Cmrcl crew and cargo lowered it compared to shuttle, but not as much as ppl hoped. Wanted factor of 10 reduction, but only 20-40% based on what I've seen.Rather surprised by those numbers. Is he including commercial crew development costs too? Or basing it on total payload / something else? Individual crew flights are clearly significantly less than a shuttle flight, although not by an order of magnitude.Money paid, or that will be paid, to SpaceX by NASA for Commercial Crew. CCDev 2 (2011) $ 75 million CCiCap (2012) $ 440 million CPC phase 1 (2012) $ 10 million CCtCap (2013) $ 2600 million -------------------------------------- Total (2025) $ 3125 millionBut it's important to realize that SpaceX has not received $3.125 billion from NASA. CCtCap's $2.6 billion includes a commitment by NASA to buy six commercial crew missions at a fixed price of $220 million per mission. But this money is only paid out as the missions occur (see Wikipedia, Commercial Crew Development, 2020-6-9).Thus as of today SpaceX has received $1.255 billion from NASA for the development of its Commercial Crew capability. The remaining $1.320 billion will be paid out mission by mission with the last mission and payment in 2025.In addition to the money that NASA has paid or will be paying to SpaceX there is the money NASA spent internally to support the effort. There would be, I would guess, quite a few people on NASA's payroll that have aided, inspected, supervised, and certified SpaceX's Commercial Crew program. To do a true comparison of the cost of Commercial Crew (SpaceX) to the Space Shuttle program we need to know that number.

Phil McAlister discussed CCtCap-2 at yesterday's NAC HEO meeting.https://twitter.com/genejm29/status/1349419794370617346See slide 16:https://www.nasa.gov/sites/default/files/atoms/files/nac_-_csd_update_-_jan_2021_v3.pdf
Also coming up to re post the commercial crew and cargo contracts ... want some abilities that we don't have with current providers.

This isn't equivalent to the STS shutdown and even a veiled reference to that seems boorish and insensitive at best.
NASA opened a new synopsis for an "International Space Station Seat Exchange," meaning a deal between NASA and Roscosmos is officially in the works to fly a Russian on Crew Dragon or Starliner, in exchange for a backup seat on a Soyuz spacecraft.
NASA Wants A Soyuz Seat This Spring As Backup Plan

There is no need to buy any more seats. Sounds like Russia doesn't want to give up the fat paycheck. They should just seat swap already, if not don't do it. I guess NASA is afraid Russia will sell a seat to China or help China with their new space station.
Members of the Hawaii Air National Guard's 204th Airlift Squadron wrapped up a month-long search and rescue exercise throughout and around Oahu on Feb. 6, alongside partners from the Alaska ANG....During each manned voyage, such as SpaceX's launches to the ISS in May and November last year, airlift Airmen staged rescue packages in Hawaii and South Carolina. In the event of a hard-to-reach water landing, the closer C-17 will locate the capsule, airdrop watercraft, along with a team of pararescue members, who are prepared to egress and treat the astronauts for up to 72 hours."If astronauts splash down within 200 miles of the launch site, a rescue triad is on alert to respond," said Maj. Joseph Leman, 144th AS instructor pilot and exercise director. "If the landing is beyond that radius, a C-17 becomes the aircraft of choice for the mission because we can go further and get there faster."
