Pasadena, CA – As the European Space Agency’s spacecraft Rosetta is slowly approaching its destination, comet 67P/Churyumov-Gerasimenko, the comet is again proving to be full of surprises.
New images obtained by OSIRIS, the onboard scientific imaging system, confirm the body’s peculiar shape hinted at in earlier pictures. Comet 67P is obviously different from other comets visited so far.
Washington, D.C. – The first humans who will step foot on Mars are walking the Earth today. It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era.
We stand on a new horizon, poised to take the next giant leap—deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond.

Pasadena, CA – Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA’s Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory. Herschel is a European Space Agency mission with important NASA contributions.
Energetic jets, which blast from Messier 106′s central black hole, are heating up material in the galaxy and thus making it glow, like the ingredients in a firework. The jets also power shock waves that are driving gases out of the galaxy’s interior.

Washington, D.C. – Scientists analyzing data from NASA’s Cassini mission have firm evidence of an ocean inside Saturn’s largest moon, Titan, which might be as salty as the Earth’s Dead Sea. The findings are published in this week’s edition of the journal Icarus.
“This is an extremely salty ocean by Earth standards,” said the paper’s lead author, Giuseppe Mitri of the University of Nantes in France. “Knowing this may change the way we view this ocean as a possible abode for present-day life, but conditions might have been very different there in the past.”
NASA reports Rosetta spacecraft detects water vapor coming from target Comet 67P/Churyumov-Gerasimenko
Written by DC Agle
Pasadena, CA – Comet 67P/Churyumov-Gerasimenko is releasing the Earthly equivalent of two glasses of water into space every second. The observations were made by the Microwave Instrument for Rosetta Orbiter (MIRO), aboard the European Space Agency’s Rosetta spacecraft on June 6th, 2014.
The detection of water vapor has implications not only for cometary science, but also for mission planning, as the Rosetta team prepares the spacecraft to become the first ever to orbit a comet (planned for August), and the first to deploy a lander to its surface (planned for November 11th).

Pasadena, CA – A combined NASA and European Space Agency (ESA)-funded study has found firm evidence that nitrogen in the atmosphere of Saturn’s moon Titan originated in conditions similar to the cold birthplace of the most ancient comets from the Oort cloud.
The finding rules out the possibility that Titan’s building blocks formed within the warm disk of material thought to have surrounded the infant planet Saturn during its formation.

Pasadena, CA – Less than half the distance between Earth and moon separates Rosetta from its destination, comet 67P/Churyumov-Gerasimenko. The European Space Agency’s (ESA) spacecraft will become the first to orbit a comet and land a probe on its nucleus. It is beginning observations and sending science data back to Earth.
Recent images from Rosetta’s Onboard Scientific Imaging System (OSIRIS) indicate that the comet is currently at rest — no longer showing signs of an extended dust coma surrounding its nucleus.

Pasadena, CA – As NASA’s Cassini spacecraft zooms toward Saturn’s smoggy moon Titan for a targeted flyby on June 18th, mission scientists are excitedly hoping to repeat a scientific tour de force that will provide valuable new insights into the nature of the moon’s surface and atmosphere.
For Cassini’s radio science team, the last flyby of Titan, on May 17th, was one of the most scientifically valuable encounters of the spacecraft’s current extended mission.
NASA says Herschel Space Observatory has discovered Giant Weird Ring Structure along with growing Stars
Written by Whitney Clavin
Pasadena, CA – The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538.
The observations have revealed numerous clumps of material, a baker’s dozen of which may evolve into the most powerful kinds of stars in the universe. Herschel is a European Space Agency mission with important NASA contributions.

Washington, D.C. – A spacecraft from Earth is about to do something no spacecraft has ever done before: orbit a comet and land on its surface.
Right now, the European Space Agency’s Rosetta probe is hurtling toward Comet 67P/Churyumov-Gerasimenko. The spacecraft’s mission is to study the comet at close-range as it transforms from a quiet nugget of ice and rock, frozen solid by years spent in deep space, to a sun-warmed dynamo spewing jets of gas and dust into a magnificently evolving tail.
News flash: The metamorphosis has begun.
