Japan SLIM Moon Lander Defies Expectations by Operating on 4th Lunar Day
JAXA controllers maintaining delicate balance on operational period which began 23 April, timing command / transmission with day-long interval to avoid overheating amid temperatures exceeding 100°C; Reactivation following 3rd lunar night (with temps near -170°C) was earlier in lunar day than previous cycles, resulting in brightest landscape / shortest shadows imaged during mission thus far; Near-equatorial location (13.3160°S, 25.2510°E) of SLIM lander mitigates temperature flux in comparison to near-polar site of Intuitive Machines Odysseus, which functioned 1 lunar day; Both Odysseus and SLIM contain lithium-ion batteries, however SLIM utilizes bespoke pouch cells, whereas Odysseus has COTS cells
