The preliminary report is that #JWSTCycle5 was another record-breaker! Well done everyone 👏🔭 Can't wait to see our slate of new #MIRI programs for the new cycle (though we will have to wait until 2026 for that).

And it's a wrap: one PI and six co-I proposals submitted (and then a nice Boulder autumn run!) #JWSTCycle5
