Firing It Up at Both Ends? New Launch Vehicles Extend Mass Range - Via Satellite - Mar 2018
"Falcon Heavy has nearly doubled the launch range from a former 14.2 tons to Geostationary Transfer Orbit (GTO), via Delta 4 Heavy, to a whopping 26.7 tons. It has also globalized SpaceX’s addressable market, previously limited to Falcon 9’s capability of 8.3 tons to GTO (and a much smaller 4.5 tons when Falcon Heavy was first announced). Turning to the market’s other new entrant, Rocket Lab’s Electron launch vehicle addresses payloads with a nominal mass of 150 kg and up to 225 kg, reducing the lower limit of the orbital class market by several hundred kilograms."

"With a market Northern Sky Research (NSR) expects to double in the next five years, and a trend of increasing mass from sub-10 kg cubesats to 50 kg-plus microsatellites, Electron’s relevance to the market is evident.

The significance of extended heavy-lift capacity to the market is less clear. "

"Headwinds in the commercial GEO market have gutted demand for manufacturing and launch, with operators striving more than ever for capital expenditure efficiency via delayed procurements and cost-saving designs. Rates of adoption of electric propulsion and digital payloads have surged, reducing average satellite mass. Current demand is thus well addressed by existing launch services, with even new appeal of dual launches on Proton and triple launches on Ariane 5 to further reduce capex with mid-sized GEOs."
