In Hermann–Mauguin notation, space groups are named by a symbol combining the point group identifier with the uppercase letters describing the lattice type. Translations within the lattice in the form of screw axes and glide planes are also noted, giving a complete crystallographic space group. These are the Bravais lattices in three dimensions:
Bradford A. Smith (September 22, 1931 – July 3, 2018) was an American astronomer and an associate of the International Astronomical Union. He was employed by the Voyager program, and discovered the moon Bianca (which orbits Uranus ) on January 23, 1986.

One big resonance relates to the effort that rose from Planetary Resources' remains: Last month, ConsenSys Space unveiled its first project, a crowdsourced satellite-tracking campaign called TruSat.
A space group is called symmorphic (or split) if there is a point such that all symmetries are the product of a symmetry fixing this point and a translation. Equivalently, a space group is symmorphic if it is a semidirect product of its point group with its translation subgroup. There are 73 symmorphic space groups, with exactly one in each ...
WASHINGTON (Reuters) -NASA affirmed on Wednesday a plan it set last year to work with Elon Musk's SpaceX in returning two astronauts from the International Space Station, saying it will do so "as ...
