Chapter 1: The Launch of ICON

NASA has been making headlines with ambitious plans for lunar missions and potential human expeditions to Mars. However, its latest endeavor is focused on studying a more immediate aspect of our atmosphere. The Ionospheric Connection Explorer (ICON) spacecraft has successfully entered orbit after enduring several delays. This probe operates at a lower altitude than many satellites, as it seeks to explore the ionosphere—a captivating yet challenging region of the atmosphere.

The ICON initiative was initiated in 2013, alongside the Global-scale Observations of the Limb and Disk (GOLD) mission. While GOLD was launched in early 2018, the journey for ICON has proven significantly more complicated than anticipated. This difficulty is not attributed to the spacecraft itself but rather to issues with its launch vehicle. The Pegasus XL rocket from Northrop Grumman, which has been in operation since the 1990s and is launched from an aircraft, encountered repeated system failures during NASA's launch attempts.

Fortunately, luck was on NASA's side late Thursday, enabling the successful launch of ICON into low-Earth orbit. The ionosphere, which encompasses both the exosphere and thermosphere, represents the uppermost layer of the atmosphere. It is termed the ionosphere due to its ionized characteristics. This region is vital for radio signal transmission, influences electrical activities in the lower atmosphere, and affects how Earth interacts with solar weather. Studying the ionosphere from the ground is challenging, and most satellites are positioned too high to adequately observe it. ICON addresses this gap by operating at an altitude of 360 miles (579 kilometers) with an orbital inclination of 27 degrees.

The spacecraft is equipped with a range of specialized instruments designed to analyze and monitor ionospheric phenomena. These include an ion drift meter to detect subtle plasma movements, a sensor for wind speed and temperature, and various infrared imaging tools. Through ICON, NASA aims to investigate the phenomenon known as airglow within the ionosphere. While full-fledged auroras can be observed near the poles, airglow represents a less intense version of this process that can occur in various locations. By studying airglow, NASA will be able to track particle movements throughout the upper atmosphere.

NASA anticipates receiving the first data from ICON in November. The primary mission is expected to span approximately two years, potentially enhancing our understanding of the ionosphere's impact on human activities both on Earth and in space.
