Delayed for years: What went wrong with New Glenn rocket? + NASA's electric airplane

INTRO: Looking every bit like a winged tube of toothpaste, NASA’s X-57 Maxwell experimental plane sits in a hangar at Edwards Air Force Base in California. The is NASA’s first crewed experimental plane in 20 years; it runs solely on electric power, an agency first, and it’s about to undergo high-voltage functional testing in advance of its first flight, scheduled for later this year...

(vehicles) Blue Origin’s massive New Glenn rocket is delayed for years. What went wrong?
https://arstechnica.com/science/2021/03/...nn-rocket/

EXCERPTS: In the fall of 2017, shortly after he became chief executive officer of Blue Origin, Bob Smith received an extensive briefing on the state of the New Glenn rocket program. The projected launch date for the massive, reusable rocket was 2020, he was told.

[...] Bezos' rocket company, of course, did not meet those projections. Not only did New Glenn not launch in 2020, last week Blue Origin said it would not launch until the fourth quarter of 2022, at the earliest. As part of its announcement, Blue Origin also did not take much blame for the rocket's delay—instead, the company blamed the delay mostly on a potential customer, the US Department of Defense. "Who does that?" asked one former employee of the company. "That excuse makes no sense."

Blue Origin's New Glenn project is incredibly ambitious. If successfully developed, it would offer a revolutionary heavy-lift service to low Earth orbit, geostationary space, and even the Moon. So what really has gone wrong?

[...] As part of his overall space strategy, Bezos has been thinking about building a large, reusable orbital rocket for a long time. Step one was to learn how to reuse rockets with the much smaller New Shepard launch system, which consists of a single-engine booster and capsule. And the company's engineers have—over the last five years, New Shepard successfully completed more than a dozen suborbital missions with picture-perfect rocket landings.

But long before New Shepard took its first flight, Bezos was already deep into planning his next rocket. [...] The "big rocket" at the time ... was not quite so big as New Glenn is envisioned today. ... Bezos originally envisioned a more modest-sized rocket comparable to the Falcon 9 or United Launch Alliance's single-stick Delta IV... [...] This would have represented a more incremental step for a launch company that has yet to put a gram of material into orbit. But instead of offering a waypoint between New Shepard and a massive orbital rocket, Bezos ultimately opted to jump right to the massive, 313-foot-tall version.

Instead of crawl-walk-run, Bezos asked his engineering team to begin sprinting toward the launch pad. The engineering challenges of building such a large rocket are big enough. But because New Glenn is so expensive to build, the company needs to recover it from the outset. SpaceX enjoyed a learning curve with the Falcon 9, only successfully recovering the first stage on the rocket's 20th launch. Blue Origin engineers will be expected to bring New Glenn back safely on its very first mission.

The decision to skip the "walk" part of the company's development has cost Blue Origin dearly, sources say. The company's engineering teams, composed of smart and talented people, are struggling with mighty technical challenges. And there are only so many lessons that can be learned from New Shepard—the smaller rocket has 110,000 pounds of thrust, and New Glenn will have very nearly 4 million.

It's not just the challenging engineering. Since Smith arrived [...] some employees have struggled with his leadership style and complained that he has acted too slowly, pushing Blue Origin to become more like a traditional aerospace company than a nimble new-space startup. But from Smith's perspective, he's trying to implement a culture transformation, from a hobby-shop atmosphere to that of a major aerospace contractor that can go out and win major NASA and Defense Department contracts. As a result, Blue Origin is now juggling a number of other major projects in addition to New Glenn... (MORE - details)
