Elon Musk’s companies enjoy paying each other lots of money.

Tesla paid X $280,000 for advertising and other services, according to the company’s proxy statement. X paid Tesla $1.02 million for unspecified work. SpaceX paid Tesla $2.9 million for “certain commercial, licensing and support agreements.” Tesla paid SpaceX $800,000 for use of its corporate jet. And Tesla paid the Boring Company $1.2 million.

No one paid Neuralink anything.

This Earth Day, help Apple make money off your old phone.

That’s what the company’s Earth Day recycling ads are really about, at least according to this scathing blog from iFixit. It’s a fun, informative read — and good reminder to keep an eye out for greenwashing this time of year.

Apple says it’s making progress on cleaning up its supply chain.

It’s using three times as much “clean electricity” now as it did in 2020, Apple said today. It’s part of the company’s commitment to become carbon neutral across its operations and supply chain by 2030. By the same date, Apple also plans to replenish fresh water it uses in drought-stressed areas — spending $8 million on that task since 2023.

First crewed Boeing Starliner mission will launch on May 6th.

The spacecraft is being readied to carry astronauts Barry Wilmore and Suni Williams to the International Space Station, with liftoff from Cape Canaveral scheduled for no earlier than 10:34PM ET.

The crew is expected to spend about a week at the orbiting laboratory before their capsule makes an airbag and parachute-assisted landing in the southwestern United States.

Until we meet again, Ingenuity.

After making its final flight in January, NASA’s Mars helicopter has transmitted its last message to Earth and will now serve as a stationary testbed for collecting up to 20 years’ worth of data. Teddy Tzanetos, Ingenuity’s project manager, gave it this moving farewell:

“Whenever humanity revisits Valinor Hills — either with a rover, a new aircraft, or future astronauts — Ingenuity will be waiting with her last gift of data, a final testament to the reason we dare mighty things. Thank you, Ingenuity, for inspiring a small group of people to overcome seemingly insurmountable odds at the frontiers of space.”

Can mirrors in space bounce solar energy down to Earth?

The European Space Agency plans to find out with a project called Solaris. Scientists and engineers have been trying to figure out how to make space-based solar power work since the 1960s. And the rise of the commercial space industry is finally bringing launch costs down enough to really put the technology to the test.

Anker’s latest Soundcore Sleep earbuds actually improve slumber

Verge Score

The Soundcore Sleep A20 are decent passive earbuds that are great for side sleepers, even if Anker overpromises.

Woohoo!

Newsweek notes that renewable energy hit a milestone in California, meeting 100 percent of the state’s electricity demand for up to 6 hours nearly every day of the past month.

There’s obviously still a lot of progress needed to hit the state’s goal of running entirely on carbon-free electricity by 2045, but Stanford engineering professor Mark Jacobson says this is a sign that California is well on its way there.

Mark Jacobson: “Once again, California exceeds 100% of demand on its main grid with #WindWaterSolar. This is the 30TH OF THE PAST 38 DAYS that #WWS supply has exceeded demand for 0.25-6 h per day.”
