The Surface Water and Ocean Topography mission will explore how the ocean absorbs atmospheric heat and carbon, moderating global temperatures and climate change.
PASADENA, Calif. (NASA PR) — Though climate change is driving sea level rise over time, researchers also believe that differences in surface height from place to place in the ocean can affect Earth’s climate. These highs and lows are associated with currents and eddies, swirling rivers in the ocean, that influence how it absorbs atmospheric heat and carbon.
Eyeing some of the components that enabled the rover to get safely to the Martian surface could provide valuable insights for future missions.
PASADENA, Calif. (NASA PR) — NASA’s Ingenuity Mars Helicopter recently surveyed both the parachute that helped the agency’s Perseverance rover land on Mars and the cone-shaped backshell that protected the rover in deep space and during its fiery descent toward the Martian surface on Feb. 18, 2021. Engineers with the Mars Sample Return program asked whether Ingenuity could provide this perspective. What resulted were 10 aerial color images taken April 19 during Ingenuity’s Flight 26.
WASHINGTON (NASA PR) — Following a thorough evaluation, NASA has extended the planetary science missions of eight of its spacecraft due to their scientific productivity and potential to deepen our knowledge and understanding of the solar system and beyond.
The missions – Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Mars Science Laboratory (Curiosity rover), InSight lander, Lunar Reconnaissance Orbiter, OSIRIS-REx, and New Horizons – have been selected for continuation, assuming their spacecraft remain healthy. Most of the missions will be extended for three years; however, OSIRIS-REx will be continued for nine years in order to reach a new destination, and InSight will be continued until the end of 2022, unless the spacecraft’s electrical power allows for longer operations.
PASADENA, Calif. (NASA PR) — NASA’s Perseverance Mars rover has captured dramatic footage of Phobos, Mars’ potato-shaped moon, crossing the face of the Sun. These observations can help scientists better understand the moon’s orbit and how its gravity pulls on the Martian surface, ultimately shaping the Red Planet’s crust and mantle.
PARIS (ESA PR) — With help from a cryocooler, Webb’s Mid-Infrared Instrument has dropped down to just a few degrees above the lowest temperature matter can reach and is ready for calibration.
The James Webb Space Telescope will see the first galaxies to form after the Big Bang, but to do that its instruments first need to get cold – really cold. On 7 April, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by ESA and NASA – reached its final operating temperature below 7 kelvins (minus 266 degrees Celsius).
Hosted by JPL’s Center for Near Earth Object Studies, the data can be used by the science community to better understand how asteroids break up when entering the atmosphere.
PASADENA, Calif. (NASA PR) — An agreement between NASA and the U.S. Space Force recently authorized the public release of decades of data collected by U.S. government sensors on fireball events (large bright meteors also known as bolides) for the benefit of the scientific and planetary defense communities. This action results from collaboration between NASA’s Planetary Defense Coordination Office (PDCO) and the U.S. Space Force to continue furthering our nation’s efforts in planetary defense, which include finding, tracking, characterizing, and cataloguing near-Earth objects (NEOs). The newly released data is composed of information on the changing brightness of bolides as they pass through Earth’s atmosphere, called light curves, that could enhance the planetary defense community’s current ability to model the effects of impacts by larger asteroids that could one day pose a threat to Earth.
Sentinel-6 Michael Freilich, the newest addition to a long line of ocean-monitoring satellites, becomes the reference satellite for sea level measurements.
PASADENA, Calif. (NASA PR) — On March 22, the newest U.S.-European sea level satellite, named Sentinel-6 Michael Freilich, became the official reference satellite for global sea level measurements. This means that sea surface height data collected by other satellites will be compared to the information produced by Sentinel-6 Michael Freilich to ensure their accuracy.
PASADENA, Calif. (NASA PR) — Asteroid 2022 EB5 was too small to pose a hazard to Earth, but its discovery marks the fifth time that any asteroid has been observed before impacting into the atmosphere.
A small asteroid hit Earth’s atmosphere over the Norwegian Sea before disintegrating on March 11, 2022. But this event wasn’t a complete surprise: Astronomers knew it was on a collision course, predicting exactly where and when the impact would happen.
Scientists are turning to a combination of data collected from the air, land, and space to get a more complete picture of how climate change is affecting the planet’s frozen regions.
PASADENA, Calif. (NASA PR) — Trapped within Earth’s permafrost – ground that remains frozen for a minimum of two years – are untold quantities of greenhouse gases, microbes, and chemicals, including the now-banned pesticide DDT. As the planet warms, permafrost is thawing at an increasing rate, and scientists face a host of uncertainties when trying to determine the potential effects of the thaw.
LAUREL, Md. (NASA PR) — This past month, NASA, FEMA, the United States Space Command, and other federal, state and local agencies convened for the fourth iteration of a Planetary Defense Interagency Tabletop Exercise to inform and assess our nation’s ability to respond effectively to a (simulated) asteroid impact threat to Earth. While there are no predicted asteroid impact threats to our planet for the foreseeable future, this exercise—sponsored by NASA and FEMA and hosted by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland—focused extensively on federal and state government coordination that would be necessary to respond to such a threat should one ever be discovered.

Science instruments and other hardware for the spacecraft will come together in the mission’s final phase before a launch to Jupiter’s icy moon Europa in 2024.
PASADENA, Calif. (NASA PR) — When it’s fully assembled, NASA’s Europa Clipper will be as large as an SUV with solar arrays long enough to span a basketball court – all the better to help power the spacecraft during its journey to Jupiter’s icy moon Europa. And just about every detail of the spacecraft will have been hand-crafted.
