Logbook #75


Zara raised her eyes and slowly took in the vault of the heavens. Dots and shimmers of light beckoned to her from every which way. Sighing, she wondered how so few stars could raise such strong emotions and vibrant conjecture. She remembered an earlier class where the instructor had said that with the bare eye people could see only a few thousand stars at best. And somehow those few stars drew aspirants on. She could spend and has spent countless hours contemplating the dots, the Earth and her existence. While no grandiose schemes miraculously appeared in her mind, she happily felt humbled and devinely curious as to what lay in store for her and the heavens.

She traced her eyes through the familiar constellation of the Southern Cross and down to the patch of regolith in front of her.

“It’s much as we’d imagined” she reported back to Xu in the Hab. “This patch of lunar dust looks exactly like every other dust heap around” she continued, then laughed. “Perhaps their maid’s taken the day off. Or the last few billion years off.”

“Keep looking” implored Xu’s voice over the intercom. “There may be shards of glass or a slight depression.”

Xu was hoping to find the impact spot of a small asteroid. Their local seismographs had triangulated a recent disturbance somewhere nearby. The equipment’s accuracy wasn’t great, probably due to its lack of sensitivity. From a few previous events the colonists had build a log lunar strikes versus seismograph readings. They didn’t have enough points to have a reliable sample so they valued every chance to add another. The latest event could have been from a tennis ball sized bit of asteroid. If they could find it then they could add one more point to calibrate the seismograph as well as learn a bit more about ‘heavenly’ particle interactions.

Zara was undertaking the standard ground sweep pattern. Nearby, Woof helped by setting a reference point from which she could stay on course. She was slowly stepping through, or really shuffling through the regolith. Trying to use her feet to detect the expected cone-shaped depression. Given the low angle of the Sun she was also keeping an eye out for oddly shaped depressions at the surface of the regolith. Yet, as she continually found when doing assaying, the Moon’s surface was for the most part oddly shaped in every which way. There were shallow depressions and abrupt, sharp holes. Cliffs would tower nearly straight up above her while others gently sloped like a primordial shield volcano. And immediately adjacent to these were flat lands or marias that spread across from horizon to horizon. This variety held sway with little attention to rock composition. After the weeks on the Moon, Zara was getting much more used to selenology, associating various ground patterns with rock types and chemical compositions. She knew that she was in a slight depression and even though there was no atmosphere to move dust around, the depression had a greater depth of regolith in the centre than on the edges. Actually the northern edge had no regolith and was likely the lip of an old, small impact crater. So, in a sense, she was looking for a crater within a crater. Not an easy task.

She paused and looked up again. She was sad that she would never see a meteor shoot across the sky. Without an atmosphere, any asteroid would either strike the Moon or go sailing directly by. Unless the Sun glinted off its edges, no human on the Moon would ever know of its existence. She had once imagined herself standing on a lunar mountain top and holding up a hand to try to grab one as it flew by on its long elliptical orbit about the Sun. She knew that she could never stop an asteroid. And even the impact of a speck of dust could prove lethal. But, if the opportunity ever presented itself, she would raise her hand and try.
