Delta-X is a 5-year NASA Earth Venture Suborbital-3 mission to study the subsidence and growth of the Mississippi River Delta in the United States. 

Four subregions of Alaska (left) with example of lakes and ponds derived from PlanetScope imagery (right). Lake and pond extents include monthly climatological composites (May - September) and 3-year composites for 2019-2021. The inset for the Fairbanks (FB) region shows a close-up of the water extents overlain on sub-meter Esri base map imagery. The Yukon Flats (YF) inset shows variability in surface area of large lakes. The Delta Junction (DJ) inset shows seasonal changes in the area of small ponds. The Yukon-Kuskokwim Delta (YKD) inset shows the spatial variability of water body areas in this region and is an example of a 3-year composite.

CO2 Sounder instrument photographs. a) The aircraft rack with the new seed laser subsystem. b) The aircraft racks containing the laser power amplifiers and the lidar's detector subsystem. c) The lidar's transmitter and receiver telescope assembly, which is positioned over the nadir window assembly in the aircraft fuselage. The optical pulses from the fiber amplifiers, and the received optical signals are coupled via fiber optics. d) The instrument operator's console, with the control computer screens folded away (Abshire et al., 2018).
