This one-of-a-kind comet aurora could help make crewed Mars missions safer

This one-of-a-kind comet aurora could help make crewed Mars missions safer

A mysterious ultraviolet glow spotted for the first time around a comet could help pave the way to protecting astronauts from solar radiation, NASA has said today. The new research into data gathered by the Rosetta mission to comet 67P/Churyumov-Gerasimenko overturns an old theory about the unusually-shaped rock's aura, and presents a far more fascinating possibility.

NASA says Artemis astronauts may not visit the lunar South Pole

NASA says Artemis astronauts may not visit the lunar South Pole

NASA has had a primary focus for many months on putting astronauts back on the moon in 2024. The space agency originally said that the astronauts would be placed on the moon's south pole, but that may be changing. The Artemis program's landing site was the subject of two separate events held by agency leaders recently. The first was with NASA administrator Jim Bridenstine in a digital meeting held by the NASA advisory group called the Letter Exploration Analysis Group.

ESA funds Hera mission as part of planetary defense project with NASA

The European Space Agency has announced the funding of Hera, its part of the overall AIDA mission it will participate in with NASA. The Hera mission will involve sending a probe to investigate the impact of a NASA mission on an asteroid, two aspects of an overall mission designed to help protect our planet from asteroids. The awarded contract covers spacecraft design and more.

NASA talks about new precision landing technology that needs no pilot

NASA talks about new precision landing technology that needs no pilot

One of the riskiest parts of exploring another planet or moon is the landing. Often, landing sites, particularly on the moon, are covered in rocks and craters. NASA has robotic and crewed missions to the moon, and Mars planned for the future. One challenge of the landing process is avoiding landing on the steep slope of a crater or in a boulder field.

NASA says Jupiter’s Great Red Spot has a cousin and it’s changing color

NASA says Jupiter’s Great Red Spot has a cousin and it’s changing color

NASA has published the most recent up-close image of Jupiter, the massive planet covered with beautiful, terrifying storms. The image was captured on August 25 by the Hubble Space Telescope, giving researchers an updated look at the planet and its recent changes. Most notable among those changes is, according to NASA, the Great Red Spot's 'cousin' and its morphing color.

NASA-led ice melt study makes a terrifying prediction about rising sea levels

NASA-led ice melt study makes a terrifying prediction about rising sea levels

Unchecked greenhouse gas emissions could lead to more than a 15-inch rise in sea levels, scientists have concluded, using NASA data to issue a stark warning about melting ice sheets. The huge rise would lead to dramatic flooding in coastal regions around the world, and create a potentially apocalyptic chain reaction of consequences.

NASA’s stealthy supersonic X-59 just got a schedule change

NASA’s stealthy supersonic X-59 just got a schedule change

NASA has pushed back the maiden flight of its experimental X-59 Quiet SuperSonic aircraft, confirming today that the sound-barrier-breaking jet won't be ready in time for the original 2021 launch plan. Currently in production and assembly, the X-59 will test a cutting-edge engine and body design that could eventually help remedy one of Concorde's most significant problems.

TESS and Spitzer discover planet closely orbiting a white dwarf star

TESS and Spitzer discover planet closely orbiting a white dwarf star

NASA has announced that the Transiting Exoplanet Survey Satellite (TESS) and the now-retired Spitzer Space Telescope discovered the first intact planet found closely orbiting a white dwarf star. The white dwarf star is the dense remnant of a Sun-like star that is only 40 percent larger than the Earth. The planet orbiting the star is the size of Jupiter and is called WD 1856 b. It's about seven times larger than the star it orbits.

NASA says Solar Cycle 25 has begun

NASA says Solar Cycle 25 has begun

The sun goes through cycles where it has more or less activity, and NASA has now confirmed that Solar Cycle 25 has begun. Experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) discussed analysis and predictions about the new solar cycle during a media event on Tuesday of this week. Among the information shared during the event was how the coming upswing in space weather impacts life on Earth, technology, and astronauts in space.

Hubble snaps stunning image with thousands of multi-colored stars

Hubble snaps stunning image with thousands of multi-colored stars

NASA's aging Hubble Space Telescope has snapped an image showing 'a pocketful of stars,' according to the space agency -- a cluster of the universe packed full of thousands of stars with different colors. The stars range in size from quite small to very large, painting a colorful picture of celestial bodies located so closely together that they've likely crowded out any hope of surrounding planet systems.

NASA wants private companies to sell it Moon rocks and dust

NASA wants private companies to sell it Moon rocks and dust

NASA has announced a new contract opportunity that will involve it purchasing Moon dust (called regolith) and rocks from a private space company. The intention was announced by NASA Administrator Jim Bridenstine in a post this week, with the official stating that utilizing private companies under its Artemis lunar program will help it save money and access new innovations developed by these companies. The new contract is part of this effort.

OSIRIS-REx observes asteroid Bennu particle ejection events up close

OSIRIS-REx observes asteroid Bennu particle ejection events up close

Researchers in charge of the OSIRIS-REx mission have reported detailed observations of asteroid Bennu shedding material regularly. The spacecraft has provided scientists with the ability to observe the asteroid's activity at close range for the first time. The surface of the asteroid is highly active and builds a picture of asteroids as being very dynamic.
