NASA's Europa Clipper spacecraft, headed to Jupiter's ice-covered moon Europa in October 2024, will carry a laser-etched message that celebrates humanity's connection to water. The message pays homage to past NASA missions that carried similar messages.

As the president of Messaging Extraterrestrial Intelligence, or METI, International, I helped design the message on Clipper with two fellow members of our board of directors: linguists Sheri Wells-Jensen and Laura Buszard-Welcher. METI International is a scientific organization dedicated to transmitting powerful radio messages to extraterrestrial life.

We collected audio recordings in 103 languages, and we decided how to convert these into waveforms that show these sounds visually. Colleagues from NASA etched these waveforms into the metal plate that shields the spacecraft's sensitive electronics from Jupiter's harsh radiation.

In the dark, early morning sky of March 21 over NASA's Wallops Island Flight Facility on the Virginia coast, a Rocket Lab Electron rocket carried a National Reconnaissance Office (NRO) manifest featuring three collaborative research missions into low-Earth orbit—including the latest piece of home-grown space hardware from the Naval Postgraduate School (NPS).

Massive cost overruns. Key deadlines slipping out of reach. Problems of unprecedented complexity, and a generation's worth of scientific progress contingent upon solving them.

That's the current state of Mars Sample Return, the ambitious yet imperiled NASA mission whose rapidly ballooning budget has cost jobs at NASA's Jet Propulsion Laboratory in La Cañada Flintridge and drawn threats of cancellation from lawmakers.

But not all that long ago, those same dire circumstances described the James Webb Space Telescope, the pioneering infrared scope that launched on Christmas Day 2021.

The biggest space telescope ever has so far proved to be a scientific and public relations victory for NASA. The telescope's performance has surpassed all expectations, senior project scientist Jane Rigby said at a meeting recently.

Its first images were so hotly anticipated that the White House scooped NASA's announcement, releasing a dazzling view of thousands of galaxies the day before the space agency shared the first batch of pictures. Thousands of researchers have since applied for observation time.

"The world has been rooting for this telescope to succeed," Rigby told the National Academies' committee on astronomy and astrophysics.
