Artemis II Countdown: How to Track Friday’s High-Speed Splashdown

1. The “Final Leg” Tracker (Tonight: April 8)

The astronauts (Wiseman, Glover, Koch, and Hansen) are officially back under the influence of Earth’s gravity.

  • The Mission Status: Today, they completed their final exercise routines and began “stowing for entry”—securing all loose gear inside the Orion capsule to prepare for the bumpy ride through the atmosphere.
  • How to Track: Recommend the NASA AROW (Artemis Real-time Orbit Website). It shows the capsule’s exact distance from Earth in real-time. Tonight, they are roughly halfway between the Moon and Earth, traveling at over 2,000 mph.
  • The Visual: Have your readers find the Moon tonight. It’s a Waning Gibbous (about 68% illuminated). Tell them to look at the space just to the “left” (east) of the Moon—that is the path the crew just traveled.

2. Preparing for the “Fireball” Splashdown (Friday, April 10)

The splashdown is scheduled for Friday, April 10, at approximately 8:07 PM EDT (5:07 PM PDT).

  • The Location: The Pacific Ocean, just off the coast of San Diego, California.
  • The Reentry Phase: At 7:53 PM EDT on Friday, Orion will hit the “entry interface.” It will be traveling at 24,840 mph (about 32 times the speed of sound) and will heat up to 5,000°F.
  • The “Blackout”: For about five minutes during reentry, the plasma surrounding the capsule will block all radio signals. This is the most intense “seat-of-the-pants” moment for mission control.

3. The “Light Bucket” Mission for Tonight

Since you are a blogger, give your readers a “Mission Assignment” for tonight to get them ready for Friday’s finale:

  • Target: The Sea of Tranquility on the Moon.
  • The Goal: Photograph the landing site of Apollo 11.
  • The Context: “The Artemis crew just flew over this spot 48 hours ago to scout it for the upcoming Artemis III landing. Look at those craters tonight and realize that for the first time in 50 years, human eyes just looked at them from only 4,600 miles away.”

The “Home Stretch” Alert (Tonight, April 8): The crew has successfully exited the Moon’s gravity and is accelerating toward Earth.

  • Activity: Use the NASA AROW tracker to see the “Earthrise” from the capsule’s perspective.

The “Blackout” Alert (Friday, April 10 – 7:53 PM EDT): This is the most dramatic moment. For several minutes, a layer of ionized air (plasma) will surround the capsule as it hits the atmosphere at 24,840 mph, cutting off all communication with Houston.

The “Parachute” Alert (Friday, April 10 – 8:01 PM EDT): Watch for the deployment of the 11 massive parachutes that will slow the Orion from supersonic speeds to just 17 mph.

The “Splashdown” Alert (Friday, April 10 – 8:06 PM EDT): The final splash in the Pacific near San Diego.

Stan’s “Splashdown” Tip

“For readers on the West Coast, look toward the ocean around sunset on Friday. You might not see the capsule, but the sonic boom and the recovery ships (like the USS John P. Murtha) will be making history right off the shoreline!”

This Artemis II Mission Overview provides a great visual breakdown of the reentry and splashdown process to help you understand the “skip-entry” maneuver Orion will use on Friday.

This video is relevant because it explains the complex physics and timing of the Orion capsule’s return to Earth, which is exactly what your readers will be tracking over the next 48 hours.
