Farewell Cassini

Image
One of Saturn's moons above its rings against star-lit space. If you like science and dream of exploring the stars or going into space one day, then you are probably aware of the Cassini mission. The probe recently took its last photo just as it entered the Venus atmosphere, but before the camera faded to black it took many beautiful photos. If you are not science buff, " Cassini-Huygens is one of the most ambitious missions NASA ever launched into space. Loaded with an array of powerful instruments and cameras, the spacecraft is capable of taking accurate measurements and detailed images in a variety of atmospheric conditions and light spectra." Cassini reached Saturn in July 2004 and has been dubbed one of the most successful of NASA's many missions. It's " scripted death dive " occurred on September 15, 2017. What are some of the missions biggest discoveries? One of its moons, Enceladus, shows evidence of water-based ice and a subsurface ...

Your tax dollars at work - Thanks NASA!

NASA is a great program that produces technical wonders including freeze dried food (yuck) and cameras (YAY - including the one in your phone. In the past few years we've been receiving photos from various space projects and some of them are just so stunning they look fake. But these are fake news photos! This picture of the moon in front of the sun was taken from NASA's Deep Space Climate Observatory satellite that sits a million miles away from Earth. "In 2015, it looked back at its home planet and captured a series of images showing what rock band Pink Floyd refers to as the 'dark side' of the moon (more aptly known as the 'far side' of the moon) as it passed between the camera and Earth. It's an almost startling perspective from a satellite that has a primary mission of monitoring solar winds." Here's one reminiscent of All Hallows Eve- the sun looks like an evil Jack-O-Lantern. This picture was taken by the Solar Dynamics Obser...

Wanna Talk Alien? Need to Speak Visuals!

Reading visuals - even NASA does it. Archaeology, Anthropology and Interstellar Communication is a recent tile released by NASA, edited by Douglas A. Vakoch. Vakoch believes that when ET tries to communicate with us it will not be through sound but via images. All the stuff you had to learn about reading images is going to come in handy. "Vision and the use of images would appear to be at least plausible. Although spectral details cannot be considered universal, the physical arrangement of objects on a habitable planet’s surface will be shaped in part by gravity (the notion of a horizon might well be universal) and thus multispectral images might plausibly be considered worthwhile for messages." So what kind of images do we send out? One message contained the binary numbers one through ten, equations of basic chemistry, human bio chemistry, and DNA.  Another contained a drawing of what we look like, pulsar directives, and a schematic of our solar system. In othe...

A Rocky Football Field Just Missed Earth

Asteroid DA14 just streaked by the earth on February 15 - half the size of a football field. The day before a meteor hit Russia causing loads of damage and panic, and according to the experts these two events are unrelated. Want to watch NASA track a DA14? Here's the footage: Video streaming by Ustream Here's something to think about. An asteroid the size of DA14 hit Earth on June 30, 1908 and levelled 820 square miles. Accourding to NASA when DA14 makes its closest approach to Earth at approximately 11:25 a.m. PST (2:25 p.m. EST / 19:25 UTC), the asteroid will be about 17,150 miles (27,600 kilometers) above Earth’s surface. The commentary will be available via NASA TV and streamed live online at: http://www.nasa.gov/ntv and http://www.ustream.tv/nasajpl2 Many objects in outer space are discovered and tracked by astronimacal enthusiasts, people just like you and me. Should we have an agency that watches for these kinds killer asteroids?
