IRON AND ICE
A Map of Rosetta's Comet

Munich, Germany (SPX) Sep 11, 2014


In this view of the "belly" and part of the "head" of comet 67P/Churyumov-Gerasimenko, several morphologically different regions are indicated. ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA.

High-resolution images of comet 67P/Churyumov-Gerasimenko reveal a unique, multifaceted world. ESA's Rosetta spacecraft arrived at its destination about a month ago and is currently accompanying the comet as it progresses on its route toward the inner solar system.

Scientists have now analyzed images of the comet's surface taken by OSIRIS, Rosetta's scientific imaging system, and allocated several distinct regions, each of which is defined by special morphological characteristics. This analysis provides the basis for a detailed scientific description of 67P's surface. It was presented at the European Planetary Science Congress 2014.

"Never before have we seen a cometary surface in such detail", says OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS) in Germany. In some of the images, one pixel corresponds to 75 centimeters scale on the nucleus. "It is a historic moment, we have an unprecedented resolution to map a comet", he adds.

With areas dominated by cliffs, depressions, craters, boulders or even parallel grooves, 67P displays a multitude of different terrains. While some of these areas appear to be quiet, others seem to be shaped by the comet's activity. As OSIRIS images of the comet's coma indicate, the dust that 67P casts into space is emitted there.

"This first map is, of course, only the beginning of our work", says Sierks. "At this point, nobody truely understands, how the morphological variations we are currently witnessing came to be."

As both 67P and Rosetta travel closer to the Sun in the next months, the OSIRIS team will monitor the surface looking for changes. While the scientists do not expect the borderlines of the comet's regions to vary dramatically, even subtle transformations of the surface may help to explain, how cometary activity created such a breathtaking world.

Next weekend, on 13 and 14 September 2014, the maps will offer valuable insights as Rosetta's Lander Team and the Rosetta orbiter scientists gather in Toulouse to determine a primary and backup landing site from the earlier preselection of five candidates.

Rosetta Comet is Darker than Charcoal
Pasadena CA (JPL) Sep 08, 2014
Rosetta scientists also discovered the comet's surface so far shows no large water-ice patches. The team expected to see ice patches on the comet's surface because it is too far away for the sun's warmth to turn its water into vapor. "We're a bit surprised at just how unreflective the comet's surface is and how little evidence of exposed water-ice it shows," said Alan Stern, Alice principa ... read more
