They got a 50% deal. From the article:

"At least NASA seems to have bagged a good deal from AWS: The Register used Amazon’s cloudy cost calculator to tot up the cost of storing 247PB in the cloud giant’s S3 service. The promised pay-as-you-go price for us on the street was a staggering $5,439,526.92 per month, not taking into account the free tier discount of 12 cents. The audit, meanwhile, suggests an increased cloud spend of around $30m a year by 2025, on top of NASA’s $65m-per-year deal with AWS."

$5.4m/mo * 12 mo/yr = $65m/yr. My guess is the "$65m/year deal with AWS" is actually the S3 cost and the extra $30m/year of 'increased cloud spend' is the egress costs found by the audit. Otherwise it's a coincidence of the numbers.
