The first five payloads from the Space Development Agency, an organization charged with rapidly infusing emerging technologies into the U.S. military’s space programs, are among more than 80 satellites awaiting launch from Cape Canaveral Tuesday on a SpaceX Falcon 9 rocket.

Established in 2019, the Space Development Agency plans to deploy hundreds of small satellites to enable improved communications for the U.S. military. SDA’s strategy leans on the rapid development of new commercial space technology, including new types of sensors and cheaper, easier-to-produce small satellites that can be deployed in large constellations in low Earth orbit.

SDA plans to launch the first tranche of 28 satellites to provide initial infrared missile detection and low-latency data relay services in late 2022 and early 2023. Twenty of those satellites, part of the “transport layer,” will be developed by Lockheed Martin and York Space Systems for communications support. The other eight “tracking” satellites will be supplied by SpaceX and L3Harris for missile detection and tracking.

An international group of astronomers has created images with never-before-seen detail of a galaxy cluster with a black hole at its center, traveling at high speed along an intergalactic “road of matter.” The findings also support existing theories of the origins and evolution of the universe.

The concept that roads of thin gas connect clusters of galaxies across the universe has been difficult to prove until recently, because the matter in these ‘roads’ is so sparse it eluded the gaze of even the most sensitive instruments. Following the 2020 discovery of an intergalactic thread of gas at least 50 million light-years long, scientists have now developed images with an unprecedented level of detail of the Northern Clump—a cluster of galaxies found on this thread.

By combining imagery from various sources including CSIRO’s ASKAP radio telescope, SRG/eROSITA, XMM-Newton and Chandra satellites, and DECam optical data, the scientists could make out a large galaxy at the center of the clump, with a black hole at its center.

Satellite imagery is becoming ubiquitous. Research has demonstrated that artificial intelligence applied to satellite imagery holds promise for automated detection of war-related building destruction. While these results are promising, monitoring in real-world applications requires high precision, especially when destruction is sparse and detecting destroyed buildings is equivalent to looking for a needle in a haystack. We demonstrate that exploiting the persistent nature of building destruction can substantially improve the training of automated destruction monitoring. We also propose an additional machine-learning stage that leverages images of surrounding areas and multiple successive images of the same area, which further improves detection significantly. This will allow real-world applications, and we illustrate this in the context of the Syrian civil war.

Existing data on building destruction in conflict zones rely on eyewitness reports or manual detection, which makes it generally scarce, incomplete, and potentially biased. This lack of reliable data imposes severe limitations for media reporting, humanitarian relief efforts, human-rights monitoring, reconstruction initiatives, and academic studies of violent conflict. This article introduces an automated method of measuring destruction in high-resolution satellite images using deep-learning techniques combined with label augmentation and spatial and temporal smoothing, which exploit the underlying spatial and temporal structure of destruction. As a proof of concept, we apply this method to the Syrian civil war and reconstruct the evolution of damage in major cities across the country. Our approach allows generating destruction data with unprecedented scope, resolution, and frequency—and makes use of the ever-higher frequency at which satellite imagery becomes available.

U.K. start-up Arqit expects to launch a worldwide service for sharing unbreakable quantum-encrypted messages using satellites in 2023.

The U.S. Space Development Agency has five satellites riding on SpaceX’s Transporter-2 mission scheduled to launch June 25.

WASHINGTON — The U.S. Space Development Agency has five satellites riding on SpaceX’s Transporter-2 rideshare mission scheduled to launch June 25.

“There’s nothing in the space business that gets your blood pumping like the idea of a launch, especially if you’ve got multiple satellites,” a senior Space Development Agency (SDA) official told reporters June 22. “We’re really excited about what’s going to happen.”

Russia is planning to send a nuclear-powered spacecraft to the grand gas giant of the Solar System, Jupiter, in 2030.

Roscosmos, Russia’s federal space agency, announced the plan for the mammoth 50-month journey last week. The journey will take it on a mini tour of the Solar System, taking pit stops around the Moon and Venus, dropping off spacecraft along its way, before heading on to Jupiter.

More specifically, a “space tug” with a nuclear-based transport and energy module dubbed Zeus will head towards the Moon where a spacecraft will separate from it. It will then pass by Venus to perform a gravity assist maneuver and drop off another spacecraft, before venturing towards Jupiter and one of its satellites.

SYDNEY, June 22 (Reuters) — Starlink, the satellite internet unit of Elon Musk’s SpaceX, expects to be able to provide continuous global coverage by around September but will then need to seek regulatory approvals, its president Gwynne Shotwel said on Tuesday.

“We’ve successfully deployed 1800 or so satellites and once all those satellites reach their operational orbit, we will have continuous global coverage, so that should be like September timeframe,” she told a Macquarie Group (MQG.AX) technology conference via webcast.

“But then we have regulatory work to go into every country and get approved to provide telecoms services.”

The Export-Import Bank of the U.S. has arranged financing for the SpaceX launch of a Hispasat satellite, the first space deal it has done in six years.

WASHINGTON — The Export-Import Bank of the United States has arranged financing for the SpaceX launch of a Hispasat satellite, the first space deal the bank has done in six years.

Ex-Im announced June 21 that it approved $80.7 million in financing for a Falcon 9 launch of a Hispasat satellite, Amazonas Nexus, as well as launch and initial in-orbit insurance. The bank said the financing will be in the form of either a direct loan or a loan guarantee.
