Apple reportedly hired a longtime Ford executive for its car project

Apple has hired a longtime Ford engineer and executive to work on its long-gestating car project, according to Bloomberg. Desi Ujkashevic had been with the automaker since 1991. Before leaving the company in March, Ujkashevic was Ford’s global director of automotive safety engineering.

She previously oversaw the global body engineering team, safety engineering for Ford of Europe and the global design technical operations division. In her early years at Ford, according to her LinkedIn profile, Ujkashevic held roles in vehicle engineering, testing and durability. She has also worked on Ford’s electric vehicle efforts and regulatory issues. In other words, she seems like exactly the kind of person you’d want to hire for an EV project.

Apple is said to have started work on an autonomous vehicle in 2015. However, those efforts have suffered several setbacks over the years, partly as a result of strategy and staffing changes. Doug Field, who was said to have led Project Titan, left Apple to rejoin Ford last September. However, the reported hire of Ujkashevic is another indication that Apple is still trying to build its own EV.

For what it’s worth, in a recent LinkedIn post, Ujkashevic said she was “excited to start my next adventure and I hope to continue to contribute to society and advancing technology with a purpose […] ultimately making a better world!”

Listen to the sound of a black hole feeding on stellar material

A team of MIT scientists is looking for black hole echoes in an effort to shed some light on the regions of spacetime that largely remain a mystery to us. See, black holes only show any semblance of activity when they feed on gas and dust from one of their orbiting stars. When they do, they give off bursts of X-ray light that echo off the gas being consumed and which illuminate their surroundings. That’s what a black hole echo is. While it’s technically an X-ray echo, the team worked with MIT education and music scholars to turn the emission into audible sound waves you can listen to below.

For their new study, the astronomers developed an automated search tool called “Reverberation Machine” to comb through data gathered by NASA’s Neutron star Interior Composition Explorer, the X-ray telescope aboard the ISS. Their algorithm identified 26 black hole X-ray binary systems, which are systems with a star that’s being consumed by a black hole at times. Ten of them are close enough for the echoes to be observable, and eight were previously not known to emit echoes. 

So what did the team find out by analyzing the echoes? They found that the black holes initially go through a “hard” state upon feeding, wherein it forms a corona of high-energy photons and launches a jet of high-energy particles close to the speed of light. This state lasts for several weeks. After one last high-energy flash when the corona and jet die out, the black hole enters a “soft,” low-energy state. 

The scientists believe that these findings can help explain how supermassive black holes at the center of galaxies can help shape their formation. As Erin Kara, assistant professor of physics at MIT, said:

“The role of black holes in galaxy evolution is an outstanding question in modern astrophysics. Interestingly, these black hole binaries appear to be ‘mini’ supermassive black holes, and so by understanding the outbursts in these small, nearby systems, we can understand how similar outbursts in supermassive black holes affect the galaxies in which they reside.”

Rocket Lab captures booster in mid-air with a helicopter for the first time

Rocket Lab has taken a huge step towards making its Electron orbital launch vehicle a reusable rocket. The company has successfully captured Electron’s first stage mid-air with a helicopter for the first time upon its return to Earth after deploying 34 satellites to orbit. To ensure that the first stage will survive its re-entry into the atmosphere, Rocket Lab re-oriented it into the ideal angle that would give it the best chances to withstand tremendous heat and pressure. A drogue parachute then deployed to increase drag before the main parachute opened up in the final part of its descent.

The company sent a Sikorsky S-92 helicopter to rendezvous with the returning stage at 6,500 feet in the air, using a hook on a cable to capture the booster’s parachute line. While the catch was a success, Rocket Lab CEO Peter Beck said on Twitter that the pilots weren’t happy with the way the booster was hanging below the helicopter and opted to drop it into the ocean. It was eventually retrieved and loaded onto a vessel for transport back to Rocket Lab’s HQ for re-flight assessment. 

Rocket Lab says the test gave its helicopter pilot “different load characteristics than previously experienced in testing” and will provide important information for future helicopter captures. The goal is to be able to grab the booster mid-air and bring it straight back to land instead of having to drop it into the sea, since salt water could damage the booster. If the company successfully proves that it can reuse its boosters similar to what SpaceX can do, it can ramp up launch frequency and reduce mission costs for small satellites.

Rocket Lab CEO Peter Beck said:

“Bringing a rocket back from space and catching it with a helicopter is something of a supersonic ballet. A tremendous number of factors have to align and many systems have to work together flawlessly, so I am incredibly proud of the stellar efforts of our Recovery Team and all of our engineers who made this mission and our first catch a success. From here we’ll assess the stage and determine what changes we might want to make to the system and procedures for the next helicopter catch and eventual re-flight.”

The company has another launch scheduled for May, but it’s unclear if it will attempt another helicopter recovery.

Watch Rocket Lab try to capture a booster in mid-air with a helicopter

Rocket Lab is trying something different during today’s launch of Electron, its reusable rocket. The space company will attempt a mid-air capture of Electron’s first stage as it plummets back to Earth. In order to do this, Rocket Lab is deploying a Sikorsky S-92 helicopter, a twin-engine helicopter that can seat 19 people and is often used for military or presidential purposes. While recovery missions for rocket stages are uncommon — most end up on the ocean floor — the company’s goal is to create a truly reusable rocket that will allow for more frequent launches.

Rocket Lab has recovered boosters three times in the past, first in November 2020 with a parachute, followed by two sea recoveries in May and November 2021. But this will be the first mid-air retrieval of a booster with a helicopter. Space X — the only other space company that has successfully recovered its boosters— usually relies on drone ships.

Electron is scheduled for lift-off on May 2nd at 6:35PM ET from New Zealand’s Mahia Peninsula, Roughly two and a half minutes after launch, the first and second rocket stages will separate. The first stage, outfitted with a parachute and a heat shield to protect it from the harsh forces of the atmosphere, will then descend back to Earth. The helicopter at this point will then hook on to the parachute and recover the booster.

You can watch a live webcast of the launch (and hopefully, the subsequent recovery) below on Rocket Lab’s YouTube channel.
