Hope at Mars, Mapping the Cosmos, and Dark Energy
In the February issue of Sky & Telescope, we go behind the scenes of the United Arab Emirates Hope Mission to Mars. The Hope spacecraft is obtaining a comprehensive view of the Martian atmosphere and answering questions about the Red Planet’s climate and weather. And while we’re still talking big picture, the Dark Energy Spectroscopic Instrument (DESI) survey has set out to map the entire universe in 3D and shine a light on the history of the cosmos. Scientists intend to use this map to unravel the secrets of dark energy. To offer our readers some context, we also go into the history of the mysterious repulsive force and how it was discovered. While DESI captures 100,000 spectra per night to create its massive map, we show readers how to use their existing setups to capture targets that don’t fit in their current telescope’s field of view.
