Astronaut Shannon Walker works in the Columbus laboratory module

iss064e019119 (Jan. 4, 2021) --- NASA astronaut and Expedition 64 Flight Engineer Shannon Walker works in the European Columbus laboratory module to set up a unique device that calculates the mass of cargo aboard the International Space Station. Known as SLAMMD, or Space Linear Acceleration Mass Measurement Device, it uses a form of Newton's Second Law of Motion and applies a known force to an object or an astronaut with the resulting acceleration used to calculate mass in microgravity

The CTB adapter for SLAMMD (built by SpaceX) is being used to weigh cargo bags as CRS-21 continues to be loaded with downmass. The adapter was first tested in ~~May 2020~~ end of 2019.

According to https://www.n2yo.com/, the ISS pass on Monday night just after 9pm is from south-west gulf to north-east off the coast from Jacksonville. I assume the Dragon will be on a similar ground track. I live just south of the space center. If it splashes in the Atlantic at any of the recovery zones, I'm wondering what the possibility is of seeing the re-entry fireball? Or is is already cooled enough by the time it gets over Florida that it will be invisible?

I apologize for this noob question as I am almost certain this has been answered before, but somehow I screwed myself with the search engine.

Can someone clarify why Dragon 1 wasn't able to return to East Coast for fast science?

Overflight permission to cross Florida west-to-east en route to recovery zone took a while to earn. Had to demonstrate precision targeting.

That's as much as I know. Perhaps others here can fill in more details.

Departure!

Dragon recovery ship GO Searcher is outbound from Port Canaveral for the CRS-21 splashdown!

Dragon is set to splashdown at approx 9pm ET tommorow, Jan 11th.

CAPCOM reported during the DPC that Space X and the orbit 1 team are on duty to support Dragon final pack, undock, and landing.

Targeteer · « **Reply #392 on:** 01/11/2021 08:42 am »

A very interesting exchange on the voice loop. The crew is currently working to pack cold storage items for placement in Dragon. There are apparently multiple lists, instructions, and notes for the same task. CAPCOM passed many of the pictures and text in one document do not match the ground versions and are flat wrong, and Houston has no clue why. After explaining that to the crew, Kate came on very forcefully told the ground that they will not concurrently work filling double cold bags and stowing them in Dragon. The multiple, contradictory sources of instructions with numerous corrections force them to focus on one task at a time. Her last statement, again forceful, to Houston was "Does everyone understand?" The somewhat tepid response was "Houston copies and agrees." This is not the first time the crew has voiced displeasure with the grounds efforts to micromanage tasks with multiple documents..

Would these confusing lists and instructions be coming from SpaceX or from NASA? NASA would of course be the ones deciding what is going into Dragon, but SpaceX maybe has a say in where it goes due to weight distribution?

Is there any sort of timeline out of when entry interface begins? Wanted to go outside my house in Tampa and look up tonight!

I can't see how it would be anyone BUT NASA. SpaceX is a supplier, and while they provide weight and balance info to NASA for Dragon, only NASA manages ISS, and this is an ISS tasking. You can also tell that by the fact that the communications are from Houston, not Hawthorne.
