    Reduced evolutionary constraint accompanies ongoing radiation in deep-sea #anglerfishes nature.com/articles/s41559-024

    "deep-sea #pelagic #anglerfishes evolved from a #benthic ancestor and quickly underwent rapid diversification... these results demonstrate that spectacular evolutionary radiations can unfold even within environments with few ecological resources and demanding physiological challenges."

  6. Tara Tomlinson et al. Permeability and porosity of ice. At #LPSC2023.

    Mushy zones in ice. How to nutrients and salts get formed and connected during ice Freetown?

    (Y'all know I'm all into this for #astrobiology. This sets #microhabitats scale in #DeepIce.)

    Modeled, and compared with lab grown sea ice.

    Abstract: hou.usra.edu/meetings/lpsc2023

  7. And now my thoughts on why this is so neat. That clathrate layer insulates. Changes thermal profile through crust.

    So now it's warmer more shallow. So there's MORE volume in the #DeepIce of #Titan that might be habitable.

    Maybe don't need to drill so deep to get to good habitats?

    Remember, much easier to land on Titan. We already 1 for 1 on that world!!!

    Here is link to Lauren's abstract: hou.usra.edu/meetings/lpsc2023

  8. Turns out a compressed gas cart is really handy for moving ice cores.

    Kicked out of a downstairs lab freezer, I'm using the freight elevator in the Science building to move to another lab freezer at Jet Propulsion Laboratory.

    One of these is a section of firn ice from GISP2.

    What am I gonna do with these?
    Wait and see......

  9. Here is a 30-minute detailed presentation/short course on the astrobiology of icy microhabitats like we might find when we explore the Ocean Worlds (Europa, Enceladus, Titan, etc.)

    This was part of a Keck Institute of Space Studies (KISS) workshop where we gathered some researchers to try to figure out the technical challenges of targeting microhabitats during planetary exploration.

  13. #NASA Set To Test #Space #Laser Comms At 240 Million Km With #Psyche #Asteroid
    Mission
    NASA will test a brand new #communications system with the Psyche mission, aiming to improve data transfer speeds significantly. This is part of NASA's #DeepSpace Optical Communications (#DSOC) test, which will place a transceiver equipped with a laser transmitter and a camera to send lasers to Earth and also receive laser communications from the home planet.

  14. #Psyche : The test periods for the #DeepSpace Optical Communications 📶 technology demonstration are indicated with dots jpl.nasa.gov/press-kits/psyche

    #DSOC operations are planned for about two years, beginning roughly 20 days after launch. The 5.1-meter Hale #Telescope 🔭 at Caltech’s Palomar Observatory* in San Diego County, #California, will receive the downlinked high-rate data from the DSOC flight laser jpl.nasa.gov/press-kits/psyche

    capabilities, which will be critical to communicate with #astronauts 👨‍🚀👩‍🚀 traveling to #Mars 🔴). NASA cannot use #RadioFrequency communications to carry higher data rates like those required for Mars without increasing
    the size of its antennas 📡 or power of its radio transmitters. Therefore, the Agency is developing #optical communications (use

  17. #DS9’s is not a theme song whose rhythm they should’ve gotten expressive with in the actual show opening. It relies so much on off-beat sequences that it’s hard to get where the beats are supposed to fall when they’re rubato-ing it up. #StarTrek #MusicGeek #StarTrekDS9 #DeepSpace9

  18. 📢 Scientists have found a mysterious source of oxygen at the bottom of the Pacific Ocean, far from any sunlight needed for photosynthesis. This phenomenon, discovered in a region rich with polymetallic nodules, suggests an unknown energy source might be splitting water molecules to produce oxygen. nature.com/articles/d41586-024
