For Earth Day 2021, we explore the connections of Earth systems and NASA's ability to observe them in a changing world, highlighting the links between dust transport, vegetation, water quality, conservation and human health, the cryosphere, and disasters.

NASA's Parker Solar Probe and its United Launch Alliance Delta IV Heavy launch vehicle prepare for an unprecedented mission to "kiss the Sun." NASA launch schedule: https://go.nasa.gov/2JfklMB About the mission: https://go.nasa.gov/2ubAwFS The spacecraft aims to unravel 60 years' worth of mysteries surrounding the Sun’s corona. Watch this 4K video as NASA’s Launch Services Program continues the countdown to T-zero. Visit https://go.nasa.gov/SolarProbe to learn more and watch the historic launch on NASA TV in the coming weeks.

As of June 2020, NASA’s Solar Dynamics Observatory — SDO — has now been watching the Sun non-stop for over a full decade. From its orbit in space around the Earth, SDO has gathered 425 million high-resolution images of the Sun, amassing 20 million gigabytes of data over the past 10 years. This information has enabled countless new discoveries about the workings of our closest star and how it influences the solar system. With a triad of instruments, SDO captures an image of the Sun every 0.75 seconds. The Atmospheric Imaging Assembly (AIA) instrument alone captures images every 12 seconds at 10 different wavelengths of light. This 10-year time lapse showcases photos taken at a wavelength of 17.1 nanometers, which is an extreme ultraviolet wavelength that shows the Sun’s outermost atmospheric layer — the corona. Compiling one photo every hour, the movie condenses a decade of the Sun into 61 minutes. The video shows the rise and fall in activity that occurs as part of the Sun’s 11-year solar cycle and notable events, like transiting planets and eruptions. The custom music, titled “Solar Observer,” was composed by musician Lars Leonhard (https://www.lars-leonhard.de/). While SDO has kept an unblinking eye pointed towards the Sun, there have been a few moments it missed. The dark frames in the video are caused by Earth or the Moon eclipsing SDO as they pass between the spacecraft and the Sun. A longer blackout in 2016 was caused by a temporary issue with the AIA instrument that was successfully resolved after a week. The images where the Sun is off-center were observed when SDO was calibrating its instruments. SDO and other NASA missions will continue to watch our Sun in the years to come, providing further insights about our place in space and information to keep our astronauts and assets safe.

NASA’s Lucy mission tests the deployment of its solar arrays in the thermal vacuum chamber at Lockheed Martin Space in Littleton, Colorado. Each of the two circular arrays is nearly 24 feet (7.3 m) wide. These arrays will power Lucy on its 12-year odyssey through the Jupiter Trojan asteroids, breaking records for a solar powered mission by traveling 530 million miles (853 million km) from the Sun. These large arrays will capture the sunlight needed to power the spacecraft as it travels through deep space. More: nasa.gov/lucy Music: "CSI," Anthony Edward Phillips, Atmosphere Music, Ltd.
