I guess this means they&#x27;re taking a &quot;better to ask forgiveness than permission&quot; attitude towards planetary protection? Musk is on the record as not being worried about contaminating Mars with Earth life, and it seems like a 2 year time frame wouldn&#x27;t give them time to put together a JPL-style clean room operation. Is there anything that NASA could&#x2F;would do to stop them from landing a &#x27;dirty&#x27; Dragon on Mars?
