Philae science results: Comet 67P is crunchy on the outside, soft on the inside

Emily Lakdawalla • May 09, 2018 • 1

What is the surface of a comet like? That's one of the main questions that motivated Philae's mission to the surface of comet 67P/Churyumov-Gerasimenko. We now know the comet has a rigid crust about 10 to 50 centimeters thick, below which the comet is much more fluffy.

A Comet or Titan: The Next New Frontiers Mission

Both would do compelling science in the mid-2030s. Otherwise the two missions could not be more different.

Citizen scientist spots changes on Rosetta's comet

Marco Parigi • February 27, 2017 • 3

Citizen scientist and self-described "comet whisperer" Marco Parisi explains how he made a striking discovery on Comet 67P using Rosetta mission data.

Rosetta in the Rearview: What Have We Learned?

John Noonan • November 07, 2016 • 1

Just over a month ago the European Space Agency’s Rosetta spacecraft finished its mission by spectacularly diving into the comet 67P/Churyumov-Gerasimenko. How did it observations influence and alter our ideas about the typical formation and lifetime of a comet?

Rosetta is gone

Emily Lakdawalla • September 30, 2016 • 6

Today there is one less spacecraft returning science data from beyond Earth. The European Space Operations Centre received the final transmission from Rosetta at 11:19 September 30, UT.

Rosetta spacecraft may be dying, but Rosetta science will go on

Emily Lakdawalla • September 29, 2016 • 3

The Rosetta mission will end tomorrow when the spacecraft impacts the comet. ESA took advantage of the presence of hundreds of members of the media to put on a showcase of Rosetta science. If there’s one thing I learned today from all the science presentations, it’s this: Rosetta data will be informing scientific work for decades to come.

Rosetta end-of-mission update

Emily Lakdawalla • September 09, 2016 • 5

The European Space Agency has shared plans for the end of the Rosetta mission scheduled for September 30, just three weeks from now. The landing site will be located on the "head" of the comet, next to a prominent pit now named Deir el-Medina.

Philae spotted on the surface of comet Churyumov-Gerasimenko

Emily Lakdawalla • September 06, 2016 • 1

Ever since its landing, Philae has been elusive. It went silent just three days later and never returned any more science data, though it made brief contact with the orbiter last summer. Now, just a month until the planned end of the Rosetta mission, the orbiter has finally located the lander in a stunning high-resolution view of the surface.

Rosetta end-of-mission plans: Landing site, time selected

Emily Lakdawalla • July 26, 2016 • 2

ESA's comet-chasing Rosetta spacecraft is nearing the end of its mission. Last week, ESA announced when and where Rosetta is going to touch down. And tomorrow, it will forever shut down the radio system intended for communicating with the silent Philae lander.

A feast of new OSIRIS photos from comet 67P

Emily Lakdawalla • May 11, 2016 • 2

Last week, the Rosetta mission released a large quantity of science data to the worldwide public, including photos from the mission's close observation phase and the Philae landing.
