@Steven Pietrobon, I agree VLS-1 belongs on the 100% failure rate list. But is it confirmed that Super Strypi will not launch anymore? (sorry for goeng of topic)

I've been wrong on some thing.
VS-43 in PNAE 2005-2014 is a single stage S43 sounding rocket. The upper part is most likely the ESA/Airbus MAXUS payload system.

I also got the impression that Germany is developing much of the technologies for VLM-1. link
OHB/MT Aerospace have developed a new production method for composite solid rocket casings. In OHB's 2015 annual report on page 71, it is reported that MT Aerospace will start a project in 2016 funded by DLR. For this project MT Aerospace will develop and build three solid rocket casings, most likely S50 stages. They will be used for testing the Brazilian VLM-1 launcher. It also states that the engine test is planed for 2018. (in the 3Q report it was stated that the S50 engine would be tested at the end of 2017. And the dimentions of S50 were  stated a 1,45m diameter and 5m boss to boss length.
I also found out that DLR has funded studies for a hot seperation system for the S50 stages (2th stage burning before seperation). And DLR has been studiing a hybrid upper-stage for VLM launcher.

There could be a possibility that MT Aerospace will build the S50 Casings. Brazilian companies/government will build the nozzle (and possibly igniter) and execute the fuel loading operation in Brazil. For launches from Europe the loading operation can take place at AVIO (Italy) or Nammo (Norway).
I think DLR will continue the VLM-1 development without Brazil when Brazil's funding and progress stalles the launcher development. DLR and ESA need the VS-50 and VLM-1 to execute launches of some suborbital technology development flights. (MAXUS sounding rocket, Expert, SHEFEX III, and possibly some HyFiRE sounding rockets).

I think the VSISNAV (altitude control system test) flight, that was planned for the second half of 2017, can still take place around this time. It will most likely launch on a VS-43 (S43) or S43-S44; S43-S40; S43-S40-S44.
For Brazil it might be interesting to develop composite replacements for the S30; S40 and S43 after the S50 development has been completed. Possibly OHB/ MT Aerospace will allow a Brazilian company to use there technology, or they might set up a Brazilian business unit for this. We shall see.

I believe that they don't know which kind of support they are going to get. But Dilma's was the all time lowest. So they will just stay un survival mode until a new government settles and actually makes a decision.

Detail about VLM and it's planning in the OHB 2016 first quarter report, page 18.
All already known but nice to have an official source for the information.

Edit: I also found this document about SSC project Rainbow form the 32th Space symposium. The VLM-1 launcher will be the base line for the SSC (esrange) Sun-synchronous express launch service. In 2016 they will do the B2 phase flight safety risk assessment. They hope to have the service operational in 2020 with one to three launches annually of 100-150kg to 500-600km SSO. They want a launcher that has flown three successful flights. Besides the solid's it is only allowed to use use green propellants (ECAPS (ADN-liquid) or HTP liquid or hybrid), not hydrazine and NTO. The launcher has to be operational at temperatures as low as -20 deg. Celsius. 
I think Nammo North Star, PldSpace Arion 2, Leafspace Primo, SpaceLS Prometheus 1 and Horizons Black Arrow 2 might be contenders to VLM-1 (or S50-S50-European upper-stage).

Interesting post on cyclone4.blogspot.nl .
A S50 stage might be test fired in January 2017.
A VS-50 sounding rocket (most likely a single stage) might launch during November.

VLM-1 was excluded from the 2016 micro launcher list. (Actually not, ssc: sso express) But in my view VLM-1 is one of the most  rigid supported micro launcher developments, being backed by two or three nations.

So my previous post was wrong. The static test won't happen before the end of 2017.
But tests will happen. On the 23th of December on brazilianspace.blogspot the following news was posted:
The contract has been signed to produce 6x S50 casings.
- Two will be used for pressure tests.
- Two will be used for ground static firing tests
- Two will be used for two VS-50 (S50-S44{most likely} rockets)
And there is an option for two S50 stages can be use on the primary launch of VLM-1 (S50-S50-S44).
This will happen in the coming 26 months.

So they can't keep the development schedule, but there is progress on the VLM-1.

There are a lot more interesting post on this website. A more resent post is about the reason why VLS-1 was terminated (and most likely also VLM-Alfa). The Inertial Navigation System (SISNAV) will be developed using the VS-43 sounding rocket. This is most likely a single S43 stage, from the stockpile manufactured for VLS-1 flight.

The L75 engine developed in Brazil has been test fired in Germany. I think Brazil has the technology to build a family of orbital launchers. What lacks is the political willingness to spend lots on the launchers development.

I hope the VLM-1 will progress and become operational. I think the VLM-1 will form the upper-bound of the micro satellite launcher cost for Europe. I'll explain on request.

VS-50 PDR has taken place.
A lot is under discussion in Brazil, they want a VLM launch before 2019.
I also stumbled accross this DLR MoRaBa page that shows VS-50, VBS-43 and VLM-1.
My guess is that VBS-43 is a S43 with thrust vector control. Nice short term replacement for the Castor 4B in Maxus sounding rocket program.
I don't think US DoD likes this at all.
I like the possible suborbital/ hypersonic science that could be enabled by these three rockets.

What happened to the ASTER Mission?
Hello reader!

Last week I was asked by one of our readers as they were fantastic development activities ASTER Mission, this mission coordinated by the Universidade Estadual Paulista (UNESP), in partnership with the INPE and various other research institutions and universities throughout Brazil that aimed to take the triple asteroid system "2001 SN263" the first brazilian space probe deep space."

Interesting video that show the evolution of aerospace of brazil and talk a little of VLM-1  :o :D






Brazil wants to invest the money it gets with renting its Alcantara base in its space program ...

http://brazilianspace.blogspot.com/2018/09/governo-quer-usar-recursos-obtidos-com.html

It also continues to develop the VLM-1 with the German collaboration ... and it seems to be a mysterious project "Project VL-X" that I did not know if it was a major evolution of the launcher?

http://brazilianspace.blogspot.com/2018/09/ola-leitor-s-egue-abaixo-uma-nota.html

And it seems that the defense will finance the first Brazilian missile ... that has its spatial implications ...

Last month, the Aeronautics and Space Institute (IAE) tested the S50 mtoor casing to the rupture point (hydrostatic test). The S50 motor will be used on the VS-50 vehicle and VLM-1.

So lets kick off the speculation and discussion on the VLM VLX/Aquila launchers.
It's known what VLM is. It's a three stage all solids small launcher. VLM: S50-S50-S44m.
S50 is a new solid rocket motor containing 12mT of solid propellant and a CFRP composite casing.
S44m is a solid rocket motor containing 0,88mT of propellant. It was developed for the VS40 and VLS.

What could VLX/Aquila 1 be. I think that on VLX/Aquila1 the S44m is replaces by a liquid (?bipropallent) stage.
From older presentations Brazilians have been developing four different liquid engines L5, L15, L75 and L300 (kN thrust).
They have test-fired L5 and L75. So I think fir VLX there are two options:
1) S50-S50-L5 (a VLM with S44 replaced by L5 liquid upper stage, weighing ~1mT)
2) S50-L75 (Both the S50 second stage and S44 stage replaced by a 10-15mT second LOx-CxHx second stage ~75kN.
I think there most likely VLX is the first one. The L5 could later be supplemented by the L15 for the VLX/Aquila 1E.

(I was bold enough to change the topic title.)
Edit to add:
It's also known that there were plans for a L300 (4x L75). Let's add some other launcher options with this:
3) Aquila 2? L300-L75-L15, or a two stage L300-L75.
4) 2xS50-L75-L15. (the S50 are side boosters of a overweight L75 core).
5) L500-L75 (7xL75 - L75) with optionally a L5/L15 upperstage.
Then there are also other solid options:
6) 2xS50-S50-S50-L5/L15 (assumed by Brazilspace blogspot)
7) 2xS50-S50-L75 (+L15)
But hopefully Brazil keeps their focus on one project plan, and successfully executes it.
I'm curious what you think VLX is!?

The continuity of the Microsatellite Launcher Vehicle (VLM) is guaranteed, and the introduction of the launcher Aquila I and Aquila Ie (VLX Family), different from each other by the weight they carry and the altitude at which they arrive, is guaranteed.
The "VLX" family will consist of three stage launchers, ie three S50 engines in the first stage (two sides), another S50 driving the second stage and a liquid propellant rocket engine as a third stage.
The load capacity would be around 300 to 500 kg (or even more), depending on the height and orbit to be achieved.
According to Brigitte Verissimo (update), the next vehicle after Aquila 1 will be called Aquila 1e (e = enhanced) and not Aquila 2. The Aquila 1e will have an upper stage the pressurized liquid propulsion and will not be used the L-75 engine . The capacity of this stage has not yet been defined.
This new family will not make the VLM-1 project unfeasible, according to Brigadier Vital, as it is necessary to qualify the S50 engines in flight, among other things.

...

The VS-50 is a vehicle with 12 meters of compliance, 1.46 meters in diameter and mass estimated at 15 tons.
It has, in its first stage, an S50 engine and, in its second stage, an S44 engine, previously used in VLS-1.
For the VLM-1, a second S50 engine will be added. They will make up the first and second stages of the rocket and the S44 will be the third.
The S50 engines are in production at Avibras Aerospace, through a contract signed with the Foundation for Support of Space Science and Technology Research Projects (Funcate).
In the contract is planned to build six engines, but there are already set for the purchase of two others to complete the mission of launching the VLM.
Thus, in anticipation of scenarios, the CDPEB created a working group to deal with the VLX, successor to the VLM, configured to use two S50 engines laterally as booster.
