Figure caption: Changes in sample surface texture during an annealing experiment. The process consisted of cooling until freezing, warming to 95 K to melt the sample, and repeating for three rounds. Cycle 1 expanded and formed cryodomes; Cycle 2 took on the expanded/flat morphology and retained a small quantity of liquid; Cycle 3 showed almost no sign of surface roughening and remained mostly liquid.

Figure caption: Top row: calibrated images of small bodies acquired by ESA’s Rosetta, JAXA’s Hayabusa, and NASA’s OSIRIS-REx missions, from left to right. Gray scale indicates the reflectance of the surface. Bottom row: EOI measured on the same images. The low and high values of entropy match the distribution of rough and smooth terrains on all objects. All images use the same color scale. Qualitatively, 67P and Itokawa display different types of terrains, while Bennu’s surface is more uniform. All data are publicly available; see Appendix A.

Figure caption: Dimorphos, the target of the DART impact, oriented with its north pole toward the top of the image. DART’s onboard DRACO imager captured this image from a distance of 68 km. Dimorphos is 177 m in length along its long axis. This figure was windowed and rotated from image dart_0401930039_14119_01_raw, which was identified in real time as the last frame to contain all of the lit body of Dimorphos in the field of view (Daly et al. 2023b).

The LLNV results for the ternary system are also included, with the solid line representing the composition of the L phase and the dashed line denoting the LN phase. The presence of the vapor phase is removed, showing only the condensed phases. Subscripts: N = nitrogen-rich, M = methane-rich, E = ethane-rich.

Figure caption: N2 dissolution into the LV equilibrium system as a function of temperature. The greater the CH4 N2-free mole fraction (r  M ) and the lower the temperature, the more N2 dissolves into the system. Experimental data are presented with uncertainties ±0.03 N2 and ±0.5 K. The bubble-point curves and three-phase LLNV, SELV, SELLN, and SLNV boundaries are the results from CRYOCHEM 2.0 (CC 2.0) calculations. Points F and G are in the four-phase SELLNV equilibrium at 82.53 K and connected by the vertical dashed line. The horizontal dashed line delineates liquid composition; liquid above the line is N2-rich (LN), while liquid below it does not have a dominant species (L).

Figure caption: The ternary CH4–C2H6 + N2 composition phase diagrams at 1.5 bars and at (a) 95 K and (b) 90 K. The black filled circles are the measured data from this work, with compositional uncertainties of ±0.03 r  M . The blue open circles and red filled diamonds are from the literature. Green dashed lines at 95 K are typical tie lines connecting equilibrium compositions in liquid and vapor. Brown dotted lines at 90 K are the +N2 cooling paths (constant r  M  as indicated on each of the lines).

Figure caption: Raman spectra associated with the 0.79 r  M  results in Figure 6, which is a composition that is representative of the behavior in the SELVNV region of the pseudo-binary phase diagram. Panel (a) shows the spectral range used for deriving compositions (2300–3000 cm−1) from starting at 95 K and traveling down the +N2 cooling path to 82.5 K. Panels (b) and (c) are zoomed-in regions of the N2 peak and CH4/C2H6 peaks, respectively. The dotted lines mark the peak centers at 95 K, and, unlike the spectra in the 0.29 r  M  sample, all three noted peaks blueshift with decreasing temperature and increasing N2 content.

Panels (b) and (c) are zoomed-in regions of the N2 peak and CH4/C2H6 peaks, respectively. The dotted lines mark the peak centers at 95 K and show that there is minimal shifting despite decreasing temperature and increasing N2 content.

Figure caption: Effects of N2 exsolution on ice morphology in four different C2H6 +N2 samples. The primary formations seen during experiments were (a) one larger cryodome, (b) multiple smaller cryodomes, (c) flat/expanded, and (d) flat/undisturbed. T step indicates the temperature step during which ice formed, and t settling is the amount of time the sample was allowed to settle between each temperature step previous to ice formation.

Figure caption: Evidence of N2 exsolution from a C2H6 + N2 sample. Top: the vapor pressure rose in the cell shortly after the temperature was lowered to 88 K, which incited freezing. Bottom: normalized Raman spectra of the sample pre- and post-freezing, shown in red and blue, respectively. The inset demonstrates a complete exsolution of N2, while the peaks between 2850 and 3000 cm−1 indicate that all, or nearly all, of the C2H6 solidified.
