    Part of the story is everyone being shocked at being under budget and ahead of schedule. I don't know everything, but I think this is reasonably attributable to the fact that this is a retrofit of an obsolete spy satellite. The leftovers of the security sector will be the most advanced scientific space surveyor. I have to wonder what things would look like with different priorities.

    Roman is scheduled to launch tomorrow (Aug 30) on a Falcon Heavy rocket:<p><a href="https:&#x2F;&#x2F;www.space.com&#x2F;news&#x2F;live&#x2F;nancy-grace-roman-telescope-live-updates-nasa-readies-roman-for-launch-august-29-2026" rel="nofollow">https:&#x2F;&#x2F;www.space.com&#x2F;news&#x2F;live&#x2F;nancy-grace-roman-telescope-...</a>

    For some tasks, surveys in particular, field of view is critical. You would need many Hubble telescopes to do what Roman can do mapping everything out there.<p>&quot;What really makes Roman stand out is that it is designed for wide-field imaging. The cameras on telescopes can often only detect objects in a very small patch of sky. If we use the size that the full moon appears in the sky as our guide, Hubble’s field of view is often smaller than that —meaning each picture it takes is of a patch of sky smaller than the full moon. Webb’s instruments often are even smaller than Hubble’s. Each picture taken by Roman, however, will be larger than the full moon, allowing it to survey more of the sky much faster than Hubble or Webb.&quot;<p><a href="https:&#x2F;&#x2F;science.psu.edu&#x2F;news&#x2F;ask-expert-will-roman-help-reveal-long-kept-secrets-universe" rel="nofollow">https:&#x2F;&#x2F;science.psu.edu&#x2F;news&#x2F;ask-expert-will-roman-help-reve...</a>

      And yet the narrow-field Hubble produced this famous image<p><a href="https:&#x2F;&#x2F;science.nasa.gov&#x2F;mission&#x2F;hubble&#x2F;science&#x2F;universe-uncovered&#x2F;hubble-deep-fields&#x2F;" rel="nofollow">https:&#x2F;&#x2F;science.nasa.gov&#x2F;mission&#x2F;hubble&#x2F;science&#x2F;universe-unc...</a><p>Those are galaxies. In a field of view &quot;about 1&#x2F;13th the diameter of the full Moon.&quot;

        Your point being?<p>Hubble in certain circumstances can see narrow and far. If you express this as a cone, you can extrapolate a volume.<p>It might be very useful to have something that can search wide and maybe not as far; nearer Earth dangers perhaps. Express that as a wider cone and extrapolate volume.

      Is it really 500 Mbps of data headed to Earth 24x7? I&#x27;d be very interested to see any available public info about the earth station infrastructure being set up for that.

      &gt; except The Habitale Worlds Observatory Space Telescope HWO was scheduled for 2040 and now will not happen in my lifetime because DOGE got that one, Congress awarded it $150 Million and DOGE changed it to $5 Million<p>I was so excited for this. It was the one thing I really wanted to see happen in my own lifetime.<p>What a deeply moronic waste.

      It is not 500mbps but 500Mbps. <a href="https:&#x2F;&#x2F;science.nasa.gov&#x2F;mission&#x2F;roman-space-telescope&#x2F;communications&#x2F;#HGA" rel="nofollow">https:&#x2F;&#x2F;science.nasa.gov&#x2F;mission&#x2F;roman-space-telescope&#x2F;commu...</a><p>500 megabits per second works out to 54 terabytes per day. No idea where you get 1.5, unless you were thinking of 500Mb&#x2F;hour!<p>60 × 60 × 24 × 500 × 1000000 ÷ 8
