GPS constellations have become foundational in modern society supporting everything from navigation to financial services, making the impacts of GPS disruptions all the more concerning.
As reliance on these systems have grown, so too have efforts by threat actors to disrupt them through techniques such as jamming and spoofing. As these attacks have become more effective, they are becoming increasingly common, especially in conflict zones where disruption and confusion can prove exceedingly valuable.

Since its original creation in the 1970s, GPS has evolved from a technology primarily used by the military to a foundation for modern society.
After the removal of selective availability for civilians in 2000, GPS’s value has significantly expanded. In the past two decades, nearly every critical infrastructure sector–telecommunications, transportation, energy, agriculture, emergency services, and financial services–relies on GPS constellations to ensure that timing and location accuracy are precise. Though many do not see its utility in day-to-day efforts, GPS has become entrenched in modern networks and services.

Despite being an indispensable technology, traditional GPS remains vulnerable to exploitation and is needed for an update.
In this week's episode, host Maria Varmazis sits down with Dr. Sean Gorman, CEO of Zephr.xyz, to discuss the current state of GPS. For decades, GPS has been a cornerstone technology for private, public, and military entities; however, through new technological advancements, companies and governments are looking to modernize this technology.

This week on our Deep Space episode, Maria speaks with TransAstra's CEO Joe Sercel about their recently demonstrated capture-bag technology aboard the ISS, drawing attention for its potential role in orbital debris cleanup. Debris removal is only the beginning. The real goal is far bigger: asteroid mining as future space infrastructure.
Sercel walks us through how the same capture system designed to safely enclose debris could eventually be used to secure near-Earth asteroids—unlocking access to water, propellant, and raw materials that enable sustained operations beyond Earth orbit.. Learn more about TransAstra's work.

Please enjoy this encore while the team is out on vacation.
When satellites burn up upon re-entering Earth’s atmosphere, they release particles and gases, including metals like aluminium, which may affect atmospheric chemistry. This process, known as atmospheric ablation, is still poorly understood, but early evidence suggests metal content in the atmosphere is rising. To address these uncertainties, the UK Space Agency commissioned three targeted studies to investigate the potential impacts of satellite re-entry. We spoke to Professor Minkawn Kim from the University of Southampton about his findings.
You can hear the Professor’s chat with Maria from 2024 here.
