"Houston, we have checkmate"
From the NASA ISS report of August 13 2008
For more than a thousand years, the game of chess and its predecessors have
been played on park tables, in homes, at schools and, in modern times, even
on television and in arenas as a spectator sport.
But chess has now taken the next giant leap in a match that pits space against
Earth. NASA astronaut and chess aficionado Greg Chamitoff, speeding around the
Earth at five miles a second aboard the International Space Station, is in the
midst of a chess game with mission control centers. Unfortunately for the ground,
failure may be an option in this case: As the game enters its final stages,
Chamitoff appears to be winning.
Chamitoff brought a chessboard with him to the orbital complex on the space
shuttle in June. Aboard the station, he is supported by control centers at sites
around the world – including Houston, Moscow, Japan and Germany. The centers
take turns making moves against Chamitoff. Each center maintains a chess board
showing the game's status. Chamitoff introduced the Earth vs. space chess match
in a daily tag-up held with control centers to address questions regarding the
“Greg really has achieved his goal by getting us to realize that we can't
beat him as a team unless we work together,” said Heather Rarick, the
lead flight director for Expedition 17. “This competition with the crew
has been well received. The competition is definitely good for the team since
we work together using skills we otherwise wouldn't get to share, we learn more
about each other as well as the crew.”
An interview with America’s chess-playing astronaut
This "interview" was conducted by Harvey Lerman of the Florida
Chess Association, sending one e-mail message containing all the questions to
a Flight Director of the International Space Station (ISS). After approval,
the email was sent on to Gregory Chamitoff, who is currently America’s
astronaut on board the ISS. The questions were then answered by him in one email
which was forwarded to us for publication.
Harvey Lerman: How are you playing the game... on an
electronic screen? or with a magnetic set? I'd hate to see the pieces start
floating around the station. Who had the idea of playing chess in space ...
how did it come about and how did the chess set make the trip? Is it yours
or did someone have one made for the trip?
Greg Chamitoff: I'm playing on a board that I brought up with
me. I've been thinking about this ever since Expedition 6. I was a crew support
astronaut for that crew and worked as Capcom. One of the crew and I shared an
interest in chess. I suggested that we play 'over the loops', but it never worked
out. Ever since then I thought it would be a fun thing to do when (and if) I
got to fly on the Station.

I was looking for the perfect chess set for Space. It needed to be large enough
to be easily visible on a video camera view that the ground would normally be
using. The pieces would have to stick to the board very reliably, and it had
to be ultra lightweight because our personal allocation of 'stuff' that we can
bring is extremely limited. I eventually found the perfect chess set. It had
magnetic pieces and a felt board with a flexible metallic inner sheet. On the
ground, you could literally set up the board and then pick it up by a corner
and carry it off without anything falling off. Unfortunately, though, I eventually
found out that our NASA safety experts don't want us to bring anything magnetic
onboard, because of the potential that it could interfere with the operation
of onboard systems. So I ended up doing things the NASA way, which, of course,
means velcro! I'm using the same board from that original set, and
I bought an additional set with cheap hollow plastic pieces that were just the
right size. On the positive side, this chess set was even lighter than the original.
Once onboard, I spent one late weekend night cutting velcro circles to fit on
the pieces. Fortunately, the felt on the board works great as the other side
for the velcro. I haven't totally lost a piece yet, but one of the rooks did
escape for about 24 hours. I found it at one of the air-flow return filters
in the US Laboratory.
Do you normally play much chess when on Earth? Where do you live and
do you participate in any local chess club when on Earth?
I played chess all the time when I was younger. My father taught me how to
play when I was very young, and he always joked that he couldn't beat me after
I turned four. How old I actually was when I learned, and how many years he
let me win, I'll never know, but he encouraged me a great deal and played with
me endlessly when I was a kid. I played chess in school, started a few chess
clubs, and won several small tournaments when I was a kid. Once or twice I played
in official tournaments, but never took it that seriously. In recent times (like
the last decade), it seems that I rarely get a chance to play chess with anyone,
although I have a few times. I've enjoyed teaching some of the younger members
of my family, and children of friends, how to play, and encouraged them in the
same way my father did for me.

I do play chess occasionally against my computer or even my phone. I have a
chess program on my phone that usually wins – it's humiliating to think that
you can't beat your own phone at chess.
Are others in the crew helping you or do you play alone? What do they
think about it?
Well, we are officially playing as "Crew vs. Ground", so that's the
plan. They are kibitzing here and there, and keeping a close eye on the game.
I hear your opponents may be using the help of a grandmaster. Are you
hoping to have a Cosmonaut get a Russian GM to help you?

The fun of this is that we're playing 'Crew vs. Ground', although we've really
handicapped the ground quite significantly by making the different control centers
take turns with their moves. They are not supposed to interact between control
centers to discuss their strategy, and so this makes it an additional challenge
for the ground. Hopefully this evens the odds a bit!
Do you take a while to plan your move, or do you just come up with it
while "on the john"? Do you have any chess books or other material
to help you decide on the move? Do your other duties get in the way of playing
I'm taking a day or more between moves, so I have plenty of time to stare at
the board. I'm usually too busy during the day to think much about it, so I
tend to think about my move in the evening. The only problem with taking so
long between moves is that there is now some pressure to make sure it's not
a stupid move. In fact, this game has kept me up quite late on several occasions,
but I'm enjoying it very much. We do have software games on-orbit, including
chess, and I've spent some time playing games against the computer as well.
Can we get a photo of you... playing chess... especially while making
the winning move?
I'll be happy to do that – it's a good idea for my own scrapbook too.

Do you have some sort of wager on the game? What prize do you get for
winning? I know the chess world would be thrilled to read about your story.
There are no wagers of any kind, this is just for fun. I guess we'll have to
see how this evolves for game number two and beyond. It would be fun to play
simultaneous games from here. The Control Center in Moscow said that they would
rather make all of their own moves (naturally)! I don't know if I could get
any sleep if I tried to play six simultaneous games, but why not – it
could be fun to do that. Someone in Houston (I would like to know who) came
up with an Excel spreadsheet to track the game. It's great – it has all
the moves listed, but also has a graphical representation of the board. If we
start playing multiple games, we could use this to keep track of them all.

I just saw the position after your 16th move and think you're "putting
it" to them with that one! How do you think the game has proceeded so
I think I got very lucky with one small move early on – that was P-QR4.
It's made it possible for me to eventually corner black's queen. I've traded
a lot of material for that queen, though, and it's not clear how much of an
advantage it will turn out to be. But at the moment I'm optimistic.
I just read in the paper that they "retreat you into the Soyuz for
the entire space walks in case of an emergency". Is that so you can concentrate
on the chess game in case the ground makes a surprising move?
I did spend a lot of time crammed into the Soyuz descent capsule during the
two recent Russian spacewalks. Each time it was about eleven hours, and I now
know for sure that I'm not completely claustrophobic. The reason for this was
to make sure that the three of us stayed on the same side of a module at vacuum
in the event that there was a problem repressurizing after the EVA [Extra Vehicular
Activity; i.e., spacewalk]. With the Soyuz parked in its current location, the
EVA hatch is between the main Station modules and our rescue vehicle (the Soyuz).
We have a rule that basically assures that the crew is never separated from
the rescue vehicle (and certainly not by having a module at vacuum in the path).
So in the case of some problem during the EVA, my crew-mates would have entered
the upper part of the Soyuz vehicle and repressurized there before doffing their
suits. In that case, we would either have to undock and redock the Soyuz to
a different port on the Station, or return to Earth, depending on the nature
of the problem.
As such, I also had a lot of extra equipment in there with me to handle a variety
of off-nominal situations. Although there would normally be three people in
there for a descent, it was quite full with just one person, three suits, and
all the extra gear I had. Admittedly, though, some of that gear was to keep
me busy – a computer, extra batteries, a book, a camera, food, water,
extra clothing (it gets cold in there), etc. I didn't play any chess in there,
but I did write some letters, listened to music, and I watched a ton of Star
Trek and StarGate I. For the second time around, I basically did a Star Trek
Enterprise marathon! I'm watching the whole Enterprise series from beginning
to end – usually one episode a day while I'm on our stationary cycling
machine. It was a little strange to be watching Sci-Fi while looking out the
Soyuz window down on the Earth. For all my life it seemed like hopeful fiction,
but here I was sitting in a real spacecraft flying high above a beautiful planet.

I feel so fortunate to live at a time when we are beginning our exploration
of Space, and to have a chance to be part of it. We might not have warp drive
and transporters, but there's no denying that we have a permanent off-world
presence on an amazing, huge, and very capable International Space Station up
here, and that, in the future, people will be living and working on all kinds
of space facilities to explore and expand humanity beyond Earth. From right
here it seems like such a small and reachable step to just go farther.
Please tell us about your some of your duties on this space mission and
its main goals.
I arrived on the Shuttle STS-124 mission, which was primarily aimed at installing
the new Japanese Experiment Module (JEM), also named 'Kibo' (meaning Hope).
This module is a huge addition to the Space Station and a state-of-the-art,
very capable space laboratory. One of my primary objectives on the ISS Expedition
17 mission is to check out all systems in the JEM and bring the scientific equipment
online to begin the Japanese program of scientific research. The European Columbus
module is also a recently added advanced laboratory and there are numerous investigations
planned there as well. Between the U.S., European, and Japanese programs, I've
got a very busy six months up here trying to accomplish as much science as we
possibly can, while also preparing the Station for a transition to a six-person
crew. In November, the STS-126 Shuttle mission will bring additional life support
equipment, and the work required to reconfigure the Station to support the larger
long-duration crews of the future begins now.
If you win would you claim to be the chess champion of space? What are
your opinions of other intelligent life in the universe that may offer a challenge
to your title?
I hope that the 'handicap' we gave to the Control Centers will assure that
no one can take sole blame or credit for however this game turns out. We're
playing for the fun of it, and for the camaraderie and team spirit that I hope
it generates between centers on the ground and with us onboard. I haven't seen
any aliens out here that can play chess, but I keep looking!

Chamitoff is now playing new games, six in all, simultaneously, one against
each of the Ground Stations. You can follow the game against the control
team in Houston. Each time the ground and Chamitoff makes a move, usually
one each day, the NASA Web will provide a graphic
update [PDF] of the move and the current state of the board below.
The move that is made will be updated at about 4 p.m. CDT on weekdays.
Weekend moves will be updated on the following Monday.
