On Thursday, Jan. 26, a small near-Earth asteroid will have a very close encounter with our planet. Designated 2023 BU, the asteroid will zoom over the southern tip of South America at about 4:27 p.m. PST (7:27 p.m. EST) only 2,200 miles (3,600 kilometers) above the planet’s surface and well within the orbit of geosynchronous satellites.
There is no risk of the asteroid impacting Earth. But even…
NASA’s Psyche Mission Continues Preparation for Launch in 2023
January 26, 2023
NASA’s Psyche spacecraft is shown in a clean room on Dec. 8, 2022, at Astrotech Space Operations Facility near the agency’s Kennedy Space Center in Florida. The spacecraft was powered on and connected to ground support equipment, enabling engineers and technicians to…
In a recent study, scientists found that a previously unmeasured source – water percolating through soil and fractured rock below California’s Sierra Nevada mountains – delivers an average of 4 million acre feet (5 cubic kilometers) of water to the state’s Central…
NASA’s Lunar Flashlight mission successfully launched on Dec. 11, 2022, to begin its four-month journey to the Moon, where the small satellite, or SmallSat, will test several new technologies with a goal of looking for hidden surface ice at the lunar South Pole. While the SmallSat is largely healthy and communicating with NASA’s Deep Space Network, the mission operations team has discovered…
Creeping, rising, falling, slipping – some parts of Earth are in perpetual motion. The movements are usually too tiny for human senses to notice, but they offer clues about more significant changes happening inside volcanoes, along fault lines, and where tectonic plates…
NASA Wants You to Help Study Planets Around Other Stars
January 11, 2023
More than 5,000 planets have been confirmed to exist outside our solar system, featuring a wide array of characteristics like clouds made of glass and twin suns. Scientists estimate there could be millions more exoplanets in our home galaxy alone, which means professional…
NASA’s TESS Discovers Planetary System’s Second Earth-Size World
January 11, 2023
Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.
Astronomers previously discovered three planets in this system, called TOI 700 b, c, and…
NASA Space Missions Pinpoint Sources of CO2 Emissions on Earth
January 10, 2023
A duo of Earth-observing missions has enabled researchers to detect and track carbon dioxide (CO2) emission changes from a single facility, using the world’s fifth-largest coal-fired power plant as a test case.
In the recent study, researchers used space-based measurements…
Watch the Latest Water Satellite Unfold Itself in Space
December 29, 2022
The Surface Water and Ocean Topography (SWOT) satellite launched into Earth orbit on Friday, Dec. 16, from Vandenberg Space Force Base in central California, and engineers are working to prepare the mission to begin measuring the height of water on over 90% of Earth’s…
NASA Explores a Winter Wonderland on Mars
December 23, 2022
When winter comes to Mars, the surface is transformed into a truly otherworldly holiday scene. Snow, ice, and frost accompany the season’s sub-zero temperatures. Some of the coldest of these occur at the planet’s poles, where it gets as low as minus 190 degrees Fahrenheit (minus 123 degrees Celsius).
Cold as it is, don’t expect snow drifts worthy of the Rocky Mountains. No region of Mars…
