No ITAR?

ITAR is a US regulation.

ITAR is explicitly designed to prevent unsanctioned knowledge transfer. This includes preventing US companies from integrating their technologies (or payloads) with companies or governments outside the US. It's very much a one-way street unless you have huge amounts of time, money, and patience to deal with it officially, which effectively pushes out small startups. It's a fair bit easier for non-US countries to legally get their payloads launched by US companies.

In that sense, there is barely any legitimate competition between Chinese and US smallsat launchers - I really still fail to understand where these companies get these ideas that Chinese rockets will in any way impact US prices. Any pricing pressures in this case are basically an economic placebo (not really a bad thing if it results in lower launch costs, but still extremely artificial). Chinese rockets simply are not stealing payloads from US launchers.

ILS and ISRO are a totally different story, but they're not mentioned here. It really is just a bunch of baseless "boo00O00OO CHINA!!!!" bandwagoning when you get down to brass tacks. There's no real argument or empirical evidence provided, just your run-of-the-mill self-contradiction, nationalism, and jingoism.

The issue is that in the small sat payload class for these launchers, the customers are both much more international and more able to build their payloads without any ITAR or EAR controlled technology from the US which means that they can then launch on Chinese launchers.  The competition won't be for US payloads but international ones.

For some reason, FutureSpaceTourist's Astra Space topic was locked, so I'll post this here. Chris Kemp, CEO of Astra Space (AKA "Stealth Space Startup") will be on a panel at 2018's Space Tech Symposium in Berkeley, CA. His panel is 6:45-7:25pm PST, April 30.

We already had a thread for Astra, that got turned into a launch thread even though it was the only thread.  At some point I'll either split up that thread into a launch thread and a general discussion thread, or after the first test launch I'll just remove the launch details from the thread title and it can go back to being a general thread (I really don't think we need a separate launch thread for this first suborbital test).

And another short video from the "Launcher" control room for their test stand.

Launcher is currently hosting a livestream for an Engine-1 test firing. Expected in less than 15 minutes.

https://www.youtube.com/channel/UClpfWREerz8Xdt-UNJHeJ5A/live

Watch live from our test site a static fire attempt of Launcher's 3d printed Engine-1 (E-1): LOX/RP-1, regen chamber, 500 pounds-force of thrust, Augmented spark igniter (GOX/RP-1), all 3D printed in three Inconel 718 parts. Whats' new: Updated chamber design with improved cooling.

EDIT (5:25 EDT): Now "probably 10 minutes away."

EDIT (5:32 EDT): T-45s

EDIT (5:34 EDT): Successful test! 30 second run, max (mentioned) chamber pressure 280 psi.

EDIT (5:43 EDT): Max chamber pressure 281 psi. Max thrust 1775N. This view of their command and data reporting software is crazy cool!

Goal is a pump-fed, 22,000 pound thrust engine in the next three years.

I just came across the archived stream and I am in love. It's absolutely flawless rocket porn, basically an uncut and uncensored tutorial for hot-fire testing a fairly large 3D-printed rocket engine. The team cohesion is also fascinating and deeply satisfying.

Can't beat that countdown poll. "Louis?" "Go." "Max?" "Go."

Incredibly impressive work for a 3-man team. The whole thing was gorgeous.

Here's the archive link:

And yet another launcher company to add in the list: Pangea Aerospace. Recently created, in 2018. It is funny because they look like youtube channels, everybody is copying from everybody. Check what they have in their website: "To lower the cost for accessing space for the small satellite market." Totally never heard motto.

Some examples:
Firefly: "Firefly was created for one simple reason: provide economical, high-performance space launch capability for the under-served small satellite market"
Horizon SAS: "Horizon will provide reliable space access at the lowest cost possible"
Generation Orbit: "[...] space launch systems designed to lower costs, improve responsiveness, and increase overall mission flexibility."
Zero2Infinity: "We are building a brighter future in which access to Space is frequent, affordable, secure and reliable for everyone"
PLD Space: "PLD Space [...] is developing launcher technologies to provide suborbital and orbital commercial launch services, dedicated to small payloads and small satellites."
MISHAAL: "Innovative. Flexible. Cost-Effective."
Vector Space Systems: "Advanced small payload delivery system providing fast, efficient and frequent space access."
Launcherspace: "A team on a 10-year journey to deliver small satellites to orbit."

That is a lot of good news. Gradually getting through the presentations.

Has anybody heard about these Aevum guys? Airlaunched, completely new airplane design as far as I can tell. Supposed to start launching next year. Are they for real? Their segment starts at 1:38

Their site mentions a ground test of a subscale vehicle and tests of subsystems already done, but it's also very heavy on the feelgood stuff. Not to be a cynic, but that always makes me cautious. How have these guys managed to stay under the radar if they actually tested all their subsystems?

The presentation is quite inconsistent as well. Their mission is to improve communications and internet. But they want to achieve this by creating a launch vehicle that incidentally allows payloads to launch at 1100$/kg?! Not by designing the satellite network themselves. And actually, it's the autopilot of the airlaunch vehicle they're designing. They're not vertically integrated, so I assume the airplane and rocket themselves are built by contractors?

Unusually, they're apparently not looking for money. Which is the only reason I'm not quite sure what to make of them.
