SDO Day 93: SDO Becomes an Operating Mission

SDO was declared an operational mission today at the Goddard Space Flight Center. This means we have shown the spacecraft and instruments are ready to collect science data. The science teams are working on making that data available to the scientists and space-weather public.

SDO Day 89: Our Next Poem

We have had haikus and sonnets written about the commissioning phase. Now a First Light poem, written by Stuart Atkinson about the prominence eruption on March 30, 2010.

First Light...
And at last, the secret of our solar system's star has been revealed:
Concealed beneath its brightly shimmering, ever-shifting shells
Of ancient hydrogen a mighty dragon lies; planet-sized
Eyes flashing with photon fire, riding the great plasma tides
Boiling up from Sol's deep core, it roars in raw delight,
Feeding on the brutal fusion light throbbing beneath its feet...
Hiding in the Sun's dark heart it bathes in nuclear fire,
Revelling in its fury, rolling in it, each beat of its wings
Sending great waves of energy slamming up into the
Chromosphere to ripple and roil across Sol's surface
In tsunamis of atomic fire, to the amazement of those watching,
Wide-eyed, on Faraday's far-away Earth...
But these images reveal the dragon is not alone;
The Sun's firestorm fields clearly have shielded
Our prying eyes from flocks of phoenixes flying
In the dragon's wake. Each time a starfirebird bursts
Through the seething surface of our star we see
A glorious prominence leaping into space;
Every feathered, towering arch traces out the path
Of a phoenix's graceful rise and fall.
Each time one manages to break free
Of the Sun's greedy gravity we see a
Fiery red banner billow out, tatter and tear,
Flapping away like it had never been there...
