Scientists plan to sail the lakes of Titan

After the successful landing of `Curiosity` rover on Mars, scientists now plan to navigate the seas of Saturn`s largest moon, Titan.

London: After the successful landing of `Curiosity` rover on Mars, scientists now plan to navigate the seas of Saturn`s largest moon, Titan.

According to scientists presenting their proposals at the European Planetary Science Congress, this outlandish scenario could soon become a reality.

The new project, called the Titan Lake In-situ Sampling Propelled Explorer, proposes a boat-probe, propelled by wheels, paddles or screws.

The probe would land in the middle of Ligeia Mare (the biggest lake, near Titan`s north pole), then set sail for the coast, taking scientific measurements along the way. The mission would last around six months to a year.

"The main innovation in TALISE is the propulsion system," Igone Urdampilleta, a member of the TALISE team said.

"This allows the probe to move, under control, from the landing site in the lake, to the closest shore. The displacement capability would achieve the obtaining of liquid and solid samples from several scientific interesting locations on Titan`s surface such as the landing place, along the route towards the shore and finally at the shoreline," Urdampilleta said in a statement.

The TALISE concept is being developed as a partnership between SENER, a private engineering and technology group and the Centro de Astrobiologia in Madrid, Spain.

This mission concept is the result of a `phase 0` study. In the following phases the feasibility study and a preliminary mission architecture would be realised to consolidate a possible technical proposal for future space science mission call.

Titan is one of the most Earth-like bodies in the Solar System. With a thick atmosphere, a diameter between that of Earth and the planet Mercury, and a network of seas, lakes and rivers, it is in many respects more like a planet than a moon like Earth`s.

The satellite`s atmosphere is made up largely of nitrogen (like Earth`s), is rich in organic compounds and hydrogen cyanide, which may have played a role in the emergence of life on Earth.

The Cassini-Huygens mission, which studied Titan extensively in the 2000s, confirmed that lakes, seas and rivers of liquid hydrocarbons (similar to household gas) exist, covering much of the satellite`s northern hemisphere.

Although it eventually landed on solid ground, the Hugyens lander was designed to be able to float for a short period.
