“Jet lag,” muttered one of his friends, “long trip from California. Really mucks you up for a couple of days.”
“I don’t think he’s been there at all,” muttered another. “I wonder where he has been. And what’s happened to him.”
~Douglas Adams, So Long and Thanks for All the Fish
In our blog anniversary post (click HERE for that one), we tried to make a sort of sense of what we’ve been doing over the past year. That was on July 1, before we headed off to the Space Coast for the last-ever space shuttle launch. This past week has been an intense physical and emotional experience in which we’ve lost track of time. We’re settling back into our regular routines; Anna went to the dry cleaner and the grocery store; Doug returned to his daily job at the library. But our attention remains on STS-135 too.
Atlantis and the International Space Station are now orbiting our planet at roughly 17,500 miles an hour. That means the astronauts experience a sunrise and sunset every hour-and-a-half or so, making for more than 15 shuttle space days for every Earth day, if we define a day by sunrise. But shuttle astronauts in space don’t mark time that way. Instead, their clock (and that big countdown clock you saw on NASA-TV and CNN last Friday) ticks off mission elapsed time (MET). At twenty-four hours MET, Flight Day 2 begins.
At the beginning of each flight day, the astronauts are awakened with a song from Earth. Music marks time for them in a less precise, more culturally inflected way than MET. On Flight Day 2, that wake-up song was “Viva la Vida” by Coldplay, picked by Pilot Doug Hurley. Coldplay has awakened shuttle astronauts three times before.
For Flight Day 3, Commander Chris Ferguson chose “Mr. Blue Sky” by Electric Light Orchestra. It’s the fourth time E.L.O. has awakened a shuttle crew.
And what did Mission Specialist and native Illinoisan Sandy Magnus choose for Flight Day 4? “Tubthumping” by Chumbawamba. I get knocked down. But I get up again. You’re never going to keep me down. Not a bad message for NASA right now.
Flight Day 5 started with “More” by Matthew West, chosen by Mission Specialist Rex Walheim.
On Flight Day 6, Elton John offered a special message for the STS-135 crew. “Rocket Man” woke up this crew and the crews of four previous shuttle crews.
As part of his message to STS-135 on Flight Day 7, Michael Stipe said, “I recorded ‘Man on The Moon’ for NASA in Venice, Italy, where Galileo first presented to the Venetian government his eight-power telescope, and in 1610 wrote ‘The Starry Messenger’ (Sidereus Nuncius), an account of his early astronomical discoveries that altered forever our view of our place in the universe.” R.E.M.’s “Happy Shiny People” has awakened two previous shuttle crews.
“Good Day Sunshine” by Paul McCartney, with a cheery message from the former Beatle, roused the crew on Flight Day 8 at 12:59a.m. EDT today, on Friday, July 15. They had a bit of a computer problem at the beginning of their sleep shift, so NASA let the astronauts sleep a half-hour later than the planned schedule. They are in the midst of transferring the payload to the ISS, and they talked with President Obama and reporters today.
These last few days back home in California, we wish that our time was as organized as that of astronauts in orbit. The odd hours we’ve kept this last week in Florida and the day of travel on Tuesday, with the three-hour time change, have left our heads spinning. We’re coming off that odd mix of exhaustion and adrenaline, feeling sleepy and alert simultaneously, but starting to get back on track with things we’d put aside and shored up.
What might it mean to measure time according to our missions, with a version of MET? The mission clock would begin at zero and elapse as we (presumably) made progress on the project over time. Blog elapsed time: +379 days. Novel elapsed time: +5 years, if we include research and breaks for moving and other writing projects. Or perhaps, the clock should stop when we are working on another project, like a hold in the countdown clock before launch. Though they have a multitude of tasks, the astronauts are focused on a single mission; they can’t stop the MET clock while they draft a short story because they can’t interrupt the mission tasks for other ideas that come to mind. If something is scheduled for +4 days, it must occur on the fourth day of the mission whether the shuttle’s mission begins on its originally scheduled launch date or, after a delay, two days or two months later.
On the Earth’s surface, we move among several projects at a time. We write a blog while holding down day jobs. We write articles together and separately and have larger writing projects too. Just as it would quickly become silly for orbiting astronauts to count days by each sunrise they view, those of us under the great influence of gravity cannot keep accurate track using mission elapsed time. The way a person measures time must fit the circumstances, while also making sense with the way the larger world works.
It turns out that the shuttle astronauts are not beholden only to MET. They are moving between MET and the coordinated universal time (UTC) of the International Space Station (ISS). UTC is a carefully devised standard time, a more precise replacement for Greenwich Mean Time (GMT), with even leap seconds added to sync up UTC with the Earth’s rotation. The second (and millisecond) are constant, but larger units can vary in order to keep universal time accurate. Computers also use UTC. Because the ISS is an ongoing project, a destination for many individual shuttle missions over the years, using an MET clock would run up days into meaningless numbers. Elapsed time isn’t that important to know on the ISS. The unload the shuttle payload when it gets there, not according to some schedule the ISS itself has. So that the STS-135 crew can move between the shuttle and ISS time zones without getting too confused, the space shuttle has a UTC clock too.
Music provides yet another way to mark time, both as a daily wake-up demarcation and in a larger sense. Songs stick with us. Admit it, you thumped to Chumbawamba in the fall of 1997. How old were you when E.L.O. was churning out the hits in the 1970s? Ah, “Rocket Man” and 1972: the Vietnam War, the Watergate scandal, The Price is Right begins and Bewitched ends. Apollo 16 and Apollo 17 conclude U.S. manned spaceflight (or so it seemed at the time).
As Daniel Levitin puts it in This Is Your Brain on Music, “The story of your brain on music is the story of an exquisite orchestration of brain regions, involving both the oldest and newest parts of the human brain, and regions as far apart as the cerebellum in the back of the head and the frontal lobes just behind your eyes. It involves a precision choreography of neurochemical release and uptake between logical prediction systems and emotional reward systems. When we love a piece of music, it reminds us of other music we have heard, and it activates memory traces of emotional times in our lives.”
He goes on to explain why you may have a particular affinity for “Rocket Man” or “Tubthumping.” “Researchers point to the teen years as the turning point for musical preferences. It is around the age of ten or eleven that most children take on music as a real interest, even those children who didn’t express such an interest in music earlier. As adults, the music we tend to be nostalgic for, the music that feels like it is ‘our’ music, corresponds to the music we heard during these years. [...] Part of the reason we remember songs from our teenage years is because those years were times of self-discovery, and as a consequence, they were emotionally charged; in general, we tend to remember things that have an emotional component because our amygdala and neurotransmitters act in concert [hah, a pun!] to ‘tag’ the memories as something important.”
Chris Ferguson was 16 years old, that emotionally charged time of self-discovery, when “Mr. Blue Sky” was released in 1978. In 1997, when Chumbawamba hit the charts, Sandy Magnus had recently been selected for astronaut training and began her work at Johnson Space Center that led to her first shuttle mission in 2002. Nothing in Rex Walheim’s official NASA biography indicates why 2004, when “More” was released, might have been a particularly emotionally charged time for him, but that song was the most-played song on Christian radio that year. In 2008, when Coldplay released “Viva la Vida,” Doug Hurley was training for his first space shuttle mission.
At breakfast at the Village Inn in Titusville, this past week, we heard “Reunited” by Peaches & Herb, a song we hadn’t heard in years, a song that was on the K-tel record that Anna received at her boy–girl birthday party in eighth grade.
On one of our previous trips to the Space Coast, the radio in our rental car had been left set to FM 96.5 when we picked it up. This station plays a mix of classic rock that we don’t listen to much anymore, but it replicates the playlist of 97X, the radio station from Moline, Illinois, of Doug’s teen years. (As a curious aside, Doug’s high school locker number was 97. Each fall for the four years that Doug attended AHS, an “X” mysteriously appeared next to the locker number, making his locker 97X.) The Orlando station’s signal is strong, the songs familiar fodder for our NASA-visit mode.
Great White’s “Once Bitten Twice Shy,” the 1989 cover of a 1975 Ian Hunter song (Ian was a founding member of Mott the Hoople, a name that has the feel of a Douglas Adams novel), was in heavy rotation this past week. After not hearing that song for more than two decades, we probably heard the ode to groupies and casual sex every day last week. For Doug, “Once Bitten Twice Shy” calls to mind the summer of 1989, when he studied Russian at Beloit College. The song and that moment in time that it recalls link together several of the themes that we’ve been exploring. Who’d have predicted from the vantage of that late-1980s summer, still several months before the fall of the Berlin Wall and more than two years before the end of the Soviet Union, that today Russian would be an official language on the space station (all U.S. astronauts who serve extended periods on the ISS speak Russian) and that the United States will require Soyuz rockets to carry astronauts into low-earth orbit?
