Nuriho Tan SK Hynix Semiconductor begins verification of performance in space

Nara Space Space Verification Satellite Unit 2 succeeds in first two-way communication

Space environment testing of domestic devices and components such as DRAM and NAND flash

(Seoul = Yonhap News) Reporter Cho Seung-han = Nara Space Technology, a microsatellite company, announced on the 8th that the space verification satellite 'E3T Unit 2', which is responsible for developing and operating the platform main body, succeeded in two-way communication with the ground station after the 5th launch of Nuri.

E3T Unit 2 was loaded onto the 5th launch of the Korean Launch Vehicle Nuri at Naro Space Center in Goheung, Gwangju, Jeollanam-do at 12:25 p.m. on the 7th, and was separated from orbit about 17 minutes after launch.

In the first communication, which took place about 1 hour and 57 minutes after separation, two-way communication was successfully established with the satellite control center at Nara Space's headquarters.

Nara Space announced that it is checking the basic condition of the satellite and proceeding with initial operating procedures.

E3T Unit 2 was developed to verify domestically developed space semiconductors, electronic devices, components, and technologies in an actual space environment.

E3T Unit 2, manufactured with 12 units (U, 1U is 10 cm in width, height, and height) and weighs 18.08 kg, consists of a 4U main body system and an 8U payload space.

It is designed to accommodate a variety of payloads with different characteristics to test and collect and transmit data in a space environment.

SK Hynix's DRAM and NAND flash, Insera Solutions' high-speed precision adjustment mirror, Momentum Space's reaction wheel, Korea Advanced Institute of Science and Technology (KAIST)'s attitude determination and system module, Cosmobee's 1A class hollow cathode for electric thruster, and Intergravity Technologies' orbital transport avionics equipment are verified in the actual space environment.

Nara Space also loaded E3T Unit 1 on the fourth launch of Nuri in November last year, and E3T Unit 1 has been in operation for 11 months.

Park Jae-pil, CEO of Nara Space, said, "It is significant that we have successfully secured the operational basis for E3T Unit 2 following the E3T Unit 1 launched last year, and have once again confirmed a stable satellite platform that can verify space elements and components in the actual space environment." He added, "We will continue to expand verification opportunities for various space elements and components in line with the global New Space trend and continue to accumulate related capabilities to serve as a foundation for the growth of the domestic space element and component industry. “I’m going out,” he said.
