What are the disadvantages of sputnik-1?

Sputnik 1, while a groundbreaking achievement in space exploration, had several disadvantages. Its design was limited by the technology of the time, resulting in a relatively short operational lifespan of about three months before its batteries died. Additionally, it provided minimal scientific data beyond basic telemetry and atmospheric conditions, which restricted its utility for further research. Finally, the geopolitical implications of its launch heightened Cold War tensions, contributing to a competitive arms race rather than fostering international collaboration in space.
