DESCRIPTION:I report the status of a research program to compute scatterin
 g between the past and future horizons of an observer in de Sitter space. 
 I focus on Yang-Mills theory and the self-dual sector of General Relativit
 y\, both at tree level. Helicity plays the same key role as in the asympto
 tically flat S-matrix\, in contrast with the more standard de Sitter probl
 em of inflationary correlators.\nAlong the way\, I construct a lightcone a
 nsatz for self-dual gravity solutions in the Poincare patch\, using Kirill
  Krasnov's wondrous chiral formulation of GR.
