How to plan the ultimate long-term project, from the team who got us to Pluto

NewImage

Fast Company has a fascinating post on long-term project planning from the New Horizons team.

One thing you don’t expect when planning a nine-year mission to the most distant planet in our solar system is the eventuality that Pluto might not be a planet once you got there.

Yet that’s exactly what went down in 2006. That January, NASA launched its unmanned New Horizons probe, a baby grand piano-sized, 1,054-pound spacecraft, on the first-ever route to Pluto. Then, in August 2006, the International Astronomical Union demoted Pluto to the diminutive status of “dwarf planet.”

The move “came out of left field” and shocked a lot of people, said Chris Hersman, the lead engineer on the New Horizons project. But as they say on Broadway, the show must go on. “I used to joke, ‘Well, we haven’t told the spacecraft.’”

Astronomers and planetary experts can debate Pluto’s status to the edge of the universe, but it doesn’t change the fact that nine years, five months, and 25 days after launching from Cape Canaveral Air Force Station in Florida, New Horizons made its much-heralded fly-by of Pluto today.

Planning a project whose culmination is nine years and more than 3 billion miles away requires rigorous risk assessment, strong leadership, and endless patience. Here’s how the team ultimately succeeded.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email circuitpython2022@adafruit.com to let us know about your post so we can blog it up here.

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.
