Orbiter Pair Expands View of Martian Ionosphere
Radio signals sent between two Mars orbiters—rather than between an orbiter and an Earth-based receiver—capture new insights into atmospheric dynamics.
Nudging Earth’s Ionosphere Helps Us Learn More About It
New observations and simulations capture the physics at play across each of the three main ionospheric regions.
Mini Dunes Form When Sand Stops Bouncing
Decoding how sand grains move and accumulate on Earth can also help scientists understand dune formation on Mars.
Two Neutron-Monitoring Networks Are Better Than One
Hydrologists, atmospheric scientists, and space scientists are teaming up to keep a closer eye on soil moisture, hazardous space weather, and more.
Trump Withdraws Nomination for NASA Administrator
In a move that worried politicians and space scientists alike, President Trump announced on 31 May that he will withdraw his nomination of Jared Isaacman for the position of NASA administration.
The Late, Great Gaia Helps Reveal Asteroid Masses
Astronomers are using data from the recently decommissioned star-mapping satellite to help determine masses and more accurate orbits of celestial bodies closer to home.
Proposed Experiment Could Clarify Origin of Martian Methane
Curiosity’s detection of the gas, if atmospheric, could be an indicator of life on the Red Planet. But skeptics say further work is needed to rule out the rover itself as the source of the methane.
A Geologic Map of the Asteroid Belt
Scientists leveraged a global camera network and doorbell cameras to track dozens of meteorites to their asteroid families.
Young Rivers on a Martian Volcano Reveal Insights into the Amazonian Climate
A comprehensive inventory of rivers on Alba Mons on Mars reveals a prolonged history of erosion and development into mature drainage networks during the Amazonian, with contributions of rainfall and snow melt.
Distant Icy Twins Might Actually Be Triplets
The trans-Neptunian object Altjira, 44 times farther from the Sun than Earth is, could be the second known trinary, confirming a theory about the formation of our solar system.
