CAPE CANAVERAL, Fla. (AP) — The huge parachute used by NASA’s Perseverance rover to land on Mars contained a secret message, thanks to a puzzle lover on the spacecraft team.
Systems engineer Ian Clark used a binary code to spell out “Dare Mighty Things” in the orange and white strips of the 70-foot (21-meter) parachute.He 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.
It took just a few hours for space fans to figure it out, Clark said. Next time, he noted, “I’ll have to be a little bit more creative.”
“Dare Mighty Things” — a line from President Theodore Roosevelt — is a mantra at JPL and adorns many of the center’s walls. The trick was “trying to come up with a way of encoding it but not making it too obvious,” Clark said.
As for the GPS coordinates, the spot is 10 feet (3 meters) from the entrance to JPL’s visitor center.
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.
Clark suspects there are even more so-called hidden Easter eggs, but adds: “I’m not even privy to them.”

Mars helicopter reaches "big milestone" on flight to planet
So far, so good for the small helicopter that is poised to become the first to fly in outer space. NASA announced that the Mars Ingenuity helicopter is alive and well and was successfully recharged while in mid-spaceflight.
Ingenuity is currently positioned in the belly of the Perseverance rover, which launched last month on a historic mission to the red planet. NASA announced that the rover's power supply successfully brought the rotorcraft's six lithium-ion batteries to a charge of 35% -- the optimal level to keep the batteries healthy during the cruise to Mars.
"This was a big milestone, as it was our first opportunity to turn on Ingenuity and give its electronics a 'test drive' since we launched on July 30," said Tim Canham, the operations lead for Mars Helicopter. "Since everything went by the book, we'll perform the same activity about every two weeks to maintain an acceptable state of charge."
Once Perseverance touches down on Mars, the batteries will be charged by the helicopter's solar panel, NASA said. If Ingenuity can withstand the cold Martian nights, the team will go forward with test flights.The Mars Ingenuity helicopter in a NASA video demonstration. NASA
"This charge activity shows we have survived launch and that so far we can handle the harsh environment of interplanetary space," said project manager MiMi Aung. "We have a lot more firsts to go before we can attempt the first experimental flight test on another planet, but right now we are all feeling very good about the future."
The 4-pound helicopter will attempt to fly solo a few months after the rover touches down on Mars. It will first try to rise 10 feet into the planet's extremely thin atmosphere and fly forward up to 6 feet. With each attempt, it will try to go a little higher and farther.Perseverance Mars Rover Perseverance Mars Rover More
