Harry C. Holloway resigned from his post as NASA Associate Administrator for the Office of Life and Microgravity Sciences and Applications. Holloway was the first person to hold the appointment after Administrator Daniel S. Goldin created the position in March 1993. Holloway planned to return to the School of Medicine at Uniformed Services University. During his tenure, Holloway had established programs to conduct experimental studies in orbit and instituted the strategic plan for the Human Exploration and Development of Space. Holloway had been instrumental in strengthening ties between NASA and the National Institutes of Health, overseeing the signing of 10 agreements between the two agencies.
At the High Energy Astrophysics Division of the American Astronomical Society, astronomers working with NASA's Rossi X-ray Timing Explorer (RXTE) spacecraft announced the discovery of the fastest vibrations ever recorded in a star system. The vibrations occur when massive neutron stars begin to die out, expelling the outer layers of their solid crusts and creating powerful x-rays. The astronomers working with the RXTE recorded x-rays flickering at up to 1,130 times per second. Scientists were unsure why this process occurred. According to NASA, "the possibility that the RXTE has detected actual waves in neutron stars or a very fast rotation period of one such star is of great scientific interest.
