Measuring the fuel supply on Odyssey, a decades-old spacecraft without a fuel gauge, is no easy task. Since NASA launched the 2001 Mars Odyssey Orbiter to the Red Planet almost 22 years ago, the spacecraft has looped around Mars more than 94,000 times. That’s about the equivalent of 1.37 billion miles (2.21 billion kilometers), a …

Every six months, NASA’s Near-Earth Object Wide Field Infrared Survey Explorer, or NEOWISE, spacecraft completes one trip halfway around the Sun, taking images in all directions. Stitched together, those images form an “all-sky” map showing the location and brightness of hundreds of millions of objects. Using 18 all-sky maps produced by the spacecraft (with …

Scientists have discovered a new source of ‘electron rain’ that is showering Earth with particles, a phenomena that could have a hazardous effect on satellites, spacecraft and astronauts. Rapid “electron precipitation” is caused by whistler waves, a type of electromagnetic wave that ripples through plasma in space and affects electrons in the Earth’s magnetosphere. Researchers …
The two agencies are partnering on a satellite to understand the effects of different types of particle pollution on human health. NASA and the Italian space agency Agenzia Spaziale Italiana (ASI) are partnering to build and launch the Multi-Angle Imager for Aerosols (MAIA) mission, an effort to investigate the health impacts of tiny airborne …

Dignitaries from the U.S. and Indian space agencies, along with members of the media, were invited to see NISAR’s science payload in a Jet Propulsion Laboratory clean room. It’s nearly time for the scientific heart of NISAR – short for NASA-ISRO Synthetic Aperture Radar – an Earth science satellite being jointly built by …

Cambridge, Mass. – For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star. The stricken world appears destined to spiral closer and closer to its maturing star until collision and ultimate obliteration. The discovery offers new insights into the long-winded process of planetary orbital decay …

The veteran rover captured a dazzling sunset at the start of a new cloud-imaging campaign. Martian sunsets are uniquely moody, but NASA’s Curiosity rover captured one last month that stands out. As the Sun descended over the horizon on Feb. 2, rays of light illuminated a bank of clouds. These “sun rays” are also known …
The research uses archival NASA data to show that Venus may be losing heat from geologic activity in regions called coronae, possibly like early tectonic activity on Earth. Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the …

Future planetary missions could explore in extremely cold temperatures that stymie existing spacecraft, thanks to a project under development at JPL. When NASA returns to the Moon with Artemis, the agency and its partners will reach unexplored regions of the lunar surface around the South Pole, where it can get much colder at night than …

The Egyptian Space Agency (EgSA) CEO, Prof Sherif Sedky, announced that Egypt had added another Earth observation (EO) satellite to its fleet after successfully launching the Horus-1 satellite into the sun-synchronous polar orbit. Horus-1 was onboard China’s Long March 2C (Chang Zheng 2C), launched successfully on 24 February 2023 from the SLS-2 pad at the …
