MEDIA ADVISORY M20-130
NASA TV Coverage Set for Next Space Station Resupply Mission with SpaceX
NASA commercial cargo provider SpaceX is targeting 11:39 a.m. EST Saturday, Dec. 5, for the launch of its 21st commercial resupply services (CRS-21) mission to the International Space Station from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. CRS-21 will deliver science investigations, supplies, and equipment for NASA and is the first mission under the company’s second Commercial Resupply Services contract with NASA. Live coverage will air on NASA Television and the agency’s website, with prelaunch events Friday, Dec. 4, and Saturday, Dec. 5.
The upgraded Dragon spacecraft will be filled with supplies and payloads, including critical materials to directly support dozens of the more than 250 science and research investigations that will occur during Expeditions 64 and 65. In addition to bringing research to the station, the Dragon’s unpressurized trunk will transport the Nanoracks Bishop Airlock. The first commercially funded space station airlock, the Bishop Airlock is an airtight segment used for transfer of payloads between the inside and outside of the station. It provides payload hosting, robotics testing, and satellite deployment while also serving as an outside toolbox for astronauts conducting spacewalks.
About 12 minutes after launch, Dragon will separate from the Falcon 9 rocket’s second stage and begin a carefully choreographed series of thruster firings to reach the space station. Arrival to the space station is planned for Sunday, Dec. 6. Dragon will autonomously dock to the station’s Harmony module with Expedition 64 Flight Engineers Kate Rubins and Victor Glover of NASA monitoring operations.
The Dragon spacecraft will spend about one month attached to the space station before it returns to Earth with research and return cargo, with splashdown in the Atlantic Ocean.
Full mission coverage is as follows (all times Eastern):
Friday, Dec. 4
2 p.m. – One-on-one media opportunities with principal investigators for payloads on CRS-21 at the Kennedy Press Site (compliant with COVID-19 safety protocols).
TBD – Prelaunch news conference from Kennedy with representatives from NASA’s International Space Station Program, SpaceX, and the U.S. Air Force’s 45th Space Wing. For the dial-in number and passcode, please contact the Kennedy newsroom at [email protected] no later than 3 p.m. Friday, Dec. 4.
Saturday, Dec. 5
11:15 a.m. – NASA TV launch coverage begins for the 11:39 a.m. launch.
Sunday, Dec. 6
9:30 a.m. – NASA TV coverage begins for Dragon docking to space station
11:30 a.m. – Docking
The deadline for media to apply for accreditation for this launch has passed, but general information about media accreditation is available by emailing [email protected].
Members of the public can attend the launch virtually, receiving mission updates and opportunities normally reserved for on-site guests. NASA’s virtual launch experience for CRS-21 includes curated launch resources, a behind-the-scenes look at the mission, notifications about NASA social interactions, and the opportunity for a virtual launch passport stamp following a successful launch.
To participate, members of the public can register for email updates or RSVP to the Facebook event for social media updates to stay up-to-date on mission information, mission highlights, and interaction opportunities. To find out more, visit:

After liftoff, the rocket's first stage will return to the Cape's Landing Zone 1 and generate three sonic booms just before touchdown.
Emre Kelly says CRS-21 will be a RTLS launch. I’m not so sure about this. -

... and filings indicating ASDS.
Specifically here on the Paperwork thread, where strawwalker and gongora link two FCC applications for "Mission 1410", one listing ASDS operation and the other describing it as a CRS mission. -

Question for the experts: does the Bishop Airlock take up the entire trunk, or is it smaller than the trunk space?
I figure that Bishop’s length is determined by the available space at the end of Node 3, not the trunk size of Dragon. It would be a minor miracle if the space at the end of Node 3 were the same length as the Dragon trunk.
I found some slides showing how it fits into the trunk. Plenty of room.

Do we have a confirmed mass for Bishop yet?
You’ve cited 1,059kg before and I tend to believe figures from the manufacturer on this.

I found some slides showing how it fits into the trunk. Plenty of room.
Note that the slides are out of date and still show the D1 trunk. D2's Trunk does not have the narrowing for the solar panels / the intrusions for the joints so there is actually additional X + Y axis room. Much more clearance for Dextre to reach in and grab it.
However, for Z axis, there are 2 restrictions: Dragon's trunk (the ample visual clearance to the end of Dragon's trunk is actually pretty tight on the keep out envelope for F9's 2nd stage) and Node 3's clearance to the radiator (18" at the closest point per NanoRack).
Brickmack also found an interesting patent where NanoRacks is considering an add on the airlock with a cylindrical extension.
This to me denotes that Nanoracks wanted a larger monolithic Bishop but needed to break the airlock into 2 payloads due to launch vehicle constraints (and I'm sure for a variety of other reasons as well).Do we have a confirmed mass for Bishop yet?
You’ve cited 1,059kg before and I tend to believe figures from the manufacturer on this.
I actually reached out to NanoRacks directly, but after some back and forth they declined to comment on the mass of the airlock. I guess we will have to wait for NASA to publish the official unpressurized mass like they normally do a couple days before flight. Still mainly interested from the perspective of the new max unpressurized payload mass of D2 and if it changed between D1 and D2.

Well that seems pretty official
Bishop airlock 1090 kg
Speculation time: is the extra 30kg (from NR's original 1060kg figure) explained away by the cbm passive target or is it just the newly reported mass of the airlock?
It also looks like the OIGs reporting of D2 unpressurized capabilities are now proven to be factually incorrect based on these numbers.
Maybe that's why they chopped off 2 of the fins from the trunk to make it uphill this time. /s -

Note that the actual document (not all pages shown) list the 1090 figure as including the installation hardware (not included is the internal outfitting hardware that is installed after berthing). 1090 is the total combined mass.Well that seems pretty official
