Comment Consider the facts (Score 3, Insightful) 130

I'm sure I am preaching to the crowd here, but the crash should be considered in light of the following facts:
- SpaceX customers still pay for the entire rocket, there is no discount applied yet
- All other competing rockets do not have this capability and burn up on re-entry
- Every landing attempt provides new and unique data that can be used for continuous improvement
- The primary mission (what they are being paid for) was still accomplished

Comment The missing perspective from this thread (Score 1) 190

This is going to get downvoted to oblivion, but here it goes.

Normal people do not care about software updates. They care even less about security updates. They are on their contracts and happy to pick up a new phone every 2 years or so, and there is little elapsed time before their phone's current OS will go out of fashion.

Nerds do care about this stuff (myself included). This is the specific reason I buy the Nexus line. I have had non-Nexus devices before, and gotten bored (rather than frustrated) over lack of OS update, so I've flashed custom ROMs.

Comment WebView (Score 1) 629

I read that Lollipop will include webview as part of the Google Play Services framework, which is Google's cloud-based framework that they have been moving more and more Android services to.

Unlike app store updates and normal Android system updates, Google Play Services works as a silent push update, so phone providers and manufacturers cannot block the update. I'd hazard a guess and say this may have something to do it.

NASA is providing incentives -

http://en.wikipedia.org/wiki/Commercial_Crew_Development
Understandably these are to meet NASA's requirements (which makes since, since they would be the main customer for the services anyway), so they don't just want to dole it out without a decision process.
There's also stuff like the Lunar X prize, but none of this is in the magnitudes you are talking about (good luck getting that through congress).

Sorry -- slightly unhelpful post in that I don't have a link, but according to some interviews I've seen with Elon Musk much of it is to do with modern engineering. One of the examples he gave (which was during a totally non-sciency talk show) was about how they processed and bent a particular type of metal used in the Falcon.

Comment Re:Not sure about the recovery test (Score 1) 125

Believe the purpose of landing it in the ocean was to actually test the deployment of the legs on the rocket (this is the first model where they've included the legs). So basically just launching it, extending the legs out and then testing if the first stage lands in the ocean properly with the legs deployed.

Also perhaps already mentioned in this thread but since they upgraded Falcon to 9 to v1.1 they have continued to offer the old v1.0 payload to customers, reserving the additional payload 1.1 is capable of for testing reusable components.

Comment It's a problem, but one Google has been working at (Score 1, Informative) 289

Things Google have done recently to combat fragmentation:
- Announced the release of the Android PDK, a preview-esque version of the new OS available to manufacturers before the official release hits source
- Begun de-coupling official Google apps from the OS and therefore from the update cycle (e.g. Google keyboard, IIRC Gmail and Maps, etc)
- From a 'smoke and mirror' perspective, kept the Android codenames the same across Jellybean (4.1 and 4.2)
- Most recently, "updated" Android completely without actually updating it via pushing updates to core apps and services like Play Store, Music player, sync APIs, etc.
- Adding to above: Held off on releasing a numbered Android update to let the natural cycle for replacing handsets to continue (so people with Android 2.1 phones hit the end of their contracts and buy 4.2 phones)
.. and certainly much more. I'm thinking the #1 point on the PDK will be significant as we have yet to see the real effect of this. Previously the source code for new Android versions would be released to both the public and manufacturers at the same time, so you'd have teams like Cyanogenmod quickly port and do their own QA on releases using stock Android, while manufacturers had to update their custom UI's against the new version, go through their own rigorous QA processes, go through telco QA processes and timeframes, etc. The end result was updates being released by community teams (excluding Nexus devices) long before manufacturers did, leading to much discontent.

Here is the "official" Mars One answer to bone issues (site seems to be down now so copy and paste from Google Cache):
Prolonged weightlessness causes osteoporosis, which can be reduced by exercise and medicine. Research onboard the International Space Station has led to even better and more effective training programs being drawn up, and new machines being made specifically for astronauts. Conjointly, there have been major leaps forward in medications capable of partially preventing declining calcium levels.

Recent study about 14 ISS astronauts, who were 4-6 month in space, showed a maximum bone loss of 1.5% / month in the most vulnerable (from bone loss point of view) region - the hip. Therefore the bone loss after arriving on Mars, after a 7 month flight, would be in the worst case scenario 10.5%.

When they arrive on a planet with 62% less gravity, they would have 100% more bone density compared to humans under earth gravity.
