Looks like David Bowie’s Ziggy Stardust
and the Spiders from Mars may have not been too far off – at least planet-wise.
Here’s a newly issued image taken by
NASA’s Mars Global Surveyor using its Mars Orbiter Camera operated by Malin
Space Science Systems (MSSS).
Taken
during the southern summer season, the photo shows an area adjacent to the red
planet’s south polar residual cap. Several intricate fracture networks are
seen, each network involving multiple factures are radiating from a central
spot.
Looking
like a squad of marching Mars spiders, the origin of these features is not
understood, note experts at MSSS.
Some investigators have speculated that these are sites of release of carbon
dioxide from beneath the ground. But this explanation seems inadequate to
explain all attributes of the features, according to MSSS researchers.
Also,
Mars Global Surveyor flyovers of the area have shown that these features have
not been changing from year to year during the course of the spacecraft’s mission.
Mars
Global Surveyor was launched in November 1996 and has been in Mars orbit since
September 1997.
