NASA Confirms Thousands of Massive, Ancient Volcanic Eruptions on Mars

Some volcanoes can produce eruptions so powerful they release oceans of dust and toxic gases into the air, blocking out sunlight and changing a planet’s climate for decades. By studying the topography and mineral composition of a portion of the Arabia Terra region in northern Mars, scientists recently found evidence for thousands of such eruptions, or “super eruptions,” which are the most violent volcanic explosions known.

Mars mission to pause for about 50 days

The Chinese probe Tianwen-1 will remain deactivated for about 50 days from mid-September due to the effect of solar electromagnetic radiation, local media reported today.

During this period, the Earth and Mars will be at the maximum distance and aligned with the Sun in between, so the solar electromagnetic radiation “will affect communications,” Zhang Rongqiao, Tianwen’s chief designer, told the media yesterday.

Such radiation will make communications difficult between the components of the mission, made up of an orbiter, a landing module and a rover called Zhurong, and control from Earth.

NASA’s Perseverance Rover Successfully Cores Its First Rock

Data received late Sept. 1 from NASA’s Perseverance rover indicate the team has achieved its goal of successfully coring a Mars rock. The initial images downlinked after the historic event show an intact sample present in the tube after coring. However, additional images taken after the arm completed sample acquisition were inconclusive due to poor sunlight conditions. Another round of images with better lighting will be taken before the sample processing continues.
