SpaceX is in the process of building its Starlink broadband internet network that will offer service worldwide to fund future missions to the moon and Mars. The aerospace company has been deploying internet-beaming Starlink satellites into low Earth orbit. As of today, there is a total of 540 satellites in space, out of the 12,000 SpaceX plans to deploy. The next deployment of 57 satellites is scheduled for this month [date pending]. Company officials said 800 satellites will offer “moderate” internet coverage; 60 Starlink satellites can provide service to 40,000 customers streaming high-definition videos simultaneously. “With performance that far surpasses that of traditional satellite internet, and a global network unbounded by ground infrastructure limitations, Starlink will deliver high-speed broadband internet to locations where access has been unreliable, expensive, or completely unavailable,” the company website states.

SpaceX has successfully recovered two pairs of Falcon 9 payload fairings (nosecones) – one twice-flown – in one month after twin ships GO Ms. Tree and GO Ms. Chief returned to port on July 2nd.

Around 45 minutes after Falcon 9 B1060 lifted off for the first time with the US military’s third upgraded GPS III satellite in tow and around 40 minutes after the rocket’s payload fairing deployed, both fairing halves gently splashed down in the Atlantic Ocean just a few miles apart. Lacking their main recovery nets in an odd configuration, Ms. Tree and Ms. Chief both fished one half out of the ocean with smaller secondary nets before placing the fairings on their decks for technicians to secure them.

A little more than two weeks prior, both ships were in the midst of recovering the Starlink-8 mission’s twice-flown fairings from the ocean, safely returning them – intact – to shore for the first time since SpaceX began fairing reuse. As SpaceX itself noted at the tail end of its GPS III SV03 webcast, the intact recovery of the mission’s fairing halves all but guarantees that they’ll be reused in the near future.

A team of astronomers from Harvard and other institutions are collaborating on a new project to scan the skies for technological signatures from alien civilizations.

It’s a noteworthy new project, as it’s the first to receive a NASA grant for SETI-specific research in more than 30 years, according to a statement.

“Technosignatures relate to signatures of advanced alien technologies similar to, or perhaps more sophisticated than, what we possess,” said Avi Loeb, the chair of the Harvard astronomy department Harvard, in a statement. “Such signatures might include industrial pollution of atmospheres, city lights, photovoltaic cells (solar panels), megastructures, or swarms of satellites.”
