Over the past decade and a half, satellites the size of a toaster have opened up new possibilities for using space. Called CubeSats, these diminutive spacecraft offer several appealing virtues for scientific and national security missions. They have one major handicap — but a fix is on the way.

For all their advantages, CubeSats are hamstrung by one shortcoming: they lack their own rocket motor. To solve the problem, scientists at Los Alamos National Laboratory, which has a long history of developing propellants as part of the nuclear weapons program, have developed a unique segregated fuel oxidizer rocket fuel system.

For all their power, supercomputers require specialized software and applications, which makes it difficult for users running big data analyses – which comes with its own set of frameworks and dependencies -- to take advantage of the hardware.

To make it easier for researchers working with big data to use supercomputers, developers at Los Alamos National Laboratory have created a program called “Charliecloud” that uses a container approach to lets users package their own software stacks. (Full Story)



Entropy: a shot in the arm for IoT security?

Entropy engine hardware, LANL photo.

With machine intelligence and massive cloud-driven compute power at our disposal, it is becoming easier and easier to ‘guess’ the codes that underpin encryption and crypto-based applications. Thus, entropy is needed.

In terms of mathematics, entropy is a lack of order or predictability and a gradual decline into a state of numerical disorder.

The technology is born out of a decade-long research project conducted by the quantum security team at the Los Alamos National Laboratory and is designed to strengthen cryptographic security systems from encryption in traditional datacenters and virtual cloud environments. (Full Story)

supercomputer use. LANL photo.

At Los Alamos National Laboratory, home to more than 100 supercomputers since the dawn of the computing era, elegance and simplicity of programming are highly valued but not always achieved. In the case of a new product, dubbed "Charliecloud," a crisp 800-line code helps supercomputer users operate in the high-performance world of Big Data without burdening computer center staff with the peculiarities of their particular software needs. "Charliecloud lets users easily run crazy new things on our supercomputers," said lead developer Reid Priedhorsky of the High Performance Computing Division at Los Alamos. (Full story)

Using data from the Mars Science Laboratory “Curiosity” rover, the group at Los Alamos National Laboratory in Los Alamos, New Mexico, was able to determine that Gale Crater once contained a lake of water that was likely drinkable. Moreover, even after the surface water of the lake disappeared, a significant amount of remained beneath the surface, and for a much longer period of time than previously understood.

“What this finding tells us is that, even when the lake eventually evaporated, substantial amounts of groundwater were present for much longer than we previously thought – thus further expanding the window for when life might have existed on Mars,” said Jens Frydenvang. (Full story)

'Halos' on Mars suggest conditions for life lasted longer than thought

Mars Curiosity Rover, NASA image.

Shortly after touching down inside the Red Planet's 96-mile-wide (154 kilometers) Gale Crater in August 2012, NASA's Curiosity rover found evidence that the area had harbored a potentially habitable lake-and-stream system in the ancient past.

"This tells us that the silica found in halos in younger rocks close by was likely remobilized from the old sedimentary rocks by water flowing through the fractures," said study lead author Jens Frydenvang, a scientist at Los Alamos National Laboratory. (Full Story)



Curiosity finds new evidence of long-term groundwater on Mars

Pale zones called halos border bedrock fractures visible in this 2015 NASA image.

Curiosity, our most advanced robotic explorer on Mars, is currently roving around the Gale crater, taking samples and analyzing the composition of crater material. The trusty bot previously revealed that Gale crater was likely once an enormous lake that stretched for miles "with water that we would even have been able to drink," said Jens Frydenvang, a rover-team scientist at Los Alamos National Laboratory and the University of Copenhagen.

Neutron lifetime measurements take new shape for in situ detection

Pouring ultra-cold neutrons into a Helium-3 counter.

Measurements of the neutron lifetime and accurate simulations of Big Bang Nucleosynthesis (BBN) require old neutrons to be freed from their nuclear cages. Christopher Morris of Los Alamos National Laboratory and author of the new study explained that neutrons have been essentially "fossilized" in the nuclei of atoms. Studying these "fossil particles," then, can provide a glimpse of the earliest moments of the universe's existence.

By the time BBN ended, most neutrons were locked up in the nuclei of helium atoms. Today, almost all matter in the universe is still close to the initial delicate ratio of helium to hydrogen. The ratio is important since it determines how fast our sun burns hydrogen, powering life on earth. (Full Story)
