he commanded the mission that deployed the hubble space telescope. general bolden created the space technology mission directorate. his tenure at nasa has seen the landing of the mars curiosity rover. and an increase of earth observation satellites. he earned his bachelors of science from the u.s. naval academy and his masters in system management from the university of southern california. join me in welcoming charlie bolden. (applause) >> just as i did yesterday, i want to call out a couple of people who really played a critical role in my development but also in the time i spend as the nasa administrator. there is a guy in the room who has helped everything we have done in human spaceflight in the last 20 years. i don't know whether bill is still here. did he leave? ok? one of the things i learned a long time ago when i can to the naval academy and again when i came became a marine, they said listen to the gunny. or listen to the chief. that means you have very smart people who happen to not be officers. if you listen to them, they will not steer y

discovery, led by professorjoss bland—hawthorn from australia, used the data gathered by the hubble space telescopeignificant. when gas clouds and stars fall into the centre of the galaxy, they go into a death spiral around the central black hole — we have an enormous black hole at the centre of our galaxy, four million times the mass of our sun. the black hole itself is invisible, but this spiral of gas going around the centre of the black hole gets very, very hot indeed, then blows off jets, winds and bubbles into the surrounding galaxy. so, what we‘ve seen is evidence of the explosion 3.5 million years ago, a giant beam of radiation, like a lighthouse beacon flashed from a galactic centre and went right across the galaxy and lit up gas a long with out from the centre of our galaxy. we just saw some pictures there to give us a sense of what this is, but given this is at the centre of the galaxy and given that earth is far away from it, are we any danger of this flare and what it‘s producing? it‘s a very good question, because our black hole, in fact, the disc around the black hole does flop aroun

the shuttle made it possible to fly payloads like the hubble space telescope any of the great observatories that have revolutionized our knowledge of the universe. and it also made possible the building of the international space station, which is an engineering marvel that is still up to doing its job. in summary, i think the spatial program is something we'll look back on fondly. it would be a long time before ever see a vehicle that's that's anywhere near as capable of that. and i was sorely disappointed when, in 2011, the program was terminated. i'm anxious to have the star liner and the dragon topsails are going to correct the problem person, so thank you.
