This is so cool.
I've always felt bad about the Apollo 15 crew getting into hot water with NASA and Congress over the Postage Stamp Incident...their attempt to make a little money on the side through a private deal with a German stamp dealer. Several of the private deal stamp covers were brought along to the moon (presumably into orbit only, not down to the surface) together with a sheaf of "official" ones. The fallout once the private sale was discovered has tainted the crew for a long time.
So now we're talking about the very public sale of yet another Apollo 15 artifact. Seeing the article (before reading it) made me think maybe the Apollo 15 guys were in trouble again...
Fantastic...less toxic than hydrazine, easier to handle, higher density meaning longer lasting satellites, and presumably supports higher isp thrusters.
What this stuff needs is a decent name!
I didn't expect the Spanish Inquisition...
Right, so Watts x Seconds gives you Joules, as in the article.
If we're bringing in Japanese, then we should recall that a smidge is equivalent to a scosh.
What I got from this was that some creatures need a very stable environment in order to thrive. Wonder if humans are on that list.
And I don't even live in the UK.
Sounds like Larry Niven's "The Coldest Place" IIRC.
Just a random thought...adding back Pluto and its brethren (Ceres, Makemake, Eris, et. al.) then going in order from the sun, Pluto becomes the 10th planet...therefore "Planet X." Pretty cool.
Is straight from Kerbal Space Program. (Or was it the other way around?)
If you let loose your pyramid, won't it wander until it eventually makes its way out of the jungle?
I felt like I was sitting in the cockpit. What joy.
Also...that airspeed indicator photo was spot on.
Just over 1/2 a Saturn V.
When I first glanced at the screenshot from the old Asteroids game I thought I saw them slowly moving in random directions. My mind must have provided some imaginary animation.
Thanks for reminding me of the good times from 30+ years ago!
Vlad's reply was perfect. But in case it went over your head, AC, remember this is a British IT news site, and the Brits and USAnians spell words differently. Beware the language barrier:
fertiliser / fertilizer
colour / color
licence / license
At last, El Reg comes to my part of the world. Perhaps I can help! To wit:
1. I've got a Cesaroni J engine (might be 3G) that's yours for the asking, and the usual adapters for fitting different dia. vehicles. Only hitch is that I'm up in Seattle. Can't get these at Walmart, but the courier delivery guy did drop it off at my house, only after I promised over the phone to lie to his boss and say I was physically present when he dropped off (this hazardous material). So yes it's relatively easy to ship these in US of A.
2. My folks live in New Mexico, unfortunately, way up in Santa Fe. But they have lots of friends and might find you a place to stay down in Las Cruces. How many of you will there be?
3. Why bother with the Caribbean after the flight? You've got one of the most interesting places in the USA to explore. For starters, White Sands missile range is close by, as is Alamogordo. Both have missile or space museums... Then there's El Paso TX, go to the ('murican) Taco Bell there, it's surreal... If you time your visit right you might even get to visit the Trinity Site.
Squad ought to update the Mun to include caves and pits. As if driving on the Mun (or landing) isn't difficult enough already.
The point is, they're training a new generation of rocket scientists / program managers / engineers how to fly spacecraft. Doesn't matter that this has been done before, you need to start with a smaller scale project.
They're being very methodical, more tortoise than hare ("Rabbit" notwithstanding).
Stanene...nice woody sound.
Yes, L iquid OX ygen.
If they could burn all that fuel quickly and be on their way in one go, I'm sure they'd do it.
But, a bigger engine might not have been available, or they chose a small one (that burns fuel more slowly) to save weight. With advance planning, it's really no big deal to make many small burns to increase the size of your orbit.
Exactly, it's like predicting the weather. A commenter above mentioned "120km" as the altitude of doom. True. But sometimes it's a bit higher, say, 130km, depending on atmospheric conditions. Which we don't know exactly at all points of the atmosphere at all times. Hence, you just can't know where a gradually decaying, circular orbit will come down.
Far better to do a big burn at the end of the sat's life, to target the orbit to intersect the Earth at a safe spot.
My retriever not only points her nose at things she wants us to know about, she uses her eyes to point to what she wants. Look at the food item she wants, look at us, roll her eyes back at the snack... until we get the point.
>>They said it had left the galaxy.
I just can't stop chuckling at that.
>> Actual speed is about 80 kips, or about 2.5x faster than a pocket calculator.
If it left the galaxy, then its actual speed is in excess of Warp 6.
In 1999, leaving Seattle in late November, I remember seeing a bunch of dodgy-looking people stepping off the little subway train on their way into the exit of the airport while I was boarding the same train to get to the terminal. One young lady was very clearly carrying a (probably dummy) metal grenade, and she had just stepped off an airplane. I suppose she was one of the WTO protesters gathering for the "battle in Seattle."
What stuck in my mind was that she had apparently been allowed to carry this on an airplane.
Interestingly, on my way from Japan to the US in about 1990, I had nearly had an iron bell (more a windchime) confiscated because it was about the same size and color as a grenade. I had to beg the security guy to let me keep my souvenir.
If there's a risk of colliding the cleaner sat with the target, then just setup the approach direction so this collision would at least slow down the target...and contribute to its de-orbiting.
Alternative technology idea for the Swiss: orbit a large, yellow rectangular bit of material to get in the way of orbiting satellite targets. The target sat would hit the material and slow down, leaving a hole in the material. After a while it would resemble...
It's west of Hawaii.
I enjoyed Myst. It ran well on my PC, and I remember many pleasant hours spent solving the puzzles, with help from my brother (who in turn learned clues from his friends).
Fast-forward about 6 years, after my move to the Seattle area I learned the design team (Cyan) was from Washington State, and their Myst island had been inspired by one of the San Juan islands.
I've visited the spot by boat a few times (it's wonderful) and think about Myst when I do. The pictures here don't do it adequate credit:
Yes, but it took me just a few seconds to squint at your math problem and come up with 3.8, which is within 1/2 of 1% of the correct answer. Human brain does well with comparing sizes of things.
What time? 6.29AM EST or 7.29AM EDT? We're on daylight savings time don't you know.
The F1 engines in the Saturn V burned Liquid oxygen and RP-1 aka kerosene...basically jet fuel. So the exhaust was no more toxic than what you breathe at an airport.
LOX/RP-1 is nowhere near as toxic as the hypergolic fuel combos used by the Gemini's Titan II (pre-Apollo but only just), and by the Chinese space program even today for their Shenzhou manned missions. But after 44 years in the sea, I can't imagine any traces of the fuel would be left regardless of what type it was.
Would you be taking your boxed lunch before or after the war?
John Smith 19:
"9/11/01 was thirteen years ago."
12 years ago?
Steve Davies 3:
"Don't you mean 11th September 2001
Using the proper date format."
Interesting, I always though the attackers on that day chose the date "9/11" because it's the phone number Americans dial to get emergency services, 9-1-1, so that the date would be more memorable. So in this case the "correction" wouldn't be needed. Or I just missed the joke.
Seiko Matsuda, really popular Japanese celebrity in the 80s. Haven't seen her face since about 1988, thanks for the face from the past.
When Steve mentioned that die-rolling in video games just didn't have the psychological impact of real dice, I figured digital dice...with accelerometers and bluetooth...could be a great addition to such games.
Looks like someone already made a patent for it though:
Have your avatar sit at your desk, go to meetings, visit the toilet...
She made a mis-steak.
Where can I get an Alan Turing minifigure?
I feel this way too. His career--running his own space program and developing awesome, new-tech cars--is straight from an 11 year old's dream about their own future. And damn it, he's succeeding. He is my inspiration.
That's already happening...you wouldn't believe how many kids in my son's elementary school are named "Aiden" and "Preston."
We've got erudite rocket science professors giving lectures on how this works and why it matters.
Also a few retards weighing in too.
But geothermal also works at night.
See the recent article in this website about using ground-based lasers to help de-orbit space junk. Perhaps one could use the same system to nudge satellites out of the way of an impending collision. As you say, it takes just a small nudge a few days in advance to do the trick.
>Here they used Pallas, Zeus, and Poseidon. I got some blank stares from the CIT crowd (Philistines, the lot of them ;-) ) when I suggested Offler, Om, and Nuggan
>I'll get me coat!
Ahem, Quezovercoatl. As in, "I'll get me overcoatl."
Regardless of whether I already knew about Newton's Laws before going into university, I would rather learn those laws from Feynman than anyone else. I'd love to hear his take on them, and how they connect to everything (physics, history, etc.). And you don't get Feynman at most high schools.
"Nearly 50 years ago" -- Sorry, I was born days after Apollo 11 and I'm not that close to 50...the date range for Saturn V flights was more like 40-45 years ago.
"Plummeted into the sea at 5000 mph" -- The terminal velocity for a spent stage 1 booster would be much closer to 500 mph than 5000.
Seeing the colors and composition of life on a planet, from a great distance...if this technique works, it will be the next best thing to actually hearing aliens with the SETI program. What could be more inspirational to would-be space explorers?
We're opening up a whole new chapter of science, one that astronomers and planetary scientists have been dying to read for as long as those sciences existed.
