The upper half, semiflexible with jointed arms ending in gloves from which by contorting the shoulders the hands could be withdrawn into the sleeves when not in use. A metal and tinted plastic helmet with earphones, mike and chin switch. An oxy air-conditioning and reprocessing unit with its spare pure oxygen tank; on this he could possibly depend for twelve hours given no undue exertion and with the most rigid economy all the time. The power pack for suit operation and radio had a safety margin of one hour over the maximum air supply, if the radio wasn't used. At this time Johnny couldn't see much use for it. Item: One Waste Disposal Cylinder, expendable, complete with motor and full fuel tanks, packed, according to his loading manifest with sundry supplies to avoid dead stowage space. Seldom used, since most station waste was ferried down in the otherwise empty service ships, they occasionally handled certain laboratory refuse it was considered best to destroy in space. The cylinders were decelerated and allowed to fall into atmosphere where the friction of the unchecked plunge burned up what the magnesium charge inside had not already. The rest of the shipwrecked material had by now drifted beyond easy reach and Johnny did not feel like wasting fuel rounding it up. Position? A matter of memory and some guesswork by now. Some ten minutes out of powered flight at the time of collision, coasting up to station orbit where a quick boost from the jets would have made up his lost velocity to orbit standard. But there would be no boost now. So he'd just fall off around the other side, falling around and into Mother Earth, to skim atmosphere and climb on past and up to touch orbit altitude--and down again. A nice elliptical orbit, apogee a thousand odd miles, perigee, sixty-seventy--perhaps. How much speed had he left? How long would it be before he brushed the fringe of atmosphere once too often and too deep? Just another meteor. And survival. A comparatively simple problem since the mechanics of it were restricted by a simple formula in which his role would seem to be a passive one. To survive he must be rescued by his own kind in twelve hours or less. To be rescued he must be seen or heard. Since his radio was a simple short-range intercom it followed that he must be seen first and heard later. Being seen meant making a sufficiently distinguishable _blip_ on somebody's radar screen to arouse comment over a _blip_ where, according to schedule no orbiting _blip_ should be. * * * * *
