The European Space Agency successfully landed a probe on a comet on Wednesday. The probe known as Filey is transmitting signals and has begun sending back photos. Bart scientists are unsure whether they can start experiments as the landing didn't go entirely to plan. The craft is extremely unstable after harpoons that should have fired into the comet's surface to anchor it didn't fire. It is concerned that the craft could float away in the low gravity. This was the moment history was made. After a ten-year journey through space, Filey connected with a comet. The hope his scientists will still be able to drill for samples to gain clues about our solar system.
