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.

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

Icy Worlds: Moons And Dwarf Planets

by Keith CowingDecember 1, 2025December 1, 2025

In the outer solar system beyond Jupiter, water ice is a dominant component of planetary bodies, and most solid objects in this region are classified as icy bodies.

Dragonfly Astrobiology Mission Progresses Through Key Development And Test Activities

by Keith CowingSeptember 9, 2025September 9, 2025

NASA’s Dragonfly mission has cleared several key design, development and testing milestones and remains on track toward launch in July 2028.

On 15 October 1997, NASA's Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA's Huygens probe, destined for Saturn's largest moon, Titan. The final chapter of the interplanetary trek for Huygens began on 25 December 2004 when it deployed from the orbiter for a 21-day solo cruise toward the haze-shrouded moon. Plunging into Titan’s atmosphere, on 14 January 2005, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface. Larger image -- ESA

Thermal Inertia Controls on Titan’s Surface Temperature and Planetary Boundary Layer Structure

by Keith CowingJuly 2, 2025July 2, 2025

Understanding Titan’s planetary boundary layer (PBL) — the lowest region of the atmosphere influenced by surface conditions — remains challenging due to Titan’s thick atmosphere and limited observations.

Observation sequences used in this study. Spectra are binned in 2° latitude bins. Points are plotted at the central latitude of the bin and at the average longitude of the bin. Color indicates the acquisition date of the observation. -- University of Bristol

Titan’s Mysterious Wobbling Atmosphere Is Like A Gyroscope

by Keith CowingMay 23, 2025

The puzzling behaviour of Titan’s atmosphere has been revealed by researchers at the University of Bristol for the first time.

The ESA Huygens Probe entered the upper layers of the atmosphere of Titan at 6 km/s. The speed was reduced to about 400 m/s in less than 2 minutes, thanks to the friction of the heat shield with the atmospheric gas. The temperature of the gas in the shock wave in front of the heat shield can reach 12000degC, while the heat shield can reach 1880degC. IMAGE
