A constellation of identical 3U CubeSats provide sounding (left CubeSat has a temperature profile of a simulated Tropical Cyclone (TC) from a numerical weather prediction (NWP) model) and 12-channel radiometric imagery (center CubeSat has simulated radiances from NWP model and radiative transfer model and the near right CubeSat has a single-channel radiance image of a TC) with a median revisit rate approaching 60 minutes to meet state-of-the-art performance.The Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) mission will provide rapid-refresh microwave measurements over the tropics that can be used to observe the thermodynamics of the troposphere and precipitation structure for storm systems at the mesoscale and synoptic scale over the entire storm lifecycle. TROPICS comprises a constellation of CubeSats in three low-Earth orbital planes. Each CubeSat will host a high-performance radiometer scanning across the satellite track at 30 RPM to provide temperature profiles using seven channels near the 118.75 GHz oxygen absorption line, water vapor profiles using 3 channels near the 183 GHz water vapor absorption line, imagery in a single channel near 90 GHz for precipitation measurements, and a single channel at 205 GHz for cloud ice measurements.More Information: https://tropics.ll.mit.edu/CMS/tropics/Mission-Overview
The latest aerial images from NASASpacefligt indicate that there is nothing at SLC-46.
However Astra can probably set up in 24 hours by staging from somewhere close by in Florida. IIRC everything for the launch was in 3 or 4 semi trailers.
The issue that might hold up the launch set up process might be the readiness of the payload.
At this morning’s Earth Science Advisory Cmte meeting, NASA’s Karen St. Germain says the agency is working on a plan for launching the four remaining TROPICS cubesats after the first two were lost on an Astra launch in June. “Still excited” about science 4 TROPICS sats can do. [August 2]

Losing one more TROPICS will drastically reduce the science that can done, since nominally there should be a minimum of 4 TROPICS spacecrafts gathering data. NASA has let Astra Space rolled the dice, who didn't make the saving throw.

NASA has let Astra Space rolled the dice, who didn't make the saving throw. I mentioned that possibility a while ago, and someone said that since TROPICS is not going to a sun-synchronous orbit (TROPICS operates in a 30-degree orbit), a Transporter rideshare is unlikely.
What are the benefits and disadvantages of TROPICS operating in a 53-degree orbit rather than the original 30-degree orbit?

Does this tweet mean that the mission is not cancelled and that it just moves to Rocket 4.0?"NASA is an unreal customer. Told Astra it's willing to wait for "launch system 2.0" for the Tropics mission."
