So did you get out and Wave at Saturn on The Day the Earth Smiled? If you did (and even if you didn’t) here’s how you — and everyone else on Earth — looked to the Cassini spacecraft in orbit around Saturn, 898.4 million miles away.* As Carl Sagan famously said, “That’s here, that’s home,…

This Day in Space History: One Small Step
Note: Reposted/updated article from 2012. “That’s one small step for a man… one giant leap for mankind.” I’m not sure what else need be said about the significance of what happened on this day in 1969, 44 years ago… it was a shining moment in human history, and will be — should be — remembered…
Ring Shadows Surround Saturn’s South
Cassini gets a great look at Saturn’s southern half in this color-composite, assembled from raw images acquired on July 13, 2013. Click for a larger view in my Flickr stream (the original raw images were only 1024 px, so it’s still a little grainy.) I adjusted the channel histograms quite a bit to achieve a…
New Horizons’ First Look at Pluto’s Big Moon
The two bright clusters of pixels in the image above might not seem like much of a big deal, but they are… those two blocky blobs are the dwarf planet Pluto and its largest moon, Charon, as seen by the rapidly-approaching New Horizons spacecraft, destined for its ultimate close encounter in July 2015! This represents…
NASA Announces Goals for Next Mars Rover
“If it ain’t broke, don’t fix it” — that seems to be the idea behind the designs for NASA’s next Mars mission, which will put yet another rover on the Red Planet in 2020. Drawing on the developments from previous rovers — Spirit, Opportunity, and especially Curiosity — the next robotic explorer will feature a…
On July 19, Smile and Wave at Saturn
…because Cassini will be watching — and taking pictures! In three weeks, on Friday, July 19, the Cassini spacecraft will be taking pictures from orbit around Saturn, capturing the ringed planet in eclipse against the Sun. This will not only provide fantastic views of the planet’s rings and atmosphere, but will also include another treat:…
Supermoon Returns!
If you haven’t heard, tomorrow (June 23) will bring the closest full Moon of the year, which will make it appear big and bright in the night sky — a so-called “Supermoon.” But what does this really mean and how does it happen? Dr. Michelle Thaller of NASA’s Goddard Space Flight Center explains: While a…
Want to see a BILLION-pixel view of Mars from Curiosity?
Well, here you go. Don’t say I never gave you nothin’. 😉 Actually this is a NASA-produced image made of 850 frames taken by Curiosity’s MastCam, showing the view from the rover as of late October/early November 2012. Mount Sharp (Aeolis Mons) rises in the distance, and the mountainous rim of Gale Crater can be…
“Like L.A. Smog on Steroids” – Cassini Scientists Pick Apart Titan’s Haze
Scientists working with data from NASA’s Cassini mission have confirmed the presence of a population of complex hydrocarbons in the upper atmosphere of Saturn’s largest moon, Titan, that later evolve into the components that give the moon a distinctive orange-brown haze. The presence of these complex, ringed hydrocarbons, known as polycyclic aromatic hydrocarbons (PAHs), explains…
Road Trip! Curiosity Prepares for Some Long-Distance Driving
It’s time for Curiosity to get into high gear! NASA’s Mars Science Laboratory mission is approaching its biggest turning point since landing its rover, Curiosity, inside Mars’ Gale Crater last summer. Curiosity is finishing investigations in an area smaller than a football field where it has been working for six months, and it will soon…
Dione to Join the List of Moons with Underground Oceans?
Earth may display its seas on its surface for all the Universe to see, but further out in the Solar System liquid oceans are kept discreetly under wraps, hidden beneath cratered surfaces of ice and rock. And while Saturn’s moon Enceladus sprays its salty subsurface ocean out into space, other moons are less ostentatious —…
Win a DVD of NOVA’s Excellent “Earth From Space”
Earth… our home planet, a brilliant “blue marble” tirelessly turning through space on an endless journey around the Sun and across the galaxy. Basically a ball of molten rock and metal, its relatively thin crust is mostly covered by a sea of liquid water as well as wrapped in a sea of air… and it’s…
