Working on the SUBSA experiment. It stands for "Solidification Using a Baffle in Sealed Ampoules" which doesn't help much to understand what is going on admittedly. We were processing samples of metal alloys for researchers to observe how they are cast. Metallurgy is a hot subject for space research (not only because of the casting temperatures #dadjoke) because how metals form is complicated, very precise, and as metals are used everywhere on Earth improving them could have enormous benefits. As metals form, they grow crystals that resemble Christmas trees, and these crystals influence the strength of the metal. On Earth gravity influences how these crystals grow, so observing the process in space helps to understand the process, making it easier for researchers to create mathematical models. ESA has a facility called the Electromagnetic levitator in the Materials Science Laboratory to conduct research in this same domain. After the bronze age and iron age this type of research could lead to another metal age... 😎 An observant viewer will notice that I am wearing different t-shirts – no I didn't spill any (they are in sealed ampoules remember!) but the experiment runs over many days, actually the Materials Science Laboratory was running similar metal batches in Columbus too!
L’expérience SUBSA sur laquelle j’ai déjà travaillé plusieurs fois (les plus observateurs auront remarqué les t-shirts différents 😉) : en gros, c’est de la métallurgie spatiale. Les alliages sont un sujet assez chaud pour la recherche spatiale, et pas seulement à cause de leur température de fusion (je ne résiste pas à la blague de papa 😄). L’amélioration des alliages, omniprésents dans notre vie moderne, a évidemment un potentiel d’applications immense sur terre. Les métaux se forment en poussant comme des cristaux (avec une forme un peu sapin de noël si on a de l’imagination), et ces processus sont fortement influencés par la pesanteur, d’où l’idée d’enlever ce facteur pour mieux les appréhender. Après le bronze et le fer, ces recherches pourraient donner naissance à un nouvel âge du métal 👍

Everywhere I go in this house, I find your little science experiments; sitting on countertops, growing in cupboards, and taped to windows.

"Science without religion is lame, religion without science is blind"

Built for DA4: Hammer to Fall, the Military Science R&D Lab requirements were that it had at least three levels with a means to transport between them, built in the lego set "dollhouse" style, five minifigs, a support vehicle, and weapon being tested on a firing range, with bonus points for making lego box art.
The Institute accomplishes those tasks:
Build style, check.
Five Minifigs- Ted, the accountant on the top floor. Lisa and Frank, the weapons testers near the cannon. RDJ23, the science bot on the far side. And (unnamed) the test subject in field.
To simulate a weapons range I created a small set of targets for the main gun.
To transport through the building the figs use a series of bi-color portals. Each color corresponding to the same color on another floor.
Finally, they have a catapult ramp for a little scoot.
Hope you enjoyed it! Look for more DA4 stuff in that group over there!

It's a bit of an odd angle, I know, but it kept catching my eye as I flicked through my archives...

Rocket science in progress. I found this fence/gate in Disney California Adventure Park at Disneyland. This was behind the washrooms near 'Soaring over California' ride in a flight themed area of the park. I took this picture thinking to put a print on my son's door when he is older.
Karen St. Germain, director of the Earth Science Division of NASA’s Science Mission Directorate, answers a question during a briefing on NASA’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument, Tuesday, March 14, 2023 at the Smithsonian’s National Air and Space Museum in Washington. NASA’s TEMPO instrument, the first Earth Venture Instrument mission, will measure air pollution across North America from Mexico City to the Canadian oil sands and from the Atlantic to the Pacific hourly and at a high spatial resolution. A partnership between NASA and the Center for Astrophysics | Harvard & Smithsonian, TEMPO will launch on a commercial satellite to geostationary orbit as early as April.

My Daughter's school had their science fair this evening.
This was not her project, but I loved this one. It just cracked me up.
Science Festival, University of Cambridge. Dr Chris Smith and an official of the Science Festival outside the New Museums Site in Pembroke Street yesterday. Chris is one of the famous Naked Scientists: www.thenakedscientists.com/ . That's details of the Corpus Clock / Chronophage on the banner.
More on the festival here: www.admin.cam.ac.uk/sciencefestival/ .
Look carefully...a tree growing shoes...? only in London.

Profession gardien de Zoo à mi-temps, il faut assurer le repas bi-hebdomadaire des tardigrades de l’expérience Cell Science 4 🔬. Les chercheurs étudient les effets de l’impesanteur et de l’environnement spatial sur ces créatures microscopiques qu’on surnomme parfois oursons d'eau. L’espèce la plus grande peut mesurer jusqu’à 1 mm de long, mais en général ils sont microscopiques… Ces créatures sont incroyablement résistantes, capables de survivre à des environnements extrêmes sur Terre comme dans l’espace : certains sont revenus de plusieurs jours à l’extérieur, dans le vide, avec des températures de +100 à -100 degrés, sans un dommage... Dans le cas de Cell Science 4, les scientifiques essayent d’identifier les gènes qui leur permettent de survivre durant des séjours plus ou moins longs dans l’espace, et d’évaluer comment l’utilisation de ces gènes change au cours des générations dans le but d’exploiter pour les humains les secrets de leur incroyable résilience !
Feeding the tardigrades! 🌱 Researchers are investigating the effects of microgravity on these microscopic creatures, also known as water bears, through an experiment called Cell Science 4🔬 #DYK the largest tardigrade species is just over 1mm in length and they're incredibly hardy – surviving extreme environments in space and on Earth. In this case, researchers want to characterise the genes that allow tardigrades to survive during short and long periods in space, then assess how the use of these genes changes across generations Maybe we can harness their secrets!
