Simulating entry… Using our LAVA software, Ames engineers performed simulations of a conceptual Mars spacecraft during entry. Here, the vehicle travels at supersonic speed (Mach 2.4) and uses retro-propulsion to decelerate further.

The animation depicts temperature, with purple representing lower and yellow higher temperatures. Simulations like this help researchers develop best practices to yield reliable, accurate predictions for aerodynamic drag throughout the spacecraft's possible entry, descent, and landing trajectories.

Firing rockets forward at Mach 2.4 is a wild engineering challenge. 🚀 The physics inside that LAVA simulation are incredible!

There are pockets where the yellowish part curls towards the vehicle centre of symmetry axle (parallel with the direction) and they are rotating as if there wouldn't be any external forcing, the pressure created by the 2.4 Mach velocity, on the system.

Oh please, you are 5% ready for deep space travel, here is the other 95%. all NASA bottlenecks of 30 years beaten, "all" there is even a separate journal with NASA Scalps you can download. All double AI vetted for physics as build now

Why not use this on every entry? First thing I noticed was the gas shield it creates out front. Seems like a cheap extra insurance layer that's simple to add?

A startup called Inversion has introduced Arc, a space-based vehicle designed to deliver cargo anywhere on Earth in under an hour. It can travel at Mach 25 during re-entry, store cargo in orbit for up to 5 years, and land autonomously using an AI-guided system. Built with support from NASA Ames Research Centre, it will first serve defence missions, with full global delivery operations planned by 2028.

Dana for software-defined vehicles brings the speed of AI to development workflows. We built Dana to reimagine how physical AI applications get developed, including the vehicle software development lifecycle—adding an agentic layer so engineers can build, code, and ship intelligent vehicle features faster and at scale.

🚀 Breaking New Ground in Supersonic Flight! Carried by a Starfighters F-104 aircraft, last week GE Aerospace announced it has successfully completed supersonic captive carry flight tests of its ATLAS Flight Test Vehicle, marking a major milestone in advancing solid fuel ramjet (SFRJ) propulsion technology. 🌍✈️ The system reached supersonic speeds during three successful flights at Kennedy Space Center. This achievement showcases the potential of air-breathing propulsion to extend the range of munitions and paves the way for future high-speed systems. See more on how the team is continuing to evolve and grow the technology.

Good Morning from El Paso, Texas! I'm here with a group of NACo Digital Team & NYSAC colleagues touring entry points into the US and how migrants and asylum seekers are processed upon entry. Currently I'm at Paso del Notre entry point, one of the busiest entry points to the US.

Meet Blue Origin's Mars Telecommunications Orbiter (MTO), a high-performance spacecraft built upon our existing and affordable Blue Ring platform that is ready to support NASA’s Mars mission in 2028. The orbiter builds upon Blue Origin’s Mars Next-Generation Relay and Mars Sample Return architecture commercial proposals and creates a high-speed telecommunications relay network for coverage between Earth and Mars. Our orbiter's hybrid propulsion, maneuvering capability, and capacity greatly expand the windows to get to the Red Planet. MTO also provides powerful edge and AI computing benefits to help with Mars science and exploration missions. Learn more:

Mission Gaganyaan: 🔸VSSC/ISRO, in collaboration with ADRDE/ DRDO , successfully conducted Drogue Parachute Deployment Tests at the RTRS facility in Chandigarh. 🔸Drogue parachutes, armed with pyro-based mortars, stabilize and decelerate the crew module during re-entry to ensure a smooth descent. 🔸The tests instil assurance for integrating drogue parachutes into the Test Vehicle-D1 mission.

The Boeing 2707 is probably the supersonic airliner that most of you have never heard of before? It was Boeing’s entry into the late 1960’s race to build a supersonic airliner. In the end… they came 3rd in a three horse race. The Soviets flew first, went supersonic first, and went beyond Mach 2 first. Despite not being a commercial success, the Tu-144 will always be the first SST. Did you ever know about this?

Mars in motion! ⏩ While on its way to explore a mysterious, metal-rich asteroid, our Psyche spacecraft sped by Mars for a gravity assist to pick up speed and adjust its trajectory. As it approached the planet, it captured this series of high-res snaps.

With no Smart, JJ deployed Thiero on Jenkins for a brief stint. Thiero uses his speed/strength to chase Jenkins + fight thru Harris' offball screen. Then switches to Harris and fronts to prevent entry pass. Runs hard in transition, but was a bit out of control at the rim lol.

New interview of Anthropic's CEO Dario Amodei on AI's job impact: Entry-level office work gets hit first. "Tthe first thing to be disrupted is these kind of entry-level white-collar jobs: data entry, document review for law, or the stuff you’d give a first-year in finance where you’re analyzing documents. I still think those are going pretty fast. But I actually think software might go even faster because of the reasons I gave. I don’t think we’re that far from models being able to do a lot of it end-to-end. What we’re going to see first is the model only does a piece of what the human software engineer does, and that increases their productivity. Then, even when the models do everything that human software engineers used to do, the human software engineers take a step up. They act as managers and supervise the systems." --- Video from "Interesting Times with Ross Douthat + New York Times Opinion + New York Times Podcasts" YT channel (link in comment)

ICE agents in Portland, Oregon conduct a forcible entry into an apartment to arrest to illegal invaders. Reportedly they had attempted to arrest one of them during a traffic stop earlier but he fled and evaded pursuit; eventually crashing into a USPS vehicle. ICE agents attempted a "call out" but the illegal refused to come out resulting in the forcible entry seen here.... #CityLife #portland #ICE #BorderPatrol #crime #illegals #invader #invasion #CQB #FAFO #urban #democrats

Stoke Space is developing a fully reusable rocket designed to reuse both its first and second stages. The first stage lands like Falcon 9, while the second stage returns to Earth after delivering its payload using a unique engine with 30 thrust chambers. Its actively cooled heat shield uses cryogenic fuel to protect the rocket during the intense heat of re-entry.
