Wearable Tech

22 Comments

Forget it, what people want is more battery life.

This obsession with “thin” phones makes me crazy. Have the gay men who run the fashion industry, but hate normal female bodies, taken over tech as well?

I just “upgraded” from my dying Droid Global 2, a phone whose batteries were easily changed, for a Droid 4, which has a better OS, and is 4G instead of 3G, and slightly thinner, but has a non-replaceable battery. I consider it a downgrade.

Successful Flyback

30 Comments

…and failed landing. That’s what flight test is about. They’ll learn from it, as they always do from a failed attempt.

I would note, though, that this does complicate their operations, if they plan to land down range every time, and can’t return to launch site. I suspect they’ll determine that the problem was crappy weather conditions, and their FLIR or whatever they were using for guidance wasn’t doing very well. That means that there’s a new condition imposed on a decision to fly — weather at recovery site. Shuttle often scrubbed with good weather at the Cape, due to unacceptable conditions at abort sites, and that was just for contingency. If SpaceX wants to recover down range, they may occasionally have to make a decision as to whether to risk the loss of a stage, or delay and arouse customer ire. It will depend on whether or not there’s a tight window (e.g., a planetary mission), and who the customer is.

Oh, I hadn’t read to the end. It sounds like it wasn’t a weather problem — they “ran out of hydraulic fluid” (not sure what that means — it’s not a closed system?). But that seems like good news, both for their chances of recovering next time, and for being able to operate in less-than-perfect conditions. Sounds like they only thing that might prevent a launch, in terms of barge conditions, would be sea state (or high winds), not weather per se.

Here‘s what looks like a reasonable explanation from Jon Goff. I haven’t read the post itself yet, but I’m sure it’s worthwhile to do so.

OK, Elon just tweeted that it was hydraulics for the control fins, and they came within 10%. So that means an excellent chance of success the next time, with the addition of a little bit more juice.
