On The Road Again

Heading to Florida in the morning for the mundane, non-landing Falcon 9 launch on Tuesday (though recent wind forecasts make me suspect it will slip to Wednesday), then down to south Florida to deal with another house we want to sell. Then back up to the Cape on Monday for what I hope is a Tuesday Falcon Heavy launch (which will be historic). From there, to DC on Tuesday night. I’ll be checking in from the road, but be good in comments.

The Lancet

It’s catching up on the nutrition science:

High carbohydrate intake was associated with higher risk of total mortality, whereas total fat and individual types of fat were related to lower total mortality. Total fat and types of fat were not associated with cardiovascular disease, myocardial infarction, or cardiovascular disease mortality, whereas saturated fat had an inverse association with stroke. Global dietary guidelines should be reconsidered in light of these findings.

It’s a epidemiological study, but it matches most recent research.

They fired, right at the opening of the window. Probably have Youtube later today.

The fact that it happened right at the beginning of the window is a good sign, indicating that there were no issues with the wet dress rehearsal. I’m curious to know if all twenty-seven engines lit. If they did, they must be very close to being ready for a first flight. Also, they’re past Elon’s initial concern that the pad wouldn’t be able to handle the thrust, or the plume interactions. There should be no proble with lift off, and now probably the biggest uncertainty will be the ability to stage the side cores in flight (and perhaps fly and land three cores simultaneously).

Here’s the view from SpaceX’s camera.

If I fly in on Monday, I might see two launches. There’s a Falcon 9 flight scheduled for Tuesday.
