Solar Contributions to Earth’s Oceans<\/a><\/p>\n
This was a large collaborative work combining laboratory studies and analysis of grains from Itokawa. The results suggest that much of the water in Earth’s oceans could have originated from water created from solar wind implantation onto rocky airless bodies, such as asteroids.<\/p>\n
The work has been picked up by a couple of national\/local news outlets:<\/p>\n

According to and informal survey of faculty and graduate students conducted by Ty Robinson<\/strong>: given the total number of NAU undergraduates involved in LSAMP (Louie Stokes Alliance ofr Minority Participation) in any given year, DAPS accounts for roughly 10% of all combined advising and mentoring, and about 20% of all research advising. These are strong numbers that indicate DAPS’ commitment to increasing diversity in STEM.

Space weathering of the 3 micron phyllosilicate feature induced by pulsed laser irradiation.<\/a><\/p>\n
This work is the first study to look at how the 3-micron absorption band is altered by simulated micrometeorite impacts in meteorite analogs that have undergone high degrees of aqueous alteration. This study suggests that, at least for the most aqueously altered asteroids, this spectral region may be extremely useful for determining the asteroid’s composition even if it
\nhas been heavily processed by space weathering.

The 2020 Decadal Survey on Astronomy and Astrophysics was released Accordion Closed<\/span><\/h4>\n <\/span>\n <\/div>\n <\/a>\n
\n \n\n
The report highlighted direct imaging of potentially Earth-like exoplanets in the habitable zones of Sun-like stars as a key science goal for the coming decade(s). To support this, the Decadal recommended NASA create a new Great Observatories Mission and Technology Maturation Program, whose purpose is to develop technologies needed for pan-decadal large missions. The first mission recommended to go through this development is a ~6m ultraviolet-optical-infrared space telescope capable of characterizing exo-Earths (ie, halfway between the HabEx 4m concept and the LUVOIR-B 8m).<\/p>\n
Ty Robinson<\/strong> had multiple scientific results showcased as figures in the 2020 Decadal Survey on Astronomy and Astrophysics on topics of exoplanet direct imaging and Solar System analogs for exoplanet observations. He’ll be heavily involved in this new program as the mission matures over the next decade(s).

We still have a few pending proposals, so we don’t have the final results yet, but so far we have five selections in the past two years. You might recall that last year NAU tied for first place in the country for the number of NASA FINESST fellows selected (UA and NAU had three each).

Department chair David Trilling<\/strong> said the work Kramer has done as an undergraduate researcher at NAU is helping to define this emerging sub-industry. “It is not an exaggeration to say that without Daniel’s terrific work, we would not have been able to submit several funding proposals for NASA and NSF,” Trilling said. “In the next 15 years, because of his work, I fully expect that NAU will be the world leader in this particular sub-topic.”

NAU did really, really well. Three faculty were on selected proposals: David Trilling<\/strong> (PI of one proposal, co-PI of another); Cristina Thomas<\/strong> (CoI on 3 proposals); and Josh Emery<\/strong> (CoI on 3 proposals).<\/p>\n
There were 22 proposals selected in the sub-area of Solar System Science, and this group of faculty are part of the proposing team for 7 of those 22 (that’s 32%).<\/p>\n
These 22 selected proposals together represent 376 hours of telescope time, and this group of faculty are part of the proposing team for 244 of those hours (that’s 65%). Wow — NAU is part of 65% of all JWST Solar System science time allocated in Cycle 1.<\/p>\n
Josh points out that PhD student Audrey Martin<\/strong> is a CoI on one of the selected proposals that he is also on, and that she contributed heavily to the proposal by writing the section dedicated to the MIRI instrument.

PhD Student, Patrick Tribbett and Mark Loeffler published a paper Accordion Closed<\/span><\/h4>\n <\/span>\n <\/div>\n <\/a>\n

in Surface Science<\/strong>, where they used their laboratory data to show that existing models over predict the sputtering of O2 from H2O-ice by between a factor of five and eight at temperatures relevant to Europa. They were able to make an empirical correction to the existing model to match our new and other previous laboratory data. This correction should allow one to more accurately predict how efficiently exospheres can be produced by energetic ion irradiation of the surface H2O-ice on icy moons in our solar system.<\/p>\n
