ESA Television is the television network of the European Space Agency. It is a satellite-only broadcast network which periodically transmits programming via SES Sirius's Sirius 4 satellite to Europe and via SES New Skies's NSS-806 satellite to the Americas as part of the Europe by Satellite public information service. While ESA does not broadcast simultaneously over the internet, it does make programming available for download via an FTP website, which requires users to log in to access material. A username and password is made available by registering for the ESA Television Notification Service.
