E modulus (a) PEGDA and (b) PEGDA-GO hydrogels with different PBS content, comparing ground and flight data. The error bars indicate the minimum and maximum values. The line in the middle presents the median value. Outliners (anything higher or lower than 1.5 times the interquartile range) are presented with a diamond shape. *p < 0.05, n.s. = not significant (p > 0.05); Stress–strain curve of swollen (c) PEGDA and (d) PEGDAGO hydrogels. Comparison between ground and flight after the 4th spray. The test is stopped at a maximum force of ~6.5 N.
