INFUSE MISSION (Syllabus: GS Paper 3 – Sci and Tech)

Context: Recently, the National Aeronautics and Space Administration (NASA) launched a sounding rocket as part of its INFUSE mission.

INFUSE Mission

• About: The Integral Field Ultraviolet Spectroscope Experiment (INFUSE) was launched from the White Sands Missile Range in New Mexico.
• It was launched with the aim of studying the Cygnus Loop, a supernova remnant.

What will the INFUSE mission do?

• The INFUSE mission is expected to collect information about the remnant for a few minutes from a height of 150 miles (240 km).
• Specifically, the instrument will gather light in far-ultraviolet wavelengths emanating from the Cygnus Loop.
• It will observe how the supernova releases energy into the Milky Way, capturing light emitted as the blast wave interacts with pockets of cold gas scattered throughout the galaxy.
• The mission's goal is to study the Cygnus Loop and gain insights into the life cycle of stars.

Cygnus Loop

• The Cygnus Loop is the remains of a star that was once 20 times the size of our Sun.
• Approximately 20,000 years ago, this star underwent a collapse due to its own gravity and exploded into a supernova.
• Even from a distance of 2,600 light-years away, astronomers estimate that the resulting burst of light would have been bright enough to be visible from Earth during the daytime.
