This is a meteoroid in space, which strikes an object while still in space. If anything survives, it would be reasonably called a meteorite. So you go from meteoroid to meteorite with no meteor phase in between. The same scenario would apply to lunar meteorites. It is not necessary to have a me

Well, a solid body would have to produce the characteristics of a meteor wouldn't it? We know a solid object produces a meteor. Be it grain sized (as in meteor showers) or large size as in Hoba for example. Just asking! Regards! Tom __ Visit the

The shield is clearly protecting against meteoroids. I don't think this is ambiguous at all. Similarly, one might want to protect Earth from asteroid impacts, but you would not say it needed protection from meteorites. It isn't the leftover bits that present the hazard... it is the incoming p

This does not make the terms well defined. It is only a proposal for a more complex set of definitions. And even if widely adopted, it does not remove the ambiguity in the case of this protective space shelter. If the shelter is struck by a meteoroid, which then vaporizes, was it a "meteoroid

Here is how Rubin and Grossman (2010) [MAPS 45, 114-122] dealt with this: Another difficult situation arises when considering projectiles that strike a spacecraft. For example, publications reporting on the Long Duration Exposure Facility (LDEF), which was exposed to interplanetary space in lo

They might reasonably call it an anti-meteoroid shelter, but the fact is, "meteorite" is not well enough defined to say that once a meteoroid impacts an object in space, it can't be called a meteorite. I don't have a problem with the usage in the article. Meteoroid and meteorite are reasonably

Hi, all, I don't recall this being discussed here before and hopefully I'm not being too anal, but is the definition of "meteorite" evolving, or is it being used improperly here (and frequently in the past when referring to the ISS and these shields). Cheers, Pete http://rbth.ru/articles
