Phil Kaaret (ST12) is lead author on the paper which describes Chandra X-ray Observatory observations of the galaxy NGC 2366. Escape of Lyman continuum (LyC) emission from galaxies found in the early universe was essential for the reionization of the universe when the intergalactic medium (IGM) changed from being neutral gas to the ionized IGM that we observe today. Compact emission-line galaxies (LCGs) are the most abundant class of confirmed Lyman continuum (LyC) emitters and provide (relatively) nearby analogs of the galaxies found in the early universe. An optical integral field study of NGC 2366 revealed an outflow originating at a star cluster known as “knot B” that…

Timothy Lang (ST11) is the Principal Investigator and Aaron Kaulfus (ST11) is a Co-Investigator (Co-I) on a proposal titled “Using CYGNSS with a suite of spaceborne remote sensing datasets to probe tropical maritime cold pool evolution from space”, which was recently selected for funding by NASA. CYGNSS stands for Cyclone Global Navigation Satellite System, and the proposal seeks to combine CYGNSS and other scatterometer measurements of ocean winds using machine learning to detect and track cold pools (i.e., gust front winds) from tropical maritime convection throughout their lifetimes. This work will enable a more process-oriented look at how convectively driven cold poo…

Linda Krause and Heidi Haviland (ST13) along with Jeff Apple, Miguel Rodriguez-Otero (ES11), Kurt Dietz (ES52), and Gary Thornton (ES21) contributed to the Planetary Instrument Concepts for the Advancement of Solar System Observations (PICASSO) proposal LVACCS that was selected for funding. Omar Leon (University of Michigan) is the instrument suite PI. Electric charge accumulates on the lunar rovers and landers from ambient plasma, ionizing radiation, suprathermal charged particles, dust, and surface regolith. LVACCS will measure both the positive and negative charge, acts to discharge negative charge buildup, and actively charges the vehicle to a known positive potential…

Analyses suggest that microgravity does not significantly alter fundamental biochemical pathways in kidney cells, including metabolism of vitamin D. This finding could help researchers develop strategies to protect crew health on future missions and improve treatment of kidney-related diseases on Earth. Kidney Cell examined the effects of microgravity and other factors of space travel on kidney health. Previous reports suggested that changes in kidney cell metabolism of vitamin D plays a role in bone loss in microgravity, and this paper recommends additional study to determine if this most recent finding is consistent with extended (>6 months) exposure to mic…

The summer months are usually a time for teachers to take a break from the classroom and enjoy some well-earned rest. But at NASA’s Johnson Space Center in Houston, two experienced educators dedicated their summer vacations to learning how to enrich their students’ science, technology, engineering, and mathematics (STEM) education and inspire them to achieve their dreams. Johnson’s Office of STEM Engagement (OSTEM) welcomed Jerry “Denise” Dunn and Shawnda Folsom as full-time interns for the summer. Both women came to Johnson through the Oklahoma Space Grant Consortium, which not only supports students pursuing STEM careers but also provides curriculum enhancement…
