well, what a fantastic re-entry & splashdown for #ArtemisII 🎉

gratz to everyone at #NASA (especially the #DSN & #TDRS folks 💕), #CSA, & #ESA 👏👏👏

#Artemis

Apr 7

the important #ArtemisII numbers from #NASA’s #DSN 🎉 👀

RANGE
412.00 thousand km

ROUND-TRIP LIGHT TIME
2.75 sec

🌏📡~~~~~~~~~~~~~~~~~~~~🛰️ 🌒

DSS-43 & DSS-34 are both communicating with #Artemis on S-band:

DSS-43 has downlink @ 3Mb/sec and -110 dBm

DSS-34 has downlink and uplink

(not shown: at the time this screenshot was taken DSS-34 had downlink @ 3Mb/sec and -110 dBm & it’s uplink was transmitting @ 0.2 kW

fantastic work by everyone out at #CDSCC and the rest of the DSN 👏👏👏

This is how NASA stays in touch with various missions in and out of the solar system...

it looks like DSS-43 & DSS-34 out at #CDSCC^ are setting up to communicate with #ArtemisII during their ##TLI burn @ 10:49 local time (AEDT)… 👀

ETA: it looks like the DSN will just be watching & waiting as #Orion has switched back to #TDRS for the TLI burn – I’m guessing DSN is pointed & tracking Orion on standby in case they’re needed (🤞 not)

#DSN on #ART2
#NASA
#Artemis

^ the #Canberra Deep Space Communication Complex

note: #DSN uses a “follow the sun” approach for operating antennas, so the antennas at #MDSCC in #Madrid are currently being operated by the ops team at #CDSCC in #Canberra since it’s day time here in #Aus & night time in Spain 🙃

normally there’s only a skeleton maintenance crew on site at the Deep Space Communication Complexes overnight but I expect there are some additional staff on site (or on call) just in case for such important mission support

https://eyes.nasa.gov/apps/dsn-now/dsn.html

you can see what’s happening on the #DSN Now website, part of #NASA’s #EyesOn visualisation tools

antennas showing “ART2” are currently in direct comms with #ArtemisII & antennas showing “DSN” are mostly^ tasked to #Artemis mission support but not currently communicating with the spacecraft

– antennas with “squiggly lines” going in both directions are both transmitting & receiving data (Tx & Rx)

– antennas with a squiggly line going in one direction is currently either transmitting or receiving data

– antennas with a sine wave line have carrier lock but aren’t transmitting or receiving (not shown)

– details about the comms for the selected antenna are shown in the panel at the bottom of the page

you can see in the attached pic that antennas DSS-54 & DSS-56 at #MDSCC (the Madrid Deep Space Communication Complex) are currently communicating with ArtemisII – 54 is both Tx & Rx on S-band & 56 is Rx on S-band and data rates look great

^ I say “mostly” ‘coz “DSN” usually means testing or maintaining – one or two antennas may be undergoing maintenance atm rather than supporting ArtemisII, I don’t have complete visibility of the antenna schedule 💁‍♀️

successful handover to #DSN, w00t! 🎉
