I don't think any of my photos are all that great, but I'm nonetheless happy to contribute them.

NASA Social got to be at section J of the NASA Causeway:

The fact that you photographed *everything* is fantastic just by itself, Lupi.  A lot of views of things we don't normally get to see.  And there are some great shots in there as well.

That is true! Not everyone gets to have their bus stranded inside Complex 39b!

There are two stories I'm gonna smile about for ages after.
The bus getting stuck on pad 39b, and Tory Bruno's spontaneous visit causing my friend (WaywardPlane on twitter) to freak out.
The launch was just the cherry on top, really.
I asked the last question on the NASA TV Briefing (the one relating to Junocam), and so much great stuff happened. It was really a wonderful time.

Even if i spent more time paying attention to the crawlerway rocks than the crawler itself.
(In my defense, I've seen the crawler a lot. It was cool seeing what it did to the rocks. It completely shatters them sometimes! One shard was even so jagged it drew blood while i was holding it!)

Wouldn't periodic dropouts suggest a tumbling action while a longer almost sustained dropout suggest off course???
Guess we will have to wait for NASA to give us an update.


or that the receiving station was listening through the exhaust plume...

Periodic dropouts CAN suggest tumbling, but in this case, don't. The TM we were getting between dropouts showed the SV was stable. The problem, in all likelihood, lies with the ground stations assigned to acquire the SV and retransmit that data to us. As it is, we'll probably have to wait for the recorded data to make its way to our TM lab.

The plume effects are allowed for when the link budget is calculated pre-launch. It doesn't last very long, and the dropouts - or complete lack of data for some long stretches - can't be blamed on that, entirely.

... an unbelievable 430,000 mph, setting a new record for the fastest man-made object in history. That is 120 m per sec!
I thought 120m/s sounded a bit slow- it should read 120 miles per second- which equates to 190,000 m/s!

Great tracking footage at 3:00 into the video (you can see the center core throttling down at 3:10) as well as a nice shot of booster jettison at 6:30:

Drop the adjective "wonderful" and you'll capture my feelings about this "monster"! This is my fourth mission of the year as prime NASA Electrical, and this "monster" is putting the finishing touches on wearing me down.

And I've still got Pegasus/ICON to finish off! I'm so glad I'll have all of next year to rest up!


Thinking of Jim, have you been working this mission?


Worked yesterday

Hey Jim and Kim,

out of interest, what did you do for this mission specifically? Its always very interesting to hear peoples stories about their hands-on work, would be interested to know some details on what you did. Anyone else here worked that mission? Would be interested in your stories as well! :)

I served as NASA primary electrical systems engineer. That means I monitored electrical assembly of the Delta stages at the factory. That includes cable harness fabrication, test and installation;as well as the electrical/electronic components that make up the Flight Termination System, the GPS Tracking System and the Ordnance Control System. Once at the launch site, I participated in vehicle checkout and integrated testing down to T-0. After launch, I have to do an in-depth review of the performance of my systems to verify that they performed correctly in flight.

I was also responsible for tracking the installation and test of electrical systems and harnesses installed on the third stage.

We also have a NASA Avionics engineer, Flight Controls engineer, and Instrumentation engineer that make up the rest of the Electrical/Avionics team assigned to any particular mission. In the case of PSP, we also had a third stage avionics/flight controls team assigned specifically to that stage.

Your angle was about the same as mine, where did you end up? I was at like... the furthest West part of the NASA Causeway.

I like the brush in the foreground on yours, it really frames it well!

Sierra Nevada Corporation Provides Hardware for Mission to the Sun

NASA’s Parker Solar Probe Spacecraft Begins Record-Breaking Journey


SPARKS, Nev., August 09, 2018 –

As NASA’s Parker Solar Probe spacecraft begins its historic journey toward the sun, it is equipped with components supplied by Sierra Nevada Corporation (SNC) that will perform mission-critical functions. The components were provided from both SNC’s Louisville, Colorado and Durham, North Carolina production facilities to the Johns Hopkins University Applied Physics Laboratory for the spacecraft.

“This mission is pushing the boundaries of spacecraft engineering to deliver much needed answers,” said Matt Johnson, vice president of programs for SNC’s Space Systems business area. “Space weather is causing tangible negative effects on satellites today, and we’re proud to be part of a mission that will help us understand the origin.”

The Parker Solar Probe will travel seven times closer to the sun than any previous mission. The mission aims to help scientists better understand solar wind, flares and energy particles, which creates ‘space weather’ throughout the solar system. Space weather can have negative impacts on satellites, harm humans in space and affect power systems and communications on Earth.  Launched August 12 from Cape Canaveral Air Force Station, Parker Solar Probe will travel up to 430,000 mph and its heat shield will reach temperatures of 2,500°F.

SNC Parts Provided

  *   Water Coolant Pump Motors:

  *   Circulate a gallon of water through tubes, effectively cooling the solar arrays

  *   Passive thermal louvers:

  *   Radiate excess heat without drawing power away from critical systems

  *   Solar Array Drive Actuators

  *   Tuck and deploy solar arrays around the 4.5-inch composite heat shield

  *   Antenna Gimbal Actuator

  *   Move and point the communications antenna back to Earth with extreme precision

  *   Electronic control unit

  *   Provides smooth control for the solar array drive and antenna gimbal actuators

Parker Solar Probe flew over Hiil sphere 0.01 AU 2018-Aug-13 17:31,
probe speed
Earth 12.35 km / s
Sun 17.26 km / s

ellipse parameters
Aphelium 1.009AU
Perihelium 0.205 AU

I note that the planned 1st perihelium after gravity braking at Venus should be 0.166 AU
The Helios probe was the nearest 0.29032 AU

Just for fun...

Way back in 1965, International Rescue (Thunderbirds) saved Sun Probe, a manned Parker Solar Probe like mission to retrieve matter from a solar prominence, just before it plunged into the sun due to failed retros.

Reference: http://thunderbirds.wikia.com/wiki/Sun_Probe

Photos (fair use claimed):
1) Sun Probe prior to launch at Cape Canaveral
2) Sun Probe en route to the sun
3) The probe is fired

Those were the days my friends...

Rocket Cam footage from the core stage through core shutdown and separation. You can really see the particles of the ablative engines sparkling away in the dark and the side booster gets lit up really nicely after sep.
