TYCHO will bring permanent communication to Moon's far side via TMA-0 communication relay satellite on Earth-Moon libration point EML-4... and it uses LASER!

Nice to see the Earth-Moon cycler orbits our lab recently discovered featured in @GarretsonPeter's overview of the cislunar space economy. Lots of interesting possibilities for transportation, surveillance, and infrastructure.
This is a fantastic video explaining orbital dynamics and the resulting economics, and security considerations of cislunar space. Well worth the 8.5 minutes to watch. youtu.be/kdpOdSMzXTA?is=By6z…

SpaceX will provide connectivity throughout the solar system and beyond
Michael Nicolls just just laid out SpaceX's ambition for connectivity that extends beyond Earth
“We will connect the Moon with a constellation, and then we will connect Mars”
"Our goal, again, is to extend consciousness beyond this planet, and we want to go and connect the Moon and Mars
But before that on Starlink, we're creating the technologies to connect the Moon with very high-bandwidth connectivity systems, very high-bandwidth lasers
And we will connect the Moon with a constellation, and then we will connect Mars, and we will form an interplanetary mesh of connectivity that is fundamentally driven by the same technologies we're working on with Starlink
To make this happen, SpaceX needs to keep improving safety in LEO so everyone can operate and scale safely”
Build safe, coordinated infrastructure in LEO first then extend connectivity and human presence to the Moon, Mars, and beyond

What if a spacecraft could cycle between Earth and Moon orbits, performing multiple circuits of each, naturally and indefinitely, with zero propulsion?
We’ve discovered a new class of stable, prograde, low-energy cycler orbits that do just that.
Why these orbits matter:
Ballistic → fuel-free
Stable → long-term ready
Near-chaotic → agile with low ΔV
Low-energy → access to Earth/Moon, Lagrange points, Sun–Earth L1/L2, even heliocentric space
At the AAS/AIAA Astrodynamics Specialist Conference in Boston next week, I’ll present on a new family of ballistic Earth-Moon cycler orbits that are stable, prograde, and mission agile—unlike any cyclers in the current literature.
The example below is shown in both the Earth-Moon rotating frame and inertial frame.

🌒 Can you build the infrastructure to deliver #communication and #navigation services in Lunar Orbit? Answer to the ITT before 26 May 👉 bit.ly/3LdAhlT
Under the #Moonlight Programme, @esa will act as an anchor customer while the services can be sold to other entities

Taken during the #Artemis I Moon flyby, the optical navigation camera aboard the @NASA_Orion spacecraft closely captured stunning pics of craters on the Moon. 🌕

Yesterday, @NASA_Orion manoeuvred its solar arrays and captured the Moon as seen here with a camera mounted on the end of the array. The #Artemis I spacecraft is now over halfway to the Moon.

Handover complete! The @NearSpaceNet has handed over #Artemis comms to @NASA's Deep Space Network!
The NSN successfully enabled communications for @NASA_Orion during launch and early ascent. Now, the DSN will support the spacecraft en route to and in orbit around the Moon.

We’re going back to the Moon and staying ! 🚀🌕
As we explore the moon further and establish a lunar economy, @EsaTelecoms will provide connectivity to lunar activities and exploration through our #Moonlight programme 🛰️ #Artemis #ForwardToTheMoon
LIFTOFF of #Artemis I on 16 November 2022 from @NASAKennedy, carrying the first @NASA_Orion spacecraft with its European Service Module #ForwardToTheMoon!

Bonjour Paris!
Don‘t forget, today is our #IAC2022 presentation „AUTO-TDS: Enabling #laser communication networks to auto detect incoming links, securing connection & auto-routing the data“ in B2.5 at 10:45.
Feel kindly invited to join us there.
#hydron #scylight #moonlight #edrs – at Vanves, France
During @IACParis2022, @esa‘s DG @AschbacherJosef said during the Heads of Agencies Plenary that there will be more news about #ESAmoonlight on Monday.

The #Artemis I mission will require both of @NASA's communications networks to work together to enable a seamless mission.
Different communications services will be needed as @NASA_Orion leaves Earth, orbits the Moon, and returns safely home.

Moon orbits can look wonky, depending where you watch from. This is a Halo Orbit, used this weekend by @RocketLab's CAPSTONE bit.ly/39VGiTZ.

How we choose to settle the Moon, now, will establish how we explore and settle everywhere beyond. Pivotal moment in time. Please help fund a research fellow - thanks!
This June & July, we will highlight our fellowship program through #fundafellow campaign! Your support enables our Fellows research to drive humanity's lunar future. Learn more: openlunar.org/fellow

MISSION UPDATE: After a successful first trajectory correction maneuver on July 7, the #CAPSTONE team is standing down from today's scheduled maneuver to perform additional analysis on the spacecraft and determine whether it is still needed at this time: go.nasa.gov/3ACAKJ7
