Satellites and light reflections help spot coastal plastic waste
Millions of tons of plastic enter the oceans every year. While stopping this flow is crucial, so is tracking down what's already there so we can clean it up.
This cutting-edge research harnesses the latest in satellite technology to do just that.
The study, now published in Remote Sensing, used the unique infrared signals reflected by plastics to identify even tiny scraps amongst vas New lightweight material is stronger than steel
Using a novel polymerization process, MIT chemical engineers have created a new material that is stronger than steel and as light as plastic, and can be easily manufactured in large quantities.
The new material is a two-dimensional polymer that self-assembles into sheets, unlike all other polymers, which form one-dimensional, spaghetti-like chains. Until now, scientists had believed it was Persistence, encouragement, innovation keeps NASA's DAVINCI on track
The concept of a NASA-led Venus deep atmosphere chemistry probe was developed and evolved over more than a decade. Through multiple mission bids starting in 2008, rejections and tailored re-designs, a team of scientists and engineers finally prevailed with the selection of the Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging, or DAVINCI mission in June 2021.
Among Dozens of Starlink satellites from latest launch to reenter after geomagnetic storm
Up to 80% of the Starlink satellites launched by SpaceX last week will soon reenter, or have already done so, because a geomagnetic storm kept the spacecraft from raising their orbits.

China plans more than 50 space launches in 2022
China’s main space contractor aims to launch at least 140 spacecraft across more than 50 launches in 2022 following its busiest year in space so far.
SpaceX satellites falling out of orbit after solar storm
Dozens of SpaceX internet satellites lost to geomagnetic storm
Up to 40 SpaceX high-speed internet satellites have been knocked out of orbit by a geomagnetic storm shortly after launch, but pose little threat to Earth as they burn up in the atmosphere, the company said.
Geomagnetic storms are caused by ejections of the solar corona into space, resulting in disturbances to the Earth's upper atmosphere and increased drag on objects in low orbits.
The Viasat adds polar coverage to ground station-as-a-service business
Viasat plans to deploy an antenna in Sweden in April to give its ground station-as-a-service business polar coverage for the first time, the California-based satellite operator said Feb. 9.

Increasing production is important for Hypersonics, Defense official says
The Defense Department is working hard on developing both hypersonic offensive and defensive capabilities. But in the immediate future, one of the most important areas to be developed is increasing the capacity at which such systems can be produced, said Gillian Bussey, director of the Joint Hypersonics Transition Office.
"I would say that everything we're doing in terms of the interceptor
