Technology: July 2009 Archives

I was five years old, but I got to stay up late to watch the moon walk. We were at my grandparents' house in Nowata. My grandpa sold and repaired TVs, radios, and appliances (Johnny's Electronics), so he had a color TV. (We wouldn't have one for a few years yet.) Not that color TV mattered -- the only picture was a ghostly black and white image of Neil Armstrong descending the ladder.

To this preschooler, the Apollo missions seemed like a regular TV series: Apollo 7 in October 1968, Apollo 8 at Christmas, Apollo 9 in March '69, Apollo 10 in May. (Of course, there was a NASA TV series -- I Dream of Jeannie -- and that space program seemed to have a mission every week.) I knew the names of the spaceships -- Gumdrop and Spider, Charlie Brown and Snoopy, Columbia and Eagle. The Gulf station at Washington and Frank Phillips Blvd gave away very intricate cardboard lunar module models -- the kind you put together with tab A and slot B. (We didn't know it at the time, but it's funny to think that the thin cereal-box cardboard was thicker than the LEM walls.) Like all five-year-old American boys in 1969, I wanted to be an astronaut when I grew up.

I've been reliving those eight days in July through a series of YouTube videos -- excerpts of ABC and NBC coverage of Apollo 11. While it's interesting to learn more about the behind the scenes, through newly released and restored film and interviews, it's been fun to experience the events and to share them with my children as most of us experienced them four decades ago. (Someone else posted the videos; I just created a playlist.)

The videos cover the launch, moon landing, moon walk, rendezvous, splashdown, and arrival on the USS Hornet. ABC used animations -- hand-inked cartoons -- and simulations -- guys in spacesuits in mockups of the CM and LEM -- to accompany mission audio and show what couldn't be shown by live video. Both ABC and NBC commentators left room for the astronauts and Houston to be heard. (I saw some of the CBS coverage on the History Channel; as others have observed, Cronkite didn't know when to be silent.)

Frank Reynolds anchored coverage for ABC, with science reporter Jules Bergman. The NBC coverage includes David Brinkley, Chet Huntley, and Frank McGee.

One of the excerpts has a long discourse by Huntley, with McGee chiming in, about priorities, about whether America's space program was just a series of bad decisions triggered by Sputnik. The two suggested that just as government had engineered a successful trip to the moon, government could fix hunger and homelessness if only the political will were there. (McGee said, "We have the technology -- the software and the hardware.") After watching this, my son and I had an interesting discussion on the fallacy behind the lament, "if we can put a man on the moon, why can't we solve complicated social problem X?"

Another segment has Frank Reynolds throwing it over to a very young Peter Jennings for a short ABC newscast with stories on Vietnam, Chappaquiddick, and a possible air traffic controller strike. The story on Vietnam was interesting -- the report insisted on referring to the Viet Cong as the "National Liberation Front," making it sound like an indigenous guerrilla movement rather than the arm of the Communist North Vietnamese government that it was.

In another segment, Rod Serling led a panel discussion on the moon landing with science fiction authors Frederick Pohl and Isaac Asimov, asking whether any of the authors had predicted a moon landing in their books.

An interesting historical note: After the moon landing and before the moon walk, Buzz Aldrin took communion on the moon in conjunction with his congregation (Webster, Tex., Presbyterian Church) back home, using bread and wine and a chalice provided by his pastor. In 2003, the Episcopal Church recognized the occasion by making July 20 a lesser feast day in the church calendar: "First Communion on the Moon."

Here is the collect for the feast:

Creator of the universe,
your dominion extends through the immensity of space:
guide and guard those who seek to fathom its mysteries [especially N.N.].
Save us from arrogance lest we forget that our achievements are grounded in you,
and, by the grace of your Holy Spirit,
protect our travels beyond the reaches of earth,
that we may glory ever more in the wonder of your creation:
through Jesus Christ, your Word, by whom all things came to be,
who with you and the Holy Spirit lives and reigns, one God, for ever and ever.
Amen.

The Rev. Mark Cooper, current pastor of Webster Presbyterian Church, tells more of the story:

At the time of the lunar landing Aldrin was an elder in our church. A communion kit was prepared for him by the church's pastor at the time, the Rev. Dean Woodruff. Since Presbyterians do not celebrate private communion, the communion on the moon was structured as part of a service with the congregation back at the church. Aldrin returned the chalice he used to earth. Webster Presbyterian continues to possess the chalice, which is now kept in a safety deposit box. Each year the congregation commemorates the lunar communion on the Sunday closest to the anniversary of the landing.

Finally, an excerpt from Charles Krauthammer's recent column, The Lunacy of Our Retreat from Space

Michael Crichton once wrote that if you told a physicist in 1899 that within a hundred years humankind would, among other wonders (nukes, commercial airlines), 'travel to the moon, and then lose interest . . . the physicist would almost certainly pronounce you mad.'... Fourteen months from today, for the first time since 1962, the United States will be incapable not just of sending a man to the moon but of sending anyone into Earth orbit. We'll be totally grounded. We'll have to beg a ride from the Russians or perhaps even the Chinese.... But look up from your BlackBerry one night. That is the moon. On it are exactly 12 sets of human footprints -- untouched, unchanged, abandoned. For the first time in history, the moon is not just a mystery and a muse, but a nightly rebuke.

MORE: How They Built it: The Software of Apollo 11:

The Apollo Guidance Computer (AGC) systems on each craft were designed and built by teams of researchers and students at the Massachusetts Institute of Technology (MIT), led by the late Dr. Charles Stark Draper, under contract with NASA. Garman was one of the many NASA workers who helped run, test and debug the fledgling MIT code that would run the Moon mission from launch to splashdown. Some dedicated hobbyists have even designed and built their own computers to replicate the original Apollo devices.

"The AGC was very slow, but very reliable and very small for that time in the history of digital computers," Garman said. "It was the earliest to use integrated circuits."

The software as it was designed was built basically from scratch by MIT, he said. How did they know what to start with? "MIT didn't really--they sort of made it up as they went along. Neither NASA nor MIT had built software for digital flight control and guidance systems in the past--no one had near this magnitude. So it took some soul-searching on both NASA and MIT's sides to write down requirements and create hard schedules and test plans."...

Jerry Bostick was 30 years old and was a member of Kranz's White Team for Apollo 11.

"I started out in the mission planning division, designing missions," he said. "We would write the requirements for all of the software in both the ground-based and the onboard computers, working primarily with MIT and IBM."

"We would give instructions to the programs by punching cards," Bostick said. "You had to wait at least 12 hours to see if it would work right." The early programming was done in the real-time computing complex in Houston using IBM 7094 computers with 64K of memory. There were no hard disks. All the data was stored on magnetic tape, with each computer having about eight tape drives. Most programs used for the mission were written in Fortran, Bostick said. "After Apollo 1, we upgraded to the biggest and the best equipment that government money could buy, the IBM 360 with an unheard of 1MB of memory. We went all the way from 64K to 1MB."

Thursday is the 40th anniversary of the launch of Apollo 11. A website called WeChooseTheMoon.org will be streaming the mission as it happened 40 years before. You can even follow the sequence of events on Twitter -- @AP11_SPACECRAFT and @AP11_CAPCOM.

I would love to watch and show my children some of the TV coverage from Apollo 11 -- Frank Reynolds and Jules Bergman on ABC, Frank McGee and John Chancellor on NBC, Walter Cronkite on CBS. If you know when any of that material is going to be aired or where it can be found on the web, please post a comment and let us all know.

I mentioned in passing that I spent more time than I intended last weekend trying to upgrade a PC to a bigger hard drive. The PC (a Dell Dimension 2400) doesn't have room for more than one hard drive, so I put the new drive in a USB enclosure and downloaded a copy of Clonezilla Live, an open-source disk cloning program that runs on a bootable Linux CD. The software itself was easy to use, but in trying to do a disk-to-disk clone, it would finish copying the data then fail on an fsync call at the very end. Next I tried the image backup method -- create a Clonezilla image of the old, smaller drive on a MyBook external hard drive, then restore that image to the new drive. After some trial and error, I downloaded another bootable Linux tool, gparted, to get the partitions right before restoring the image to the new drive. I then installed the new drive in the PC.

Result: The system booted, the data was all there, but Windows XP thought the disk was still the same old size. (40 GB instead of 400 GB.) Going into the Computer Management tool under Disk Management, I could see that the partitions were there and recognized as the correct size, but when I looked at Properties on the drive, it still showed 40 GB with very little free space.

Finally it occurred to me to look at the instructions that came in the box. Sure enough, the Seagate kit included a CD with cloning software from Acronis.

That didn't work either. The Seagate software, which was based on DR-DOS, could recognize the MyBook, but not the drive in the external enclosure. I then tried numerous ways to connect the second drive to the IDE controller, but cable lengths and connector locations defeated me. This box was simply not designed to have a second hard drive installed.

Last try: I downloaded an updated version of the Seagate DiscWizard software. This version, also by Acronis, was Linux-based, had no trouble recognizing the drive in the USB enclosure, and made it easy to partition and clone the disk. Windows XP now correctly recognizes the drive's full size.

So my weekend would have been much more productive if I'd read the instructions in the first place. Then again, since the Seagate CD in the box didn't work, I probably would have tried Clonezilla next, so in all likelihood I'd have tried all the same experiments, just in a different order.
