Projects: Solar Sailing
The Story of Cosmos 1 is Not Over: A Personal Report
By Louis Friedman
June 25, 2005:
The word failure is sticking in my craw. Certainly, we failed
to achieve the objective of Cosmos 1: we did not achieve solar-sail
flight. But I don’t
think, with all we have done, that I can call Cosmos 1 a failure.
What’s so excruciatingly frustrating is that we were done in by a launch
vehicle failure. Our spacecraft never got a chance even to try. But we chose
to launch on the Volna, and we take responsibility for that.
People keep asking me how I feel. Because I first became involved with solar
sailing 30 years ago, they think that some dream of mine has now been destroyed.
But, I am not about dreams, nor technologies, no matter how sweet. Rather, I
want to make space missions happen, to shape the future – so you might
think that I should be even more “bummed out.” After all, solar sailing
is in our future; the Cosmos 1 mission is now in our past.
Surprisingly, I am not bummed out. I expected to be. Secretly, not sharing with
anyone, I thought that if this mission failed I would come back devastated and
in a mood to give it up. So, at about 20:25 GMT on 21 June when it became evident
that something had gone gravely wrong with the mission, I waited for the depression
to set in. Instead, I got caught up in the immediacy of the situation, and now,
four days afterward, I am more focused on what we did, what we still are doing,
and what we might do in the future than I am with regret about what might have
been.
I’ve now been involved with three missions that ended in Russian launch
failures: Mars 96 was failed by a Proton and our solar sail project suffered
two Volna failures. But this was the first launch failure that was evident in
real-time. After the 20-minute launch phase went by with just a single sentence
of report, when we were expecting nearly minute-by-minute updates, we knew something
must have gone wrong. The one sentence, coming two minutes after launch, was “Confirm
first-stage separation.” That report is now significant because a half-hour
or so later, Evgeniy Kulagin, the Flight Control Manager, came over and said
it was an error— first-stage separation never occurred. And later yet,
we learned that the Russian space agency (RKA), acting on information from the
Makeev Rocket Design Bureau (the Volna’s manufacturer), had issued a statement
saying that no stages separated and the whole launch vehicle, plus spacecraft,
flew on a much-shortened trajectory into the Barents Sea.
The issue of whether or not the Volna’s stages separated is the critical
one for resolving the differing reports about what happened to our spacecraft.
At first, we were also told that the portable tracking stations in Petropavlosk,
Kamchatka and Majuro in the Marshall Islands received no signals. That seemed
to be the end of it. Jim Cantrell reported from Project Operations Pasadena (POP)
that the US Strategic Command also saw nothing. But soon my colleague, Slava
Linkin of the Space Research Institute, the payload and electronics leader of
the project, reported that Oleg Andreyev (a member of his group at IKI who was
in charge of the portable station in Kamchatka) said that Doppler data (tracking
information about the speed and position of the spacecraft) was recorded in Kamchatka.
Then, as we were driving home at 4 am Moscow time, Jim Cantrell called me on
my cell phone from our POP room and said that Viktor Kerzhanovich had indeed
received a signal in Majuro – a very weak one that was not noticed on the
frequency meter, but was contained within the data recorded. When we called the
team at the Tarusa station, who were in charge of orbit tracking, they told us
that the Czechs at the Panska Ves station had also received a signal.
The mystery of the signals received from a spacecraft reported to be at the bottom
of the sea has occupied us since. The Russian military and space agency are firm
that the entire rocket and spacecraft went down together. But then, what were
those signals in the data recorders? They are now being analyzed by Dr. Linkin’s
group, the Czech tracking group, and The Planetary Society project operations
group. There seems to be some indication that the spacecraft was injected into
a low orbit, one that would quickly decay and cause the spacecraft to fall back
to Earth and burn up in the atmosphere. We hope to have more to say about that
within several days.
As we were planning our mission, we spent a lot of time thinking about the value
of creating an extra portable ground station and taking it to Majuro in the South
Pacific for only seven minutes of work during the first orbit. Working out the
logistics of a quick trip to the Marshall Islands was not easy. Later, we added
the Panska Ves tracking station in the Czech Republic to the project. Those decisions
turned out to be correct and valuable. So, too, was the effort made by Jim Cantrell
and his POP team, and Vladimir Nazarov and his MOM (Mission Operations Moscow)
team, to facilitate and enable rapid data handling in the mission. I would not
feel so comfortable with any conclusion we make if it weren’t both coordinated
and independently reviewed by these two teams.
There are a lot of acknowledgements to make and individuals to thank. We’ll
do that later. Right now, I do want to single out two of our team: Vladimir Gotlib
in Russia, who lost his wife to illness less than a month ago and suffered a
car accident on the way to a final test of tracking equipment at the Bear Lakes
station near Moscow; and Greg Delory of the University of California, Berkeley,
Space Science Laboratory who is getting married in August. They remind us how
much of our lives are invested in the work of creating a space mission, and how
that work affects our personal lives. Even when the mission is not accomplished,
they—and everyone involved—can take solace in the pride of what they
did and the value of their effort.
So right now, I am not thinking about what might have been. What we did is not
bad. We built the first solar-sail spacecraft. There is even a chance it got
to orbit in working condition and ready for its mission. We created an international
partnership with very limited resources. We conducted the first space mission
by a privately funded space-interest group. We tested the notion of private funding
for space ventures based on the idea that they have exciting stories to tell.
We built a private partnership with a science-based entertainment company, Cosmos
Studios – a partnership based on shared vision of the value of exploration.
We engaged national space agencies – notably NASA – won their respect,
and spurred on their programs in solar sailing. More than a simple “prize” adventure,
this may be a segue to private-public partnerships in pursuit of popular goals.
And we certainly captured the huge public interest in exploring space. The public
attention to this project was overwhelming – almost. The Planetary Society
staff is doing a great job of coping with it.
No way can I be depressed with all these achievements on our slate.
There are more specific technical accomplishments from Cosmos 1. The spacecraft
design offers great promise as a platform for future missions, including, perhaps,
even missions to Mars. The low-cost system we put together for mission operations,
tracking, data-handling, and international coordination of a satellite is a model
for the future
One other achievement is noteworthy: we did this mission entirely with private
funds. Ann Druyan and Cosmos Studios was an incredibly loyal sponsor, philanthropist
Peter Lewis and the members of the Planetary Society were very generous donors.
In its 25 years, The Planetary Society has been part of both failed and successful
space missions. Two examples come immediately to mind: Mars Polar Lander crashed
carrying our Mars Microphone. The hughly successful Mars Exploration Rovers carried
our calibration target and hosted our Red Rover Goes to Mars students. We know
well the highs and lows of space exploration.
We deeply appreciate and are buoyed by the determination and spirit of Planetary
Society members and by the public who wish us well, congratulate us for our
efforts, and are telling us even now, “Keep going.” We will keep
going. Although right now, I don’t know exactly how, I do know that we
are committed to trying again, for The Planetary Society exists to make space
exploration happen. Join us on this continuing adventure
