An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath.
The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured. It could be used as insulation within aircraft engines to reduce noise by up to 16 decibels - reducing the Juice in Large Space Simulator

Space Force, DoD agencies planning multi-orbit sensor network to track hypersonic missiles
Monday, 21 June 2021 23:08 Write a comment
WASHINGTON — The U.S. Space Force last month selected Millennium Space Systems and Raytheon to design sensors that can track hypersonic missiles from medium Earth orbit.
If successful, sensors in medium orbits could become a new addition to the United States’ layered missile defense system that currently includes ground, sea-based and space sensors.

Take 2: Spacewalking astronauts install new solar panel
Sunday, 20 June 2021 19:26 Write a comment
Spacewalking astronauts equipped the International Space Station with the first in a series of powerful new solar panels Sunday, overcoming suit problems and other obstacles with muscle and persistence.
It took two spacewalks for French astronaut Thomas Pesquet and NASA astronaut Shane Kimbrough to install and unfurl the panel to its full 63 feet (19 meters) in length.
The solar wing unrolled like a red carpet once the final set of bolts was released, relying solely on pent-up energy. The slow but steady extension took 10 minutes, with station cameras providing live TV views.
"It is beautiful," Pesquet called out.
"Well done, both of you," Mission Control replied once the operation was complete.

WASHINGTON — A NASA-funded smallsat mission to Mars that lost its ride last year may get new life through a partnership with Rocket Lab.
Rocket Lab announced June 15 it won a contract from the Space Sciences Laboratory (SSL) of the University of California Berkeley to begin design work on a new version of the Escape and Plasma Acceleration and Dynamics Explorers (EscaPADE) mission to Mars.
Novel chirped pulses defy 'conventional wisdom'
Sunday, 20 June 2021 01:59 Write a comment
The 2018 Nobel Prize in Physics was shared by researchers who pioneered a technique to create ultrashort, yet extremely high-energy laser pulses at the University of Rochester.
Now researchers at the University's Institute of Optics have produced those same high-powered pulses - known as chirped pulses - in a way that works even with relatively low-quality, inexpensive equipment. The new w Lockheed Martin-Built Next Generation GPS III Satellite Propels Itself to Orbit
