Two satellite launches planned for this fall #AEHF4 and #SBIRSGEO4 are being delayed to 2018 due to separate issues https://spaceflightnow.com/2017/08/02/two-u-s-military-satellite-launches-delayed-into-next-year/ …pic.twitter.com/xD1IgQRlaG

#SBIRSGEO4 got a free pass due to the #IMAGE recovery unlike #SBIRSGEO3 that was tracked all the way up... Ironically, GEO 4 has arrived at 159W and is putting out a decent S-band signal. SBIRS GEO 4 seems to be replacing DSP F20. Welcome SBIRS GEO 4 to the neighbourhood.pic.twitter.com/Bcqi7UKaes
