Quantum sensor can detect electromagnetic signals of any frequency

Quantum sensor can detect electromagnetic signals of any frequency

MIT researchers have developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness.

Researcher shows how elliptical craters could shed light on age of Saturn’s moons

Researcher shows how elliptical craters could shed light on age of Saturn’s moons

A unique pattern of elliptical craters along the equators of Saturnian satellites Tethys and Dione indicates slow and shallow impacts on an east/west trajectory and the possibility of planetocentric impactor populations similar to others in the outer solar system. Credit: NASA/JPL/SSI/Lunar and Planetary Institute A new SwRI study describes how unique populations of craters on … Read more

The NASA/ESA Hubble Space Telescope captured this glittering scene using its Wide Field Camera 3 and Advanced Camera for Surveys. Globular clusters are stable, tightly bound groups of tens … Read more

Martian moon could be crucial for asteroid mining

Martian moon could be crucial for asteroid mining

However, profitable mining entails balancing more than just the cost of traveling across a distance, and any asteroid mining operation must take into account the expense of the rendezvous—slowing the spacecraft down once it arrives—as well as the cost of shipping the ore back to a processing facility. The cost (and weight) of the fuel … Read more

China says it will bring Mars samples back to Earth 2 years before NASA

China says it will bring Mars samples back to Earth 2 years before NASA

China’s space agency aims to complete its Mars sample return mission by 2031, two years before NASA and the European Space Agency (ESA) complete their joint mission. Tianwen-1 Mars orbiter and rover mission chief designer Sun Zezhou outlined a new mission profile for China’s Mars sample return during a June 20 presentation, as per a … Read more
