Lucky to be living in silence

We continue Olivier Delanoë’s triptych on Concordia life starting with the leaving of the last aircraft…  Early February the last plane leaves. It’s an emotional moment to see our colleagues leave. For the next nine months our group of 15 people will live together with no help of rescue in case of trouble. Safety is most important and health issues can have dramatic consequences. We are very aware of this fact as we watch the aircraft disappear over the horizon. Winter has begun and we are on our own. We are completely isolated from the world in an incredibly hostile environment where temperatures can drop to -80°C. Life outside the base is...

The kingdom of light is about to end<...

Last Sunday the Sun disappeared below the Antarctic horizon not to return for over three months. The crew at Concordia research station will live and work under artificial light in complete isolation. Antonio Litterio describes the feelings of fear and amazement and suggests you listen to “Wild Side” by Italian musician Roberto Cacciapaglia as you read this entry. This unofficial video of the song was suggested by Roberto himself as a suitable version to play while reading: Antarctica continues to change as it enters a new phase and the kingdoms that make up this immense territory will follow. The kingdom of light is about to end. The midday sun is now  afraid...

Concordia Wonders

ESA-sponsored medical doctor Vangelis Kaimakamis continues his blog entry on science and celebrations and answers some reader comments: I would like to begin this post by  thanking you all for the continuous support to our mission either by reading or liking this blog or by leaving your comments to posts. Your encouraging words are an inspiration for us all! To answer some questions from previous comments, we use the refrigerators to keep products inside the main building frozen, as the temperature in the base is usually between +21 and +23 degrees Celsius, so there is a need keep some food cool! When we need to store material such as biological samples or...

Satellites over Concordia

Received from Alex: The ‘comet’ that appears is actually an Iridium satellite flare, which shoots across the milky way, which is surrounded by Aurora Australis – Southern Lights. Concordia Station, Antarctica

Teardrop from Heaven: Aurora Australis

We may have been the last folk to see the Aurora in Antarctica, but when it came, it was unforgettable. Incredible displays of coloured light, termed Aurora, are produced by collisions, when electrically charged particles travelling from the sun impact with charged particles in the atmosphere, as they enter the atmosphere.  Fluctuations in Sunspot activity create a solar wind – bringing the particle to Earth. Aurora can be different colours – ranging from pink to red to green to blue.  In fact, the different colours are caused by the involvement of different gas particles, and depend on their altitude of impact. Aurora occur in the Northern (Aurora Borealis) and Southern Hemispheres (Aurora...
