3D-printed ‘Space-age’ antenna could be face of satellite communication

Interesting Engineering | Christopher McFadden | 03-01-2024

Researchers at UBC and Drexel University have developed a new MXene-based material that has the potential to revolutionize telecommunications. This lightweight, 3D-printable material can be used to create antennas, waveguides, and filters that are similar in performance to traditional metal components, but are 10 to 20 times lighter, less expensive, and easier to manufacture. MXenes are a new class of two-dimensional materials that can be combined with polymers to create conductive components. This new material can be applied to surfaces from a water-based dispersion, making it easy and efficient to use. The researchers believe that this new material has the potential to impact the design and manufacturing of electronic communication devices in a variety of industries, including aerospace, satellite, and medical imaging.

Iridium has partnered with the South Korean military to provide secure communication and data tracking capabilities for its soldiers. This collaboration involves supplying over 1,000 special devices that leverage Iridium's reliable satellite network for functionalities like real-time positioning and messaging. This project is expected to enhance the South Korean military's operational efficiency and tactical awareness. Additionally, Iridium recently announced an extension to its existing satellite fleet's lifespan, further strengthening its service offerings.

Cybersecurity for satellites is a growing challenge as threats to space-based infrastructure grow

Tech Xplore | Slyvester Kaczmarek | 02-21-2024

Our dependence on satellites for vital services like GPS and banking makes them prime targets for cyberattacks. These attacks could disrupt or disable crucial systems, highlighting the need for robust cybersecurity measures. Recent events, like the attack on the KA-SAT network, showcase the vulnerability of satellites. The evolving nature of threats, with attackers using AI and exploiting software vulnerabilities, demands a proactive approach. Measures like encryption and AI-powered detection systems are being developed to combat these threats. The unique challenges of space, like signal jamming and limited processing power, necessitate innovative solutions. International collaboration among space agencies, technology companies, and governments is crucial to develop comprehensive cyber defenses for space assets. Securing space infrastructure goes beyond technical challenges, impacting international relations, economic stability, and the future of space exploration.

SpaceX launches Leap Day Starlink satellites into orbit, lands rocket at sea

Space.com | Tariq Malik | 02-29-2024

SpaceX launched 23 Starlink internet satellites into orbit on February 29th, following a delay in their astronaut launch due to weather concerns. This launch, named Starlink 6-40, used a previously flown Falcon 9 rocket and deployed the Version 2 Mini satellites into low Earth orbit. This is part of SpaceX's ongoing effort to build a massive network of satellites to provide internet access from space, with an ultimate goal of having up to 42,000 in orbit.

Space Force general warns of ‘window of vulnerability’ in satellite defense

Space News | Sandra Erwin | 02-29-2024

General Stephen Whiting, head of the U.S. Space Command, warned during a Senate hearing that the US faces a critical period in the next few years where its space assets are vulnerable to attacks. He identified China and Russia as the primary threats due to their development of anti-satellite weapons. Whiting expressed particular concern about China's rapidly growing fleet of surveillance satellites, highlighting their potential to track and target US forces. He emphasized the importance of surpassing China's advancements and stressed the need for long-term investments in robust space defense systems. While the Space Command has achieved operational capability, Whiting cautioned that it lacks sufficient capabilities to fully counter the growing threats. He outlined a list of crucial requirements, including advanced sensors and robust cyber defenses, which need funding and implementation by 2027 to safeguard the US advantage in space. He emphasized that without these investments, the US risks falling behind its competitors in the crucial space domain.

Space Force to lean on private sector for space tracking data

Space News | Sandra Erwin | 02-27-2024

"The U.S. Space Force is looking to collaborate with private companies to improve its ability to track and monitor objects in space. This "space domain awareness" is crucial for avoiding collisions and keeping an eye on potential threats. General David Miller, head of Space Operations Command, believes commercial firms can provide valuable data and analytics, but emphasizes that affordability, reliability, and timeliness are key factors. Space Force officials acknowledge the limitations of current systems and the growing challenges posed by increasing space traffic. They are working on a strategy to leverage commercial expertise while maintaining core military capabilities.
