What's Going on with the Hole in the Earth's Ozone Layer? We Asked a NASA Expert

What's going on with the hole in the ozone layer?

Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century. Well done, world.

However, at NASA, scientists continue to monitor its progress. NASA Goddard’s Qing Liang explains more. Background info:

Does this Exoplanet have a “Sibling” Sharing the Same Orbit? | ESO

ESOcast 263 Light: Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have found  the possible ‘sibling’ of a planet orbiting a distant star. This video summarizes the discovery. The system features a star at its center, around which the planet PDS 70b (highlighted with a solid yellow circle) is orbiting. On the same orbit as PDS 70b, indicated by a solid yellow ellipse, astronomers have detected a cloud of debris (circled by a yellow dotted line) that could be the building blocks of a new planet or the remnants of one already formed. The ring-like structure that dominates the image is a circumstellar disc of material, out of which planets are forming. There is in fact another planet in this system: PDS 70c, seen at 3 o’clock right next to the inner rim of the disc.

Messier 81: Optical, Ultraviolet & Infrared Views Combined | Hubble/GALEX/Spitzer

Messier 81: Optical, Ultraviolet & Infrared Views Combined | Hubble/GALEX/Spitzer


This image combines data from the Hubble Space Telescope, the Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX) missions. The GALEX ultraviolet data were from the far-UV portion of the spectrum (135 to 175 nanometres). The Spitzer infrared data were taken with the IRAC 4 detector (8 microns). The Hubble data were taken at the blue portion of the spectrum.

Messier 81 (M81) is a spiral-shaped system of stars, dust, and gas clouds—the galaxy's arms wind all the way down into the nucleus. M81 is located 11.6 million light-years away. The M81 galaxy's large size and relatively high brightness make it a popular target for amateur astronomers. In the midsts of this galaxy is the supernova 1993J which was recently found to have a companion star which had been hidden in the glow of the supernova for 21 years.

Mars: Colors of the Undiscovered Country | NASA Mars Reconnaissance Orbiter

Mars: Colors of the Undiscovered Country | NASA Mars Reconnaissance Orbiter

Nili Fossae is one of our favorite places to image due to the incredibly dense terrain here where clays have been detected. For this reason, Nili Fossae has long been on the short-list for potential landings for robotic exploration. However, this image shows us how rugged (and dangerous) the landscape can be. We acquired this image to study the diverse mineralogy and gain HiRISE coverage over existing high-resolution CRISM data. (CRISM is a spectrometer also onboard the Mars Reconnaissance Orbiter.)

This clip features the center swath of the full observation, utilizing the infrared-red-blue (IRB) filter of the HiRISE camera. Enhanced color can help us see details that we do not otherwise view in black and white. It would not appear like to this to our eyes if we were there.

This is a non-narrated clip with ambient sound. Image is less than 1 km (under one mile) across and the spacecraft altitude was 282 km (175 mi).

These images were acquired on April 28, 2022, by NASA's Mars Reconnaissance Orbiter (MRO) at an altitude of 281 km from the planet's surface. The image is less than 1 km across. 

The University of Arizona, Tucson, operates the High Resolution Imaging Science Experiment (HiRISE) instrument, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. 

NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.

“For 17 years, MRO has been revealing Mars to us as no one had seen it before,” said the mission’s project scientist, Rich Zurek of JPL.

Swarm Technology in Space with NASA's Starling Mission

Swarm Technology in Space with NASA's Starling Mission

NASA has sent a team of four CubeSats into orbit around Earth to see if they are able to cooperate on their own, without real-time updates from mission control. While that kind of autonomous cooperation may not sound too difficult for humans, this team will be robotic—composed of small satellites to test out key technologies for the future of deep space missions.

The Rocket Labs ‘Baby Come Back’ Electron rocket mission lifted off successfully from Rocket Lab Launch Complex 1 in New Zealand on July 18 (NZST), 2023, with NASA’s Starling Mission.

Starling is funded by NASA’s Small Spacecraft Technology program based at NASA’s Ames Research Center in California’s Silicon Valley and within the agency’s Space Technology Mission Directorate in Washington.

Rocket Lab's Electron Launches NASA Starling CubeSat Mission in New Zealand

Rocket Lab's Electron Launches NASA Starling CubeSat Mission in New Zealand

The ‘Baby Come Back’ Electron rocket mission lifted off successfully from Rocket Lab Launch Complex 1 in New Zealand on July 18 NZST, 2023, with NASA’s Starling Mission consisting of four CubeSats designed to advance technologies for cooperative groups of spacecraft—also known as swarms. Spacecraft swarms refer to multiple spacecraft autonomously coordinating their activities on orbit. Once positioned in orbit around Earth and spaced about 40 miles/64 km apart, Starling’s spacecraft will demonstrate the ability to autonomously fly together while keeping track of each other’s relative positions and trajectories. They also will demonstrate the ability to plan and execute activities as a group, without guidance from mission controllers, including responding to new information from onboard sensors. Starling’s spacecraft will also demonstrate creating and maintaining an inter-spacecraft communications network that automatically adjusts to changing conditions. The Starling mission will test whether the technologies work as expected, what their limitations are, and what developments are still needed for CubeSat swarms to be successful.

Learn more about NASA's Starling Mission: 

Baby Come Back launched a total of seven satellites to a sun synchronous orbit for three customers: NASA, Space Flight Laboratory and Spire Global. Baby Come Back is Rocket Lab’s seventh Electron launch of 2023, 39th Electron launch overall, and the Company’s second recovery mission this year.  After launch, Electron’s first stage returned to Earth under a parachute and completed a soft splashdown in the Pacific Ocean. Rocket Lab’s marine recovery vessel then extracted the stage from the ocean and transported it back to Rocket Lab’s production complex for analysis.

This Electron first stage features new recovery upgrades including waterproofing systems to protect key engine and avionics components. Rocket Lab’s transition to marine recovery away from mid-air capture has been informed by previous recovery missions that showed Electron components and engines passed requalification testing following ocean splashdowns. This mission represents near final maturation of the marine recovery system in preparation for reflight of a booster.

Beaver Rewilding Impacts Measured by NASA in Idaho

Beaver Rewilding Impacts Measured by NASA in Idaho

When beavers build dams, the changes they make to their habitat can improve everything from biodiversity to drought resilience. Researchers at Boise State University and Utah State University, in collaboration with NASA’s Applied Sciences Ecological Conservation program area, are adding remote sensing data to a suite of tools to measure what happens when beaver are reintroduced to an area.

For people managing water resources and conservation efforts, predicting which streams can support beavers and monitoring how water and vegetation change once they return is critical. Using satellite data makes it possible to monitor large areas and track changes over time.
