Viewing the International Space Station in the sky over Jeddah | Time and method of observation
Engineer Majed Abu Zahra, head of the Jeddah Astronomical Society, announced that the skies over Jeddah will witness a remarkable astronomical event this Sunday evening: a bright and clear transit of the International Space Station. This transit presents an exceptional opportunity for residents and astronomy enthusiasts to see this colossal engineering marvel with the naked eye as it orbits the Earth at tremendous speed, appearing as a brilliant point of light across the sky in a breathtaking spectacle.
Abu Zahra explained that this transit is one of the best monitoring opportunities available during the current period, given the station's great brightness and its long and clear path that will cross the sky from horizon to horizon almost, allowing it to be easily seen even from within residential neighborhoods that suffer from light pollution.
Details of the International Space Station transit
According to precise astronomical calculations, the International Space Station to appear above the northwestern horizon at 7:52:33 PM Saudi time, at an altitude of approximately 10 degrees. The station will appear as a bright white star moving swiftly and steadily across the sky, without flashing, unlike aircraft which are characterized by their intermittent lights. The visible transit will last for 5 minutes and 23 seconds, ample time to enjoy and document the spectacle.
The station will reach its highest point in the sky at 7:55:50 PM, at an altitude of 77 degrees northeast, placing it in an ideal position for astrophotography. During this peak, its apparent magnitude will reach -3.2, making it brighter than Jupiter and the third brightest celestial object after the Moon and Venus. This remarkable brightness is due to the reflection of sunlight off its massive solar panels, which power it.
A giant laboratory and an icon of international cooperation
The International Space Station (ISS) is more than just a fleeting bright spot; it is the largest human-made structure ever built in space and a powerful symbol of international scientific collaboration. This monumental project, which began assembly in orbit in 1998, is the result of a partnership between five global space agencies: NASA, Roscosmos, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), and the Canadian Space Agency (CSA). Orbiting at an altitude of approximately 400 kilometers above Earth, the station completes a full orbit around our planet roughly every 90 minutes, traveling at speeds of up to 28,000 kilometers per hour, allowing astronauts aboard to witness 16 sunrises and sunsets every day.
Scientific importance and inspiration for generations
The station's greatest importance lies in its role as a unique scientific laboratory for conducting advanced research and experiments in a microgravity environment, something impossible to replicate on Earth. This research encompasses diverse fields such as biology, physics, astronomy, and earth sciences, and its findings contribute to the development of new technologies that benefit humanity, as well as paving the way for future long-term space missions, such as Mars exploration. Furthermore, witnessing the station's transit serves as an inspiration to young people and future generations, encouraging their interest in science, technology, engineering, and mathematics (STEM). This aligns with global and local trends, such as Saudi Vision 2030, which places great emphasis on the space sector, as recently demonstrated by the dispatch of Saudi astronauts to the International Space Station.
The transit will end with the station gradually disappearing as it enters the Earth's shadow cone at 7:57:56 PM near the southeastern horizon, where the solar panels will stop reflecting sunlight, appearing to vanish into the sky.
