Even as Tom Economou approached retirement age in 1994, he began planning an instrument for the European Space Agency's Rosetta mission to a comet. He still remembers the reaction of Riccardo Levi-Setti, then director of ...
(Phys.org) —An image snapped earlier this month by ESA's Rosetta spacecraft shows its target comet has quietened, demonstrating the unpredictable nature of these enigmatic objects.
It took a set of retro-looking images to reawaken the world's sense of wonder about space exploration.
Generally speaking, space missions fall into one of three categories: difficult, more difficult, and ridiculously difficult.
Europe's comet probe Philae was "working well" despite a rough-and-tumble touchdown that left it partly shadowed from battery-boosting sunlight, ground controllers said Thursday.
Imagine launching a robotic spacecraft on a ten-year mission to land on a comet, 600 million kilometres from Earth, knowing that you will not be able to make any physical repairs to the craft during the journey. This daunting ...
The European Space Agency is making final preparations to land the first unmanned spacecraft on a comet next week, and scientists are hoping that technology designed a quarter century ago will perform as planned.
When Rosetta was launched more than a decade ago, it was a dry-as-dust science story—an unmanned spacecraft and its research payload were being launched to investigate a comet.
A University of Leicester planetary scientist has hailed the European Space Agency's mission to land a probe on a fast-moving comet as a success despite issues with the landing.
A first evaluation of the data that comet lander Philae sent to the European Space Center before its depleted batteries forced it to go silent will be released Monday, the German aeronautics and space research center said
