Abstract Japanese Venus Climate Orbiter/AKATSUKI was proposed in 2001 with strong support by international Venus science community and approved as an ISAS (The Institute of Space and Astronautical Science) mission soon after the proposal. The mission life we expected was more than two Earth years in Venus orbit. AKATSUKI was successfully launched at 06:58:22JST on May 21, 2010, by H-IIA F17. After the separation from H-IIA, the telemetry from AKATSUKI was normally detected by DSN Goldstone… Expand
AKATSUKI returns to Venus
Abstract AKATSUKI is the Japanese Venus Climate Orbiter that was designed to investigate the climate system of Venus. The orbiter was launched on May 21, 2010, and it reached Venus on December 7,Expand
Hesperos: A geophysical mission to Venus
The Hesperos mission proposed in this paper is a mission to Venus to investigate the interior structure and the current level of activity. The main questions to be answered with this mission areExpand
Future of Venus Research and Exploration
Despite the tremendous progress that has been made since the publication of the Venus II book in 1997, many fundamental questions remain concerning Venus’ history, evolution and current geologic andExpand
Venus Atmospheric Thermal Structure and Radiative Balance
From the discovery that Venus has an atmosphere during the 1761 transit by M. Lomonosov to the current exploration of the planet by the Akatsuki orbiter, we continue to learn about the planet’sExpand
We report Venus image observations around the two maximum elongations of the planet at 2015 June and October. From these images we describe the global atmospheric dynamics and cloud morphology in theExpand
A review of Lighter-than-Air systems for exploring the atmosphere of Venus
Abstract Venus and Earth are called sister-planets considering their similar size, and the density. It is the nearest planet to the Earth in the solar system. From 1960s various missions forExpand
Venus: key to understanding the evolution of terrestrial planets
Why are the terrestrial planets so different? Venus should be the most Earth-like of all our planetary neighbours. Its size, bulk composition and distance from the Sun are very similar to those ofExpand
Cloud top structure of Venus revealed by Subaru/COMICS mid-infrared images
Abstract We have investigated the cloud top structure of Venus by analyzing ground-based images taken at the mid-infrared wavelengths of 8.66 μm and 11.34 μm. Venus at a solar phase angle of ∼90°,Expand

The Trajectory Control Strategies for AKATSUKI Re-Insertion into the Venus Orbit
Abstract: The Japanese Venus explorer "Akatsuki (PLANET-C)", which now rotates about the Sun, will approach to Venus again in 2015. For the Venus orbit re-insertion, several trajectory strategiesExpand
Lightning Detection by LAC Onboard the Japanese Venus Climate Orbiter, Planet-C
Lightning activity in Venus has been a mystery for a long period, although many studies based on observations both by spacecraft and by ground-based telescope have been carried out. This situationExpand
