Editing Astronomical transit (section)

=== Notable observations ===
No missions were planned to coincide with the transit of [[Earth]] visible from [[Mars]] on 11 May 1984 and the Viking missions had been terminated a year previously. Consequently, the next opportunity to observe such an alignment will be in 2084.

On 21 December 2012, the ''[[Cassini–Huygens]]'' probe, in orbit around [[Saturn]], observed the planet [[Venus]] transiting the Sun.<ref>''[http://spacecoastdaily.com/2012/12/cassini-spacecraft-tracks-venus-transit-from-saturn/ Cassini Spacecraft Tracks Venus Transit From Saturn]'', Space Coast Daily.

On 3 June 2014, the Mars rover [[Curiosity (rover)|''Curiosity'']] observed the planet [[Mercury (planet)|Mercury]] transiting the Sun, marking the first time a [[planetary transit]] has been observed from a celestial body besides Earth.<ref name="NASA-20140610">{{cite web|url=http://www.jpl.nasa.gov/news/news.php?release=2014-183|title=Mercury Passes in Front of the Sun, as Seen From Mars|last=Webster|first=Guy|date=10 June 2014|work=[[NASA]]}}</ref>
