We were all waiting for this announcement. Arecibo is a science jewel.

Of using X-ray or perhaps gamma ray derived imaging is simply superior
to anything else, not that older technology shouldn't be upgraded as
best possible, unless that cost is simply out of line with what these
new and improved replacements can accomplish so much better imaging
results, and without their having such massive infrastructure to
support.
