Amazon reportedly registers interest in bankrupt OneWeb’s broadband satellite constellation assets

Posted by in categories: Elon Musk, government, satellites

Amazon is among the players in a bankruptcy bidding game with the assets of the OneWeb satellite venture at stake, according to Space Intel Report.

Quoting unnamed industry officials, Space Intel Report’s Peter B. de Selding says other potential bidders include two Chinese organizations that are apparently acting on behalf of the Chinese government; the Paris-based satellite operator Eutelsat, which apparently has the backing of the French government and several other European Union member states; and Cerberus Capital Management, a New York-based private equity firm with interesting connections.

Surprise asteroid EVADES Earth protection satellites in one of the closest flybys ever recorded

Posted by in categories: asteroid/comet impacts, existential risks, satellites

A truck-sized asteroid has careened past Earth in one of the closest flybys ever recorded – but none of satellites scanning the skies to protect our planet saw the space rock coming.

The previously unseen asteroid, 2020 JJ, whizzed past at a distance of around 7,000 kilometers (4,350 miles) this week. In astronomical terms, that’s an incredibly close shave, and it makes it one of the closest passes of our planet ever recorded.

In a development that might worry those tasked with protecting Earth from being smashed by space objects, the asteroid was only discovered by the Mount Lemmon Survey in Arizona at almost exactly the time it reached its closest point to Earth.

SpaceX to debut satellite-dimming sunshade on next Starlink launch

Posted by in categories: Elon Musk, internet, satellites

A new sunshade, or visor, designed to reduce the brightness of SpaceX’s Starlink broadband Internet satellites will debut on the company’s next launch, a measure intended to alleviate astronomers’ concerns about impacts on observations through ground-based telescopes, SpaceX founder Elon Musk said.

Beginning with the next launch of Starlink satellites — scheduled for 18 May from Cape Canaveral — SpaceX will try out a new light-blocking panel to make the spacecraft less visible to skywatchers and astronomers.

“We have a radio-transparent foam that will deploy nearly upon the satellite being released (from the rocket),” Musk said on 27 April at a virtual meeting of the National Academies’ Decadal Survey on Astronomy and Astrophysics 2020 panel, a committee charged with setting the top priorities for US astronomy for the next decade.

‘Mars Engine’ Shatters Records for Ion Propulsion

Posted by in category: satellites

These propulsion systems already help satellites stay in position and spacecraft explore the solar system. Now engineers want to build a bigger one that could take us to Mars.

SpaceX will use sun visors to darken future Starlink satellites

Posted by in categories: internet, satellites

SpaceX has announced that it will mount a sun visor on each of its Starlink satellites and have them perform controlled maneuvers, to make them less visible to members of the astronomy community making detailed observations of the night sky. SpaceX has already launched over 400 satellites to bolster a constellation that could one day provide global broadband internet access.

The proliferation of satellite technology and the increasing affordability of reaching low-Earth orbit (LEO) has led many – particularly those in the science community – to raise concerns about the impact that space traffic may have on the night sky. This issue has only grown more contentious with the advent of the megaconstellation, which is the term used to describe vast swarms of satellites working as a network as they fly choreographed orbits through LEO space.

SpaceX’s Starlink megaconstellation is well underway to becoming a reality, and could one day provide high-speed, low latency satellite-based broadband on a global scale.

DARPA Names SEAKR Pit Boss Prime for Blackjack

Posted by in categories: engineering, military, robotics/AI, satellites

SEAKR Engineering, Inc. has been awarded as the prime contractor for Defense Advanced Research Projects Agency (DARPA) Pit Boss contract to further expand its contractual work supporting the Blackjack program. The award for Phase I Option II is part of a three-phase effort seeking on-orbit demonstration of full processing capability in a multi-satellite constellation. SEAKR was first awarded a DARPA Pit Boss contract in October 2019.

DARPA’s Blackjack program focuses on integrating commercial satellite technologies into a constellation of military satellites. As sole prime, SEAKR will continue developing it’s Pit Boss solution to support the Blackjack program’s mission as a next generation on-board processor.

SEAKR said the solution will leverage off-the-shelf electronics adapted through design implementation to function reliably in space. The company said this award validates its program success in seeking on-orbit demonstration of state-of-the-art processing capability incorporating autonomous operations, Artificial Intelligence (AI), machine learning techniques, and bridged terrestrial and on-orbit technologies.

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.
