Record-breaking laser may help test Einstein's theory of relativity
Monday, 25 January 2021 04:25Scientists have set a new record for stable laser transmission, successfully sending laser signals from one point to another without interference from the atmosphere. The record transmission was made possible by a new "phase-stabilization" technology, which utilizes free-space, self-guiding optical terminals featuring mirrors to combat interference issues like phase noise and beam wande
Designing customized "brains" for robots
Monday, 25 January 2021 04:25Contemporary robots can move quickly. "The motors are fast, and they're powerful," says Sabrina Neuman. Yet in complex situations, like interactions with people, robots often don't move quickly. "The hang up is what's going on in the robot's head," she adds. Perceiving stimuli and calculating a response takes a "boatload of computation," which limits reaction time, says Neuman, who recentl
Clocking electron movements inside an atom
Monday, 25 January 2021 04:25An international consortium of scientists, initiated by Reinhard Kienberger, Professor of Laser and X-ray Physics at the Technical University of Munich (TUM), several years ago, has made significant measurements in the femtosecond range at the U.S. Stanford Linear Accelerator Center (SLAC). However, on these miniscule timescales, it is extremely difficult to synchronize the X-ray pulse tha
Nottingham opts for IoT solution in pilot project to optimize its electric vehicle fleet
Monday, 25 January 2021 04:25The City of Nottingham is developing an intelligent energy management system (iEMS) for its Clean Mobil Energy project using OpenRemote's open-source IoT platform. This new data management solution will control the distribution of power between all system components, including a fleet of electric vehicles (EVs), battery storage and solar power. This enables the city's energy managers to ma
Project BALIS - DLR is developing and testing fuel cells in the megawatt range for air transport
Monday, 25 January 2021 04:25With its BALIS project, the German Aerospace Center (Deutsches Zentrum fur Luft- und Raumfahrt; DLR) is developing the world's first fuel cell powertrain for aircraft with an output in the megawatt range. In doing so, DLR is taking another step towards making hydrogen-powered, emission-free flight possible. Steffen Bilger, Parliamentary State Secretary at the Federal Ministry of Transport
Bridenstine joins private equity firm
Monday, 25 January 2021 02:15WASHINGTON — Less than a week after leaving the agency, former NASA Administrator Jim Bridenstine is joining a private equity firm that invests in the aerospace and defense industries.
Acorn Growth Companies, a private equity firm based in Oklahoma City, said Jan.
Space Development Agency asks industry for input on available technologies
Sunday, 24 January 2021 21:13WASHINGTON — The Pentagon’s Space Development Agency issued an open call for information from the space industry covering a laundry list of technologies.
The “broad area announcement” published Jan. 25 asks companies to submit pitches for space technology projects that the SDA might be interested in funding if they meet specific needs.
Startup Albedo focuses on 10-centimeter Earth imagery
Sunday, 24 January 2021 20:51SAN FRANCISCO – Albedo, the latest space company to join the well-known Y Combinator startup accelerator, plans to establish a satellite constellation offering Earth imagery with a resolution of 10 centimeters per pixel.
That’s the same resolution that caused a stir when former President Trump tweeted images of a heavily damaged Iranian launchpad in August 2019.
ESA’s exoplanet watcher Cheops reveals unique planetary system
Sunday, 24 January 2021 15:00ESA’s exoplanet mission Cheops has revealed a unique planetary system consisting of six exoplanets, five of which are locked in a rare rhythmic dance as they orbit their central star. The sizes and masses of the planets, however, don’t follow such an orderly pattern. This finding challenges current theories of planet formation.
Op-ed | For China, space is both substance and symbol
Sunday, 24 January 2021 14:30In December, China successfully conducted its first lunar sample retrieval mission. Chang’e-5 landed on the moon, deployed a rover who then dug up various pieces of the lunar surface, then returned to Earth with about 5 pounds of material.
Op-ed | Is public capital ready to help fuel the private space economy?
Sunday, 24 January 2021 14:11For the first time in decades, the space industry is proving to be very popular again. With the recent successes of SpaceX’s crewed missions, the upcoming landing NASA’s Mars 2020 rover, Japan’s returned sample from the asteroid Ryugu, China’s lunar landing, and the test flights of Elon Musk’s Starship, public sentiment is becoming extremely positive again and enthusiasm seems to be nearing Apollo-era heights.
In search of stable liquids
Sunday, 24 January 2021 12:05Most liquids are in suspension. Particles too small to see by naked eye swirl everywhere as gravity and temperature changes move them around. Keeping liquids from separating can be a hassle for the foods we buy in the supermarket, but also for the pharmaceutical industry seeking to extend the shelf life of medicine as long as possible.
Cloud-free crop maps foster sustainable farming
Sunday, 24 January 2021 12:00The rapidly rising global population, sustainability and climate change are among the challenges the agriculture sector faces in the business of producing food. Fortunately, information from satellites can help. A new commercial service – the first in the world – cleverly combines radar data from Copernicus Sentinel-1 and optical data from Copernicus Sentinel-2 to offer daily maps of field-scale crop biomass. Importantly, these maps are completely unimpeded by cloud cover. This new service allows farmers to better monitor and assess the growth of their produce, and, ultimately, make more effective decisions.
Phase Four launches first plasma propulsion systems
Sunday, 24 January 2021 11:34WASHINGTON — Electric propulsion company Phase Four flew its first plasma thrusters on two spacecraft that were part of a SpaceX dedicated rideshare launch Jan. 24.
Phase Four said its Maxwell plasma propulsion systems were on two of the 143 spacecraft launched on the Transporter-1 mission.
Our world is losing ice at record rate
Sunday, 24 January 2021 10:45A research team – the first to carry out a survey of global ice loss using satellite data – has discovered that the rate at which ice is disappearing across the planet is speeding up. The findings also reveal that 28 trillion tonnes of ice was lost between 1994 and 2017 – equivalent to a sheet of ice 100 metres thick covering the whole of the UK.
