Nasa will deploy a high-tech telescope aboard on the stratospheric balloon in the Stratosphere layer of the earth’s atmosphere to study the cosmos. The telescope will be 8.4-foot (2.5-meter) and launch in December 2023.
Telescope named ASTHROS (short for Astrophysics Stratospheric Telescope for High Spectral Resolution Observations at Submillimeter-wavelengths) and will spend about three weeks the Stratosphere.
ASTHROS will measure the motion and speed of gas for newly formed stars by observing infrared light. NASA believes the mission will further help on how galaxies formed and evolved over time. During the mission, ASTHROS will focus on four targets. Among four stars, two are lying in our Milky Way galaxy. A third target will be the galaxy Messier 83. In addition, it will also study TW Hydrae, a young star surrounded by dust and gas.
The telescope will be on-boarded on a stadium-sized balloon that will be inflated with Helium. It will be placed at an altitude of about 130,000 feet (40 kilometers) from the earth’s surface. The telescope will be equipped with mirrors, lenses, and detectors to capture far-infrared light.
Since far-infrared telescope needs to keep cold during the mission. ASTHORS will use cryocooler which will use electricity to the observing telescope and balloon at close to -minus 451.3-degrees Fahrenheit.
Once the mission will complete, scientists will bring back the balloon and telescope to the ground so that it can be recovered and refurbished to fly again.
