Why Nasa Is Launching a 

Telescope On A Hot Air Balloon

Most Telescopes Fall Into

Two categories: ground-based telescopes, or space-based telescopes, which can orbit around the Earth or the Sun


There is a third option for research telescopes that are neither on the ground nor in space


It is those that operate at high altitudes far above the altitude at which planes fly.

How Do You Get a Telescope

To such an altitude? By attaching it to an enormous balloon. NASA has plans to use a huge balloon

The Size of a Football

Field when fully inflated to carry a telescope to an altitude of 130,000 feet over Antarctica.

The ASTHROS Project, Which Stands

For Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths

Includes a Telescope

With an 8.2-foot mirror that had to be made extremely thin so it is light enough to be lifted by the balloon.

The Aim of the Project

Is to study a phenomenon called stellar feedback, which is a process regulating the rate of new star formation.
