It is not necessary to register for an account to search the Archive catalogs or retrieve public data.
However, to retrieve proprietary data, such as recently archived HST data, a MyST account is required.
When retrieving proprietary data through our web form, the Retrieval Options page will ask you to enter your MyST email and password.
This will be used to verify that you are authorized to retrieve the data.
You can also use your MyST account to retrieve public data, instead of doing so anonymously, if you wish.
For questions about the Archive account transition or to request access to proprietary data, please email email@example.com.
