||1997: William Leonard Edge dies ... mathematician most known for his work in finite geometry. In the 1950s Edge began to explore vector spaces over Galois fields as an entry to finite geometry. Points and lines of finite projective geometry arise as lines and planes in these spaces, and the projectivities of these spaces provide representation of some finite groups.

File:Dawn spacecraft model.png|link=Dawn (spacecraft) (nonfiction)|2007: NASA launches the ''[[Dawn (spacecraft) (nonfiction)|Dawn]]'' space probe. It is NASA's first purely exploratory mission to use ion propulsion. ''[[Dawn (spacecraft) (nonfiction)|Dawn]]'' will study Vesta and Ceres, two of the three known protoplanets of the asteroid belt.
