📦 🚐 How may #microlaunchers compete with #Starship 🚚 ?

It's not all about #LaunchCost, but also time ⏱️ to (the exact) #orbit. See "Do you prefer dedicated microlauncher flights or #rideshares on heavier launchers" and "What are the advantages of a dedicated launch on a #microlauncher" https://www.rolandberger.com/en/Insights/Publications/Small-Satellites-and-the-growing-demand-in-microlaunchers-and-ridesharing.html
