Searching for Life on Enceladus

I am proposing a mission to orbit and then land on Enceladus to search for evidence of life. With a few fly-bys, the Cassini probe has already found organic molecules which could be precursors and products of living organisms. My probe will collect more information. It will first orbit, passing repeatedly through the geysers rising above the icy surface and collecting many water samples spewing from the subterranean oceans. It will search for safe landing spots on the south pole near the geysers. After several years in orbit, the probe will land near a geyser and lower instruments with powered legs, hooks, infrared cameras, radar, and Lidar into the crevasse. It will collect additional water samples and examine them for evidence of life using NASA’s new Ocean Worlds Life Surveyor device. A radioisotope power system (RPS) like the multi-mission radioisotope thermoelectric generator will be needed because Enceladus is approximately 10 times as far from the sun as Earth and only receives 1% of the solar energy that we do, so it is very dark and cold. An RPS will provide power for instruments and heat to keep instruments at stable temperatures over decades. My power is perseverance: trying again and learning to improve when things don’t work at first. For example, I might not be able to fit a Lidar system on my probe due to its weight. Then I would need to develop a lighter Lidar, replace Lidar with a different instrument like radar, or invent a new instrument.
