One participant regards an Orion drive as physically plausible and potentially useful once away from Earth. Another emphasises the consequences of failure and the problem of slowing down. Turning the spacecraft to reverse thrust is raised in reply. Radioactive material and exposure remain concerns in the discussion. This is a high-level assessment of a real proposed propulsion concept, with no engineering design established.

Debating Orion nuclear-pulse propulsion
An Orion drive is defended as potentially useful in space, while its operating hazards and use near Earth remain disputed.
