Organized by the Science Mission Directorate’s Science Support Office (SSO), NASA hosted its 12th annual Earth Day Celebration event from April 18–19, 2024. For the first time ever, the two-day event was held at NASA Headquarters (HQ) in Washington, DC.
The in-person event, which was free and open to the public, featured the newly installed Earth Information Center (EIC) exhibit – see Photos 1–4. The event featured 17 hands-on activities offered in NASA HQ’s East Lobby as well as two adjacent outdoor tents. Event participants were given an activity passport called the “Passport to Fun” listing all the activities and encouraging attendees to visit the stations and interact with NASA staff – see Figure 1. After completing six or more activities, attendees were able to claim giveaway items, e.g., lenticulars, NASA bags, posters, and calendars.

This included over 300 students from DuVal High School, Morgan State University, Howard University, Prince George’s County Environmental Academy, Prince George’s County Virtual Academy, International Hispanic School, and homeschoolers. On April 19, all of the students who were present at that time gathered for a plenary in the Webb Auditorium. Ferrell welcomed the attendees and provided introductions to prepare them for a virtual presentation by former NASA astronaut Paul Richards, who interacted with attendees and answered questions for roughly 20 minutes.
After Richard’s presentation, the attendees heard from Karen St. Germain [NASA HQ—Director of NASA’s Earth Science Division], whose in-person remarks emphasized to the students the crucial albeit less publicized studies that NASA does of our home planet. Related to this year’s Earth Day theme, “Water Touches Everything,” she discussed the ability of NASA’s Earth observing satellites to track water in all its forms as it circulates throughout the Earth system. St. Germain then answered questions from the audience for 15 minutes – see Photos 5–8.

NASA Administrator Bill Nelson visited the event on April 19, accompanied by Karen St. Germain and several NASA staff members who guided him as he explored the activities offered – see Photos 9–10.

Throughout the two-day event, it is estimated that as many as 1500 public participants attended along with the 300 students already discussed. While SSO staff distributed 500 activity passports, many small groups and families shared a single passport. SSO staff estimates that the true number of participants may be close to 1500 – see Photos 11–19.

Conclusion
NASA’s first Earth Day Celebration at NASA Headquarters was quite successful. While attendance was lower than previous events held at the more heavily trafficked Union Station or the National Mall, there was a steady stream of people throughout the exhibit on both days. It was also a great opportunity to showcase the new EIC to the public. Earth Day is the largest event organized annually by the SSO. This event requires months of planning, cross-divisional coordination, and intensive design of the hands-on activities – all carried from conceptualization through numerous revisions to implementation by more than 100 individuals from across the agency. This combined effort of SSO staff and assisting organizations results in an event that brings together thousands of visitors from a broad spectrum of ages and backgrounds to enjoy NASA science. This event would not have been possible were it not for the incredible efforts and collaboration put forth by so many of NASA’s outreach professionals. The SSO is grateful for all who helped to make this year’s Earth Day event a success and looks forward to Earth Day 2025.

Hubble Traces Star Formation in a Nearby Nebula
NASA, ESA, and L. C. Johnson (Northwestern University); Image Processing: Gladys Kober (NASA/Catholic University of America) NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA’s Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way’s closest galactic companions, the Small Magellanic Cloud (SMC). The ionized gas blazing from within this diffuse region marks NGC 261 as an emission nebula. It is home to numerous stars hot enough to irradiate surrounding hydrogen gas, causing the cloud to emit a pinkish-red glow.
This inset image shows the location of NGC 261 within the Small Magellanic Cloud. NASA, ESA, L. C. Johnson (Northwestern University), and ESO/VISTA VMC; Image Processing: Gladys Kober (NASA/Catholic University of America) Hubble turned its keen eye toward NGC 261 to investigate how efficiently stars form in molecular clouds, which are extremely dense and compact regions of gas and dust. These clouds often consist of large amounts of molecular hydrogen — cold areas where most stars form. However, measuring this raw fuel of star formation in stellar nurseries is a challenge because molecular hydrogen doesn’t radiate easily. Since it is difficult to detect, scientists instead trace other molecules present in the molecular clouds.
The SMC hosts a gas-rich environment of young stars along with trace amounts of carbon monoxide (CO), a chemical correlated with hydrogen and often used to identify the presence of such clouds. Using the Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3), Hubble imaged these stars in the southwest portion of the SMC where NGC 261 resides. The combined power of ACS and WFC3 allowed scientists to closely examine the nebula’s star-forming properties through its CO content at optical and near-infrared wavelengths. This research helps astronomers better understand how stars form in our home galaxy and others in our galactic neighborhood.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Early research at NASA’s Ames Research Center in California’s Silicon Valley — then known as NACA Ames Aeronautical Laboratory – included ground tests of “hot wing” anti-icing systems on a Lockheed 12A aircraft. NASA works every day to improve air travel – and has been doing so since its creation decades ago. On National Aviation Day, NASA and all fans of aviation get the chance to celebrate the innovative research and development the agency has produced to improve capability and safety in flight.
NASA’s Ames Research Center in California’s Silicon Valley has a historic legacy in aeronautics research. When the center was founded in 1939 by the National Advisory Committee for Aeronautics (NACA), its early research included working to reduce icing on aircraft wings.
When ice coats the wings of an airplane, it reduces lift and increases drag, which can cause the aircraft to lose altitude and control. Ames researchers developed different approaches to solve the icing challenge, including a “hot wing” thermal anti-icing system. The system worked by running hot engine exhaust along the leading edges of aircraft wings, warming them and preventing ice buildup. Ames researchers modified aircraft and tested them before traveling to Minnesota, where they were flown in icy conditions.
Today, many turbine-powered aircraft, like passenger jets, use “bleed air” anti-icing systems, which warm the leading edges of aircraft wings using compressed air from their engines. These systems are built upon the early research and testing done at Ames.
The legacy of aviation innovation continues at Ames, through aeroscience research like wind tunnel testing, air traffic management, and advanced aircraft systems.
