Follow Orion Creatively During NASA’s Artemis I Mission

Trajectory data from the Orion spacecraft’s first mission around the Moon will be available to the public through NASA’s Artemis Real-time Orbit Website, also known as AROW. AROW, available on NASA’s website and on the @NASA_Orion Twitter account, allows almost anyone with internet access to track Orion’s flight as it happens.

Orion will travel to the Moon and 40,000 miles beyond on Artemis I, its first integrated flight test with the Space Launch System (SLS) rocket. Users can download trajectory data from the flight, called an ephemeris, from the AROW web page.

The ephemeris data can be used to track Orion with your own spaceflight software application or telescope. It can also be used to create a physics model, animation, visualization, tracking application, or other conceivable projects.

This data is generated by the Flight Dynamics Operations (FDO) group in the Mission Control Center at NASA’s Johnson Space Center in Houston. FDO is responsible for trajectory operations of Orion, keeping track of where the spacecraft is and where it is going to be. FDO uses tracking data from the Deep Space Network and predictive models to constantly update Orion’s predicted trajectory, so the Artemis flight control team has the best trajectory estimate possible. An accurate trajectory is essential for achieving mission objectives, maintaining communications links, lighting, adjusting the trajectory, and more.

Links at the bottom of the AROW web article will have the most current posted ephemeris. The ephemeris is in the Consultive Committee for Space Data Systems (CCSDS) Orbital Ephemeris Message (OEM) standard — a text file containing a header, metadata, explanatory information, and ephemeris data, available in the .txt file format.

After the OEM header, Orion state vectors — data describing exactly where Orion is located in space, and how it is moving — in the Mean of J2000 (J2K) reference frame are listed at four-minute intervals until entry interface at the end of mission.  During trajectory maneuvers, the state vectors are reported in two-second intervals. Each state vector lists the time in Coordinated Universal Time (UTC); position X, Y, and Z in km; and velocity X, Y, and Z in km/s.

OEMs will be publicly available after Orion separates from the SLS rocket’s interim cryogenic propulsion stage that will give the spacecraft the big in-space push needed to fly beyond the Moon. Entry data will also be available for Orion’s return to Earth.

I'm not saying that Roy's romantic relationships didn't work bc he mistook platonic and/or sexual attraction for romantic attraction and he is much better when he is not in a romance bc it's when he isn't forcing himself into amatonormativity (since he is probably aromantic and hasn't figured it out yet) but that is exactly what I'm saying

I'm at my mom's for a bit and typically don't answer her home phone, however the same number called twice in a row so I was concerned and picked it up. I immediately heard a call center and 'is this (moms name)? So I said no it is not thank you very much and hung up.

She called back! Again! So I answered 'hi, what do you need'' and she responded with 'im just trying to figure out if this number is for (moms name). So I said sorry, i't sounded like a spam call but yes this is her number. This is her daughter, she is not available, what do you need.' I want to be clear that my tone was not annoyed but rather brusque and matter of fact. Like someone repeating details to ensure you've gotten them right.

The lady legit went 'oh my goodness, so rude' and hung up on me and I'm hilariously bothered by this when I should just be laughing?

#tumblr as time capsule #in which i even want the telemarketer to like me after the fact #who calls three times in arow #is this a first

this is not just me complaining bc its one of my chores but i truly donot think the kitchen needs 2 be mopped twice aweek

#and swept 3 times a week 3 days in arow #likee. if were gonna sweep that often it should be spaced out more.. we have the weekend off for chores but i feel like itd make sense for #it to be monday wednesday friday IF it has 2 be a three times a week chore #but tbh id have it be like. at MOST a once a week chore and tbh irl probably more of a 2 weeks-monthly chore #mopping DEFINITELY just monthly unless theres a spill... #idk if thats like. insane and i fully admit my likee. knowledge of how often things should be cleaned is not very good bc my moms a hoarder #and gets very very very stressed out by cleaning stuff so our houses have always been Insanely messy. not that im like blaming my mom ik #its hard for her. it just also means that i dont know likee. how often mopping should be done bc that was like.. maybe once a year. but #in practice i can count on one hands the emt of times our house was mopped #even if there was a spill itd usually just be a towel and move on thang #and to be clear ik like thats not great ik that. ik our houses were always pretty grody #i just dont think mopping 2 times a week is necessary. basically.. #the mopping is umm monday wednesday i think. which is just weird 2 me it should be evenly spaced throughout th week right... #BUT AGAIN i think it should just be a every 2 weeks-once a month thang #unless it gets dirty.. but what do i nose #genuinely. if im like wrong here sry i genuinely dont know etc.

Portrait_of_the_artist_as_a_young_man.jpg Hi, my name’s Martin and I will be your waiter for today! I started hating your guts the moment you entered the restaurant. If you’ve seated yourself at a dirty table that hasn’t been cleaned yet I will be imagining disemboweling you in vivid detail. Will you be drinking anything? I will be making fun of you and your stupid order with my coworkers the moment you’re out of earshot and I will be spilling your drink at least once during our interaction. The floor around you will be sticky for the rest of your meal, because in order to mop up I’d have to get on my knees like your supplicant with a rag and I’m not paid enough to do that. Would you like to make that a combo? I’ve already forgotten your face, so no use coming up to me in order to make an additional order. Sit and wait until I come to you. If I do. Enjoy your meal and please leave a tip if you wish! :)

#im the nightmare waiter your therapist promises doesnt exist #im obviously taking the piss #but make a man pull an 11 hour shift at the same restaurant five times in arow #and his pleasant customer oriented demeanor vanishes #me #digital art #im coping

How to Use Data From NASA’s AROW Tweets

Follow NASA’s Orion spacecraft on its first mission around the Moon with the Artemis Real-time Orbit Website (AROW). AROW visualizes data collected by sensors on Orion and provides periodic real-time data during NASA’s Artemis I mission. AROW is available on NASA’s website and on the @NASA_Orion Twitter account.

AROW will periodically tweet a set of Orion’s state vectors — data that describes precisely where Orion is located in space and how it moves — from Orion’s official twitter account once Orion is flying on its own. 

You can use the information shared in AROW Twitter updates, explained below, to create a physics model, animation, visualization, tracking app, or anything imaginable. Here are some ideas for getting started:

Use the fundamental statistics to track or graph Orion’s distance from Earth or the Moon; its total distance traveled, closest lunar approach, farthest distance from Earth, etc.     

Use the applied statistics to track or graph Orion’s acceleration due to gravity at a given time, using the position of Earth and Moon or comparing Orion's trajectory to the Apollo missions.

Create an animation or visualization of the mission to scale — maybe a time-lapsed view from inside the crew module looking out the window.  

Based on data, recreate the mission in a space flight simulation video game platform with realistic orbits and maneuvers.

The data shared in AROW tweets are Orion’s state vectors, defined within the Earth-centered inertial coordinate frame J2000.

The P (position) coordinates provided represent Orion’s location on three planes:

Position (miles):

x=-237851, y=8725, z=23584

The x–y plane matches the equatorial plane of Earth.

The x-axis is permanently fixed in a direction relative to the celestial sphere, which does not rotate as Earth does.

The z-axis lies at a 90° angle to the equatorial plane and extends through the North Pole.

The y-axis is found by rotating the x-axis by 90° east around the z-axis.

To find a value for Orion’s distance from Earth, the Pythagorean theorem () can be used.

The three V (velocity) vectors represent Orion’s rate of change, corresponding with the position coordinates above:

Velocity (miles/hour):

x=1000, y=1251, z=300

As with position, the Pythagorean theorem can be used to find a value for Orion’s speed.

Also provided are O (orientation) vectors that describe the way Orion is pointing:

Orientation:

x=360.0°, y=0.0°, z=177.2°

Orion’s orientation is represented as three rotations measured in degrees around each of the axes laid out above.

Through Artemis missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
