It would have been a heroic coda to an already ambitious, historic mission, but alas, it was not meant to be. For the past few months, […]

Rosetta Makes First Detection of Cometary Molecular Nitrogen, Seeks Signals From Philae Lander

Rosetta has made the first detection of molecular nitrogen at a comet. The results provide clues about the temperature environment in which Comet 67P/Churyumov–Gerasimenko formed. Credit: ESA/ATG medialab; comet: ESA/Rosetta/NavCam – CC BY-SA IGO 3.0

Rosetta, humankind’s first spacecraft to orbit a comet, has now made the first detection of molecular nitrogen (N2) at […]

Rosetta Reveals Cracked Comet Covered With Dust and Spewing Pits

Comet 67P/Churyumov–Gerasimenko regional maps The 19 regions identified on Comet 67P/Churyumov–Gerasimenko are separated by distinct geomorphological boundaries. Following the ancient Egyptian theme of the Rosetta mission, they are named for Egyptian deities. Credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA

Scientists leading Europe’s Rosetta orbiter mission have discovered a wondrous array of rugged surface terrain, mysterious […]

Rosetta Observations Spark Debate on Origin of Earth's Water
