Europe’s Rosetta spacecraft closed out a historic 4.9-billion-mile journey Friday with a slow-speed crash into the nucleus of comet 67P/Churyumov-Gerasimenko, the tiny world it has studied for the last two years, capturing some of the mission’s best science data to help unravel the inner workings of the comet. Confirmation of the crash landing arrived on Earth at 1119 GMT (7:19 a.m. EDT).

The European Space Agency has reserved an Ariane launcher to send a spacecraft toward Jupiter in May 2022, and the mission’s project manager said Tuesday officials could assign the probe to Europe’s new Ariane 6 rocket, assuming the vehicle has a successful debut by the end of 2020.

The ExoMars Trace Gas Orbiter, a Russian-launched, European-built spacecraft that arrived at Mars in October, is starting to dip into the upper reaches of the red planet’s atmosphere in a year-long “aerobraking” campaign place the observatory in the right position to hunt for methane, an indicator of potential biological activity.
