Looks way more professionally-built than others I could mention...

EXOS posted a video to Youtube yesterday of a hold-down firing, using what looks to be a full-size SARGE engine and body.  It's characterized as a "low-pressure test", with a full-power one soon to come, but even at this stage it looks bloody impressive.  As some on this forum have said, others have made much more hype over much less achievement...  https://youtube.com/watch?v=SrkCULVaxGo

They also made a blog post to accompany it, with a lot of great pictures before and after the test (if anyone else wants to attach them over here feel free, I'm on mobile and can't really do so): http://exosaero.com/2017/08/20/tie-test-1/

Gotta love how the test lasted ~30secs.. and then the minions spend the next minute-and-a-half putting out spot fires!!   :) ;D
With sufficient thrust, pigs fly just fine - however, this is not necessarily a good idea. It is hard to be sure where they are
going to land, and it could be dangerous sitting under them as they fly overhead.

Misidentified this initially and was told that it is an EXOS stand and engine :)

Super cool. I love this kind of test of rockets. Between a tethered hover test and a tie-down test, you can get pretty close to actual test flight without a big risk of losing your hardware if things go wrong. Relying more on engine gimbaling than control surfaces also helps address the risk of control inversion as you go through Mach 1.

Good luck!

I'm curious what sort of valves/plumbing you are using for controlling propellant flow to the engine - do you have one pair of fuel/LOX valves that provide start-up flow followed by a seperate pair of main-stage valves, or is it a single pair that can be opened partially? 
I am a member of a university group that is working towards something similar (if a bit smaller), and finding fast-acting valves with fine-grained throttle control has proven rather... difficult.

At #NSRC2017, John Quinn of Exos Aerospace says company on track to get FAA launch license for its suborbital rocket by Feb 14, 2018; earliest launch would be following Saturday (Feb 17).

Looks like a couple of the concrete highway dividers might be good to protect the truck!

I will so love to see them fly again. Armadillo was a favorite during the Xprize and Lunar Lander Xprize contests. Their launches at Spaceport America made it seem they were very close to having a working vehicle.

They blazed the trail with insurance and the FAA.

Good Luck!!

EXOS posted a pair of videos today - the first is a piece on what SARGE does (low-cost suborbital research opportunities via reusable rocket) including a lot of STIG footage, reminiscent of similar videos from other space startup companies.


The second video is more interesting: an actual tie-down test firing of their rocket (it's a 360-degree video, look down ;D ).  Worth noting that the tie-down test in today's video is longer (almost 60 seconds) than their previously released test footage (about 26 seconds back in August of this year).  Also, the August test was called "low pressure", with a "full power test coming soon".  There is no indication that this test was necessarily conducted at a higher pressure, but I wouldn't be surprised if they had expanded the envelope on multiple fronts over the past 4 months.

Just to be clear, it's a suborbital launch license.

Exos Aerospace Prepares for First Suborbital Launch
By Jeff Foust, SpaceNews Writer | March 25, 2018 09:08am ET

WASHINGTON With a key test completed and a launch license in hand, Exos Aerospace is preparing for the first flight of its reusable suborbital rocket in April.

I was looking around for Exos on the internet and I came across this website:

https://www.theapeirongroup.com/

that mention Exos in their partners and space section (and also their education section is from Exos as well)

has anyone heard of this company before?

Exos have quietly replaced the launch countdown on their website with this notice;

Launch has been postponed. A new date will be announced soon. Stay tuned.
