The scientists aboard the station had reasoned that if the alien world had a lower gravity, it probably also had a lower atmospheric pressure. They stopped adding air at about seventy kilopascals.

The aliens seemed to find all this suitable. The robotic arms on one of the spheres folded back on themselves so that they could touch the sphere's surface. The sphere split in two at its equator, and the hands, which were anch.o.r.ed to the bottom half, lifted away the top part.

Inside was a Centaur.

The actual Centaur looked nothing like its namesake from human mythology. It was jet-black in color, insectile in construction, with giant green eyes and great iridescent wings that unfolded as soon as the being had drifted out of its s.p.a.ce suit.

It was absolutely gorgeous.

Soon the other four egglike suits cracked open, disgorging their occupants. Exoskeleton color ranged from solid black through silver, and eye color varied from green through purple through cyan. The unfolding of the wings was apparently the Centaur equivalent of a stretch-no sooner had they been deployed than the beings folded them up again.

A door opened in the cargo bay, and the designated choice for first contact drifted into the room. And who better for that than the person who had first figured out what the Centauri radio signals were meant to convey? Who better than the person who had first detected the presence not just of humanity's overmind, but of the Centaur overmind as well? Who better than the individual who had mediated the first contact between the overminds, preventing the human one from panicking?

All five aliens turned to look at Heather Davis. She held out her hands, palms up, and smiled at the extraterrestrials. The Centaur who had first opened its suit unfolded its wings again, and with a couple of gentle beats, set itself moving toward her. A backward movement of the wings brought it to a stop about a meter from Heather. She reached out an arm toward the alien, and the alien unfurled a long, thin limb toward her. The limb looked fragile; Heather did nothing more than let it tap against the palm of her hand.

A dozen years ago, the Centaurs had reached out with their radio messages.

Two years ago, their overmind had made contact with the human overmind. Perhaps that had been the more important event, but still, there was something wonderful and poignant and real about the actual touching of hands.

"Welcome to Earth," said Heather. "I think you're going to find it a very very nice place." nice place."

The alien, who couldn't yet understand English, nonetheless tipped its angular head, as if in acknowledgment.

There were uncountable other humans plugged into Heather's mind, enjoying it all from her perspective. And, no doubt, all that the aliens were seeing was propagating back through their overmind, across the light-years to Alpha Centauri, where it would be experienced by everyone there.

Doubtless humans would soon be trying to do the Necker transformation into a Centaur's mind-indeed, some of those riding within Heather might be trying it right now.

She wondered if it would work.

But then again, it didn't really matter.

Even without that capability, Heather was sure that her species, which at last now deserved its name of humanity, was going to have no trouble seeing the other person's point of view.
