| Inspired by the work of the UTARC team and their near trans-atlantic crossing with SNOX IV the aim of Atlas is to be a co-operative attempt to break the Amateur Highest GPS Reported Maximum Altitude with a balloon which at present stands at 120,522ft (36744m). | Inspired by the work of the UTARC team and their near trans-atlantic crossing with SNOX IV the aim of Atlas is to be a co-operative attempt to break the Amateur Highest GPS Reported Maximum Altitude with a balloon which at present stands at 120,522ft (36744m). | ||
| - | While in the early planning stages the present plan is to put together an exceedingly light payload and use a dual balloon system to lift the payload to up to an altitude of 130,000ft. Launching from EARs it will be necessary to carefully monitor the weather to chose a day when there is little to no wind (similar to the FHALP-2 launch) which will allow a slow ascent rate without the risk of landing in the sea. | + | While in the early planning stages the present plan is to put together an exceedingly light payload and use a dual balloon system to lift the payload to up to an altitude of 130,000ft.
