Video: Falling to Earth aboard NASA's Orion spacecraft

A NASA video lets you virtually peer out the window of the Orion spacecraft as it plummets to Earth at speeds up to 20,000 mph.

As you watch, you will see what an astronaut might see if she was ensconced in the capsule after traveling 3,600 miles from Earth.

The video was shot on Dec. 5, during an unmanned test flight that took the spacecraft around the planet twice. The flight was recorded by three video cameras positioned at the side and back windows of the spacecraft's crew module.

This particular video features the last 10 minutes of Orion's 4.5-hour journey to space. It begins just as the spacecraft reenters the Earth's atmosphere. The video ends when Orion lands with a splash in the Pacific Ocean off Baja California.

About 26 seconds into the video there is a dazzling light show in shades of white, yellow, lavender and magenta. The colors are caused by super-heated gas, or plasma, that gets created by the friction between the speeding spacecraft and the gases on the outer edge of our planet. The different colors are caused by increases and decreases in the temperature.

On this test flight, the plasma around the spacecraft got up to 4,000 degrees Fahrenheit. An astronaut inside the capsule might notice the temperature start to climb a bit, but powerful heat shields on the outside of the spacecraft keep cabin temperatures from getting any higher than about 80 degrees Fahrenheit, said Brandi Dean, a NASA spokeswoman.

If the spacecraft were returning to Earth from Mars, however, it would be moving even faster, causing the gas around it to get up to 8,000 degrees Fahrenheit or more.

"There would be some modifications to the current heat shield, but Orion was designed with future deep-space missions in mind," Dean said.

After the light show is over (at about 2:28 into the video) there is a peaceful interlude when nothing much happens. You can see the curvature of the blue Earth meeting the dark black of space as the spacecraft glides across the planet. If this is boring to you, or you don't have much time, you can skip to 5:28, when the first of a series of parachutes start to deploy. The parachutes are attached to the heat shield, which detaches from the spacecraft before landing.

At 5:37, the drogue parachutes deploy. They look like daisies. At 6:34 into the video, these are cut away, and the main parachutes take over. They look like peppermint candies. In the last seconds of the video, you can see the spacecraft landing successfully in the ocean.

NASA's Black Hole X-Ray Hunter Could Solve Solar Mystery

Whats the sun got in common with distant black holes? Well, at first glance, not a lot. But as this psychedelic solar portrait shows, there is one trait that the sun and black holes do have in common the emission of high-energy X-rays.

Now NASAs Nuclear Spectroscopic Telescope Array, or NuSTAR, has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.

GALLERY: NuSTAR Probes a Spinning Black Hole

Long before NuSTAR was even launched in 2012, solar physicist David Smith, of the University of California, Santa Cruz, approached the NASA NuSTAR mission team to request that the space telescope spend some of its observing time looking toward our nearest star.

Shifting focus from the high-energy X-rays generated by supermassive black holes in the centers of galaxies millions of light-years away to the sun may seem strange, but only NuSTAR has the capability of sensing the faint high-energy X-ray flashes generated by small-scale solar flares known as nanoflares deep inside the suns atmosphere, or corona.

At first I thought the whole idea was crazy, said NuSTAR principal investigator Fiona Harrison of the California Institute of Technology in Pasadena, Calif. Why would we have the most sensitive high energy X-ray telescope ever built, designed to peer deep into the universe, look at something in our own back yard?

ANALYSIS: Monster Waves Behind Suns Coronal Heating Mystery?

Staring at the sun is as an unhealthy proposition for space telescopes as it is for the human eye. NASAs Chandra X-ray space telescope, for example, would be blinded if it turned its gaze toward the sun as our nearest star generates a broad spectrum of lower-energy X-rays. But NuSTAR is unique in that it only detects the highest energy X-rays (and doesn't see the low-energy X-rays Chandra is sensitive to) that are generated by powerful relativistic processes surrounding black holes.

And it is high-energy X-rays, which the sun very weakly radiates, that Smith is interested in. But why?

Solar physicists and space weather forecasters have been puzzled for decades as to why the suns corona is so hot. On comparison with the suns surface the photosphere which has a temperature of a few thousand degrees Fahrenheit, the corona is (on average) 1.8 million degrees Fahrenheit (1 million Kelvin). That doesnt make sense in our everyday experience; it would be like the air surrounding a light bulb being hotter than the bulbs glass, a situation that completely violates basic thermodynamic laws normally it gets cooler the further you step away from a heat source, not hotter!

Local Vets Using Nanotechnology To Help Pets Healing

PITTSBURGH (KDKA) Modern medicine is evolving quickly.

Now, with the introduction of bioengineering, doctors can have tissue made for their patients and veterinarians are having great success using nanotechnology in our pets.

Dr. Jed Johnson has a PhD in engineering and his firm engineers body tissue.

The part that I focus on is tissue engineering, where we are basically focusing and building or engineering new tissue for the body, Dr. Johnson said.

Their nanotechnology is an integral part of regenerative medicine.

Weve all seen regeneration. Weve all had cuts on our hands, right? And those cuts heal. So, our body is capable of healing, but we have to provide the right environment, Dr. Johnson said.

Enter nanofibers.

It takes a hundred of the microscopic fibers laid side-by-side to be as wide as a human hair.

Weave them together, and they provide a framework for healing.

Cells and tissue cant move across open space, they have to crawl on something, and this is really the key aspect to having a scaffold is it allows those cells to have a highway to move on to refill that wound, regenerate that native tissue, Dr. Johnson said.

A Rational Conversation: 2014 Through The Eyes Of A Choreographer

Ryan Heffington.

"A Rational Conversation" is a column by writer Eric Ducker in which he gets on instant messenger or the phone with a special guest to examine a music-related subject that's entered the pop culture consciousness.

To help him wrap his head around music in 2014, Ducker chatted with Ryan Heffington. The Los Angeles-based choreographer and dancer was involved with two videos this year that turned out to be mega high profile phenomenons. He choreographed the video for Sia's "Chandelier," featuring an astounding performance by the then 11-year-old Maddie Ziegler, one of the stars of Lifetime's Dance Moms TV show, as well as the much debated video for Arcade's Fire "We Exist," featuring Andrew Garfield portraying a transgender woman. Other pieces that shouldn't be overlooked include the exquisite roller-skating work Heffington put together for "Gold" by Chet Faker and the showy interludes in Chromeo's "Old 45's." Heffington's work is often notable for the expressive performances that incorporate abstract modern dance movements into more mainstream forms. Here he and Ducker discuss what this year brought us and the types of performances they responded to.

What was your favorite music-related memory or experience of 2014?

There have been so many! One of them for sure was sitting at the Brite Spot after the MTV VMAs and getting a text from Sia telling me congrats. They announced Best Choreography via Twitter (glamorous) and she's how I found out.

What were some of the favorite shows or performances you went to?

Seeing FKA twigs at the Regent recently solidified my appreciation for her. Blood Orange at Coachella was incredible, and performing there [during the first week] with Arcade Fire was epic.

You were on stage with them?

We performed on this 10x10 raised platform in the middle of the audience in daisy dukes, flannels and heels for "We Exist." You can see it on the back screen in the video.

'Wealth care' or next big thing in medicine?

Dr. Alan Sheff, who charges patients an additional $1,800 a year, is able to spend more time with his patients.

NEW YORK (CNNMoney)

Patients can receive this type of comprehensive service from a growing number of primary care doctors who've switched to concierge medicine. But it comes at a price, often hundreds or thousands of dollars a year, and at a time when many Americans are already struggling to afford their insurance and medical care.

Concierge doctors generally charge patients a membership fee -- typically $1,800 a year -- outside of the traditional insurance system. They often have fewer patients -- usually no more than 600, compared to 2,500-plus for a typical physician -- so they can spend more time with each one.

Beyond those common traits, there are many models of concierge medicine, which is also called private physician or direct pay practices. Some doctors target the wealthy, charging five-figures to handle all aspects of their health care, from negotiating bills with hospitals to being in the operating room. Others charge a flat rate of $50 a month for appointments.

For some physicians, the annual fee covers all office visits. At other practices, it only buys patients a comprehensive yearly exam, as well as same-day appointments and after-hours access.

Whatever the model, patients still need traditional insurance to cover specialists' visits, hospitalizations and other diagnostic testing, such as MRIs.

Related: Paying thousands before health insurance even kicks in

Many doctors shy away from the term "concierge" because it connotes that it's for an exclusive club. They are not practicing "wealth care," as a few of those interviewed termed it.

Instead, these doctors are increasingly positioning themselves as health care providers for middle class Americans who value wellness.

Suzanne Crouch Downplaying IU Medical School Concerns

A state leader downplaying the IU Medical School being left off the Indiana Commission for Higher Education's list of recommended projects.

As we've reported, Indiana University ranked the Evansville medical school project as sixth out of six items.

However, State Auditor Suzanne Crouch says it shouldn't be too worrisome. That's because two years ago, Crouch says lawmakers set aside $2 million to get the project going.

"The fact that this was not in the recommendations does not really mean a thing," said Crouch, "because it's the Indiana General Assembly that makes the funding choices. In fact two years ago, when we put together the budget, that $2 million that started the IU School of Medicine was not on the Commission on Higher Education's recommendations."

Crouch says in her conversations with Governor Mike Pence and his budget agency, there is tremendous support for the project. The general assembly reconvenes early next month.
