Live Science Today: Artemis II readies for rollout as auroras paint skies

Mar 22, 2026 | Space

**NASA’s Artemis II mission is revving up for launch, with the massive moon rocket scheduled for a return to the launch pad today. Meanwhile, the four-person crew is beginning their essential quarantine period as the countdown to an April 1 liftoff intensifies.**

Here are a few options for paraphrasing the text, maintaining a journalistic tone:

**Option 1 (Focus on the delay and reason):**

> NASA is preparing for a second launch attempt of its colossal Space Launch System (SLS) rocket, complete with the Orion spacecraft. The initial rollout on January 17th was followed by a series of setbacks, including two “wet dress rehearsals” and significant leaks. These issues prompted the agency to return the massive vehicle to the Vehicle Assembly Building for necessary repairs.

**Option 2 (More concise, emphasizing the repeated effort):**

> The gargantuan Space Launch System (SLS) rocket, topped by the Orion capsule, is set for its second deployment, following an initial rollout on January 17th. After encountering two “wet dress rehearsals” and experiencing two leaks, NASA opted to return the rocket to the Vehicle Assembly Building for repairs.

**Option 3 (Slightly more active voice):**

> Following an initial deployment on January 17th, NASA is again rolling out the immense Space Launch System (SLS) rocket and its accompanying Orion capsule. The space agency made the decision to return the rocket to the Vehicle Assembly Building for repairs after two “wet dress rehearsals” and two documented leaks presented challenges.

**Key changes made in these paraphrases:**

* **Synonyms:** “enormous” replaced with “colossal,” “gargantuan,” “immense.” “perched atop it” replaced with “topped by,” “complete with,” “accompanying.” “wheel back” replaced with “return.”
* **Sentence structure:** Varied the order of clauses and rephrased for a smoother flow.
* **Word choice:** Used more active verbs and descriptive language where appropriate (“setbacks,” “significant leaks,” “documented leaks”).
* **Clarity:** Ensured the reasons for the return to the VAB were clearly stated.
* **Journalistic Tone:** Maintained an objective and informative style.

This isn’t the first instance of an Artemis rocket requiring a return to the hangar. The Artemis I Space Launch System (SLS) rocket, for example, was brought back to the Vehicle Assembly Building on multiple occasions in 2022. Despite these setbacks, it ultimately launched and successfully completed its uncrewed test mission around the moon later that year. The accumulation of these delays has prompted NASA to implement a significant restructuring of the Artemis program. The agency is now setting a target for yearly launches and is considering reducing its reliance on SpaceX and Boeing for mission planning. Furthermore, NASA’s revised objectives include achieving two lunar landings by 2028.

Before the Artemis II mission can officially blast off, NASA will perform a final “wet dress rehearsal” and a comprehensive flight readiness review once the spacecraft is situated on the launchpad. Following these crucial steps, the agency will then determine and announce the optimal launch window.

The northern lights could be visible in the skies above 20 U.S. states near the Canadian border this week, after the National Oceanic and Atmospheric Administration (NOAA) issued a warning that two coronal mass ejections (CMEs) are due to strike Earth.

CMEs are plasma bursts ejected by the sun. If they clash with Earth’s magnetic field they can trigger geomagnetic storms, disrupting satellites and communication systems, and causing auroras.

Thermospheric lightshows have been incredibly common this month, thanks to a hyperactive sun and Earth’s side-on position relative to the sun during the spring equinox. Both phenomena have made March 2026 the best month for northern lights in nearly a decade.

Emperor cichlids, which dwell in east Africa’s Lake Tanganyika, don’t take kindly to being stared at — being more likely to attack human divers who gaze at them.

Interestingly, the fish also responded with equal aggression when divers looked at their eggs or hatched fry. This suggests they share the ability to infer intent from a gaze with primates and some birds.
