Summary: Petrov, and a team of
interstellar travelers, are suppose to leave on a voyage to a distant
planet in ten days. His trip will only take a few years, but those
few years will equate to 200 to 250 years on Earth. And that means
that by the time they return their friends, their loved ones, and
their home planet as they know it will be gone. It is especially
difficult for Petrov because he is leaving behind his wife. But such
is the price of interstellar travel. With the team gone, those left
behind grieve, yet only six months later they receive a notification
that the spaceship is returning. There is some speculation over
Petrov, the captain of the ship, being afraid and aborting the
mission. However, it is not the case as evident the moment everyone
sees the crew, or what was left of it. As we find out in the final
chapter, Petrov proposed an experiment to his crew, to which they
agreed, instead of traveling at a constant speed and having time slow
inside the spaceship, they would travel at constant acceleration
thereby possibly making the time pass faster inside the spaceship
relative to Earth. Their experiment succeeded, at the cost of lives
of two of their team members, and damage to their health after having
to live so long in gravity up to seven times that of Earth. There is
also a mention of Bikov and his ship whose departure was described in
a previous short story.
There are two
aspects of this story that I want to address. First, the idea that
those who are sent out to explore have to sacrifice not only their
lives but also their health, and that is on top of the sacrifices
they already had to make. Life at seven times the gravity that is on
Earth, is not easy, it is something that will effect their health for
the rest of their lives. But is that cost worth the reward of
returning to their home and their loved ones? Besides, should we
really put ourselves in the position where we tell others if they can
or cannot sacrifice themselves? Then again the previous story “Six
matchsticks” speaks to that aspect and at the time I had said that
sacrificing yourself is wasteful.
The second aspect
is the fairness of having sent other explorers out there when
ultimately their efforts are unneeded. Imagine if you send a ship to
a planet, the trip will take 20 years. But in 5 years a new engine
will be developed which will make the trip last only 5 years, and
that means the second crew will arrive before the first. And the
sacrifice of the first will be pointless, as their years will be
spent en route for no reason. Then again, perhaps if the first crew
never goes out then maybe that second faster engine never gets
developed.
