11. It was decided that the spectra signal spotted from orbit by Mars Odyssey was produced by these spherules . 12. Not only are there spherules on the surface but they are also found deeper in the Martian soil. 13. They found that the spherules spread out evenly and randomly inside the rocks, and not in layers. 14. It is able to move about slowly and maintains territory by stinging genetically unrelated anemones with its spherules . 15. The spherules found in the ice may originate from terrestrial debris ejected into the atmosphere by an impact event. 16. Mission scientists reported on March 2 that they concluded a survey of the distribution of spherules in the bedrock. 17. This discovery seems to strengthen the conclusion, that spherules are concretions, grown in wet condition with dissolved iron. 18. On March 2, Opportunity mission scientists reported that they concluded a survey of the distribution of spherules in the bedrock. 19. A re-evaluation published by the original proponents in June 2013 of spherules from 18 sites worldwide supports their hypothesis. 20. Transmission electron micrographs show that it is generally made up of aggregates of hollow spherules ~ 3-5 nm in diameter.
