SpaceX's new direct-to-cell Starlink satellites are brighter than the originals

SpaceX's new direct-to-cell Starlink satellites are significantly brighter than their predecessors, shining nearly five times brighter in the night sky. These satellites, designed to connect directly to smartphones, orbit at a lower altitude of 217 miles (350 kilometers) compared to the traditional Starlink satellites at 340 miles (550 kilometers). Since the launch of the first batch in January 2024, SpaceX has successfully demonstrated text messaging and video calls using these satellites, with plans to collaborate with T-Mobile for broader service rollout. Currently, over 100 direct-to-cell satellites are in low Earth orbit, with a request to the FCC to operate up to 7,500. Despite their brightness, which raises concerns among astronomers, the satellites move faster and spend more time in Earth's shadow, potentially mitigating some negative impacts on astronomical observations. SpaceX has previously implemented brightness mitigation techniques for regular Starlink satellites, which could also be applied to the new DTC satellites, although they would still be 2.6 times brighter. The rapid deployment of satellites raises concerns about space debris and its implications for both satellite operations and astronomy, with experts warning of potential collisions and environmental impacts.

- SpaceX's direct-to-cell Starlink satellites are nearly five times brighter than traditional models.

- The satellites operate at a lower altitude, enhancing their visibility.

- Over 100 DTC satellites are currently in orbit, with plans for more.

- Brightness mitigation techniques may reduce luminosity but not eliminate it entirely.

- Concerns about space debris and its impact on satellite operations and astronomy are growing.
