Lecture 1: HTRA: history across all wavelengths, with emphasis on space science technology
- From optical photographic to photoelectric photometry at ground-based observatories
- First discoveries in space at X-ray wavelengths, with rockets, then satellite surveys
- Fast timing capabiities of Uhuru, OAO-C, SAS-3, HEAO-1 - all with proportional counters
- X-ray pulsars, bursters
- use of fast timing to provide spatial resolution
- Larger collecting areas of EXOSAT, Ginga revealed QPOs, and (RXTE) MSXPs
- Early detectors for HST, EUVE
