We Recovered Shock-Resisting Steel in the Debris Field of the First Recognized Interstellar Meteor, IM1
On Run 6 of the magnetic sled through the likely crash site of the first recognized interstellar meteor, IM1, the expedition research team recovered shards of corroded iron. At first, we thought it may be common industrial iron associated with human-made ocean trash. But when Ryan Weed ran the sample of shards through the X-ray Fluorescence (XRF) analyzer, the most likely alloy it flagged is X5 steel with titanium, which is also known as shock-resisting steel.
