Successfully launched Vietnam’s NanoDragon satellite

On the morning of 9/11, Vietnam’s NanoDragon satellite flew into space at the Uchinoura launch site, Kagoshima Prefecture, Japan, starting a space mission.

A Vietnamese satellite was launched at the Uchinoura Space Center launch site, Kagoshima Prefecture (Japan). Around 9:06’54” (Hanoi time), NanoDragon satellite ”Made in Vietnam” was successfully separated from Japan’s Epsilon No. 5 rocket, entered orbit, and started working in space. As expected, around 9:30 a.m., NanoDragon approached the sky of Vietnam. The satellite is designed with the task of tracking and monitoring vehicles at sea, expected to operate in a solar synchronous orbit at an altitude of about 560 km.

Launched with NanoDragon, there are 8 other Japanese satellites in the program “Innovative Satellite Technology Demonstration-2”.

Among these are:

– A small satellite: RAISE-2 (110kg) of the Japan Aerospace Agency; 4 micro-class satellites: HIBARI (55 kg), Z-Sat (46 kg), DRUMS (62 kg), TeikyoSat-4 (52 kg).

– Four cubesat-class satellites: NanoDragon (3.8 kg) of Vietnam, ASTERISC (4kg) of Chiba Institute of Technology, ARICA (1kg) of Aoyama Gakuin University, KOSEN-1 (3kg) of National College Kochi family.

According to the original plan, the launch time was 9:48’21” (7h48’21” Hanoi time), however, it was later adjusted to 9h55’16”, to match the orbits of the spacecraft. other satellite equipment in the space environment.

At the scheduled time, the Epsilon 5 rocket was on fire, leaving the launch pad, sending 9 satellites into space in the correct orbit relative to the control room. One minute after the rocket successfully launched, the 1st and 2nd stage engines were disassembled, respectively. Three minutes after launch, the propulsion was operating normally.

According to the schedule, after about 52 minutes, the rocket began to drop the satellites it was carrying into orbit. The first satellite to be released was RAISE-2. NanoDragon satellite was released into space for the last time, after leaving the ground 1 hour 11 minutes 38 seconds.

Share with VnExpress From the Uchinoura launch site, Mr. Vu Hong Nam, Vietnamese Ambassador to Japan, said he was emotional when he witnessed with his own eyes the moment the Epsilon No. 5 rocket from the Uchinoura launch station started to launch, carrying the NanoDragon satellite launched by the US agencies. Scientists and experts from Vietnam Space Center (VNSC) develop and fly into outer space.

“This sacred moment marks once again the two Vietnamese words engraved on the maps of countries on the way to conquering space,” he said. It is really a feeling of pride mixed with pride when witnessing the achievements of Vietnam’s space industry. According to the ambassador, this is a very proud initial achievement of the Vietnam Space Center under the Vietnam Academy of Science and Technology, marking an important step forward for Vietnam’s space industry.

At the Vietnamese bridgehead, Assoc. Prof. Dr. Pham Anh Tuan, General Director of Vietnam Space Center (VNSC) said that Vietnam has manufactured 3 types of satellites: PicoDragon (under 1kg), NanoDragon (under 10kg). and MicroDragon (under 100kg). With the PicoDragon satellite, just fly up and broadcast a signal confirming that the satellite is working. The MicroDragon satellite has two missions: testing the technology and training the team to master satellite technology. The NanoDragon satellite has two tasks: a signal generator to automatically identify ships and adjust the position of the satellite in orbit.

NanoDragon is designed to operate for at least 6 months in orbit, but according to calculations by Vietnam National Space Center, the satellite can operate for up to 2 years.

The construction project of the Vietnam Space Center in Hoa Lac Hi-Tech Park will be completed in 2023. “When the technical infrastructure here is completed, Vietnam will make a larger satellite. There will be an installation center. assemble and test satellites up to 200 kg. With small satellites like NanoDragon, it will not have to be brought to Japan for testing like today, but can be done in the country,” Mr. Tuan said. VnExpress.

Assoc. Prof. Dr. Pham Anh Tuan said that in Vietnam’s Science and Technology strategy to 2030, the National Satellite Center will carry out the task of building a national Earth observation system using small satellites. The construction and design of this satellite beam will be performed by a team of Vietnamese engineers.

NanoDragon is a nano-class cubesat satellite, with the size of 3U (100x100x340.5mm), developed by VNSC engineers of the Vietnam Academy of Science and Technology.

The process of researching, designing, integrating and testing satellite functions is completely done in Vietnam, by VNSC’s research staff. The entire mechanical structure and power distribution circuit and some other auxiliary circuits of the satellite are also manufactured in Vietnam.

This satellite was sent to Japan, handed over on August 17 to move to the Uchinoura Space Center launch site, Kagoshima Prefecture, to check the final stages before entering the launch pad.
