Our newest class of astronaut candidates graduated on March 5, 2024. This means they’re now eligible for spaceflight assignments to the International Space Station, the Moon, and beyond! In the next twelve posts, we’ll introduce these new astronauts.

Working on the front-end of the Spotify app. Flask API is done, just need to start the authentication part.
Still figuring out the design style I wanna go for (╥﹏╥)
Trust the process 🌿

Rockets, Racecars, and the Physics of Going Fast
When our Space Launch System (SLS) rocket launches the Artemis missions to the Moon, it can have a top speed of more than six miles per second. Rockets and racecars are designed with speed in mind to accomplish their missions—but there’s more to speed than just engines and fuel. Learn more about the physics of going fast:
Take a look under the hood, so to speak, of our SLS mega Moon rocket and you’ll find that each of its four RS-25 engines have high-pressure turbopumps that generate a combined 94,400 horsepower per engine. All that horsepower creates more than 2 million pounds of thrust to help launch our four Artemis astronauts inside the Orion spacecraft beyond Earth orbit and onward to the Moon. How does that horsepower compare to a racecar? World champion racecars can generate more than 1,000 horsepower as they speed around the track.
As these vehicles start their engines, a series of special machinery is moving and grooving inside those engines. Turbo engines in racecars work at up to 15,000 rotations per minute, aka rpm. The turbopumps on the RS-25 engines rotate at a staggering 37,000 rpm. SLS’s RS-25 engines will burn for approximately eight minutes, while racecar engines generally run for 1 ½-3 hours during a race.
To use that power effectively, both rockets and racecars are designed to slice through the air as efficiently as possible.
While rockets want to eliminate as much drag as possible, racecars carefully use the air they’re slicing through to keep them pinned to the track and speed around corners faster. This phenomenon is called downforce.
Steering these mighty machines is a delicate process that involves complex mechanics.
Most racecars use a rack-and-pinion system to convert the turn of a steering wheel to precisely point the front tires in the right direction. While SLS doesn’t have a steering wheel, its powerful engines and solid rocket boosters do have nozzles that gimbal, or move, to better direct the force of the thrust during launch and flight.
Racecar drivers and astronauts are laser focused, keeping their sights set on the destination. Pit crews and launch control teams both analyze data from numerous sensors and computers to guide them to the finish line. In the case of our mighty SLS rocket, its 212-foot-tall core stage has nearly 1,000 sensors to help fly, track, and guide the rocket on the right trajectory and at the right speed. That same data is relayed to launch teams on the ground in real time. Like SLS, world-champion racecars use hundreds of sensors to help drivers and teams manage the race and perform at peak levels.
Knowing how to best use, manage, and battle the physics of going fast, is critical in that final lap. You can learn more about rockets and racecars here.

ELM Evolv demonstrator, 2024. Prodrive Advanced Technology and Astheimer Design have revealed a ‘last mile’ L7e category electric quadricycle prototype with a cubic load capacity rivalling mid-size vans. At 3,240mm long, 1,450mm wide, 2,150mm high and weighing 850kg with batteries, the compact Evolv can accommodates a 1.6m tall Euro pallet with a 300kg payload in the main load area. The secondary load area, accessible through rear ‘barn doors’, provides additional space for a 1.2m tall Euro pallet and 200kg payload. Prodrive and Astheimer has established a new company, ELM Mobility, to take the project into the production readiness phase. The vehicle, which has a 20kWh battery, will offer a 100 mile range with sales starting in 2028 at a target price of around £25,000.

Summer days.
Volunteered at this uni thing, helping some high schoolers with python basics/exercises and it was pretty fun :)
I need to choose a minor for next year and I'm struggling guys
Biology, Multimedia Design or Geographic Information Systems? Bear in mind I don't have any biology bases 😭
