The International Space Station (ISS) has completed its 150,000th orbit around Earth, according to a statement from Roscosmos on Tuesday. The milestone, which marks a significant achievement in human spaceflight, comes more than 25 years after the station’s launch into orbit. Roscosmos reported that the anniversary orbit took place between 1:32 PM and 3:05 PM Moscow time, with the station traveling from Sumatra, Indonesia, to the Indian Ocean.
Over its operational lifespan, the ISS has covered approximately 6.4 billion kilometers equivalent to 30 times the average distance from Earth to Mars and nearly reaching Pluto’s orbital path. The ISS was first launched on November 20, 1998, with the deployment of the Zarya functional cargo module. Since then, it has remained a cornerstone of international space collaboration, hosting astronauts from multiple space agencies, including NASA, ESA, JAXA, and CSA. The station orbits Earth at an average altitude of 420 kilometers and completes roughly 16 orbits per day.
Designed as a microgravity research laboratory, the ISS has facilitated numerous scientific breakthroughs in fields such as medicine, materials science, and astrophysics. It continues to serve as a testbed for technologies that may be crucial for future deep-space missions, including potential crewed missions to Mars. Despite its success, the ISS is expected to be decommissioned by the end of the current decade, with discussions underway regarding its successor.
NASA and its international partners have proposed transitioning to commercial space stations and expanding lunar exploration through the Artemis program. The 150,000th orbit underscores the station’s enduring contribution to space exploration and international cooperation, reinforcing its role in advancing humanity’s presence beyond Earth. – By EuroWire News Desk.
