DLR STERN - STudent Experimental Rockets program
«

German DLR has a student rocket program named STERN. Student teams have three years time to develop their rocket that flies higher than 5km (16400ft). The student get the opportunity to launch their rocket from (SSC) Esrange, Sweden. More about STERN on the site of DLR

,
MoBaRa
and
Facebook
Last October the first three university teams got their flight opportunity; DLR released a
report
and a
.
TU Berlin
launched two times the upper-stages of their DeCan (Deuche Cansat Hohenrakete | German Cansat Soundingrocket). Both rockets flew successfully to an altitude slightly higher than 5km.
ERIG
from TU Braunschweig launched there hybrid engine powered Faust. Also this launch was successful.
HyEnD
from TU Studtgart launched there HEROS rocket, a 10kN (2248lbs) N2O-Paraffin hybrid rocket that should have reached 20km (65600ft). Unfortunately their engine suffered a failure.
Next April the second flight opportunity takes place, again three teams will get a flight opportunity.
AquaSonic
(HS Bremen) states on their website that their rocket will launch this opportunity.
I could not figure out with other teams will launch their rocket. I have found four other universities that are developing a rocket for the STERN program.
WARR
(TU Munchen) aims to reach 15km (49200ft) with their WARR-Ex 3 rocket.
HyComet
(HS Augsburg) is developing HyCOMET 1 powered by HyER 1K (a N2O PE 1kN (225lbs) hybrid rocket).
TU Dresden
is developing Smart 1 powered by Ethanol-LOx 500N Elbe engine
And
ZARM
(UNi Bremen) is developing ZEpHyR, with a 2kN Hybrid LOx-Parafin rocket it should reach 20km.
In October 2016 is another flight opportunity for two teams. And the SSC launch schedule also shows flight opportunities for three teams in Oktober 2017, 2018 and 2019.
News about the progress these student teams make and discussion about these systems can be posted in this topic.

On the facebook page a link was posted to DLR's 4th Issue 2015 of the Countdown Newsletter. Page 32 to 37 contain an article about the 2015 STERN launch opportunity. link to the
newsletter
I also was funny to find out my post was quoted from on
this
site.

HyEnD released their video compilation of their HEROS hybrid sounding rocket launch, that unfortunately failed last October. It really was a beauty.
Also the link to their facebook page.

The Wednesday, 21 October 2015 report from the link below says "The review and the countdown were successfully and the release it was given us for our launch attempt on Thursday." That makes a launch date of 22 October. From the video, launch time was 14:45:00 UTC.

AquaSonic of Hochschule Bremen and ZEpHyR of Uni Bremen (ZARM) are at ESRANGE being prepared by the respective teams for their launch at the end of this week / beginning of next week.
Updates likely to be posted on the
STERN Facebook page

Tomorrow the first launch attempts of STERN 2016/1 are planned. Two rockets are being prepared by two different teams. The FRR (Flight Readiness Review) for AquaSonic is planned for 8:15 LT (Local Time UTC+2).
The launches are streamed live on
SSC page
and
First up is
Aquasonic
form Hochschule Bremen, with their Aquasonic rocket. It is 5m long, weight 76kg and is powered by a pressure-fed 2,5kN N2O-PE hybrid rocket engine. It is supposed to reach an altitude of 6,2km and have a flight time of 332seconds.
The second team is
ZARM
(from TU Bremen) with their Zephyr rocket. Zephyr should reach a 20km altitude with a 5kg payload. It is powered by a pressure-fed 2kN LOx-Paraffin Hybrid rocket engine.
I wish both teams good luck and a learning-full experience.
PS. In the beginning of may the French Perseus project SARA 2 Rocket will launch from Esrange

If all goes to plan, Aquasonic will launch over 1:50. (UTC+2 LT 13:00; UTC 11:00)
edit:
Not all went to plan. They got to T0 at 13:10, but did not take off. Some smoke could be seen coming from the launch pad. I couldn't find what happened, but to me it looked like the ignition went wrong.
At 14:45 they have a meting. (al times at LT; UTC+2)

Zarm ZEpHyR should have launched today, but the countdown was stoped because the wind was to strong.
Source STERN Facebook.
Countdown will resume tomorrow LT (UTC+2) 4:00. (from the SSC / Youtube live feed.)

AquaSonic had a successful launch Thursday 14-April 2016: 06:00:02 LT (UTC+2) from Esrange Space Center MRL launcher. There are two video's on the facebook page of
Aquasonic
, and the video is shared on the STERN facebook page.
AquaSonic has packed their equipment for transport back to Bremen.
Unfortunately the AQUASONIC rocket has not been recovered jet.
ZARM with their ZEpHyR are still waiting for their third launch attempt. They don't have operations today (Friday).
Both the first and second launch attempts were aborted because of to strong winds. I don't know why they didn't have a launch attempt yesterday (Thursday).
Update:
On the live stream the schedule writes: ZEpHyR CD (countdown starts) on Saturday 09:00 LT (UTC+2)
Most likely the French Perseus team arrives next week to launch their SERA 2 rocket. Their first launch attempt is planned for April 27th. Their live stream is already available. (I won't post it here)

ZEpHyR had their launch April the 16th.
Launch and recovery were successful.
Unfortunately they only reached 1,5km altitude.
Report can be read

HyEnD - HyRES Hybrid Rocket Engine Test 16
rocketman0815
Published on Aug 15, 2016
Test 16 of our 10000 N Hybrid Rocket Engine "HyRES". This was done with the configuration and conditions during our launch in October 2015. As we expected from theory, the combustion is clearly unstable under these conditions and we modified these conditions for the next test 17, which shows excellently stable behavior.

HyEnD - HyRES Hybrid Rocket Engine Test 17
rocketman0815
Published on Aug 15, 2016
Slightly improved version of our 10000 N Hybrid Rocket Engine "HyRES". Compared to last year, we increased the combustion effficiency even further and also the combustion is more stable.
Test 17 with 15 seconds burn time at full thrust. Propellants are Nitrous oxide and paraffin fuel.
Built with funding from the German STERN Program from the DLR. Test site M11.5 provided from DLR Lampoldshausen. To be launched on the sounding rocket HEROS 2 from Esrange, Sweden.

On the website of
SSC
there is a range safety warning for two Heros launches between 28 Oktober and 9 November. On the
HyEnD facebook
page they posted a massage yesterday that the cold countdown test went successful. The launch is planned for Monday or Tuesday depending on the weather at Esrange.
One thing I can't understand. In
DLR Magazin 151
there was a article about STERN 2016-2. The article writes about HyEnD with the second attempt of HEROS, but also about the first attempt for HyCOMET.
Does anyone know what prohibited HyCOMET to execute their launch?
I wish the HyEnD team the best of luck. I hoop they break the European student rocket altitude record. I like a bit of competition between the university teams.

HyEnD HEROS Launch Campaign 2016 - Lift-off
rocketman0815
Published on Nov 1, 2016
We had a successful countdown and lift-off of our HEROS hybrid sounding rocket from ESRANE Space Center on October 31st, 2016. The white box around the rocket is styrofoam for heat insulation of the rocket. Video data shows a nominal flight at full burn time.
At lift-off we lost our telemetry connection. Further data is still being analyzed.
