Of course, projecting launch with a resolution of less than a calendar quarter, or even a year, seems like a false precision for something as complex as a first launch
23. The schedule you develop will seem like a complete work of fiction up until the time your customer fires you for not meeting it.27. (Varsi's Law) Schedules only move in one direction.
A helpful boost or "thumb on the scale"?
Exceptions are when there's some sort of barrier to entry or commons issue or something of the sort that interferes with the natural functioning of a market, or where the government itself has a need for a service for which there is limited or no commercial market.It's not clear that any of these exceptions apply in this case.
Bloostar / zero2infinity put a new website up today. They think they'll have significant advantages over pencil shaped rockets. Presenting at IAC2015 toohttp://www.bloostar.com/bloostar/#title-advantagesIn other news, responsive web design single page marketing websites for all startups continue to suckhttps://twitter.com/katrobison/status/654659932726280192/photo/1https://twitter.com/MarcKBoucher/status/654629673792614400

This may limit there ability to hit launch windows.Not sure how they plan to handle boiloff during the ascent time.
August 18, 2003- The standard SXF is to carry 1400lbs to LEO, the heavy lift version is to carry 4500lbs.- A standard SXF launch is expected to cost $6M, and $10M for heavy version. - He believes there is a market for a $6M launch vehicle. - SpaceX currently has 30 full-time employees, 15 part-time/consultant employees (30 = 5 techs + 22 engineers + 3 non-technical). a lot snipped
Today I came across this site: Leafspace Primo .Italian company Leafspace has plans for a 2stage hybrid launch vehicle capable of launching 50 kg (~100lb) to 700km polar. The vehicle will weight 6,4 ton (1000kg) at liftoff (GLOW) and a launch is de supposed to cost 2mln. Euro.

Have you seen any external references, articles or mentions outside of their own website? The site itself is pretty light on detail, although i did spot that the core team members come from Skyward Experimental Rocketry student association in Milan ( http://www.skywarder.eu/blog/en/ )

From 2008 to 2010 DLR, CNES and INTA investigated different concepts for nano-launch vehicles (Aldebaran). The vehicle from s3 was one of the concepts investigated. The program had a clear cost goal:Payload to leo mass: 50kg <2,5 mln euro ~ 3mln dollar150kg <5mln ~ 6mln300kg <7mln ~ 8mlnI think we can add 10kg <1mln ~1,2mln
The problem is in the "rough" conversion:"vehicle will weight 6,4 ton (1000kg) at liftoff (GLOW)"The original site states only 6.4 ton. Assuming SI units as they used everywhere else, that is 6.4 metric tonnes, or 6,400 kg — not 1,000 kg.Like Sheldon said, blame it on Jimmy Carter . . .
Sorry for the confusion. With: ton (1000kg) . I tried to explain the unit, ton. So 6,4 ton = 6.400kg ~=12,800.lbs. {nitice the difference in the purpose for: '.' and ',' between the metric and imperial system}It's a all confusing. I forgot the name of te mars mission that failed. ;p
