Vietnamese cosmonaut
• Space Technology has been introduced into Vietnam since
1980 by the UNDP’s projects to promote utilization satellite
data in survey, and particularly by the joint Soviet Union Vietnam space flight.
• Cosmonaut Pham Tuan joined People’s Army of Viet Nam Air
Force since 1965. On the night of December 27, 1972, he shot
down a US B-52 bomber circling over the Ha Noi sky,
becoming the first person ever to do so.
• With his great military exploit, Pham Tuan was selected to
take part in the joint Vietnam–Soviet Union flight for the
study of space for peaceful purposes.

Born on February 14, 1947, in Thai
Binh province (VN).
Pham Tuan along with soviet
cosmonaut Viktor Gorbatko was
launched from Baikonur Cosmodrome
on July 23, 1980 on board Soyuz 3.
They were to service the Salyut 6
station. During his time in orbit Pham
Tuan performed experiments on the
melting of mineral samples in
microgravity and carried out plant
experiments on azola. The National
Centre for Scientific Research of
Vietnam( now renamed VAST) was
responsible to prepare these
experiments.
Was the first Vietnamese
cosmonaut, the first Asian in the
space.
Currently, Lieutenant General Pham
Tuan is the Head of National Defense
Industry Agency.

since 1968.
Doctorate of Philosophy in Applied
Physics from Yale University in 1977.
Was payload specialist crew member
on the STS-50/US Microgravity Lab1 Space shuttle in 1992.
Was the first Vietnamese-American
cosmonaut.
Published over 40 reviewed articles
and authored as many conference
papers in the areas of Fluid Dynamics,
Acoustics, Materials Science and
Microgravity science and technology.

Remote Sensing
• So far, there are many RS departments in:
;VAST: Institute of Physics, Institute of Geology, Institute
of Geography, Institute of Oceanography, etc.
;Ministry of Agriculture and Rural
Development (MARD): Forest Inventory and Planning
Institute (FIPI), National Institute of Agricultural Planning and
Projection (NIAPP), etc.
;Ministry of Natural Resources and
Environment (MONRE): Remote Sensing
Center (RSC).
Remote Sensing
• The Ministry of Science and Technology
(MOST) is requested to draft “ The Master
Plan for application and development of
remote sensing technology in Vietnam up to
year 2010”. The draft of the Master Plan is
submitted to the Government for approval.
• The 26th Asian Conference on Remote Sensing
ACRS2005 will be held in Hanoi on 7-11
November 2005 (http:// www.acrs2005.ac.vn).
VINASAT project
• Currently, Viet Nam spends about $8-10
million annually to transmit and receive
signals via foreign –owned satellites.
• The Vietnam Post and Telecommunication
Corporation (VNPT) has leased transponder
from ASIASAT-2 for VSAT network
development.
VINASAT Project
• The Vietnam Television (VTV) leased
transponder of Thailand’s Thaicom and
Russia’s Intersputnik.
• The Voice of Vietnam radio, Vietnam
Aviation Department and Vietsopetro leased
transponder of Indonesia’s Palapa satellite and
of Intersputnik satellite.
VINASAT Project
• Vietnam’s growing economy required significant
increases in demand for telecomunications.
services.Viet Nam is currently in need of a medium –
size satellite with 20-28 transponders. The satellite
must ensure adequate coverage for the television,
aviation, communications and petroleum sectors. The
expected orbital slot for VINASAT is 1320 East.
• Vietnam Post and Telecommunications Corporation
(VNPT) has been assigned by the government of
Vietnam to be an investor in this project.
VINASAT Project
• The “VINASAT project ” for launching the
first Vietnamese communication satellite is
initiated in 1995.
• The pre-feasibility study of the VINASAT
project is approved in 1998.
• The National Steering Committee for
VINASAT project headed by one Deputy
Prime Minister has established on May 1999.
VINASAT Project
• The feasibility study of VINASAT is approved
on the end of 2002.
• The international bidding of VINASAT is
carried out in July 2003.
• But the first communication satellite of Viet
Nam VINASAT won’t be launched in 2005 as
planned. The delay comes amid Vietnam ‘s
unfinished negotiations with partner nations
regarding the satellite’s orbit position.
Strategy for Research and
applications of Space Technology
up to 2020
• In June 2002, the Prime Minister asked
VAST in collaboration with MOST and
relevant ministries to elaborate the
strategy.
• After 3 years of discussion and revision,
now the final draft of the strategy has
submitted to the PM for approval in this
quarter of 2005.
Strategy for research and
applications of Space Technology:
main tasks/projects
• VINASAT project (Ministry of Posts and
Telematics).
• Receiving ground station, satellite data
centre (MONRE).
• Small satellite project (VAST).
• Space Technology Institute (VAST).
• Viet Nam Space Commission (VAST).
Strategy for research and
applications of Space Technology:
main tasks/projects
• National Research Programme on
Space Technology (MOST).
• Space Technology specialists training
(Ministry of Training and Education).
“Natural Resources and
Environment Monitoring System”
Project
• MONRE has submitted this project. The technical
system of the project consists of:
– Viet Nam ground station (VNGS);
– National Data Center (NDC);
– Data Utilization Systems (DUS).
• The VNGS uses multi sensor receiving technology of
EADS (European Aeronautic Defense and Space
company).
• The VNGS is located at Tu liem district (Hanoi) and
will be operating from the end of year 2007 under the
management of Remote Sensing Centre (RSC).
Small satellite project
• VAST has submitted to the PM a prefeasibility study of the project in 2001. But,
this project was temporally stop until the
“ Strategy for research and applications of
Space Technology “ will be approved.
• VAST proposes to participate a constellation
of small satellites for monitoring disaster, if
any, in the period (2006-2010).
Establishment the Viet Nam Space
Commission (VNSC)
• VAST’s proposal: to establish Viet Nam Space
Commission with the following tasks:
– To co-ordinate all space activities implementing the
projects or tasks of the Strategies.
– To represent of Viet Nam in participating space activities
and organizations.
• Minister of Science and Technology will be the
President of VNSC. President of VAST will be
standing Deputy President of VNSC. The deputy
ministers of ministries relevant are members of
VNSC.
Establishment the Space
Technology Institute (STI)
• STI will be establish as the 19th national
institute of the Vietnamese Academy of
Science and Technology.
Conclusion
To develop Space Technology, besides the
mobilizing all internal resources, Viet Nam
needs the experiences and technology from
developed countries through bilateral or
multilateral cooperation.
Comment on the main theme of
APRSAF-12
• Under the main theme entitled “ Maximizing
Space Benefits for the Society “ , we agree to
focus on the use of space technology to cope
with environment problems, to prevent and to
mitigate risks of disasters.
• During the recent years, natural disasters
occurred more frequent in the world, particularly
in Asian region, including Viet Nam and caused
serious aftermath. Here, we refer the tropical
storm Damrey which cause a flash flood in Yen
Bai province.

After the flash flood
Tropical Storm Damrey
• 69 people were killed and 28 injured by the storm and
resulting floods and landslide that stuck the northern
mountain provinces.
• 4,746 houses were washed; 113,523 houses were
submerged.
• 77,841 m of sea and river dykes were damaged.
• 318,945 ha of rice and subsidiary food crops were
destroyed.
• Loss are estimated at 3,5 trillion VND.
• The co-operation had helped keep losses to a minimum.
But the forecast flash floods was still inadequate. How
to use space technology efficiently to forecast flash
flood and landslide ?
