It's an interesting event, but this article is a bit misleading, and the title outright wrong : the object did not reach space in any meaningful way, and Robert Brownlee never said that it did. In fact, since meteors with a similar weight coming in at a third of the lower bound of the manhole's velocity can not reach the surface, we can assume that the manhole burned up in the atmosphere pretty quickly.<p>From <a href="https://nuclearweaponarchive.org/Usa/Tests/Brownlee.html" rel="nofollow">https://nuclearweaponarchive.org/Usa/Tests/Brownlee.html</a> :<p>> As usual, the facts never can catch up with the legend, so I am occasionally credited with launching a "man-hole cover" into space, and I am also vilified for being so stupid as not to understand masses and aerodynamics, etc, etc, and border on being a criminal for making such a claim.
That would be a big nope:<p><a href="https://www.centauri-dreams.org/2025/01/07/a-manhole-cover-beyond-the-solar-system/" rel="nofollow">https://www.centauri-dreams.org/2025/01/07/a-manhole-cover-b...</a>
