Serious comment to anyone on the JSTUC or who works on APT: can we *please* get a version that updates in place? Every other piece of software I work with can do this.

Of course a cursory review of Juno's technical specs show the engine has a less-efficient specific impulse of 318s, and it has already expended at least 1/5 of its fuel for Jupiter orbit-insertion (to say nothing of maneuvers since then).

According to these calculations, Juno could just do a flyby 3I/ATLAS assuming the spacecraft's engine has a specific impulse of 340s and uses its entire fuel load.

I will say this highlights the wisdom of how NASA was created 60 years ago: by placing the centers all over the country, we end up with a lot of members of Congress across party lines (like the Alabama delegation) who don't want things cut.

Even if day to day it feels inefficient.

The bill passed last night had funding levels through 2034, and (on my quick skim) they looked roughly constant in current dollars.

But you're right that even if the 250 funding makes it through mostly intact this year, we all get to keep doing this.

So cautious optimism about overall levels, and it seems like the scenario of a 50% budget cut to NSF and no new awards this year may be prevented.

For, borne on the night-wind of the Past,
Through all our history, to the last,
In the hour of darkness and peril and need,
The people will waken and listen to hear
The hurrying hoof-beats of that steed,
And the midnight message of Paul Revere.
