Can any space nerds help me understand how the Blue Origin capsule came back down without any re-entry burns? Was this a trajectory thing or some kind of superior material used? Falcon crew capsule for comparison

men need to be working real jobs again. muscle and a shovel style jobs. testosterone levels would rise and men would feel like they had a purpose again. men yearn for the oil rigs and coal mines not the excel spreadsheets and 9-5 grind. we've neutered them, one business day at a

The US Navy has managed a total of 273 nuclear reactors, 6200 reactor-years, over 177 million miles, averaging 4 new reactors per year over 70 years. They have done this with a perfect safety record. Zero accidents. Zero injuries, zero deaths, zero environmental pollution.
