Preparation for and performance of a Pseudomonas aeruginosa biofilm experiment on board the International Space Station by Flores, Pamela, Schauer, Rylee, McBride, Samantha A., Luo, Jiaqi, Hoehn, Carla, Doraisingam, Shankini, Widhalm, Dean, Chadha, Jasmin, Selman, Leah, Mueller, Daniel Wyn, Floyd, Shannon, Rupert, Mark, Gorti, Sridahr, Reagan, Shawn, Varanasi, Kripa K., Koch, Christina, Meir, Jessica U., Muecklich, Frank, Moeller, Ralf, Stodieck, Louis, Countryman, Stefanie, Zea, Luis

“…For this, 288 bacterial samples were prepared prior to the launch of the Northrop Grumman CRS-12 mission from NASA's Wallops Flight Facility. The samples were integrated into the spaceflight hardware, BioServe's Fluid Processing Apparatus (FPA), packed in sets of eight in Group Activation Packs (GAP). …”

Mercury: Mid‐infrared (3–13.5 μm) observations show heterogeneous composition, presence of intermediate and basic soil types, and pyroxene by Sprague, A, Emery, J, Donaldson Hanna, K, Russell, R, Lynch, D, Mazuk, A

“… Abstract— The Aerospace Corporation's broadband array spectrograph system (BASS) mounted on the NASA infrared telescope facility (IRTF) on Mauna Kea, Hawaii was used to obtain spectral measurements of Mercury's thermal emission on 1998 March 21 (45–85° longitude), and on 1998 May 12 (68–108° longitude). …”

Characterizing K2 Candidate Planetary Systems Orbiting Low-mass Stars. I. Classifying Low-mass Host Stars Observed during Campaigns 1–7 by Dressing, Courtney D., Schlieder, Joshua E., Charbonneau, David, Knutson, Heather A., Vanderburg, Andrew, Sinukoff, Evan, Newton, Elisabeth R

“…We present near-infrared spectra for 144 candidate planetary systems identified during Campaigns 1–7 of the NASA K2 Mission. The goal of the survey was to characterize planets orbiting low-mass stars, but our Infrared Telescope Facility/SpeX and Palomar/TripleSpec spectroscopic observations revealed that 49% of our targets were actually giant stars or hotter dwarfs reddened by interstellar extinction. …”
