The recent movement in the space sector was ignited by Rocket Lab's $80 billion acquisition of Iridium: $Planet Labs(PL.US) rose +16%, with no company announcement, purely driven by sector sentiment; $Astrotech(ASTC.US) surged +31%, with its lunar resources/quantum supply chain strategy and explosive detection system receiving European ECAC certification, giving it a more substantial story than $Planet Labs(PL.US); $Tema Space Innovators ETF(NASA.US) rose nearly ten points, lifting the entire basket; $Virgin Galactic(SPCE.US) remained flat, as suborbital tourism is separated from the Iridium acquisition by a valuation tier, and funds didn't flow there.

At the sector level, today's movement clearly followed two lines: software and manufacturing. The key was the revaluation of targets like Iridium, which combines "satellite operations + IoT." One should be alert to corners where constellation brands haven't moved—theme heat typically first lifts ETFs, then filters down to select specific targets.
