In a groundbreaking proposal, researchers have put forth a radical new idea for a potential future mission to explore Neptune, the solar system’s outermost planet. With the only visit to Neptune conducted by the Voyager 2 probe in the 1980s, scientists have long been interested in returning to this mysterious world. However, the extreme distance and challenges posed by the planet’s vicinity have made it an insurmountable task, until now.
The proposal, detailed in a paper appearing in the preprint database arXiv, suggests leveraging the extremely thin atmosphere of Triton, Neptune’s largest moon, as a means to capture a spacecraft. Triton’s atmosphere, despite being over 70,000 times less dense than Earth’s, has been found to have the potential to sufficiently slow down a spacecraft and allow it to enter into a captured orbit around Neptune.
The researchers drew inspiration from NASA’s successful Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) in 2022. This program aimed to develop an inflatable shield, known as an aeroshell, to protect a spacecraft during atmospheric descent and enable a controlled landing. The idea now proposes using a similar aeroshell to slow down and ultimately capture a future Neptune orbiter.
To achieve this, the proposed mission would navigate the orbiter to approach Triton and adjust the angle of the aeroshell to fine-tune the orbiter’s course towards Neptune. The researchers estimate that the orbiter would need to descend as low as 6 miles (10 kilometers) above Triton’s surface, a relatively low altitude posing minimal risk of collision.
While similar approaches have been suggested for Saturn’s moon Titan, Triton’s thinner atmosphere and proximity to Neptune make it a more feasible option. As a result, the mission to Neptune could potentially be completed in as little as 15 years, significantly shorter than other current mission ideas. This is because the orbiter would not require a substantial amount of fuel to slow itself down upon arrival at Neptune.
Apart from the unprecedented opportunity to study Neptune up close, this mission would also offer a unique chance to observe Triton, one of the solar system’s most peculiar objects. Triton, believed to be a captured Kuiper Belt object, would be seen from a vantage point just a few kilometers above its surface, providing valuable scientific insights.
While the proposal is still in the theoretical stages, it presents an exciting potential avenue for future exploration of Neptune. The prospect of a return mission to this enigmatic planet could significantly deepen our understanding of the outer solar system and unveil new mysteries waiting to be unraveled.
As scientists continue to innovate and push the boundaries of space exploration, humanity edges closer to achieving the remarkable feat of orbiting Neptune, a world that has captivated our curiosity for decades.
