Particularly, in this ‘Untact’ era, radio wave is establishing itself as the key player of the communications.
Radio wave is playing a critical role in the era of the Fourth Industrial Revolution, which the convergence of the ICT technology and other industries has been accelerating. The rocket, named Naro, reached the desired altitude during its first test in 2009 but failed to eject a satellite into orbit, and then exploded shortly after takeoff during its second test in 2010.The radio broadcast industry has been remarkably growing for years. That launch came after years of delays and consecutive failures. South Korea had previously launched a space launch vehicle from the Naro spaceport in 2013, which was a two-stage rocket built mainly with Russian technology. Scientists and engineers at KARI plan to test Nuri several more times, including conducting another launch with a dummy device in May 2022, before trying with a real satellite. The three-stage rocket is powered by five 75-ton class rocket engines placed in its first and second stages. Nuri is the country's first space launch vehicle built entirely with domestic technology. The country is also hoping to send a probe to the moon by 2030. Officials say such an ability would be crucial for the country's space ambitions, which include plans for sending more advanced communications satellites and acquiring its own military intelligence satellites. The smallest third stage carries the payload and is designed to place it into orbit.Īfter relying on other countries to launch its satellites since the early 1990s, South Korea is now trying to become the 10th nation to send a satellite into space with its own technology. Nuri's largest first stage, the core booster stage, was expected to land in waters southwest of Japan after separation, and its second stage was expected to fall in remote Pacific waters east of the Philippines, about 1,740 miles away from the launch site. Officials at the Korea Aerospace Research Institute, the country's space agency, said it would take about 30 minutes to determine whether the rocket successfully delivered the payload into orbit. There had also been concerns that strong winds and other conditions would pose challenges for a successful launch. The launch, which was observed by South Korean President Moon Jae-in, was delayed by an hour because engineers needed more time to examine the rocket's valves. Live footage showed the 154 foot rocket soaring into the air with bright yellow flames shooting out of its engines following blastoff at Naro Space Center, the country's lone spaceport, on a small island off its southern coast. It wasn't immediately clear whether the three-stage Nuri rocket succeeded in delivering a dummy payload – a 1.5-ton block of stainless steel and aluminum – into orbit 372 to 497 miles above Earth. SEOUL, South Korea - South Korea test launched its first domestically produced space rocket on Thursday in what officials describe as an important step in the country's pursuit of a satellite launch program. Officials described it as an important step in the country's pursuit of a satellite launch program. The Nuri rocket, South Korea's first domestically produced space rocket, lifts off from a launch pad at the Naro Space Center in Goheung.
