NASA’s Curiosity rover used onboard LEDs to illuminate the Nevado Sajama drill site at night, with Mastcam and MAHLI capturing details of freshly exposed rock that are hard to see in daylight, including smoother drill walls and subtle layering. This targeted nighttime imaging expands geological insight and demonstrates NASA’s adaptable use of aging hardware to extract high-value data.
ESA’s daylight-focused Sentinel-2A was activated during night passes and produced unexpectedly clear images of gas flares in Qatar and Iraq, a wildfire in India, and fishing boats off South Korea, demonstrating potential for nighttime Earth observation and informing future mission requirements as the Copernicus program progresses with additional Sentinel-2 satellites.
ESA tested Sentinel-2A’s ability to image at night, obtaining useful nighttime observations of gas flares, wildfires, city lights and fishing boats, to inform the design of the future Sentinel-2 Next Generation mission while Sentinel-2B and -2C continue core operations.
