The sun spit out the huge flare along with a massive radio burst on Thursday, causing two hours of radio interference in parts of the U.S. and other sunlit parts of the world. Scientists at the National Oceanic and Atmospheric Administration said it was the biggest flare since 2017, and the radio burst was extensive, affecting even the higher frequencies.

Something has gone wrong with NASA's Ingenuity helicopter on the surface of Mars. Although the US space agency has not made any public announcements yet, a source told Ars that the plucky flying vehicle had an accident on its last flight and broke one of its blades. It will not fly anymore. (Shortly after this article was published, NASA confirmed the end of Ingenuity's mission).

When it launched to Mars more than three years ago, the small Ingenuity helicopter was an experimental mission, a challenge to NASA engineers to see if they could devise and build a vehicle that could make a powered flight on another world.

This was especially difficulty on Mars, which has a very thin atmosphere, with a pressure of less than 1 percent that of Earth's. The solution they landed on was a very light 4-lb helicopter with four blades. It was hoped that Ingenuity would make a handful of flights and provide NASA with some valuable testing data.

But it turns out that Ingenuity had other ideas. Since its deployment from the Perseverance rover in April 2021, the helicopter has flown a staggering 72 flights. It has spent more than two hours—128.3 minutes, to be precise—flying through the thin Martian air. Over that time, it flew 11 miles, or 17 km, performing invaluable scouting and scientific investigations. It has been a huge win for NASA and the Jet Propulsion Laboratory, one of the greatest spaceflight stories of this decade.

Plans for the coming move — setting into place the crown jewel of the new Samuel Oschin Air and Space Center — have been in the works for more than a decade. First, a pair of cranes will hoist the shuttle from a horizontal position to a vertical one; the spacecraft will be attached to a sling, a large metal frame that'll support it during the move. An 11-story crane will lift the tail of Endeavour, while a 40-story crawler crane — about the height of City Hall — will lift the nose.

Once the shuttle is pointed toward the stars, the shorter crane will be disconnected, leaving the taller crane to gently swing the orbiter to its final position and lowering it to be affixed with the giant orange external tank. The external tank is attached to twin solid rocket boosters, which are connected to the exhibit's foundation.

Once complete — and the rest of the museum is constructed in the coming years — L.A. will be home to the only retired space shuttle displayed in a full-stack arrangement as if ready for launch.
