a power source that isn't crappy. That would enable exoskeletons and robots that are useful.
If you watch the demo videos, they all either have a power cord dangling off the exoskeleton/robot (presumably plugged into A/C mains) or an annoyingly loud and smoky 2-stroke generator running onboard. That's because current batteries provide nowhere near enough juice to power these suits/robots to any degree of usefulness.
We aren't lacking in servo/microcontroller/robotics tech, we're lacking a decent battery tech.
The thing is, it's not really sarcasm. Pretending to be stupid and confused while not making a point doesn't serve any purpose other than maybe as a troll.
Your attempt to confuse here isn't really helpful.
Google does *sell* Google Glass and Nexus phones and tablets and Chromecast and Nest and soon Dropcams and probably more. They are "Google products" branded and sold by Google as theirs.
Mozilla only has one device that it works on directly, the Firefox OS Flame reference phone. The rest of the hardware you see out there is being made and sold by someone else.
And that's not just true of the hardware. Much of the work going on to extend Firefox OS software into areas outside of phones is being done by third parties for their products.
Mozilla doesn't build hardware. We make software, including Firefox OS. Firefox OS is a completely open platform freely available for any company to build on top of without restriction. There are dozens of companies building Firefox OS-based products today and there will be more tomorrow, covering mobile phones, tablets, TVs, set top boxes, game consoles, streaming dongles, wearables, and more. Some of those companies are working directly with Mozilla and others are taking the code and running with it on their own.
Gee, I guess the engineers at NASA don't know about radiation levels at Jupiter. Lucky for them you posted about it on the internets. I'll forward them your post so they aren't left in the dark.
little engineering justification, sure. But there's a whole lot of financial justification.
It's all about operational costs. To retrieve something like an Apollo capsule that pops a parachute and lands in the ocean, they have to deploy fleet of ships and bunch of personnel, which all costs money even though it has nothing to do with rocket engineering. Also landing in salt water will mean extensive refurbishing and/or making the rocket marine-resistant, which leads to even more downtime and money.
Like in the airliner business, time is money. The faster you can relaunch, more money you save. Elon's goal is to have both stages land in the same place they launched from, clean em up a bit, refuel, and relaunch in a matter of days (or hours). Like an airliner.
Huh? No the first stage never makes it into orbit. Otherwise you wouldn't need a second stage and it would be a SSTO vehicle.

But I'm not religious about it.
