following the satellite’s launch. Sputnik 1 remained in orbit until January 4, 1958, when it burned up on reentering Earth's atmosphere. Ultimately, the launch of the first artificial satellite spurred many countries, including the United States, to pursue space initiatives that continue to ...

On this day 60 years ago, America became the second country to send a human-made object into low-Earth orbit, with the successful launch of its first satellite – Explorer 1. The launch of Explorer 1 took place against the backdrop of the Cold War between the United ...
Sputnik 1.It was an event that galvanized the world and spurred the fledglingU.S. space effortinto high gear. No one who was alive at that time can forget the electricity of the moment when humans first lofted a satellite into orbit. The fact that it was the U.S.S...
It was a good night for the Germans, as well as for the American space program. Explorer 1's science Explorer 1's launch was a large policy coup, to be sure, but what was also interesting was the science the little satellite beamed back. Its prime science experiment was a cosmic ray ...
Besides the events in Wuhan, about 500 activities, such as space open day, popular science lectures, knowledge contests, exchanges and discussions, will be held across the country. Starting in 2016, China chose April 24 as the Space Day of China to mark the launch of its first satellite "...
To the American public, however, the launch ofExplorer Imeant only one thing: America was finally back in the Space Race. But it would be a hard road to the stars, for on May 15, 1958 the Soviets launchedSputnik 3,a massive satellite a thousand times heavier thanExplorer I.This ...
Japan’s LignoSat will test wood’s resilience in space and could lead to a new era of more sustainable, less polluting satellites
In this research, we provide a novel approach to the development of effective numerical algorithms for the solution of first-order IVPs. In particular, we detail the fundamental theory behind the development of the aforementioned approaches and show how it can be applied to the Adams–Bashforth ...
Sullivan's spacewalk occurred just months after the first-ever spacewalk by a woman (cosmonaut Svetlana Savitskaya's excursion in July of that year) during Challenger's nine-day mission to deploy an Earth observation satellite (the Earth Radiation Budget Satellite) and demonstrate satellite refueling...
