This latest milestone comes after “first light” was achieved on Nov. 14. Since then, the system has demonstrated faster data downlink speeds and increased pointing accuracy during its weekly checkouts. On the night of Dec. 4, the project demonstrated downlink bit rates of 62.5 Mbps, 100 Mbps, and 267 Mbps, which is comparable to broadband internet download speeds. The team was able to download a total of 1.3 terabits of data during that time. As a comparison, NASA’s Magellan mission to Venus downlinked 1.2 terabits during its entire mission from 1990 to 1994.

Honestly the 1.2 TB I'm the early 90s is an insanely impressive figure to me. I mean in that era a gigabyte seemed like an obscene amount of data, the interat ran at less than 56 kbps, and I don't think I had a 1GB drive in my hime PC until almost the turn of the millennium. Sending and storing that much from venus is a huge accomplishment.

1.2 Tb* ~ 150GB

Still impressive though

They probably stored it on tape which was slow but could hold an impressive amount of data.

I remember my first multi gig hard drive. I was blown away that I could fully install Diablo 2, Fallout 2, and a cracked version of 3d Studio Max at the same time. No more changing disks!
