Pasadena, CA – The team of scientists and engineers behind NASA’s Curiosity rover named a hill along the rover’s path on Mars in honor of a recently deceased mission scientist. A craggy hump that stretches 450 feet (120 meters) tall, “Rafael Navarro Mountain” is located on Mount Sharp in northwest Gale Crater.
Greenbelt, MD – Space communications and navigation engineers at NASA are evaluating the navigation needs for the Artemis program, including identifying the precision navigation capabilities needed to establish the first sustained presence on the lunar surface.
“Artemis engages us to apply creative navigation solutions, choosing the right combination of capabilities for each mission,” said Cheryl Gramling, associate chief for technology in the Mission Engineering and Systems Analysis Division at Goddard Space Flight Center in Greenbelt, Maryland.
Greenbelt, MD – Look up to the night sky just before dawn, or after dusk, and you might see a faint column of light extending up from the horizon. That luminous glow is the zodiacal light, or sunlight reflected toward Earth by a cloud of tiny dust particles orbiting the Sun.
Astronomers have long thought that the dust is brought into the inner solar system by a few of the asteroid and comet families that venture in from afar.
But now, a team of Juno scientists argues that Mars may be the culprit. They published their finding in a March 9th paper in the Journal of Geophysical Research: Planets.
Greenbelt, MD – To investigate humans’ impact on freshwater resources, scientists have now conducted the first global accounting of fluctuating water levels in Earth’s lakes and reservoirs – including ones previously too small to measure from space.
The research, published March 3rd in the journal Nature, relied on NASA’s Ice, Cloud, and land Elevation Satellite 2 (ICESat-2), launched in September 2018.
Greenbelt, MD – February marked significant progress for NASA’s James Webb Space Telescope, which completed its final functional performance tests at Northrop Grumman in Redondo Beach, California.
Testing teams successfully completed two important milestones that confirmed the observatory’s internal electronics are all functioning as intended, and that the spacecraft and its four scientific instruments can send and receive data properly through the same network they will use in space. These milestones move Webb closer to being ready to launch in October.
Pasadena, CA – NASA reports that for the first time, a wayward comet-like object has been spotted near the family of ancient asteroids.
After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.
Greenbelt, MD – NASA is improving a flight software system to help create and certify essential software for the lunar Gateway.
As part of the Artemis program, NASA will send astronauts to the Moon and establish a sustained lunar presence by the end of the decade. The Gateway will provide a waypoint for lunar exploration and allow astronauts to live and work in lunar orbit as well as host science instruments and experiments.
Greenbelt, MD – Astronomers found something they weren’t expecting at the heart of the globular cluster NGC 6397: a concentration of smaller black holes lurking there instead of one massive black hole.
Globular clusters are extremely dense stellar systems, which host stars that are closely packed together. These systems are also typically very old — the globular cluster at the focus of this study, NGC 6397, is almost as old as the universe itself. This cluster resides 7,800 light-years away, making it one of the closest globular clusters to Earth. Due to its very dense nucleus, it is known as a core-collapsed cluster.
Washington, D.C. – NASA has selected Space Exploration Technologies (SpaceX) of Hawthorne, California, to provide launch services for the Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer (SPHEREx) mission.
SPHEREx is a planned two-year astrophysics mission to survey the sky in the near-infrared light, which, though not visible to the human eye, serves as a powerful tool for answering cosmic questions involving the birth of the universe, and the subsequent development of galaxies.
Greenbelt, MD – The Martian moon Phobos orbits through a stream of charged atoms and molecules that flow off the Red Planet’s atmosphere, new NASA research shows.
Many of these charged particles, or ions, of oxygen, carbon, nitrogen, and argon, have been escaping Mars for billions of years as the planet has been shedding its atmosphere. Some ions, scientists predict, have been smashing into the surface of Phobos and could be preserved in its uppermost layer, according to a paper published on February 1st in the journal Nature Geoscience.
