This Video Lets You Fly Over The Surface Of Mars
To celebrate 10 years of images from the European Space Agency's Mars Express orbiter, the German Aerospace Center has compiled a video that gives sweeping digital views of the planet's landscape.
What's the Latest Development?
In the summer of 2003, the European Space Agency (ESA) launched a mission to explore the surface of Mars from orbit as well as on the ground. While the rover, Beagle 2, stopped communicating shortly after leaving the orbiter, that orbiter, Mars Express, has spent the last 10 years taking pictures of the entire planet. To celebrate that milestone, the German Aerospace Center (DLR) has released a video compilation of images that gives the viewer the sensation of flying over canyons, craters, and mountains.
What's the Big Idea?
DLR is also responsible for the camera that's producing the images: The Mars Express High Resolution Stereo Camera "consists of nine individual image sensors, [each of which] is used to sweep the surface from a different observational angle." This results in 3D models of the surface that are extremely detailed and accurate. Largely because of this data, the ESA has extended the orbiter's mission five times, with the current end date scheduled for sometime in 2014.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Former president of the ACLU Nadine Strossen discusses whether our society should always defend free speech rights, even for groups who would oppose such rights.
- Former ACLU president Nadine Strossen understands that protecting free speech rights isn't always a straightforward proposition.
- In this video, Strossen describes the reasoning behind why the ACLU defended the free speech rights of neo-Nazis in Skokie, Illinois, 1977.
- The opinions expressed in this video do not necessarily reflect the views of the Charles Koch Foundation, which encourages the expression of diverse viewpoints within a culture of civil discourse and mutual respect.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
- In some fundamental ways, humans haven't changed all that much since the days when we were sitting around communal fires, telling tales.
- Although we don't always recognize them as such, stories, symbols, and rituals still have tremendous, primal power to move us and shape our lives.
- This is no less true in the workplace than it is in our personal lives.
