Oh go on then ;)

What did Artemis II look like from an RF Doppler perspective? 📡〰️🚀🌖 (thread)

In January, we were selected by NASA to support tracking of the Artemis II mission using our ground station infrastructure.

Artemis II talking to ISS - spaceships calling other spaceships!

As noted a couple weeks ago, stood to reason that Apple, despite their large ownership stake and satellite deal, would actually *like* Amazon taking over Globalstar... thoughts.spyglass.org/i/192991624/...

😬😬 “Reject idea of safe return” 😬😬

I'm struck by the number of modes of transit these astronauts will experience today.

1. Slicing through the Earth's atmosphere in a spaceship
2. An inflatable raft
3. A rope swing
4. Helicopter
5 Aircraft carrier
6. Airplane.
7. Van.

If you’ve been moved & inspired by Artemis, NASA needs your help. Literally during A2, the president proposed cutting NASA science 47%, canceling 54 missions, including many already in-flight. To help stop these cuts, check out @planetarysociety.bsky.social www.planetary.org/save-nasa-sc...

Welcome home folks, welcome home.

Last one on #artemis via some basic python scripts! Next, is the #ISS setup for @soph-astro.esa.int / @arissintl.bsky.social

Here's a reminder for Sophie Adenot fans - there are 2 contacts upcoming with France tomorrow.

First, Friville-Escarbotin is up with a direct contact. YT: www.youtube.com/@lyceeduvime...

90 minutes later it's La Norville's turn. www.youtube.com/@Universit%C...

During #Artemis II's Moon flyby there were around 40 minutes without contact back to Earth📶 🌍️

@esa.int 's Moonlight aims to fill this gap by deploying a constellation of communication and navigation satellites around the Moon to never lose connection when most needed 🌑

Top 3 (Ultrarough^TM) link outputs:

CANBERRA (DSN): windows=9, vis=62.1 %, mean margin=9.52 dB, min margin=4.58 dB

GOLDSTONE (DSN): windows=8, vis=24.7 %, mean margin=8.23 dB, min margin=4.76 dB

Enough playing for me on #artemis orbits & schedules.

(Ultrarough) vars here shows the orders of magnitude for a lunar link: tx-power-dbw=20, tx-gain-dbi=16, rx-gain-dbi=52, bitrate-bps=1024e3.

We're getting somewhere #artemis orbit. Needs more checks. Next: Comms!

Via ssd.jpl.nasa.gov/api/horizons... we can find #artemis mission & orbit files. We need this to convert to .bsp / .spk so we can then do some orbit propagation. Neat.

OK! Back from Easter, time to play with #artemis orbit & #python - on your marks, get set .. go! (doubt there's an IQ / SDR file online but one can hope)

Oh hi @matthewcosby.bsky.social 👍📡👍

Rgr 73 👍

External view showing part of Orion and the Earth.

Good: getting some external images from Orion.
Bad: the crew is troubleshooting the toilet.

Hey Scott- Where’s those bsps and excel files from? I’m wondering if we could map those stages to actual DSN passes.

Well that got you a follow 👍

ARISS voice repeater radio setup in the ISS Columbus module with Kenwood transceiver and cable connections, plus overlaid announcement of March 19 repeater activation and STEM contact with Sophie Adenot.

Just a few more hours until the cross band voice repeater comes back online following today's ISS spacewalk.

Also tomorrow, it's a STEM contact with California via a ground station in Italy - we call that a telebridge contact.
