Here's a link to video of the assembly of the first VLS in launch pad. (Operação Salina)



Congratulations to IAE and its technicians, excellent work

If the Brazilian government was more seriously we would have put a satellite into orbit.
But the government is giving funds to Ukraine (Cyclone 4), this project is a joke.

Came across this:

BrazilianSpace: Lançamento do Foguete Falcon-9 Com o Cubesat AESP-14
   
Vídeo do lançamento bem sucedido da missão “Falcon 9 - SpaceX CRS 5”, missão esta de suprimento para a Estação Espacial Internacional (ISS na sigla em inglês) que também levou a bordo o Cubesat Brasileiro AESP-14 (o segundo canarinho brasileiro) do Instituto Tecnológico de Aeronáutica (ITA).

O lançamento ocorreu as 4:47 da manhã (horário local) do dia 10/01/2015 da Base da Força Aérea Americana em Cabo Canaveral, na Flórida (EUA), e segundo o que estava previsto a nave Dragon da SpaceX com os suprimentos para a estação e o Cubesat AESP-14, deveria iniciar a sua trajetória de aproximação da estação e posterior atracagem a partir das 4:30h (horário local) de segunda-feira (12/10/2015).

Vale lembrar que após a chegada do AESP-14 a ISS, o mesmo deveria ser transferido para o Módulo Japonês Kibo, de onde então em data ainda a ser definida (naquela época) seria finalmente lançado ao espaço através do dispositivo de ejeção “JEM Small Satellite Orbital Deployer (J-SSOD)”.

A colleague was recently at a science conference in Brazil and heard a presentation about a Brazilian asteroid mission that is supposed to go to a trinary asteroid. He said it was an impressive presentation and they are talking about a 2020 launch. However, the spacecraft would go on their own rocket and I explained to him that their rocket has been repeatedly delayed, so any plans that would use it are really tenuous.

He did say that apparently they have a Russian satellite bus that they have modified. Dunno if they showed photos of their spacecraft or anything.

It's not going well with the Brazillian Space program!
Some news from brazilianspace.blogspot: (I use translate to read it)
Three reports about the failure of the VS-40 from last november 1 2 3 . Still there is no report on the root cause, if I'm not mistaken.
Than about the Multi-Year Plan 2016-2019 and the budget for 2016.

The space budget for 2016 was reduced by 39% to 183,8 million. This is in sharp contrast to all goals set for the 2016-2019.

Now over to desktop-engineer talk. I think VLS-1 will never fly again, it has never fulfilled a successful launch so in my opinion it didn't come out of development phase. In my opinion it has to many stages and to many staging events. I've thought a bit about different launcher configurations that can be made with stages Brazil has developed or is developing. I came up with the following alternative.

Until the end of 2017 solid propulsion engineers will be occupied with the development of the S50 stage in a SeaLevel and an Upper-stage variant. Test bench qualification is planned for January 2017 and the qualification flight of the S50 as VS-50 sounding rocket is planned for november 2017.
I think the S50 can be used in four sounding rockets; the VS-50 (S50), VS-54 (S50+S44), VS-55 (S50+L5) and VSB-50 (S50sl+S50u). (The VS-55 is I think the least likely)

For orbital launchers I came up with also four versions:
VLM-1 three stage solid rocket launcher composed of the S50 (Sea Level), S50 (Upperstage) and S44 spin stabilized upper-stage from the VS-40. The test flight for VLM-1 is planned for November 2018, after a couple of flights the inertial navigation system (VSISNAV) can be tested on VLM-1 (or VLM-2) in 2019.
The VLM-2 is composed of the S50sl; S50u and the L5 upperstage. (2019?)
VLM-2+ or VLM-2B, Possibly the performance of the VLM-2 can be improved by two non-separating boosters S40 stages. Possibly a composite version of the S40 can be developed after 2017 (so it can be produced on the same fabrication line as the S50 stages). The VLM-2+ will be a three stage system: [2xS40 & S50sl] + S50u +L5.
Possibly the combo [2xS40 & S50sl] is powerful enough to launch a L75 stage, otherwise the VLM-3 will be composed of 2x (to 4x) S50sl side mounted at the inter-stage and lower-skirt to an central S50u (that is ignited in-flight) and a L75 on top. The VLM-3 is supposed to fulfill the requirements where the VLS-Alfa would be developed for.

For the VLS-Beta I hope Brazil and Europe can reach a agreement where Brazil is allowed to use (and fabricate) the Zefiro 40 (that is being developed for the Vega-C) in both a SeaLevel and an Upper-stage version. (The SeaLevel version is not jet planned). The Z40 can be used to fulfill the requirements of the P40/P50 stage of the VLS-Beta.
It can be used as the current plan for VLS-beta: P40+L300+L75 or as P40+Z40+L75.
The Zefiro 40 can be traded for the S50 stage, so the stages that will take off from Esrange or Andoya can be fabricated in Europe (Germany or Italy). For solids transportation is really expansive because they are explosive/ dangerous goods. If S50's would ever be used for launches from CSG I would prefer them to be build in Brazil.
(I'm for the policy: Design globally, Build locally)

Is this a beter/ less risky and cheaper development approach than VLM-1, VLS-1, VLS-Alfa and VLS-beta.
VLM-3 would not happen before 2020 as is VLS-Beta. Or is this pure nonsence form an idiot behind a desktop.
         
edit: I also think Europe will stop importing S30 and S31 stages form around 2020, because green european alternatives are available. (PLD space Arion 1; Nammo UM-2/ NorthStar Aurora)   

edit 2: It is rumered the SSC (Swedisch Space Corporation, the company that exploits Esrange) will build two launch sites for VLM, one at Esrange, Sweden and one at Maranhao (CLA), Brazil. I hope for SSC is allowed to modify the VLS-1 launch site at CLA (Alcantara Launch Center). And both launch sites to be compatible with at least all four VLM versions and possibly the VS(B) sounding rockets. For VLS-Beta a new launch site would be needed, possibly also for VLM-3/VLS-Alfa.

A new article with a link to presentations from the public hearing was posted on BrazilianSpace.blogspot
here the link to the presentations

Two new milestones with dates were reported in the DCTA presentation:
- The electrical / electronic system mockup of VLS-1 should be ready by May 2017
- The VLS-1 VSISNAV (altitude control system test) launch is planned for the second half of 2017.
- And as already known the first launch of VLM-1 is planned for the end of 2018 (november).

The writer of the blog is skeptical, I think it is a feasible timeline, although their budget is tight. I hope they will be successful and wish DCTA the best of luck achieving these milestones.

Are they going ahead with VLM, jumping to something more advanced, or opting out entirely?

I think the decision to stop VLS is not firmly taken jet. I guess VLM will continue, but also that is not certain. Most likely the launcher program is still in discussion.
The satellite program looks firm (the AIAB PDF, three post back, link Presentation)

My Portuguese is limited, but I understand the below linked press release of April 6th like that:

a) VLS is the programme, VLS-1 was just one launcher configuration developed within this programme (next to VLM, VLS-alpha and VLS-beta)

b) VLS-1 is terminated because it is a design based on the technical limitations of Brazilian industry of the 1980's

c) Development focus will now be on VLM(-1)

At risk of drawing the Mods ire, I'll ask...

In view of today's WSJ front page headline, is this program bound up in the current Presidential political troubles/drama?

Mods: If I've overstepped, please be gentle...

Dilma's administration has been extremely anti-space. I don't think that if the impeachment actually goes through, it will be worse than the current lack of financial support.
Let me state it more clearly. The Brazilian space program main limitation is an absolute lack of budget and political will.
Please remember that Brasil has the GNP and population of Russia. And their program is even less developed than Argentina's.

So it has been confirmed that VLS-1 launch vehicle (4xS43+S43TM+S40TM+S44) will not launch again.
They came together to discuss the results of the VS-40 failure.
But nothing was written about what exactly happened, or did I miss it.

IAE also proposed the development of a VS-43 sounding rocket.
This might be an indication that IAE wants to stop using the S43 stages.
This would meen that VLS-Alfa (4xS43+S43TM+L75) would not be realized.
Possibly they change the design to S50 stages (possibly: 2xS50+S50+L75).
Another possibility is a liquid two stage system (L300 (4x75)+L75).

I think IAE has a supply of S43 stages for 1 to 3 VLS-1 launches (5-15x S43).
Most with canted sealevel nozzles and some with straight high altitude nozzles (S43TM).
They will have to develop a straight sea-level nozzle. Possibly the S-40 nozzle can be used.

I'm wondering what VS-43 really involves. I think there are three options:
1) only a S43 stage
2) the old VS-43 (PNAE 2005-2014); S43 + S30 
3) Two stage improves VS-40: S43+S44 (or would they name this VS-44?)
I think VS-43 is a method to efficiently get rid of the S43 stages and
supply launchers until the S50 is (reliably) available (not that the VS-43's have a good track record).

The VS-43 might be used for the VSISNAV mission.
A test flight for the SISNAV (autonomous inertial (navigation/guidance) system),
as preparation for use on the VLM-1 (S50+S50+S44).

edit: on this site are some other VLS Cruzeiro du Sul launch vehicle configurations.

Alas, another launch vehicle to join the inglorious rank of 100% failure rate. Off the top of my head, these include Atlas Able, N-1, Europa, Conestoga and Super Strypi.
