Giant, continent-sized storms were observed by NASA’s Juno spacecraft.

“Thanks to the amazing increase in accuracy brought by Juno’s gravity data, we have essentially solved the issue of how Jupiter rotates: The zones and belts that we see in the atmosphere rotating at different speeds extend to about 1,900 miles (3,000 km),” Tristan Guillot, of the University of Côte d’Azur in France, said in that statement, according to LiveScience.

Nuclear power in space is still being pursued for future deep space missions…

A nuclear power plant that could provide power for long-duration crewed missions has passed another developmental milestone at NASA.

A new proof by SFI Professor David Wolpert sends a humbling message to would-be super intelligences: you can’t know everything all the time.

The proof starts by mathematically formalizing the way an “inference device,” say, a scientist armed with a supercomputer, fabulous experimental equipment, etc., can have knowledge about the state of the universe around them. Whether that scientist’s knowledge is acquired by observing their universe, controlling it, predicting what will happen next, or inferring what happened in the past, there’s a mathematical structure that restricts that knowledge. The key is that the inference device, their knowledge, and the physical variable that they (may) know something about, are all subsystems of the same universe. That coupling restricts what the device can know. In particular, Wolpert proves that there is always something that the inference device cannot predict, and something that they cannot remember, and something that they cannot observe.

“In some ways this formalism can be viewed as many different extensions of [Donald MacKay’s] statement that ‘a prediction concerning the narrator’s future cannot account for the effect of the narrator’s learning that prediction,’” Wolpert explains. “Perhaps the simplest extension is that, when we formalize [inference devices] mathematically, we notice that the same impossibility results that hold for predictions of the future—MacKay’s concern—also hold for memories of the past. Time is an arbitrary variable—it plays no role in terms of differing states of the universe.”

CAPE CANAVERAL, Fla. — NASA is sending a robotic geologist to Mars that will dig deeper than ever before.

The Mars InSight spacecraft is set to launch this weekend from California.

The lander has a slender probe designed to burrow nearly 16 feet into the Martian soil. That’s for taking the planet’s temperature. To take the planet’s pulse, a quake-measuring seismometer will operate directly on the Martian surface.

Michael Marshall attended the UK’s annual gathering of people who share the unshakeable belief that the Earth is flat.

The central role of public spaces in the social, cultural, political and economic life of cities makes it crucial that they’re accessible to everyone. One of the most important qualities of accessible public spaces is safety. If people do not feel safe in a public space, they are less likely to use it, let alone linger in it.

Perceptions of safety are socially produced and socially variable. It is not simply the presence of crime – or “threatening environments” – that contributes to lack of safety or fear.

All sorts of measures are put in place to make public spaces safer, from design to policing. But when we consider the effectiveness of these measures, we always have to ask: whose safety is being prioritised?

All good things must come to an end, and Juno— NASA’s $1-billion mission to study Jupiter like never before — is no exception. The probe launched from Earth in August 2011, reached Jupiter in July 2016, and is scheduled to make its last two of 14 high-speed flybys around the gas giant in May and July.

But that doesn’t mean Juno is finished beaming back astounding new photos of Jupiter. At least not yet but it will soon.

Berlin 26th April 2018 – The first full scale model of the European Medium-Altitude Long-Endurance Remotely Piloted Aircraft (MALE RPAS) was unveiled today during a ceremony held at the 2018 ILA Berlin Air Show, which opened its gates at Schönefeld airport.

The reveal ceremony, led by Dirk Hoke, Airbus Defence and Space Chief Executive Officer (CEO), Eric Trappier, Dassault Aviation Chairman and CEO and Lucio Valerio Cioffi, Leonardo’s Aircraft Division Managing Director, confirms the commitment of the four European States and Industrial partners to jointly develop a sovereign solution for European Defence and Security.

The unveiling of the full scale model and the reaffirmed commitment comes after a nearly two-year definition study launched in September 2016 by the four participating nations Germany, France, Italy and Spain and follows the Declaration of Intent to work together on a European MALE unmanned aerial system signed by the countries in May 2015.

As i said the other day on here. No money for science. Plenty of money for war war war. And, the knucklehead public is out zonked out to whatever mindless BS they screwing off with this minute.

In a move that shocked lunar scientists, NASA has cancelled the only robotic vehicle under development to explore the surface of the Moon, despite President Donald Trump’s vow to return people there.

Scientists working on the Resource Prospector (RP) mission, a robotic rover that had been in development for about a decade to explore a polar region of the Moon, expressed astonishment at the decision.
