However, this digital connectivity comes at a cost: vulnerability to cyber threats that can penetrate these intricate technological webs. Just like any other advanced system, satellites are not immune to cyber-attacks and must grapple with the same risks and challenges.
One notable development in the satellite industry is the emergence of large constellations comprising numerous satellites launched into Low Earth Orbit (LEO). While this advancement promises enhanced global connectivity and expanded capabilities, it also raises enduring concerns among diverse groups of stakeholders.
Traditional satellite operators, who have long been the custodians of the space domain, find themselves faced with novel challenges. These challenges involve managing the complexities of operating and maintaining large constellations and protecting them from malicious cyber intrusions.
The scientific community, particularly astronomers, also voice their apprehensions. The proliferation of satellites in LEO can have adverse effects on astronomical observations, disrupting the delicate balance of our exploration of the cosmos. The increased presence of satellites in the night sky can obstruct celestial observations and hinder our understanding of the universe.
Beyond these traditional concerns, a growing number of activists have joined the cause of safeguarding the space environment. They recognise the importance of preserving the pristine nature of space and preventing the proliferation of space debris. As satellites become more ubiquitous and constellations grow in number, these activists advocate for responsible satellite deployment and the adoption of measures to mitigate the potential environmental impact.
