CHAPTER 7: COUNTDOWN





7.1
INTRODUCTION

Keep careful track of time and the positions of the ships and moons. Two days after the monolith disappears, Jupiter explodes. Whether or not the characters escape depends on how quickly they link the Leonov and Discovery together and launch.
   After the monolith disappears, Tanya is easily convinced to leave the Jupiter system ahead of schedule. Any American who attempts to persuade her succeeds. If none of the Americans make an attempt, Tanya suggests joining the ships together. The following section, Linking the Leonov and Discovery, describes the linking procedure.
   Thirty hours after the monolith disap- pears, a spot appears on Jupiter. Use sec- tion 7.3, Jupiter's Black Spot, at that time.
   Throughout the linking procedure, Dr. Mikolai Ternovsky, the Leonov's navigator, will be plotting a course back to Earth. Sec- tion 7.4, Escape Course, explains the course the ships must follow.

7.2
LINKING THE LEONOV AND DISCOVERY

Linking the Leonov and Discovery is a tricky and difficult task. There are two steps to this maneuver, the approach and the hookup. First the ships must move toward each other very slowly and carefully - this is the approach step. Then, the ships must stay motionless relative to each other while the Leonov's clamp securely grips the Discovery - this is the hookup step. Each step is explained below.

THE APPROACH

Dr. Chandra must load and run HAL's dock- ing program. Dr. Chandra has an 80% chance to do this successfully. Then, HAL will pilot the Discovery toward the Leonov.
   Dr. Floyd must watch the Leonov and give HAL information to keep the ships aligned. Dr. Floyd has a 75% chance of doing this correctly.
   Curnow should prepare to go out into space to repair the ships if they collide and

are damaged. Max is on the Leonov, in his spacesuit, also ready to make repairs.
   Tanya is piloting the Leonov toward the Discovery. She must use her piloting skill (increase maneuver rating) to keep the Leonov aligned with the Discovery.
   The approach takes ½ hour. If everyone's dice roll is successful, the approach works; the two ships gently float together. If the approach works, proceed to the contact step below.
   If anyone's dice roll fails, the ships are not aligned and may collide dangerously. Read the following boxed text.


The Leonov, visible through the flight deck windows, begins to twist. Over the radio, Tanya says, "We are not aligned, repeat, we are not aligned. Terminate the approach sequence."

Both ships must stop to avoid colliding. If any PC halts the approach (or asks HAL to), both ships separate safely. Then the ships must back away and start the approach again.

THE HOOKUP

Dr. Chandra, Dr. Floyd, and Tanya must all make their checks again to keep the ships together while the clamp is secured to the Discovery.
   If everyone's check is successful, the clamp tightens onto the Discovery. If any- one's check fails, the ships move just as the slamp tightens. The clamp tears the Discov- ery's hull, and the ships drift apart. Curnow and Macx must both spend one hour to repair the damage. Then the ships must start the approach again. Read the follow- ing boxed text.

Over the radio, Tanya says calmly, "We are beginning to secure the clamp." Sud-

(boxed text continues)

denly, the ship shudders. A screech of tearing metal echoes through the ship. HAL says, "I just lost contact with the engines; a control trunk was severed. I have switched to a different control trunk, but the hull damage must be repaired before we can attempt to link the ships again."

After the first time the clamp is tightened, read the following boxed text.

After the clamp is secured, HAL speaks. "The clamp is not exerting even pressure. The forward edge is exerting 5% more pressure than the rear edge. There is a 40% possibility that the link will fail during the launch."

Although it is tightened, the clamp is slightly misaligned. There is a 40% chance that it will slip off under the stress of the launch.
   If the crew decides to align the clamp, Curnow and Max must spend 1 hour work- ing on the clamp. They both have an 80% chance of aligning the clamp. If either one is successful, the slamp is fixed and will not slip off accidently. If both Curnow and Max fail their rolls, the clamp slips off, and the ships drift apart. The crew must start the approach again.
   If the crew decides not to align the clamp, there is still a 60% chance that the clamp will hold through the launch in chapter 8.

7.3
JUPITER'S BLACK SPOT

Thirty hours after the monolith disappears, a black spot appears on Jupiter. The spot is growing noticeably larger every hour. If the characters are watching Jupiter closely, they notice the spot as soon as it appears. Astronomers on Earth notice the spot a few hours after it appears. Six hours after it appears, Mission Control asks the crew to investigate the spot using equipment aboard the Leonov and Discovery.
   Astronomers can perform experiments to try to learn what the black spot is. Below
