It is not easy to observe Jupiter’s moons as more than points of light with Juno, because Juno will never get very close to any of the moons, but as its orbit shifts there will be opportunities to collect data on some of the moons.
NASA announced this afternoon that Juno passed through its first perijove since entering orbit successfully, with science instruments operating all the way. This is a huge relief, given all the unknowns about the effects of Jupiter's nasty radiation environment on its brand-new orbiter.
What began as a tantalizing rumor has just become an astonishing fact. Today a group of thirty-one scientists announced the discovery of a terrestrial exoplanet orbiting Proxima Centauri. The discovery of this planet, Proxima Centauri b, is a huge breakthrough not just for astronomers but for all of us. Here’s why.
Whenever I share images from Curiosity, among the most common questions I’m asked is “what is the scale of this image?” With help from imaging enthusiast Seán Doran, I can answer that question for some of the Murray buttes.
Our Horizon Goal series on NASA's human spaceflight program continues with part 3, in which newly elected President Barack Obama and his transition team search for a NASA administrator, commission a review of the Constellation program and decide whether to extend the life of the ISS.
Launch day is coming for NASA's next interplanetary explorer! OSIRIS-REx is on schedule for launch on September 8, 2016 at 19:05 EDT (16:05 PDT, 23:05 UTC) from Cape Canaveral Air Force Station. OSIRIS-REx is the first NASA planetary launch since MAVEN in 2013, and will be the last until InSight in 2018.
Martian gullies were in the spotlight last week thanks to a NASA press release stating they were "likely not formed by liquid water" based on spectral results. But how does this stack up against their morphology?
Curiosity has now covered most of the flat ground that lay between the Naukluft plateau and the Murray buttes. The mission took only 11 days to complete drilling work at Marimba, despite a recurrence of a problematic short in the drill. The rover is ready to drive in among the buttes, shooting spectacular photos along the way.
NASA’s next big “flagship” astronomy mission, following the ambitious James Webb Space Telescope due to be launched in 2018, is currently known as the Wide Field Infrared Survey Telescope (WFIRST)—but it's had a slew of different names.
As it approached Jupiter from June 12 to 29, JunoCam captured an animation of the major moons orbiting the planet. The mission released a processed version of the animation on the day of orbit insertion, but took a few weeks to release the raw image data. I've prepared a page hosting all the raw data, and share a few processed versions.
On August 25th, 2016, the U.S. National Park Service is celebrating its Centennial. That’s 100 years of protecting the lands and the night skies so that people from around the world and all walks of life can come and see the stars!
We know, as well as you do, that if we want to see a great future – one where humans explore, understand, and benefit from space – we need to invest right now in the people who will be leading the way. To empower the world’s youth, we need to educate them. And to educate them, we need to inspire them.
