@ sisfreak2017 - 10.09.17 - 04:29pm SpaceX launches the X-37B us air force secret shuttle few days ago but the spaceX return vehicle videos pretty neat http://m.liveleak.com/view?i=a70_1504810844 It's not a secret, if it was they wouldn't announce when, where and by whom it is being launched. It's just what it actually does up there and what, if any, payloads it is carrying that are classified. It's last mission lasted for 2yrs, from May 2015 to May this year. |

NASA's OSIRIS-REx spacecraft is flying past Earth today, Sept. 22nd, using our planet's gravity to fling itself toward a potentially hazardous asteroid named 'Bennu'.At closest approach, OSIRIS-REx will be only 10,711 miles above Earth's surface, inside the orbit of geosynchronous satellites. This map shows the circumstances of the encounter: |

NASA is visiting Bennu ... before it visits us.Bennu crosses Earth's orbit every six years. In 2135, the asteroid may enter a 'keyhole' between the Earth and the Moon where the gravitational pull of our own planet will tweak Bennu's orbit, potentially putting it on course for Earth later that century. Currently, the odds of a collision 150+ years from now are no more than about 1 in 2700--small, but enough to prompt an 800 million space mission. Arriving in late 2018, OSIRIS-REx will spend more than a year flying in close proximity to Bennu using five instruments to survey the asteroid. The resulting maps will pinpoint a safe sampling site, where the probe can each out with a mechanical arm and gather material from the asteroid's surface. If all goes as planned, samples will be returned to Earth in the Fall of 2023, when a capsule containing bits of Bennu will land at the Utah Test and Training Range. |

@ obi_jon - 18.09.17 - 09:23pm Horizon Cassini special on BBC2. Can you get the BBC in Ireland? I missed the first 10mins, didn't know about it. I'll catch it on youtube eventually. |

@ sisfreak2017 - 22.09.17 - 06:16pm there's probably loads like this that'll prob only officially exist once they actually hit us not us but some Vast ''UnderPopulated'' country on earth. If one that size hit us, it wouldn't really matter where the impact was, vast 'underpopulated' country, or not. The amount of debris flung into the atmosphere would plunge the earth into a devastating worldwide disaster, blocking out sunlight and causing drastic global cooling, like a 'nuclear winter', possibly lasting decades. Crops would fail, food supplies would run out, many, many millions or probably even billions would die, bringing us to the edge of extinction as a species. Presumably some people would be able to take shelter in underground nuclear bunkers but even they wouldn't be safe from a direct hit in their immediate vicinity. Anyone that survived the initial impact by virtue of being far enough away from it, would face years of worldwide freezing temperatures and subsequent starvation. Civilized society would simply collapse. If it where to happen, I think i'd rather be at ground zero. At least that way death would be quick, rather than having to face the unimaginable suffering and almost certain death from the nightmarishly brutal conditions that would inevitably occur afterwards. |
