Author Topic: SpaceX Falcon 9 : PAZ & Microsat 2a/2b : SLC-4E : Feb 22, 2018 : DISCUSSION  (Read 207690 times)

From the update thread, it looks like this is another launch that will have daylight on the rocket while it is still dark on the ground.  Considering what happened the last time this condition was present, I wonder how many traffic accidents there will be and how many people try to sue SpaceX for crashing into someone (or being crashed into) while drivers are paying more attention to the rocket plume than the car in front of them.
How many people are likely to be driving around at 6:20am on a Sunday morning?
Following the space program since before Apollo 8.

What's the launch weather forecast for Sunday?

From the 30th SW Facebook page:

L-2 Day Planning Forecast

Western Range Operation Forecast
Issued: 16 Feb 18 / 0615L (1415Z)
Valid: 18 Feb 18 / 0616L (1416Z)
Vehicle/Payload: Falcon 9/Paz Demosat
Location: VAFB SLC-4

T-0 Forecast: The ridge of high pressure gradually weakens which will allow a frontal system to move in from the north. This will result in onshore flow and a return of marine layer clouds. Surface winds will be out of the northwest through north from 330-360 at 10-15 knots for T-0 while temperatures will be between 48-53F. As the jet stream approaches, Upper Level winds will be northwesterly from 290 at 65 knots between 22,000 and 25,000 feet. The overall POV will be 10% with ground winds being the only area of concern.

Scrub Forecast: With the cold frontal passage late Sunday, high pressure builds into the Great Basin. There will be some residual low level clouds, but otherwise, fair conditions will prevail. A secondary trough of low pressure will enhance the pressure gradient so surface winds will be elevated from 350-020 at 12-18 knots for T-0 while temperatures will range between 46-51F. Upper level winds be out of the northwest from 300 at 45 knots between 29,000 and 32,000 feet. The overall forecast is Favorable with ground winds being the only area of concern.

Significant Clouds:
Stratus
Cirrus
Coverage
8/8 ths
2/8 ths
Bases
400 ft
25,000 ft
Tops
1,200 ft
26,000 ft
Visibility: 2 Miles
Weather: Fog
Wind: 330 - 360 at 10 - 15 knots
Temperature: 48 - 53° F
Overall probability of violating weather constraints: 10%
Area of concern: Ground Winds
Overall probability of violating weather constraints for Scrub Day: Favorable
Area of concern: Ground Winds
Next Forecast Issuance: 0700L / 17 Feb 18

I wish someone would correct the timestamp on the webcast for the launch (http://www.spacex.com/webcast)
It is still showing webcast coverage for the 17th, starting in about 7 hours from now.

The website itself is correctly updated though.

Team at Vandenberg is taking additional time to perform final checkouts of upgraded fairing. Payload and vehicle remain healthy. Due to mission requirements, now targeting February 21 launch of PAZ.

Upgraded fairing?

Well this leads us to believe no one wanted upgraded fairing on first flight so they must told these guys, your getting sweet deal on this launch that we going to try some new things out....

Along with the reused S1 discount this specific launch must be a really good price (If Hidsesat got a discount for testing fairing 2.0)

Would this upgraded fairing be designed with recovery and reuse in mind from the start? And might this be the first one caught by Mr. Steven?
I'll even excitedly look forward to "flags and footprints" and suborbital missions. Just fly...somewhere.

"Fairing upgrade" in this instance may be in relation to changes after the issue was encountered during preparation for the Zuma launch or some added capability/hardware for recovery efforts.
Shouldn't reality posts be in "Advanced concepts"?  --Nomadd

Or referring to Fairing v2.0 first flight.

Well Elon did say "Fairing 2 flying soon".

However normally "soon" in Elon time means at least a couple of months, not within a week.

Yeah because the first FH flight is still 6 months away, isn’t it? ::)

If the ride share satellites are going to communicate, they will need FCC licenses. They can be referred to as a couple, a few or a whole passle of satellites, we will know them but their licenses.

Matthew

Of course, but there's no reason why anyone would know or be able to tell them from AdamSats.  The only reason we know about the MicroSats is because the experimental license for them was applied for by SpaceX [which was a term/applicant being searched for already on the FCC search page].  But for 3rd party payloads, SpaceX wouldn't be the applicant.  In fact, the operator might not be applying at all (neither for an experimental license nor an STA) if they are making use of an amateur radio operator license (requires notification only).  Conversely, they could also apply as if it was a full sized satellite under the FCC's Part 25 rules.  In which case it would be through the International Bureau instead of the OET (Office of Engineering and Technology; an entirely different division of the FCC), and the search page that most normally use to stalk SpaceX filings wouldn't even return those results whether SpaceX was named or not, etc.  All of which is just to say that trying to determine whether there are additional rideshare sats on board based on a presumption of knowledge of FCC filings/licenses is a mistake.


FCC's GUIDANCE ON OBTAINING LICENSES FOR SMALL SATELLITES- https://apps.fcc.gov/edocs_public/attachmatch/DA-13-445A1.pdf

As an example of this, I just randomly found one of the payloads for SSO-A.  I search the FCC experimental permits for companies with Space in the name which usually returns 90+% SpaceX results.  I happened to get one for SpaceQuest today and when I opened it to see who they were it turned out to be an application for a 3U cubesat launching on SSO-A.  If I actually searched the experimental permits for SpaceX (or the various other ways they put their name) I never would have known about that cubesat.

In my eyes, it's either of those. I really want Fairing 2.0, but I think it might just have some fixes or extra hardware on there (Maybe improved parachutes, better GPS/tracking, the list goes on...).

If this is the case, I wonder why they did not put the new fairing on FH demo?

Latest spy shots of Mr. Steven suggest a catch try is imminent, she has a net now, not just arms.

According to today's photos is high speed fairing boat Mr.Steven ready with net attached for recovery attempt of upgraded fairing.
