Boarding Party
Even in the best of circumstances, it is not easy to board a
derelict and uncooperative spaceship. Indeed, it can be posi-
tively dangerous.
Walter Curnow knew that as an abstract principle; but he
did not really feel it in his bones until he saw the entire
hundred-metre length of Discovery turning end-over-end.
while Leonov, kept at a safe distance. Years ago, friction had
braked the spin of Discovery's carousel, thus transferring its
angular momentum to the rest of the structure. Now, like a
drum-majorette's baton at the height of its trajectory, the
abandoned ship was slowly tumbling along its orbit.
The first problem was to stop that spin, which made
Discovery not only uncontrollable but almost un-
approachable. As he suited up in the airlock with Max
Brailovsky, Curnow had a very rare sensation of incom-
petence, even inferiority; it was not his line of business. He
had already explained gloomily, `I'm a space engineer, not a
space monkey'; but the job had to be done. He alone pos-
sessed the skills that could save Discovery from Io's grasp.
Max and his colleagues, working with unfamiliar circuit dia-
grams and equipment, would take far too long. By the time
they had restored power to the ship and mastered its con-
trols, it would have plunged into the sulphurous firepits
below.
`You're not scared, are you? asked Max, when they were
about to put on their helmets.
`Not enough to make a mess in my suit. Otherwise, yes.'
Max chuckled. `I'd say that's about right for this job. But
don't worry-I'll get you there in one piece, with my-what
do you call it?'
`Broomstick. Because witches are supposed to ride
them.'
`Oh yes. Have you ever used one?'
`I tried once, but mine got away from me. Everyone else
thought it was very funny.'
There are some professions which have evolved unique
and characteristic tools - the longshoreman's hook, the
potter's wheel, the bricklayer's trowel, the geologist's ham-
mer. The men who had to spend much of their time on
zero-gravity construction projects had developed the
broomstick.
It was very simple-a hollow tube just a metre long, with
a footpad at one end and a retaining loop at the other. At the
touch of a button, it could telescope out to five or six times
its normal length, and the internal shock-absorbing system
allowed a skilled operator to perform the most amazing
manoeuvres. The footpad could also become a claw or hook
if necessary; there were many other refinements, but that
was the basic design. It looked deceptively easy to use; it
wasn't.
The airlock pumps finished recycling; the EXIT sign
came on; the outer doors opened, and they drifted slowly
into the void.
Discovery was windmilling about two hundred metres
away, following them in orbit around Io, which filled half
the sky. Jupiter was invisible, on the other side of the
satellite. This was a matter of deliberate choice; they were
using Io as a shield to protect them from the energies raging
back and forth in the flux-tube that linked the two worlds.
Even so, the radiation level was dangerously high; they had
less than fifteen minutes before they must get back to shel-
ter.
Almost immediately, Curnow had a problem with his
suit. `It fitted me when I left Earth,' he complained `But
now I'm rattling around inside like a pea in a pod.'
`That's perfectly normal, Walter,' said Surgeon-
Commander Rudenko, breaking into the radio circuit.
`You lost ten kilos in hibernation, which you could very
well afford to miss. And you've already put three of them
back.'
Before Curnow had time to think of a suitable retort, he
found himself gently but firmly jerked away from Leonov.
`Just relax, Walter,' said Brailovsky. `Don't use your
thrusters, even if you start tumbling. Let me do all the
work.'
Curnow could see the faint puffs from the younger man's
backpack, as its tiny jets drove them toward Discovery. With
each little cloud of vapour there came a gentle tug on the
towline, and he would start moving toward Brailovsky; but
he never caught up with him before the next puff came.
He felt rather like a yo-yo - now making one of its
periodic comebacks on Earth - bouncing up and down
on its string.
There was only one safe way to approach the derelict, and
that was along the axis around which it was slowly revolv-
ing. Discovery's centre of rotation was approximately
amidships, near the main antenna complex, and Brailovsky
was heading directly toward this area, with his anxious
partner in tow. How will he stop both of us in time?
Curnow asked himself.
Discovery was now a huge, slender dumbbell slowly flail-
ing the entire sky ahead of them. Though it took several
minutes to complete one revolution, the far ends were
moving at an impressive speed. Curnow tried to ignore
them, and concentrated on the approaching - and immobile
- centre.
`I'm aiming for that,' said Brailovsky. `Don't try to help,
and don't be surprised at anything that happens.'
Now, what does he mean by that? Curnow asked himself,
while preparing to be as unsurprised as possible.
Everything happened in about five seconds. Brailovsky
triggered his broomstick, so that it telescoped out to its full
length of four metres and made contact with the
approaching ship. The broomstick started to collapse, its
internal spring absorbing Brailovsky's considerable
momentum; but it did not, as Curnow had fully expected,
bring him to rest beside the antenna mount. it immediately
expanded again, reversing the Russian's velocity so that he
was, in effect, reflected away from Discovery just as rapidly
as he had approached. He flashed past Curnow, heading out
into space again, only a few centimetres away. The startled
American just had time to glimpse a large grin before
Brailovsky shot past him
A second later, there was a jerk on the line connecting
them, and a quick surge of deceleration as they shared
momentum. Their opposing velocities had been neatly can-
celled; they were virtually at rest with respect to Discovery
Curnow had merely to reach out to the nearest handhold,
and drag them both in.
`Have you ever tried Russian roulette?' he asked, when he
had got his breath back.
`No - what is it?'
`I must teach you sometime. It's almost as good as this for
curing boredom.'
`I hope you're not suggesting, Walter, that Max would do
anything dangerous?'
Dr Rudenko sounded as if she was genuinely shocked,
and Curnow decided it was best not to answer; sometimes
the Russians did not understand his peculiar sense of
humour. `You could have fooled me, 'he muttered under his
breath, not loud enough for her to hear.
Now that they were firmly attached to the hub of the
windmilling ship, he was no longer conscious of its rotation
- especially when he fixed his gaze upon the metal plates
immediately before his eyes. The ladder stretching away
into the distance, running along the slender cylinder that
was Discovery's main structure, was his next objective. The
spherical command module at its far end seemed several
light-years away, though he knew perfectly well that the
distance was only fifty metres.
`I'll go first,' said Brailovsky, reeling in the slack on the
line linking them together. `Remember - it's downhill all
the way from here. But that's no problem - you can hold on
with one hand. Even at the bottom, gravity's only about a
tenth gee. And that's - what do you say? - chickenshit.'
`I think you mean chickenfeed. And if it's all the
same to you, I'm going feet first. I never liked crawling
down ladders the wrong way up - even m fractional
gravity.'
It was essential, Curnow was very well aware, to keep up
this gently bantering tone; otherwise he would be simply
overwhelmed by the mystery and danger of the situation.
There he was, almost a billion kilometres from home, about
to enter the most famous derelict in the entire history of
space exploration; a media reporter had once called Discov-
ery the Marie Celeste of space, and that was not a bad ana-
logy. But there was also much that made his situation
unique; even if he tried to ignore the nightmare moonscape
filling half the sky, there was a constant reminder of its
presence at hand. Every time he touched the rungs of the
ladder, his glove dislodged a thin mist of sulphur dust.
Brailovsky, of course, was quite correct; the rotational
gravity caused by the ship's end-over-end tumbling was
easily countered. As he grew used to it, Curnow even
welcomed the sense of direction it gave him.
And then, quite suddenly, they had reached the big,
discoloured sphere of Discovery's control and life-support
module. Only a few metres away was an emergency hatch -
the very one, Curnow realized, that Bowman had entered
for his final confrontation with Hal.
`Hope we can get in, muttered Brailovsky. `Pity to come
all this way and find the door locked.'
He scraped away the sulphur obscuring the AIRLOCK
STATUS display panel.
`Dead, of course. Shall I try the controls?'
`Won't do any harm - but nothing will happen.'
`You're right. Well, here goes with manual...'
It was fascinating to watch the narrow hairline open in the
curved wall, and to note the little puff of vapour dispersing
into space, carrying with it a scrap of paper. Was that some
vital message? They would never know; it spun away,
tumbling end over end without losing any of its initial spin
as it disappeared against the stars.
Brailovsky kept turning the manual control for what
seemed a very long time, before the dark, uninviting cave of
the airlock was completely open. Curnow had hoped that
the emergency lights, at least, might still be operating. No
such hick.
`You're boss now, Walter. Welcome to US territory.'
It certainly did not look very welcoming as he clambered
inside, flashing the beam of his helmet light around the
interior. As far as Curnow could tell, everything was in
good order. What else had he expected? he asked himself.
half angrily.
Closing the door manually took even longer than
opening it, but there was no alternative until the ship
was powered up again. Just before the hatch was sealed,
Curnow risked a glance at the insane panorama outside.
A flickering blue lake had opened up near the equator; he
was sure it had not been there a few hours earlier. Brilliant
yellow flares, the characteristic colour of glowing sodium,
were dancing along its edges; and the whole of the nightland
was veiled in the ghostly plasma discharge of one of Io's
almost continuous auroras.
It was the stuff of future nightmares - and as if that was
not sufficient, there was one further touch worthy of a mad
surrealist artist. Stabbing up into the black sky, apparently
emerging directly from the firepits of the burning moon,
was an immense, curving horn, such as a doomed bull-
fighter might have glimpsed in the final moment of truth.
The crescent of Jupiter was rising to greet Discovery and
Leonov as they swept toward it along their common orbit.
