After launching the FireFly probes in 2015, the company seeks to launch a larger craft, named DragonFly, in 2016 which will be able to return between 30 to 60 kgs ofmaterial to Earth.
Note that the real return since 1926 is almost 1% per year higher, a fairly material difference in terms of returns, and yet the nominal return was almost identical (9.9% annually since 1926 versus only a slightly lower 9.7% since 1957).
The U.S. and its allies are seeking to gain Iran's willingness to suspend its production of near weapons-grade nuclear material at its uranium-enrichment sites in return for economic incentives.
Defence Secretary Philip Hammond said the returnof troops from Germany marked the end of an era, and thanked the German government and people for their "material and moral" support.
