Launch Campaign

The launch campaign of the Stratos III rocket officially began! The rocket will soon be launched from the El Arenosillo launch site in the south of Spain. The team arrived there on the 4th of July to set up the campaign and prepare for the big day. The first launch attempt is planned for the 20th of July so save the date and don’t miss the live stream. Currently scheduled windows are:

18th of July  20:00-00:00 (CEST)   (cancelled)
20th of July 20:00-00:00 (CEST) (first attempt)
24th of July 20:00-00:00 (CEST)
27th of July 20:00-00:00 (CEST)

Press contacts can be found in Contacts. We have a press-kit including pictures and right-free video available upon request.


The goal of Project Stratos III is to break the European student altitude record currently set at 32.3 km. To this end, the team developed the biggest rocket ever made in DARE, propelled by a powerful hybrid engine. It will be launched from El Arenosillo in Spain, where we will be given multiple launch windows. This is because our ability to launch depends heavily on weather conditions and vehicle readiness and thus we need a few launch windows. INTA will make sure to give us 4 launch windows on the 18th, 20th, 24th and 27th of July. We will post the updates here so make sure to regularly check this page if you want to know when we are launching Stratos III. You can also sign up to get an e-mail with the launch date notification here.

Due to very strong winds at the coast, we could not put #StratosIII in the tower during the yesterday's dress rehearsal. Let's hope the weather gods are in our favor for the remainder of the campaign! 💨💨 DARE_TUDelft photo

The launch will take place in the south of Spain, on a launch site owned by the Spanish Space Agency “Instituto Nacional de Técnica Aeroespacial”, or INTA, for short. The facility is situated near the city of Huelva on Spain’s south-western Atlantic shoreline. On the above mentioned launch days, they will ensure a naval and aerial exclusion zone, where sea and air traffic will be banned for safety purposes. They also have equipment to provide tracking during flight and finally perform the recovery of the rocket from the Atlantic Ocean after the flight.


Live stream

The entire launch will be live streamed on our website, as well as the DARE Facebook and YouTube pages. As the lift-off will happen around 20:00 CEST, the live stream will start an hour earlier so around 19:00 CEST. This way, you will be able to watch all of our preparations and launch procedures. When the rocket lifts off there will also be on-board footage so you can see the surroundings of the flying rocket.


How to follow our campaign

We will post daily blog posts about the launch campaign in the News section of our website. There, you will be able to learn all about the Stratos III design, our sponsors, past testing and of course the status of the preparations for the launch and everything that is happening at INTA. Reading our blog posts is especially good if you would like to know all the details about the launch campaign.

Facebook is the social medium we are probably most active on. During the campaign, it will be one of our primary ways to keep you updated about what we are up to, the status of operations, and the most likely launch windows at any point in time. We will also share our website updates here. Liking us on Facebook is therefore a good way to make sure you don’t miss out on anything.

You can check out all our past and newest videos and vlogs on our YouTube account. We will post daily vlogs about everything happening at the launch campaign so you can have a sneak peak of the preparations for the launch. The launch will also be live stream here so make sure to subscribe!

Twitter will be used for minute to minute updates. So it will be most intensively used during the hours leading up to a launch attempt. To make it accessible to a wider audience we embedded it on our website. That way you can also find the latest updates here.
