Musk also tries to assure scientists his Starlink satellites won’t ruin the sky as many fear, and says he’d like to help send more observatories into orbit.

SpaceX to test Starlink “sun visor” to reduce brightness

Posted by in categories: Elon Musk, satellites

WASHINGTON — SpaceX Chief Executive Elon Musk said April 27 that he hopes to test a new way to reduce the brightness of the company’s Starlink satellites on the next launch for the broadband megaconstellation.

In a briefing to a committee working on the next astrophysics decadal survey, Musk said the experimental “VisorSat,” along with a new approach for orienting Starlink satellites as they raise their orbits, should address concerns raised by astronomers that the Starlink constellation could interfere with their observations.

“Our objectives, generally, are to make the satellites invisible to the naked eye within a week, and to minimize the impact on astronomy, especially so that we do not saturate observatory detectors and inhibit discoveries,” Musk said.

See a string of lights in the sky? It was probably SpaceX’s ‘Starlink’ satellites

Posted by in categories: economics, satellites

We’re getting many calls and emails from WGN viewers who say they spotted a strange string of lights crossing the night sky on Sunday.

No, it’s not planes flying in formation or a meteor shower. It’s actually a satellite string that’s part of SpaceX’s “Starlink” project. You can read more about it below.

While much of the world economy stands still, SpaceX is running full speed ahead.

Lockheed Martin wins DARPA contract to integrate Blackjack satellites

Posted by in categories: robotics/AI, satellites

WASHINGTON — The Defense Advanced Research Projects Agency awarded Lockheed Martin a $5.8 million contract for satellite integration work for the Blackjack program, the company announced April 24.

Blackjack is a project to deploy a constellation of 20 satellites in low Earth orbit by 2022 and demonstrate that a LEO system can provide global high-speed communications.

Lockheed Martin will define and manage interfaces between Blackjack’s satellite buses, payloads and the so-called Pit Boss autonomous data processor. The work will be performed at the company’s satellite manufacturing plant in Sunnyvale, California.

Elon Musk’s Internet for Everyone Is Coming Very Soon

Posted by in categories: Elon Musk, internet, satellites

Elon Musk says SpaceX’s ambitious Starlink satellite internet setup has made great steps toward providing good internet to previously low-priority locations. Musk’s Starlink plan accounts for an eventual 40,000 satellites in orbit to blanket the globe in internet coverage, far surpassing any existing satellite internet service.

China reveals name, logo for its ‘Tianwen’ first Mars landing mission

Posted by in categories: robotics/AI, satellites

— China revealed the name and logo for its first mission aimed at landing on the planet Mars to mark the 50th anniversary of its first satellite launch.

Celebrating the country’s Space Day on Friday (April 24), the China National Space Administration (CNSA) announced that its upcoming robotic mission to the Red Planet will be named “Tianwen-1.” The name, borrowed from an ancient Chinese verse by poet Qu Yuan, translates to “questions about the heavens.”

“In ‘Tianwen,’ Qu Yuan raised a series of questions in verse involving the sky, stars, natural phenomena, myths and the real world, showing his doubts about some traditional concepts and the spirit of seeking the truth,” reported the state-run Chinese news service Xinhua.

Elon Musk says Starlink internet private beta to begin in roughly three months, public beta in six

Posted by in categories: Elon Musk, internet, satellites

SpaceX CEO and founder Elon Musk has shared more details about when in 2020 we can expect the company’s Starlink low-latency, high-bandwidth satellite internet service to actually be available to customers. He said on Twitter that a private beta for Starlink would begin in around three months, with a public beta to kick off roughly three months after that.

The initial beta test will apply to those located in “high latitudes,” Musk added. To date, SpaceX has said that Starlink service will initially be made available to customers in Canada and in the northern United States in 2020, with additional service expansion to follow to other parts of the world throughout 2021. On Twitter in response to a question about whether Germany counts as “high latitude,” Musk said that it does, indicating beta service at least may be available in more markets than the U.S. and Canada ahead of next year.

Late last year, Musk tweeted saying he was using a Starlink satellite connection to do so, and since then the company has launched six batches of 60 satellites each to build out its network. The small satellites work by flying around the Earth in low orbit, passing off connection between one another to ensure consistent service is provided to ground stations. They orbit lower than geostationary communications satellites, which provides latency and speed benefits, but don’t remain in a fixed position so a large number of them are required to provide consistent connectivity.

Scientists compile the first comprehensive geological map of the Moon

Posted by in category: satellites

Drawing on data from satellites and Apollo-era missions, scientists at the US Geological Survey (USGS), NASA and the Lunar Planetary Institute have pieced together what they say is the first comprehensive geological map of the Moon.

Our 4.5-billion-year-old satellite is adorned with all kinds of rocks, craters and other interesting geological features. To dig into the details, the scientists looked to regional maps from six Apollo missions and combined these with modern data from recent satellite missions.

Refreshing the historical maps with fresh scientific observations enabled the scientists to put together an incredibly detailed perspective of the Moon, showing its geology at a scale of 1:5,000,000.

SpaceX’s Starlink network surpasses 400-satellite mark after successful launch

Posted by in categories: futurism, satellites

After years of studies, test-firings and a survey of U.S. industry in preparation for launch of a Mars Sample Return mission in 2026, NASA has settled on a solid-fueled design for a miniature rocket with a first-of-its-kind purpose: Launching a payload from Mars for a trip back to Earth.

The small launcher is called a Mars Ascent Vehicle, or MAV. The MAV will play a key role in the Mars Sample Return mission being developed by NASA and the European Space Agency.
