Global-scale External Magnetic Fields at Mars Measured at Satellite Altitude

Editor’s Highlight—   This article identifies previously undescribed patterns in the Martian external field, finds a previously undescribed source of external fields on Mars, and describes a way of using the time-dependence of external fields to calculate bulk conductivity from InSight magnetic measurements..... more

Lab Tests Probe Carbon Planets’ Inner Dynamics

Terri Cook, Freelance Writer

From Research Spotlights— Thermal convection in deep interiors could be more vigorous in carbide planets than in comparably sized silicate planets, according to new, high-pressure measurements of silicon carbide.  Recent astronomical observations indicate that certain stars with high carbon-to-oxygen.... more

Meteorites Mix Moon’s Surface at Both Small and Large Scales

Terri Cook, Freelance Writer

From Research Spotlights— A three-dimensional model of material transport suggests that impact cratering can mix lunar soils across distances of more than 100 kilometers.  Unlike Earth, where familiar forces like wind and rain are constantly mixing the planet’s soil, the Moon has almost no.... more

Researchers propose new type of planetary object

Press Release— Scientists suggest in a new study the existence of a planetary object called a “synestia,” a huge, spinning, donut-shaped mass of hot, vaporized rock, formed as planet-sized objects smash into each other. At one point early in its history, Earth was likely a synestia, said Sarah Stewart,.... more

Ancient Impact May Have Triggered Long-Term Volcanic Eruptions

Sarah Stanley, Freelance Writer

Scientists revisit Canada’s Sudbury crater in light of new evidence from other planets that suggests an alternative postimpact history.  Approximately 1.85 billion years ago, a comet up to 15 kilometers wide smashed into shallow seawater in what is now the city of Sudbury, Ontario. On impact, the comet.... more

The western Qaidam Basin as a Martian environmental analogue: An overview

Editor’s Highlight­­— There are many similarities between the Qaidam Basin on the Tibetan Plateau and contemporary Mars. As such it can be used as an “environmental analogue”; these are locations that are useful in the study of other planets in order to interpret data received from rovers and landers.... more
