Upon reading "An empirical examination of WISE/NEOWISE asteroid analysis and results": As I understand it, nothing is wrong with the data obtained from the missions. What is wrong is the interpretations/inferences drawn from the data. As I understand it, the data consists of multi-spectral analysis of various asteroids. From that data, the sizes of those ...

We want to find NEOs that are inside Earth's orbit, like Atens, and telescopes don't like looking close to the Sun. So the more inside the orbit of the Earth you can get, the more new NEOs you will find without having to look at the Sun. Ideally you'd like a NEOCAM near the orbit of Venus. Then you'd be able to catch 'em all. But at E-S L1, you'll find most ...

The new mission is going to be called NEOSM for NEO Surveillance Mission according to Twitter messages from committee members (example) or this Arstechnica article - which isn't a lot to go on. More information may emerge if the presentation slide decks are released on the Planetary Science Advisory Committee website after the meeting concludes on 2019-09-24....

In theory, a smaller telescope can see a dim object by just looking longer than a larger one. There are issues of noise and stability that limit this, but for small factors it works. So their plan seems to be to break up a large-telescope observing plan into plans for longer observations with multiple smaller telescopes. This (somehow) saves lots of cost. ...
