Mission Notes

Spaceflight and industry

Mission Notes follows the business and engineering of spaceflight. Rockets, satellites, contracts, and the industry behind the missions. Space Daily has reported on this beat since 1995, when the launch industry was a fraction of its current size.

Engineer's placemat sketch became America's first spy satellite

The placemat, the 600-mile figure and the real cover experiment all come from the National Reconnaissance Office's own history of Grab and its successor Poppy. No footnote in that pamphlet ties a statement about Grab to a specific record, two of its figure references point at the wrong launch, a third disagrees with its own text on a date, and its claim about being first is narrower than it looks in summary.

Declassified 1959 Army plan proposed Moon base from Brazil launching site by 1966

Project Horizon was paid for out of an office's existing budget, because the general who ordered it wrote back that no new money was available, and delivered just under twelve weeks later in two volumes. By March 1960 it had been passed to NASA. Most of its arithmetic is still legible, and where it can be read it matches the summary the Army now publishes on the cargo but not on the rockets.
