A timeline has gone up for Saturday’s events in deep space. The ESA probe Rosetta will be mounting a flyby of the asteroid 21 Lutetia, while Herschel conducts a simultaneous campaign of infrared observations of the body. Results will be piped through a live webcast as well as to a media event on going at ESOC (“This is the asteroid getting bigger. Bigger. Bigger than we thought. And now the screen is blank and Herschel has recorded a significant increase in infrared emissions. Oh dear.”).
