Explanation and Demonstration of the Parker Solar Probe’s Heat Shield | #NASA @NASA
The Parker Solar Probe is scheduled to launch this month from Cape Canaveral to probe the outer corona of the Sun. (Trivia: the probe will ultimately become the fastest humanmade object in existence, achieving speeds of 120 miles per second while orbiting the sun due to gravitational assists.) The probe will get less than 4 million miles from the Sun where temperature is definitely a concern (for comparison Mercury is 9 times as far away at 36 million miles and it has surface temperatures exceeding 800F during the day!). The videos below both explain and demo how the relatively thin heat shield absorbs and essentially dissipates the incredible heat the probe will encounter. (Just don’t increase the brightness in the solar observation room…or sensor in this case.)
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
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.
