Phase curves are highly diagnostic of asteroids- if there’s an issue, it’s collecting data over sufficient phase, when orbital mechanics won’t necessarily cooperate. The emergence of sky surveys (Pam-STARRS, ATLAS, and serendipitous ones like DECam and Subaru-HSC) means data may have been collected in routine surveying. A better question is sifting through mountains of ones and zeros. Basaltic asteroids are rarer, but not that dear; someone has to tackle this type.
Similarly, binarity may be detected by light curves, and other methods like occultation, astrometry, etc. In one way, it’s a matter of having lots of data, and spotting the interesting objects in the database. Assuming two quasi-spherical or ‘potato’ asteroids, this is a well-tackled problem. But the more irregular the asteroid, the weirder the light curve. A binary of two dogbones or tamarinds or whatever (just look at (152830) Dinkinesh and Selam) is no longer an exercise left to the reader.
And speaking of phase and light, the meteor question is not fully settled. When the Hayabusa and OSIRIS-REx capsules entered, we used them as known starting points, and observed their resulting “meteor” phenomena. At some point, someone will launch known “rocks” and use them as known “fake” meteorites, recording their reentries. But before we take that expense, we can still refine our numbers on what we have already. In the case of meteor cameras like MIOS, that’s cross-relevant to space junk, and ‘uncooperative objects’ (foreign satellites).
Let’s not forget HCN (hydrogen cyanide). Let’s not forget it, since I mentioned its importance two days ago.
