Does Astropod actually go to space?

Yes!

The region of Space closest to Earth is called Near Space and it starts at around 19,000 metres. This is the altitude where the atmospheric pressure drops so low that water boils at human body temperature, and a human being cannot survive without a pressurised suit. This pressure is known as the Armstrong Limit and marks the boundary to Near Space. The exact altitude varies due to atmospheric conditions.

How high will Astropod go?

About 25,000 metres.

The ultimate altitude is dependent on a number of unpredictable environmental conditions. However, we’ve balanced the weight of the equipment, the size of the balloon and the amount of gas used to provide as consistent a result as possible and extensively tested the kits to ensure they perform to our expectations.

How long is the flight?

About 2.5 hours from release to landing.

The balloon will rise at a steady rate of 5.5 metres per second for about 90 minutes. Once it bursts, it will fall over a third of the way back down in less than 10 minutes! At this point, the air resistance will slowly increase. By the time it lands, about 1 hour after bursting, it will be moving at 5 metres per second.

Where will it land? How far will I have to travel to recover my Astropod?

The path your Astropod will take is determined by stratospheric wind patterns. On any given day, the flight path can be calculated to within 97% accuracy, but it can change quite a bit from day to day. However, it is very rare to see an Astropod flight travelling more than 100 miles. This is why we recommend setting aside a window of dates rather than aiming for a single day - you can choose the day with the best launching conditions.

Where can I launch my Astropod from?

We have 10 pre-approved launch sites across the UK where we hope to secure a permanent permission to launch, so all you'll have to do is enter a few details into a form on our site and wait for a response. Sign up to our mailing list to find out more as we continue to progress the conversation with the Civil Aviation Authority!

Do I need permission to launch my Astropod?

Yes. But don’t worry, we’ve made it as easy as possible.

The Civil Aviation Authority regulate access to airspace in the United Kingdom. Any aircraft, including the Astropod, must be operated with their permission, to avoid different air users causing each other problems.

We've arranged ten sites across the UK which the Civil Aviation Authority have pre-approved for launch. When you request delivery of your gas, you'll let us know which site you intend to use and when you plan to launch. We'll sort out all the rest so you don't have to.

Can anyone do this?

We've designed these kits to be as simple as possible to use. If you can operate a smartphone and have access to a computer, you will be able to use Astropod.

That said, Astropod is a hobbyist kit, not a toy. The balloon will be filled with helium gas, which is an asphyxiant and is supplied in pressurised cylinders. This kit is intended for use by adults. Children over the age of 8 may participate in the launch process but must be supervised at all times.

Do I need to buy anything else?

Yes, the gas must be purchased seperately.

Packaging the gas with the kit would have dramatically increased the price throughout the supply chain and would have presented many safety challenges.

Every Astropod kit includes a voucher offering 20% off your first gas purchase - we make almost no profit on selling gas.

Is Astropod safe?

Yes.

As long as the Astropod is used according to our instructions, this kit is completely safe to you, other people on the ground and other aircraft in the sky.

The Astropod with all components is light enough that it will do no damage on landing even if the parachute does not slow the descent. The components are all non-toxic (but we wouldn't recommend you eat the foam anyway) and when operated with a Notice To Airmen issued by the Civil Aviation Authority, it will pose no threat to other air users.

The helium gas provided with Astropod is an axphyxiant. Inhaling helium can deprive your brain of oxygen, causing light-headedness, unconsciousness, permanent brain damage and even death. It should be kept out of reach of children under 8 and launch team members under 18 should be supervised at all times by a responsible adult.

Is Astropod reusable?

Mostly!

At the peak of the flight, the balloon will burst and the gas will escape. Aside from the balloon and the gas however, every component can be reused. In the near future we will be selling a 'relaunch' bundle including a replacement balloon and more gas.

Can I use my own camera? Can I add a personal item to Astropod?

No.

To make the Astropod as simple to use as possible, we have designed the pod and the flight computer to fit perfectly together. In addition, the weight of the kit has been calculated to a very high degree of accuracy so that the payload will rise at the correct rate.

Adding additional weight to your Astropod will affect the rate at which the payload rises, which will undermine the accuracy of the flight path predictions and may cause your payload to travel substantially further.

Can I use Astropod if it's raining/snowing/windy?

Yes, but we recommend you launch on sunny day with little or no wind.

Bad weather will not stop the Astropod from flying. However, in wet conditions, there is a chance that moisture will accumulate on the lens, affecting the visual result of the flight. Also, filling the balloon will be significantly harder in any more than a gentle breeze.

Can I use Astropod outside the UK?

Not without a bit of work!

Every country has different airspace regulations and restrictions. We cannot advise on whether countries outside the UK will give permission for you to launch. Also, the flight computer uses a SIM card for location services. This SIM is tied to UK phone networks and a local alternative would be needed in another country.

If I lose my Astropod, can I get a refund?

No.

When correctly used, Astropod is recoverable. We have tested all the components many times and maintain a 100% recovery rate. We have confidence in the equipment and in the flight computer software, however Near Space ballooning is an inherently risky business. We cannot be considered responsible if you lose your payload, even if you follow all the instructions to the best of your ability.
