Lockheed's concept moon lander can carry four astronauts

Lockheed Martin has unveiled the designs for a reusable lander built to ferry four astronauts and 1.1 tons of cargo between lunar orbit and the surface of the moon. Leveraging tech from the aerospace giant's Orion spacecraft for deep-space missions, the 14-meter, single-stage vessel can camp for up to 14 days on the moon. Upon touchdown, the crew will use the craft's lift elevator platform to get from the cabin to the surface, before blasting back to their home base aboard the Lunar Orbital Platform-Gateway -- a small space station that NASA plans to start constructing in 2022.

With enough juice to last the full two weeks, refuelling would take place between missions, though the lander can also be powered up on the surface. The preliminary concept relies on four modified RL10 engines, but other engines could also be utilized.

Lockheed's vehicle would be be twice as tall as the Lunar Module used during the Apollo missions to the Moon nearly half a century ago, reports Ars Technica, which carried two astronauts for brief stints of just a few days. The company says it will also serve as a precursor for its Mars lander -- also built to carry four people -- which is integral to its Mars Base Camp orbiting mission.

Last December, Donald Trump signed off on a space policy directive that calls for NASA, along with its private partners, to send astronauts to the Moon and, "eventually," Mars. And Lockheed is one of the private sector companies vying to be part of the exploration program. The company claims its lunar lander will be ready by the late-2020s, according to Space.com.

"The Gateway is key to full, frequent and fast reusability of this lander," said Tim Cichan, space exploration architect at Lockheed Martin Space, who presented the lander concept at the International Astronautical Congress in Bremen, Germany. "Because this lander doesn't have to endure the punishment of re-entering Earth's atmosphere, it can be re-flown many times over without needing significant and costly refurbishment. That's a major advantage of the Gateway and of a modular, flexible, reusable approach to deep space exploration."

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to...

The best air conditioner

When readers choose to buy Wirecutter's independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here . After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...
