Nasa Nano Satellite Challenge

11/05/2010 11:15 PM

Greetings All,

Is anybody interested in putting a group together to go after the Nasa-Nano Satellite Launch Challenge?

To make this feasible at less than $10,000 per pound to launch it would have to be done for less than $50k, (both launches, including startup costs), The goal should be to get the price down to as small as possible, like $4-8k.

I have my own ideas how this can be accomplished. The group would require volunteerism, donation (we could each chip in $1k), and skill. I have land and access to open space for launch.

Read the following and tell me what you think?

Repeatability within a time constraint deters one-time stunts that would not lead to a useful launch capability. This is anticipated to be a first-to-demonstrate challenge.

Range safety costs and procedures will be a critical issue for competitors, but some existing and new ranges may offer incentives to attract competitors. The Federal Aviation Administration will have an important role in permitting and/or licensing of competitors.

Hi spacecannon,

I'm interested in your Team proposal regarding the Centennial Challenge to orbit a nanosat. I was hoping that NASA would finally get around to this sort of challenge, and would like to have a go at it. Since your moniker is "spacecannon", are you inclined towards that sort of technology to put a nanosat into orbit? Along those lines, are you familiar with the work of Gerald Bull and the HARP project of the 1960s that fired projectiles into sub-orbital trajectories (I think the maximum height one of his Martlet projectiles attained was around 120 miles altitude). Unlike Bull, who used converted military artillery pieces for his shots, and hence were "one-stage" guns (i.e., a propellant directly fires a projectile from the gun), people like John Hunter (formerly of Lawrence Livermore National Labs -- LLNL) developed two-stage light gas guns in the hope of developing a space launcher. As far as I know, Hunter is actively pursuing an ocean-based light gas gun launcher with a couple of other former employees of LLNL. I think they want the U.S. government to fund it for about a billion dollars.

My point here is 1) are you thinking rockets or guns to launch the nanosats, and 2) if a gun is used to propel the nanosat, then are you thinking about a conventional artillery-type gun, or a light gas gun (which can be either of one or two stages)?
