WASHINGTON — The Defense Advanced Research Projects Agency plans to launch the first experimental satellites of the Blackjack program in late 2020 and early 2021, the agency said May 11.
DARPA’s Tactical Technology Office started the Blackjack program in 2018 to show the military utility of low Earth orbit constellations and mesh networks of low-cost satellites.
As many as 20 satellites will be launched by 2022.
The U.S. space agency National Aeronautics Space Administration (NASA), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are inviting coders, entrepreneurs, scientists, designers, storytellers, makers, builders, artists, and technologists to participate in a virtual hackathon May 30–31 dedicated to putting open data to work in developing solutions to issues related to the COVID-19 pandemic.
During the global Space Apps COVID-19 Challenge, participants from around the world will create virtual teams that – during a 48-hour period – will use Earth observation data to propose solutions to COVID-19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May.
“There’s a tremendous need for our collective ingenuity right now,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “I can’t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions.”
The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system – on global to local scales – with aspects of the COVID-19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the virus.
The next flight of the U.S. military’s reusable X-37B spaceplane — scheduled for liftoff May 16 from Cape Canaveral — will carry more experiments into orbit than any of the winged ship’s previous missions, including two payloads for NASA and a small deployable satellite built by Air Force Academy cadets.
Military officials announced new details about the upcoming X-37B mission Wednesday, and confirmed its target launch date of May 16. The Boeing-built spaceplane was mounted on top of a United Launch Alliance Atlas 5 rocket Tuesday inside the Vertical Integration Facility at Cape Canaveral’s Complex 41 launch pad.
The unpiloted spacecraft launches inside a payload shroud on top of a conventional rocket, unfurls a power-generating solar array in orbit to generate electricity, and returns to Earth for a runway landing like NASA’s retired space shuttle.
In 2015, Elon Musk announced that his company, SpaceX, would be deploying satellites to orbit that would provide high-speed broadband internet access to the entire world. Known as Starlink, SpaceX began deploying this constellation in May of 2019 with the launch of the first 60 satellites. As of April 22, a total of 422 satellites have been added to the Starlink constellation, and the response hasn’t been entirely positive.
In addition to fears that we’re adding to the problem of “space junk,” there are also those who’ve expressed concern that Starlink and other constellations could have a negative impact on astronomy. In response, SpaceX recently announced that it will be instituting changes in how the satellites are launched, how they orbit the Earth, and even how reflective they are in order to minimize the impact they have on astronomy.
These changes were the subject of a presentation made during the Decadal Survey on Astronomy and Astrophysics 2020 (Astro2020) hosted by the National Academy of Sciences, Engineering, and Medicine. As part of the Optical Interference from Satellite Constellations Meeting held on Monday, April 27th, the Starlink Panel (which included Musk) presented how the company hopes to minimize light pollution caused by their constellation.
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.
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.
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.
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 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.
