The space sector is catching its breath Wednesday, and for the first time since SpaceX (NASDAQ:SPCX) went public last week and triggered a sector-wide selloff, many publicly traded space names are green.

Momentus Inc. (NASDAQ:MNTS) and AST SpaceMobile, Inc. (NASDAQ:ASTS) are leading the charge with specific catalysts behind their moves. 

ASTS stock is climbing. See the chart and price action here.

Momentus’ New Contract

Monmentus shares are up 9.04% to $10.15 intraday. Wednesday's strength follows a new contract announcement with the University of Colorado Boulder’s Laboratory for Atmospheric and Space Physics, where Momentus will host and operate the Occultation Wave Limb Sounder mission aboard its Vigoride-9 Orbital Service Vehicle. 

The deal adds an academic customer to a roster that already includes NASA and the U.S. Department of Defense.

MNTS stock remains up more than 100% year-to-date despite a 27% drop on June 12 after pricing a $25 million registered direct offering.
