Global spending on space launch activities is forecast to spike to over $9 billion in 2013 — up from $6.7 billion in 2011 — and then steadily decrease to $8.36 billion by 2020, according to a new study from Frost & Sullivan’s Aerospace & Defense practice.

“The global commercial space launch market will transition from the oligopoly of United Launch Alliance (ULA), Arianespace and International Launch Services (ILS) to a more competitive market with several, smaller companies that manufacture cost-effective launchers,” the Mountain View, Calif.-based consultancy said in a Feb. 6 statement.
