#10 is very pleasing to look at, but the 's' shape at the beginning is too abstract to stand alone. Needs a more unique shape, or place existing shape into the actual word. For instance, if the 's' shape replaced the actual letter s, or was converted into a p, it might be a stronger logo.
Entry #60 is unique and fluid. Would you mind substituting another font? Also, an orange sphere is too sun like. You can use alternate color of your choice.
