Saturn’s Moon Titan Could Have Formed in a Merger of Two Old Moons

by Keith CowingFebruary 11, 2026

Recent research suggests that Saturn’s bright rings and its largest moon, Titan, may have both originated in collisions among its moons.

Astrobiology Droid Update: Dragonfly Aerodynamic Testing

by Keith CowingFebruary 9, 2026

In sending a car-sized rotorcraft to explore Saturn’s moon Titan, NASA’s Dragonfly mission will undertake an unprecedented voyage of scientific discovery. And the work to ensure that this first-of-its-kind project […]

Dragonfly Mission: Optomechanical Design Of The DragonCam Microscopic Camera

by Keith CowingJanuary 22, 2026January 22, 2026

The DragonCam Microscopic Camera is an instrument being developed for NASA’s Dragonfly mission [1] to Saturn’s moon Titan.

Cumulative crater count as a function of crater diameter. Each symbol and line depicts a fit to a different methane-clathrate thickness (see legend). The darkblue dotted line shows Titan’s observed crater count (Hedgepeth et al., 2020). The shaded region indicates craters less than 22 km, which is the lower limit of our results. Note that those craters are affected by Titan’s atmosphere, hence the drop off from the trend line. Panel b shows the inset of Panel a (a black box), so the details near the change in slope can be seen more clearly. -- astro-ph.EP

A Youthful Titan Implied By Improved Impact Simulations

by Keith CowingJanuary 15, 2026January 15, 2026

The small number of impact craters found on Titan suggests that its surface is relatively young. Previous work estimated its surface age to be between 200 and 1000 Myr. This […]

One set of images taken by Huygens is pictured here showing the view from 2 km altitude. It is in Mercator projection, so the N–S/E–W directions cross at right angles but surface areas appear distorted. Sky above horizon is modfied for formatting.- ESA/Astrobiology.com Original image

Absence Of A Subsurface Ocean On Titan Indicated By Cassini Data

by Keith CowingJanuary 7, 2026January 7, 2026

The Cassini spacecraft orbited Saturn from 2004 to 2017, performing over a hundred flybys of Titan, Saturn’s largest moon.

Histograms and uncertainty ellipse (red) for computed Re(k2) and Im(k2) compared with the observed uncertainty ellipse (black) for the interior models of Titan without (a) and with (b) an ocean. The centre and axes of the ellipses are computed from the covariance matrix of the posterior distributions obtained from the interior inversion (1σ level of uncertainty). -- Nature via PubMed

Titan’s Strong Tidal Dissipation Precludes A Subsurface Ocean

by Keith CowingDecember 24, 2025December 24, 2025

The Cassini mission provided unprecedented insights into Saturn’s largest moon, Titan, from its atmosphere to the deep interior.

This artist’s concept depicts NASA’s Cassini spacecraft performing one of its many close flybys of Titan, Saturn’s largest moon. By analyzing the Doppler shift of radio signals traveling to and from Earth, the mission precisely measured Titan’s gravity field. Credit: NASA/JPL-Caltech

Titan May Not Have A Global Ocean

by Keith CowingDecember 17, 2025December 17, 2025

A key discovery from NASA’s Cassini mission in 2008 was that Saturn’s largest moon Titan may have a vast water ocean below its hydrocarbon-rich surface. But reanalysis of mission data […]

A New Look At TRAPPIST-1e, An Earth-sized, Habitable-zone Exoplanet

by Keith CowingDecember 5, 2025December 5, 2025

Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention of scientists, because it orbits the star within the “Goldilocks zone” […]
