RobGoldsmith sends word of Interorbital's TubeSat Personal Satellite Kit, which allows anyone to send a half-pound payload to low-earth orbit for $8,000. Your satellite will fly to orbit from Tonga atop an Interorbital Systems NEPTUNE 30 rocket along with 31 other TubeSats. It will function for several weeks, then its orbit will decay and it will burn up in the atmosphere. Interorbital plans to send up a load of 32 TubeSats every month. If you pay in full in advance, you get slotted onto a particular scheduled launch. Here are Interorbital's product page and brochure (PDF).

The sign that a technology has really matured enough to be taken seriously is when it starts to have commercial applications. Moreover, the presence of businesses like this will help provide further incentive for the improvement of space related technologies.
However, it isn't clear to me who would use a half-pound satellite that can only last a few weeks. TFA lists the following possible applications:
Earth-from-space video imaging. Earth magnetic field measurement. Satellite orientation detection (horizon sensor, gyros, accelerometers, etc.). Orbital environment measurements (temperature, pressure, radiation, etc.). On-orbit hardware and software component testing (microprocessors, etc.). Tracking migratory animals from orbit. Testing satellite stabilization methods. Biological experiments. On-orbit advertising. Private e-mail
Honestly, I don't see much use of most of those as a general use. Certainly scientists will benefit from this sort of technology but I doubt anyone would try to use this for private e-mail systems. You would just use the internet and encrypt your stuff. The idea of using this sort of thing for low cost climate and weather data gathering is interesting. I suspect that as with many technologies, new uses will be developed that we cannot easily anticipate now that the technology is still young.
Not really. Our best plan for artificial weaponized meteors is telephone-pole-to-crowbar sized rods of tungsten [wikipedia.org]. Somehow I doubt that much tungsten weighs less than 0.5 pounds.
I understand that the volume is currently small, but they are commercializing the burn-up of potentially hazardous material in earth atmosphere. Circuit boards contain many things that shouldn't be burned. I hope that they screen for hazardous material that shouldn't be put into the atmosphere.
This river running next to my factory is huge, and the sea it runs to is even bigger... so who will notice if I dump a barrel of waste arsenic in that river?

It says you can link up to four together at a time. I guess the first unit would have the antennas, thrusters and deployment, with up to three separate payloads.

Isn't the cost to put junk in orbit through existing channels just 2000/pound? That puts this at 16 times the existing rate and you don't even get a stable orbit.

32 satellites at $8K each is only $256,000. Subtract the cost of the materials used to build the satellites. (I'm assuming they're not using class S parts, but solar panels, etc still ain't cheap.) They're seriously planning to deploy a working delivery system to space for that kind of money?
If you figure it costs about $10,000/lb to launch stuff into space, launching 16 pounds would leave $96,000 for administration and profit. The numbers are plausible. And if they start launching from a Virgin space plane, then the launch costs could do down dramatically.
They seem to base their ideas on what the OTRAG project tested and worked on in the late 70s. The idea is that the rocket is made up of inexpensive paralell coupled "segments".
The idea behind the OTRAG design was that if each segment where identical, the manufacturing process could be streamlined to a very cost effective level, much like how cars are made.

with equipment that's already gone through R&D, and warrantied against failure during the trip into space, with space for additional cargo of up to 0.2kg. I'm sure they'd sell you the empty casing plus space on the rocket for less than $8 large (maybe as low as 4K? judging from their pricing model, it looks like the 4K is for the actual propellant/overhead costs), but it's going to cost a business a whole lot more than 8K to develop space-worthy electronics + software to put in the canister.
Given that you'd need electronics on board and three thrusters, I doubt you could get a reentry-survivable slug of any appreciable mass up there under this program.
Still, its neat to think about wiping my enemies out with artificial meteorites.
How many high pressure CO2 cartridges can you fit in one of those, and would they provide enough thrust to get your device out of earth's orbit? Maybe stick it in a figure 8 orbital pattern between the moon and earth, or shoot it off towards Mars. I would imagine you need substantially less thrust to break from earth's orbit for a lowly half-pound payload than say, a space shuttle, not to mention, the pressure differential is substantially greater.
Hmm I looked at this some more. It looks like there is only a 2,900 joule requirement to leave earth's orbit from LEO for a 1kg object. So you're looking at 1450 joules to leave earth's orbit at full weight; a CO2 cartridge provides about 150 joules of energy. You should be able to fit at least three CO2 cartridges in that canister, so you're already 40% of the way to deep space exploration using off the shelf technology! Plus each cartridge uses 12g of CO2, so the probe becomes lighter as it uses it's fuel

Seriously, no. 2.9kJ is nothing. It's less than the biochemical energy in 0.1g of fat, only enough energy to lift 1kg 300m against gravity.
2.9kJ is certainly not sufficient for accelerating 1kg from 8km/s (LEO orbit) to 11km/s (escape velocity) or even just about 10km/s (geostationary transfer orbit perigee).
1J=1Nm=(1kg*m/s^2)*1m=1kg*(m/s)^2
Kinetic energy of 1kg at 8km/s: 0.5*1kg*(8000m/s)^2=32MJ
Kinetic energy of 1kg at 10km/s: 0.5*1kg*(10000m/s)^2=50MJ
That's a difference of 18MJ to get 1kg from LEO to a geostationary transfer orbit (and some more to turn that into a geostationary orbit).
One wonders about this. To orbit some AD HOC electronics package does not sound like a very good idea to me! At the very least, the packages would need to pass stringent EMI/EMC testing, the likes of which would undoubtedly cost more than $8k alone!
Mind you, would be great for making annoying messages to broadcast down upon unsuspecting populations. (I am sure I could easily build a low power TV transmitter + annoying several hours of program material (set to repeat) in less than 220 grams!) (how many 50
Doubtful in that mass budget. You couldn't just stick a thruster on it- you'd need a full attitude control system to make sure you were actually pointed in the right direction, and thruster(s), reaction wheels, etc would pretty rapidly use up all your mass.
Actually, I was really far to tentative with that response. I think the real answer is "no way in hell." Just too much energy that you'd need to store in that half pound somehow.
Remains are one thing, but sending your kid's teeth or whatever to space??
Wait... actually I'll do it for $25/gram. I assure you I will deliver your parcel to "space" --I've got space in my garage, heh-- and you can get the kid a telescope and tell him to look for it. No need for a wasteful rocket launch. I get paid, the kid gets a thrill and you get plausible deniability (I paid to send it to space, I swear!). Everybody wins.
I don't see why this would help. They can jam it like anything else. It isn't as if their jamming methods rely on blocking line-of-sight. And you aren't going to get much power from a transmitter in one of these.
A couple of rockets is piss compared to the millions of cars, factories, and volcanoes in the world. "Straw that breaks the camel's back" is just a strawman (pun not intended:/) argument used by ludites that have something against cool technologies for some reason.
Gravity guns are science fiction, but laser brooms [wikipedia.org] could bring down space junk. You fire a laser into space from the earth, and any space junk in its path gets partially ablated, which thrusts it into a more eccentric orbit, which increases atmospheric drag and makes its orbit decay faster.
I thought that too, until I read further. They don't put it high enough to be remain in orbit.
But of course the day will come soon when they will be able to put it into a stable orbit, and then it will become a concern.
I recently saw a simulation showing all the currently unclassified object being tracked in orbit around the earth. My instant reaction was "how the hell will we ever get another rocket through that lot?" Alien observers must think we are building a metal sphere to hide behind. Bit like a glob
