Neptune has been directly explored by one space probe, Voyager 2, in 1989. As of September 2023, there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch in 2024

How do we explore Neptune

With no new space missions to Neptune since Voyager 2, scientists have relied on the Hubble Space Telescope and large ground-based telescopes to regularly observe the planet. The observations have discovered more moons, monitored seasonal storms, and even detected gases in Triton’s thin atmosphere.

Why should we explore Neptune

But we need to understand our giant ice worlds before we can understand the vast population of similar planets in the galaxy. We’ve only visited once. Now is the time for a mission to Uranus or Neptune to explore one of the planets, its extended magnetic field, atmosphere, satellites and ring systems.

Of Neptune’s 14 moons, the researchers chose the largest, Triton, as their target for an aerobraking assist. According to a recent paper they released on arXiv (which, like all papers on arXiv, has not yet been peer-reviewed), they were inspired by work that used the atmosphere on Titan to aerobrake a spacecraft into the Saturnian system that was done back in the 90s.

What do you mean by aero braking

Aerobraking is a spaceflight technique wherein an orbiting spacecraft brushes against the top of a planetary atmosphere. The friction of the atmosphere against the surface of the spacecraft slows down and lowers the craft’s orbital altitude

Does nasa use aero braking

NASA’s Mars Global Surveyor spent nine years in orbit above the Red Planet, setting a longevity record later broken by NASA’s Mars Odyssey. The spacecraft pioneered the use of aerobraking at Mars, using a series of dips into the planet’s atmosphere to slow the spacecraft and refine its orbit

Can we use aero braking on mars

Magellan used aerobraking maneuver to reduce its orbital period from 3.23 h to 1.57 h. Following the Magellan’s success, three Mars missions have used aerobraking as an enabling technology to reduce the propellant requirement to enter the target science orbits.
