LunaNet: Empowering Artemis with communications and navigation interoperability
With Artemis, NASA will establish a long-term presence at the Moon, opening more of the lunar surface to exploration than ever before. This growth of lunar activity will require new, more robust communications, navigation, and networking capabilities. NASA's Space Communications and Navigation (SCaN) program has developed the LunaNet architecture to meet these needs.
LunaNet will leverage innovative networking techniques, standards, and an extensible framework to rapidly expand network capabilities at the Moon. This framework will allow industry, academia, and international partners to build and operate LunaNet nodes alongside NASA. These nodes will offer missions four distinct services: networking, navigation, detection and information, and radio/optical science services.
Networking
Typically, when missions launch into space, their communication down to Earth is reliant on pre-scheduled links with either a space relay or a ground-based antenna. With multiple missions journeying to the Moon, the reliance on pre-scheduled links could limit communications opportunities and efficiencies. LunaNet offers a network approach similar to the internet on Earth, where users maintain connections with the larger network and do not need to schedule data transference in advance.

First European map of the insulating effect of forests
Paris, France (SPX) Oct 05, 2021
To cool off in summer, there's nothing better than a walk in the woods. Trees act as a buffer that cools the air beneath their foliage in summer and warms it in winter. This phenomenon is caused not only by the protection that the forest canopy provides, but also by the transpiration of trees in summer: trees absorb cooler water from the soil, and this water is then transported up to the leaves,

Rare micrometeorite may have originated from a Ceres-like asteroid
Tempe AZ (SPX) Oct 06, 2021
A micrometeorite, called TAM19B-7, may have originated from a Ceres-like asteroid, according to a recent study conducted by researchers Maitrayee Bose and Victoria Froh of Arizona State University, Martin Suttle of The Open University, U.K., and Luigi Folco, of the University of Pisa, Italy.
They will be presenting the results of their study at the 53rd annual American Astronomical Society

China's Mars probes suspend explorations due to Sun outage
Beijing (XNA) Oct 07, 2021
China's Mars rover and orbiter have suspended explorations since mid-September, to wait out a period of sun outage, the China National Space Administration said on Tuesday.
A sun outage refers to a phenomenon when Mars and the Earth move to either side of the sun and the three are almost perfectly aligned. During this period, the solar electromagnetic radiation will increase and disrupt th

Student experiments float over New Mexico
Wallops Island VA (SPX) Oct 07, 2021
University students from North and South America put their classroom knowledge and technical skills to the test when their experiments flew on a recent NASA scientific balloon flight over New Mexico.
Launched Sept. 14 from Fort Sumner, New Mexico, the balloon carried the High-Altitude Student Platform or HASP, with its 11 student experiments and also 23 student experiments through the Rock

Simulating space on Earth: NASA receives hardware for testing satellite servicing tech
Greenbelt MD (SPX) Oct 07, 2021
In August 2021, new testing equipment arrived at NASA's Goddard Space Flight Center in Greenbelt, Maryland, in the form of a gravity offset table. NASA engineers will use the table to test robotic satellite servicing technologies that will one day operate in space.
A gravity offset table is a large piece of granite used for testing space payloads in simulated zero-gravity conditions. Measu

Eutelsat raises its shareholding in OneWeb
Paris, France (SPX) Oct 07, 2021
Eutelsat Communications has exercised a call option on a portion of the latest OneWeb funding round subscribed by Bharti, for a consideration of $165 million, taking its shareholding from 17.6% to 22.9%.
The transaction was undertaken on identical financial terms to Eutelsat's initial investment of $550 million announced in April and completed on 8 September. The completion of this latest

NASA scientist looks to AI, lensing to find masses of free-floating planets
Greenbelt MD (SPX) Oct 07, 2021
Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-called rogue planets, not bound to any star. Many astronomers believe that these planets are more common than we know, but that our planet-finding techniques haven't been up to the task of locating them.

Highly porous rocks responsible for Bennu's surprisingly craggy surface
Tucson AZ (SPX) Oct 07, 2021
Scientists thought asteroid Bennu's surface would be like a sandy beach, abundant in fine sand and pebbles, which would have been perfect for collecting samples. Past telescope observations from Earth's orbit had suggested the presence of ??large swaths of fine-grain material called fine regolith that's smaller than a few centimeters.
But when the spacecraft of NASA's University of Arizona
