Pasadena, CA – There has been a significant increase in the amount of water “pouring” out of comet 67P/Churyumov-Gerasimenko, the comet on which the Rosetta mission’s Philae lander touched down in November 2014.
The 2.5-mile-wide (4-kilometer) comet was releasing the earthly equivalent of 40 ounces (1.2 liters) of water into space every second at the end of August 2014. The observations were made by NASA’s Microwave Instrument for Rosetta Orbiter (MIRO), aboard the European Space Agency’s Rosetta spacecraft. Science results from the MIRO team were released today as part of a special Rosetta-related issue of the journal Science.

Pasadena, CA – Ten years ago, an explorer from Earth parachuted into the haze of an alien moon toward an uncertain fate. After a gentle descent lasting more than two hours, it landed with a thud on a frigid floodplain, surrounded by icy cobblestones.
With this feat, the Huygens probe accomplished humanity’s first landing on a moon in the outer solar system. Huygens was safely on Titan, the largest moon of Saturn.
The hardy probe not only survived the descent and landing, but continued to transmit data for more than an hour on the frigid surface of Titan, until its batteries were drained.

Pasadena, CA – The Beagle 2 Mars Lander, built by the United Kingdom, has been thought lost on Mars since 2003, but has now been found in images from NASA’s Mars Reconnaissance Orbiter.
A set of three observations with the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. They show that the lander survived its December 25th, 2003, touchdown enough to at least partially deploy its solar arrays.

Pasadena, CA – A new NASA satellite that will peer into the topmost layer of Earth’s soils to measure the hidden waters that influence our weather and climate is in final preparations for a January 29th dawn launch from California.
The Soil Moisture Active Passive (SMAP) mission will take the pulse of a key measure of our water planet: how freshwater cycles over Earth’s land surfaces in the form of soil moisture.
The mission will produce the most accurate, highest-resolution global maps ever obtained from space of the moisture present in the top 2 inches (5 centimeters) of Earth’s soils.
NASA’s Hubble Space Telescope takes image of Pillars of Creation that shows possible destructive side
Written by Tony Phillips
Washington, D.C. – Although NASA’s Hubble Space Telescope has taken many breathtaking images of the universe, one snapshot stands out from the rest: the iconic view of the so-called “Pillars of Creation.”
The jaw-dropping photo, taken in 1995, revealed never-before-seen details of three giant columns of cold gas bathed in the scorching ultraviolet light from a cluster of young, massive stars in a small region of the Eagle Nebula, or M16.
In celebration of its upcoming 25th anniversary in April, Hubble has revisited the famous pillars, providing astronomers with a sharper and wider view. Although the original image was dubbed the Pillars of Creation, the new image hints that they are also “pillars of destruction.”
Washington, D.C. – The Expedition 42 crew orbiting Earth on the International Space Station gets the opportunity to celebrate New Year’s Eve a whopping 16 times as it circles the globe at 17,500 miles an hour.
Commander Barry “Butch” Wilmore and his crew, which includes NASA’s Terry Virts, Russian cosmonauts Elena Serova, Alexander Samoukutyaev and Anton Shkaplerov, and European Space Agency astronaut Samantha Cristoforetti, say they plan to celebrate with fruit juice toasts.

Pasadena, CA – A fresh look at data collected by NASA’s Cassini spacecraft during its 2001 flyby of Jupiter shows that Europa’s tenuous atmosphere is even thinner than previously thought and also suggests that the thin, hot gas around the moon does not show evidence of plume activity occurring at the time of the flyby.
The new research provides a snapshot of Europa’s state of activity at that time, and suggests that if there is plume activity, it is likely intermittent.

Pasadena, CA – The European Space Agency’s orbiting Rosetta spacecraft is expected to come within four miles (six kilometers) of the surface of comet 67P/Churyumov-Gerasimenko in February of next year. The flyby will be the closest the comet explorer will come during its prime mission.
“It is the earliest we could carry it out without impacting the vitally important bound orbits that are currently being flown,” said Matt Taylor, the Rosetta project scientist from the European Space Research and Technology Center, Noordwijk, the Netherlands. “As the comet becomes more and more active, it will not be possible to get so close to the comet. So this opportunity is very unique.”
NASA reports data from Rosetta Orbiter show origin of Earth’s water not from comets like Comet 67P/Churyumov-Gerasimenko
Written by DC Agle
Pasadena, CA – The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids.
Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko. The findings were published today in the journal Science.
NASA’s Spitzer, Hubble and Herschel Space Telescopes observes Warm Gases stopping Galaxy from making new Stars
Written by Whitney Clavin
Pasadena, CA – Some like it hot, but for creating new stars, a cool cosmic environment is ideal. As a new study suggests, a surge of warm gas into a nearby galaxy — left over from the devouring of a separate galaxy — has extinguished star formation by agitating the available chilled gas.
The unique findings illustrate a new dimension to galaxy evolution, and come courtesy of the European Space Agency’s Herschel space observatory, in which NASA played a key role, and NASA’s Spitzer and Hubble space telescopes.
