The Arecibo Planetary Radar transmits up to 1 MW (60 dBW) of power with an antenna gain of about 73.3 dB at 12.6 cm wavelength, resulting in an EIRP of roughly 133 dBW (20 TW).

20 TW (Terrawatts) = 20,000,000,000,000 Watts!

Much of it scattered by our atmosphere!

From Wikipedia:

After suffering from myelodysplasia, and receiving three bone marrow transplants, Sagan died of pneumonia at the age of 62 at the Fred Hutchinson Cancer Research Center in Seattle, Washington, on December 20, 1996.^[97] He was buried at Lakeview Cemetery in Ithaca, New York.^[98]

Influencing Factors

• There is a slightly higher incidence of myelodysplasia in males than in females.
• Genetic and environmental factors have been implicated in the etiology of MDS. Exposure to excessive radiation, some toxic chemicals, certain medicines, and viral infections may cause MDS in some people.
