Mars mystery: Space experts detect weird ’wobble’ moving Martian poles around

The wobble should, in theory, naturally diminish within a century of its start.

However, Earth’s oddly enduring wobble has actually been in effect for much longer than this.

One 2001 study theorised a combination of atmospheric pressure changes and its oceans is behind this jiggle – although this remains a source of controversy.

Authors of research detected the wobble after examining 18 years of data collected by Mars Odyssey, NASA’s Mars Reconnaissance Orbiter and the Mars Global Surveyor.
