KENNEDY SPACE CENTER, FL – Boeing expects to begin “assembly operations of our commercial CST-100 manned capsule soon at the Kennedy Space Center,” Chris Ferguson, commander of NASA’s final shuttle flight and now director of Boeing’s Crew and Mission Operations told Universe Today in an exclusive one-on-one interview about Boeing’s space efforts. In part 1, Ferguson described the maiden orbital test flights to the ISS set for 2017 – here.

In part 2, we focus our discussion on Boeings’ strategy for building and launching the CST-100 ‘space taxi’ as a truly commercial space endeavor.

To begin I asked; Where will Boeing build the CST-100?

“The CST-100 will be manufactured at the Kennedy Space Center (KSC) in Florida inside a former shuttle hanger known as Orbiter Processing Facility 3, or OPF-3, which is now [transformed into] a Boeing processing facility,” Ferguson told me. “Over 300 people will be employed.”

During the shuttle era, all three of NASA’s Orbiter Processing Facilities (OPFs) were a constant beehive of activity for thousands of shuttle workers busily refurbishing the majestic orbiters for their next missions to space. But following Ferguson’s final flight on the STS-135 mission to the ISS in 2011, NASA sought new uses for the now dormant facilities.

So Boeing signed a lease for OPF-3 with Space Florida, a state agency that spent some $20 million modernizing the approximately 64,000 square foot hanger for manufacturing by ripping out all the no longer needed shuttle era scaffolding, hardware and equipment previously used to process the orbiters between orbital missions.

Boeing takes over the OPF-3 lease in late June 2014 following an official handover ceremony from Space Florida. Assembly begins soon thereafter.

When will CST-100 spacecraft manufacturing begin?

“The pieces are coming one by one from all over the country,” Ferguson explained. “Parts from our vendors are already starting to show up for our test article.

“Assembly of the test article in Florida starts soon.”

The CST-100 is being designed at Boeing’s Houston Product Support Center in Texas.

It is a reusable capsule comprised of a crew and service module that can carry a mix of cargo and up to seven crew members to the International Space Station (ISS) and must meet stringent safety and reliability standards.

How will the pressure vessel be manufactured? Will it involve friction stir welding as is the case for NASA’s Orion deep space manned capsule?

“There are no welds,” he informed.

“The pressure vessel is coming from Spincraft, an aerospace manufacturing company in Massachusetts.”

Spincraft has extensive space vehicle experience building tanks and assorted critical components for the shuttle and other rockets.

“The capsule is produced by Spincraft using a weld-free process. It’s made as a single piece by a proprietary spun form process and machined out from a big piece of metal.”

The capsule measures approximately 4.56 meters (175 inches) in diameter.

“The service module will be fabricated in Florida.”

The combined crew and service modules are about 5.03 meters (16.5 feet) in length.

“In two years in 2016, our CST-100 will look like the Orion EFT-1 capsule does now at KSC, nearly complete [and ready for the maiden test flight]. Orion is really coming along,” Ferguson beamed while contemplating a bright future for US manned spaceflight.

He is saddened that it’s been over 1000 days since his crew’s landing inside shuttle Atlantis in July 2011.

With Boeing’s long history in aircraft and aerospace manufacturing, the CST-100 is being designed and built as a truly commercial endeavor.

Therefore the spacecraft team is able to reach across Boeing’s different divisions and diverse engineering spectrum and draw on a vast wealth of in-house expertise, potentially giving them a leg up on commercial crew competitors like SpaceX and Sierra Nevada Corp.

Nevertheless, designing and building a completely new manned spaceship is a daunting task for anyone. And no country or company has done it in decades.

How hard has this effort been to create the CST-100? – And do it with very slim funding from NASA and Boeing.

“Well any preconceived notion I had on building a human rated spacecraft has been completely erased. This is really hard work to build a human rated spacecraft!” Ferguson emphasized.

“And the budget is very small – without a lucrative government contract as used in the past to build these kind of spacecraft.”

“Our budget now is an order of magnitude less than to build the shuttle – which was about $35 to $42 Billion in 2011 dollars. The budget is a lot less now.”

Read more about the travails of NASA’s commercial crew funding situation in Part 1.

The team size now is just a fraction of what it was for past US crewed spaceships.

“So to support this we have a pretty small team.”

“The CST-100 team of a couple hundred folks works very hard!”

“For comparison, the space shuttle had 30,000 people working on it at the peak. By early 2011 there were 11,000. We flew on STS-135 with only 4,000 people in July 2011.”

Boeing’s design philosophy is straightforward; “It’s a simple ride up to and back from space,” Ferguson emphasized to me.

Next we turned to the venerable Atlas V rocket that will launch Boeing’s proposed space taxi. But before it can launch people it must first be human rated, certified as safe and outfitted with an Emergency Detection System (EDS) to save astronauts lives in a split second in case of a sudden and catastrophic in-flight anomaly.

United Launch Alliance (ULA) builds the two stage Atlas V and is responsible for human rating the vehicle which has a virtually unblemished launch record of boosting a wide array of advanced US military satellites and NASA’s precious one-of-a-kind robotic science explorers like Curiosity, JUNO, MAVEN and MMS on far flung interplanetary voyages of discovery.

What modifications are required to man rate the Atlas V to launch humans on Boeing’s CST-100?

“We will launch on an Atlas V that’s being retrofitted to meet NASA’s NPR human rating standards for redundancy and the required levels of fault tolerance,” Ferguson explained.

“So the rocket will have all the safety NASA wants when it flies humans.”

“Now with the CST-100 you can do all that in a smaller package [compared to shuttle].”

“The Atlas V will also be modified by ULA to include an Emergency Detection System (EDS). It’s a system not unlike what Apollo and Gemini had, which was much more rudimentary but quite evolved for its day.”

“Their EDS would monitor critical parameters like pitch, roll, yaw rates, critical engine parameters. It measures the time to criticality. You know the time to criticality for certain failures is so short that they didn’t think humans could react to it in time. So it was essentially automated.”

“So if it [EDS] sensed large pitch or yaw excursions, it would self jettison. And the escape system would kick in automatically.”

The Atlas V is already highly reliable. The EDS is one of the few systems that had to be added for human flights?

“Yes.”

“We also wanted a better abort system performance to go with the two engine Centaur upper stage we elected to use instead of the single engine Centaur.”

The purpose is to shut down the Centaur engine firing [in an emergency].”

“The two engine Centaur has flown many times. But it has never flown on an Atlas V. So there is a little bit of recertification and qualification to be done by ULA to go along with that also.”

Does that require a lot of work?

“ULA doesn’t seem to think the work to be done is all that significant. There is some work to be done.”

So it’s not a showstopper. Can ULA meet your 2017 launch schedule?

“Yes.”

“Before an engine fails it vibrates. So when you talk about automated ‘Red Lines’ you have to be careful that first you “Do No Harm” – and not make the situation even worse.”

“So we’ll see how ULA does building this,” Ferguson stated.

The future of the CST-100 project hinges on whether NASA awards Boeing a contract to continue development and assembly work in the next round of funding (dubbed CCtCAP) from the agency’s Commercial Crew Program (CCP). The CCP seed money fosters development of a safe, reliable and new US commercial human spaceship to low Earth orbit as a public/private partnership.

NASA’s announcement of the CCP contract winners is expected around late summer 2014.

Based on my discussions with NASA officials, it seems likely that the agency could select at least two winners to move on – to spur competition and thereby innovation – from among the trio of American aerospace firms competing.

Besides Boeing’s CST-100, the SpaceX Dragon and Sierra Nevada Dream Chaser vehicles are also in the running for the contract to restore America’s capability to fly humans to Earth orbit and the International Space Station (ISS) by 2017.

In Part 3 we’ll discuss with Chris Ferguson the requirements for how many and who will fly aboard the CST-100 and much more. Be sure to read Part 1 here.

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

Spitzer Mission Extension Not Approved In NASA Senior Review; Officials Say Budget Rewrite Possible

“Constrained budget conditions” have prompted NASA to not approve a funding extension for the 11-year-old Spitzer Space Telescope after fiscal 2015, but Spitzer officials emphasized that doesn’t necessarily mean the mission is terminated.

“To be clear: Spitzer has not been canceled. Funding not yet identified, but NASA has asked us for a revised budget,” the Spitzer Twitter account wrote to several individuals after news broke that the telescope was not approved in agency’s Senior Review, a process to see how well ongoing missions are performing to expectations.

What this means is that the telescope is expected to go with the “baseline” plan to finish operations after the end of fiscal 2014 and terminate the mission by the end of fiscal 2015, a process that was already outlined in the NASA budget request for 2015. But there’s a chance, officials said, that this would not happen.

“The Spitzer project is invited to respond with a request for a budget augmentation to conduct continued operations with reduced operations costs,” read the NASA response to the 2014 senior review.

This “will be considered during the FY 2016 budget formulation process,” NASA added. “If the administration proposes additional funding for Spitzer in the FY16 Budget, the project will be able to seamlessly continue operations in FY15, while awaiting final appropriations from the Congress for FY16.”

The mission was being reviewed in association with several other astrophysics missions, such as the Kepler space telescope — an exoplanet-hunting probe that was sidelined by a mechanical issue, but was approved in the same review for a new mission.

Spitzer drew concern in the senior review for its “significant current cost”, which is reportedly the most expensive among the missions being considered this time around. The cost also concerned the reviewers because Spitzer’s “observational capabilities are significantly reduced” since the telescope ran out of coolant in 2009.

That said, the so-called “warm” Spitzer mission — which allows it to view different parts of the infrared despite operating at a higher temperature — did impress reviewers with its ability to measure light, especially since it has been able to conduct wide-field surveys that “will not be approached” until the James Webb Space Telescope goes to orbit in 2018.

“The cost is particularly difficult in the context of an observatory with greatly reduced capabilities with respect to its prime mission,” the review read. “The mission also did not present substantial plans to reduce operations costs with such reduced capabilities. Given the budget climate, the SRP cannot recommend funding of Spitzer at the levels requested.”

While criticizing the cost, the senior review also noted Spitzer has been doing a lot of “unexpected science” such as looking at the atmosphere of exoplanets and brown dwarfs, and identifying the galaxies that are speeding away from Earth the fastest (also known as “high-redshift galaxies.”)

According to the Jet Propulsion Laboratory, these are some of Spitzer’s other notable finds:

– Seeing light from a planet outside of the solar system, which was not in the design plans;

– Surveying stars in formation in clouds that are relatively close to Earth;

– Creating a better map of the Milky Way’s spiral arms.

NASA also regularly does image releases with wavelengths from all three of its “Great Observatories”: Spitzer, the Hubble Space Telescope and the Chandra X-Ray Observatory. Funding extension for both Chandra and Hubble were approved in the review. You can read more about the review at this website.

Kepler Space Telescope Gets A New Exoplanet-Hunting Mission

After several months with their telescope on the sidelines, the Kepler space telescope team has happy news to report: the exoplanet hunter is going to do a new mission that will compensate for the failure that stopped its original work.

Kepler’s exoplanet days were halted last year when the second of its four reaction wheels (pointing devices) failed, which meant the telescope could not gaze at its “field” of stars in the Cygnus constellation for signs of exoplanets transiting their stars.

Results of a NASA Senior Review today, however, showed that the telescope will receive the funding for the K2 mission, which allows for some exoplanet hunting, among other tasks. The telescope will essentially change positions several times a year to do its new mission, which is funded through 2016.

“The approval provides two years of funding for the K2 mission to continue exoplanet discovery, and introduces new scientific observation opportunities to observe notable star clusters, young and old stars, active galaxies and supernovae,” wrote Charlie Sobeck, the mission manager for Kepler, in a mission update today (May 16).

“The team is currently finishing up an end-to-end shakedown of this approach with a full-length campaign (Campaign 0), and is preparing for Campaign 1, the first K2 science observation run, scheduled to begin May 30.”

While Kepler itself was not being used for planet hunting, scientific discoveries continue because the telescope has a legacy of observations stretching between 2009 and 2013. One notable find: 715 exoplanets were announced in one swoop earlier this year using a new technique called “verification by multiplicity”, which is useful in multiple-planet systems.

Kepler also spotted the first known Earth-sized planet in a habitable zone outside of our solar system, which achieves the mission’s stated goal of finding extrasolar Earths.

Russian Proton Rocket Fails After Launch, Destroys Satellite: Reports

Archive picture of a Proton launch. Image credit: ILS

About nine minutes after launching towards space, a Russian Proton rocket reportedly crashed Friday (May 16), destroying an advanced satellite being carried on board. The incident happened about 540 seconds after liftoff, after the events of the video shown above.

Russian news site RT (among others) reported that the rocket and Express-AM4R mainly burned up in the atmosphere, meaning no physical damage would be caused to the ground. But this failure marks the latest of several for the Russian rocket type in recent years.

“The exact cause is hard to establish immediately; we will be studying the telemetry. Preliminary information points to an emergency pressure drop in a steering engine of the third stage of the rocket,” said Oleg Ostapenko, the head of the Russian Federal Space Agency (Roscosmos), in a quote cited in RT.

The third stage is called a Breeze-M and reportedly experienced an emergency engine shutdown after the rocket veered on to a different trajectory than it was supposed to. Proton launches have ceased at the Baikonur Space Center in Kazakhstan pending an investigation.

The satellite was supposed to provide “TV and radio broadcasting, broadband Internet access, multimedia services, telephony, [and] mobile communications,” according to the Russian Satellite Communications Company.

Media reports say there have been six failures of this rocket type in the last three or four years. You can read about some of the past failures on Universe Today here:

Venus Express Prepares to Descend into Hell

Artist's impression of the surface of Venus. Credit: ESA/AOES

Venus is definitely not a friendly planet for humanity. Soviet landers that arrived on the surface a few decades back were crushed pretty quickly. Its surface temperature is more than 842 degrees Fahrenheit (450 degrees Celsius) and the atmosphere is full of noxious gases.

But descending into this pressure-filled cooker is exactly what Venus Express is going to do shortly. The European Space Agency spacecraft will conclude eight years of orbital operations with an attempt to fall into the planet. The maneuvers are complicated, and there’s no guarantee they will go as planned, but ESA plans to make the plunge by the end of this year.

For the better part of a decade, Venus Express has been orbiting the planet every 24 hours, swinging in an elliptical orbit that ranges from 155 miles (250 kilometers ) to 41,010 miles (66,000 kilometers). But now the spacecraft is almost out of fuel, and will now be redirected for “experimental aerobreaking” to slow down through skimming the atmosphere.

The maneuvers will take place between June 18 and July 17, where controllers hope to gain some information about the planet’s magnetic field, solar wind, temperature and pressure.

“The campaign also provides the opportunity to develop and practice the critical operations techniques required for aerobraking, an experience that will be precious for the preparation of future planetary missions that may require it operationally,” stated Paolo Ferri, head of mission operations.

No one is sure if the spacecraft will run out of fuel, or even if it survives, but if it does its orbit could be raised to do a few more scientific observations of the planet before going into the atmosphere forever.

Venus’ Express scientific treasure trove includes measuring hydrogen atom escape in the atmosphere, checking out the planet’s clouds and tracking the slowing rotation of the planet (which is happening for reasons that are not quite clear.) It also discovered an ozone layer on the planet.

Mercury’s Ready For Its Close-Up, Mr. MESSENGER

One of the highest-resolution images of Mercury's surface ever acquired.

Are you ready for a good close look at Mercury? At an incredible 5 meters per pixel, this is one of the highest-resolution images of Mercury’s surface ever captured. It was acquired on March 15 with the MESSENGER spacecraft’s MDIS (Mercury Dual Imaging System) instrument and shows an 8.3-km (5.2-mile) -wide section of Mercury’s north polar region, speckled with small craters and softly rolling hills.

Because MESSENGER was moving so quickly relative to the targeted area it was imaging, a short exposure time was necessary to avoid blurring. As a result the image appears a bit grainy. See the original map projection here.

Wondering what the next-best image was of Mercury? Find out below:

The previous record for most extreme close-up of Mercury was held by this image:

7 meter/pixel targeted observation of Mercury by the MESSENGER spacecraft

It was acquired as a targeted observation by MESSENGER’s Narrow-Angle Camera on April 30, 2012, and has a resolution of 7 meters/pixel. It shows an impact melt-covered area about 11 km (7 miles) across near Gaugin crater.

(Although Mercury’s surface may at first appear strikingly similar to the Moon’s, it’s been known since the Mariner 10 mission that the two worlds are very different at fundamental geologic and compositional levels. Read more on that here.)

Images like these are extremely special; during the first two years of MESSENGER’s mission in orbit around Mercury, over 150,000 images were acquired but only five images had resolutions better than 10 meters per pixel.

Artist's impression of MESSENGER orbiting Mercury — Artist’s impression of MESSENGER orbiting Mercury

On April 20, 2014, MESSENGER completed its 3,000th orbit of Mercury (3,075 to date) and is steadily moving into an even lower-altitude orbit. MESSENGER now comes within less than 200 km (124 miles) of the planet’s surface when it passes over its north pole every eight hours… that’s less than half the altitude of the Space Station!

Orbiting at such a low altitude and so often will allow MESSENGER to examine Mercury’s surface in unprecedented detail. Now that 100% of the planet has been successfully mapped by MESSENGER it can spend its second — and last — extended mission investigating specific scientific targets.

Watch: A Tribute to MESSENGER

“The final year of MESSENGER’s orbital operations will be an entirely new mission,” said Sean Solomon, Principal Investigator for MESSENGER. “With each orbit, our images, our surface compositional measurements, and our observations of the planet’s magnetic and gravity fields will be higher in resolution than ever before. We will be able to characterize Mercury’s near-surface particle environment for the first time. Mercury has stubbornly held on to many of its secrets, but many will at last be revealed.”

Astrophotos: Occultation of Saturn

Observers in Australia and New Zealand had a special treat this week: watching Saturn disappear behind the Moon during an event called an occultation. (You can read all the details of how and why this happens here in our preview article.) Catching an event like this with a camera is tricky… the bright Moon can wash out the comparatively tiny (from our vantage point) planet Saturn. But here, several astrophotographers had success. Above is a nice view from Silveryway on Flickr.

See an animation of the event below from astroblogger Ian Musgrave:

Peter Lake, also from Australia not only took images of the event, but also did a live Hangout on G+.

“Live hangouts and driving a telescope live is a tricky business,” Peter wrote on his website. “I lost focus playing around trying to improve the image due to the thin cloud.” He added that the night sky wasn’t ideal that evening. “The full moon was shining through thin clouds, washing out a bit of the detail.”

Hubble Sees Jupiter’s Red Spot Shrink to Smallest Size Ever

In this comparison image the photo at the top was taken by Hubble's Wide Field Planetary Camera 2 in 1995 and shows the spot at a diameter of just under 21 000km; the second down shows a 2009 WFC3 photo of the spot at a diameter of just under 18 000km; and the lowest shows the newest image from WFC3 taken in 2014 with the spot at its smallest yet, with diameter of just 16 000km. Credit: NASA/ESA

Earlier this year we reported that amateur astronomers had observed and photographed the recent shrinking of Jupiter’s iconic Great Red Spot. Now, astronomers using the Hubble Space Telescope concur:

“Recent Hubble Space Telescope observations confirm that the spot is now just under 10,250 miles (16,500 km) across, the smallest diameter we’ve ever measured,” said Amy Simon of NASA’s Goddard Space Flight Center in Maryland, USA.

Drawing of Jupiter made on Nov. 1, 1880 by French artist and astronomer Etienne Trouvelot showing transiting moon shadows and a much larger Great Red Spot.

Using historic sketches and photos from the late 1800s, astronomers determined the spot’s diameter then at 25,475 miles (41,000 km) across. Even the smallest telescope would have shown it as a huge red hot dog. Amateur observations starting in 2012 revealed a noticeable increase in the spot’s shrinkage rate.

The spot’s “waistline” is getting smaller by just under 620 miles (1,000 km) per year while its north-south extent has changed little. In a word, the spot has downsized and become more circular in shape. Many who’ve attempted to see Jupiter’s signature feature have been frustrated in recent years not only because the spot’s pale color makes it hard to see against adjacent cloud features, but because it’s physically getting smaller.

Jupiter's Great Red Spot or GRS is located in a 'bay' or hollow south of the South Equatorial Belt. It's a swirling storm that rises above the cloud tops of the planet and rotates in a counterclockwise direction with a period of about This photo was taken by Hubble on April 21, 2014. — Jupiter’s Great Red Spot or GRS is located in a ‘bay’ or hollow south of the swirly South Equatorial Belt. A titanic storm that’s raged like hurricane-like for at least 400 years, the top of the Spot’s cloud deck rises 5 miles (8 km) above the planet’s clouds and rotates in an anticlockwise direction about once every 4 days.

As to what causing the drastic downsizing, there are no firm answers yet:

“In our new observations it is apparent that very small eddies are feeding into the storm,” said Simon. “We hypothesized that these may be responsible for the accelerated change by altering the internal dynamics of the Great Red Spot.”

A brief primer on Jupiter’s Great Red Spot

The Great Red Spot has been a trademark of the planet for at least 400 years – a giant hurricane-like storm whirling in the planet’s upper cloud tops with a period of 6 days. But as it’s shrunk, its period has likewise grown shorter and now clocks in at about 4 days.

The storm appears to be conserving angular momentum by spinning faster the same way an ice skater spins up when she pulls in her arms. Wind speeds are increasing too, making one wonder whether they’ll ultimately shrink the spot further or bring about its rejuvenation.

Definitely worth keeping an eye on.
