#PPOD: On June 25, NASA’s #JWST turned to famed ringed world #Saturn for its first near-infrared observations of the planet. The initial imagery from JWST's NIRCam (Near-Infrared Camera) is already fascinating researchers. Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright. Credit: NASA/ESA/CSA/STScI/Andrea Luck
If you love #scifi, #space, #spaceexploration etc then #ACityOnMars is a fantastic read on the harsh realities of space settlement (and what we don’t know about it). Check it out!
Some #murals outside the #ISRO#museum or Vikram Sarabhai #Space Exhibition Center. More than the space stuff, enjoyed the #mural(s) painted on the walls.
Happy to say that The Battle of Victoria Crater Part I and Part II are now online! The novella takes place in the desolate Martian frontier of Victoriaville, a brave community of settlers faces relentless threats from mercenary bandits working for a powerful Earth corporation, WTO. At the same time, life as a Martian teenager comes with some interesting challenges. This time, the light at the end of the tunnel comes with grim news – not only are the bad guys on their way, so are desperate refugees and a monstrous dust storm. Pete and Martin risk everything to rescue the plucky pioneers from certain doom. Martin learns in the grinding dust and darkness that victory is something you win, one step at a time.
ETH Zurich is developing a new radiation-robust microcontroller that uses the triple lock-step method to validate its own computational results. The basis for this is a RISC-V based design.
Lockstep is nothing completely new in the RISC-V area either, but the focus on energy consumption is interesting. Perfect for satellites!
