Seeds in the Cosmic Wind: Carl Sagan on Space Exploration

Got the Monday back-to-work blues? Upset by bad news headlines? Concerned about a potential future President Trump? Take a couple of minutes and watch this.

This video, published by The Royal Institution on YouTube in Dec. 2015 and shared again on Twitter today, features an adorable animation about spaceflight with narration taken from a lecture given by Carl Sagan in 1977.

At that time it had been five years since humans had last walked on the Moon, the first Space Shuttle flight was still three and a half years away and the Voyagers had only just passed the orbit of Mars. But Sagan’s confidence and enthusiasm about the future of space exploration and human spaceflight is as inspirational now as it was then…let us continue to remember his words and pass along his message to each new generation that looks up and wonders “what’s out there” and, more importantly, “can I go?”

“Artifacts from Earth are spinning out into the cosmos. I believe the time will come when most human cultures will be engaged in an activity you might describe as a dandelion going to seed.”
— Carl Sagan, 1977

Did NASA Purposely Cut Space Station Footage of a UFO?

A truly “unidentified” object on ISS live feed on July 9, 2016…WHAT COULD IT BE?

Various news outlets today have run with a story about a supposed UFO spotted on live video streamed from the International Space Station, in which a bright object is visible “descending” into Earth’s atmosphere. The video* was shared on YouTube by a self-proclaimed UFO hunter—which basically means someone who stares at ISS feeds on their computers until their eyes melt and any speck of anything seen moving is instantly circled, copied into a slow-mo edited version, and overlaid with ominous music and/or bold text highlights claiming alien visitation and government cover-ups. (Views ensue.)

To help this particular spotting along is the fact that the feed cut out just as the object nears the edge of the atmosphere. Assured proof of a galactic-scale conspiracy by NASA and the NWO, right???

Please. Here’s my two-and-a-half cents:

Watch Juno’s Arrival at Majestic Jupiter, Moons and All

We are the stewards of over 400 years of scientific exploration of our Solar System, which it could be said began in earnest when Galileo Galilei first observed the motions of Jupiter’s moons in his homemade telescope in 1610. Over the centuries our knowledge—and our curiosity—about the seemingly endless variety of worlds in the Solar System has grown in leaps and bounds since Galileo’s first peeks at Jupiter, with increasingly more powerful telescopes both on Earth and in space and eventually even machines sent to join the planets in orbit around the Sun.

Last night NASA’s Juno spacecraft became humanity’s most recent emissary to the Solar System’s biggest planet, successfully performing the rocket burns needed to enter orbit around Jupiter—the first spacecraft to do so in 13 years. Amongst much excitement and deserved congratulations of the mission team, the video above was released showing Juno’s view as it approached the enormous planet the week before arrival after five years and 1.7 billion miles of travel. It’s dramatic and impressive and beautiful…just as it should be, considering the scope and achievement of the mission and the information that will soon be returned. Congratulations Juno!

“With Juno, we will investigate the unknowns of Jupiter’s massive radiation belts to delve deep into not only the planet’s interior, but into how Jupiter was born and how our entire solar system evolved.”
— NASA Administrator Charles Bolden

Death in Space

Here’s a bit of fun for you: an animated short of ways one could meet one’s end on a space adventure, by professional animator and illustrator Tom Lucas.

Obviously this is more science-fiction than science fact, what with the hungry aliens and all, but you still wouldn’t want to smash yourself in the faceplate with a chunk of asteroid. (Not without some Duct Tape handy, that is.) The timing is great, and I’ll admit to actual LOLs at the end.

Find more of Tom’s work here, including the equally-spacy short “Botanical Nightmare!” (Perhaps Tom should be getting a NASA contract for outreach videos!)

Ride Shotgun With John Young During His Apollo 16 Grand Prix

Take a ride across the Moon with Apollo 16 commander John Young in this video, a stabilized version of NASA 16mm film footage captured during the first EVA of the mission on April 21, 1972. In what’s called the “lunar Grand Prix” Young pilots the Lunar Roving Vehicle, or LRV, across the dusty terrain of the Descartes highlands, the vehicle’s metal-mesh wheels kicking up plumes of regolith in the near-vacuum and 1/6th Earth gravity environment of the Moon.

If it looks like Young is just having a “grand” time, I’m sure he is—but he wasn’t just hot-rodding. Part of the mission was to evaluate the performance of the LRV with hard turn maneuvers and sudden stops.

Built for NASA by Boeing, the LRVs were stored in a folded position belowdecks on the descent stage of the Landing Modules during the Apollo 15, 16, and 17 missions. They allowed astronauts to cover a much wider area, carry more equipment, and collect more samples while exploring the lunar surface than they could on foot—er, boot. During Apollo 16 John Young and Charlie Duke drive a total of 16.6 miles (26.7 km) during over 20 hours of EVAs. Learn more about the Apollo LRVs here.

The Scale of the Solar System With a Soccer Ball, a Drone, Pin Heads, and Planet Nine

I love models that demonstrate the incredible size and space of the Solar System, very much so because many illustrations and diagrams fail to portray it accurately (and for very good reason…it’s enormous.) The most recent is shown here, enthusiastically created and narrated by former NASA engineer Mark Rober. This particular demonstration is unique in that it’s the only one (that I’ve seen so far) that includes the newest possible-planet in the Solar System, “Planet Nine,” a Neptune-mass world that may orbit the Sun up to four times farther away than Pluto. Check it out above, and you can find some other cool scale models of the Solar System I’ve encountered previously below.

(And remember kids, space is really, really, really BIG.)
