The HEASARC and NuSTAR teams are greatly saddened by the sudden passing of Katja Pottschmidt. Most recently Katja was the lead scientist for the NuSTAR Guest Observer Facility (GOF), a role she had supported for many years. During her science career she worked on many other high energy astrophysics missions and played an integral role in advancing our knowledge of the universe. She was a wonderful colleague and friend and will be keenly missed by all who knew her.
How Much X-ray and Gamma-ray Data Are Coming In and Going Out of the HEASARC Archive Every Day?
Last Update: 2018 April 19
As of this date, the HEASARC's high-energy archive is growing about 44 Gigabytes (GB) every day, equivalent to 16 Terabytes (TB) every year.
HEASARC users are downloading about 520 GB of X-ray and gamma-ray data every day, equivalent to about 189 TB/year. This can be compared with the current 100 TB size of the entire HEASARC High-Energy Archive. Thus, in one year the HEASARC user community downloads a data volume 1.9 times the size of the archive.
