Floating in orbit above Mars, NASA’s 2001 Mars Odyssey orbiter captured a panorama of the Pink Planet’s largest volcanoes, Arsia Mons, peeking over a sea of clouds. The picturesque second presents an exceptionally uncommon view of a Martian volcano, displaying the landform at an angle in area that captures the planet’s horizon.
“We picked Arsia Mons hoping we might see the summit poke above the early morning clouds. And it didn’t disappoint,” Jonathon Hill, the operations lead for Odyssey’s digital camera and a mission planner at Arizona State College’s Mars House Flight Facility, known as the Thermal Emission Imaging System, or THEMIS, stated in a statement. THEMIS can view Mars in each seen and infrared gentle.
Launched in 2001, Odyssey has been circling round Mars for over 20 years, learning the Martian floor. However in 2023, the orbiter started taking breathtaking panoramic views of the Martian horizon. As a result of THEMIS can’t pivot to get these beautiful views, the orbiter flips on its facet, rotating a full 90 levels. That manner, it captured Mars’ “limb,” the sting of the planet’s horizon. That is THEMIS’ fourth limb observation since 2023.
Odyssey captured the picture on Could 2, simply earlier than daybreak. In it, Arsia Mons stands 12 miles (20 kilometers) excessive and measures 70 miles (450 km) in diameter. For comparability, Earth’s tallest volcano, Mauna Loa, stands 6 miles (9 km) above the seafloor and measures 75 miles (121 km) in diameter.
Arsia Mons can also be one in all Mars’ cloudiest volcanoes and the southernmost of the three Tharsis volcanoes that type Tharsis Montes, or Tharsis Mountains. These mountains are sometimes surrounded by water ice clouds, notably early within the morning. The clouds type when air expands because it blows up the edges of the mountain after which quickly cools.
This view additionally permits scientists to review Martian climate and phenomena like mud clouds and the way they alter over the course of the seasons. Odyssey may be capable of seize a couple of extra of those panoramas earlier than its eventual retirement, seemingly on the end of this year.
