9AM, 16/11, a big flash flood rush to VN middle provinces made 29 people died

Vietnam organizes the Committee for looking for and rescue people who are suffered by Typhoons (fishery boats) incl. MARD,

border army, leaded by 01 Vice-PM

On 8/11/2013, the ship with 600 containers Heung A Dragon (Korea) is swallowed at VN sea

Radar satellite projects(in accompanied with VSC project)

• Finance source: Japan ODA• JV-LOTUSat-1: Vietnam-Japan joint-development of a

radar satellite (assembly in Japan), launched in 2017• JV-LOTUSat-2 : development of

2nd satellite, in parallel with infrastructure establishment for assembly and test in Hoa Lac, launched in 2020

• Training for satellite assembly, integration and testing will be performed in Hoa Lac after the infrastructure is completed.

• Instrument: X-band SAR• Ground sampling distance: ~1m• Total weight: <500kg• Life-time: 5 years• Dimensions: 2.6m x 3.5m x 3m

Development of the Program for classification of the RS objectives of Hanoi in 1995-2010 (Potential of VNREDSat-1 appliations)

• Establish the land use map of Hanoi based on SPOT image (~VNREDSat-1)
