The Year 2020 in Pictures

It was a tough year on planet Earth. The COVID-19 pandemic ravaged the globe while protesters around the world rallied to end systemic racism. Space exploration is an inherently optimistic endeavor. Amidst the year’s turmoil, we saw some truly awe-inspiring cosmic moments. In May, astronauts Bob Behnken and Doug Hurley flew a SpaceX Crew Dragon to the International Space Station and back, completing the first-ever commercial, crewed, orbital spaceflight. The mission rejuvenated our appreciation for the beauty and drama of human spaceflight.

We were also inspired by the launch of 3 new Mars missions. Although the pandemic significantly slowed most space activities, technicians in multiple countries managed to meet a brief launch window that only comes around every 2 years when Mars and Earth are optimally aligned. The name of 2 missions, Perseverance and Hope, took on a whole new significance.

High above Earth, The Planetary Society’s LightSail 2 spacecraft continued to demonstrate solar sailing technologies while capturing beautiful pictures of our planet. Elsewhere in the solar system, NASA’s OSIRIS-REx successfully collected a sample from asteroid Bennu while Hayabusa2 flew back to Earth carrying dust and rock from asteroid Ryugu. In September, scientists using Earth-based telescopes announced that they had found phosphine on Venus, raising the prospect for life existing there. With these accomplishments came the reminder that we humans can do incredible things when we work together, and there is hope for better days ahead.

Mars or Earth?

Comet NEOWISE by Adam Block
Comet NEOWISE by Adam Block In mid-2020, many stargazers around the world were able to see comet NEOWISE with the naked eye. This image of the comet was captured from Gila Bend, Arizona on 18 July 2020 by astrophotographer Adam Block.Image: Adam Block
Three telescopic views of Venus
Three telescopic views of Venus These 3 views of Venus were captured by the Chilescope Observatory in Chile on 15 February 2020. Visible-light views of Venus show a nearly featureless surface, so scientists use filters such as infrared (left, center) and ultraviolet (right) to capture atmospheric details unseen by the human eye.Image: S.

LightSail 2 image of Arabian Peninsula
LightSail 2 image of Arabian Peninsula This image, taken by The Planetary Society’s LightSail 2 spacecraft on 19 May 2020, shows the Arabian Peninsula with the Red Sea and Nile River at left and the Persian Gulf at right. North is approximately at top right. A material similar to a piece of fishing line, called Spectraline, held the spacecraft's solar panels closed prior to sail deployment and can be seen at upper left. This image has been color-adjusted, and some distortion from the camera’s 180-degree fisheye lens has been removed.Image: The Planetary Society
Icy Mars Cliffs
Icy Mars Cliffs About one-third of Mars has ice just beneath the surface. Scientists study the ice to learn what early Mars was like and whether it was warm and wet long enough for life to take hold. In this false-color image from NASA’s Mars Reconnaissance Orbiter, layers of bluish ice can be seen layered inside an exposed brownish cliff face. MRO takes repeat images of scenes like this, occasionally revealing ice boulders that have tumbled down slopes.Image: NASA / JPL-Caltech / University of Arizona

OSIRIS-REx Sample Collection Location
OSIRIS-REx Sample Collection Location This mosaic of the primary sample collection site for NASA’s OSIRIS- REx mission was created with 345 images captured by the spacecraft on 3 March 2020. OSIRIS-REx was 250 meters above the surface at the time. The specific collection site is the relatively rock-free area in the middle. The boulder in the upper right is 13 meters wide on its longest axis.Image: NASA/Goddard/University of Arizona
