Echoes of Chelyabinsk: Another Fireball Explodes Over Russia

Why does Russia seem to get so many bright meteors? Well at 6.6 million square miles it’s by far the largest country in the world plus, with dashboard-mounted cameras being so commonplace (partly to help combat insurance fraud) statistically it just makes sense that Russians would end up seeing more meteors, and then be able to share the experience with the rest of the world!

This is exactly what happened early this morning, April 19 (local time), when a bright fireball flashed in the skies over Murmansk, located on the Kola Peninsula in northwest Russia near the border of Finland. Luckily not nearly as large or powerful as the Chelyabinsk meteor event from February 2013, no sound or air blast from this fireball has been reported and nobody was injured. Details on the object aren’t yet known… it could be a meteor (most likely) or it could be re-entering space debris. The video above, some of which was captured by Alexandr Nesterov from his dashcam, shows the object dramatically lighting up the early morning sky.

One Russian astronomer suggests this bolide may have been part of the debris that results in the Lyrid meteor shower, which peaks on April 22-23. (Source: NBC)

Bill Nye on Taking Astronomy with Carl Sagan

“This is how we know nature. It is the best idea humans have ever come up with.”
– Bill Nye, Science Guy and CEO of The Planetary Society

In this latest video from NOVA’s Secret Life of Scientists and Engineers, science guy Bill Nye talks about the incredible influence that Carl Sagan had on his life, from attending his lectures on astronomy at Cornell University to eventually becoming CEO of The Planetary Society, which was co-founded by Sagan in 1980.

“I took astronomy from Carl Sagan.” Now there’s a statement that’ll get people’s attention. (It got mine, anyway.)

Morpheus Flies Higher and Farther Than Ever

Engineers prepare the Morpheus craft for its FF9 test flight on March 11, 2014 (NASA)

)
NASA’s Project Morpheus nailed it again today with yet another successful free flight of their prototype lander, soaring higher, faster, and farther than ever before! Go Morpheus!

The FF9 test, which occurred at 3:41 p.m. EDT at Kennedy Space Center, saw the 2,300-lb (1000-kg) Morpheus craft rise to a height of 580 feet (177 meters) and travel 837 feet (255 m) downrange at 30 mph (48 km/h). After the 85-second flight the craft set down almost exactly on target — only about a foot (.3 m) off.

During today’s test flight the oxygen-and-methane-propelled Morpheus could have cleared the Washington Monument.

The next step is to integrate the Autonomous Landing and Hazard Avoidance Technology (ALHAT) sensors, which allow the craft to identify dangerous terrain and determine the best route to a safe landing — all by itself. This capability will be invaluable for future landings on unexplored surfaces on the Moon and Mars.

“It’s never been done,” said Dr. Jon Olansen, project manager of the Morpheus Project, in 2012. “We’ve never landed of the moon or Mars with real-time hazard detection and avoidance. Most of the Mars missions use air bags. They go where they go, they roll them and they stop… whatever comes, comes.”

Playing Marbles With The Planets

We’ve all seen charts showing the relative sizes of planets and moons compared to each other, which are cool to look at but don’t really give a sense of the comparative masses of the various worlds in our Solar System. It’s one thing to say the Earth is four times larger than the Moon, it’s entirely another to realize it’s 87 times more massive!

That’s where this new animation from astrophysicist Rhys Taylor comes in nicely.

Watch Saturn Slip Behind the Moon

Occultation of Saturn on Feb. 22, 2014 by Colin Legg

Or, more accurately, watch the Moon pass in front of Saturn. Either way you get the same result: a beautiful video of planetary motion in action!

On the morning of Saturday, Feb. 22, the Moon drifted in front of the planet Saturn from the point of view of certain locations on Earth. Luckily one of those locations was Perth, Australia, where astrophotographer Colin Legg happens to be, and thus we all get to enjoy the fantastic results of his photographic and astronomical acumen.

Check out the video below:

The occultation — as such events are called whenever one celestial object passes in front of, or “hides,” another (the root of the word means “to conceal”) — may make it look like a tiny Saturn is getting absorbed by a giant Moon. But (obviously) they are separated by a vast distance: at the time of the occultation, 9.658 AU, or about 1,444,816,000 kilometers (897.7 million miles).

These sort of events will become a bit more common as the Moon is “headed towards a ‘shallow’ year in 2015 relative to the ecliptic; it will then begin to slowly open back up and ride high around 2025,” according to a recent Universe Today article by David Dickinson.

For those of you interested, Colin lists his equipment as a Celestron C8, f/10, prime focus. His camera is a Canon 5D2, running Magic Lantern RAW video firmware in 3x crop mode @ 1880 x 1056 resolution. Footage was taken at 1/60 sec exposure, ISO 200, 10 fps.

The Joy of Discovery, Featuring Bill Nye

“We are, you and I, at least one of the ways that the Universe knows itself.” – Bill Nye

Did you manage to (or choose to) watch the much-anticipated debate between Science Guy Bill Nye and Ken Ham on the “merits” of Creationism on Feb. 4? While clearly nothing more than a publicity event cooked up by Ham to fund his Creation Museum in Kentucky (yes, I’m afraid that’s actually a thing here in America) Nye felt it to be in his — as well as the country’s — best interest to stand up and defend science and its methods in the face of unapologetic fundamentalist denial.

The video above, just released by John D. Boswell — aka melodysheep, creator of the excellent Symphony of Science series — takes some of Bill’s statements during the debate and puts them to music and images of our fascinating world.

Wake Up, Rosetta!

It’s being called “the most important alarm clock in the Solar System” — this Monday, January 20, at 10:00 GMT (which is 5:00 a.m. for U.S. East Coasters like me) the wake-up call will ring on ESA’s Rosetta spacecraft, bringing it out of hibernation after over two and a half years in preparation of its upcoming and highly-anticipated rendezvous with a comet.

The wake-up will incite the warming of Rosetta’s star trackers, which allow it to determine its orientation in space. Six hours later its thrusters will fire to stop its slow rotation and ensure that its solar arrays are receiving the right amount of sunlight. Using its thawed-out star trackers Rosetta will aim its transmitter towards Earth and, from 500 million miles (807 million km) away, will send a thumbs-up signal that everything is OK and it’s time to get back to work.

From that distance the transmission will take 45 minutes to reach us. Rosetta’s first signal is expected between 17:30 – 18:30 GMT (12:30 – 1:30 p.m. ET). Once we’re assured all is well, Rosetta has a very exciting year ahead!

After nearly a decade of soaring through the inner solar system, flying past Mars and Earth several times and even briefly visiting a couple of asteroids (2867 Steins on September 5, 2008 and 21 Lutetia on July 10, 2010) Rosetta is finally entering the home stretch of its mission to orbit the 4-km-wide comet 67P/Churyumov-Gerasimenko.

Once Rosetta enters orbit around the comet — the first time a spacecraft has ever done so — it will map its surface and, three months later in November, deploy the 220-lb (100-kg) Philae lander that will intimately investigate the surface of the nucleus using a suite of advanced science instruments. (Watch a video here of how all this will happen… using Legos!)

With Philae firmly attached to the comet, Rosetta will follow it around the Sun as it makes its closest pass in August 2015 and then heads back out towards the orbit of Jupiter. Rosetta will provide the most detailed observations ever of a comet’s composition and dramatic evolution as it encounters the heat and energy of our home star.

Of course, before all this can happen Rosetta first has to… WAKE UP! It entered hibernation in July 2011 and has remained silent in a slow spin ever since, with only its computer and some heaters kept running. Waking up from a 31-month nap can’t be easy, so ESA is inviting people around the world to help Wake Up Rosetta (and possibly even win a trip to Germany for the landing in November) by sharing their short movies of how best to awaken a sleeping spacecraft and sharing them to the contest page on Facebook or to Twitter, Vine, or Instagram with the #WakeUpRosetta hashtag.

See more about the contest below:

Video submissions to the Wake Up Rosetta video contest will be accepted until 17:30 GMT on Monday so if you haven’t already, get your cameras out and your imaginations going… this spacecraft isn’t going to wake itself! (Well, actually it kinda is but you can still show off your creativity!)

And even if you don’t send in a video, you can watch the live feed of Monday’s events from ESA starting at 09:15 GMT (4:15 a.m. ET) here and here. (Also follow @ESA_Rosetta on Twitter — currently it’s “still sleeping.”)

Want to find out where Rosetta is right now? Check out this cool interactive map from Daniel Scuka, Senior Editor of Spacecraft Operations at ESOC.

Rosetta launched on March 2, 2004 by an Ariane-5 G+ from Europe’s spaceport in Kourou, French Guiana. Read more on the mission page and the Rosetta blog here.

UPDATE Jan. 20: Rosetta has awoken! This afternoon at 18:18 UTC, after 48 minutes of increasingly tense anticipation, a signal from the spacecraft was received by both NASA’s Deep Space Network in Goldstone, CA and the ground station in Canberra, Australia. Rosetta is up and running and so far seems to be in good condition — Go Rosetta and Philae! Read the full story here.

Is NASA Dead? Not Even Close.

If you’re a frequent reader of Universe Today you know that, despite the end of the Shuttle program and the constant battle for a piece of the federal budget, NASA has a lot on their plate for future space exploration missions. But there are still a lot of people among the general public who think that the U.S. space administration is “dead,” or, at the very least, in the process of dying. Which is unfortunate because there’s actually a lot going on, both in space and in development on the ground.

The video above, released Monday by Johnson Space Center, shows highlights from 2013 as well as some of the many things NASA has in progress. As anyone can see, rumors of its death have been greatly exaggerated! (By whom I’m still not quite sure.)

Visit the Johnson Space Center site for more information and updates on current and future missions.

This Time-Lapse ISS Video Isn’t Just Another Time-Lapse ISS Video

It’s actually remarkably beautiful, and well worth two minutes of your time.*

Assembled from actual photographs taken by astronauts aboard the Space Station, many of them by Don Pettit during Expedition 31 (Don took a lot of photos) this timelapse “The World Outside My Window” by David Peterson ramps up the artistic value by featuring super-duper high definition, smoothed frame transitions and a musical score by “Two Steps From Hell.” (Don’t worry, that sounds scarier than it is.) Even if you’ve seen some of these clips before, they’re worth another go.

After all, there’s no good reason not to be reminded of how beautiful our planet is from space. Enjoy!

*It’s actually two minutes and twenty-eight seconds but I don’t think you’ll mind.

NASA’s STEREO Spacecraft Spots Comets ISON and Encke

Comet ISON entered the STEREO scene with Encke on Nov. 21 (Credit: Karl Battams/NASA/STEREO/CIOC)

As comets ISON and Encke continue toward their respective rendezvous with the Sun, they have now both been captured on camera by NASA’s solar-observing STEREO spacecraft. The image above, taken on Nov. 21 (UT) with STEREO-A’s high-resolution HI-1 camera, shows ISON as it enters the field of view from the left. Encke is at center, while the planets Mercury and Earth (labeled) are bright enough to cause vertical disruptions in the imaging sensors. (The Sun is off frame to the right.)

As cool as this image is, it gets even better: there’s a video version. Check it out below:

It’s fascinating to watch how the solar wind shapes and affects the tail of comet Encke… as ISON moves further into view, I’m sure we’ll see similar disruptions in its tail as well. (And look what STEREO-A saw happen to Encke’s tail back in 2007!)

Encke reached the perihelion of its 3.3-year-long orbit on Nov. 21; newcomer ISON will arrive at its on Nov. 28. While it seems to be holding together quite well in these STEREO images, what happens when it comes within 730,000 miles of the Sun next week is still anybody’s guess.
