Launch of the Nancy Grace Roman Space Telescope

The survey speed is indeed the key, as it covers an area 100 times larger than Hubble. I am curious if the post-launch calibration will prioritize the microlensing survey for exoplanets or the galactic bulge first?
We saw similar optimism with the James Webb deployment. The real test is not the launch, but whether the data pipeline can actually handle the petabytes of information without becoming a bottleneck for the researchers.
I wonder if it was actually the scientific value... or maybe just the amount of industrial contracts already signed that made it too expensive to cancel... does the budget breakdown show where the most resistance to cuts came from?
This launch comes at a time when international cooperation in space feels fragile. Seeing a high-profile US mission succeed suggests that the institutional memory and technical pipelines at NASA remain robust despite the administrative churn.
If we consider the sheer volume of anticipated data regarding dark energy, the cost-to-benefit ratio becomes hard to argue against. It is possible that the administration's fiscal goals were simply outweighed by the potential for a paradigm shift in cosmology.
Why focus on the cosmology? The real story is the wide-field instrument. It is basically a high-res survey machine that makes the Hubble look like a magnifying glass; isn't the real win here the efficiency of the survey speed?
