» LOTS OF QUESTIONS –
WE PROVIDE YOU WITH THE ANSWERS! «
Since a weather balloon is not launched into the stratosphere every day, most of you will have a lot of questions! We have already answered the most frequent questions on this page. Further answers as well as instructions can be found in our tutorial.
Is such a space flight even allowed?
Yes! Though, to send your camera into the stratosphere you’ll need a permit from the German air traffic control and the Federal Aviation Authority / district government. You can find the contact details of the German air traffic control. Before that, however, a permit from the Aviation Authority responsible for your country is required.
After receiving this permission, you can apply for the permit to launch at the German Air Traffic Control. You can find the addresses of the responsiblefederal offices.
In the first step, it’s best for you to use our Weather Balloon application, which guides you step by step through the registration process.
Do I need an insurance?
In order to apply for the ascent permit, the air traffic control or the aviation authority in some countries also requires proof that insurance is available in case of emergency. The best way is, to get advice from an insurer regarding a so-called “aviation holder liability insurance”.
With hundreds of successful stratospheric flights for various advertising campaigns since 2011, we are one of the most experienced providers of stratospheric flights in Europe. Our equipment has been engineered & tested for reliability and is designed to be very cost-effective, so that almost anyone can launch a balloon into space. Furthermore, we have launched the MINT school project on the edge of space for schools, so that our stratosphere project can make science more tangible for schoolchildren. In addition, we offer a trained high-quality support!
What altitude does a weather balloon reach?
The maximum altitude depends on several factors. The decisive factor is the choice of the weather balloon. Thus, our weather balloon 800 reaches a height of up to 30km, whereas larger weather balloons, such as the weather balloon 3000, reach maximum altitudes of 40km. Basically, the less helium is used or the lighter the total weight, the higher the balloon rises. We have developed a calculator for the purpose of calculating your altitude.
How much Helium/ Baloon gas do I need?
As a rule of thumb, you need 1 liter of helium to keep 1 gram leveled. In addition, you need a buoyancy. For an exact calculation of the required amount of helium we recommend our helium calculator.
What sizes do the gas bottles come in? whcih should i choose?
There are different sizes, e.g. 10, 20 and 50l bottles. The content is calculated with the following rule of thumb: A 20l bottle with 200bar contains 20 × 200 = 4000l helium. Since the quantity of a 20l helium bottle is usually just enough, we recommend buying two 20l bottles as a precaution. Then you are on the safe side. For an exact calculation we recommend our helium calculator.
Where can I buy a weather balloon
Fortunately, the search for the weather balloon has come to an end, because that’s why we set up an online shop! You will find everything concerning stratospheric flights there.
How can I locate my camera after landing?
There mus be a reliable GPS tracker on board must , with whose help you can locate the camera very easily and to an accuracy of 5m. Once the probe has landed again, the coordinates can be easily entered into Google Maps or a navigation device and the search can begin.
How far do weather balloons fly?
Another factor is the amount of helium: If you fill more helium in the weather balloon, the balloon rises faster and will burst more likely. This can shorten the distance between the starting point and the landing place. Our balloons usually cover a distance of 50-150 km as the crow flies.
What is the probability that the camera will land on a roof?
There is almost no need to be afraid of water if you do not start directly at the sea. You almost have to be “lucky” to land in a river or lake in Germany, as the water area in Germany is only 0.3%. A look at Google Earth shows how little land has actually been built on. Should the styrofoam probe land in the water, it’s no problem: Styrofoam floats.
How cold is it in the startosphere?
I’m a student and I need money for the project. Suggestions?
- 1. let anyone who donates something write a message or place a logo that you shoot into space. Point the camera at the logos during the mission and put a video of it on YouTube.
- 2. let anyone who donates something write a special design or message on a small piece of paper and stick it on a piece of balsa wood. Send it to the universe and give it back to your sponsors with a certificate “Been to the stratosphere!
- 3. Contact your local newspapers and offer a topic suggestion about your project. If they agree, you have a great opportunity to give your sponsors the publicity they want.
