The first link leads to an older article that does explain it. What they mean is that the planets’ orbits are in resonance, which means that their orbital periods are related by integer ratios. (For example one planet completing exactly three orbits in the time it takes another to complete two)
Okay, that’s really cool and 25 megabits per second is actually very good compared to what they get back from other probes. At speeds like that, they could send back 4k pictures, which would be extremely high resolution for craft like this.
In an update posted on Sunday (Feb. 18), ESA said that the rentry ERS-2 is expected to take place on Wednesday (Feb. 21) at 10:19 a.m. ET (1519 GMT), plus or minus around 19 hours. This uncertainty is due to the “influence of unpredictable solar activity, which affects the density of Earth’s atmosphere” and can therefore change how much drag pulls on the satellite on its way down, ESA wrote.
Plus or minus 19hrs due to the sun’s effect on the density of the atmosphere. Mind blown.
‘Speed of light’ compared to what? is what you need to worry about. Most things in the universe won’t be moving at the speed of light compared to you (or whatever you’re inside of), and when you run into them, you won’t last for long.
If you’re zooming past the Earth at the speed of light headed straight at the Moon, you’ve got about 1 second to enjoy that before you make a very, VERY large crater.
If you change course and head straight at a frozen tardigrade, it will make a VERY large crater in you.
To actually reach the speed of light you'd be massless, so the only damage, would be from momentum transfer, at which point your particles would be reflected or absorbed like light.
But that aside, mostly I was referring to your statement:
'Speed of Light' compared to what?
Which is really not a concern. It's the speed of light for everyone with respect to everything, or it isn't the speed of light. Like, two beams of light going in opposite directions don't see the other light beam going at 2x the speed of light, just at the speed of light with lots of time dialation.
You already knew the answer to ‘What would happen if you moved at the speed of light’ was was “To actually reach the speed of light you’d be massless.” No shit. The question was already massless.
They say he can explore small caves, but wouldn’t this little guy be solar charged and they could lose him if he doesn’t have enough juice to get back to the surface?
