BepiColombo flew by the Earth once, Venus twice, and Mercury itself six times to use those planets' gravity as a way of putting on the brakes.
Once the European and Japanese Space Agency's spacecraft arrives, it will study how Mercury formed and why there is ice at the poles.
Dunkleosteus Torelli lived about 360 million years ago.
The front part of its body and head were covered in bony armor.
Instead of teeth, it had what are called bone blades, razor-sharp bone blades.
The new research, reported by scientists at Case Western Reserve University, is based on fossils unearthed in the 1960s when Interstate 71 through Cleveland was being built.
Researchers now have a clearer picture of how Dunkelosteus used its muscular jawbones to pulverize prey.
Additional information may be coming.
The new Cleveland Browns football stadium is being built in a location that should provide even more fossilized remnants of the extinct aquatic predator.
It's taken a while to get the escapade probes started on their journey.
They were supposed to be carried into space a year ago by the new Glenn rocket made by Blue Origin.
But a variety of factors led NASA to scrub those plans.
For a while, it wasn't clear how or whether Escapade would get to Mars, but ultimately NASA decided to put the probes back on the New Glenn rocket.
Once at Mars, ESCAPADE will make measurements that will help scientists understand how charged particles from the sun affect the thin Martian atmosphere.
The twin probes will let scientists create 3D images of how those particles are deflected around Mars by the planet's magnetic field.
