    If you want to know how far Elon Musk's Tesla Roadster has travelled then you can click on this link here. http://www.whereisroadster.com/

    It needed 500,000 litres of petrol equivalent rocket fuel to get up to orbit, but as it has traveled over 3.25 million Km as I write this, it is already heading to be the most fuel efficient and eco friendly car of all time.

    On the basis that it is exceeding 10,000 Kmh right now and that it will last billions of years, (unless it is hit by a meteor/asteroid/captured by aliens etc.) it will become the most long lived car of all time.




    EDIT: Apologies, duly edited to reflect that I said "vehicle" when I meant "car".

    Voyager 1 is a vehicle and will always be 40 years older.

    Voyager 2? It's carrying cargo in the form of the Golden Record, which has photos of Earth, audio tracks etc. Therefore it qualifies as a vehicle.

    Why I said Voyager 2, because it actually launched 16 days before Voyager 1.

    EDIT: I genuinely didn't see the one before mine! :D

    I'm right by 16 days ;)

    Comparing it's fuel efficiency when it will be basically floating in space is a bit moot. 500,000 litres for the 3.25M Km is hardly fuel efficient before it freewheels the rest of the way. It burned 15 l/100km so far.

    Seems that it's possibly Luna 1 that's the oldest vehicle in space - it was intended to orbit the Moon, but missed by 5,000km and entered a solar orbit, 59 years ago. Probably still out there somewhere!

    Speaking of space and speed... you could walk around Venus at such a speed that you are in constant sunrise/sunset/etc.

    When they realised it wasn't going to hit the moon they renamed it Mechta "dream" as it going to leave our planet far behind, off to wander the cosmos.


    Early probes were battery powered they are now silent forever, but later ones used solar panels. ISEE-3 and IMAGE were rediscovered by amateurs years after going silent.

    Alfred Hitchcock was nominated for Best Director at the Oscars five times and never won.
    1940 Rebecca
    1944 Lifeboat
    1945 Spellbound
    1954 Rear Window
    1960 Psycho

    He did receive an honorary Oscar in 1968. His acceptance speech, in its entirety, was "Thank you... very much indeed."

    Huskies have a lot of special adaptations for dealing with cold weather. For instance, when they sleep, they put their tails over their noses. The tails are specially adapted to act as warm air filters so the dog only breathes warm air.

    A pangolins tongue is attached near its pelvis and last pair of ribs, and when fully extended is longer than the animals head and body.

    2 stars in the cygnus system are set to collide around 2022 (give or take a year). They'll create a new start a and give off a red glow as bright as the north star... and all visible in the night sky.

    And some shmo will definitely say tis a sign that our world will end.

    The Biggest Star Ever Discovered

    UY Scuti

    From our point of view, Earth is pretty big compared to the size of a single human. But compared to even some of our close neighbors, our home is incredibly tiny. Let’s imagine for a moment that the Earth were an 8-inch diameter ball. At that scale, the Sun would be about 73 feet in diameter, which is a few feet more than the height of the White House. Our enormous, distant friend, UY Scuti, would be 125,000 feet in diameter, which is just a smidge under 24 miles. Remember that crazy Redbull-sponsored stunt a few years ago performed by Felix Baumgartner, who jumped from the outermost limit of Earth’s atmosphere back to the surface? That was 24 miles in the air. Now imagine a sphere that large. That’s how big UY Scuti is.

    "The light from those millions of stars you see is probably many thousands of years old' is a rare example of laypeople substantially OVERestimating astronomical numbers"

    most stars visible with the naked eye are within a few hundred light-years of earth. Deneb, in the constellation Cygnus, is probably the most distant you can see easily, at around 2,600 light years, and it is the 19th brightest star in the night sky

    On this theme,

    The skin on your feet grows fast enough on earth to replace all the wear and tear through friction, but the skin on your feet flakes off in chunks in space.

    In space, astronauts wear the same socks and underwear for a few days, so they have to be really careful taking off their socks at the end, lest flakes of skin float off.

    The more I read about the behind the scenes stuff, not just the media broadcasts with schoolchildren and ping-ponging water balls....
    It's really manky, manky stuff a lot of what they have to put up with, months at a time.


  • Registered Users, Registered Users 2 Posts: 11,812 ✭✭✭✭sbsquarepants


    That's just semantics. You can describe it as wide or as long but not both at the same time. If Donegal is one hundred miles long North to south and one hundred miles wide East to west, then its southern border can sensible be described as one hundred miles wide. Long would be more normal but it's clear from context what was meant.

    That makes a bit more sense, but wasn't clear to me from context, and I also wouldn't say it's particularly "sensible" to describe a line as 100 miles wide rather than 100 miles long!

    When astronauts sleep, they have a fan blowing at their face, to stop a bubble of CO2 forming around their head and killing them in their sleep.

    The more i read about the astronaut thing the worse it sounds.

    Not the most comfortable of environments alright. Space is also a bit of a misnomer with humans involved. "Confined space" might be the better term. If you ever get the chance to see the Apollo Command Module that took three man crews to the Moon and back, about the biggest(no pun) thing that will strike you is how absolutely bloody tiny inside it is.


    Consider one bench is removed and the camera is running a wide angle lens.

    About the same internal space as an SUV. Imagine living, breathing, eating and pooing inside an SUV for a week, with two other dudes. OK weightlessness adds some room, but claustrophobic isn't in it. The guy they left behind when two of them went to the surface have often been described as both missing out and "the loneliest guys", but in another way it must have been near bliss to have the thing to yourself.

    Many worry about Artificial Intelligence. I worry far more about Organic Idiocy.

    Scott Kelly's book is called "Endurance" for a reason.

    It's years and years of training for a mission in really not very nice conditions, for what seems like not super money, etc etc.

    These are real, "suns going down, better drink my own piss" hardy bastard type people.

    I heard yesterday that not only is urine recycled, but sweat, too... and (this to me is far grosser) so are nasal secretions.

    The sweat gets recycled through the dehumidifiers.
    The water reclaimers take all comers.

    On that one! - Every now and then, the toilet has to be maintained.
    If you do it wrong, a massive big bubble of urine/chemicals forms.
