The Crew Dragon is due to depart the ISS on 8 March, 2019 around 07:30 UTC (02:30 EST),
before heading to a splashdown in Atlantic, off the Florida coast.

SO, run your ISS tracking program (or use “on-line” versions) starting on March 8th.
You will find an ISS pass (51.6° inclination) that crosses near the recovery area.
Crew Dragon Splashdown will be on Friday Morning at ~ 8:45 AM

Crew Dragon, March 8 schedule
2 a.m.: NASA TV coverage of Dragon undocking begins.
2:31 a.m.: Undocking from ISS
7:53 a.m.: Deorbit Burn
8:45 a.m.: Splashdown

Just to clarify: The capsule should pass within minutes of the ISS following the same ground track but will of course be much lower on the horizon, guesstimating about 1/4 the visibility radius unless someone knows better...

GO Searcher departed Port Canaveral for the DM-1 Dragon LZ a few hours ago. GO Navigator is still in Port at this time.

Reentry on Friday will be on a Descending Node, with Crew Dragon cutting across North America from Vancouver, British Columbia to Georgia in the pre- and post-dawn hours (depending on location) as she heads towards splashdown off the east coast of Florida.

Those under the flight path (the orange line in this image) might have the opportunity to see reentry if conditions are right.

Earth’s 3rd day started with getting the blood (plasma?) pumping! First the treadmill, then weights - he even got some deadlifts in with me. It is important to exercise every day, not just for our muscles but also to protect our bones from losing density in microgravity.

I'm loving this.

Earth to Space Station: White House Phones Crew

Anna Heiney Posted on March 6, 2019

The SpaceX Crew Dragon continues to perform well more than halfway through the Demo-1 flight test. Currently docked to the International Space Station’s Harmony module, the spacecraft is performing an end-to-end demonstration of its capabilities during the company’s first flight with NASA’s Commercial Crew Program.

Vice President Mike Pence provided a boost to the station’s crew with a congratulatory call on Wednesday afternoon.

“It was inspiring to see the launch. It was even more inspiring to see the docking and to see you open that door and float into that spacecraft knowing that we’ll very soon have American astronauts aboard,” Pence said, adding that the Demo-1 mission is evidence of the United States’ renewed commitment to leadership in space.

“Witnessing Dragon docking was a real honor; we feel very privileged to have been a part of it,” NASA astronaut Anne McClain answered. “There’s an intersection of practical and magical. In the back of our mind we knew how significant it was and how important it was for the whole history of spaceflight.”

A SpaceX Falcon 9 rocket boosted the Crew Dragon into orbit with a brilliant predawn liftoff on Saturday, March 2, from Launch Complex 39A at NASA’s Kennedy Space Center in Florida. The spacecraft caught up to the space station on Sunday, March 3, successfully docking to the orbiting laboratory at 5:51 a.m. EST. NASA astronaut Anne McClain, David Saint-Jacques of the Canadian Space Agency, and Russian cosmonaut and Expedition 58 commander Oleg Kononenko opened the Crew Dragon’s hatch at 8:07 a.m.

Strapped into one of the spacecraft’s seats is Ripley, a lifelike test device outfitted with sensors to provide important data about what humans traveling on Crew Dragon will experience. The spacecraft also ferried 400 pounds of crew supplies and equipment to the station.

The Crew Dragon hatch will be closed tomorrow afternoon at approximately 12:25 p.m. The spacecraft will remain docked to the space station until approximately 2:30 a.m. on Friday, March 8. The spacecraft is expected to return to Earth hours later, with a splashdown in the Atlantic Ocean at approximately 8:45 a.m. These milestones will be broadcast on NASA TV.

The Demo-1 mission marks a significant step toward returning to the nation the capability to launch astronauts on a U.S.-built spacecraft from U.S. soil, as well as the potential to expand the station’s capability for microgravity research.

Vice President Calls Station, Crew Dragon Packed for Friday Return

Mark Garcia Posted on March 6, 2019

Vice President Mike Pence and NASA Administrator Jim Bridenstine called up to the Expedition 58 crew today. Astronauts Anne McClain and David Saint-Jacques were on hand to talk about their mission success and the arrival of the first Commercial Crew vehicle, the SpaceX Crew Dragon.

The Crew Dragon is being packed and readied for its return to Earth on Friday. In the midst of NASA’s first Commercial Crew mission, the crew members continued more space research and practiced an emergency drill today.

Saint-Jacques of the Canadian Space Agency transferred cargo in and out of the Crew Dragon today. Over 300 pounds of science gear, crew supplies and station hardware will be retrieved from Dragon after it returns to Earth.

The Crew Dragon will undock Friday at 2:31 a.m. EST from the Harmony module’s international docking adapter. It will parachute to a splashdown in the Atlantic Ocean around 8:45 a.m. EST. NASA TV will cover all the activities live.

McClain from NASA worked in the Destiny laboratory module today stowing science hardware after working on the Microgravity Sciences Glovebox. She then began collecting and readying more experiment hardware that will test ways to improve the production of higher-quality semiconductor crystals.

Both astronauts then joined Commander Oleg Kononenko from Roscosmos to practice an emergency evacuation of the International Space Station. The trio wore breathing masks, entered the docked Soyuz spacecraft and prepared for a return to Earth in the unlikely event of a critical emergency aboard the orbital complex.

DM1 Dragon reentry visibility over the United States

After a day of leading the charge to find an answer to this question, here's what we can notionally expect on Friday morning during the DM-1 Dragon's reentry and splashdown.  Note: this is what is expected IF lighting, sun angle, and cloud cover are all absolutely perfect.  There is no way to actually know what we will see as this is the first time Crew Dragon is performing a reentry and splashdown - so caution and a bit of "this is a test" attitude is needed here.

The Pacific Northwest (including all of southern British Columbia) as well as Idaho, northern Utah, western Montana, and southern Alberta Province - given clear skies - might be able to see Dragon AFTER her deorbit burn but BEFORE reentry.  She will - if you can see her - appear as a very faint, fast moving dot in the night sky traveling IN FRONT OF the International Space Station.  Once you see the Station, you will have missed Dragon.  Look closely.  She'll be faint - and viewing will be dependent on her orientation and reflectivity as she comes overhead.  Just because you're under the ground track, doesn't guarantee you'll be able to see her.

Pacific Time Zone:
Viewing: just before 05:27 am PST (go outside about 7mins before this time)
Vancouver, BC and southern British Columbia Province
Bellingham, WA
Seattle, WA
Portland, OR
And places near and in-between them as well as most of Washington state and most cities in northern Oregon.

Mountain Time Zone:
Viewing: just before 06:28 am MST (go outside about 7mins before this time)
Boise, ID
Calgary, Alberta
Helena, MT
Idaho Falls, ID
Salt Lake City, UT
Most cities in northern Utah, almost all of Idaho, and western Montana

No viewing is expected along the ground from Wyoming and central Montana southeast across the U.S. to Georgia.

Georgia, southeastern South Carolina and northeastern portions of Florida:
Here's where it gets tricky.  Those in these areas of the United States might, and I do stress might be able to see Dragon's reentry and the plasma stage of that event.  This will be highly dependent on cloud cover in your region, viewing angle, and intensity of Dragon's plasma flow.  It is NOT a guarantee that you'll be able to see it; it's just a possibility that you might.

Dragon will be flying to the southeast nearly directly into a risen Sun.  This will make viewing challenging, but not impossible.

Entry interface is at 8:33:58 am EST.  Shortly thereafter, plasma will envelop Dragon as she slams into the dense lower atmosphere.

Unlike Shuttle, the plasma stage of reentry will not last long.  Only a few short minutes (like Soyuz, actually).

Parachute deployment (which is not expected to be visible to anyone on land) is scheduled for 8:41 EST well off the east coast of Florida.

Splashdown is scheduled for 8:45 am EST.
