St Kwan's Home for the Terminally ADD: Radiation-pressure propulsion for nano-spacecraft
Abstract: The Breakthrough Starshot project proposes using radiation-pressure propulsion to send multiple spacecraft in the gram-range mass to interstellar targets. There are numerous engineering challenges to accomplishing this mission, but their project discusses speeds and accelerations previously only discussed for cannon projectiles and particle physics experiments. This article examines the problem from first principles to see if the project is even orders-of-magnitude possible. A preliminary check on their numbers seems to confirm that the project is possible in principle.Tue Jul 2 19:45:49 2019 - permalink -

E21 Golf Company Space Shot Three Days Or Three Years In Orbit
New orbit trajectory calculations by Russian scientists contradict NASA's original projections that the golf ball will orbit the earth for approximately 3 days, and suggest a 3 1/2 year orbit is more likely, as the ball will descend by a few yards a day.Fri Jan 19 15:13:09 2007 - permalink -- http://www.spacedaily.com/reports/E21_Golf_Company_Space_Shot_Three_Days_Or_Three_Years_In_Orbit_999.html
