The Gentle Giants of Ganymede

minute, even under maximum acceleration, to intercept. Captain Hayter did not have time to juggle with arithmetic.

'Fire Ram One and engage,' he snapped.

A second later the reply came to confirm. 'Ram One fired. Locked on target.'

Beads of perspiration showed on some of the faces staring at the screens. The main display had not yet resolved the object, but one of the auxiliary screens displayed a plot of the two large vessels and a small but unmistakable blip beginning to close the gap between them.

'Radar reports steady approach speed of ninety feet per second.'

'Ram One closing. Impact at twenty-five seconds.'

Shannon licked his dry lips as he scanned the data on the screens and digested the flow of reports. Hayter had done the right thing and placed the safety of his ship above all other considerations. What to do now was a problem that lay solely with the mission director.

'Thirty miles. Fifteen seconds to impact.'

'Object holding course and speed steady.'

'That #146;s no missile,' Shannon said in a tone that was decisive and final. 'Captain, call off the interception.'

'Abort Ram One ,' Hayter ordered.

'Ram One disengaged and turning away.'

Long exhalations of breath and sudden relaxing of postures signaled the release of the tensions that had been building up. The Vega streaking in from deep-space made a shallow turn that took it into a pass at twenty miles #146; distance and vanished once more into the infinite cosmic backdrop.

Hunt turned to Danchekker, talking in a low voice, 'You know, Chris, it #146;s a funny thing. . . . I #146;ve got an uncle who lives in Africa. He says there are some places where it #146;s customary to greet strangers by intimidating them with screams and shouts and brandishings of spears. It #146;s the accepted way of establishing your status.'

'Perhaps they regard that as no more than a sensible precaution,' Danchekker said drily.

At last the optical cameras distinguished a bright speck in the middle-distance between J5 and the alien ship. A zoom-in revealed it to be a smooth, silver disk devoid of any appendages; as before, the view gave no clue of its true shape. It continued its unhurried pace until it was a half- mile from the command ship; there it came to rest and turned itself broadside-on to present a simple, unadorned egg-shaped profile. It was just over thirty feet long and appeared to be of entirely metallic construction. After a few seconds it began showing a bright and slowly flashing white light.

The consensus arrived at in the debate that followed was that the egg was requesting permission to enter the ship. The communication time lag to Earth did not allow immediate consultation with higher authority. After sending a full report Earthward via the laser link, Shannon announced his decision to grant the request.

A reception party was hurriedly organized and dispatched to one of Jupiter Five #146;s docking bays. The docking bay, designed for maintenance work on J5 #146;s assorted daughter vessels, carried a pair of enormous outer doors which were normally left open, but which could be closed when circumstances dictated that the bay be filled with air. Access from the main body of the ship was gained through a number of smaller ancillary airlocks positioned at intervals along the inner side of the bay. Clad in spacesuits, the reception party emerged onto one of the vast working platforms in the docking bay and set up a beacon adjusted to flash at the same frequency as that still pulsing on the egg.

On the bridge of Jupiter Five , an expectant semicircle formed around the screen showing the docking bay. The silver ovoid drifted into the center of the starry carpet separating the gaping shadows of the outer doors. The egg descended slowly, its light now extinguished, then hovered some distance above the platform as if cautiously surveying the situation. A close-up showed that in several places on its surface, circular sections of its skin had risen above the overall outline, forming a series of squat, retractable turrets which rotated slowly, presumably to scan the inside of the bay with cameras and other instruments. The egg then resumed its descent and came gently to rest about ten yards from where the reception party was standing in a tight, apprehensive huddle. Overhead an arc-light came on to bathe it in a pool of white.

'Well, it #146;s down.' The voice of Deputy Mission Director Gordon Storrel, who had volunteered to lead the reception party, announced on an audio channel. 'Three landing pads have come out from underneath. There #146;s no other sign of life.'

'Give it two minutes,' Shannon said into his microphone. 'Then move forward to the halfway point, slowly. Stop there.'

'Roger.'

After sixty seconds another light was turned on to illuminate the group of Earthmen; somebody had suggested that to have the party seen as shadowy forms lurking in the gloom could give an undesirably sinister impression. The action produced no response from the egg.

At last Storrel turned to his men. 'Okay, time #146;s up. We #146;re moving in.'

The screen showed the knot of ungainly, helmeted figures walking slowly forward; at their head was the one bearing Storrel #146;s golden shoulder-flashes, and on either side of him a senior UNSA officer. They halted. Then, a panel in the side of the egg slid aside smoothly to reveal a hatch about eight feet high and at least half that wide. The figures in the spacesuits stiffened visibly and the watchers on the bridge braced themselves, but nothing further happened.

'Maybe they #146;re hung up about protocol or something,' Storrel said. 'They #146;ve come into our den. Could be they #146;re telling us it #146;s our turn.'

'Could be,' Shannon agreed. In a quieter voice he asked Hayter: 'Anything to report from up top?' The captain activated another channel to speak to two UNSA sergeants positioned on a maintenance catwalk high above the platform in the docking bay.

'Come in, Catwalk. What can you see?'

'We #146;ve got a fair angle down inside it. The inside #146;s in shadow but we #146;ve got an image on the intensifier. Just pieces of equipment and fittings . . . seems crammed pretty full. No movement or signs of life.'

'No signs of life visible, Gordon,' Shannon relayed to the bay. 'It looks as if you can stay there forever or have a look. Good luck. Don #146;t think twice about backing off if anything #146;s even slightly suspicious.'

'No chance of that,' Storrel told him. 'Okay, fellas, you heard. Never say UNSA doesn #146;t live up to its job ads. Miraiski and Oberman, come with me; the rest of you, stay put.'

Three figures moved, forward from the group and paused near a small ramp that had telescoped from the bottom of the hatch. Another screen came to life on the bridge to show the view picked up by a hand-held camera operated by one of the UNSA officers. For a second it held a shot of the yawning hatch and the top of the ramp, and then a back view of Storrel filled the screen.

Storrel #146;s commentary came through on audio. 'I #146;m at the top of the ramp now. There #146;s a drop of about a foot down to the deck inside. There #146;s an inner door on the other side of the entrance compartment and it #146;s open. Looks like an airlock.' The TV picture closed in as the camera operator moved up beside Storrel; it confirmed his description and the general impression of cramped and cluttered surroundings that had been gained from the catwalk. A glow of warm, yellowy light penetrated the lock from beyond the inner door.

'I #146;m going through into the inner compartment. . . .' A pause. 'This looks like the control cabin. It has seats for two occupants sitting side by side, facing forward. Could be pilot and copilot stations #151;all kinds of controls and instruments . . . No sign of anybody, though . . . just one other door, leading aft, closed. The seats are very large, in scale with everything else about the general design. Must be big guys. . . Oberman, come on through and get a shot of it for the folks back home.'

The view showed the scene as Storrel had described, then began sweeping slowly around the cabin to record close-ups of the alien equipment. Suddenly Hunt pointed toward the screen.

'Chris!' he exclaimed, catching Danchekker #146;s sleeve. 'That long gray panel with the switches on. . . did you notice it? I #146;ve seen those same markings before! They were on #151;'

He abruptly stopped speaking as the camera swung sharply upward and focused on a large display screen that was set directly in front of the egg #146;s two empty seats. Something was happening on it. A second later they
