Rev 1.4
Preface
In this paper I present some statistics characterizing astronautical activity in calendar year 2018.
In the 2014 edition of this review, I described my methodological approach and some issues of
definitional ambguity; that discussion is not repeated here, and it is assumed that the reader has
consulted the earlier document, available at http://planet4589.org/space/papers/space14.pdf (This
paper may be found as space18.pdf at the same location).
Orbital Launch Attempts
During 2018 there were 114 orbital launch attempts, with 112 reaching orbit.

The Arianespace-managed Soyuz launches from French Guiana are counted as European.
Electron is licensed in the USA but launched from New Zealand territory. However, in late 2018
New Zealand registered the upper stages from the Jan 2018 Electron launch with the UN. Based on
this, in rev 1.4 of this document I am changing Electron to count as a New Zealand launch vehicle.
Two launches failed to reach orbit (one Chinese, one Russian).
