Curious if anyone has written about why estimates of the prevalence of small meteoroids at the L2 point were (possibly) too low? Were the estimates based on data about meteoroid prevalence entering the Earth atmosphere, and the prevalence is different at the L2 point?
- vanattab 4y agoI am not sure if the answer you seek is in here because I only have access to the abstract but here is a paper studying the effect of meteoroids on the jwst mirrors. https://adsabs.harvard.edu/pdf/2004ESASP.538..417S https://adsabs.harvard.edu/pdf/2004ESASP.538..417S https://www.spiedigitallibrary.org/conference-proceedings-of-spie/8442/84423A/Optical-transmission-for-the-James-Webb-Space-Telescope/10.1117/12.924841.short https://www.spiedigitallibrary.org/conference-proceedings-of... https://www.sciencedirect.com/science/article/abs/pii/S0734743X03001234 https://www.sciencedirect.com/science/article/abs/pii/S07347...
- belter 4y agoSounds like the estimates about micro-meteoroids at L2 were too low.
