If you're as ancient as I am, you might remember that awesome line of Revell "Visible" model kits: The Visible Man, Visible Woman, Visible V-8, Visible Mustang, etc. These see-thru models were a fun way to teach kids what lies beneath the surfaces of biological and mechanical worlds. I loved these kits!
Now, thanks to the wonders of modern desktop animation, we have this video of four transparent rockets showing engine burn and staging, from launch to orbital insertion.

On at 8:55am local time on Saturday, November 23, 2019, the Chinese government "successfully" launched a Long March 3B carrier rocket into orbit. Leaving from the Xichang Satellite Launch Center, the Yuanzheng-1 upper was carrying two Beidou satellites—basically China's version of GPS.
I say "successfully" in quotes because, while the rocket and satellites reached their destination, they also happened to drop one of their lower rocket boosters on someone's house, along with some toxic propellant gas:
But worst of all? This isn't the first time in recent history that it's happened, either.
According to SpaceNews, residents within the calculated drop zones were given an evacuation notice, and advised against approaching the potential wreckage of their homes. Based on a quick perusal of comments on Twitter (and the ones I can parse from the Chinese social media service Sina Weibo), the Chinese government allegedly compensates people when something like this happens. I certainly hope that's true, though I wouldn't bet money on it. And even if it is, the fact that the government keeps launching rockets with the knowledge that the boosters may come down and destroy homes and lives is concerning enough.
Presumably, the Chinese government doesn't want to launch any rockets on the their coasts for fear of pissing off or threatening their neighbors—it's probably easier to handle your own citizens than deal with an accidental booster falling on someone in South Korea. Read the rest
Lockheed Martin just made the largest 3D printed part they've ever ever built for space. The titanium domes used to take a couple of years to make from scratch, but this was completed in about three months. Read the rest

Update: Apparently, Mitt was joking
At a $50,000/ticket fundraiser at the Beverly Hills Hilton (home to one of the great Trader Vic's of America, I might add), Mitt Romney expressed his controversial views on aerospace engineering, as recounted by the LA Times's Seema Mehta:
Romney’s wife, Ann, was in attendance, and the candidate spoke of the concern he had for her when her plane had to make an emergency landing Friday en route to Santa Monica because of an electrical malfunction.
“I appreciate the fact that she is on the ground, safe and sound. And I don’t think she knows just how worried some of us were,” Romney said. “When you have a fire in an aircraft, there’s no place to go, exactly, there’s no — and you can’t find any oxygen from outside the aircraft to get in the aircraft, because the windows don’t open. I don’t know why they don’t do that. It’s a real problem. So it’s very dangerous. And she was choking and rubbing her eyes. Fortunately, there was enough oxygen for the pilot and copilot to make a safe landing in Denver. But she’s safe and sound.”
I expect that's the sort of insight into technology that Romney acquired while creating jobs by remaking American industry to be more efficient.
