Current status: gardening with a view. Had to harvest ~1/4 of my onions early because somebody has a habit of trampling on them in search of the ball…

If you don't read the paper, at least enjoy this movie of our Figure 2! In this simulation, q is the particle's pericenter, normalized to the primary's long axis. The point is that you need q>1 to avoid reimpacting the primary during pericenter passage, and that is not always easy!

In Japan for the next 10 days for a few exciting meetings. Today and tomorrow, I am at JAXA’s ISAS for a Hayabusa2# science team meeting. What a great excuse to visit when the cherry blossoms are in full bloom!

Playing around with some renderings of DART impact ejecta simulations. It’s amazing what you can do with @matplotlib.org and @reboundbot.bsky.social !

New (to me) handmade table and chairs found at a flea market in Nice. Restoring it now with some beeswax. €100 and will probably outlive me. This room is finally coming together!

I decided it would be a good idea to procrastinate on job applications and play some Kerbal Space Program instead. Using a mod to play with a 1/9 scale real solar system, did a nice Voyager style mission. Here are my Jupiter and Neptune/Triton flybys :)

Another one. This paper is “The feasibility of deflecting asteroid 2017 PDC using neutral beam propulsion” by DeCicco et al., 2019 (Don’t worry, 2017 PDC is not a real asteroid!)

I found a fun Easter egg in For All Mankind. They used real DART papers as props for a scene related to altering the orbit of an asteroid! On the left is Rivkin et al. 2021 and on the right is Hirabayashi et al. 2022.
