Two small satellites launched last summer by the Defense Advanced Research Projects Agency successfully established an optical link on April 14 during a nearly 40-minute test, according to CACI International, the supplier of the optical terminals.
More than 200 gigabits of data were transmitted and received over a distance of about 100 kilometers, the company said May 17. Optical terminals use lasers to connect satellites in orbit so they can transfer data in space.
DARPA’s experiment called Mandrake 2 was funded by the Space Development Agency and the Air Force Research Laboratory. The success of the demonstration is significant as space-to-space optical communications is a critical technology for DARPA’s Blackjack constellation and for SDA’s planned mesh network of small satellites in low Earth orbit that will support military operations. »
Earlier this week, the National Highway Traffic Safety Administration (NHTSA) released the latest road fatality statistics. It is “grim reading,” the latter being a phrase that regularly appears in news articles about American road death statistics for the past half-century. 42,915 people died while trying to get where they needed to go on U.S. roads last year. That’s 117 people on average each day, or about the number of people you can stuff into a large regional jet. One plane going down every day for an entire year.
It’s unclear why Ohio leads all other states in boosting Ontario’s supply of crime guns. Experts say it could be the lack of specific laws regulating private sales of firearms and proximity to Canada.
But whether it’s Michigan, Ohio, Florida, Georgia, one connection between these five states is a major highway: the I-75, which runs from the tip of Florida up to the Great Lakes. Investigators said they are still investigating why Texas has become a top source state.
“There’s obviously a possibility that guns are coming up from those states through the I-75 corridor and right into the underbelly of Ontario,” ATF agent Taylor said. »
The Arctic is warming up faster than the rest of our planet, causing sea ice to melt and altering ecosystems and life in the region. Satellite data is essential in monitoring those changes. Enhanced data sharing is a new tool in our collective arsenal to confront #ClimateChange. pic.twitter.com/oqXmKuucB6
