Ariane 6 And Vulcan Rockets Mark Major Milestones

Recent launches by Arianespace and ULA highlight global advancements in rocketry, while China expands its satellite network and the U.S. Space Force debuts new tracking technology.

It’s been a landmark week for space launches and technology, with major milestones achieved by rocket builders on both sides of the Atlantic and Pacific. As the world’s attention focused on the skies, storied names like Arianespace and United Launch Alliance (ULA) marked critical advances, while China’s private sector demonstrated its growing prowess in satellite deployment. Throw in new radar technology, plans for a lunar nuclear reactor, and the ever-present dance of space weather, and you’ve got a week that encapsulates the current dynamism—and complexity—of the space industry.

On August 12, 2025, Arianespace’s Ariane 6 rocket soared from French Guiana, completing its third flight and carrying a European weather satellite into orbit. According to Ars Technica, this milestone came just 13 months after the rocket’s inaugural launch, a pace that underscores Europe’s determination to maintain independent access to space. Not to be outdone, less than 20 minutes later, ULA’s Vulcan rocket thundered off from Cape Canaveral, Florida, embarking on its own third mission—dubbed USSF-106—on behalf of the U.S. Space Force. The Vulcan, which took more than 19 months to reach its third flight, was tasked with a crucial national security mission, highlighting the strategic role of advanced launch vehicles in safeguarding U.S. interests above the atmosphere.

These achievements are even more notable when placed within the broader context of Western rocketry. As Ars Technica points out, Ariane 6 and Vulcan are two of only three major new rockets from the Western world to have made their orbital debuts in the past two years—the third being Blue Origin’s New Glenn, which has so far flown just once. Meanwhile, SpaceX’s much-hyped Super Heavy/Starship system, though it has completed nine flights, has yet to reach orbit. This competitive landscape reflects both the technical challenges and the high stakes of modern launch development.

But the week’s rocket activity wasn’t limited to the United States and Europe. On August 8, China’s private satellite operator Geespace successfully launched 11 satellites aboard a Jielong 3 (Smart Dragon 3) rocket. As reported by Space News, the mission lifted off from an ocean platform in the Yellow Sea, off the coast of Rizhao in Shandong province. This marked the sixth flight for the Jielong 3, which is developed by a commercially oriented spinoff of the state-owned China Academy of Launch Vehicle Technology. Geespace’s new satellites are designed to expand low-power Internet of Things connectivity in emerging markets—a clear sign of China’s ambitions to carve out a leadership role in commercial space applications.

The Jielong 3 launch had an unexpected coda: the rocket’s fourth stage, left in orbit after deploying its payload, reentered Earth’s atmosphere late on August 10. Residents in Spain were treated to a dramatic fireball streaking across the night sky, initially mistaking it for a meteor from the Perseid shower. As El Mundo clarified, the spectacle was in fact the fiery demise of the Chinese rocket stage, with any surviving debris likely plunging into the Mediterranean Sea. Incidents like this are a reminder of the persistent challenge of orbital debris and the need for robust tracking and mitigation strategies.

That’s where the U.S. Space Force’s latest technological leap comes into play. According to SpaceWar, the Space Force has successfully tested a new deep space radar, capable of tracking multiple satellites from a staggering 22,000 miles above Earth. This system is designed to enhance space situational awareness—a critical capability as the number of satellites and pieces of debris in orbit continues to climb. The radar’s ability to detect and monitor even small objects is seen as a major step forward in protecting operational satellites from potential collisions, and in maintaining the safety and effectiveness of space-based infrastructure.

The Space Force is also undergoing organizational changes. As reported by SpaceNews, it will integrate space missions previously conducted by the Air Guard, a move intended to streamline military space operations and avoid the creation of a separate Space National Guard. Air Force Secretary Troy Meink endorsed the shift, citing the benefits of unified command and operational efficiency. For those watching the evolution of military space policy, this consolidation signals a more agile and coordinated approach to the defense of U.S. interests in orbit.

Meanwhile, innovation isn’t limited to the stars themselves. The U.S. Army is exploring the use of 3D printing technology to revolutionize logistics, with the goal of manufacturing drone components and vehicle parts on demand—even in austere environments. Breaking Defense notes that this approach could eventually extend to satellite manufacturing, allowing for rapid production and deployment of cubesats or other components directly in the field or even in space habitats. Such advances could dramatically alter the cost, speed, and flexibility of space missions, not just for the military but for the entire industry.

On the scientific frontier, NASA has set its sights on building a nuclear reactor on the Moon by 2030. Acting Administrator Sean Duffy described this as a necessary step for establishing sustainable lunar bases, as reported by Space.com. The proposal has sparked debate over the legal and regulatory frameworks that would govern such an installation, raising questions about international treaties, lunar governance, and the environmental impact of nuclear technology beyond Earth. While still in the planning stages, the project could pave the way for a new era of lunar exploration and resource utilization.

Amidst all this activity, the space environment itself has remained relatively calm. As of August 15, reports from Space.com indicate that space weather conditions are quiet, with no significant solar storms forecasted. However, high levels of energetic electron flux in geosynchronous orbit have triggered alerts, and minor to moderate radio blackouts are possible between August 15-17. Geomagnetic activity is expected to reach active levels on August 11, with minor storming likely on August 18-20 and again on August 28. For satellite operators, these forecasts are more than academic—they can influence everything from communication reliability to the safety of onboard electronics.

Looking ahead, the launch calendar remains packed. China, Russia, and the United States all have missions scheduled in the coming days, including several SpaceX Falcon 9 flights carrying Starlink satellites, the next Bion-M biological research satellite from Russia, and the tenth test flight of SpaceX’s Starship from Texas. Each mission adds to the growing tapestry of activity in low Earth orbit and beyond.

In this ever-evolving landscape, even the satellites themselves are getting smarter. Take YUNHAI-1 03, a Chinese meteorology and earth observation satellite launched in 2022. As highlighted by Space.com, it features two deployable solar arrays, allowing it to efficiently harness solar power while conducting vital observations. It’s a small example, but emblematic of the technical ingenuity driving the new space age.

From fiery reentries over Europe to the quiet hum of deep space radars, this week has offered a vivid snapshot of a sector in motion—one where scientific ambition, national security, and commercial opportunity are increasingly intertwined.
