In Which I Disagree With @Instapundit

I agree that neurosuspension is better than nothing, but I disagree that whole body is for suckers. This is a topic that’s been going on for years in cryonics discussions.

We simply don’t know how much of our identity is in our body, as opposed to simply our brains. For instance, I suspect that there is a lot of distributed motor intelligence in athletes and musicians — when I play an instrument (or for that matter, simply type on a keyboard) I have a sense that my hands aren’t being directly controlled by the brain, but are rather receiving higher-level commands issued by the brain that are implemented at a lower level, based on local memory. I don’t know that to be the case, but if you can afford to keep the whole body, it might end up being worth not having to reacquire old skills.

The Coalition For Big Expensive Rockets

I agree with Stephen Fleming about this press release.

I’ve been pointing out all of the nonsensical, engineering-illiterate praise for SLS on Twitter. “Most powerful,” “fastest” etc. I loved this one today:

My response:

The SpaceX Vehicle Loss

Apparently it was a blocked sensor port:

“I can tell you that it certainly looks like it was basically a single-point failure that existed on that test article that does not exist on the Falcon 9,” Reisman said. “We think it was a failure of a single sensor, and Falcon 9 has multiple sensors in its algorithm that it uses. So if the same failure occurred on the Falcon 9 it would not affect the mission in any way.”

The sensor failure in one of the three Merlin 1D engines on the Falcon 9R caused the vehicle to stray from its intended flight path, triggering an automatic self-destruct command to ensure it did not threaten nearby people and property.

Reisman said an operational Falcon 9 flight, which uses nine first stage engines, could overcome the loss of an engine. On the three-engine Falcon 9R, such redundancy does not exist.

But still no announcement of a new launch date for AsiaSat 6?
