Delay of Astro-E2 Launch
Delay of M-V-6 launch
ISAS/JAXA announced that the launch of Astro-E2 scheduled in
January-February 2005 would take place no earlier than April 2005. The
delay is a result of JAXA's intention to focus all of its resources on
solving the solid rocket problems found in the solid booster (SRB-A)
of H-IIA vehicle.
Astro-E2 launch schedule
In JAXA, it is the most important issue to resume the SBR-A, which had
serious problems in the launch of H-IIA-6. Since the SBR-A and M-V are
based on the common technology of solid motors and produced by the
same industry, it has become clear that it should be difficult for
JAXA to keep both H-IIA SBR-A and M-V teams in parallel at JAXA as
well as at the industry.
In order to ensure the success of the H-IIA launch scheduled in
February 2005, JAXA has to muster all of its expertise on solid motors
from H-IIA and M-V teams. Therefore the preparation of M-V-6 at the
launch site which was scheduled to start from October 2004 is
cancelled. This means the launch of M-V-6 in the Japanese fiscal year
of 2004 has to be postponed into the next fiscal year.
The Astro-E2 satellite to be lifted off by M-V-6 is the retry
of the Astro-E, which could not be placed in orbit in February 2000
because of rocket problems. JAXA recognizes the strong desire of
scientists in the world community to achieve the science goals of
Astro-E2 and will try to investigate every possibility to launch M-V-6
as early as possible in the fiscal year 2005.
