LAUNCH OF SFU & GMS-5 / H-II LAUNCH VEHICLE TEST FLIGHT NO. 3
-------------------------------------------------------------

06:00 PM(JST)
March 18, 1995
NASDA H-II TF#3
LAUNCH TEAM

The National Space Development Agency of Japan (NASDA) launched
the third H-II Launch Vehicle test flight (H-II TF#3) from
Tanegashima Space Center with the Space Flyer Unit (SFU) and
Geostationary Meteorological Satellite-5 (GMS-5) at 05:01:00 JST
(=UTC+9h) PM on March 18, 1995 at the launch azimuth of 97 degrees.

The flight of the first and the second stages was normal, and the
guidance and control system functioned as planned. The SFU was
separated approximately 13 minutes 16 seconds after the launch,
and GMS-5, at 27 minutes 47 seconds after the launch. All flight
events of H-II TF#3 were completed.

INJECTION INTO ORBIT OF THE SPACE FLYER UNIT (SFU)
--------------------------------------------------

March 18, 1995
NASDA HQ, TOKYO

The data from SFU after the first revolution was received at 06:37 PM
(JST) on March 18 at the Sagamihara Operation Center, ISAS.

The data confirmed that SFU was injected into the proper orbit.

SFU will deploy the solar array paddle and its status will be
confirmed around 08:20 PM on March 20 at the Sagamihara Operation
Center, ISAS.

FLIGHT CONDITION OF THE GEOSTATIONARY METEOROLOGICAL SATELLITE (GMS-5)
----------------------------------------------------------------------

11:00 PM
MARCH 18, 1995
NASDA GMS-5/H-II TF#3
TRACKING & CONTROL TEAM

NASDA launched GMS-5 "HIMAWARI-5" at 05:01 PM (JST) on March 18, 1995
from Tanegashima Space Center. The data from the satellite after the first
revolution was received at 06:25 PM on March 18 at Madrid Tracking and
Data Acquisition Station.

The Data calculation confirmed that "HIMAWARI-5" was inserted into
the first transfer orbit as planned.

The first transfer orbit is as follows:

Apogee Altitude: 36669 km
Perigee Altitude: 329 km
Orbit Inclination: 25.1 degree
Period: 10 h 50 m

The command for the apogee kick motor firing will be transmitted at
09:57 on March 19 from the Tracking and Control Center at Tsukuba Space
Center.

SOLAR ARRAY PADDLE DEPLOYMENT OF THE SPACE FLYER UNIT (SFU)
-----------------------------------------------------------

March 18, 1995
NASDA HQ, TOKYO

The Sagamihara Operation Center, ISAS confirmed that the SFU normally
completed the solar array paddle deployment at 07:25 PM (JST) on
March 18, 1995. The SFU is functioning normally after the solar
array paddle deployment.

INJECTION ORBIT DETERMINATION OF THE SPACE FLYER UNIT (SFU)
-----------------------------------------------------------

March 18, 1995
NASDA HQ, TOKYO

Data calculation confirmed that SFU was placed in the designated
orbit.

The orbit determination is as follows:

Apogee Altitude: 336 km
Perigee Altitude: 322 km
Orbit Inclination: 28.45 degree
Period: 1 h 31 m

SFU functions normally.

SFU will maneuver to its mission orbit by firing its Orbit Change
Thruster (OCT) three times.
SFU will complete orbit transfer to its mission orbit around
March 21.

After orbit transfer completion, the SFU initial function testing
will be started.
