Waves Hit Different On Other Planets

by Keith CowingApril 20, 2026April 20, 2026

On a calm day, a light breeze might barely ripple the surface of a lake on Earth. But on Saturn’s largest moon Titan, a similar mild wind would kick up […]

Example of altimeter echo received from plains. This waveform was recorded during flyby T30 from an altitude of 1964.9 km at an incidence angle 0.0137°. Panel (a) shows a context map. Section of the T30 altimeter track observing the plains from point A to C. The waveform resulting from the integration of three echoes (Burst ID 131027162/4) located at point B is shown in panel (b) the altimetric model is used to fit the echo, resulting in an estimated RMS height of 4 m over the 115 square km footprints. The fitting error is indicated as a percentage by the mean integral relative error (MIRE). Panel (c) shows the large-scale topography of the plains using three elevation trackers, Maximum Likelihood, Threshold, and First Moment. All three trackers agree that the overall surface height changes less than 50 m over 50 km. -- JGR Planets

Titan’s Plains Revealed: Evidence For A Layered Surface

by Keith CowingApril 10, 2026April 10, 2026

Undifferentiated plains are the most common terrain type on Titan, yet their composition and geologic history remain poorly understood.

Artist’s impression of the simulations conducted in this research. Jupiter (lower left) has a strong magnetic field which creates a cavity in its circumplanetary disk. Saturn (upper right) lacks a strong magnetic field so its circumplanetary disk evolves without a cavity. Credit: Yuri I. Fujii/L-INSIGHT [Kyoto University], Illustrator: Shinichiro Kinoshita

Experimental Insights Into The Azotosome Hypothesis In Titan’s Lake Fluid

by Keith CowingApril 5, 2026April 5, 2026

Since the discovery of hydrocarbon lakes and seas on Saturn’s moon Titan, there has been much speculation on whether these could serve as suitable environments to host exotic life.

Fully corrected and calibrated albedos of Titan (yellow), Saturn (green), Uranus (blue), and Neptune (red) covering 0.3 µm to 2.1 µm, offset for clarity. Regions of strong telluric absorption are masked in lighter shades, and it should be noted that they are less reliably corrected. The flat regions in the UV were flagged as bad pixels in all images by X-shooter. We also highlight a vertical discontinuity between the VIS and NIR arms of Titan, which is likely due to weather inconsistency. The colors used for these objects are the same in the following figures. -- Astronomy & Astrophysics

Dragonfly Mission’s Guest Investigator Program

by Keith CowingMarch 20, 2026March 20, 2026

Applications are currently being accepted for Cohort 7 of the Dragonfly Mission’s Guest Investigator Program, with applications due May 29th.

From left, Carlisa Drew, Seth Harvey, Anthony Fanelli, Emory Toomey and TJ Lee conduct power and functional testing on Dragonfly’s Integrated Electronics Module (IEM) and Power Switching Unit (PSU) in the cleanroom at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. The IEM is Dragonfly’s “brain,” containing the spacecraft’s core avionics; the PSUs control the flow of power to Dragonfly’s instruments and systems. NASA/Johns Hopkins APL/Ed Whitman
