Comment Does Hubble need 'embedded' or "real time' (Score 1) 106

It uses VRTX, reportedly. Linux wasn't suitable as a real-time OS when the Hubble was designed, or really even when the Hubble got the 486 installed in 2009.

Why was VRTX chosen? Because of the embedded environment or because of real time needs?

If the decision was about embedded and real-time was not required, then Linux would be a viable solution today. Today, embedded Linux is a fine choice for non-real time needs.

If you already have a space station in Earth orbit, why do you need one in Lunar orbit too?

- Specialization and optimization, ie cost reduction, on each leg (up, across, down).
- Expansion, servicing flights to/from asteroids.

Why would you not seek to do your interplanetary burn direct from Earth orbit, like we have done with literally every single thing we've ever sent to Mars?

I would expect flights to mars to eventually be originating from both earth and the moon. Different missions, different needs. Plus the moon is also its own destination independent of mars.

Not being snarky, just wondering if there is some delta-V advantage to being higher up the well, but in a different (lesser) well.

I'm thinking payloads. Something mined/manufactured on the moon useful to mars. At least until we get good at mining asteroids.

Mars will likely require the following infrastructure: space station in earth orbit, space station in lunar orbit, lunar base, space station in orbit around mars, and then a mars base. Like military operations, it's all really about logistics. Can we squeak in a direct recon flight, sure, but more serious stuff will require infrastructure.

Toss in some local acquisition and processing of resources at some point. Ex H2 O2 -- for air, water, and fuel.

Comment Humans are more capable on site .... (Score 4, Interesting) 73

A human on site is far more capable than a robot. A robot will have far greater endurance at a site. Which is better depends on the mission, the tasks to be done.

Also a big part of these missions is to develop and test the tech necessary for manned missions.

Comment Frustration indexes have been used before ... (Score 3, Interesting) 36

Frustration indexes have been used before in other customer facing industries, in particular to determine if users are being over served or under served. A certain level of dissatisfaction is expected, if it's too low then too many resources are being spent per user. Ie wasting money. Maximizing revenue often involves a non-zero frustration index. Seriously, service that is too good is sometimes considered a bad thing.

Comment They want current contact info (Score 1) 42

"South Korea's law actually requires Apple to re-verify someone's age annually."

So they're concerned that, as time passes, a devious person will... grow younger?

They probably want a current verified ID, with the current address and contact info that comes with that. Ie. Also 15, 18, and 21 years olds may be required to provide different levels of info.

Comment Re: Not diversity hires (Score 1) 183

KBJ has undergrad and JD degrees from Harvard, where she edited the Law Review, clerked for Breyer, and was a distinguished federal district and circuit court judge on the D.C. Circuit, the country's "second highest court." THAT'S who you're using as your example of an underqualified diversity hire?

Actually, academia and political appointments tend to work very different from NASA. So that's not quite an all other things being equal comparison.

Comment We need to make the lawyers pay the penalty (Score 3, Insightful) 49

We need to increase the penalties

I think we first need to be sure that the lawyers actually paid the penalty themselves, and not passed it on to the client as some sort of expense. And if not passed on to the client, ensure that the penalty is not a business expense they can deduct.
