The New Normal Is Digital Cities — Not Smart Cities

Posted by in category: space

New “space as a service” initiatives are evolving. As a result of WeWork pulling its IPO, I expect you will see renegotiated leases and direct competition across the globe, with a $3 billion fund to start. Real estate development is moving in two directions — technology and experience — but firms need to figure out what that means for them, and how to spend their money.

Delete Technology, Add Humans

Many smart city projects have not met their goals. IoT may make some efficiency gains, but it doesn’t automatically improve quality of life or reduce complexity. City planners and real estate developers need to take a longer view and understand that ROI is directly tied to the GDP of the area.

Is the universe controlled by gigantic structures?

The idea that celestial objects exist within utterly immense cosmic structures is becoming inescapable.

Cheers! Alcoholic beverages in space

Posted by in categories: food, life extension, space

On November 2, 12 bottles of Bordeaux wine were launched to the International Space Station (ISS). These bottles are not intended for holiday celebrations by the crew, however (consumption of alcohol is officially prohibited in space.) Instead. the bottles are part of an experiment conducted by the University of Bordeaux’s Institute of Vine and Wine Science (ISVV) and a company called Space Cargo Unlimited to investigate if the aging process of wine is affected by microgravity conditions.

As novel as this experiment sounds, the Bordeaux team is not the first group to examine how alcoholic beverages age in space. That distinction is held by two whisky producers, one in Scotland, the other in Japan. In 2011, Scotch whisky producer Ardbeg partnered with Nanoracks to launch the first whisky aging experiment in orbit. When the samples were returned to Earth in 2014, a clear difference was readily apparent from the control samples that remained on Earth—and not for the better. According to an Ardbeg white paper, the aftertaste was “pungent, intense and long, with hints of wood, antiseptic lozenges and rubbery smoke.” However, Ardbeg was not certain if this was a result of the aging process or other extreme factors that the samples encountered.

In 2015, Japanese whisky producer Suntory also launched whisky samples to be aged on the ISS. One batch of these samples returned to Earth for analysis after a year in orbit, but another batch still remains on the station. Thus far, Suntory has not released any data from these experiments.

China’s Mars ambitions one step closer after successful test of lander

Posted by in categories: robotics/AI, space

China has completed its first public test of a Mars lander, keeping the country on track for an unmanned exploration mission to the red planet in 2020.

The trial took place Thursday in the mountainous landscape of Hebei province, about an hour and a half drive north of Beijing. Chinese officials said the landscape mirrored the slopes and craters of the planet Mars.

New Lasers May Be Powerful Enough to Drill a Hole in Reality

Posted by in categories: physics, space

The prestigious academic physics journal Physical Review Letters published a paper this week about cutting-edge laser tech — and, if bloggers are to be believed, it could have juicy ramifications.

The paper itself is dry and technical, but the prominent tech blog Ars Technica’s interpretation of its findings is anything but. According to Ars, in fact, the tech it describes could pulse a laser “through fabric of the Universe.”

The Moon’s violent origin

Posted by in category: space

From remote measurements of the Moon’s mass and radius, researchers also know its density is anomalously low, indicating it lacks iron. While about 30 percent of Earth’s mass is trapped in its iron-rich core, the Moon’s core accounts for only a few percent of its total mass. Despite this substantial difference in iron, Apollo samples later revealed that mantle rocks from the Moon and Earth have remarkably similar concentrations of oxygen.

And because these lunar and terrestrial rocks differ significantly from meteorites originating from Mars or the asteroid belt, it shows the Moon and Earth’s mantle share a past connection. Additionally, compared with Earth, lunar rocks are more depleted in so-called volatile elements — those that vaporize easily upon heating — which hints that the Moon formed at high temperatures.

Finally, researchers know that tidal interactions forced the Moon to spiral outward over time, which in turn caused Earth to spin more slowly. This implies the Moon formed much closer to Earth than it is now. Precise measurements of the Moon’s position using surface reflectors placed during the Apollo program subsequently confirmed this, verifying the Moon’s orbit expands by about 1.5 inches (3.8 centimeters) each year.

Ejected Star: How fast is fast?

The fastest man-made object pales in comparison to a Hills ejection

Earlier today, Genevieve O’Hagan updated Lifeboat readers on this week’s momentous event in Astronomy. At least, I find it fascinating—and so, I wish to add perspective…

30 years ago, astronomer Jack Hills demonstrated the math behind what has become known as the “Hills Mechanism”. Until this week, the event that he described had never been observed.* But his peer astronomers agreed that the physics and math should make it possible…

Hills explained that under these conditions, a star might be accelerated to incredible speeds — and might be even flung out of its galaxy:

  • Suppose that a binary star passes close to a black hole, like the one at the center of our galaxy
  • The pair of self-orbiting stars is caught up in the gravity well of a black hole, but not sucked in

If conditions are right, one star ends up orbiting the back hole while the other is jettisoned at incredible speed, yet holding onto its mass and shape. All that energy comes from the gravity of the black hole and the former momentum of the captured star. [20 sec animation] [continue below]

Curiosity rover reveals “mind-boggling” oxygen swings on Mars

Posted by in category: space

The study of Mars is a constant exercise in problem-solving, and NASA scientists have just been served up a doozy. Data from the Curiosity rover positioned within the planet’s Gale Crater has revealed wild seasonal swings in oxygen levels, something mission scientists neither expected or are able to explain.

This perplexing piece of intel comes courtesy of Curiosity’s Sample Analysis at Mars (SAM) tool, an onboard laboratory that has been sucking in the air over the Gale Crater for analysis over the course of three Martian years (almost six Earth years). This has enabled the team to piece together the composition of the planet’s thin atmosphere, with CO2, nitrogen, argon, carbon monoxide and oxygen all part of the mix.

The concentrations of these gases increase and decrease as the weather changes on Mars, as the icy winters lower air pressure across the planet and the summer then raises them again. This leads to regular patterns of concentrations of gases like nitrogen and argon, and in examining the latest data, the scientists expected to see similar trends at play for oxygen.
