Masten Space Systems has another in their rapid-fire series of posts on tether testing, including videos. As with the others, this one shows steady progress over earlier ones. The Masten folks are feeling like it's slow going, but from here, with a peek at progress every day or 2 (and not having to slog through all the work) it seems like they're really moving fast.
Early morning update (June 26): More testing, slightly better results
