Long March 5B rolled out for crewed spacecraft, space station test launch

Posted by in category: satellites

HELSINKI — China rolled out a Long March 5B launcher Wednesday for a mission to prove space station launch capabilities and test a new spacecraft for deep space human spaceflight.

Images of the Long March 5B shared on Chinese social media indicated that the rollout at Wenchang Satellite Launch Center was completed early April 29.

Launch from the coastal Wenchang launch site can now be expected around May 5. However, an official announcement has not yet been made.

Elon Musk provides more details about SpaceX’s plan to reduce Starlink satellite visibility

Posted by in categories: Elon Musk, satellites

During a virtual conference briefing this week, SpaceX founder and CEO Elon Musk provided more details about a new plan that his company has to mitigate the impact of their Starlink satellite constellation on night sky observation. Musk first revealed on Twitter the intent to build a “sun visor” to lower their visibility, but we didn’t know much about how it would work or how it compared to the test dark paint job that SpaceX tried previously.

As reported by Space News, SpaceX’s new “VisorSat” approach will essentially use sun visors to block inbound sunlight from hitting the reflective antennas on the spacecraft, stopping them from reflecting said light back to Earth, which is why they appear as bright lights in the night sky.

This new hardware addition to future Starlink satellites will supplement other measures, including making use of a new method for changing the orientation of the satellites as they raise into their target orbits after launch, which is a period during which they’re especially visible. The overall goal, according to Musk, is to “make the satellites invisible to the naked eye within a week, and to minimize the impact on astronomy,” with a specific focus on ensuring that whatever impact the constellation does have doesn’t impeded the ability of scientists and researchers to make new discoveries.

Iran launches its 1st military satellite into orbit: reports

Posted by in categories: military, satellites

Iran has apparently lofted its first military satellite into orbit, ending a series of setbacks for the nation’s space program.

A two-stage Qassed rocket lifted off from the Markazi Desert in central Iran on Wednesday (April 22) and successfully delivered a military reconnaissance satellite called Nour to orbit, Al-Jazeera reported. The rocket could be seen successfully launching into soace in this video from Iran’s Tasnim News Agency and PressTV.

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.
