Long Lived In-situ Solar System Explorer (LLISSE) is a possible NASA payload on the Russian Venera-D mission to Venus. LLISSE uses new materials and heat-resistant electronics that would enable independent operation for about 90 Earth days.^[1]^[2] This endurance may allow it to obtain periodic measurements of weather data to update global circulation models and quantify near surface atmospheric chemistry variability.^[1] Its anticipated instruments include wind speed/direction sensors, temperature sensors, pressure sensors, and a chemical multi-sensor array. LLISSE is a small 20 cm (7.9 in) cube of about 10 kg (22 lb).^[1]^[3] The Venera-D lander may carry two LLISSE units; one would be battery-powered (3,000 h), and the other would be wind-powered.^[1]^[2]
