Dear Reader,

This week, we're shouting into the void—or planning to, anyway. Our lead story covers a new attempt to craft a cosmic message to extraterrestrial civilizations, and details why such transmissions make some scientists uneasy. Elsewhere, we have stories on a record-breaking stellar discovery from the Hubble Space Telescope, bizarre "space circles" spied by sharp-eyed radio astronomers, a new approach to energy-efficient computing and more. And finally, be sure to check out the second season premiere of our "Lost Women in Science" podcast, which this time around spotlights the remarkable life and work of Klára von Neumann.

QUOTE OF THE DAY

"People have problems on Earth. On orbit, we are one crew. I think ISS is a symbol of the friendship and cooperation, like symbol of the future exploration of space."

Anton Shkaplerov, Russian cosmonaut

NASA EXPRESS -- Your STEM Connection for March 31, 2022

Last week, an incredible milestone was reached: more than 5,000 planets are now confirmed to exist beyond our solar system. Explore the STEM resources below to learn more about the variety of exoplanets that have been discovered.
This weekend, NASA will conduct the final major test of the Space Launch System rocket and Orion spacecraft ahead of the Artemis I mission.
 
Are you looking to share the excitement of Artemis with your STEM learners?

Leading up to launch, NASA’s Artemis I STEM Learning Pathway will provide weekly newsletters filled with STEM resources and ready-to-use content. Each week’s resources can be used individually or in combination to create a lesson plan tied to the learning series’ weekly theme.
 
Are you ready to sign up? Click here to register and select the “Artemis I STEM Learning Pathway” add-on option.
Audience: Community College Students
Application Deadline: April 6
 
NASA Community College Aerospace Scholars (NCAS) aims to build a diverse future STEM workforce by engaging two-year degree-seeking students in authentic learning experiences. Applications for “Mission 1: Discover” are open now. Participants will take part in a five-week, self-paced online course introducing scholars to NASA missions and research. NCAS is open to community college students who are U.S. citizens. Click here to learn more.
Join the NASA STEM Engagement & Educator Professional Development Collaborative at Texas State University for educator professional development webinarsAttendees earn a certificate that can be submitted for
professional development hours.
April 4 at 6 p.m. EDT
April 5 at 5 p.m. EDT
April 7 at 5 p.m. EDT
For a full list of upcoming webinars, click here.
Audience: Formal and Informal Educators, Parents, Caregivers, and Learners
Webinar Date: April 5 at 5 p.m. EDT
 
Join the NASA eClips team for an overview of the NASA Spotlite Video Design Challenge co-developed with the NASA Earth Science Education Collaborative. NASA Spotlites are 90- to 120-second videos that are written, filmed, edited, and produced by students using the engineering design process. Each video targets a science misconception.
 
Webinar attendees will focus on cloud misconceptions and learn how to use the GLOBE Cloud Observer app to collect evidence to correct them. Participants also will learn how to use free resources to film, edit, and publish videos.
 
Ready to get started producing NASA Spotlite videos? Click here to sign up production teams.
Audience: Rural Educators in the U.S.
Event Date: April 7 at 8 p.m. EDT
 
Join NASA’s Science Mission Directorate for a monthly series that connects rural educators to resources, networking, and professional development opportunities. This month’s webinar will focus on STEM resources to celebrate Earth Day. Special guest Dr. Trena Ferrell will discuss ways to engage your students with NASA-supported Earth Day activities and resources. Click here to register to attend.
Audience: High School and College Students, and Citizen Scientists
 
The Radio JOVE Project announces Radio JOVE 2.0, a new radio astronomy telescope kit for beginner and advanced citizen scientists to observe radio emissions from the Sun, Jupiter, the Milky Way, and Earth-based sources. Participants assemble and operate a 16-24 MHz radio spectrograph, make scientific observations, and interact with near-professional radio observatories in real time over the Internet. The project can be utilized in high school and college science classes and extracurricular groups. Advanced projects are available.
Audience: Educators, Parents, Caregivers, and Students Ages 11+
 
A thorough understanding of the electromagnetic spectrum is critical to NASA’s space exploration, Earth observation, and more.

Practice your mastery of the different attributes of waves with this quick, fun quiz from NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Test your knowledge as a class, assign a quiz to students individually, or arrange a team competition.
