H-IIA Launch Vehicle No. 15 Mission

The H-IIA Launch Vehicle No. 15 is a "H2A202" model with two solid rocket boosters (SRBs). The fairing design is 4S (4 meters in diameter.) Mitsubishi Heavy Industries, Ltd. is in charge of the launch service of the H-IIA.
The main mission of the H-IIA Launch Vehicle No. 15 is to inject its main payload, the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT), into its scheduled orbit, the sun-synchronous subrecurrent orbit, then to inject seven other piggyback payloads into their respective orbits one by one.

IBUKI Injection Orbit
Sun-synchronous subrecurrent orbit at a perigee altitude of 667 km, apogee altitude of 683 km, and inclination of 98.0 degrees

Six piggyback satellites,  selected through public tender, and one JAXA small satellite, are scheduled to be launched by the H-IIA Launch Vehicle No. 15 alongside the "IBUKI" satellite.
The piggyback payload launch utilises the excessive launch capability of the rocket to launch small satellites that are made by a private company or university.


"KAGAYAKI"
SORUN CORPORATION
The aim of the project is to connect the dreams of disabled children with space.
The satellite features the following:
- Autonomous onboard control system
- Inflatable deployable boom
- Mission (debris detection, Aurora electric current observation, Design for reducing residual magnetism)

"STARS"
Kagawa University
This aims to conduct a tether space robot technology demonstration.
A verification of tether extension by parent and child satellites will also be carried out.

"KKS-1"
Tokyo Metropolitan College of Industrial Technology
The goal is to perform a demonstration of the micro cluster and three axis attitude control functions.

"PRISM"
The University of Tokyo
This satellite will conduct an experiment on earth image acquisition by using an expandable refracting telescope.
A technological demonstration and verification of the ultra-small satellite bus made of commercial products will also be conducted.
It will also provide various amateur radio services

"SOHLA-1"
ASTRO TECHNOLOGY SOHLA
This will contribute to more vibrant activities for local industries.
It will measure thunder and lightening.

"SPRITE-SAT"
Tohoku University
The project will observe the sprite phenomenon and gamma radiation of the earth's origin.

Small Demonstration Satellite-1 (SDS-1)
Japan Aerospace Exploration Agency
This satellite has a multi-mode integrated transponder.
It will carry out on-orbit verification of the space wire demonstration module.
On-orbit verification of a cutting-edge micro processor will also be performed.

Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency decided to reschedule the launch of the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT) aboard the H-IIA Launch Vehicle No. 15 (H-IIA F15) to January 22, 2009 (Japan Standard Time, JST) from the Tanegashima Space Centre.
However, due to cloudy conditions at the launch site, JAXA has decided to reschedule the launch date to January 23 (JST).
The launch time is between 12:54 p.m. and 1:16 p.m. on the 23rd (JST.).

JAXA will continue to monitor the weather conditions to make a final decision of the launch time on January 23.

Launch postponement of IBUKI/H-IIA F15
The launch of the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT) by the H-IIA Launch Vehicle No. 15 (H-IIA F15) was decided to be postponed as bad weather is forecast around the time of the countdown operations staging one day prior to the launch day.
The launch was originally scheduled for January 21, 2009 (Japan Standard Time). The new launch date will be January 22, 2009, or later.
JAXA is carefully monitoring the weather conditions to determine the date.

Japans first satellite to monitor global greenhouse gas emissions is to launch this week.
Industries like transport account for nearly a quarter of human CO2 emissions, and is a literal by-product of global economic growth, but UN Climate Control Chief Yvo de Boer says 21st monitoring often remains distinctly ancient, so Japan's "Ibuki" satellite will help the fight.

A Japanese H-2A rocket will launch the GOSAT satellite from the Tanegashima launch site on the 21st January, 2009.
The launch window is between 03:54 to 04:16 GMT.
