Lockheed Martin enters the competition to supply cargo for ISS


Readers!
 
For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
 
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

The competition heats up: Lockheed Martin has joined Sierra Nevada, Orbital ATK, Boeing, and SpaceX in bidding for NASA’s next contract to ferry cargo to ISS.

Lockheed’s proposal is different in that it proposes a two spacecraft operation. The cargo would be hauled up in a very simple storage bin, where a long-term orbital tug would grab it and take it to ISS. The idea is that they would only have to build and launch the complicated thrusters, robot arms, computers, and avionics of their cargo freighter once, thereby saving money.

Two companies will be chosen. Since the first competition back in the mid-2000s, when NASA picked SpaceX and Kistler for the first cargo round, the quality of the bids has improved remarkably. Back then, NASA had to choose from a bunch of new companies, none of which had ever done this before. The big companies (Boeing, Lockheed Martin) then poo-pooed the competition, saying that it couldn’t be done as cheap as the new companies claimed. After Kistler went under and was replaced by Orbital, they and SpaceX proved the big companies were wrong.

Now the competition includes all the big players, except that those big players are no longer offering expensive systems but cut-rate efficient designs that are as cost effective as SpaceX and Orbital’s first designs.

    It is pretty cool but I don’t like how they deorbit the cargo mods. It would be better if there was a way to do this without losing the centaur stage. I guess the proposed idea is an incremental improvement as in the centaur costs less than the tug portion but…

    It might work if the cargo module brings up its own fuel plus a little extra. Any left over could be pumped onto the station for its use a then the tanks could be purged(vented) to space.

    The fuel would have to hydrogen and oxygen though. It could be turned into water or the O2 could just be used for breathing.
