Moon joy [noun]
the feeling of intense happiness and excitement that only comes from a mission to the Moon
The Artemis II crew bring us endless Moon joy.
saw a post saying we are so emotionally invested in the artemis ii mission because it shows intelligent people working together to do difficult things. and honestly, that resonates. it feels like a reminder of what is still possible
We have shipped our 20kW satellite - Gravitas - to the launch site.
Given the supply chain to operate at this power regime doesn’t exist, we had to build 85% of the satellite in-house. This includes building our own large solar arrays, high power propulsion system, large batteries, large reaction wheels and much more.
This launch will represent the first time all of these systems are test on orbit together.
Internally at @K2SpaceCo, we’ve thought about a few levels of success for this mission - we expect mission success to fall somewhere along this spectrum:
- Tier 1 (Baseline mission success): Deploy solar arrays, establish comms, operate the satellite —> we’ve now got an operational 20kW satellite on orbit
- Tier 2: Power on the payloads, activate the 20kW propulsion system —> we’re completing payload missions and have fired the highest power hall thruster ever flown on orbit
- Tier 3: Orbit raise the satellite, test performance in high radiation environments (like 2,000km) —> we’ve collected massive amounts of data on the performance of the platform in very very difficult environments
More than anything, Gravitas represents the start of an iterative journey, where we will take the data we receive from this first satellite and incorporate it into the next wave of satellites launching next year.
We’re excited to start this journey, we’ll report back as we get more data.

At K2 Space, we're Building Bigger to deploy the largest satellites ever on orbit.
Over the next few weeks, we'll be highlighting some of the technical challenges behind our upcoming Gravitas mission, and the people leading the solutions.
To start the series, we sat down with our CTO, @neelkunjur, to talk about what it takes to build and fly a spacecraft of this size and power for the first time.
As Neel puts it, building at this scale is "an enormous engineering challenge… not only are there 50 new systems you have to invent, but the physics are extremely unforgiving."
From the gigantic solar arrays to the 20 kW Hall thruster, this mission puts the technologies K2 has developed into their operational environment. Moving from ground test to flight will give our team the data to advance our Mega Class satellite into its next stage.
As Neel says, “We believe our job doesn’t stop when we deliver hardware for integration. It ends when the hardware and software are operating reliably in space.”
