Cygnus completes mission to 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.

Cygnus has successfully completed its cargo mission to ISS, burning up upon re-entry on Sunday.

The story includes images of the re-entry taken by astronauts on ISS.

    It is noteworthy that Cygnus and Dragon are taking the role of the now discontinued European ATV (the current flight being the last). After several companies competed with each other during the COTS portion of the program, these two companies won the Commercial Resupply Services contracts.

    The ATV program took about 55,000 lbs to the ISS and cost $5 billion. During their CRS contract periods, Cygnus can take about 16,000 lbs (2,000 lbs per flight) for a cost of $2 billion, and Dragon can take 84,000 lbs (7,000 lbs per flight) for a cost of $1.6 billion (or $2 billion, if you choose to include development costs).

    It looks like the commercial companies, which are new to this type of business, are already performing about as well as the older government agencies. Ain’t competition a nice thing?
