Stars Project

Adeptium's going into space! The STARS Project is a series of educational near-space remote sensing missions, using High Altitude Balloons to take an instrument package to over 100,000ft (30km) - where the atmosphere's a hundredth of its sea-level pressure, and temperatures are -40 degrees...the only figure that's the same in Centigrade and Fahrenheit.

Look out for our Quakes Alert service, launching soon. When a big quake happens anywhere in the world, we'll send you an email within two minutes of USGS publishing the data, including updates on magnitudes - plus a daily summary of all significant quakes reported around the world. It'll be free forever, for the founder members. If you'd like to be considered as a beta tester, email us at This e-mail address is being protected from spambots. You need JavaScript enabled to view it , and we'll let you know when the beta programme opens.
