Bringing Mars down to Earth

By Adam Hadhazy

August 23, 2020

The United States and Europe are taking their first steps in a yearslong campaign to deliver rocks and soil from the red planet to terrestrial labs for unparalleled examination. Adam Hadhazy takes us step-by-step through the complex, yet in some ways conservative, mission.

Cosmic GPS

May 1, 2020

The U.S. Global Positioning System has changed how we operate spacecraft in low-Earth orbit. Now GPS is starting to do the equivalent for spacecraft flying beyond the GPS constellation, and someday possibly all the way to the moon, where positioning contributions from other nations could add up to stunning accuracy. Adam Hadhazy tells the story.

More than government work

January 1, 2020

Defending Earth from “city killer” asteroids will require a partnership between governments and the burgeoning commercial space industry. Retired NASA mission planner Don A. Nelson makes the case.

Decision time — NASA’s New Frontiers

By Adam Hadhazy

June 1, 2019

UPDATE: Dragonfly wins. See News story – NASA has limited dollars for exploring the solar system with robotic spacecraft, and it can take a decade to get such a probe to its destination. Careers are made or stalled when NASA selects a proposed mission, which is why the agency’s latest New Frontiers competition is such a high-stakes affair. Adam Hadhazy spoke to the finalists vying for the prize.

How China’s January landing on the far side of the moon is helping open this neglected other half to science and human utilization.

Digging in to Mars

By Amanda Miller

March 1, 2019

Every square meter of Mars has been photographed from orbit; its dirt has been scooped up and heated to reveal its constituent chemicals; rovers have driven for kilometers. The surface of Mars, though, has never been dug so deep. That is set to change. Cracking the surface of Mars could deliver readings that will upend tenets about planetary evolution.

Imaging a habitable world

January 2, 2019

Scientists are detecting exoplanets daily by the slight decrease in light from a host star as a planet transits in front of it. Photos of such a planet could tell us whether or not we are alone in the universe. Louis D. Friedman and Slava G. Turyshev think they have a solution for delivering this photographic evidence, one that will require a 900 trillion-kilometer journey and applying a phenomenon discovered by Einstein.

Better asteroid alerts

NASA plans to spend $3.8 million over the next four years adding two telescopes to its asteroid search network to do a more complete job of detecting small objects as they are closing in on Earth.

Quantum promises

September 27, 2018

Precise navigation will be a necessity for safe human exploration of Mars and other celestial bodies in deep space. A pair of experiments about to get underway could change the way this navigation is done, and for the better.

Taking on the sun

By Tom Risen

August 31, 2018

NASA’s Parker Solar Probe, now on its way toward the sun, must survive the searing temperatures in the solar corona to unlock the processes driving the solar wind and coronal mass ejections that can harm satellites and electronics on Earth. We spoke to the scientists and engineers behind Parker’s thermal protection strategy.

Destination: Mercury

By Adam Hadhazy

August 31, 2018

The BepiColombo mission to Mercury, getting underway in October, could answer vexing questions about the innermost planet’s core and its Earth-like magnetic field. And the answers could shed light on planetary matters far beyond our solar system.

Drone tech opens door to Mars Helicopter

By Tom Risen

June 6, 2018

NASA’s announcement that it will add a tiny helicopter to its planned Mars 2020 rover came after a series of test flights inside a vacuum chamber proved the feasibility of adapting consumer drone technologies into a craft capable of flying in an atmosphere just 1 percent as dense as Earth’s.
