NASA’s Juno Orbiter Captures Stunning Images of Jupiter’s Moon Io
On February 3, 2024, NASA’s Juno spacecraft made a second close flyby of Io, the fifth of Jupiter’s moons and the third largest. Like the previous flyby on December 30, 2023, this second pass was at a distance of about 1,500 km (930 miles). During the twin flybys, the spacecraft’s JunoCam instrument returned spectacular, high-resolution
NASA’s PACE Mission Faces Another Launch Delay Due to Weather Challenges
A SpaceX Falcon 9 rocket with NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) spacecraft stands vertical at Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida on Monday, February 5, 2024. PACE is NASA’s newest earth-observing satellite that will help increase our understanding of Earth’s oceans, atmosphere, and climate by delivering hyperspectral
NASA’s Perseverance rover may already have found signs of life on Mars, discovery of ancient lake sediments reveals

NASA’s Hubble Finds Water Vapor in Small Exoplanet’s Atmosphere
Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth's diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.However, it remains too early to tell whether Hubble spectroscopically measured a small
Hot Pursuit: NASA’s Parker Solar Probe Completes 18th Close Approach to the Sun

Bacon (STScI)) NASA's Voyager 1 probe is currently unable to transmit any scientific or systems data back to Earth. The 46-year-old spacecraft is capable of receiving commands, but a problem seems to have

NASA’s Mars Sample Return in jeopardy after US Senate report
News Spaceflight Artist's conception of the vehicles that would participate in a Mars sample return by NASA and the European Space Agency. (Image credit: NASA/JPL-Caltech) NASA's Mars Sample Return mission is facing some tough scrutiny. The Senate Appropriations Committee offered their recommendations on the spending bill for fiscal year 2024, and they do not provide all
Nasa’s new 3d-printed superalloy can handle high temperatures
Multiprincipal-element alloys are an important class of materials due to their mechanical and oxidation-resistant properties. A team of innovators from NASA and The Ohio State University detailed the characteristics of the new alloy, GRX-810, an oxide-dispersion-strengthened NiCoCr-based alloy. GRX-810 uses laser powder bed fusion to disperse nanoscale Y2O3 particles throughout the microstructure without resource-intensive processing
This is the spacesuit NASA’s Artemis astronauts will wear on the Moon
NASA and Axiom Space are finally ready to show what Artemis III astronauts will wear when they walk on the Moon. The two have unveiled a prototype spacesuit that crews will use for moonwalks near the lunar South Pole. As promised, the design is meant to accommodate a wider range of body types. It's also
