Pipcard Posted August 22, 2022 Author Share Posted August 22, 2022 (edited) The Ame-no-Uzume Venus Mission was named after the Japanese goddess associated with dawn and merriment, as a successor to the Akatsuki ("Dawn") Venus orbiter mission. It would involve a total of 6 (2 + 4) launches. In 2037, the Venus Habitat Module and Venus Ascent Vehicle would depart Earth to enter a 300 km orbit around their destination. The crew would launch in 2039 and ride on the Venus Transport Vehicle. Several transfer stages, heavier and longer compared to their Mars-bound predecessors, would be launched by the H-Z 222L. The crew would then transfer from the VTV to the VHM/VAV, which would deploy an inflatable heat shield and enter the atmosphere of Venus, releasing parachutes and a large balloon* that would allow the vehicle to float over 50 km above the extreme conditions on the surface. Two astronauts would enter the Venusian atmosphere while one would stay in orbit. After about 30 days, the two-stage VAV would drop from the VHM and launch back to orbit, meeting up with the VTV. Once returning to Earth in 2040, Earth Arrival Vehicle would then slow down to reduce G-forces upon re-entry. * from KerBalloons with modified configs Spoiler 2037-09-25 - The first launch (H-Z 204L) carried the Venus Habitat/Ascent Vehicle with the Venus Orbit Stage (3x LE-7-R, 3x LE-5B-3), which had a mass of over 400 tonnes and entered a 400 km parking orbit. The VAV had a Raptor engine on the first stage, with 3x methane RL10s on the second stage. The solar arrays were slightly smaller than the Mars mission due to Venus being closer to the Sun; however, the Venus Transfer Vehicle (2039-2040) would need to go as far as the orbit of Mars during the return trip. 2037-10-16 - A Zeta rocket launched from Uchinoura Space Center with three Kodama-X Data Relay and Tracking Satellites to Venus. Spoiler 2037-10-19 - An H-Z 222L launched the Earth Departure Stage (8x LE-7-R) for the Ame-no-Uzume Venus Habitat/Ascent Vehicle, docking just a few hours later. The total mass of the stack was about 1180 t. Spoiler Edited August 22, 2022 by Pipcard Quote Link to comment Share on other sites More sharing options...
