    [–] The recovery of Oppy - 2028 NeilFraser 12 points ago in SpaceXLounge

    Star Trek: Enterprise featured a fence and a monument in their memorial to the Pathfinder rover.


    [–] Could two-child policy save India from overpopulation? NeilFraser 13 points ago * (lasted edited 4 days ago) in overpopulation

    The current birth rate in India is 2.3. Replacement birth rate is 2.1. A birth rate of 2.0 would result in a very slow decline.

    Furthermore, a two-child policy (if enforced) would result in a lower birth rate than 2.0, since not all couples would opt for the maximum. Urban couples already are at 1.8, so this policy would mostly just put a cap on poorer rural couples, who are currently at 2.5.

    [–] What would happen if nuclear fusion power generation were to be commercialized? NeilFraser 9 points ago * (lasted edited 5 days ago) in overpopulation

    Assuming it is the best case for fusion (cheap, basically unlimited energy, with short-term waste), that would completely change the current equations.

    1. Cheap clean power means no more greenhouse gasses. It also means we could pull the existing CO2 out of the atmosphere (essentially un-burning coal). Global warming would be a solved problem.
    2. Cheap unlimited power also means desalination at epic scales. Imagine unlimited fresh water. Pump this into deserts and croplands expand tremendously. We could probably double the amount of food available.
    3. Quality of life also goes up with more affordable transport, air conditioning, heating, etc.

    However, if the advent of fusion power doubles Earth's carrying capacity, that just pushes the population crisis out by another 50 years. Then we are right back where we started.

    It's worth pointing out that this is exactly what has been happening for the past two hundred years. People have looked at the current state of the world and predicted imminent starvation. But every time, some technological miracle appears that doubles food production. Then doubles it again. Nitrogen fixation, the green revolution, etc. I hope that something like fusion will appear and save us once again (for a time). But there is no guarantee of that. So limiting population now would seem to be a prudent step.

    They will choke on their own words in a likkle bit

    No they won't. I talked with engineers designing Orion's TPS who were completely unaware of Dragon's off-center TPS (despite the latter being public on SpaceX's website). I talked with SLS program managers who were completely unaware that Falcon 9 was (at the time) successfully soft-landing in the water. It's not a matter of choking on their own words, its a matter of being so deeply embedded inside the NASA information bubble that they've no awareness regarding what's happening outside. They are just casually dismissing what appear to be fantasy paper rockets.

    The only person I've seen escape this bubble is Chris Hadfield. He made some very dismissive statements regarding Falcon/Dragon as he was retiring from NASA/CSA. But now he regularly live-streams commentary of SpaceX launches.

    [–] how about THIS! NeilFraser 1 points ago in KerbalSpaceProgram

    I don't really understand why posts like this and this get removed from this sub.

    [–] New Laws Forced Sex Workers Back On SF Streets, Caused 170% Spike In Human Trafficking NeilFraser 4 points ago in sanfrancisco

    I think the stumbling block is money. Yes, a website could be hosted from Belarus. But they would be unable to sell advertising to US companies or accept payment from US credit companies.

    Such a site probably involves a lot of man-power; dealing with moderation and complaints. The only viable option I can think of would be an entirely volunteer-run website.

    [–] Good ol' movie breakfasts [OC] NeilFraser 14 points ago in funny

    It's ok, today is your husband's last day on the police force. From tomorrow on you'll be able to enjoy relaxed breakfasts together that only retired people have time for.

    [–] What’s the dumbest shit someone ever said? NeilFraser -7 points ago * (lasted edited 17 days ago) in AskReddit

    The best source I can find is:

    The original source is The Hill, a print newspaper that doesn't have online archives going back to 1997. That said, there are also no sources I can find where anyone denies that this event took place. I also personally remember the story when it broke in 1997, so it's not retroactively invented.

    Edit: thanks for the downvotes, guys.

    [–] What’s the dumbest shit someone ever said? NeilFraser 64 points ago in AskReddit

    That's easy: 3.048 meters by 3.048 meters. Not an unreasonable question for those of us who are not American.

    [–] Have You Had A Question For Jim Lovell (Apollo 13) For A Long Time? This Is Your Chance To Get It Answered! NeilFraser 2 points ago in spaceflight

    Probably when the parachutes opened. One of the fears was that without heaters they'd be blocks of ice. After the parachutes open, there isn't a whole lot to go wrong; Liberty Bell 7 notwithstanding.

    [–] Japan Launches Satellite To Produce World’s First Artificial Meteor Shower NeilFraser 1 points ago * (lasted edited a month ago) in science

    It is for the Tokyo Olympics. The opening ceremony invariably comes with a massive fireworks show. But since fireworks are traditionally Chinese, the Japanese want to bring things to the next level.

    [–] Soyuz 4 & 5: The First Crew Exchange in Space - 50 years ago NeilFraser 3 points ago in spaceflight

    The probe of the Soyuz 4 docking system entered the drogue of Soyuz 5 at a speed of just 25 centimeters per second as the crew of the latter ship made (by today’s standards) a vulgar sexual remark.

    This remark is often cited, but never quoted. I'm curious, what did they actually say?

    [–] They are doing it again, but bigger this time! CERN teaser for the FCC NeilFraser 25 points ago in EngineeringPorn

    Sorry, you're right. The comparable time in the SSC's timeline was a third of a century ago.

    [–] They are doing it again, but bigger this time! CERN teaser for the FCC NeilFraser 36 points ago in EngineeringPorn

    The FCC is roughly equivalent to the Superconducting Super Collider that the US started building, then abandoned, back in 1993. If it's built, we'll finally get what was promised a quarter century ago.

    [–] Iranian satellite fails to make orbit. NeilFraser 29 points ago * (lasted edited a month ago) in spaceflight

    Reporting from the same people who claimed the Space Shuttle traveled at "nearly 18 times the speed of light".

    Edit: I reported the "escape velocity" issue to Reuters and they have striped the phrase from the article.

    [–] My wife finally received her green card! It has been a long hard fight, but she did it! So close to becoming a U.S citizen! NeilFraser 16 points ago * (lasted edited a month ago) in pics

    Not everyone requires a medical exam. I'm Canadian and was never asked for one.

    Edit: Weird, based on the comments below I appear to have been an exception. [cough] Guess I slipped through the cracks. [cough] Oh well, no harm done. [cough, cough]

    [–] Google street maps waving to Bing NeilFraser 3 points ago in funny

    In that case they could equally well have called it "King", among a few other options.
