Thanks, Alan. Here's hoping for one more KBO encounter!

Thanks Alan - that's fantastic news! it's great to hear that the drive and energy to get the most out of NH continues unabated.
Good luck with the on-going search. |

Nice to hear of the capabilities of the Subaru telescope. Is there any chance of the Vera Rubin (LSST) telescope starting to come online in a useful way for NH in the next couple of years?

No stone unturned - I absolutely love the dedication to exhausting all the possibilities and utilizing every possible asset.
Awesome. |

Glad to hear! I'm always hoping for at least one more KBO flyby!

New PI Perspective gives details on the continuing search for a second flyby:
http://pluto.jhuapl.edu/News-Center/PI-Per...tive_03_23_2021 Also this teasing hint "And note that in mid-April, we'll have a news release, with some very special images we've taken from our perch so far away in the Kuiper Belt, so keep an eye out for that!" I have some educated guesses about what these might be.... |

50 AU has been reached (what an achivement!), and with it, an image of the starfield where Voyager 1 is:

DPS 53 Wednesday Press Conference contains, among others, two very interesting presentations:
- (from 2:16) „New Horizons discovers „Tight Twins” in the Kuiper Belt” (by Harold Weaver) - (from 19:00) OSIRIS-REx: „Why Bennu and asteroids like it have surplisingly rugged surfaces?” (by Saverio Cambioni) [S-type asteroids have low porosity rocks and... have abundant fine-grained materials / Carbonaceous asteroids have high porosity rocks and... lack fine-grained materials] https://www.youtube.com/watch?v=V5UudvSoE0o |

Just bumping the thread - I'm not aware of any recent news on potential future KBO flyby candidates (I'm sure we'd have heard...)
Reading back through the thread, it seems NH itself is the best chance of turning up a suitable candidate, but with JWST nearing full commission, are there any plans to use the telescope in this regard? Is it capable enough to help in the search? |

JWST would be an unlikely choice for a survey: It has a small field of view and very valuable time. HST was used to find Arroketh, but HST also has a longer lifespan than JWST will have.

The best search tools are wide field cameras on large glass telescopes that can go very deep. These include cameras on Subaru and JWST, but the large amount of observing time required makes JWST unlikely to award the time. We have made significant advances with machine learning techniques to detect faint KBOs and are putting a wider filter on Subaru to also help, but the search remains a needle in a haystack problem with formally low odds of success owing to the low fuel state of New Horizons.
