NASA GODDARD SPACE FLIGHT CENTER, MD – Why is NASA’s Commercial Crew Program to develop private human transport ships to low Earth orbit important?

That’s the question I posed to NASA Administrator Charles Bolden when we met for an exclusive interview at NASA Goddard.

The Commercial Crew Program (CCP) is the critical enabler “for establishing a viable orbital infrastructure” in the 2020s, NASA Administrator Charles Bolden told Universe Today in an exclusive one-on-one interview at NASA’s Goddard Space Flight Center in Greenbelt, Md.

Bolden, a Space Shuttle commander who flew four time to space, says NASA wants one of the new American-made private crewed spaceships under development by SpaceX, Boeing and Sierra Nevada – with NASA funding – to be ready to ferry US astronauts to the International Space Station (ISS) and back to Earth by late 2017. Flights for other commercial orbital space ventures would follow later and into the next decade.

Since the shutdown of NASA’s space shuttle program following the final flight by STS-135 in 2011 (commanded by Chris Ferguson), America has been 100% dependent on the Russians to fly our astronauts to the space station and back.

“Commercial crew is critical. We need to have our own capability to get our crews to space,” Bolden told me, during a visit to the NASA Goddard cleanroom with the agency’s groundbreaking Magnetospheric Multiscale (MMS) science probes.

Administrator Bolden foresees a huge shift in how the US will conduct space operations in low earth orbit (LEO) just a decade from now. The future LEO architecture will be dominated not by NASA and the ISS but rather by commercial entrepreneurs and endeavors in the 2020s.

“There are going to be other commercial stations or other laboratories,” Bolden excitedly told me.

And the cash strapped Commercial Crew effort to build new astronaut transporters is the absolutely essential enabler to get that exploration task done, he says.

“Commercial Crew is critical to establishing the low Earth orbit infrastructure that is required for exploration.”

“We have got to have a way to get our crews to space.”

“You know people try to separate stuff that NASA does into nice little neat packages. But it’s not that way anymore.”

Bolden and NASA are already looking beyond the ISS in planning how to use the new commercial crew spaceships being developed by SpaceX, Boeing and Sierra Nevada in a public- partnership with NASA’s Commercial Crew Program.

“Everything we do [at NASA] is integrated. We have to have commercial crew [for] a viable low Earth orbit infrastructure – a place where we can do testing – for example with what’s going on at the ISS today.”

“And in the out years you are going to be doing the same type of work.”

“But it’s not going to be on the ISS.”

“After 2024 or maybe 2028, if we extend it again, you are going to see the people on commercial vehicles. There are going to be other stations or other laboratories.”

“But there won’t be NASA operated laboratories. They will be commercially viable and operating laboratories.”

Private NewSpace ventures represent a revolutionary departure from current space exploration thinking. But none of these revolutionary commercial operations will happen if we don’t have reliable and cost effective human access to orbit from American soil with American rockets on American spaceships.

“We need to have our own capability to get our crews to space – first of all. That’s why commercial crew is really, really, really important,” Bolden emphasized.

The ongoing crises in Ukraine makes development of a new US crew transporter to end our total reliance on Russian spaceships even more urgent.

“Right now we use the Russian Soyuz. It is a very reliable way to get our crews to space. Our partnership with Roscosmos is as strong as it’s ever been.”

“So we just keep watching what’s going on in other places in the world, but we continue to work with Roscosmos the way we always have,” Bolden stated.

The latest example is this week’s successful launch of the new three man Russian-US- German Expedition 40 crew to the ISS on a Soyuz.

Of course, the speed at which the US develops the private human spaceships is totally dependent on the funding level for the Commercial Crew program.

Unfortunately, progress in getting the space taxis actually built and flying has been significantly slowed because the Obama Administration CCP funding requests for the past few years of roughly about $800 million have been cut in half by a reluctant US Congress. Thus forcing NASA to delay the first manned orbital test flights by at least 18 months from 2015 to 2017.

And every forced postponement to CCP costs US taxpayers another $70 million payment per crew seat to the Russians. As a result of the congressional CCP cuts more than 1 Billion US Dollars have been shipped to Russia instead of on building our own US crew transports – leaving American aerospace workers unemployed and American manufacturing facilities shuttered.

I asked Bolden to assess NASA’s new funding request for the coming fiscal year 2015 currently working its way through Congress.

“It’s looking better. It’s never good. But now it’s looking much better,” Bolden replied.

“If you look at the House markup that’s a very positive indication that the budget for commercial crew is going to be pretty good.”

The pace of progress in getting our crews back to orbit basically can be summed up in a nutshell.

“No Bucks, No Buck Rogers,” Chris Ferguson, who now leads Boeing’s crew effort, told me in a separate exclusive interview for Universe Today.

The Boeing CST-100, Sierra Nevada Dream Chaser and SpaceX Dragon ‘space taxis’ are all vying for funding in the next round of contracts to be awarded by NASA around late summer 2014 known as Commercial Crew Transportation Capability (CCtCap).

All three company’s have been making excellent progress in meeting their NASA mandated milestones in the current contract period known as Commercial Crew Integrated Capability initiative (CCiCAP) under the auspices of NASA’s Commercial Crew Program.

Altogether they have received more than $1 Billion in NASA funding under the current CCiCAP initiative. Boeing and SpaceX were awarded contracts worth $460 million and $440 million, respectively. Sierra Nevada was given what amounts to half an award worth $212.5 million.

SpaceX CEO Elon Musk just publicly unveiled his manned Dragon V2 spaceship on May 29.

Boeing’s Chris Ferguson told me that assembly of the CST-100 test article starts soon at the Kennedy Space Center.

NASA officials have told me that one or more of the three competitors will be chosen later this year in the next phase under CCtCAP to build the next generation spaceship to ferry astronauts to and from the ISS by 2017.

In order to certify the fitness and safety of the new crew transporters, the CCtCAP contracts will specify that “each awardee conduct at least one crewed flight test to verify their spacecraft can dock to the space station and all its systems perform as expected.”

Concurrently, NASA is developing the manned Orion crew vehicle for deep space exploration. The state-of-the-art capsule will carry astronauts back to the Moon and beyond on journeys to Asteroids and one day to Mars.

“We need to have our own capability to get our crews to space. Commercial Crew is critical to establishing the low Earth orbit infrastructure that is required for exploration,” that’s the bottom line message from my interview with NASA Administrator Bolden.

Stay tuned here for Ken’s continuing SpaceX, Boeing, Sierra Nevada, Orbital Sciences, commercial space, Orion, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Watch All The Apollo Saturn V Rockets Blast Off At The Same Time

Screenshot of a video showing all the Saturn V launches happening at the same time. Credit: SpaceOperaFR/YouTube (screenshot)

Editor’s note: We posted this yesterday only to find that the original video we used had been pulled. Now, we’ve reposted the article with a new and improved version of the video, thanks to Spacecraft Films.

To the moon! The goal people most remember from the Apollo program was setting foot on the surface of our closest neighbor. To get there required a heck of a lot of firepower, bundled in the Saturn V rocket. The video above gives you the unique treat of watching each rocket launch at the same time.

Some notes on the rockets you see:

  • Apollos 4 and 6 were uncrewed test flights.
  • Apollo 9 was an Earth-orbit flight to (principally) test the lunar module.
  • Apollo 8 and 10 were both flights around the moon (with no lunar landing).
  • Apollo 13 was originally scheduled to land on the moon but famously experienced a dangerous explosion that forced the astronauts to come back to Earth early — but safely.
  • Apollos 11, 12, 14, 15, 16 and 17 safely made it to the moon’s surface and back.
  • Skylab’s launch was also uncrewed; the Saturn V was used in this case to send a space station into Earth’s orbit that was used by three crews in the 1970s.
  • You don’t see Apollo 7 pictured here because it did not use the Saturn V rocket; it instead used the Saturn IB. It was an Earth-orbiting flight and the first successful manned one of the Apollo program. (Apollo 1 was the first scheduled crew, but the three men died in a launch pad fire.)

And if this isn’t enough firepower for you, how about all 135 space shuttle launches at the same time?

New Arecibo Radar Images Show Comet Responsible for Camelopardalids is an Icy, Cratered Mini World

Radar images of Comet 209P/LINEAR taken from May 23 through May 27, 2014. The Earth is at the bottom of these images: the “side view” is a result of the radar imaging method. Several features are visible on the comet, perhaps ridges or cliffs. This is only the fifth comet nucleus imaged by Arecibo in the last 16 years, and the most detailed. Resolution in the vertical direction is 7.5 meters (25 feet) per pixel. Image credit: Arecibo Observatory/NASA/Ellen Howell.

When Comet 209P/LINEAR — the comet that brought us the Camelopardalids meteor shower last weekend – was first discovered in February of 2004, astronomers initially thought it was an asteroid. However, subsequent images of the objects showed it had a tail, and so it was reclassified as a comet. Now, new images taken by the Arecibo Observatory planetary radar system reveal Comet 209P/LINEAR has complex surface features that will require more analysis to fully interpret. This mini world seems to be filled with ridges and cliffs along with its icy surface.

“This is the highest resolution radar image we have obtained of a comet nucleus,” said Dr. Ellen Howell from the Universities Space Research Association, who led the observations of the comet at Arecibo, located in Puerto Rico.

The Arecibo Observatory is taking advantage of the approaching close pass of Earth by Comet 209P/LINEAR, taking these new radar images which confirm this comet to be about 2.4 by 3 km kilometers (1.5 x 1.8 miles) in size and elongated in shape. Earlier optical observations suggested this size range, but now these radar observations are the first direct measurement of the nucleus dimensions.

Comets very rarely come this close to Earth, but don’t worry: Comet 209P/LINEAR is not coming close enough to cause any problems or concerns.

“Comet 209P/LINEAR has no chance of hitting Earth,” said data analyst Alessondra Springmann from Arecibo. “It comes no closer than 8.3 million kilometers (5.2 million miles) to Earth, safely passing our planet.”

But this relatively close pass makes this an extraordinary opportunity to get images of the surface. As Dr. Howell noted, these observations of are some of the most detailed. Just six comet nuclei have been imaged by spacecraft, and a wide variety of surface features and structures have been observed on these icy objects.

“We are being cautious,” Howell told Universe Today. “Radar images are not regular “spatial” images, and one can easily be misled by treating them as a regular picture. But proper analysis will take weeks or months, not minutes. What these radar images show is certainly not ordinary, but we don’t really have anything to compare to. The image looks different than asteroids we have imaged, but I don’t know what is due to surface feature differences and what might be scattering differences by the surface material.”

Comets have a central nucleus made of ice, dust, and rocks, and a coma of dust and gas. Two tails, one made of ions and one of dust, form in the direction pointing away from the sun.

Other comets seen by Arecibo radar include 103P/Hartley 2 and 8P/Tuttle, and 73P/Schwassmann-Wachmann 3.

Unlike long period comets Hale-Bopp and the late Comet ISON that swing around the Sun once every few thousand years or few million years, Comet 209P/LINEAR visits our neighborhood frequently, coming ‘round every 5.09 years. However, it will not be close enough to Earth again for radar imaging any time in the next 100 years.

With a rotation period of approximately 11 hours as determined by Carl Hergenrother at the University of Arizona using the 1.8 meter VATT telescope, this comet is one of the many Jupiter family comets, which orbit the Sun twice for every time Jupiter orbits once.

It was discovered by the Lincoln Laboratory Near-Earth Asteroid Research (LINEAR) automated sky survey.

The Arecibo Observatory, located in Puerto Rico, is home to the world’s largest and most sensitive single-dish radio telescope at 305 meters (1000feet) across. This facility dedicates hundreds of hours a year of its telescope time to improving our knowledge of near-Earth asteroids and comets.

Dr. Howell specializes in studying comets and asteroids using radar, as well as passive radio and infrared spectroscopy techniques to determine the surface and coma properties of small solar system bodies. She was assisted in these observations of Comet 209P/LINEAR by Michael Nolan, Patrick Taylor, Alessondra Springmann, Linda Ford, and Luisa Zambrano.

Arecibo Observatory, and the complementary Goldstone Solar System Radar in California run by NASA’s Jet Propulsion Laboratory, are both observing comet 209P/LINEAR during its pass by Earth in May. These radar facilities are unique among telescopes on Earth for their ability to resolve features on comets and asteroids, while most optical telescopes on the ground would see these cosmic neighbors simply as unresolved points of light.

For more images and information on Comet 209P/LINEAR, see the Arecibo Observatory’s planetary radar page.

The Arecibo Observatory is operated by SRI International under a cooperative agreement with the National Science Foundation, and in alliance with the Sistema Universitario Ana G. Méndez-Universidad Metropolitana and the Universities Space Research Association. The Arecibo Planetary Radar program is supported by NASA’s Near Earth Object Observation program.

There Might Be 100 Million Planets In The Galaxy With Complex Life

What a multitude of worlds! A new study suggests that the Milky Way could host 100 million planets with complex life, leaving no lack of choice for astronomers to look for organisms beyond Earth. The challenge is, however, that these worlds might be too far away from us to do much yet.

“On the one hand, it seems highly unlikely that we are alone,” stated Louis Irwin, lead author of the study and professor emeritus at the University of Texas at El Paso. “On the other hand, we are likely so far away from life at our level of complexity, that a meeting with such alien forms is extremely improbable for the foreseeable future.”

The figure came from studying a list of more than 1,000 exoplanets for metrics such as their density, temperature, chemistry, age and distance from the parent star. From this, Irwin’s team formulated a “biological complexity index” that ranges between 0 and 1.0. The index is rated on “the number and degree of characteristics assumed to be important for supporting multiple forms of multicellular life,” the research team stated.

Assuming that Europa (a moon of Jupiter believed to have an ocean below its ice) is a good candiate for life, the team estimated that 1% to 2% of exoplanets would have a BCI that is even higher than that. So to translate that into some estimates: 10 billion stars in the Milky Way, averaging one planet a star, which brings us to 100 million planets minimum.

So what does this metric mean? There’s of course no guarantee that complex life exists in any of these places — just that the conditions could be conducive to life. Also, the researchers added, don’t assume that any life in this category would be intelligent life, but more life that is more complex than a microbe. And the known planets with higher BCIs tend to be pretty far away from us. (One of the closest is the Gliese 581 system, which is 20 light-years away.)

Read more about the research in the journal Challenges. Recall that a few years ago, this group also wrote about an “Earth Similarity Index” rating exoplanets on how close they are to our own.

“Planets with the highest BCI values tend to be larger, warmer, and older than Earth,” added Irwin, “so any search for complex or intelligent life that is restricted just to Earth-like planets, or to life as we know it on Earth, will probably be too restrictive.”

Video: Beyond Neptune, It Sure Is Crowded With Icy Objects

Faster than you can say “trans-Neptunian object” three times, the reaches beyond Neptune’s orbit start to fill out in this animation. And it’s astounding. Dots representing icy bodies large and small fill the area.

What’s more sobering is realizing how little we knew about this region 20 years ago. Pluto was the first object in that region discovered in 1930, and it wasn’t until 1992 QB1 was discovered that our understanding of this neighborhood increased, wrote creator Alex Parker, a planetary astronomer at the University of California, Berkeley.

“Made this for a talk I gave today. I think it came out pretty nice,” Parker wrote yesterday (May 29) on Twitter.

Parker added on the video page: “This animation illustrates the approximate relative sizes and the true orbital motion of all known trans-Neptunian objects with average orbital distances (semi-major axes) greater than Neptune’s. The objects are revealed on the date of their discovery. Data extracted from the Minor Planet Center database.”

On Twitter, he also provided a link to another visualization of asteroid discoveries between 1980 and 2011 by Scott Manley:

What a gorgeous deep sky astrophoto! M20, also known as the Trifid Nebula is located in Sagittarius, and its name means ‘divided into three lobes.’ The ‘lobes’ are clearly visible in this very pretty palette of colors by astrophotographer Ian Sharp.

“I’ve been agonising about this one because it was a real struggle to find a palette that worked because the Hα data was so strong,” Ian told Universe Today via email. He said the regular Hubble palette caused a very green result, so instead he used this mix of channels:

R: (Hα x 0.50) + (SII x 0.50)
G: (OIII x 0.85) + (Hα x 0.15)
B: OIII

This was taken remotely from Siding Spring Observatory in Australia over the past few weeks, with 38 hours of exposure.

Hα: 27 x 1800s
OIII: 28 x 1800s
SII: 21 x 1800s

Here’s the link to the photo on Ian’s website.

SpaceX CEO and billionaire founder Elon Musk gushed with excitement as he counted down the seconds and literally pulled the curtain away to unveil his company’s new manned Dragon V2 astronaut transporter for all the world to see during a live streaming webcast shortly after 10 p.m. EST (7 p.m. PST, 0200 GMT) this evening, Thursday, May 29, from SpaceX HQ.

The first photos from the event are collected herein. And I’ll be adding more and updating this story as they flow in.

Musk’s Dragon V2 unveiling was brimming with excitement like a blockbuster Hollywood Science Fiction movie premiere – with lights, cameras and action.

But this was the real deal and hopefully gets America moving again back to thrilling, real space adventures in orbit and beyond – reaching for the stars.

“The Dragon V2 is a 21st century spacecraft,” Musk announced to a wildly cheering crowd. “As it should be.”

“We wanted to take a big step in spacecraft technology. It is a big leap forward in technology and takes things to the next level.”

“An important characteristic of that is its ability to land anywhere on land, propulsively. It can land anywhere on Earth with the accuracy of a helicopter.”

“I think that’s what a spaceship should be able to do.”

“It will be capable of carrying seven astronauts. And it will be fully reusable.”

But Musk and SpaceX are not alone in striving to get Americans back to space.

Two other US aerospace firms – Boeing and Sierra Nevada – are competing with SpaceX to build the next generation spaceship to ferry astronauts to and from the ISS by 2017 using seed money from NASA’s Commercial Crew Program in a public/private partnership.

Altogether they have received more than $1 Billion in NASA funding.

The Boeing CST-100 and Sierra Nevada Dream Chaser ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

The ‘Dragon V2’ is an upgraded, man-rated version of the unmanned Dragon cargo spaceship that just completed its third operational resupply mission to the ISS with a successful splashdown in the Pacific Ocean on May 18.

Stay tuned here for Ken’s continuing SpaceX, Boeing, Sierra Nevada, Orbital Sciences, commercial space, Orion, Mars rover, MAVEN, MOM and more planetary and human spaceflight news.

Read my “Dragon V2” or “Dragon Version 2” preview story – here.

Musk’s (and NASA’s) goal is to restore America’s capability to launch US astronauts to low Earth orbit and the International Space Station (ISS) by 2017 and to put an end total US dependency on Russia’s Soyuz for astronaut rides to orbit and back.

“SpaceX’s new Dragon V2 spacecraft is a next generation spacecraft designed to carry astronauts into space,” says SpaceX.

“Cover drops on May 29. Actual flight design hardware of crew Dragon, not a mockup,” Musk tweeted recently to build anticipation.

Dragon is among a trio of US private sector manned spaceships being developed with seed money from NASA’s Commercial Crew Program in a public/private partnership to develop a next-generation crew transportation vehicle to ferry astronauts to and from the ISS by 2017 – a capability totally lost following the space shuttle’s forced retirement in 2011.

The Boeing CST-100 and Sierra Nevada Dream Chaser ‘space taxis’ are also vying for funding in the next round of contracts to be awarded by NASA around late summer 2014.

The gumdrop-shaped ‘Dragon V2’ is an upgraded, man rated version of the unmanned Dragon spaceship that will carry a mix of cargo and up to a seven crewmembers to the International Space Station (ISS).

The cargo Dragon just successfully completed its third operational resupply mission to the ISS with a successful splashdown in the Pacific Ocean on May 18.

The Battle Against What Spaceflight Does To Your Health

Why do some astronauts come back from the International Space Station needing glasses? Eye problems are one of the largest problems that have cropped up in the last three to four years of space station science, affecting 20% of astronauts. And the astronaut office is taking this problem very seriously, pointed out Scott Smith, who leads the Nutritional Biochemistry Lab at the Johnson Space Center.

It’s one example of how extended stays in flight can alter your health. Despite NASA’s best efforts, bones and muscles weaken and months of rehabilitation are needed after astronauts spend a half-year on the space station. But in recent years, there have been strides in understanding what microgravity does to the human body — and how to fix it.

Take the vision problem, for example. Doctors believed that increased fluid shift in the head increases pressure on the optic nerve, a spot in the back of the eye that affects vision. There are a few things that could affect that:

  • Exercise. Astronauts are told to allot 2.5 hours for exercise on the International Space Station daily, which translates to about 1.5 hours of activity after setup and transitions are accounted for. Weight lifting compresses muscles and could force more blood into their heads. NASA installed an advanced Resistive Exercise Device on the space station that is more powerful than its predecessor, but perhaps this is also causing the vision problem, Smith said. “It’s ironic that the exercise device we’re excited about for working the muscles and bone, may hurt eyes.”
  • CO2 levels. This gas (which naturally occurs when humans exhale) is “relatively high” on the space station because it takes more power and more supplies to keep the atmosphere cleaner, Smith said. “Increased carbon dioxide exposure will increase blood flow to your head,” he said. If this is found to be the cause, he added, NASA is prepared to make changes to reduce CO2 levels on station.
  • Folate (Vitamin B) problems. Out of the reams of blood and urine data collected since before NASA started looking at this problem, they had been looking at a biochemical (nutrient) pathway in the body that moves carbon units from one compound to another. This is important for synthesizing DNA and making amino acids, and involves several vitamins and nutrients. After scientists started noticing changes in folate (a form of Vitamin B), they probed further and found an interesting thing regarding homocysteine, a type of amino acid at the heart of this one carbon pathway. It turns out those astronauts with vision issues after flight had higher (but not abnormal) levels of homocysteine in their blood before flight, as published here.

“It’s speculating, but we think that genetic differences in this pathway may somehow alter your response to things that affect blood flow into the head,” Smith said.

After finding these essentially “circumstantial” evidence of a genetic predisposition to vision issues, they proposed an experiment to look at genes associated with one carbon metabolism. “To give you an idea of the importance of this problem, we went to every crew member that’s flown to space station, or will fly to space station.  We asked if they would give us a blood sample and look at their genes for one carbon meytabolism,” he said. “We approached 72 astronauts to do that, and 70 of them gave us blood, which is unheard of.”

While NASA tries to nail down what is going on with astronaut vision, the agency has made substantial progress in preserving bone density during flights — for the first time in 50 years of spaceflight, Smith added.

We mentioned the advanced Resistive Exercise Device, an orbital weight-lifting device which was installed and first used during Expedition 18 in 2008 and has been in use on the space station ever since. It’s a large improvement over the previous interim Resistive Exercise Device (iRED), which didn’t provide enough resistance, allowing some astronauts to “max out” on the device and could not further increase weightlifting loads after some weeks or months of use.

“We flew the iRED on station and the bone loss on station looked just like it did on Mir, that is, with no resistive exercise device available,” Smith said. But that changed drastically with ARED, which has twice as much loading capability. Crews ate better, maintained body weight and had better levels of Vitamin D compared to those that went before. Most strikingly, they maintained their bone density at preflight levels, as this paper shows.

While we think of bone as being cement-like and unchanging (at least until you break one!), it’s actually an organ that is always breaking down and reforming. When the breakdown accelerates, such as when you are not putting weight on it in orbit, you lose bone density and are at higher risk for fractures.

Why is unknown, except to say that the bone seems to rely on some sort of “signalling” that indicates loads or weights are being put on it. Conversely, if you are to put more weight on your bones — maybe carrying a backpack with weights on it — your skeleton would gradually get bigger to accommodate the extra weight.

While it’s exciting that the ARED is maintaining bone density, the question is whether the body can sustain two processes happening at a faster rate than before flight: the breakdown and buildup of bone. More study will be needed, Smith said, to pinpoint whether this affects the strength of the bone, which is ultimately more important than just mineral density. Nutrition and exercise may also be optimized, to further allow for better bone preservation.

That’s one of the things scientists are excited to study with the upcoming one-year mission to the International Space Station, when Scott Kelly (NASA) and Mikhail Kornienko (Roscosmos) will be one of a small number of people to do one consecutive calendar year in space. The bone “remodelling” doesn’t level off after six months, but perhaps it will closer to a year.

Smith pointed out the quality of health data has also improved since the long-duration Mir missions of the early to mid 1990s. Specific markers of bone breakdown and formation were just being discovered and implemented during that time, whereas today they’re commonly used in medicine. Between that, and the fact that NASA’s Mir data are from shorter-duration missions, Smith said he’s really looking forward to seeing what the year in space will tell scientists.
