`` Hannah! HANNAH!... I found something!'' 
 
 I quickly turned back to the bit of material sticking out of the Terran dirt while Hannah shone her helmet lights my way. 
 
 `` That's most unexpected!'' She exclaimed as she arrived. `` This area was supposedly very remote!'' 
 
 We were here looking for DNA of various species in an effort to repopulate our own planet after an unfortunate series of choices led to the extinction of most of our own native species. Terran history records indicated that this portion of North America had been wilderness, hundreds of kilometres from the nearest aggregation of crumbling structures. 
 
 The object I now pondered was in pretty rough shape. The edges were torn suggesting it was only a part of something larger. In it's current condition it was shaped like a bowl that began to close in on itself slightly and was no bigger than my fist. 
 
 `` Let me see'' Hannah said pulling out her spectroscopic analyzer. I handed her the object and the little laser pulsed against the substance multiple times causing some dark acrid smoke to arise which the analyzer subjected to spectroscopic analysis. Shortly after some information appeared on our helmet HUDs. `` Hmm, a material harvested from Hevea brasiliensis which Terrans used for a lot of things'' I muttered thoughtfully. `` Let's keep digging!'' I said and bagged the object. 
 
 Later that day we found two more objects, one was a degraded pouch of some kind, made of synthetic materials, and larger than the first item, but slightly smaller than a typical helmet, and the other was a large flat object about 5 feet by 4 feet in size and about 3-4 inches thick. It appeared to be built out of the same material as the pouch, and could be folded over. After cutting into it we discovered a thin sheet of firm plastic on top of a heavily degraded spongy material. 
 
 `` Maybe we've got it upside down?'' Hannah suggested. `` Maybe it's a type of mobile mattress and the plastic is to prevent anything from below poking through?'' I regarded it for a moment, but then why is the fold on this side? that Would make sleeping on it terribly uncomfortable. Besides, the average Terran was taller than this thing is long so it would n't make for a very good mattress, unless intended for children.'' 
 
 `` Well let's get it back to the lander and we can do some more thorough analysis there'' Hannah suggested and then yolo'd into the sunset. 
 
 EDIT: spelling 
 
 EDIT2.0: changed thickness of third item from 5 inches to 3-4 inches
