NASA Extends Deep Space Atomic Clock Mission

Posted by in categories: mobile phones, robotics/AI, satellites

Smart phone apps provide nearly instantaneous navigation on Earth; the Deep Space Atomic Clock could do the same for future robotic and human explorers.

As the time when NASA will begin sending humans back to the Moon draws closer, crewed trips to Mars are an enticing next step. But future space explorers will need new tools when traveling to such distant destinations. The Deep Space Atomic Clock mission is testing a new navigation technology that could be used by both human and robotic explorers making their way around the Red Planet and other deep space destinations.

In less than a year of operations, the mission has passed its primary goal to become one of the most stable clocks to ever fly in space; it is now at least 10 times more stable than atomic clocks flown on GPS satellites. In order to keep testing the system, NASA has extended the mission through August 2021. The team will use the additional mission time to continue to improve the clock’s stability, with a goal of becoming 50 times more stable than GPS atomic clocks.

Crews create a blast to take the Deep Underground Neutrino Experiment to the next stage

Posted by in categories: particle physics, space

It started with a blast.

On June 23, construction company Kiewit Alberici Joint Venture set off explosives 3,650 feet beneath the surface in Lead, South Dakota, to begin creating space for the international Deep Underground Neutrino Experiment, hosted by the Department of Energy’s Fermilab.

The blast is the start of underground activity for the experiment, known as DUNE, and the infrastructure that powers and houses it, called the Long-Baseline Neutrino Facility, or LBNF.

CERN experiment makes first observation of rare events producing three massive force carriers

Posted by in categories: cosmology, particle physics

Modern physics knows a great deal about how the universe works, from the grand scale of galaxies down to the infinitesimally small size of quarks and gluons. Still, the answers to some major mysteries, such as the nature of dark matter and origin of gravity, have remained out of reach.

Caltech physicists and their colleagues using the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, the largest and most powerful particle accelerator in existence, and its Compact Muon Solenoid (CMS) experiment have made a new observation of very that could help take physics beyond its current understanding of the world.

The new observation involves the simultaneous production of three W or Z bosons, subatomic “mediator particles” that carry the weak force—one of the four known —which is responsible for the phenomenon of radioactivity as well as an essential ingredient in the sun’s thermonuclear processes.

Researchers create easy-to-use math-aware search interface

Posted by in categories: computing, mathematics

Researchers at Rochester Institute of Technology have developed MathDeck, an online search interface that allows anyone to easily create, edit and lookup sophisticated math formulas on the computer.

Created by an interdisciplinary team of more than a dozen faculty and students, MathDeck aims to make notation interactive and easily shareable, rather than an obstacle to mathematical study and exploration. The math-aware interface is free to the public and available to use at mathdeck.cs.rit.edu.

Researchers said the project stems from a growing public interest in being able to do web searches with math keywords and formulas. However, for many people, it can be difficult to accurately express sophisticated math without an understanding of the scientific markup language LaTeX.

Elon Musk hints at Tesla Cybertruck being amphibious — is he kidding?

Posted by in categories: Elon Musk, space travel, sustainability

Elon Musk is hinting at Tesla Cybertruck being virtually amphibious, and it’s not clear if he’s actually kidding.

Sometimes, Musk makes comments about future Tesla products and features that can be hard to judge.

For example, it was hard to tell if he was kidding when he said that the next Tesla Roadster would be equipped with a cold air thruster, but that’s apparently happening.

New study reveals how metamorphosis has shaped the evolution of salamanders

Posted by in categories: education, evolution

A team of scientists, led by Natural History Museum postdoctoral researcher Dr. Anne-Claire Fabre, have conducted the first study on how metamorphosis has influenced the evolution of salamanders.

Using micro-CT scanning to study the skulls of this group of animals, the team were able to build a huge dataset of 148 species of and used cutting-edge methods to describe the shape of the with nearly 1000 reference points, known as landmarks.

Dr. Fabre said, “Most studies of this kind are limited to just a few dozen landmarks. Our study is the first large-scale investigation of this incredibly diverse group. We have captured the shape of the skull in such great detail that it has allowed us to learn more than ever before about how these creatures evolved.”

Electricity transmission reaches even higher intensities

Posted by in categories: energy, physics

Intensity is rising at CERN. In the superconducting equipment testing hall, an innovative transmission line has set a new record for the transport of electricity. The link, which is 60 metres long, has transported a total of 54 000 amperes (54 kA, or 27 kA in either direction). “It is the most powerful electrical transmission line built and operated to date!” says Amalia Ballarino, the designer and project leader.

The line has been developed for the High-Luminosity LHC (HL-LHC), the accelerator that will succeed the Large Hadron Collider (LHC) and is scheduled to start up at the end of 2027. Links like this one will connect the HL-LHC’s magnets to the power converters that supply them.

The secret to the new line’s power can be summarised in one word: superconductivity.

NASA ready to buy suborbital rides for its people. This week, NASA formally asked the US space industry to dish the details on its plans for brief spaceflights. In essence, the space agency said it wants to buy brief hops into space for its Astronaut Corps and scientists, but it needs more information, Ars reports. NASA Administrator Jim Bridenstine said the program seeks mostly to increase the time NASA spends in microgravity.

Balancing cost and risk … The biggest question concerns the risk that NASA is willing to accept in putting its people on these space vehicles. For the space shuttle program, NASA had complete oversight of the vehicle’s development. Although the commercial crew program was a public-private partnership, NASA still had significant insight into every facet of SpaceX’s Crew Dragon and Boeing’s Starliner spacecraft because it paid for most of the development costs. Now, NASA is solely a customer. “We’re not going to make it more dangerous than orbital flight,” Bridenstine said of suborbital flight.
