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.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

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.
