SEOUL (Reuters) — South Korea’s military said it had successfully test-fired a solid-fuel space rocket for the first time on March 30, a step it says will help eventually launch a constellation of satellites to better monitor threats such as North Korea.
The launch is the first such test since South Korea and the United States agreed last year to end decades of restrictions on the South’s ballistic missile and rocket development, and comes less than a week after North Korea conducted its highest missile test yet at that time.
“The success of the test launch of this solid-propelled space launch vehicle is an important milestone in strengthening the defense power of our military’s independent space-based surveillance and reconnaissance field at a very critical time,” the Ministry of National Defense said in a statement, citing the recent test of an intercontinental ballistic missile (ICBM) by North Korea.
The defense minister observed the launch of the rocket, which was developed with “pure Korean technology,” the statement said.
In October, South Korea conducted the first test launch of the Nuri liquid-fueled rocket, its first domestically built space launch vehicle. Nuri blasted off but failed to fully place a dummy satellite into orbit, delivering mixed results for a test launch that represented a major leap for the country’s ambitious space plans.
In contrast to the Nuri’s liquid-fuel design, a solid-fuel rocket such as the one tested on March 30 would be simpler, less expensive to develop and manufacture, and faster to launch, the defense ministry said.
The March 30 test verified the large solid-fuel engine, fairing separation, stage separation, and upper-stage attitude control technology, which are essential technologies for space launch vehicles, the statement added.
