The article "The challengers" was published in Science, Volume 391, Number 6788, Page 876, February 2026.[4] This is a short paper that deals with challenges in space exploration.[4] In the context of the space shuttle Challenger, its missions from 1983 to 1986 are mentioned, during which it made nine manned flights and completed almost a thousand orbits of the Earth in 62 days in space.[1] Crews launched civilian satellites, repaired a solar telescope, and conducted research into extreme zero-gravity conditions.[1] Among the passengers were the first American woman and the first African American astronaut.[1] Challenger exploded 73 seconds after the start of the last mission.[1] Engineers warned of possible failure, but the pressure to meet the program outweighed safety concerns.[1] The report highlighted a communication gap between engineers and managers who were focused on budget and deadlines.[1]
