Redesigned Antares launch scheduled for Oct 13
NASA and Orbital ATK have now set October 13 as the date for the first Antares launch in two years.
Though ISS is not short of supplies, this quote underlines the difficulty of the particular situation now.
While the space station has plenty of food, water, experiments and other provisions, NASA officials are eager for the Antares rocket to resume flights as all of the research outpost’s other servicing vehicles are facing delays.
SpaceX’s Falcon 9 rocket, which launches the company’s Dragon cargo craft, is grounded after a launch pad explosion Sept. 1, and Dragon resupply missions to the space station may not start up again until early next year.
The Japanese HTV cargo freighter was supposed to blast off Sept. 30 with several tons of supplies, including new lithium-ion batteries for the space station’s electrical system. But that launch has been delayed until at least December after Japanese engineers discovered a leak during an air tightness test in August.
And a Soyuz crew capsule that was supposed to launch Sept. 23 with three new space station residents will not lift off until at least Oct. 19 after Russian workers discovered a technical problem on the vehicle. The Soyuz delay will likely push back the launch of Russia’s next unpiloted Progress cargo freighter from Oct. 20 until late November or early December.
Even with numerous redundent methods for hauling cargo to ISS, it is still possible for them all to have problems all at once.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

They say that a rocket is designed around its engines, so it is interesting that they switch engines. The RD-191 is a derivative from NK-33, but over a couple of generations and half a century. The physical dimensions are different. Diameter 1½ vs 2 meter, weight 2.2 vs 1.2 ton, length 4 vs 3.7 meter. The newer motor is much more compact per weight. 25% higher thrust probably affects many things in the rocket. I wonder if something similar has been done historically. Virgin Galactings attempt to scale up its composite motor led to problems and reduced specs.
