We’re about to fly a spacecraft into the Sun for the first time

Come to Quark’s, Quark’s is Fun!
General off-topic chat for the crew of startrek.website. Trek-adjacent discussions, other sci-fi television, navigating the Fediverse, server meta (within reason), selling expired cases of Yamok sauce, it’s all fair game.
Delta = change and v = velocity
So delta v is change in velocity
Also known as acceleration. It's just the "spacey* term for it.
Now in space there's generally nothing slowing you down except gravity... So to add delta v you simply run your engine or burn your rocket. But that uses fuel which is why it's hard to "add enough delta v to overcome our orbital velocity"... You need a whole lot of fuel compared to the mass you're trying to move.
Thank you. That was a perfect explanation.
