After travelling all night to return from the International Space Station, two NASA astronauts will splashdown in the Gulf of Mexico at 11:48 PT, reports CNET. "There will be about an hour of excitement prior to that moment as Crew Dragon deorbits and re-enters Earth's atmosphere..."

That 11-minute deorbiting burn should begin in five minutes (at 10:56 PT), and you can watch it live on SpaceX's YouTube channel before the splashdown 52 minutes later. CNET notes that "This will be the first crew recovery at sea of NASA astronauts since 1975 at the end of the Apollo moon exploration era, the space agency tweeted on Sunday." The reentry process is dramatic. "Crew Dragon will be traveling at orbital velocity prior to reentry, moving at approximately 17,500 miles per hour. The maximum temperature it will experience on reentry is approximately 3,500 degrees Fahrenheit," said NASA in a statement on July 24...

If Crew Dragon passes these final tests, then SpaceX will be able to provide regular, operational flights to the ISS starting later this year. And it would end NASA's reliance on Russian spacecraft for the first time since the shuttle era.
After splashdown the crew "will spend up to an hour floating inside the capsule before joint recovery teams from SpaceX and NASA retrieve them for a helicopter trip ashore," reports Reuters.

A post-splashdown news conference is then scheduled about 30 minutes later at 1:30 p.m. PT.

McGruber writes: The Wall Street Journal is reporting that the Boeing Corporation fired its Chief Executive Officer Dennis Muilenburg (Warning: source paywalled; alternative source) as the company struggles to contain the fallout of its biggest crisis in decades, caused by two fatal crashes and the subsequent grounding of its 737 MAX jetliner. Boeing said David Calhoun, a longtime Boeing director with deep ties to the aviation and private-equity industries, will become CEO on January 13.

"Regulators had criticized Mr. Muilenburg's efforts to reassure customers and the financial community that government approval of a fix for the MAX was coming soon -- optimism that repeatedly proved misplaced," reports The Wall Street Journal. "The new leadership team made it clear in public statements Monday that they won't get ahead of regulators in predicting the return to service of the 737 MAX after its grounding in March following twin crashes that claimed 346 lives."

"An engineer by training, Mr. Muilenburg appeared to often rely heavily on data and legal advice rather than diplomacy in formulating his response to the escalating crisis, and his approach sometimes exacerbated friction with customers and regulators. His relationship with FAA leaders deteriorated to the point that about two weeks ago agency chief Steve Dickson publicly called out the company's failures to provide complete and timely data supporting proposed MAX software fixes."

And if you work in an environment where there are multiple Unix machines, they probably have funny names that are variations on a theme. No, you're not the only one! This article explores the phenomenon, showing that even the CIA uses a whimsical server naming scheme." What are some of your best (worst?) naming schemes?

holy_calamity writes "A US government program is in the works to design small nuclear reactors for use by developing countries. The work continues despite fears about security and nuclear proliferation. Plans include having reactors supplied with fuel by the US and other trusted nations, or to build reactors with their whole lifetime of fuel packaged securely inside — like a giant non-user replaceable radioactive battery.'

garlicnation writes "Gizmodo reports that robots that have the ability to learn and can communicate information to their peers have learned to lie. 'Three colonies of bots in the 50th generation learned to signal to other robots in the group when then found food or poison. But the fourth colony included lying cheats that signaled food when they found poison and then calmly rolled over to the real food while other robots went to their battery-death.'"

mlauzon writes with the news that YouTube's co-founder Steve Chen has announced high-quality video streams are in the works for the popular site. He spoke today at the NewTeeVee Live event, discussing the challenges facing the project and when we can expect to see less grainy social videos. "The need to buffer the video before it starts playing will change the experience. Hence the experiment, rather than just a rapid rollout of this technology. On stage, he said the current resolution of YouTube videos has been "good enough" for the site until now. Chen told me he expects that high-quality YouTube videos will be available to everyone within three months. Chen also confirmed that in YouTube's internal archive, all video is stored at the native resolution in which it was sent. However, he said, a large portion of YouTube videos are pretty poor quality to begin with — 320x240. Streaming them in high-quality mode isn't going to help much."

Geoffrey.landis writes "It was only a small news item four months ago: all three of the Russian computers that control the International Space Station failed shortly after the Space Shuttle brought up a new solar array. But why did they fail? James Oberg, writing in IEEE Spectrum, details the detective work that led to a diagnosis." The article has good insights into the role the ISS plays as a laboratory for US-Russian technology cooperation — something that is likely to be crucial in any manned Mars mission.

Mr. E writes "Ars Technica has an interesting look at pseudoscience as it applies to homeopathy. While most discussions about what science is get derailed by the larger controversies surrounding them, Ars chose a relatively uncontroversial pseudo-science to examine so that they could examine the factors which make homeopathy a psuedo-science: ignoring settled issues in science, misapplication of real science, rejection of scientific standards, claims of suppression, large gaps between the conclusion and evidence, and a focus only on the fringes of what we currently understand."
