NASA’s ISS Google+ Hangout is live right now

A couple of weeks ago, NASA announced that it would be conducting a live Google+ Hangout from the International Space Station today starting at 10:30 am ET. Of course, the space agency is sticking to their promise and have officially started the Hangout, which means you can watch live as astronauts answer all your hankering questions.

iss-earth1-580x3841

Astronauts Kevin Ford, Tom Marshburn, and Chris Hadfield are answering questions from now until approximately 11:30 am ET. The team is answering both pre-recorded questions sent in via YouTube, as well as live questions from social media sites like Facebook, Twitter, and of course Google+. We’ve embedded the live stream below for your viewing pleasure.

The deadline for submitting video questions has already passed, but you can still submit live questions via social media sites using the #askAstro hashtag, but don’t be upset if the astronauts don’t end up getting to your question — we’re sure they have thousands of other questions to pick from.

Overall, it should be an interesting talk with the astronauts, who will mostly discuss what it’s like in space, and what it’s like to feel weightless in zero gravity. Of course, if you follow soon-to-be ISS commander Chris Hadfield on Twitter, he usually provides sneak peeks inside the ISS every once in a while.

Astronomers discover Moon-sized exoplanet called Kepler-37b

Scientists have announced that they have discovered an odd little planet that has set a new record for the smallest alien world ever discovered. According to the scientists, the exoplanet is about the same size as the Earth’s moon. The planet has been dubbed Kepler-37b.

tiny-planet

The scientists involved in the discovery say that this is the first exoplanet ever discovered that is smaller than Mercury. The planet makes an orbit of its parent star every 13 days and has an insanely high surface temperature of about 800°F. This planet was discovered along with two other larger planets orbiting the same parent star.

The parent star is about 215 light years from Earth, it and its planets were discovered using the Kepler space telescope. The two larger planets have been called Kepler-37c and Kepler-37d. The scientists say that 37b is so small finding it was unlikely, but the parent star had some attributes that made the discovery possible.

The attributes that made the discovery of the tiny planet possible included some sunspots on the parent star and the fact that the star is bright relative to its planets. These facts made it easier for Kepler to spot the dimming that takes place when a planet passes in front of its parent star, called the transit. The tiny size of the planet was estimated because the dip in the parent star’s light was only 22 ppm. The scientists say that all three of the planets in orbit around the star are likely uninhabitable and all three are well inside the Earth-sun distance.

Mercury once boasted an ocean of boiling hot magma says researchers

Scientists and researchers all around the world are constantly looking at our universe and trying to learn new details about our solar system and what’s going on beyond our solar system in the universe. Recently researchers from MIT published the results of an experiment that demonstrates that Mercury may have had an ocean of magma on its surface. The experiment demonstrated that Mercury could have had its lava ocean approximately 4,000,000,000 years ago.

During the study, the scientists looked at data gathered by the NASA Messenger probe concerning the composition of Mercury’s surface. During the study, the scientists were interested to find that the surface of Mercury is composed of two massively different rock compositions. The scientists began an investigation to determine what geological process could’ve made the surface be comprised of two such fundamentally different types of rock.

The researchers then use the data from Messenger to reconstruct two different types of rock found on Mercury and then subjected those rocks to different temperatures and pressures allowing them to simulate processes the could’ve occurred on the surface of Mercury. The scientists say that after their experiments they determined that the only process that could have occurred on the surface of Mercury that would’ve caused such radically different types of rock would have been if the planet once had an ocean of magma on its surface.

Timothy Grove, a geologist from MIT, said that the process would’ve occurred billions of years ago because Mercury’s crust is “probably more than 4 billion years old.” Scientists estimate that the magma ocean on the surface of Mercury would’ve existed during the first 10 million years after Mercury’s formation. While using a geological experiment to explain a finding on the surface of the planet is not unheard of, it is rather uncommon in the astronomy world.

Why Does This Image of the Mount Etna Volcano Eruption from Space Look So Weird?

Because Earth can sometimes look like an Impressionist painting from space, NASA added colors to the Mount Etna volcano eruption to separate what from what. The false-color image combines shortwave infrared, near-infrared and green light in the RGB channels. It looks like Earth on acid. More »

NASA’s Kepler telescope spies smallest planet to date, no aliens

NASA's Kepler telescope spots smallest planet to date, no aliens

NASA’s Kepler telescope is permanently on the lookout for celestial objects of interest, and its latest discovery is a small one. A small planet, to be exact — in fact, the smallest its encountered during its search. Kepler-37b is a tad larger than our heavenly dance partner, the Moon, and whizzes round a star much like our Sun, with two larger planets in its system for company. NASA’s issuing back pats all round, as finding Kepler-37b has highlighted “the precision of the Kepler instrument” (although admittedly, the star’s behavior was favorable), and suggests there are many more humble worlds of similar size awaiting our detection. It’s unlikely any aliens call Kepler-37b home: it’s thought to be rocky, with no atmosphere, and hugs its sun in a 13-day orbit cycle, meaning surface temperature is terribly high. Still, an achievement for Kepler, no doubt, but what we really want it to find is a planet home to beings who can explain the plot-line of Prometheus. We’re still a little confused.

Between this and the Arduino, you’d think NASA’s Swamp Works was a hackerspace — though, perhaps in a sense, the research facility kind of is. And really, between the organization’s on-going fascination with the potential of 3D printing and a desire to meet budgetary concerns, we probably shouldn’t have been all too shocked to see a first-gen MakerBot Replicator on a table of the former Apollo-testing facility. The printer wasn’t actually in use during our visit, and the Hazardous Operation tag could probably be taken to be a bit tongue-in-cheek — though, when it comes to space travel, you can never be too careful.

Visualized: Arduino Uno shows up in NASA’s Swamp Works facility

Image

There are certain things you’d expect to encounter on a visit to NASA’s Swamp Works research facility. Walking into the former Apollo testing facility, you’ll almost certainly catch glimpses of martian rovers, soil samples and an assortment of scientific testing devices. But in spite of Arduino’s near ubiquity these days, we’ll admit that we were a bit taken aback when the familiar blue microcontroller made an appearance on a lab desk during our conversation with NASA “lighting guy,” Dr. Eirik Holbert. It seems that NASA, like pretty much everyone else, is experimenting with the hacker-friendly component.

The board was hooked up to a lighting fixture Holbert is working on as part of NASA’s upcoming deep space habitat concept generator. It’s an attempt to bring some sunlit consistency to space exploration, simulating Earth-like lighting patterns to help keep the crew alert and get them ready for sleep in the evenings. So, where does NASA turn when it’s looking to conserve weight and save some taxpayer money in the process? Toward the Arduino Uno, naturally. Holbert assembled a number of off-the-shelf products, including the aforementioned microcontroller and shields from Sparkfun to make a fixture for under $500.

Asked whether we might be seeing an Arduino setup like this on an upcoming mission, Dr. Holbert told us, “I’m all about interchangeability. If they can make something space compatible, I’d be all for it.”

NASA shows Asteroid 2012 DA14 escaping after cheeky Earth buzz

It may look like bad graphics from an 8-bit video game, but you’re actually looking at asteroid 2012 DA14 as it made its Earth-buzzing flyby, courtesy of the Goldstone Solar System Radar. The blurry footage of the roughly 130-foot long space rock was captured as it was moving away from the Earth on February 15, with the 230-foot Deep Space Network antenna capturing shots of it as close as 74,000 miles away.

nasa_asteroid_radar

As you might expect, that doesn’t add up to a huge amount of resolution, even when you’re dealing with a rock bigger than a house. In fact, NASA can manage a resolution of around 13 feet to a pixel, with the captured shots – combined into a video, below – covering a total period of nearly eight hours.

During that time, asteroid 2012 DA14 moved 195,000 miles away from the Earth, and completed roughly one full rotation. Even though the resolution isn’t great, it’s still sufficient for NASA to make some judgements on the asteroid’s size, shape, and rotation, not to mention the condition of its surface, such as roughness and any protruding features.


Meanwhile, knowing an asteroid is there is obviously better than not having a clue of its whereabouts, and so the Deep Space Network antenna works in tandem with the Near-Earth Object Observations Platform, aka “Spaceguard,” to identify what might one day present a collision issue. Happily that was never an issue with DA14, though the asteroid did come so close to the planet as to pass through the gap in-between it and the ring of  geosynchronous weather and communications satellites in orbit.

NASA lost communication with the ISS due to computer problems

NASA has announced that it briefly lost contact with the International Space Station on Tuesday. The ISS was out of contact with ground controllers after some sort of computer problem blocked communications. NASA says that the computer issue lasted just under three hours.

iss-solar

The ISS commander said that the space station and crew was fine during the communications blackout. The communications problem stemmed from a software update that flight controllers in Houston were uploading to the space station’s flight computers. During the upload, the space stations data relay system broke down.

NASA says that the primary computer designed control critical station functions defaulted to a backup computer but the space station was unable to communicate. The space station has to be able to communicate with the NASA Tracking and Data Relay satellites to communicate with ground controllers. NASA reports that flight controllers in Houston were able to communicate with the ISS as the space station flew over Russian ground control stations.

Ground controllers told the ISS crew at the time to connect to a backup computer and begin restoring communications. Apparently, all functions onboard the ISS are normal at this time. There are currently six astronauts aboard the space station including two Americans, three Russians, and a Canadian.

Russian meteor had nothing to do with 2012 DA14 asteroid flyby

The scientific community is still following the meteor that exploded over Russia last Friday closely. The meteor exploded over Chelyabinsk, Russia at approximately 7:20 PM PST. The explosion had enough force to blow the Windows out of hundreds of buildings and cause injury to an estimated 1200 people, mostly from falling glass.

meteor-impact

The fireball seen in the Russian skies on Friday happen to be close in time to asteroid 2012 DA14. NASA has announced that the Russian meteor was unrelated to 2012 DA14. NASA has offered some revised size estimates for the meteor that entered the atmosphere over Russia.

The original size estimates for the meteor put it at 49 feet in diameter and NASA has revised its size estimate putting the meteorite at 55 feet in diameter. NASA also increased the estimated mass of the meteorite from 7,000 tons to 10,000 tons. NASA scientists estimate that the energy released by the object was equivalent to nearly 500 kilotons of explosives on.

The new information about the meteorite was collected by five additional infrasound stations located around the world. The first recording of the event was captured in Alaska, over 6500 km from Chelyabinsk, Russia. NASA also says that with an object of this size, a large number of meteorites would be expected to reach the surface of the planet and the scientists believe in this case, there were probably some large fragments. Scientists also say that the duration of the event means that the meteor made a very shallow entry into the Earth’s atmosphere.
