TL;DR: In this paper, the authors reported high-resolution radio observations of a second Galactic superluminal radio source GRO J1655-40, which was detected as an X-ray transient on 27 July 1994.
Journal ArticleDOI
Interior Structure and Seasonal Mass Redistribution of Mars from Radio Tracking of Mars Pathfinder
TL;DR: Doppler and range measurements to the Mars Pathfinder lander made using its radio communications system have been combined with similar measurements from the Viking landers to estimate improved values of the precession of Mars' pole of rotation and the variation in Mars' rotation rate as discussed by the authors.
