Our posters at EGU!

Our first poster on Wednesday evening was from the Mars Analogue mission run in Morocco by the Austrian Space Forum.  Ania Losiak had masterminded a mapping process for our science team which underpinned all the planning for the mission and became our main database of experimental results, as well as being an experiment in itself that we can compare what was planned to what actually happened, which we hope to be able to improve in future analogue missions.

Liquid water on Mars today?

Diedrich Moehlmann, DLR, set out to convince us that liquid water can and does temporarily exist between two surfaces such as two grains of rock in the upper surface of Mars today and to indicate where it may be found.

The puzzle for astrobiologists is that they know liquid water must have been plentiful in the past on Mars, but at present times we have only confirmed water ice and atmospheric water vapour. Water vapour can reach saturation in the current atmosphere of Mars, which makes it favourable for it to be bound to a surface. The Mars Phoenix lander found direct indication for liquid droplets on Mars.

Monday at EGU

Monday morning saw huge advance queues eagerly awaiting the 8am registration opening. Planetary sessions started about Mercury, though notably the first speaker had withdrawn to the new NASA policy of no conference travel expenses following sequestration. This is to be a theme of the conference, though in some cases other co-authors have managed to step in on behalf of absent colleagues.

The much anticipated event of the day was the MSL Curiosity press conference at 11am, with John Grotzinger and colleagues delivering the latest discoveries from this amazing mobile laboratory on Mars.

Meteorites at the Natural History Museum, Vienna

The Natural History Museum boasts the oldest meteorite collection in the world, with the first two pieces entering the collection in 1778. It pre-dates the study of meteoritics and is one of the largest collections.

This 300kg meteorite Knyahinya, greets you as you enter the room, from a witnessed fall in 1866 in the Ukraine Carpathians. For a long time this frgament was the largest known stony meteorite.

Fantastic informational displays and interactive "is this a meteorite?" stands keep it interesting for the family, for example with a magnifier you can move along over a whole range of different types of meteorite with the corresponding information appearing on screen as you move it.

EGU General Assembly 2013

The European Geosciences Union General Assembly takes place from 7-13th April 2013.  Over 11,000 attendees are registered at this largest meeting for geoscientists in Europe, I'm honoured to have my blog featured on their official blog roll.

I look forward to covering the Mars and lunar session, starting with the MSL press conference this morning at 11am (CET) together with a smattering of volcanology and geology over the week.
If you are here, don't forget to download the EGU app, which makes it much easier to browse the mammoth programme and flag up what you want to attend, as well as having a dedicated inbuilt Twitter feed tracking the hashtag #EGU2013.

If you want to take a breather at some point, I can highly recommend the Natural History Museum. Show your EGU2013 pass to get a discount (5 euro entry fee) and don't miss room five with the 900kg meteorite - see my next blog post! Amazing collection of meteorites including Mars and lunar samples.
