Martian Technology: Science Pins and Pingers

These devices have been featured so far in In the Shadow of Ares and quite prominently in Redlands and He Has Walled Me In.

A science pin, as described in ItSoA, is a device shaped like a scaled-up golf tee, with a stem 1-1.5m long, and a head 100-150mm across and anywhere from 50mm to 400mm tall. The stem contains common power generation, storage, and management functions, and in the field is mounted to a peg or sleeve drilled or driven into the soil or rock.  The head consists of one or more cylindrical modules of different heights and a wide variety of functions. These modules thread together at the center with a common physical and electrical interface.

In all applications there is a communications and C&DH (command and data handling) module. This module links the pin to local and satellite communications networks, as well as to specialized instruments such as seismometer arrays or deep soil probes which are not located on the pin itself.

Modularity and standardization make it possible for science pins to be quickly emplaced and easily maintained, and readily upgraded with new or additional instruments as needed. The size and external features of the modules make them easy for suited settlers to handle with gloved hands.

Lindsay Jacobsen is shown in ItSoA maintaining a science pin she had previously deployed to monitor ground water for evidence of biological activity.

In HHWMI, Leon Toa has a strange encounter with a strange science pin in the Wilds.

Redlands prominently features a gold-plated science pin, and the action is set at one of the settlements where the devices are manufactured.

In Ghosts of Tharsis, we introduce a specialized application of the science pin concept, the “pinger”. A pinger is a science pin used as a navigation aid, particularly during mild to moderate dust storms when travel by rover is still somewhat feasible. The head of a typical pinger is a single mass-produced module containing navigation strobes and the power storage required to operate them for a month or more. The head is crowned with a passive reflector that rover navigation radars can use for distance and triangulation measurements.

Pingers at intervals and in problem-prone locations include additional instruments to monitor local weather conditions and transmit them back to a central data hub for use in travel planning.

I particularly liked the idea of reusing science pin components as the basis of navigation aids, as it reflects a potential real-world solution to the problems of navigating across a landscape with minimally-developed roadways prone to obscuring by dust. It has the added benefit of eliminating the ability of the MDA to bring to a halt surface transportation among the independents by scrambling the signals from the positioning satellites on which they have a Charter-granted monopoly. But most importantly for our purposes as authors, it makes possible a dramatic rover chase in a Class 1 dust storm…
