18.01.2022 The mechanisms of nature captivate us as a consequence of our awareness... From a spiral galaxy’s swirls, the water twisting down the sink... Here’s ice crystals growing in seconds, ... Beautiful.

14.01.2022 Here is a first colour pic from the new new lander, of the Martian tundra, it’s a short drive to the dry river delta. The mineral colours are amazing...

13.01.2022 Looking down from the ‘Sky Crane’ rocket powered decent vehicle, gently placing the rover on the surface...

08.01.2022 So from what I can make out, Perseverance is about one kilometre from where they wanted to land. Not bad at all!

07.01.2022 A Big well done to Lee McClenaghan for her Best Actor award in the Series Under the Milky Way.... And thanks for the mention Lee... it was fun working with you all on the show. Cam. Scroll to 6 minutes 30 seconds for the award bit....

07.01.2022 We’re down! Astonishing drone tech, since with a 14 minute latency of communication from Earth to Mars, everything on the craft is autonomous... you give a command and quarter of an hour later you see if it worked. We’ll it all going.... Now the search for signs of life can begin, since this is the primary goal of this mission, having landed in an old river delta the rover will scrape and drill for fossilised microbes or even living ones if the soil will protect any micro...bes from the unfiltered sunlight that bombards the surface. High UV radiation would break up any DNA of any life so if anything is to be found it will most likely be in the moist or even frozen (permafrost) just below the surface... The is water on Mars but is seems to have a very high mineral concentration even salty like thick ‘Brine’... Water has been photographed oozing down the sides of some craters on Mars, note also that Mars surface temperatures in the right conditions can get up to 20 degrees C above zero, possibly higher. Also this mission has the first ‘Helicopter’ to fly on another world, from us. This drone, nearly 2kg, will fly a planned 6 times and possibly more to acquire flight data for other future rotor craft surveys of the Red Planet.. Exciting days ahead! Cam, ADU...

01.01.2022 Here’s selection of GoPro videos showing some stages of landing from on board the Mars Perseverance Rover... great stuff! And yes Thanderbirds are go! https://m.youtube.com/watch?v=4czjS9h4Fpg

01.01.2022 Distintos hemisferios, distinta forma: misma Luna Este fenómeno ocurre debido a que, físicamente, el punto de vista del hemisferio nort...e está "al revés" en comparación con el del sur. Por ello, depende donde nos encontramos, podemos ver las fases de la luna invertidas, e incluso, cerca del Ecuador, la luna creciente se ve como una cara sonriente. Video.- James O'Donoghue
