Despite Snafus, ESA’s Euclid Should Start Routine Science in January
Even the most successful space missions initially encounter snafus which can keep their project managers up all night. And the European Space Agency's Euclid mission is no exception. Roughly one month after its launch this past July, the team realized that the spacecraft had issues. Ones that could jeopardize Euclid’s forthcoming wide-field survey to finally understand the cosmos’ unseen dark energy and dark matter. Although Euclid was not designed to study asteroids, it is expected observe more than 150,000 of them as foreground objects in its images. This will produce a gold mine of data on asteroids; we will characterize smaller and more distant asteroids than possible from ground-based telescopes, Humberto Campins, a planetary scientist at the University of Central Florida in Orlando, told me via email.
