This Day In Astro History


February 5

2002 - HESSI finally reaches space aboard a Pegaus rocket.  "The approach of the HESSI mission (Small Explorer) is to combine, for the first time, high-resolution imaging in hard X-rays and gamma rays with high-resolution spectroscopy, so that a detailed energy spectrum can be obtained at each point of the image. This new approach will enable researchers to find out where these particles are accelerated and to what energies. Such information will advance understanding of the fundamental high-energy processes at the core of the solar flare problem." The Principal Investigator is Dr. Robert P. Lin, University of California, Berkeley. 

1971 - Apollo 14 Alan B. Shepard and Edgar D. Mitchell made a lunar landing on February 5 in the Fra Mauro formation.

1974 - Mariner 10 Venus Flyby. Mariner10 shows that Venus' clouds whip around the planet in just four Earth days, though Venus itself takes 243 Earth days to make just one rotation on its axis. 

1963 - Maarten Schmidt discovers enormous red shifts in quasars. Schmidt termed 3C 273 a "quasi-stellar" object or quasar; thousands have since been identified.

It is my conclusion that human evolution and the motions of matter in space are intrinsically linked. The observation and understanding of the complexity of biological history on Earth cannot be complete without the tandem observation and understanding of a dynamic greater cosmos. - SpaceGene
