Observations, Instrument Development, and Experiments

We perform observations from ground-based and space-born telescopes to better understand the origin of stars and planetary systems and support space missions. We had more successful Spitzer space telescope proposals than any other organization, we have performed observations from the Hubble space telescope and space mission spectrometers such as Cassini VIMS, and our scientists are so well respected that they chair and sit on observatory time allocation committees.

The SOFIA water vapor monitor

We develop instruments and detectors to improve the capabilities of ground based and airborn telescopes. This is possible thanks to our scientists expertise in IR observations and our highly specialized instrument development shop tailored to producing scientific equipment and rapid prototyping which has produced flight hardware for airborne and space use. The team of technicians has extensive expertise with high vacuum systems, cryogenics, and optics. But that’s not all…

Lab Facilities

Instrumentation for transmission and reflection spectroscopy from the Vacuum UV through the Far IR.

Ice Spectroscopy and photo-chemistry:

Facilities include High-vacuum cryogenic equipment to simulate space ices, from interstellar grains at 10 K to icy surfaces of planets, comets, and satellites in the outer Solar System.

Alexandrite, Nd/YAG, and dye lasers and associated optical instrumentation for the vaporization, and photo-luminescence, and spectroscopic analysis of materials.

Chromatography for the analysis of organic molecules from meteorites and simulation experiments.

SSA5
Gas-phase spectroscopy: A Pulsed slit discharge nozzle that produces ultracold, very low density gas and plasmas combined with a high sensitivity cavity ringdown spectrometer.

NASA Cassini mission news Titan Gets a Dune “Makeover”

Titan’s siblings must be jealous. While most of Saturn’s moons display their ancient faces pockmarked by thousands of craters, Titan Saturn’s largest moon, may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using […]

Ames Kepler mission news Kepler Mission Manager Update

It has been more than three-and-a-half-years since the Kepler mission launched in March 2009. The spacecraft has continued in its heliocentric, drift-away orbit and is now more than 45 million miles away from Earth. The Kepler project team has completed two science data downloads since the last update. The most recent data download on Jan. […]

Kepler Telescope May Have Found Most Earth-Like Planet Yet

SPACE http://www.space.com/19201-most-earth-like-alien-planet.html (1/10, Moskowitz) reports, “A possible alien planet discovered by NASA’s Kepler space telescope is the most Earth-like world yet detected beyond our solar system, scientists say.” If confirmed, the new planet would be 1.5 times the size of the Earth and would be located in its star’s habitable zone. Furthermore, Natalie Batalha, a […]

Paper on the Sutter’s Mill Meteorite Appears in “Science”
NASA Researchers Strike Scientific Gold With Meteorite

The Sutter’s Mill meteorite fell to ground on 22 April 2012 and shortly thereafter searches were instigated for samples by NASA-ARC and SETI personnel in cooperation with multiple volunteers from the public. These efforts resulted in the finding of a number of metoeritic stones that were subsequently analyzed using a variety of analytical techniques by […]
