The tallest building in California will be a 77-story ‘supertall’ skyscraper in Los Angeles

  • Los Angeles could be getting a brand-new skyscraper that’s taller than the Wilshire Grand — the tallest tower in California.
  • The planned skyscraper is 77 stories high and features a mixture of condos, hotel rooms, and commercial space.
  • The future development represents a growing trend of supertall construction as cities compete to have the most impressive skylines.

Los Angeles has endured endless criticism for its low-lying slab buildings, flat-topped towers, and mismatched design aesthetics.

In 2013, the former architecture critic at Los Angeles magazine, Greg Goldin, lamented the city’s “dull” and “mediocre” landscape.

NASA Will Flight Test a Nuclear Rocket by 2024 and Other High Tech NASA Projects

A portion of NASA’s $21.5 billion 2019 budget is for developing advanced space power and propulsion technology. NASA will spend $176 to $217 million on maturing new technology. There are projects that NASA has already been working on and others that NASA will start and try to complete. There will be propulsion, robotics, materials and other capabilities. Space technology received $926.9 million in NASA’s 2019 budget.

NASA’s space technology projects look interesting but ten times more resources devoted to advancing technological capability if the NASA budget and priorities were changed.

NASA is only spending 1 of its budget on advanced space power and propulsion technology. NASA will spend $3.5 billion in 2019 on the Space Launch System and Orion capsule. SLS will be a heavy rocket which will start off at around the SpaceX Heavy capacity and then get about the SpaceX Super Heavy Starship in payload capacity. However, the SLS will cost about $1 billion to launch each time which is about ten times more than SpaceX costs. NASA is looking at a 2021–2022 first launch and then a 2024 second launch. This would be $19+ billion from 2019–2024 to get two heavy launches and this is if there are no delays.

Check Out This Incredible X-Ray ‘Superbubble’ That’s Nearly 5,000 Light-Years Wide

This incredible image shows a pair of “nuclear superbubbles,” one over 4,900 light-years across and the other over 3,500 light-years. They’re emanating from the center of the galaxy NGC 3079, likely the result of a central black hole consuming matter and spewing it back out.

Or, the superbubbles could be from a starburst, a faster-than-usual stellar birth. The bubble-like shape could come from shock waves and compression within the cooler gas. But there’s still an element of mystery here, as the smaller bubble seems to be emanating synchrotron emission, or high-energy x-rays from spiraling electrons, while the larger bubble isn’t.
