MTM's Epiphany epiphany - or the Wenlock Edge Moment

MTM’s Epiphany epiphany – or the Wenlock Edge Moment

I love the New Year. Christmas is over and I am home free. You know how, if you let a bee out of the window it flies miles up into the air as if it’s delighted to have escaped.* Well, yeh, I feel like that. * Obviously, it isn’t delighted to have escaped. It’s a bee. It’s actually going up there to orientate itself and find its way back to its hive but there’s no harm in a little Victorian-style…

In 2013, researchers published a shape model of asteroid Bennu based on years of observations from Puerto Rico’s Arecibo Observatory. Their model depicted a rough diamond shape. Five years later, the OSIRIS-REx spacecraft has reached the asteroid, and data obtained from spacecraft’s cameras corroborate those ground-based telescopic observations of Bennu. 

The original model closely predicted the asteroid’s actual shape, with Bennu’s diameter, rotation rate, inclination and overall shape presented almost exactly as projected! This video shows the new shape model created using data from OSIRIS-REx’s approach to the asteroid.

One outlier from the predicted shape model is the size of the large boulder near Bennu’s south pole. The ground-based shape model calculated it to be at least 33 feet (10 meters) in height. Preliminary calculations show that the boulder is closer to 164 feet (50 meters) in height, with a width of approximately 180 feet (55 meters).

Also during the approach phase, OSIRIS-REx revealed water locked inside the clays that make up Bennu. The presence of hydrated minerals across the asteroid confirms that Bennu, a remnant from early in the formation of the solar system, is an excellent specimen for the OSIRIS-REx mission to study. Get all the details about this discovery HERE.

The Dark Lord’s Handbook, by Paul Dale. The Dark Lord’s Handbook, Part 1 To start with, let’s do the the blurb: To become a Dark Lord is no easy thing. The simple ambition to hold dominion over the world and bend all to your will sounds straightforward but it’s not. There’s armies to raise, fortresses to build, heroes to defeat, battles to be fought, hours of endless soliloquy in front of the…

We’re using our unique vantage point in space to provide observations and data of Hurricane Irma and other tropical storms. Hurricanes Irma and Jose are seen here in a 12-hour long infrared loop. Scientists monitor storms in infrared to closely monitor clouds and storm intensity. We continue to provide satellite imagery for these storms, tracking its trajectory, force and precipitation to inform forecasters at the National Hurricane Center.

As these storms continue their westward drive in the coming days, they will be passing over waters that are warmer than 30 degrees Celsius (86 degrees Fahrenheit)—hot enough to sustain a category 5 storm. Warm oceans, along with low wind shear, are two key ingredients that fuel and sustain hurricanes. Get the latest imagery and data from us at www.nasa.gov/hurricane For information on making preparations for Hurricanes, visit the FEMA website at: ready.gov/hurricanes. Credit: NASA-SPoRT/NOAA
