Someone with actual standing, unlike in Texas, is suing over the Mississippi law, hence why the SCOTUS is now willing to hear a case on these pre-viability laws. Date is now set for December 1st, and arguments will be in-person.

SCOTUS is also taking up access to concealed and other public carry laws, such as in the state of New York, which makes it impossible for every day citizens to acquire permits. The SCOTUS are limiting the case to ruling whether or not a state can blindly deny permits without review of merit, when they are filed by ordinary citizens.
At issue is how much the Second Amendment protects the right of individuals to carry concealed weapons outside their home for self-defense. The case will likely be argued in the fall.

The court currently stands at
3-3-3 Progressive-Libertarian-Conservative Justices, with the Libertarians being big on both existing, Supreme Law, and separation of powers, including sending things back to Congress and States. It will be interesting to watch how this all unfolds.
E.g., it's very likely the Libertarians could swing in either direction, depending on the arguments made by the 2 parties. Do they side with state's rights in both cases? Or do they argue the precedents of prior, Supreme Law on the individual rights of women and citizens alike, over the state? Or do they split?
