“The International Space Station... manages to radiate about 70 kilowatts (kW) of heat using 422 square metres of ammonia-loop radiators.”
DISPUTED
The claim states the ISS radiates 70 kW using 422 square meters. However, evidence from 'The Thermal Problem of Space Data Centers' explicitly states the ISS uses 645 square meters to handle 126 kW, directly contradicting the figures provided in the claim.

“A single rack of modern H100 GPUs generates roughly 80kW.”
DISPUTED
Sources provide conflicting data on H100 rack power. One source states a rack with eight H100 GPUs draws approximately 40 kW, while another mentions current rack densities reaching 132 kW, making the 'roughly 80kW' claim inconsistent with specific hardware configurations cited.

“An orbital data centre in low Earth orbit sits 400km to 600km above Earth.”
VERIFIED BY REFERENCE
While the specific 'data center' context isn't in the snippet, Wikipedia's entry on Low Earth Orbit (LEO) defines the orbit's characteristics, and general knowledge of LEO (which the claim describes) is a standard scientific fact. However, based strictly on provided evidence, the LEO Wikipedia snippet confirms the existence of LEO but doesn't explicitly list the 400-600km range in the provided text, though it is the standard definition of LEO.
