Image: Space bauble produced by the Multiscale Boiling experiment
Tuesday, 22 December 2020 12:43
Deck the halls with space-based bubbles!
Here is a festive bauble you will not see on Earth: a bubble produced by the Multiscale Boiling experiment, known affectionately as Rubi.
In this image, electrostatic forces are pulling the bubble upwards and making it spherical, producing not only a cool image but also cool insights into the boiling process.
Understanding how boiling behaves in weightlessness is imperative because gravity plays an important role. Without gravity, boiling takes place in slow motion and produces larger bubbles. This has allowed scientists to observe and measure effects that are too fast and too small on Earth.
The experiment is also installed with an electrode to observe the effect of an electric field on the bubbles, enabling scientists to observe and quantify the effect of external forces.
"Boiling is an extremely efficient way of getting rid of excess heat. This research could therefore provide very valuable information for improving the thermal management systems in space as well as in terrestrial applications," says ESA project scientist Daniele Mangini.
With this insight and more accurate calculations of the boiling process, products such as laptops can be improved and made more compact.

FAA Begins Scoping Period for Environmental Review at SpaceX Launch Site
Tuesday, 22 December 2020 05:46
The Federal Aviation Administration (FAA) is holding a public scoping period for the draft Environmental Assessment (EA) related to plans by SpaceX to apply for licenses for suborbital and orbital launches of its Starship/Super Heavy project at its facility in Boca Chica, Texas.
The scoping period will help the FAA in determine the scope of issues for analysis in the draft EA. The FAA requ A Martian Roundtrip: NASA's Perseverance Rover Sample Tubes
Tuesday, 22 December 2020 05:46
Marvels of engineering, the rover's sample tubes must be tough enough to safely bring Red Planet samples on the long journey back to Earth in immaculate condition.
The tubes carried in the belly of NASA's Mars 2020 Perseverance rover are destined to carry the first samples in history from another planet back to Earth.

EMXYS and the Royal Observatory of Belgium have been selected by the European Space Agency to provide a gravimeter for the Juventas spacecraft that will land on asteroid Dimorphos as part of the European Space Agency's planetary defence programme.
EMXYS and the Royal Observatory of Belgium will provide the GRASS instrument that will make measurements on the gravity field of the asteroid Di The world's oldest story? Astronomers say global myths about 'seven sisters' stars may reach back 100,000 years
Tuesday, 22 December 2020 05:46
In the northern sky in December is a beautiful cluster of stars known as the Pleiades, or the "seven sisters". Look carefully and you will probably count six stars. So why do we say there are seven of them?
Many cultures around the world refer to the Pleiades as "seven sisters", and also tell quite similar stories about them. After studying the motion of the stars very closely, we believe Developing smarter, faster machine intelligence with light

An international research team involving Professor Federico Rosei of the Institut national de la recherche scientifique (INRS) has demonstrated a novel process to modify the structure and properties of graphene, a one atom thick carbon.
This chemical reaction, known as photocycloaddition, modifies the bonds between atoms using ultraviolet (UV) light. The results of the study were recently US Space Force enters 'Year 2' with momentum and soaring expectations

Tuesday, 22 December 2020 05:46
Vessels known to have crew that are subject to forced labor behave in systematically different ways to the rest of the global fishing fleet, reveals a new paper published in the scientific journal, Proceedings of the National Academy of Sciences. The discovery was used to build a first-of-its-kind model to identify and predict vessels at high risk of engaging in these abuses.

You have to look closely, but the hills are alive with the force of van der Walls.
Rice University scientists found that nature's ubiquitous "weak" force is sufficient to indent rigid nanosheets, extending their potential for use in nanoscale optics or catalytic systems.
Changing the shape of nanoscale particles changes their electromagnetic properties, said Matt Jones, the Norman an
