European Space Agency’s Reusable Prometheus Rocket Engine Will be Ground Tested in 2021
The future of space travel is with reusable rockets. They will reduce budgets and make it possible to launch missions at a faster pace. SpaceX has pioneered the reusable rocket, and now the European Space Agency is taking the ball with the Prometheus rocket engine. From SlashGear:
The agency anticipates this rocket engine costing only 1/10th that of the Ariane 5 Vulcain 2 main stage engine. Prometheus will be suitable for both the upper stage and main stage usage, according to the ESA, joining other features to be ‘highly flexible.’
At this time, the engine’s main subsystems are being manufactured, a process that includes additive layer manufacturing (ALM) that constructs the components one layer at a time. This process is faster than traditional methods, which are also unable to produce some of the complex parts required for the design.

Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
