Since August 2014, the Rosetta spacecraft has been orbiting Comet 67P/Churyumov-Gerasimenko, providing an unprecedented look at an active comet as it moves closer to the Sun in its orbit. As expected, the level of activity increased the closer the comet was to the Sun, with jets of water vapor, gas, and dust becoming bigger and more […] More

A Perfect Day for Sunbathing: A Year After Its Arrival, Rosetta Observes Comet 67P at Perihelion
Just over a year after it reached Comet 67P/Churyumov–Gerasimenko, the European Space Agency’s (ESA) Rosetta spacecraft passed another milestone early Thursday, Aug. 13, when it became the first orbiting spacecraft to observe a comet at perihelion, its closest point to the Sun. ESA announced that the exact moment of perihelion occurred at 02:03 GMT when […] More

Rosetta and Philae Capture First Detailed Magnetic Measurements of a Comet Nucleus
Europe’s history-making cometary explorers—Rosetta and Philae—have captured the “first ever detailed measurements of the magnetic properties of a comet nucleus” in our Solar System and found that their target comet 67P/Churyumov-Gerasimenko is “not magnetized,” according to the research team leading the project.

Rosetta Team Completely Rethinking Comet Close Encounter Strategy
The operations team leading Europe’s fabulously successful Rosetta mission to comet 67P/Churyumov-Gerasimenko is now “rethinking” the strategy on how they will approach the spewing ice ball during future flybys, after impacts from a hail of debris strikes caused the probe to be “confused” and then enter “safe mode” and shut down the science instruments during […] More

Comet Debris Causes Significant Navigation Issues During Rosetta’s Latest Close Flyby
Impacts from cometary debris caused several significant navigation related issues for Europe’s Rosetta orbiter as it flew within 14 kilometers (8.7 miles) of the surface of comet 67P/Churyumov-Gerasimenko during the probe’s most recent close encounter in late-March. The high gain antenna drifted, the star trackers were confused, and the spacecraft went into “safe mode,” which […] More

Rosetta Makes First Detection of Cometary Molecular Nitrogen, Seeks Signals From Philae Lander
Rosetta, humankind’s first spacecraft to orbit a comet, has now made the first detection of molecular nitrogen (N2) at a comet. Meanwhile, the European Space Agency (ESA) probe continues searching for signals from Philae, humankind’s first probe to land on the surface of a comet, named 67P/Churyumov-Gerasimenko. The discovery of molecular nitrogen “provides important clues about […] More

ESA’s Rosetta Spacecraft Begins Search for Signs of Life From Philae
Could it be possible that a lander the size of a washing machine, thought to be lost nearly four months ago following its passing into shadow, might still be generating signals? Beginning today, the European Space Agency’s (ESA) Rosetta spacecraft, orbiting Comet 67P/Churyumov-Gerasimenko, began its search for signs of life from its lander, Philae, which […] More

Rosetta’s Valentine’s Day Flyby Encounter Produces Stunning Comet Close-Ups
The Rosetta spacecraft swooped in for a cosmic swoon on Valentine’s Day, Feb. 14, and the close encounter produced stunning high-resolution close-ups and additional observations of the backside, head, and other regions of the comet’s nucleus and coma, which the probe is escorting in a dance around the Sun and studying as it changes over […] More

Rosetta Captures Spectacular Comet Jets Blasting Away Ahead of Valentine’s Day Encounter
Europe’s Rosetta spacecraft has captured the most spectacular imagery yet of comet 67P/Churyumov-Gerasimenko spewing forth gas and dust during what the team dubbed “The Last Waltz” as the frigid celestial body inexorably heats up, and the probe was successfully retargeted for a super-close encounter on Valentine’s Day.

Rosetta Reveals Cracked Comet Covered With Dust and Spewing Pits
Scientists leading Europe’s Rosetta orbiter mission have discovered a wondrous array of rugged surface terrain, mysterious cracks, and jet spewing pits at the dust covered Comet 67P/Churyumov–Gerasimenko, following the spacecraft’s arrival on Aug. 6, 2014, after a decade-long interplanetary journey of some 500 million kilometers (300 million miles) from Earth. Rosetta is on a mission […] More

Rosetta Observations Spark Debate on Origin of Earth’s Water
Comets? Asteroids? Or what? One of the most basic questions driving Astronomy and Space Exploration is: Where did the water for Earth’s oceans come from? The answer to the question of the origin of Earth’s water has the most fundamental implications for the formation of Earth and the origin of life on Earth, and is […] More
