Animation of Akatsuki trajectory from 21 May 2010 to 31 December 2016.Akatsuki; Venus; Earth; Sun;Akatsuki ( あかつき, 暁, 'Dawn'), also known as the Venus Climate Orbiter ( VCO) and Planet-C, is a Japanese tasked to study the. It was launched aboard an on 20 May 2010, and failed to enter orbit around Venus on 6 December 2010. After the craft for five years, engineers successfully placed it into an alternative elliptical Venusian orbit on 7 December 2015 by firing its thrusters for 20 minutes.By using five different cameras working at several wavelengths, Akatsuki is studying the stratification of the atmosphere, atmospheric dynamics, and cloud physics. Astronomers working on the mission reported detecting a possible that occurred on Venus in December 2015. Contents.Mission Akatsuki is a Japanese orbiter mission currently studying the planet. Observations include cloud and surface imaging from an orbit around the planet with cameras operating in the infrared, visible and UV wavelengths to investigate the complex Venusian and elucidate the processes behind the mysterious atmospheric super-rotation. On Venus, while the planet rotates at 6 km/h at the equator, the atmosphere spins around the planet at 300 km/h.
Other experiments are designed to confirm the presence of and to determine whether occurs currently on Venus.Akatsuki is Japan's first planetary exploration mission since the failed Mars orbiter probe which was launched in 1998. Akatsuki was originally intended to conduct scientific research for two or more years from an elliptical orbit around Venus ranging from 300 to 80,000 km (190 to 49,710 mi) in altitude, but its alternate orbit had to be highly elliptical ranging between 1,000 km and 10,000 km at its nearest point and about 360,000 km at its farthest. This larger orbit takes 10 days to complete instead of the originally planned 30 hours. The budget for this mission is 14.6 billion ( US$174 million) for the satellite and ¥9.8 billion (US$116 million) for the launch. Spacecraft design The main is a 1.45 × 1.04 × 1.44 m (4.8 × 3.4 × 4.7 ft) box with two, each with an area of about 1.4 m 2 (15 sq ft).
Creation Of The Akatsuki
The solar arrays provide over 700 W of power while in Venus orbit. The total mass of the spacecraft at launch was 517.6 kg (1,141 lb). The mass of the science payload is 34 kg (75 lb).Propulsion is provided by a 500- (110 ) bi-propellant, - orbital maneuvering engine and twelve mono-propellant hydrazine reaction control thrusters, eight with 23 N (5.2 lb f) of thrust and four with 3 N (0.67 lb f).
It is the first spacecraft to use a ceramic retrofire thruster. The total propellant mass at launch was 196.3 kg (433 lb).Communication is via an 8 GHz, 20-watt transponder using the 1.6 m (5 ft 3 in) high-gain antenna. The high-gain antenna is flat to prevent heat from building up in it. Akatsuki also has a pair of medium-gain horn antennas mounted on turntables and two low-gain antennas for command uplink. The medium-gain horn antennas are used for housekeeping data downlink when the high-gain antenna is not facing Earth.
Instruments The scientific payload consists of six instruments. The launch of AkatsukiAkatsuki left the on 17 March 2010, and arrived at the 's Spacecraft Test and Assembly Building 2 on 19 March. On 4 May, Akatsuki was encapsulated inside the large of the rocket that launched the spacecraft, along with the, on a 6-month journey to Venus. On 9 May, the payload fairing was transported to the Tanegashima Space Center's Vehicle Assembly Building, where the fairing was mated to the H-IIA launch vehicle itself.The spacecraft was launched on 20 May 2010 at 21:58:22 from the Tanegashima Space Center, after being delayed because of weather from its initial 18 May scheduled target. Orbit insertion failure Akatsuki was planned to initiate orbit insertion operations by igniting the orbital maneuvering engine at 23:49:00 on 6 December 2010.
The burn was supposed to continue for twelve minutes, to an initial Venus orbit with an apoapsis of 180,000 to 200,000 km (110,000 to 120,000 mi), a periapsis of 550 km (340 mi), and a four-day.The orbit insertion maneuver was confirmed to have started on time, but after the expected blackout due to by Venus, the communication with the probe did not recover as planned. The probe was found to be in safe-hold mode, spin-stabilized state with ten minutes per rotation.
Due to the low communication speed through the low-gain antenna, it took a while to determine the state of the probe. JAXA stated on 8 December that the probe's orbital insertion maneuver had failed.
At a press conference on 10 December, officials reported that Akatsuki 's engines fired for less than three minutes, far less than what was required to enter into Venus orbit. Further research found that the likely reason for the engine malfunction was salt deposits jamming the valve between the helium pressurization tank and the fuel tank. As a result, engine combustion became oxidizer-rich, with resulting high combustion temperatures damaging the combustion chamber throat and nozzle. A similar vapor leakage problem destroyed the probe in 1993.As a result, the probe was in a heliocentric orbit, rather than Venus orbit. Since the resulting orbit had an orbital period of 203 days, shorter than Venus' orbital period of 225 days, the probe drifted around the Sun compared to Venus.Recovery efforts JAXA developed plans to attempt another orbital insertion burn when the probe returned to Venus in December 2015. This required placing the probe into 'hibernation' or to prolong its life beyond the original 4.5-year design.
JAXA expressed some confidence in keeping the probe operational, pointing to reduced battery wear, since the probe was then orbiting the Sun instead of its intended Venusian orbit.Telemetry data from the original failure suggested that the throat of its main engine, the orbit maneuver engine (OME) was still largely intact, and trial jet thrusts of the probe's onboard OME were performed twice, on 7 and 14 September 2011. However, the thrust was only about 40 newtons (9.0 lb f), which was 10% of expectations. Following these tests, it was determined that insufficient would be available for orbital maneuvering by the OME.
It was concluded that the remaining combustion chamber throat was completely destroyed by transient ignition of the engine. As a result, the selected strategy was to use four hydrazine thrusters, also called (RCS), to drive the probe into orbit around Venus. Because the RCS thrusters do not need oxidiser, the remaining 65 kg of oxidiser was vented overboard in October 2011 to reduce the mass of the spacecraft.Three peri-Venus orbital maneuvers were executed on 1 November, 10 and 21 November 2011 using the RCS thrusters. A total of 243.8 m/s was imparted to the spacecraft.

Because the RCS thrusters' specific impulse is low compared to the specific impulse of the OME, the previously planned insertion into low Venusian orbit became impossible. Instead, the new plan was to place the probe in a highly elliptical orbit with an apoapsis of a hundred thousand kilometers and a periapsis of a few thousand kilometers from Venus. Engineers planned for the alternate orbit to be prograde (in the direction of the atmospheric super-rotation) and lie in the orbital plane of Venus. The method and orbit were announced by JAXA in February 2015, with an orbit insertion date of 7 December 2015. The probe reached its most distant point from Venus on 3 October 2013 and had been approaching the planet since then. Orbit insertion.
Animation of Akatsuki 's trajectory around from 1 December 2015 to 14 February 2018Akatsuki After performing the last of a series of four trajectory correction maneuvers between 17 July and 11 September 2015, the probe was established on a trajectory to fly past Venus on 7 December 2015, when Akatsuki would make a maneuver to enter Venus orbit after a 20-minute burn with four thrusters that were not rated for such a hefty propulsive maneuver.
