Boeing, the world’s second-largest defense firm, has detailed the hardware it thinks humanity will need to stage a piloted mission to Mars — and outlined plans for lunar bases, which will serve as a jumping off point for deep space missions, and assist in exploration of the Moon.

Boeing, and five other companies, are already collaborating with NASA to develop the Space Launch System (SLS), which it is hoped will power a trip to Mars. Now, the firm has offered up conceptual designs for other accessories it will be useful for the mission, and a more general vision of how it could be achieved — and made easier on repeat visits. Of particular note are a deep space habitat design, and transport vehicle.

Sometimes people bring up overpopulation scenarios where the population can fit inside Texas. But they ask, what about all the stuff that supports that population? Here is one answer.

Located in an abandoned 70,000-square-foot factory in Newark, New Jersey, the world’s largest vertical farm aims to produce 2,000,000 pounds of food per year. This AeroFarms operation is also set up to use 95% less water than open fields, with yields 75 times higher per square foot. Their stacked, high-efficiency aeroponics system needs no sunlight, soil or pesticides. The farm’s proximity to New York City means lower transportation costs and fresher goods to a local market. It also means new jobs for a former industrial district.

Depression, anxiety, grief, despair, stress—even suicide: The damage of unfolding climate change isn’t only counted in water shortages and wildfires, it’s likely eroding mental health on a mass scale, too, reports the American Psychological Association, the preeminent organization of American mental health professionals.

Direct, acute experience with a changing climate—the trauma of losing a home or a loved one to a flood or hurricane, for example—can bring mental health consequences that are sudden and severe. After Hurricane Katrina, for example, suicide and suicidal ideation among residents of areas affected by the disaster more than doubled according to a paper led by Harvard Medical School, while one in six met the criteria for PTSD, according to a Columbia University-led paper. Elevated PTSD levels have also been found among people who live through wildfires and extreme storms, sometimes lasting several years.

But slower disasters like the “unrelenting day-by-day despair” of a prolonged drought, or more insidious changes like food shortages, rising sea levels, and the gradual loss of natural environments, will “cause some of the most resounding chronic psychological consequences,” the APA writes in its 69-page review of existing scientific literature, co-authored by Climate for Health and EcoAmerica, both environmental organizations. “Gradual, long-term changes in climate can also surface a number of different emotions, including fear, anger, feelings of powerlessness, or exhaustion.”

EVER since ENIAC, the first computer that could be operated by a single person, began flashing its ring counters in 1946, human beings and calculating machines have been on a steady march towards tighter integration. Computers entered homes in the 1980s, then migrated onto laps, into pockets and around wrists. In the laboratory, computation has found its way onto molars and into eyeballs. The logical conclusion of all this is that computers will, one day, enter the brain.

This, at least, is the bet behind a company called Neuralink, just started by Elon Musk, a serial technological entrepreneur. Information about Neuralink is sparse, but trademark filings state that it will make invasive devices for treating or diagnosing neurological ailments. Mr Musk clearly has bigger plans, though. He has often tweeted cryptic messages referring to “neural lace”, a science-fictional concept invented by Iain M. Banks, a novelist, that is, in essence, a machine interface woven into the brain.

The future is here, and it’s transparent tech.

A webpage today is often the sum of many different components. A user’s home page on a social-networking site, for instance, might display the latest posts from the users’ friends; the associated images, links, and comments; notifications of pending messages and comments on the user’s own posts; a list of events; a list of topics currently driving online discussions; a list of games, some of which are flagged to indicate that it’s the user’s turn; and of course the all-important ads, which the site depends on for revenues.

With increasing frequency, each of those components is handled by a different program running on a different server in the website’s data center. That reduces processing time, but it exacerbates another problem: the equitable allocation of network bandwidth among programs.

Many websites aggregate all of a page’s components before shipping them to the user. So if just one program has been allocated too little bandwidth on the data center network, the rest of the page—and the user—could be stuck waiting for its component.

In a bid to get around terrestrial height restrictions, Clouds Architecture Office has proposed suspending the world’s tallest skyscraper from an asteroid, leaving residents to parachute to earth.

New York-based Clouds Architecture Office drew up plans for Analemma Tower to “overturn the established skyscraper typology” by building not up from the ground but down from the sky by affixing the foundations to an orbiting asteroid.

“Harnessing the power of planetary design thinking, it taps into the desire for extreme height, seclusion and constant mobility,” said the architects, who have previously drawn up proposals for space transportation and a 3D-printed ice house on Mars.

Maybe the only way isn’t up after all: newly released concept drawings by a Greek architect for a skyscraper in Manhattan bend more than just minds.

According to architect Ioannis Oikonomou, New York’s zoning laws are prompting developers to explore new ways to maximize a building’s height. To that end, his studio is exploring substituting height with length.

Apart from being a novel addition to Manhattan’s impressive skyline, the structure — dubbed The Beg Bend — could essentially become a viable architectural solution that addresses the height limitations of buildings in the city. It could even be an answer to the city’s expensive housing — giving the building the prestige of a high-rise while maximizing the limited space.

More than four years ago, I covered the issue of cislunar planning here (see “The cislunar gateway with no gate”, The Space Review, October 1, 2012). Now the same “gateless” base concept has returned, but this time, it is not the only concept on the table. Currently there seem to be a plethora of achievable cislunar and lunar concepts, but few people seem to understand what makes any of them practical and affordable. Multiple reusable launchers, in-space vehicles, and components are being developed or have recently been announced, including the New Glenn, the Blue Moon lunar lander, SpaceX’s gigantic Interplanetary Transport System with its still unnamed booster. In addition, there are various lunar orbit combination habitats and depots proposed by Bigelow and the previously announced vehicles and concepts such as the Falcon Heavy, the XEUS lander, and the Cryote depot concept.

Operational plans that only include cislunar bases are being proposed, as well as plans which call for only lunar surface bases to be supplied directly from the Earth, in addition to the more modern, cislunar resource-supported lunar base scenarios. These plans and designs are all like pieces of a very important jigsaw puzzle, but one that, due to the current circumstances, forces us to start with the individual pieces, instead of a whole original image. Our mission, if we can manage it (politically, fiscally and technically), is to try to create a functional whole—a cislunar transportation system —out of some or most of these pieces.

As the obvious and practical location for a gateway to the Moon, Mars, and the asteroids, a cislunar logistics base is the first component we need in place. I am not as concerned about which orbit any cislunar station is placed in compared to the base components, but it is still clear that the Earth Moon L1 point has an advantage since it is always in the same general area, and can be reached from any location on the moon in about 12 hours at any time without waiting for an orbital position to match. A station placed in the “near-rectilinear (lunar) halo orbit” (NRHO) proposed recently would actually be in a high, elliptical, lunar polar orbit (HELPO) that takes more propellant and time to reach from or to than most other options. The best orbits to support lunar operations have a short and relatively unchanging transit time from or to the lunar surface, a lower delta-V per trip, and which can be reached from most places on the surface at almost any time.
