Ulysses Spacecraft Not Dead Yet
iminplaya sends in the good news that reports of the death of the Ulysses mission are premature. (We've discussed the impending shutdown of the 17-year-old mission a couple of times this year.) Ulysses is a joint NASA / ESA mission to study the sun from an orbit inclined almost 90 degrees from the ecliptic. From the Planetary Society blog post: "Ulysses is not dead yet. ESA issued a statement in February saying that, as Ulysses' radioisotope thermoelectric generators were running out of power, the spacecraft would likely die some time this year. The actual death blow to the spacecraft was likely to be the freezing of hydrazine fuel in a cold spot in a fuel line. Mission controllers found creative ways to prevent the freezing, but the solution was not a long-term one, and ESA had a ceremonial send-off and wrap-up of the mission in mid-June, announcing that the spacecraft would be shut down on July 1. However, it now appears that announcement was premature. ESA issued a statement on July 3 titled 'Ulysses hanging on valiantly.' And on Wednesday, the [Ulysses mission operations manager indicated] that Ulysses' voyage could actually continue for some time."
You don't need billion dollar budget programs to achieve amazing science, low cost well thought out missions can do great things. maybe it's the thinking part that has them stumped.
If you mod me down, I will become more powerful than you can imagine....
An appropriate poem for a dieing spacecraft.
Come, my friends,
'T is not too late to seek a newer world.
Push off, and sitting well in order smite
The sounding furrows; for my purpose holds
To sail beyond the sunset, and the baths
Of all the western stars, until I die.
It may be that the gulfs will wash us down:
It may be we shall touch the Happy Isles,
And see the great Achilles, whom we knew.
Tho' much is taken, much abides; and tho'
We are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.
Well, to be fair, Odysseus was a general of sorts too. :-)
The blog article at the Planetary Society website says that Ulysses will encounter Jupiter and be ejected from the solar system. Is this a theoretical possibility, or has a date for this been determined? Ulysses originally encountered Jupiter to fling it out of the ecliptic plane so it could study the sun at high latitudes. Its aphelion is still at Jupiter's orbit. If it encounters Jupiter again, any number of things could happen to it. The statement about it being ejected seems to imply that a specific encounter trajectory is already predicted.
Written over 700 years ago and still brilliant. This is just a small extract:
"O frati", dissi "che per cento milia
perigli siete giunti a l'occidente,
a questa tanto picciola vigilia
d'i nostri sensi ch'è del rimanente,
non vogliate negar l'esperienza,
di retro al sol, del mondo sanza gente.
Considerate la vostra semenza:
fatti non foste a viver come bruti,
ma per seguir virtute e canoscenza''.
Li miei compagni fec'io sì aguti,
con questa orazion picciola, al cammino,
che a pena poscia li avrei ritenuti;
e volta nostra poppa nel mattino,
de' remi facemmo ali al folle volo,
sempre acquistando dal lato mancino.
Tutte le stelle già de l'altro polo
vedea la notte e 'l nostro tanto basso,
che non surgea fuor del marin suolo.
From scarped cliff or quarried stone she cries "A thousand types are gone, I care for nothing, no not one."
