5️⃣ Frequently Asked Questions (FAQ)

Q: How does SpaceX reuse rockets?

A: After launch, lands and recovers the first stage, then refurbishes it for the next launch.

• SpaceX's reusable rocket process is as follows: First, launches rocket to put satellite or cargo into orbit. Second, as the first stage rocket that completed its mission returns to Earth, fires retro rockets to reduce speed. Third, lands vertically on ground landing pad or sea-based drone ship platform. Fourth, brings recovered rocket to factory to inspect engine and structure and repair necessary parts. Fifth, places refurbished rocket back on launch pad for next launch. SpaceX has succeeded in reusing a single rocket over 10 times, reducing launch costs by over 80% compared to before.
• The core of reusable technology is precise landing control. As the rocket falls at thousands of kilometers per hour, reduces speed with retro rockets, and computer calculates wind and center of gravity to control landing exactly at landing point. This technology was perfected after years of failures and tests, and now successfully recovers rockets in almost all launches. Korea must also develop this technology to compete in the commercial launch market.

Q: What does Korea need to become like SpaceX?

A: Need to secure reusable rocket technology, expand private investment, and develop commercial market entry strategy.

• For Korea to become a space powerhouse like SpaceX, must solve several challenges. First, must secure reusable rocket technology. Nuri-ho is disposable so launch costs are high, lacking commercial competitiveness. Goal is to secure reusable technology by the 2030s through next-generation rocket development, but technology difficulty is high and requires massive investment. Second, must strengthen role of private companies. Hanwha Aerospace leading Nuri-ho launch is a good start, but more private companies must invest and compete in space industry for innovation to occur. Third, must enter commercial launch service market. Global small launch vehicle market size exceeds 2 trillion won, must gain competitiveness in this market to generate profit.
• Government support is also important. Must ease regulations and create environment where private companies can freely conduct space activities. Must secure sufficient R&D budget and need culture that tolerates failure. SpaceX also improved technology through repeated failures over years. Korea also needs attitude of continuously investing and challenging from long-term perspective. Talent cultivation cannot be left out, must train many space engineering experts to have technological competitiveness.

Q: Is satellite internet like Starlink needed in Korea too?

A: Useful for resolving communication gaps in mountainous and island areas and for disaster communications, but in competitive relationship with existing infrastructure.

• Korea has well-established ground communication infrastructure, but satellite internet is also needed in some areas. First, mountainous areas and islands are difficult to install ground base stations, so communication speed is slow or connection is unstable. With satellite internet, can use high-speed internet even in these areas. Second, when ground communication networks are cut in disaster situations, satellite internet becomes emergency communication means. Even if base stations are destroyed by earthquakes, floods, or wildfires, satellite signals are maintained, helping rescue and support activities. Third, satellite internet is useful when uninterrupted internet is needed while moving in ships, aircraft, and vehicles.
• However, Korea already has 5G networks nationwide, so need for satellite internet is lower than other countries. Existing carriers are also concerned that satellite internet will encroach on their markets. Also, satellite internet costs more than ground communication and can be affected by weather. Nevertheless, Korea is considering securing satellite internet technology to enter overseas markets or use for special purposes (military, disaster, remote area communication). As global competition intensifies, technology development and strategic response are needed.
