Here’s the challenge: Land a spacecraft that was designed to be an orbiter on the surface of a speeding comet that is millions of miles away and carry out pioneering science on the way down. It’s ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

After two years orbiting Comet 67P/Churyumov-Gerasimenko, the European Space Agency’s Rosetta orbiter met its end Friday morning. But the spacecraft did useful science to the last, delivering data ...

The ExoMars Trace Gas Orbiter has imaged the martian moon Phobos as part of a second set of test science measurements made since it arrived at the Red Planet on 19 October. The Trace Gas Orbiter (TGO) ...

Europe’s ExoMars orbiter has beamed back its first set of images of the Red Planet, showing high res close-ups of the surface and proving it will be sensitive enough to map gases in the atmosphere.

The missing Mars lander Schiaparelli, meant to touch down on the red planet last week, has been spotted, confirming that its landing did not go as planned. Two days after the craft went silent during ...

NASA has selected five U.S. aerospace companies to conduct concept studies for a potential future Mars orbiter mission. Such a mission would continue key capabilities including telecommunications and ...

Each of NASA’s two Martian rovers reported back to Earth last week via the new European orbiter, in the first successful relay test of Mars’ growing telecoms network. The Trace Gas Orbiter (TGO) put ...

This image from NASA’s Mars Reconnaissance Orbiter shows the landing zone for the European Space Agency’s Schiaparelli probe on Mars. Analysts say the bright spot shows where the lander’s parachute ...

After seven months of space travel, the European Schiaparelli spacecraft is only a couple days away from making its final descent to the surface of the Red Planet — and the stakes are high. The ...
