Sometimes following the water can lead to surprising places💧 A new study of data from Perseverance reveals that rocks in Jezero Crater were shaped by a complex sequence of ancient lakes, groundwater systems, and hydrothermal fluids. 1/2

Next week, NASA is slated to announce the next steps towards actualizing its vision for a Moon Base. Last week, Spaceflight Now Reporter @w_robinsonsmith spoke with Moon Base Program Executive Carlos García-Galán about what the public can expect to learn on June 30.

Big week for Artemis III 🚀 Just before NASA introduced the Artemis III crew, the SLS solid rocket booster segments arrived in Florida after a six-day rail journey from Utah. Later this year, teams will begin stacking the boosters that create 75% of the thrust needed at launch.

Well, well, look who's back! After several months of being hidden in the glare of the Sun, Mars is once again visible in the sky. But only for early risers – the planet appears as a small, reddish "star" low on the eastern horizon just before sunrise.

In an update from NASA this morning, the agency outlines the following for Artemis 3: • The SLS rocket will use a spacer, not the ICPS upper stage • The mission will be LEO only; no high Earth orbit • Astronauts "could potentially enter at least one lander test article" • Artemis 3 will be longer in duration than 9 days • Upgraded heat shield demonstration Remaining unknowns include: • Launch date/window • Timeline for naming astronauts • Precise orbit (altitude/inclination) • Exact mission duration • What science will be onboard • Whether Artemis 3 will include AxEMU spacesuit-lander interface demo nasa.gov/missions/artemis/ar…

NASA has given approval to begin implementing its project to support @ESA's Rosalind Franklin mission. Scheduled to launch in 2028, this Mars rover will be the first to search for signs of past or present life under the Red Planet’s surface. go.nasa.gov/4vAIeX1

My favorite image so far. Orion, built by human hands in just a few years, set against a moment billions of years in the making.
The eclipse from Orion. On April 6, external cameras attached to the Orion spacecraft's solar array wings captured the Moon backlit by the Sun during a solar eclipse.

The Orion spacecraft successfully separated from the upper stage of the rocket, and the "proximity operations" test is underway. The Artemis II astronauts are manually piloting Orion similarly to how they would if they were docking with another spacecraft.

In recent days, NASA officials including Administrator Jared Isaacman has discussed a new effort, yet to be formally announced, that would call for sending robotic landers to the moon as frequently as monthly, potentially to support development of a future lunar base. bit.ly/4bFWg0E

We have just proven that we can deflect asteroids. Ever since @NASA crashed the DART probe into this asteroid's little moon, we've been tracking the result. Now we know its 770-day orbit around the Sun changed by a fraction of a second. That's enough to defend our Earth. The dinosaurs wish they'd had a space program! details: jpl.nasa.gov/news/nasas-dart…
