Moon Base 13, The Moon: NASA Is In Kinga Forrester's Pocket

Good science reporting:

Using gravitational wave data to calculate pi. It’s a bit of a joke “project” but it is funny that the paper actually got reported on.

Sath, how long until you know if the paper gets accepted/rejected?

No idea. Everything is fucked in pandemic mode. Could be weeks could be months. Many months if we need to make revisions and re-submit.

Damn. Well, I look forward to the findings. Outside of auroras, have you seen any evidence of X-Ray or UV emissions from Uranus or Neptune?

Neither of those planets will have the same mechanism for independent generation that Jupiter does. Saturn likely does and we will be attempting to get a proposal in for Saturn next year. If Neptune or Uranus are visible in UV/X-ray (they are I'm p. sure) it is just reflections of solar X-rays.

We got like 6 x-ray photons from Pluto during like a 160,000 second observation or something many many years ago lol.

Just a friendly reminder that the first crewed SpaceX launch is still a go for tomorrow at 4:33p EDT. Weather is somewhat favorable.

[Cail]

Wish I could be in the area to see it live...TV will have to suffice. Pretty excited

~90min to launch. Streams are live if you're interested in the pre-flight bits.

[Xno Kappa]

I thought the launch was at 4:33 EST?

[TsingTao]

Bah, you're right and I'm dumb. Time zones, how do they work?

Still 2h then. Fun watching them talk about the instrumentation (happening now) and all the other stuff to fill time.

[Boyiee]

Yeah it's at 4:33 p.m. Eastern but there is a 60% chance it is scrubbed due to weather.

[Meresgi]

The suits are pretty sexy I gotta say.

[Xno Kappa]

Yeah they look like something out of a video game lol.

[TsingTao]

Trump buzzing the launch tower in AF1. And yeah, the suits are pretty cool.

Was thinking Mass Effect haha

The hatch through which NASA’s SpaceX Demo-2 crew members entered the Crew Dragon spacecraft has been closed and a leak check is complete.

Launch of the SpaceX Falcon 9 rocket and Crew Dragon spacecraft carrying NASA astronauts Robert Behnken and Douglas Hurley remains scheduled for 4:33 p.m. EDT from Kennedy Space Center’s Launch Complex 39A. Teams continue to monitor weather conditions throughout the area.

With about an hour and 15 minutes remaining until today’s 4:33 p.m. EDT launch time, the countdown is proceeding according to schedule. NASA’s SpaceX Demo-2 crew members, Robert Behnken and Douglas Hurley, are buckled into their seats inside the SpaceX Crew Dragon spacecraft, and its side hatch has been closed and checked for leaks. Teams continue to monitor weather conditions.

Here’s a look at some of the major milestones still to come. (Times are shown in “L-time” – minutes and seconds prior to launch time.)

-45:00 SpaceX Launch Director verifies “go” for propellant load
-42:00 Crew access arm retracts
-37:00 Dragon launch escape system is armed
-35:00 RP-1 (rocket grade kerosene) loading begins
-35:00 1st stage LOX (liquid oxygen) loading begins
-16:00 2nd stage LOX loading begins
-07:00 Falcon 9 begins engine chill prior to launch
-05:00 Dragon transitions to internal power
-01:00 Command flight computer to begin final prelaunch checks
-01:00 Propellant tank pressurization to flight pressure begins
-00:45 SpaceX Launch Director verifies “go” for launch
-00:03 Engine controller commands engine ignition sequence to start
-00:00 Falcon 9 liftoff

The Demo-2 mission will serve as an end-to-end flight test to validate the SpaceX crew transportation system, from launch to docking to splashdown. It is the final flight test for the system to be certified for regular crew flights to the station as part of NASA’s Commercial Crew Program.
