SpaceX and other space stuff

Meanwhile, SpaceX's filler music is always cool. In my imagination, I'm grooving in a space disco. :cool:

(I'm also quite a few years younger so that scenario doesn't look weird.) :roflmao:
I was thinking the same thing, I wouldn't typically go for "techno-synth-pop" but Starfish always nails it. Very upbeat, too, also not my usual cup'o'tea.

Standing by for satellite deployment.

Who, with their twitchy fingers, is doing the camera switching for this broadcast?? :roflmao:
Yeah, they seem to have a delay on the cameras, and keep switching away just as something's about to happen... ...anyway, they released just fine. :)

Falcon 9 launch scheduled for 16 Feb, Sunday, at 10:25am EST (1525 UTC). Flight 4 of Starlink satellites, total of 60 this flight. Satellites will be deployed around 174 miles (280km) high.

4th flight of the 1st stage booster, 3 previously flights in 2019. Barge landing of booster expected.

Launch was delayed from Saturday, bad weather forecast for recovery area. 90% GO for Sunday.
 
Well, we know the first stage missed the landing barge. Still haven't found out why yet.

Fairing half catches were tried for this flight using the recovery ships MS Tree and MS Chief. This is what's supposed to happen:


Not this flight, though. Each ship brought back a broken, damaged fairing half. Fairing quarters? lol:

Saw some pics of the parasail of one fairing ripped and fouled in the recovery net. Don't know if any of this happened on catch attempt or recovery from the water.

Anyway, thought this was interesting.

Just like landing the boosters - takes a while, practice makes perfect! ;)
 
Old news: The Starlink flight discussed above finally has a reason the 1st stage missed the barge. The winds the first stage felt were not as predicted. There's programming in the first stage that makes landing abort decisions if some parameter isn't correct. The booster itself decided to miss the barge because wind predictions weren't correct. Spacex has made improvements in predictions since this incident, according to Spacex engineer tweet.

N-n-n-new news: ISS re-supply mission launch from Cape Canaveral, Fl, at zero-dark-thirty EST this morning (3:50am EST) using the Dragon space capsule. I stayed in bed LOL. 1st stage returned to launch site.

Here's a video, rather long. I just skipped to the major events lol. Nice video footage for this one.

If you wanna skip, here's the time marks of the vid:
19:45 Launch
22:15 First stage seperation. Immediate turning around and starting of the first stage Boost Back Burn to point it west for return to land. Cool footage of the two exhaust plumes, 1st and 2nd stage, creating pretty chaos as they interact.
26:33 First stage start of Entry Burn. Needed to slow stage down before it enters thicker atmosphere at lower altitudes.
27:40 First stage Landing Burn and landing.
29:35 Dragon capsule separation from 2nd stage.
32:01 Dragon capsule solar panel deployment.


This is the last flight of the first version of the Dragon capsule. Will be using updated version from now on.

Also the 50th landing of a first stage booster! It was 11:30 PM here, but I didn't stay awake for it, either.
