Uhhmmm, they've done way more than show pretty renders already:
It WAS always expected to last more than 3 months. 3 Months was just it's primary mission time, things it "had" to get done before the winter and the possibility of losing the rover due to lack of power from dust on the solar panels. Plans to survive the winter had already been made before the rover arrived on the planet though. But 13 years is certainly something no-one would have believed a decade ago. And I'm sure we can forgive the lil' chap his memory problems. I'm sure we all get those senior moments once we age.
Knowing El Regs style that was put there just to annoy us and get comments like yours! Congratulations, you took the bait.
Not exactly. It's about controlling and tracking and shaping "community" in Facebooks favour. Because forming actual community involves actually looking people in the face.
Actually not all that much of a problem if people would only just get over their paranoia over what constitutes nuclear waste and reworking of used fuel bundles (yes, you get plutonium, no you can't just build a bomb out of used fuel plutonium as it'll take a LOT of processing to remove neutron poisons and then you are left with the wrong plutonium isotope.
Not actually as big a problem as it was first made out to be and pretty much succesfully solved by tighter regulation on emissions from factories and power plants.
Again, tighter regulations (and bans) on use of CFCs has largely solved this issue and the latest evidence indicates the Ozone layer in the atmosphere has been recovering.
Jup there's a problem. Not easy to solve either
Shouldn't be a problem and isn't a problem in a lot of countries.
Yes, we face a lot of problems as humanity. No, solving them won't be easy. It's not just the rich nations taking the hit for this. Every nation on this planet benefits from access to space.
What you hear is the lobbyists of the big telco's talking. It's very obvious this guy has only listened to the guys buying his lunch and dinner.

Well done NASA goon. Exemplary action...
it looks like a convenient way of forcing people onto the newest build of its

Theoretically deep stall IS possible with a "standard" horizontal stabilizer but simple geometry means that it can only be unrecoverable if the stabilizer is above a certain height, a normal and/or cruciform tail is normally below this height.
What happens in a deep stall is that the horizontal stabilizer moves through the dirty stall turbulance of the main wing and thus the elevator is no longer effective to control the altitude and the nose is no longer pushed down. Thus if the centre of aerodynamic force and the centre of gravity align the plane does not recover from the stall.
The why of how this happens can be a long story but the gist of it is that any wing stalls at 15 degrees angle of attack. Maybe a few degrees more or less depending on flightlevel and flaps config. One can then draw out the wake zone of the stalled main wing and the position of the stabilizer relative to the main wing and determine when the stabilizer is within the wake zone. With a normal tail when you draw this wake zone in a stalled situation the tail is below the wake zone in all but the most extreme stall angles and the pilot and aerodynamic forces have plenty of time to correct the situation. In a T-tail design the tail is higher up and thus closer to this wake zone. Thus control authority is lost for much lower stall angles. And additional problem is that in a T tail the tail has to be above the wake zone for the aircraft to regain normal flight and thus has to transition back from high angle to lower angles, while a traditional design does not have this problem.
The problem with keeping XH558 flying is that by now she had many more hours on her than any other Vulcan had ever made. Any aircraft in service has problems, graded from minor expected easily fixed problems down to disastrous but completely unknown problems. The Design Authority basically has to make an assesment as to how many unknown potentially catastrophic problems exist in the airframe and mitigate any known or known potential problems. Due to XH558s lifespan and flight time the amount of unknowns starts climbing as there is no "comparable lifetime" airframes to make an assesment against and cross check measurements against one another. The B-52 can be kept in the air because there is a large pool of them to cross-check and reference. Same with other "old workhorse" planes like the A-10 or the DC-3. Keeping a unique, single example, complex plane like the Vulcan flying just started to take too much time and become too much liability for the design authorities. Added to that the skills needed to keep this sort of design flying started to die out within the companies as people retire or die. Modern aircraft are built differently and follow different rules and regulations requiring different skills and knowledge. It's tragic but thats the way it is.
Even the short haul 737s used to have plenty of first class seats. Nowadays the seatcount is usually reported in an "all economy" config for a short haul plane. And most airliners operate their planes in that config too.
There is enough evidence to show chemical weapons WERE used. There is debate as to whether it was of a type and grade available to Assads regime. I'd find it just as believable it was the US or Russian forces under a false flag operation. I've also not seen any indication as to how the weapons were supposedly delivered. Air attack? Artillery? Large vats opened upwind?
I'd be all for a license to use the Internet, with just a basic requirement to show that you actually know how to think and breathe at the same time. Anonymity is however much more important than people seem to realize. I would NEVER advocate for any sort of internet where anonymity isn't available.
Mostly in how the court is going to interprit the actions of "volunteer" moderators and their affiliation/work for the website. It could have heavy repercussions for how ad-supported sites run their bussiness and how much liberty/power they grant their moderators. I can foresee many forums banning their moderators from posting any content under a moderator account just in case anyway.
In any case, posting "questionably obtained" materials as a moderator is a stupid thing to do anyway.
Earths atmosphere is roughly between 200 and 250 K in the upper mesosphere. That's only a 100 degrees K difference. Yet returning vessels easily experience thousands of degrees of shock heating. A hundred Kelvin isn't going to change that much at all.
I'm just waiting for a blackhat or pentester to penetrate their servers and open every garadget door in the world simulatinously. Or makes them do a dance.
Too bad it won't be going anywhere. Because once Trump gets ousted (I highly doubt he'll make it to a full term without either getting impeached or killing is all in nuclear fire) NASA budgets and budgets get porkbarreled again, and the SLS will get scrapped for the next inane, rehashed, stupid idea that gets the US nowhere fast. Meanwhile India and China are catching up and SpaceX and possibly Blue Origin are making the entire US space program look like idiots.
How does any board ever approve of such a shit name?
And more importantly how the flux is Yahoo! still a thing? It's a brand that deserves to be taken out behind the shed and shot. Repeatedly. At close range. With a large bore shotgun. Using deer slugs. After receiving a damn good beating with a baseball bat.
Given the limited space on the deck and the spread of landing points seen in the landings so far I doubt they'd have enough confidence to land more than one core on the same deck. Nor would I suspect they'd want to due to vibration/noise damage to the core already on the deck when a next one comes down. Do not underestimate just how much damage acoustics from a rocket engine can do. It's one of the main problems to solve in silo launched ICBMs for instance. Without mitigation they would shake themselves to bits before leaving the silo.
As mentioned before SpaceX has noticed the first stage has a tendency to "walk" across the deck in rough seas between the landing and the welding crew getting there to weld it to the deck. The stage doesn't stay where it lands, so one could end up taking a topple after a successful landing. Next to that there is also the problem that the stage is never really centred on the deck after the landing and there is no provisions on the barge to move it to the centre (or to the edge of the deck to hoist it onto a support ship to clear the barge). Thus it makes perfect sense to design something that can move the core to the centre of the ship and hold it there until the support crew can swoop in to weld it to the deck or transfer the core to a support vessel. My guess is transfer to a support vessel is actually the long term plan, so that the barge can stay out at sea while the much faster moving support vessel shuttles the first stages back to port)
For falcon heavy the centre core will either not be recovered or if it is it will land MUCH further out than the booster cores. By the time the centre core stage separates it'll be moving at probably about 1.5 km/s, so it takes some serious burning to get it back to a barge the booster cores can reach. (But as said before, the booster cores are planned to return to the LZ pads at the spacecentre) More likely they'll have a barge much further out, so the centre core can use the atmosphere do some of the breaking and stay on a mostly ballistic trajectory.
Then again, I'm not a rocket scientist. I just play one on Kerbin.
No shit Shirley
This would be my "most likely option" as well. It's clearly not design to be shockproof and fireproof, meaning it's not intended to be in the line of fire as the rocket comes down, thus it has to come into action afterwards. The design overall seems to be low enough to fit under the engine bells. I am wondering a bit if the jacks would fit under the legs though.
Different platform. Count the clamping arms.
Cops nowadays have specially shielded bags to put evidence phones into, to prevent remote access and wiping. Then the search/download is usually done inside a protective faraday cage room/case/bag to prevent the phone from receiving external wipe commands.
And how are you going to send the wipe command stripped of all your possessions and clothes, stuck in an unelasticated tyvex coverall and thrown into a holding cell?
Something known in fluid dynamics engineering since a century, applied to a wine bottle.
You could NOT store your payment information in your ebay account. Then what are they going to do with it? Good luck with the knowledge I ordered a 10 pack of NRF24L01+ knockoffs yesterday. And a batch of cheapo illuminated momentary push buttons last week.
The problem is that this sort of ad runs through an ad-slinger. So a "good reputation" website could still end up slinging ads. (Even the Chocolate Factories ad networking has been known to sling malware).
Time for ad networks (or their customers) to demand an end to all these ridiculous script slinging ads. There is no need for them.
The answer to this is, yes...
There is plenty of evidence to show that even though there are more and more of these ban lists and blocking filters around the problem of kiddie porn or children viewing porn has not diminished one bit.
The only reason I can find is the afformentioned control over what citizens can see and access.
The cynic in me reads this mostly as: We are locking down Android even further to make it even less customizable and more like iOS. Because screw our original idea about what android should be.
This kind of science restores just a little bit of faith that humanity might one day actually achieve something noteworthy and the future will not end in fiery death for us all.
Li-Po most likely, not Li-ion. Very different beast. Li-ion is usually in a hard case that is quite indifferent to altitude changes, Li-Po tends to be packaged in soft foil package that flex under the slightest of pressure change. This soft foil is great for allowing flexibility in producing different size cells quickly, but a headache for designing a robust cell.
I've seen plenty of contractors use Li-ion based tools without problem. And if there is one thing you can be certain of it's that the average contractor is NOT careful on his tools and subjects it to PLENTY of knocks and drops.
Li-Ion cells in a hard case are very very rarely a problem. You have to SERIOUSLY mistreat the average 18650 cell before it combusts and even then they are usually rather benign. It's the more energetic cousin Li-Polymer in a soft foil wrapped satchel that is the more dangerous flamey option/problem.
Actually no, it gets worse for anything humans would still consider breathable low pressures. Minimum breakdown voltage occurs at roughly .2 mbar. Only once you start getting close to hard vacuum does the breakdown voltage suddenly climb back to infinity.
I really don't get why people think dielectric strength gets better at lower pressures. It's demonstrably not true and this has been known since the 1890s
I would have to add though for a few 1000 meters to make a difference it would have to be a rather low margin design though..
Rule of thumb is about 1kV per millimeter of arc length at sea level. At altitude this can be several millimeters per kV, so if the design used has an inductor creating high voltage spikes in the rectifier circuit it's totally possible to get enough voltage somewhere to arc.
Well, the 0 height reference used in the Netherlands is called NAP (Short for Normaal Amsterdams Peil, Normalised Amsterdam Level, which is used as the reference level for all height measurements in the Netherlands and several other countries.) SO it's not all that hard to argue Amsterdam (almost by definition) is at 0 meters NAP.
@Voyna i Mor,
clever people have done this out of self preservation because idiots seldomly kill themselves. They are way too stupid for that. They tend to take others with them.
@AC, lets just say all parties involved were consenting adults ;)
Duct tape actually makes for a terrible gag. It's pretty much impossible to silence someone in such a way they won't be able to work it loose in short order.
The decision to do that is however not actually NASA's to make. It's budget and what it has to spend those on is pretty much decided by the US government and it can't just go around and yank a bag of money from one project and spend it on something else.
The thing is, all current data points to the current climate changing. Global weather patterns are shifting, with warmer air and ocean currents reaching further north than we have seen in the last 150 or so years of records. Understanding the why is important. Whether it's anthropogenic or not. Since the best way to study these patterns is from a space vehicle NASA is one of the logical choices for earth observation research. And thus why it's been running these missions.
BTW, living on the moon is a massive waste of resources. There is not much useful there and the Moon has a pretty deep gravity well, requiring lots of resources to get things back off the surface. Bigger spacestation, maybe. Working the astroid belt for resources? I still have my doubts that's ever going to be profitable.
Biggest problem still is NASA's budget and focus gets pushed around way too often and way too suddenly, putting a lot of valuable research down the drain.
The problem is that NASA is using that 50 year old tech BECAUSE the budget is insufficient to get something properly new researched and designed. Compounded to that the problem that their budget is subject to change without notice every 4 years so setting up a long term research project often ends up being completely useless as budgets get cut right when the actual prototyping and testing starts. This has lead to a LOT of promissing research ending up in the bin at NASA and has given us the overly conservative program culture we see today. Want NASA to boldly go forth and build the next big thing in space? Give them a large budget increase and make a law that prevents ANYONE (even the next president, congress or senate) from decreasing it before the program is either succesful or the budget is spent. And then make sure the standard porkbarreling that happens now doesn't happen either. Because that's another massive moneypit with no actual benefit.
I don't think you'll be surprised to hear that such a bussiness/product already exists and the market (especially if you operate globally) is not all that niche in fact. There is already too much competition in that market to really make much of a name for yourself.
Because having an extra failure mode being your engines fall off is a good thing...
Or risking a helo crew to snag an engine block out of mid air...
Or having to lug up the extra dead weight of a heatshield and parachute instead of extra fuel that also gives you extra options in case of an engine out scenario...
Sounds to me like they needed a: "Look, we do recovery too" marketing blag that wasn't too similar to SpaceX
Boeing and Lockheed have always outsourced a lot of their spaceverhicle design to other firms. They've always operated as a sort of "central contractor", farming out the smaller sub jobs to their own subcontractors and then integrating the final results. They've never had all the inhouse knowledge to do it all themselves.
I think he's talking about Geert Wilders, one of the politicians with a shot at becoming the prime minister of the Netherlands, and the whole kerfuffle happening between turkey and the Netherlands right now. Since the Netherlands refused a turkish minister into the country because there was evidence of a real and direct danger to public safety
the high goatfuckerErdogan decided to call the Netherlands a Nazi remnant and Fascist regime. Then went further off the deep end by saying the Dutchbat forced murdered 8000 muslims in Szrebrenica. Now another government official is topping that by saying we sold the childrens organs for profit and ran a human trafficing scheme over there...
"Is the Netherlands the next to wake up and reject smartass thinking?"
I highly doubt it. Thanks to a well timed diplomatic row with Turkey the current prime-minister and his party (VVD) have managed to suddenly work themselves back up in the polls. There is a good chance it'll be bussiness as usual after today. (It's election day in the Netherlands on the day that is today the 15th of March in case anybody was wondering)
--> Because honestly even if the PVV where to get the most votes I doubt anything is going to change for better or worse anyway. I'm not voting for any of the big parties in any case -->
MS hates it's users. It doesn't want to sell OSes anymore.
Even if they stand to make 100 pounds per domain, that's still 40k domains that need to sell just to recoup costs so far. Are there actually enough
suckerscustomers in this world looking for a .mail or .home adress?
@Skippy, sure, if you want to call the almost up to the job conversion of a helicopter to a sort of AWACS role to be an AWACS capability. A helo simply doesn't provide the same kind of coverage a fixed wing craft like an E-2 can. Which they could have easily deployed (and operated much more cheaply per flying hour) had they built a cat'n'trap ship.
