What is the aim of TARDIS?

Why should we send dry aquatic invertebrates into space, an environment that certainly is not normal for these animals? There are many answers to this question. One would be: to see if these animals, as the first ever, are able to cope with the extremely dry conditions of deep vacuum and the harmful solar and galactic radiation up there. In the past, several biologists have suggested that tardigrades may be one of the few animals that have a chance to come back alive after a trip in real space. Finally we will be able to find out if this is true.

At a more mechanistic biological level, exposure of organisms to space conditions will reveal how living cells react to the potentially very stressful impact of space parameters. And organisms that can handle the damaging space parameters will be important sources of knowledge for how to generate the space ecosystems that will be necessary for the more permanent human establishments in space that is envisaged today.

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.

Once on the ground again, these samples will be analysed for survival and reproductive potential, and for damage on DNA.

Tardigrades are back on Earth!

This morning, at 9:58 CEST (Central European Summer Time), the FOTON-M3 capsule carrying the TARDIS hardware landed as expected in Kazakhstan, near the Russian border. Apparently, everything went as planned, and I hope this goes also for the TARDIS. More about this latest news from ESA can be read at http://www.esa.int/esaCP/SEMFVO6H07F_index_0.html. The launch of the rocket carrying the FOTON capsule can now also be viewed at http://www.esa.int/esaHS/SEMVIOK5P6F_research_0.html.

View the satellite carrying TARDIS on the web!

Today I learned that the position of the FOTON-M3 satellite can actually be viewed in real time.
So if you happens to be at a location where it passes during the night, and if the sky is clear, don't miss the opportunity to see the satellite carrying the first tardinauts in history!

Tardigrades in orbit!

Last Friday, the FOTON-M3 satelite was successfully sent into orbit, and the Biopan-6 platform was opened, exposing tardigrades of the TARDIS experiment to open space. The satelite will now orbit the earth at a 90 min. interval until 26 September, when the FOTON capsule hopefully lands in an area near the Kazakhstan-Russian border. Read more about the FOTON-M3 mission at http://www.esa.int/esaCP/SEMQDB13J6F_index_0.html
While waiting for the tardigrades to complete their trip in space, you may want to find out some more about tardigrades. Here are some great sites on the web:

Tardigrade samples delivered to ESA for integration into Biopan-6!

Yesterday, 6 September, the TARDIS hardware with samples were delivered to the European Space Research and Technology Centre (ESTEC) south of Amsterdam. Integration of all scientific hardware are now taking place.
One week from now, on 14 September, the first tardigrades in history will experience real space conditions.
