The mission's main science goal is to study stellar feedback, the process by which living stars disperse and reshape clouds of gas and dust that may eventually form new stars. Feedback regulates star formation in many galaxies, and too much can halt star formation entirely. ASTHROS will look at several star-forming regions in our galaxy where feedback takes place, and at distant galaxies containing millions of stars to see how feedback plays out at large scales and in different environments.
A tunable laser including: a reflecting mirror; a partially transmitting mirror; a gain medium energized by a pump source; a pair of mirrors surrounding the gain medium, a first prism and a second prism located between the gain medium and the reflecting mirror; the first prism receives radiation from the gain medium and disperses the radiation to the second prism; the second prism receives and directs the radiation towards an optical element which filters the spatially dispersed radiation based on the position to the second prism, the radiation resonates between the reflecting mirror and the partially transmitting mirror; the second prism is placed on a stage moved by a linear motor such that a desired center wavelength is obtained by moving the second prism to a position so as to allow radiation having the desired center wavelength to resonate between the reflecting mirror and the partially transmitting mirror.

And greed, again, and the blind lust of honors 2956Which force poor wretches past the bounds of law, 2957And, oft allies and ministers of crime, 2958To push through nights and days of the hugest toil 2959To rise untrammeled to the peaks of power- 2960These wounds of life in no mean part are kept 2961Festering and open by this fright of death. 2962For ever we see fierce Want and foul Disgrace 2963Dislodged afar from secure life and sweet, 2964Like huddling Shapes before the doors of death. 2965And whilst, from these, men wish to scape afar, 2966Driven by false terror, and afar remove, 2967With civic blood a fortune they amass, 2968They double their riches, greedy, heapers-up 2969Of corpse on corpse they have a cruel laugh 2970For the sad burial of a brother-born, 2971And hatred and fear of tables of their kin. 2972Likewise, through this same terror, envy oft 2973Makes them to peak because before their eyes 2974That man is lordly, that man gazed upon 2975Who walks begirt with honor glorious, 2976Whilst they in filth and darkness roll around; 2977Some perish away for statues and a name, 2978And oft to that degree, from fright of death, 2979Will hate of living and beholding light 2980Take hold on humankind that they inflict 2981Their own destruction with a gloomy heart- 2982Forgetful that this fear is font of cares, 2983This fear the plague upon their sense of shame, 2984And this that breaks the ties of comradry 2985And oversets all reverence and faith, 2986Mid direst slaughter. For long ere to-day 2987Often were traitors to country and dear parents 2988Through quest to shun the realms of Acheron. 2989For just as children tremble and fear all 2990In the viewless dark, so even we at times 2991Dread in the light so many things that be 2992No whit more fearsome than what children feign, 2993Shuddering, will be upon them in the dark. 2994This terror, then, this darkness of the mind, 2995Not sunrise with its flaring spokes of light, 2996Nor glittering arrows of morning sun disperse, 2997But only Nature's aspect and her law.
If men, in that same way as on the mind 4184They feel the load that wearies with its weight, 4185Could also know the causes whence it comes, 4186And why so great the heap of ill on heart, 4187O not in this sort would they live their life, 4188As now so much we see them, knowing not 4189What 'tis they want, and seeking ever and ever 4190A change of place, as if to drop the burden. 4191The man who sickens of his home goes out, 4192Forth from his splendid halls, and straight returns, 4193Feeling i'faith no better off abroad. 4194He races, driving his Gallic ponies along, 4195Down to his villa, madly,- as in haste 4196To hurry help to a house afire.- At once 4197He yawns, as soon as foot has touched the threshold, 4198Or drowsily goes off in sleep and seeks 4199Forgetfulness, or maybe bustles about 4200And makes for town again. In such a way 4201Each human flees himself- a self in sooth, 4202As happens, he by no means can escape; 4203And willy-nilly he cleaves to it and loathes, 4204Sick, sick, and guessing not the cause of ail. 4205Yet should he see but that, O chiefly then, 4206Leaving all else, he'd study to divine 4207The nature of things, since here is in debate 4208Eternal time and not the single hour, 4209Mortal's estate in whatsoever remains 4210After great death. 4211And too, when all is said, 4212What evil lust of life is this so great 4213Subdues us to live, so dreadfully distraught 4214In perils and alarms? one fixed end 4215Of life abideth for mortality; 4216Death's not to shun, and we must go to meet. 4217Besides we're busied with the same devices, 4218Ever and ever, and we are at them ever, 4219And there's no new delight that may be forged 4220By living on. But whilst the thing we long for 4221Is lacking, that seems good above all else; 4222Thereafter, when we've touched it, something else 4223We long for; ever one equal thirst of life 4224Grips us agape. And doubtful 'tis what fortune 4225The future times may carry, or what be 4226That chance may bring, or what the issue next 4227Awaiting us. Nor by prolonging life 4228Take we the least away from death's own time, 4229Nor can we pluck one moment off, whereby 4230To minish the aeons of our state of death. 4231Therefore, O man, by living on, fulfill 4232As many generations as thou may: 4233Eternal death shall there be waiting still; 4234And he who died with light of yesterday 4235Shall be no briefer time in death's No more 4236Than he who perished months or years before. 2ff7e9595c
