The 50th anniversary of Gagarin’s spaceflight

I am on the road today, so posting will be light. Though I have many things to say about today’s historic anniversary, fifty years after the first manned spaceflight by Yuri Gagarin, I simply won’t be able to post them. However, I plan to express some of my thoughts on the John Batchelor Show at 11:30 pm (Eastern time) tomorrow. Listen in live, or on his podcast posted shortly after the live show.

The ironies, however, are amazing, and quite depressing. On the same day we celebrate the start of manned space exploration, NASA administrator Charles Bolden will announce where the United States’s three retired shuttles will be put on display. Note also that he does this on the thirtieth anniversary of the first shuttle flight. It is almost as if the Obama administration’s desire to kill the American government space program is so strong that they have to rub salt in the wound as they do it.

I say this not so much because I am in favor of a big government space program (which I am not) but because the timing of this announcement once again illustrates how astonishingly tone-deaf the Obama administration continues to be about political matters.

Newly discovered asteroid orbits in union with Earth

Newly discovered asteroid follows the Earth as it orbits the Sun, and has been doing it for a quarter million years.

Currently, three other horseshoe companions of the Earth are known to exist but, unlike 2010 SO16, these linger for a few thousand years at most before moving on to different orbits. Also, with an estimated diameter of 200–400 metres, 2010 SO16 is by far the largest of Earth’s horseshoe asteroids. The team has already used the Las Cumbres Observatory’s Faulkes Telescope in an on-going campaign to track the object and refine its orbit further. “It is not that difficult to spot with a medium-sized professional telescope”, says Dr Asher. “It will remain as an evening object in Earth’s skies for many years to come.”
