“The huge parachute used by NASA’s Perseverance rover to land on Mars contained a secret message,” reports the Associated Press — thanks to the rover’s puzzle-loving systems engineer Ian Clark.
“During a live stream discussing the landing, one Nasa commentator said: ‘Sometimes we leave messages in our work for others to find. So we invite you all to give it a shot and show your work,'” reports the Guardian.
One Reddit user actually deciphered the message using Python code.
Long-time Slashdot reader rufey writes that “Decoded the slogan is ‘Dare Mighty Things’ — a line from President Theodore Roosevelt — which is a mantra at JPL and adorns many of the center’s walls.” The orange sections of the 70-foot (21-meter) parachute represented ones in binary code, while the yellow sections represented zeroes. (So the letter “A” becomes yellow-yellow-yellow-yellow-yellow-yellow-orange…) The Associated Press reports:
Clark also included the GPS coordinates for the mission’s headquarters at the Jet Propulsion Laboratory in Pasadena, California. Clark, a crossword hobbyist, came up with the idea two years ago. Engineers wanted an unusual pattern in the nylon fabric to know how the parachute was oriented during descent. Turning it into a secret message was “super fun,” he said Tuesday. Only about six people knew about the encoded message before Thursday’s landing, according to Clark. They waited until the parachute images came back before putting out a teaser during a televised news conference Monday…
Another added touch not widely known until touchdown: Perseverance bears a plaque depicting all five of NASA’s Mars rovers in increasing size over the years — similar to the family car decals seen on Earth.
Deputy project manager Matt Wallace promises more so-called hidden Easter eggs…
The official Twitter feed for the rover has already revealed that it’s carrying another message hidden in a plaque with a logo of the sun — “Explore as One,” written in Morse code.
Some other interesting facts about the rover:
NASA points out that Perseverance carried a special placard with 10,932,295 names, “stenciled by electron beam onto three fingernail-sized silicon chips.”
Space.com notes that it also carried a small aluminum plate honoring the healthcare workers of the world.
NASA is encouraging children to code their own version of the helicopter using the visual programming language Scratch.
