On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs." --San Antonio Express-News
After spending a month dropping down deep into Venus’s atmosphere, engineers are now raising Venus Express’s orbit.
Thus routine science operations concluded on 15 May, and the spacecraft’s altitude was allowed to drop naturally from the effect of gravity, culminating in a month ‘surfing’ between 131 km and 135 km above the surface. Additional small thruster burns were used to drop the spacecraft to lower altitudes, reaching 130.2 km earlier this week. Tomorrow, it is expected to dip to 129.1 km.
After eight years orbiting Venus, the mission is finally ending. They will use the spacecraft’s thrusters to lift it back up to almost 500 kilometers, where they will then allow its orbit to naturally decay, eventually ending the mission when it burns up in the atmosphere. There is also the chance they will run out of fuel during these last burns, ending the mission slightly sooner.
We are now in the third week of my annual July fund-raiser for Behind the Black. My deep thanks to everyone who has so far donated or subscribed. The response this year has been wonderful.
We are not done yet. This monthly fund-raiser is now half over, and I am hoping the second half will result in as many donations as the first half did. If it does, I will remain free to continue my writing as I see fit, unblemished by the efforts of others to squelch my perspective in this increasingly intolerant world.
This year's fund-raising drive is also significant in that it celebrates the 10th anniversary of this website's founding. It is hard to believe, but I have been doing this for a full decade, during which I have written more than 22,000 posts, of which more than 1,000 were essays and almost 2,600 were evening pauses.
Therefore, I hope you will please consider donating to Behind the Black, by giving either a one-time contribution or a regular subscription, as outlined in the tip jar below. Your support will allow me to continue covering science and culture as I have for the past twenty years, independent and free from any outside influence.
Regular readers can support Behind The Black with a contribution via paypal:
