Have you noticed (at 26:29 of the hosted webcast) a couple of...objects passing zipping by...?

What do you think they are?

 

[Thunder Chicken]

Did you see or hear it Thunder Chicken?

No, darn it. I was probably on the way back to the visitor's center on the bus. I just got off my ship this morning. So close

 

[Messierhunter]

Wrong link.

Arg, thanks, fixed it.

It may be because English isn't my native language, but I think this guy needs some KSP experience. (I suspect Orbiter would be a fair few bridges too far)

What are the qualifications required to present a show like this?

Well done, MessierHunter!

I'm going to wager ice or foam insulation coming off the engine(s) and being blown past the rocket as it enters the atmosphere.

ISO standard 19794-5 compatible face. :lol: Maybe sufficiently capable of English language.

In other news, the launch of the Red Dragon mission by the Falcon Heavy has been pushed back to 2020 according to the press conference on Friday. Looks like there are still issues with the Falcon Heavy.

What did he say that was inaccurate?

 

[C3PO]

What did he say that was inaccurate?

Height adjustment burns aren't performed vertically ("away from the center of the Earth").

 

[Unstung]

Height adjustment burns aren't performed vertically ("away from the center of the Earth").

Technically, he did not specify which direction the burns were in but how the spacecraft moves with respect to Earth. Then he called the phases burns.

The launch was at 6:30 AM their time, so it's understandable if the presenters were tired and made mistakes.

:huh:

If you are tired that early in the morning, you should go to bed earlier. Yes, that is a very boring way of life, but my experience shows, that it is better to be awake when you are doing your work.

Well, Musk is rumored to overwork his employees. So who knows how late they were working the previous night.

 

[Urwumpe]

Well, Musk is rumored to overwork his employees. So who knows how late they were working the previous night.

Not my problem. Really. It is the problem of Musk then, if his employees are not doing a proper job, because he is not properly employing them. Maybe he can do this in the USA legally. In Germany he could quickly get sued for this. (We have laws regulating how much overwork is allowed and when our employer has to stop it. Its rather employer friendly, but gives us more rights there than in many other places in the free world...)

Maybe it's just me, but I got the impression that he was using words like "coelliptic" and "phasing" without understanding the basics of rendezvous operation. I can understand if a TV presenter makes this kind of mistake, but if you're working for a rocket manufacturer you should try harder IMHO.

 

[movieman]

Looks like there are still issues with the Falcon Heavy.

Um, yeah. Like having blown up the pad that was supposed to be launching paying payloads while they tested Falcon Heavy from 39A.

Until that's fixed, they're not going to be able to find much space in their schedule for launches that don't produce any income.

 

[DaveS]

The plan is to only do standard F9 launches from 39A until SLC-40 is back up and running again. Then they'll begin the preps for the first FH launch from 39A

Breaking news:

Spx 10 Dragon grapple aborted. Possible cause due to wrong ISS state vector value that is inputed into the relative GPS onboard Dragon's computer that determines the distance between Dragon and the ISS. Abort along R-bar. Dragon 1200 meters below ISS at the time of abort. 3.25a.m. ET. Everything is fine and the abort is triggered by Dragon's onboard computer.

Dragon to conduct raise track maneuver to enter raise track trajectory. Next grapple time is Thursday morning. Grapple time still TBD.

Currently the Control team at Houston is working with Spacex in Hawthorne,CA to replan the rendezvous. The team onboard the ISS is stowing the camera for the rendezvous today, since it is no longer needed now.

Updates:

The new burn plan will be published later today.

6a.m. eastern is the new grapple time tomorrow. Live coverage on NASA TV is expected to occur 2 hours earlier than the grapple time. Installation coverage begins 2 hours after grapple at 8a.m. eastern Thursday.

Spacex engineers are confident that the issue will not cause any problems to the rerendezvous on Thursday. Meanwhile the Progress 66 craft is fine with a 2-day rendezvous.

And here is the video on F9 2nd stage deorbit burn that people in Iran and Iraq saw and thought that it was a UFO.

Having sent the Dragon on its way, the Falcon 9 second stage was set for a very brief re-start of its engine for a retrograde deorbit maneuver, placing it on a sub-orbital arc intercepting the dense atmosphere over the Indian Ocean, south west of Australia. After crossing the Atlantic, the second stage passed over the English Channel, flew north of Paris and traversed Europe in just six minutes. The 12.6-meter long rocket stage then passed over Lebanon and Syria, heading to the south east over Saudi Arabia still bathed in sunlight before entering orbital night over the Arabian Sea east of Somalia.

Visibility of the rocket stage extended as far north as the Caspian Sea with favorable nighttime viewing for much of Iraq, Kuwait, Iran and the United Arab Emirates. Various videos of the event show the the Falcon 9 second stage as a fuzzy object due to gas around the vehicle from its cold gas thrusters and engine chilldown sequence that had been underway by that time. At one point, the object can be seen ejecting a plume of gas toward its direction of travel, representing the start of the vehicle’s retrograde deorbit maneuver.

And an off-topic news. Does anyone know this?

In 2016, debris from a second stage that had been left in orbit after a GTO launch rained down over Indonesia, causing damage to property on two small islands, illustrating the importance of safely removing rocket stages from orbit whenever possible.
