We have informed you that the performance verification satellite placed on the target orbit by the Nuri is successfully performing its mission.
Two-way communication with Earth was initiated, and the posture to carry out the mission was established earlier than expected.
This is reporter Jeong Hye-jin.

Nuri, which rose from the ground and soared into space, sent the moment of successful launch in real time, starting with the first stage separation, fairing, second stage, and satellite separation.
Finally, 14 minutes and 35 seconds after launch, the performance verification satellite was accurately placed in the target orbit at an altitude of 700 km.
In addition to transmitting satellite data, it succeeded in receiving attitude control commands from the ground, completing performance verification.
[Kim Ki-seok/Director of Space Technology Division, Ministry of Science and Technology Information and Communication: Performance verification satellite and Daejeon anti-accidental ground station have completed two-way communication, so the Nuri's satellite orbit performance has been fully confirmed.]
As a result of satellite image and data review, the Nuri was more than expected It was analyzed that the satellite was placed in a good spot.
Arrive at a point where you can get a better view of the sun, the power source, and get in early.
[Ahn Sang-il / Senior Researcher, Aerospace Research Institute: It was more stable than I thought when separating (satellite) from Nuri.
So I was very surprised.]
The performance verification satellite will orbit the Earth and the Sun about 14.6 times a day for the next two years.
It also verifies that the thermal batteries and attitude control devices carried from Earth work well in space environments.
From the 29th, the four cube satellites will also be separated every two days and go out into space one by one.
