SIGN UP ⋅   WEBSITE   The Launchpad Dana Weigel will be the 1st female ISS program manager (NASA) NASA's Dana Weigel was named incoming permanent program manager for the International Space Station (ISS) on Monday (Feb. 26), succeeding Joel Montalbano. As Weigel takes office on April 7, she will become the first woman to serve in the role. Full Story: Space (2/27)  Odysseus sends back more photos from moon landing (Intuitive Machines) Odysseus touched down about 190 miles (300 kilometers) from the moon's south pole on Thursday (Feb. 22), becoming the first private spacecraft ever to land softly on Earth's nearest neighbor - and the first American vehicle to do since since the final Apollo mission in 1972. We just got a fresh look at Odysseus' epic descent, thanks to three new photos from Intuitive Machines. Full Story: Space (2/27)  Total Solar Eclipse 2024 Free solar filter with purchase of Unistellar telescope (Unistellar) The free smart solar filter that comes with a telescope of your choice from Unistellar's website allows you to view the solar eclipse on April 8 safely. We strongly recommend using safe solar equipment to view the eclipse and of course, once the eclipse is over, you will still have a top piece of kit so you can have great views of the stars and beyond. Plus, you can safely observe the sun during the day without running the risk of damaging the telescope or its sensitive image sensor.

The company announced Tuesday (Feb. 27) that it had conducted a static fire test with the Falcon 9 rocket that will launch the Crew-8 mission to the International Space Station (ISS) for NASA. Static fires are common prelaunch trials in which a rocket's engines are ignited briefly while the vehicle is anchored to the pad.

The stripping appears to be caused by electric currents created as the planet races around its red dwarf host star.

Уважаемые коллеги!

 В пятницу 1 марта в 11:30 состоится коллоквиум, на котором будет
заслушан доклад:

Владимир Енальдиев (Абрикосовский центр теоретической физики, МФТИ)
*Impact of lattice reconstruction on electronic properties of twistronic
heterostructures hosting long-period moiré superlattice*

In the talk I describe a multiscale approach to lattice relaxation of
long-period moiré superlattice in marginally twisted bilayers [1,2].
Based on that I introduce a concept of interface ferroelectricity
emerging as an array of polar domains with alternating out-of-plane
polarization in twistronic heterostructures consisting of 2D material's
layers lacking of inversion symmetry [3]. For the structures based on
twisted transition metal dichaIcogenides bilayers I present a domain
wall network model which predicts a universal scaling of polar domain
structure in external out-of-plane electric field [4]. Second part of my
talk will be devoted to modelling of graphene-based twistronic
heterostructures using hybrid kp-tight-binding Hamiltonians [5]. In
particular, I will describe electronic properties of AB/BA domain wall
in bilayer graphene [6] and show that single-element structures such as
few-layer rhombohedral graphite stacks with twin boundary plane can host
weak ferroelectricity [7].
