United States President Donald Trump has unveiled new details about a groundbreaking missile defense initiative known as the “Golden Dome”, which he claims will be the first weapon the US places in space. Estimated to cost around $175 billion, the space-based defense shield is expected to become operational within three years, by the end of Trump’s current term. President Trump stated that the system’s architecture has been finalized, building on the announcement he made shortly after returning to the White House in January. At that time, he described the project as a countermeasure against next-generation aerial threats, including ballistic missiles, cruise missiles, hypersonic weapons, and drones, whether conventional or nuclear. Describing it as “very important for the success and even survival of the United States,” Trump emphasized that the Golden Dome will integrate land-, sea-, and space-based technologies. It will feature space-based sensors and interceptors that can track and neutralize threats at various stages of flight—including pre-launch, mid-air, and even space-based missile attacks. Speaking alongside Trump, Pentagon chief Pete Hegseth noted that the Golden Dome will be interconnected with current ground-based defense systems and will serve as a comprehensive shield for the homeland. The system is designed to detect and neutralize a wide array of modern threats, ensuring multi-layered protection. Although President Trump pegged the total cost at $175 billion, the Congressional Budget Office has estimated the full lifecycle cost could exceed $500 billion over two decades. An initial $25 billion in funding has already been announced, and future costs will be gradually absorbed. The initiative will be led by US Space Force General Michael Guetlein, a four-star general with over 30 years of experience in missile defense and space systems. General Guetlein has been part of the Space Force since 2021 and is considered a top expert in aerospace military defense. While primarily intended to defend the United States, Trump revealed that Canada has expressed interest in joining the program, citing the importance of shared North American defense. The Golden Dome marks a major shift in US defense policy, signaling a bold step into space-based warfare and deterrence.

A historic relic of the Soviet Union’s ambitious Venera program met its final fate on May 10, 2025, as the Kosmos 482 Venus lander reentered Earth’s atmosphere after 53 years in orbit. The spacecraft, which had been stranded in an elliptical Earth orbit since its failed launch to Venus in 1972, made its fiery descent at 2:24 a.m. ET (0624 GMT/9:24 a.m. Moscow time) and splashed down in the Indian Ocean, west of Jakarta, according to Roscosmos. A Glitch That Froze a Dream Originally designed as part of the USSR’s Venera series to explore Venus, Kosmos 482 encountered a malfunction during launch due to a timer error, causing an early engine shutdown. This error prevented the craft from escaping Earth’s gravity and left it trapped in a decaying orbit—where it remained for over five decades. A Long Goodbye In the final days before its reentry, the spacecraft completed one last pass over Earth. Italian astronomer Gianluca Masi captured its fleeting silhouette on May 10, showing the vessel as a dashed line against the stars near Rome, thanks to a long-exposure image. Meanwhile, Dutch satellite observer Ralf Vandebergh reportedly captured images that may show the parachute intended for its Venus descent, possibly deployed during reentry—though whether it functioned remains unknown. Disputed Splashdown and Global Tracking Efforts While Roscosmos placed the impact zone in the Indian Ocean, other international trackers gave varying predictions, ranging from the South Asian mainland to the Pacific Ocean. This wide range reflects the complexity and uncertainty involved in tracking aging space debris, particularly one built to withstand the harsh Venusian environment. A Reminder of the Space Junk Crisis Weighing about 495 kg (1,190 lbs) and roughly 1 meter (3.3 feet) in diameter, Kosmos 482’s descent at ~240 km/h (150 mph) carried the destructive potential of a small meteorite. However, its splashdown in the ocean likely prevented any damage on land. Its survival through atmospheric reentry is attributed to its robust design, meant to endure Venus’s high-pressure, corrosive atmosphere. The incident underscores the growing danger of space debris. With more than 14,000 satellites currently orbiting Earth—7,200 from Starlink alone—the risk of collision, uncontrolled reentry, and atmospheric clutter is mounting. On average, three major debris objects enter Earth’s atmosphere daily, a number expected to rise. Kosmos 482’s demise is not only a spectacle of history and engineering but also a warning for the future of orbital sustainability. As Earth’s low orbit becomes increasingly crowded, the legacy of stranded missions like this must shape how humanity plans for the long-term stewardship of space.
