SIGN UP ⋅   WEBSITE   The Launchpad NASA's Mars plans need 'paradigm shifts' to succeed (NASA/JPL-Caltech/ASU/MSSS) NASA has released a new document that highlights planned programmatic paradigm shifts in Mars exploration over the next 20 years. This plan was prepared for the NASA Science Mission Directorate's Mars Exploration Program (MEP). The report is titled "Expanding the Horizons of Mars Science: A Plan for a Sustainable Science Program at Mars -- Mars Exploration Program 2024-2044."

But Earth isn't the only target; the moon is regularly bombarded with such meteors, and Daichi Fujii, the curator of the Hiratsuka City Museum in Japan, has captured some of the most recent collisions. Full Story: Space (12/12)  Skywatching Geminid meteor shower peaks tonight! (Li Xiang viaGetty Images)) The Geminid meteor shower, one of the most prolific meteor showers of the year peaks tonight, Dec. 13. Famed for its bright, vividly colored meteors, the Geminids promise a spectacle as Earth passes through the debris left behind by asteroid 3200 Phaethon. Under optimal conditions, the Geminids can produce up to 120 meteors per hour, but this year's near full-moon will likely wash out fainter meteors, reducing visibility. Still, if you have clear skies, it's worth braving the chill for a glimpse of this celestial treat. Full Story: Space (12/13)  Spaceflight We need to act now to prevent an orbital debris crisis (NASA) Earth orbit is getting more and more crowded, with both active satellites and pieces of debris. There's so much stuff up there that it's far from alarmist to start worrying about the Kessler syndrome, a nightmare scenario in which a collision or two leads to many more, vastly increasing the amount of junk circling our planet. "We have to get serious about this and recognize that, unless we do something, we are in imminent danger of making a whole part of our Earth environment unusable," Dan Baker, director of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder (UC-Boulder), said in a panel Wednesday (Dec. 11) at the 2024 meeting of the American Geophysical Union (AGU) in Washington, D.C.

But new measurements from Juno, coupled with archival data from the Galileo mission, have seemingly put to bed to the possibility of a magma ocean beneath the surface of Io. Full Story: Space (12/12)  Search for Life Extraterrestrial life may look nothing like life on Earth (kasezo via Getty Images) We have only one example of biology forming in the universe - life on Earth. But what if life can form in other ways? How do you look for alien life when you don't know what alien life might look like? These questions are preoccupying astrobiologists, who are scientists who look for life beyond Earth. Astrobiologists have attempted to come up with universal rules that govern the emergence of complex physical and biological systems both on Earth and beyond.

"SALLY," from National Geographic and director Cristina Costantini, reveals the legacy of NASA astronaut Sally Ride. Featuring archival footage filmed both on the ground and in space, along with new interviews with Ride's close friends and colleagues, the documentary allows access to the "real Ride," who struggled with the "limits and sacrifices true heroism demands."

Interconnection in magnonic networks: functional building blocks for an
alternative controllable way of spin-wave and quantum computation

The content of the talk is devoted to the possible integration of
magnonic devices and interconnection between them with the use of
magnonics, straintronics, spin-orbitronics. In recent years much
research has been directed towards the use of spin waves for signal
processing at microwave and subterahertz frequencies due to the
possibility to carry the information signal without the transmission of
a charge current. Recent theoretical and experimental studies suggest
that strain can be used to engineer energy-efficient complicated 2D and
3D material and heterostructures. The main topic of the talk will be
focused on the application of the magnonic unit for signal processing
and interconnection routes in the magnonic networks. The part of the
talk will be devoted to the the experimental observations of the
strain-mediated spin-wave coupling phenomena in different magnonic
structures based on the asymmetric adjacent magnonic crystals, adjacent
magnetic yttrium iron garnet stripes and array of magnetic stripes,
which demonstrates the collective spin-wave phenomena such as the
discrete soliton formation. The voltage-controlled spin-wave transport
along bilateral magnonic stripes was demonstrated. The model describing
the spin-wave transmission response and predicting its value is proposed
based on the self-consistent equations. It was shown that the
strain-mediated spin-wave channels can be used to route the magnonic
information signal and thus the composite magnon-straintronic structure
could be used to fabricate magnonic platforms for energy-efficient
signal processing. The obtained results open new perspectives for the
future-generation electronics using integrated magnonic networks.
