Public confirmation is here for a NET 2 March launch:
https://fcc.report/ELS/Space-Exploration-Technologies-Corp/0068-EX-ST-2019?fbclid=IwAR3W9pOtBy9hrusZ1T7gXoMWzEDUQ2sU3LaDR9ojHGEFWppXLEjNWd6PbAk

Unless I am missing something, that is not confirmation of any NET. SpaceX is just bumping the previous license which was going to expire on March 1st. Technically, they could still launch on March 1st using the previous permit. All this really says is that SpaceX thinks there is a chance that the launch may slip past March 1st.

MOSCOW, January 31 - RIA News. The next launches of the American spacecraft to the ISS are postponed to a later date, a source in the Russian rocket and space industry told RIA Novosti on Thursday.
Earlier, another source told RIA Novosti that the launch of SpaceX Ilon Mask developed by the Dragon-2 spacecraft to the ISS in unmanned mode was postponed from the end of February to the first half of March.
“The American colleagues moved not only the launch of the Dragon-2 ship in unmanned mode, but in general all the next launches of their ships to the ISS. For example, the launch of the Dragon cargo ship, scheduled for March 16, was postponed to mid-April. in unmanned mode, scheduled for March 28, moved to the first half of May, "- said the agency interlocutor.

My emphasis
DM-1 in "first half of March" as of Wednesday but "the first half of May" as of Thursday?
How much weight should we give this?
(Should it even be here in Updates?)

I think the reference of moving to May regards the Starliner capsule, not Dragon 2.

They are talking about the CRS-17 mission which has been delayed to NET mid-april and about Starliner which is now on the first half of May. Sometimes it's good to read things twice and carefully when it is translated by Google.

In the picture of the DM1 on the launch pad, it appears to me that there are no exhaust ports for the SuperDracos.

As I recall, the ports are in place, they are just sealed with the silvery film - for hydro-protection.
IIRC, the ablative coating is fairly susceptible to air moisture.

BTW, they do the same thing with the Dragon's ablative heat shield - it is covered with similarly looking silvery film.

The ports are there (but with launch covers), it is just hard to see in the light conditions of that picture. This picture shows them better:

Are those covers on the Super Dracos designed to blow up out if the engine starts or are they a "remove before flight" item?

kevinof · « **Reply #608 on:** 02/07/2019 04:06 pm »

If they are like the Dracos then it's on first fire. Now as these are the SuperDracos and only used for abort, they will stay in place which may even help with keeping water out on splashdown.

Wouldn't it burn off during re-entry?

They blow off. It will look like it does now at launch. The covers/seals look thicker then the regular Draco covers, but the SuperDracos have much more thrust so they will blow off easily.

hmm.. probably. Forgot about that.

Meant to say "blow out" rather than "blow up" in my earlier post. Slightly different meaning.

I'm not sure they would burn off during reentry as the openings are not where the heat shield is located. Hopefully won't be too much friction heating there.

I could see the plugs being made to stay in place unless an abort happens. Being that those engines are not used for landing anymore, they shouldn't fire at all during a nominal mission. If the plugs stay in place, they would also help to keep salt water out of the engines.

Post FRR presser on Friday.

Also confirms it's an Agency level FRR per Gerst's involvement.

https://www.nasa.gov/press-release/nasa-spacex-demo-1-briefings-events-and-broadcasts

Also shows they are rather confident to already set the presser up.

Is this the first time we've heard the launch time? I have to say I don't know if I'm going to be watching this live at 2:48am EST on a Saturday

That's the same hour of day that has been reported these last two weeks since they sticked with March 2nd, nothing new.

NASA, SpaceX Demo-1 Briefings, Events and Broadcasts

NASA and commercial crew provider SpaceX are targeting 2:48 a.m. EST Saturday, March 2, for the launch of the Demo-1 uncrewed flight test to the International Space Station. The uncrewed test flights will be the first time a commercially-built and operated American rocket and spacecraft designed for humans will launch to the space station.

Live coverage will begin on NASA Television and the agency’s website Friday, Feb. 22 with prelaunch events.

The SpaceX Crew Dragon spacecraft will launch on a Falcon 9 rocket from the historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 10 minutes after launch, Crew Dragon will reach its preliminary orbit. It is scheduled to dock to station Sunday, March 3 at 5:55 a.m. EST. The Crew Dragon spacecraft will carry about 400 pounds of crew supplies and equipment to the space station and return some critical research samples to Earth.

The spacecraft will spend about five days attached to the space station. Dragon will remain at the space station until March 8 when the spacecraft will return to Earth. About five hours after Dragon leaves the station, it will conduct its deorbit burn, which lasts up to 10 minutes. It takes about 30 minutes for Dragon to re-enter the Earth’s atmosphere and splash down in the Atlantic Ocean.

The deadline for media to apply for accreditation for this launch has passed, but more information about media accreditation is available by contacting [email protected].
