And one of the companies in this list has actually pulled a tiny launch stunt

Zero2Infinity, seems like ~toy-sized prototype, but hey it launched at 25km altitude, actual hardware even if subscale, and apparently validated a bunch of operational stuff.

So I guess a round-up summary of small launcher developments in Q1 2017 is:


RocketLab have taken Electron vertical and are still promosing a launch in a few months.

Vector have created a test flight Vector-R which they intend to launch on a sub-orbital test flight soon.

Zero2infinity have ignited a [small] engine on their Bloostar vehicle.

Virgin Galactic have spunout LauncherOne development to Virgin Orbit.

Failure of SS-520-4.

Still just under 50 small launch vehicles in development, no signs of serious market consolidation yet (probably because there are also no signs of one company running away and leading the pack).

Now we can count Vector getting off the launch rail.

Rocketlab still only teasing, but presumably they have a lot more total impulse to bring.

Here's a video from Gilmour Space Technologies. Their ERIS launch vehicle (previously called Hyperion) is scheduled for first flight in 2020. They are currently looking at several launch sites, including KSC! They are using a hybrid motor with HTP oxidiser, 3D printed ABS plastic fuel and ceramic catalyst.



They've updated their website and are listing prices for cubesat launches. $900K for 100 kg suborbital to 150 km, and pricing from $25K to $38K per kg for small satellites.

Planning ahead 20-25 years. If Gilmour Space Technologies can make a solid propellant out of an aluminium or magnesium mixture then it can be used to move around the Moon. Lunar regolith contains aluminium and magnesium but very little carbon.

The slide title... "Why hybrid propulsion for cost reduction".   :o ;D That statement by itself is enough for me to discount them. But maybe they can prove me wrong.

Hmmm... I wonder if they're still pursuing cheap turbopumps.
