Succesful Brazilian launch

http://news.bbc.co.uk/2/hi/americas/3948531.stm

"Brazil has successfully launched its first rocket into space. (...)
"At the time of last year's explosion, some predicted it would take
years for the programme to recover.
"Now there is likely to be jubilation that a VSV-30, or Brazilian
Exploration Vehicle, has been successfully launched, also from
Alcantara.
"Sunday's project was a less ambitious one, designed to carry out
experiments just outside the Earth's atmosphere at a maximum height of
250km."

Without wanting to belittle the accomplishment of Brazil, this rocket is
doesn't have a satellite lanching capability, unlike the one which explosed.
It's a sounding rocket.

This was confusing me; most of the reports indicated it was the same as
the one which exploded (and gave capacities roughly consistent with
that), but it did read somewhat like a suborbital launch - and AIUI
they've been doing those already.

Is there much commonality between the two?

Without knowing the details myself too, could this be a partly fueled orbital
design being tested with a sub-orbital flight. After last year's explosion I
don't blame them to try little steps at a time.

PS. Did they find the cause of the that happened explosion last year?

I regard your remark as a logical interpretation of the reports provided
so far as the report did read as if it was a suborbital launch. The report
I read said that it was a two stage rocket and didn't applify as to whether
they had booster solid rockets that weren't considered stages.

I believe they did find the cause of the explosion, something about RF
setting off an igniter or igniters. I didn't read anything about how much
troubleshooting went on.

We just have to wait for more data, if the Brazilians want to
release it.

No. It's two completely different models. The VLS
http://www.astronautix.com/lvs/vls.htm, which explosed, was designed to
carry satellites into orbit ( 120 kg at 750km circular orbit ). The VSV
sounding rockets OTOH are designed for a balistic trajectory which intersect
the earth, carrying a 600 kg load to a 25km apogee. It's still much better
than the previous Brazilian sounding rockets
http://www.astronautix.com/lvs/vs30.htm, but nothing like the VLS would have
been. There's a lot of difference in the delta V required.

Yes. Not following the safety rules and having people working on a live
rocket without taking proper precautions - sparks, on a live rocket.
