Above: ESA’s Mars Express has used radar signals bounced through underground layers of ice to identify a pond of water buried below the surface. This image shows an example radar profile for one of 29 orbits over the 200 x 200 km study region in the south polar region of Mars. The bright horizontal feature at the top corresponds to the icy surface of Mars. Layers of the south polar layered deposits – layers of ice and dust – are seen to a depth of about 1.5 km. Below is a base layer that in some areas is even much brighter than the surface reflections, while in other places is rather diffuse. The brightest reflections from the base layer – close to the centre of this image – are centred around 193°E/81°S in all intersecting orbits, outlining a well-defined, 20 km wide subsurface anomaly that is interpreted as a pond of liquid water.

The September-October issue of Free Astronomy Magazine has been up for a few weeks now and I hope you were already aware of that from the CNY Observers post about the same.
I’m also pleased to report a promotion from contributing translator to contributing author this month with the publication of the cover story “A Possible Subglacial Lake On Mars.” For the local record, a PDF of the article (with cover and edition TOC) is available for direct download at 5FAM2018_dgallis.pdf and I can now say that my work has been published in over three languages (four, to be exact, including English, Spanish, French, and Italian).
Please download, read, and pass along. Also, check out the many back issues at www.astropublishing.com

I am very pleased to mark my new editing contributions to the English-language version of Free Astronomy Magazine, starting with the current May-June 2018 issue. This new role was made possible by Michele Ferrara, Editor-in-Chief of the free and multi-language astronomy magazine that I have been very happily promoting on the CNYO site for several years now – and that I now get to promote here and on the CNYO site with my NASA Solar System Ambassador hat on. A combination of space agency publications (all the heavy hitters – NASA, ESA, ESO, ALMA, and Keck, among others) and original content, FAM has been a wonderful resource for those wanting to take a step beyond observation and into hard science and the many missions that make cutting-edge astronomy and astrophysics possible. It’s not only convenient to have a number of significant articles combined into a single magazine, but the inclusion of informative images and a great layout makes the download and read a no-brainer.
The process started in early April of figuring out what it meant to be providing a bit of translating and editing skills for both the text and the scientific content – that it, it not only has to be correct, you have to make sure it’s right as well (let that sink in!). And the timing could not have been better (although that wasn’t known until later in April).
Finally, it’s a wonderful thing to be able to combine science outreach (which I very much enjoy) with an established brand that is doing more than its share to make astronomy and space science accessible to a considerable part of the global population (we’re talking bimonthly magazines translated into English, Spanish, French, Italian, and Portuguese, with requests for additional translations into other languages scrolling on the main page).
