2 . survived the spaceflight; two other speciment. The 30-day report on this experiment will contain more results, but the full micrometoerite analysis will take some time. S-5 and S-6: These experiments were not officially carried, but nonetheless it was done as "operational procedure." In all some 300 color pictures were taken with the Hasselblad and Maurer cameras both of which were carried (for the first time. The Maurer is eventually planned to replace the Hasselblad, but this has been slow in evolution.) A strip was taken over Peru where the weather happened to excellent. Features show up in these pictures which do not appear on any existing map; for example, a glacial lake in the Ange~ which do not appear on any existing maps. The Peruvian Embassy has been informed of this lake which may portend an avalanche hazard for villagesilocated below, The Peruvians have sent a military p-l,ane into the area to investigate . THis indicates the possible current use of such pictorial information . THe AMU exercise was unsuccessful. It proved to be too Im.lCh "work" under the present arrangements. It takes two hands just to control the body peeitionang . Hand-held photography during EVA for experiments looks "out of the question" at pres ent. J oc elyn R. Gill
