Water ice, but what kind? Evidence for clathrates in 67P

For decades, scientists have agreed that comets are mostly water ice, but what kind of ice — amorphous or crystalline — is still up for debate.

Rosetta observation of the surprising distribution of water vapor and carbon dioxide surrounding comet 67P

One of the goals of the Rosetta mission was to get a better understanding of the release of the gases and the dust as the surface of the comet slowly warms up.

Looking beneath the surface of comet 67/P

As Rosetta flies alongside Comet 67/P, we seek to understand in detail how the comet nucleus behaves as it approaches and recedes from the Sun.

A Look at MIRO Operations Planning

The Rosetta spacecraft has 11 instruments on-board, all dedicated to studying comet 67P. While these instruments can all operate simultaneously, the science teams for each instrument have differing science goals, resulting in varying requirements for where Rosetta points. To give each instrument a chance to make its measurements, we set up blocks of time approximately four hours long, and the teams take turns commanding Rosetta for each of those blocks.

Software Updates in Space

Yesterday, 2 March 2016, the MIRO team confirmed that a software update was successfully received and installed.

Contributions of Amateur Observers in Support of ESA/Rosetta Mission from 2014 - 2016

Following two years of observing comet 67P/Churyumov-Gerasimenko (CG) or Chury (as it is fondly referred to now), a dedicated group of amateur observers has proven to be a great resource, creating a synergy between using social media, amateur and professional observers.

Comet 67P/Churyumov-Gerasimenko: Where does all its dust go?

Fred Whipple was the first scientist to describe comets as “dirty ice balls”. In their journeys into the inner Solar System, comets are heated up by sunlight and form the spectacular coma, tail, and jets that are their calling cards.

This week with MIRO

The Rosetta spacecraft was hovering between 40 and 50 km above the comet this week. A simulated view from the vantage point of the MIRO instrument for February 14th (Valentine's Day) is shown. The red and green circles show the footprints of the MIRO observation region...

Approaching the Sun: Comet 67P/Churyumov–Gerasimenko and Rosetta

Unexpected jets, increase of dust emissions in both quantity and speed -- can you tell? We are almost at perihelion (closest approach to the Sun) with comet 67P/Churyumov–Gerasimenko and the Rosetta spacecraft.
