By early 1975, the date had slipped to March 1979. Funding shortfalls were to blame, as were the daunting engineering challenges of developing the world’s first reusable orbital spaceship based on 1970s technology. The schedule slip was actually worse than NASA let on: as early as 31 January 1975, an internal NASA document (marked "sensitive") gave a “90% probability date” for the first Shuttle launch of December 1979.<br /><br />In October 1977, Chester Lee, director of Space Transportation System (STS) Operations at NASA Headquarters, distributed the first edition of the STS Flight Assignment Baseline, a launch schedule ...

For the first time, scientists are able to directly study the formation of a planet at a very early stage. Observing time at the European Southern Observatory (ESO) on Paranal Mountain is a very precious commodity – and yet the Very Large Telescope (VLT) in Chile spent an entire night with a high-resolution infrared camera pointed at a single object in the night sky. The data collected by the Naco optics instrument enabled an international team headed by ETH Zurich’s Sascha Quanz to confirm its earlier ...
