15/16 As you can see, 803.5 m/s delta-V is the maximum possible given this ideal situation. Dr Loeb never mentions this fact, and indeed graphs showing delta-V continue beyond this theoretical maximum.

11/16 Let's pause here for a second and talk about Specific Impulse (Isp). This is a measure of how efficient the engine is with the fuel that it burns.

Back to P. 4...

I actually agree with Dr. Loeb here. 340s Isp for this engine is *optimistic*. That's one way of putting it.

This tells us how much total thrust was available to Juno when it was launched, which isn't relevant to the question of reaching 3I/ATLAS.

Translating MAGA:
"Why are you hurting me? I definitely voted to hurt black people and cut government waste. Now you're telling me I was the waste all along, and that can't be right. I only wanted to hurt other people."

Translating MAGA:

"I was a DEI hire with both my disabled and veteran status, and I voted to fire all the DEI hires but I didn't realize you would fire me too! I just wanted you to fire all the black people! *Angry entitled noises*"

These people are disgusting. They deserve this.

Translating MAGA:
"I love that you're hurting other people I didn't like, but now I'm hearing you might be hurting people I like as well. Could you maybe not do that? Still luv u tho!"

Thanks to the Trump first term, and Mitch McConnell, who is feeling regret for his actions far too late, and the packed SCOTUS, Trump actually can't violate any law regardless of his motivations. He's immune.

He's actually speaking to his extremist followers here. He wants brownshirt vigilantes.

I hope everybody who voted for Trump gets exactly what they voted for. I hope they get it hard. BOHICA, idiots.

All you morons who voted for Trump because of inflation at 3% was such a problem for you, when Trump's only plan was tariffs that would make inflation worse.

Well, all I can say is you fucked around and now you're about to find out.

3% was bad? Try 12% or more on for size.

Idiots.

Centerists only accelerate the race to the right. Come out as opposing the extreme right's agenda *and cast a meaningful vote against it,* or become a fascist collaborator. Those are your choices.
