SEATTLE, WA — Boeing hopes to restart 737 Max airline deliveries in December and resume commercial service in January, according to the Associated Press. The aircraft have been grounded since March 2018, when regulators in the U.S. and abroad found similarities between two deadly crashes in five months. In a progress report released Monday, the embattled aerospace company listed five "key milestones" that must be met before the FAA will greenlight a return to service.

The high-pressure turbine blades in a Trent 1000 passenger jet engine have to withstand temperatures far above the melting point of the nickel alloy from which they’re made. It’s a fiendish technical challenge for the engine’s British manufacturer, Rolls-Royce Holdings plc — comparable to trying to stop an ice cube melting inside a kitchen oven on full blast. The solution found by the company’s engineers: blow cool air through tiny holes in the blades. Unfortunately this clever approach has encountered some unexpected problems.Boeing 787 aircraft operated by British Airways, Norwegian Air Shuttle, Virgin Atlantic and others have been grounded in recent months for inspections and repairs because the Trent 1000 engine blades have been degrading faster than anticipated. It’s the type of problem that’s becoming common in the industry as the demands placed on engines become ever greater.The expense of dealing with these things is rising too.

Here are the stories you shouldn’t miss today: Newsletter Get our Essential California newsletter TOP STORIESWill These Hearings Be Unimpeachable? Advertisement Public hearings in the impeachment inquiry of President Trump are scheduled to begin this morning with testimony from State Department official George Kent and William B. Taylor Jr., the by-the-book senior U.S. diplomat in Ukraine. Both have already told lawmakers they were troubled by the president and his administration’s pressure on Ukraine to conduct investigations that would benefit Trump politically while holding up congressionally approved military aid to the U.S. ally. (Marie Yovanovitch, the former U.S. ambassador to Ukraine, will publicly testify Friday.)How it will play out on TV is anyone’s guess, but Democrats’ top challenge is to keep the proceedings serious and straightforward, but also engaging, while Republicans are looking to question the fairness and integrity of the … [Read more...] about Newsletter: Will these hearings be unimpeachable?
(CNN)For a little over a year, a tiny unmanned Japanese spacecraft has been sampling the surface of the near-Earth asteroid Ryugu, capturing images, blasting a little crater in it, and firing a "bullet" into its exterior to dislodge particles. Now, after traveling about 180 million miles, Hayabusa2 has begun its yearlong journey back to Earth with valuable data and soil samples in tow. The Japanese Aerospace Exploration Agency hopes to use the materials to explore the origins of the planets and the source of Earth's oceans. An image of Ryugu captured by Hayabusa2. The little spacecraft seems to already be experiencing twinges of nostalgia. As it slowly retreats from the asteroid it called home, Hayabusa2 has been snapping real-time photos of the asteroid as it departs and will continue this "Farewell Observation" until November 18. Ryugu is a diamond-shaped asteroid just under 3,000 ft wide that orbits tens of millions of miles away from Earth. Hayabusa2's venture, which … [Read more...] about A Japanese spacecraft is coming back to Earth with samples from a nearby asteroid
