar radiation, and another set exposed to space vacuum only. All tardigrade specimens included in the study are in a dry, anhydrobiotic state. Species included are: Richtersius coronifer, Milnesium tardigradum, Echiniscus testudo, Ramazzottius oberhaeuseri. These are all known to be very tolerant to desiccation.

MONDAY, SEPTEMBER 29, 2008 – Space tardigrades stood the test!

 At last, the first results from the TARDIS experiment have been published! Thank you all for waiting patiently during the analysing and publishing process! Many of you have probably read already about the results in news media, and I apologize for being so late with updating my blog. The main reason has been a very heavy work load from answering questions from media all over the world. Fun but time consuming.

OK back to the Doctor. Here is the first official flight of the Tardis.
