One of the biggest computational fluid dynamics simulation made on a super computer This is one of the largest CFD simulations ever, on the world's largest GPU server, the GigaIO SuperNODE, equipped with 32x AMD Instinct MI210 64GB GPUs, for a total of 2TB of VRAM. The simulation shows the Concorde (62m long) before landing at a speed of 300km/h and an angle of attack of 10°, for 1 second in flight. The span-based Reynolds number is 146 million.

Jeff Bezos in space with a Blue Origin rocket Tuesday, July 20, 2021, nine days after billionaire Richard Branson's space trip aboard Virgin Galactic's VSS Unity spacecraft, Jeff Bezos, founder of Amazon and the richest man in the world, also surrendered, accompanied 3 other passengers, in space aboard a capsule powered by the reusable New Shepard rocket from his company Blue Origin. Take-off took place from Launch Site One, the company's launch base located in West Texas, then the capsule was dropped at an altitude of 75 km to then slightly exceed 100 km in altitude, space border according to the International Aeronautical Federation. After 3 minutes of orbital flight, for a total flight of 11 minutes, the capsule made its return to Earth, braked by three parachutes and retro rockets. The New Shepard launcher also returned to a landing pad near the launch site.
Τα συντρίμμια από έναν πύραυλο SpaceX φωτίζουν τον ουρανό Το απόγευμα της Πέμπτης 25 Μαρτίου του 2021, ένας κάτοικος του Newberg του Όρεγκον κατέγραψε μια εκπομπή φωτός που προκλήθηκε από συντρίμμια ενός πυραύλου της SpaceX καθώς επέστρεφε στην ατμόσφαιρα. Ήταν συντρίμμια από το δεύτερο στάδιο ενός πυραύλου Falcon 9. "Αυτό που φαίνεται στον ουρανό είναι ένας πύραυλος που πέφτει στην ατμόσφαιρα με ταχύτητα πάνω από 27.000 χλμ/ώρα και θρυμματίζεται από τη θερμότητα" δήλωσε ο Jonathan McDowell, από το Κέντρο Αστροφυσικής του Χάρβαρντ. Δεν έχει αναφερθεί καμία ζημιά.
Starship SN9 flight and crash SpaceX has tested the ninth Starship prototype in a row.
It is not yet known whether the landing accident was caused by low tank pressures than with the SN8, or something else.
Led by the standing ship SN10, which in turn, did not suffer any serious damage in the explosion.
