How Apollo Killed the Rotating Space Station

2025-07-03

This article explores NASA's decision in the 1960s to abandon the development of rotating space stations capable of providing artificial gravity, and the profound impact this decision had on human space exploration. While early designs were viable, the prioritization of the Apollo moon landing program led to funding cuts for artificial gravity research, resulting in humans remaining confined to zero-gravity stations for decades, leading to astronaut health problems like muscle atrophy and bone loss. Today, commercial space companies are revisiting artificial gravity stations, hoping to correct this historical detour and propel humanity towards becoming a spacefaring civilization.

Space Data Centers: The Dream of a Single Launch vs. Harsh Reality

2025-06-27

Starcloud claims a single 100-ton Starship launch could build a 40 MW space data center (SDC) for $8.2M. This analysis reveals this is infeasible, requiring up to 22 launches. Solar arrays need 4 launches, thermal management 13, and server racks 5. Starcloud drastically underestimates launch costs, rendering their economic comparison to terrestrial data centers unrealistic. This highlights the immense engineering challenges and high costs of space data centers, urging a more realistic techno-economic analysis.
