Twitter on Wednesday suspended an account that used publicly available flight data to track Elon Musk's private jet, despite a pledge by the social media platform's new owner to keep it up because of his free speech principles.

Then, hours later, Musk brought back the jet-tracking account after imposing new conditions on all of Twitter's users — no more sharing of anyone's current location.

A hacker who reportedly posed as the CEO of a financial institution claims to have obtained access to the more than 80,000-member database of InfraGard, an FBI-run outreach program that shares sensitive information on national security and cybersecurity threats with public officials and private sector actors who run U.S. critical infrastructure.

The hacker posted samples they said were from the database to an online forum popular with cybercriminals last weekend and said they were asking $50,000 for the entire database.

TikTok's algorithms are promoting videos about self-harm and eating disorders to vulnerable teens, according to a report published Wednesday that highlights concerns about social media and its impact on youth mental health.

What you're seeing in your feed on Twitter is changing. But how?

The social media platform's new owner, Elon Musk, has been trying to prove through giving selected journalists access to some of the company's internal communications dubbed "The Twitter Files" that officials from the previous leadership team allegedly suppressed right-wing voices.

NASA's Orion capsule made a blisteringly fast return from the moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.

The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants — three test dummies rigged with vibration sensors and radiation monitors.

Three Chinese astronauts docked early Wednesday with their country's space station, where they will overlap for several days with the three-member crew already onboard and expand the facility to its maximum size.

Docking with the Tiangong station came at 5:42 a.m. Wednesday, about 6 1/2 hours after the Shenzhou-15 spaceship blasted off atop a Long March-2F carrier rocket from the Jiuquan Satellite Launch Center.

A rocket carrying three astronauts to finish building China's space station will blast off Tuesday amid intensifying competition with the U.S., the government said Monday.

The crew includes a veteran of a 2005 space mission and two first-time astronauts, according to the China Manned Space Agency.

NASA's Orion capsule reached the moon Monday, whipping around the back side and passing within 80 miles (128 kilometers) on its way to a record-breaking lunar orbit.

The close approach occurred as the crew capsule and its three test dummies were on the far side of the moon. Because of the half-hour communication blackout, flight controllers in Houston did not know if the critical engine firing went well until the capsule emerged from behind the moon, more than 232,000 miles (375,000 kilometers) from Earth.

NASA's new moon rocket blasted off on its debut flight with three test dummies aboard early Wednesday, bringing the U.S. a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo program 50 years ago.

If all goes well during the three-week, make-or-break shakedown flight, the rocket will propel an empty crew capsule into a wide orbit around the moon, and then the capsule will return to Earth with a splashdown in the Pacific in December.

Facebook parent Meta is laying off 11,000 people, about 13% of its workforce, as it contends with faltering revenue and broader tech industry woes, CEO Mark Zuckerberg said in a letter to employees Wednesday.

The job cuts come just a week after widespread layoffs at Twitter under its new owner, billionaire Elon Musk. There have been numerous job cuts at other tech companies that hired rapidly during the pandemic.
