If you're fixing to go to the Moon

What a groovy thing:

Between the Moon and Earth, there came a point where the gravity of the approaching body became stronger than that of the receding body. When this point of gravitational equality was reached, it was customary for mission control, and especially those concerned with flight dynamics, to switch their frame of reference from one world to another.

However, because the Moon itself was in motion around Earth, the numbers representing the spacecraft‘s speed and position appeared to jump. Journalists, more used to figuring out the trajectories of political figures rather than those of spacecraft, found it difficult to make sense of this change in the velocity figures being fed to them by the NASA public affairs people, and some got the impression that a ‘barrier’ was being crossed and that this must surely be felt by the crew.

Mike Collins later related how Phil Shaffer, one of the flight dynamics controllers in the MOCR struggled to explain the truth to reporters as Apollo 8 entered the lunar sphere of influence: “Never has the gulf between the non-technical journalist and the non-journalistic technician been more apparent. The harder Phil tried to dispel the notion, the more he convinced some of the reporters that the spacecraft actually would jiggle or jump as it passed into the lunar sphere. The rest of us smirked and tittered as poor Phil puffed and laboured, and thereafter we tried to discuss the lunar sphere of influence with Phil as often as we could, especially when outsiders were present.”

As a homeward-bound Apollo 11 crossed the imaginary line between the gravitational spheres of influence of the two worlds, Capcom Bruce McCandless called the spacecraft to inform the crew: “Apollo 11, this is Houston. Stand by for a ‘mark’ leaving the lunar sphere of influence." He then indicated the moment’s passing, “Mark. You’re leaving the lunar sphere of influence. Over.”

Collins saw a chance for some mischief. “Roger. Is Phil Shaffer down there?“ The FIDO console was being manned by Dave Reed rather than Shaffer. “Negative.” said McCandless, “but we've got a highly qualified team on in his stead.”

“Roger. I wanted to hear him explain it again to the press conference," teased Collins. “Tell him the spacecraft [definitely] gave a little jump as it went through the [equigravisphere].“

“Okay. I'll pass it on to him. Thanks a lot," said McCandless, “and Dave Reed is sort of burying his head in his arms right now.”

One line that's always bugged me in the otherwise generally excellent From the Earth to the Moon:

It is the biggest rocket anyone has ever seen, a behemoth intended to transport men beyond the influence of the Earth.

What, the Moon isn't under the influence of the Earth?  Anyway, NASA defined the equigravisphere as 40,000 statute miles (64,374 kilometers) from the center of the Moon.  Earth's gravity is still there, just a little less than it is in Houston.  A frame of reference to help them figure out where they're going, is all...

To Pretend To Go Where No Man Or Smurf Has Gone Before

Launch and TLI were yesterday, today has Apollo 11 doing a midcourse correction and some TV.  In honor of that, here's some Jules Verne:

"Man began by walking on all-fours; then, one fine day, on two feet; then in a carriage; then in a stage-coach; and lastly by railway. Well, the projectile is the vehicle of the future, and the planets themselves are nothing else! Now some of you, gentlemen, may imagine that the velocity we propose to impart to it is extravagant. It is nothing of the kind. All the stars exceed it in rapidity, and the earth herself is at this moment carrying us round the sun at three times as rapid a rate, and yet she is a mere lounger on the way compared with many others of the planets! And her velocity is constantly decreasing. Is it not evident, then, I ask you, that there will some day appear velocities far greater than these, of which light or electricity will probably be the mechanical agent?”

“Yes, gentlemen,” continued the orator, “in spite of the opinions of certain narrow-minded people, who would shut up the human race upon this globe, as within some magic circle which it must never outstep, we shall one day travel to the moon, the planets, and the stars, with the same facility, rapidity, and certainty as we now make the voyage from Liverpool to New York! Distance is but a relative expression, and must end by being reduced to zero.”

The assembly, strongly predisposed as they were in favor of the French hero, were slightly staggered at this bold theory. Michel Ardan perceived the fact.

“Gentlemen,” he continued with a pleasant smile, “you do not seem quite convinced. Very good! Let us reason the matter out. Do you know how long it would take for an express train to reach the moon? Three hundred days; no more! And what is that? The distance is no more than nine times the circumference of the earth; and there are no sailors or travelers, of even moderate activity, who have not made longer journeys than that in their lifetime. And now consider that I shall be only ninety-seven hours on my journey. Ah! I see you are reckoning that the moon is a long way off from the earth, and that one must think twice before making the experiment. What would you say, then, if we were talking of going to Neptune, which revolves at a distance of more than two thousand seven hundred and twenty millions of miles from the sun! And yet what is that compared with the distance of the fixed stars, some of which, such as Arcturus, are billions of miles distant from us? And then you talk of the distance which separates the planets from the sun! And there are people who affirm that such a thing as distance exists. Absurdity, folly, idiotic nonsense! Would you know what I think of our own solar universe? Shall I tell you my theory? It is very simple! In my opinion the solar system is a solid homogeneous body; the planets which compose it are in actual contact with each other; and whatever space exists between them is nothing more than the space which separates the molecules of the densest metal, such as silver, iron, or platinum! I have the right, therefore, to affirm, and I repeat, with the conviction which must penetrate all your minds, ‘Distance is but an empty name; distance does not really exist!’”

Then he let on it was all a hoax, just like what the Smurfs pulled off...

Einstein's Younger Brother

Brothers in space!

"So, where[as] I used to be just 6 minutes older, now I am 6 minutes and 5 milliseconds older," Mark Kelly said Tuesday (July 12) during a panel discussion at the ISS Research & Development 2016 conference in San Diego. Scott Kelly also participated in the panel, which was moderated by CNN TV personality Sanjay Gupta and webcast live. "Now I've got that over his head."

Mark Kelly is also a former NASA astronaut; he logged a total of 54 days in orbit over the course of four space shuttle missions between 2001 and 2011. But Scott Kelly's greater exposure to space radiation could end up aging him prematurely, Mark joked.

"So if 10 years from now, I look like I'm 60 and he looks like he's 80, you'll know what happened," Mark said. (The brothers are 52.)

"Mark got Botoxed, is what happened," Scott shot back, drawing a laugh from the audience.

How odd that NdGT never mentioned botox...

Like Rocks From A Highway Overpass

Oddly enough, Samuel and I were discussing the odds of something like this just today:

One afternoon in 1954 Ann Hodges of Alabama was napping on her couch when a meteorite the size of a software [ed note: softball, or MS Office bundle?] came through the ceiling, bounced off a radio and hit her in the thigh. She escaped with a giant bruise, but the meteorite inflicted much harsher damage in an unexpected way. The Air Force took the meteorite. Hodges and her husband Eugene fought to get it back, but their landlord, Birdie Guy, said the meteorite belonged to her and she sued to get it back. She settled with the Hodges, taking $500 in exchange for the rock.

Good thing he never naps these days...

Speaking Of NASA Data Geeks

Stone knives and bearskins:

Here's a challenge...

Develop a system that can control a 13,000 kg spaceship, orbiting at 3,500 kilometres per hour around the moon, land it safely within metres of a specified location and guide it back from the surface to rendezvous with a command ship in lunar orbit. The system has to work the first time, and minimise fuel consumption because the spacecraft only contains enough fuel for one landing attempt.

Do this with a computer that has barely 5,000 primitive integrated circuits, weighs 30 kg and costs over $150,000. In order to store your software, the computer doesn't have a disk drive, only 74 kilobytes of memory that has been literally hard-wired, and all of 4 Kb of something that is sort of like RAM.

Sounds daunting?

That's the task that faced Peter Adler and Don Eyles of the MIT Instrumentation Lab who were responsible for developing the software for the Apollo Lunar Module. Their system worked, but almost caused the first moon landing to be aborted in the final minutes before the touchdown.

You try fitting a rhino into a VW and hoping he knows how to drive when the Abort discrete is set (nevermind 1200-group alarms)!

Buzz And Neil Are Lucky To Have Made It

Fucking coders, man:

The code and its comments has lots of injokes: an injunction to the astronaut to "crank the silly thing around"; a file called "PINBALL_GAME_BUTTONS_AND_LIGHTS.s"; a subroutine called "BURN_BABY_BURN--MASTER_IGNITION_ROUTINE.agc" and a comment about "TRASHY LITTLE SUBROUTINES" -- and, of course, some Shakespeare ("IT WILL BE PROVED TO THY FACE THAT THOU HAST MEN ABOUT THEE THAT/USUALLY TALK OF A NOUN AND A VERB, AND SUCH ABOMINABLE WORDS AS NO/CHRISTIAN EAR CAN ENDURE TO HEAR.").

The Github community is going at the code with humorous gusto.

Now that the code is on GitHub, programmers can actually suggest changes and file issues. And, of course, they have. One developer submitted an issue saying, “A customer has had a fairly serious problem with stirring the cryogenic tanks with a circuit fault present,” and listed steps to reproduce the problem. “Be aware that this may be hazardous to the tester attempting it,” he added. The responses flooded in.

I actually really appreciate all that since I used to call my shit all sorts of weird names.  But I was a bad programmer and never commented a damned thing, so I usually couldn't figure out what the hell I'd done later.  This is why I do networking and not coding these days...

One Small Step

The Hindu:

Taking baby steps towards developing a reusable launch vehicle capable of sending spacecraft into orbit and returning to the earth’s surface, the Indian Space Research Organisation on Monday successfully tested the country’s first winged-body aerospace vehicle.

The technology, when developed completely, would launch spacecraft, including satellites, into space and re-enter the earth’s atmosphere withstanding extreme pressure and heat conditions and land in an intended spot, helping to cut costs on launch vehicles substantially.

“We had three objectives for Monday’s launch: To test the characterisation of the aero-thermo dynamics of hypersonic flights; to test the autonomous mission management of hypersonic vehicles; and to test the necessary re-entry technology for the vehicles,” K. Sivan, Director of the Thiruvananthapuram-based Vikram Sarabhai Space Centre, said.

A booster rocket, carrying a winged-body aerospace vehicle (RLV-TD), took off from the spaceport at Sriharikota, some 100 km from Chennai, at 7 a.m. It climbed for about 90 seconds before its burnout. Coasting to an altitude of 56 km, where it was separated from the booster, RLV-TD inclined further to 65 km, an ISRO release said. From an altitude of 65 km, the vehicle made a re-entry into the earth’s atmosphere at Mach 5 (five times the speed of sound) and steered by its navigation, guidance and control system for safe descent, it glided down to the defined landing spot in the Bay of Bengal, 450 km from Sriharikota.

The total flight duration was about 12.8 minutes.

Dunno if I'd really call it baby steps.  Saw a commenter yesterday on a video about Apollo 10 questioning why they didn't just land then when the LM was so close to the surface.  Because you test the shit out of this stuff, even the little things.  Testing is good.  Every step is big.

“Get naked, allow an hour, have plenty of tissues handy…”

Boingboing:

Ariel Waldman, creator of Spacehack, has just published a delightful book titled "What's It Like in Space? Stories from Astronauts Who'Ve Been There?" Illustrated by Brian Standeford, it's a fun collection of astronaut anecdotes on everything from sneezing and farting in zero gravity to weird frights and the necessity of Sriracha in space. Here's an excerpt:

While performing a spacewalk is an exciting experience, it is also a very serious operation that is meticulously scripted for astronauts. The only time astronauts might get a chance to look around at where they are is when there’s a glitch in equipment and they get a few spare minutes while someone makes a repair. Astronaut Chris Hadfield found an opportunity to look around during one of his spacewalks:

“The contrast of your body and your mind inside . . . essentially a one-person spaceship, which is your space suit, where you’re holding on for dear life to the shuttle or the station with one hand, and you are inexplicably in between what is just a pouring glory of the world roaring by, silently next to you—just the kaleidoscope of it, it takes up your whole mind. It’s like the most beautiful thing you’ve ever seen just screaming at you on the right side, and when you look left, it’s the whole bottomless black of the universe and it goes in all directions. It’s like a huge yawning endlessness on your left side and you’re in between those two things and trying to rationalize it to yourself and trying to get some work done.”

Sneezing, farting...what about pooping?

PS--Rusty Schweikart knows from EVAs and glitches.  And, I suspect, pooping.
