We present high angular resolution (12"-24") and high-sensitivity ¹²CO and ¹³CO J=2-1 and J=1-0 observations of the HH 1-2 outflow. The observations show the molecular counterpart, moving with a velocity of ≃30 km.s^–1, of the optical bipolar system driven by the VLA 1 embedded source. Along with the optical jet there are certain regions where the molecular gas reaches deprojected velocities of 100-200 km.s^–1 and that we interpret as the molecular jet. The bipolar CO outflow has a length of ∼260" with a curved morphology toward the north where it extends beyond the HH 1 object (≃120"). Two new molecular outflows have been detected, one arising from IRAS 05339-0647, which excites the HH 147 optical flow, and another powered by VLA 2, which drives the HH 144 optical outflow. The molecular outflow driven by the VLA 3 source is also clearly detected and spatially resolved from the VLA 1 main outflow.
