We often hear how the Moon’s appearance hasn’t changed in millions or even billions of years. While micrometeorites, cosmic rays and the solar wind slowly grind down lunar rocks, the Moon lacks erosional processes such as water, wind and lurching tectonic plates that can get the job done in a hurry.

Remember Buzz Aldrin’s photo of his boot print in the lunar regolith? It was thought the impression would last up to 2 million years. Now it seems that estimate may have to be revised based on photos taken by the Lunar Reconnaissance Orbiter (LRO) that reveal that impacts are transforming the surface much faster than previously thought.

The LRO’s high resolution camera, which can resolve features down to about 3 feet (1-meter) across, has been peering down at the Moon from orbit since 2009. Taking before and after images, called temporal pairs, scientists have identified 222 impact craters that formed over the past 7 years. The new craters range from 10 feet up to 141 feet (3-43 meters) in diameter.

By analyzing the number of new craters and their size, and the time between each temporal pair, a team of scientists from Arizona State University and Cornell estimated the current cratering rate on the Moon. The result, published in Nature this week, was unexpected: 33% more new craters with diameters of at least 30 feet (10 meters) were found than anticipated by previous cratering models.

their brightest recorded flash occurred on 17 March 2013 with coordinates 20.7135°N, 335.6698°E. Since then LRO passed over the flash site and the NAC imaged the surrounding area; a new 18 meter (59 feet) diameter crater was found by comparing images taken before and after the March date.

Similar to the crater that appeared on March 17, 2013 (above), the team also found that new impacts are surrounded by light and dark reflectance patterns related to material ejected during crater formation. Many of the larger impact craters show up to four distinct bright or dark reflectance zones. Nearest to the impact site, there are usually zone of both high and low reflectance.  These two zones likely formed as a layer of material that was ejected from the crater during the impact shot outward to about 2½ crater diameters from the rim.

From analyzing multiple impact sites, far flung ejecta patterns wrap around small obstacles like hills and crater rims, indicating the material was traveling nearly parallel to the ground. This kind of path is only possible if the material was ejected at very high speed around 10 miles per second or 36,000 miles per hour! The jet contains vaporized and molten rock that disturb the upper layer of lunar regolith, modifying its reflectance properties.


How LRO creates temporal pairs and scientists use them to discover changes on the moon’s surface.

In addition to discovering impact craters and their fascinating ejecta patterns, the scientists also observed a large number of small surface changes they call ‘splotches’ most likely caused by small, secondary impacts. Dense clusters of these splotches are found around new impact sites suggesting they may be secondary surface changes caused by material thrown out from a nearby primary impact. From 14,000 temporal pairs, the group identified over 47,000 splotches so far.

Based on estimates of size, depth and frequency of formation, the group estimated that the relentless churning caused by meteoroid impacts will turn over 99% of the lunar surface after about 81,000 years. Keep in mind, we’re talking about the upper regolith, not whole craters and mountain ranges. That’s more than 100 times faster than previous models that only took micrometeorites into account. Instead of millions of years for those astronaut boot prints and rover tracks to disappear, it now appears that they’ll be wiped clean in just tens of thousands!

Apollo 11 Landing 47 Years Ago; See it Through New Eyes

Looking for a way to commemorate the 47th anniversary of the Apollo 11 mission landing on the Moon? Here are a few different ways look back on this historic event and take advantage of advances in technology or new data.

Below is a video that uses data from the Lunar Reconnaissance Orbiter and its amazing suite of cameras, offering a side-by-side view of Apollo 11’s descent, comparing footage originally shot from the Eagle lunar module’s window with views created from reconstructed LRO imagery. This is a fun way to re-live the landing — 1202 alarms and all — while seeing high definition views of the lunar surface.

The National Air and Space Museum in Washington, DC has a special way to mark the Apollo 11 anniversary. They have posted online high-resolution 3-D scans of the command module Columbia, the spacecraft that carried astronauts Neil Armstrong, Buzz Aldrin and Michael Collins to the Moon. This very detailed model allows you to explore the entire spacecraft’s interior, which, if you’ve ever visited the Air & Space museum and seen Columbia in person, you probably know is a tremendous ‘upgrade,’ since you can only see a portion of the interior through couple of small hatches and windows. The Smithsonian is also making the data files of the model available for download so it can be 3-D printed or viewed with virtual-reality goggles. Find all the details here.

While 3D scanning the Apollo 11 Command Module, museum staff uncovered writing on the interior walls of the module.The main control panel of the spacecraft contains essential switches and indicators that had to be referred to and operated during the most crucial aspects of the flight. Numbers and references written by hand onto the panel can be checked against the audio and written transcripts from the mission to provide a more vivid picture of just what transpired.

Here’s a remastered version of the original mission video as aired in July 1969 depicting the Apollo 11 astronauts conducting several tasks during the moonwalk (EVA) operations on the surface of the moon, which lasted approximately 2.5 hours.

If you’re pressed for time, here’s a quick look at the entire Apollo 11 mission, all in just 100 seconds from Spacecraft Films:

Here’s a very cool detailed look at the Apollo 11 launch in ultra-slow motion, with narration:

Enjoy, and happy anniversary!

NASA Releases Strange ‘Music’ Heard By 1969 Astronauts

Calling it music is a stretch, but that’s exactly how the Apollo 10 astronauts described the creepy sounds they heard while swinging around the farside of the moon in May 1969. During the hour they spent alone cut off from communications with Earth, all three commented about a persistent “whistling” sound that lunar module pilot (LMP) likened to “outer-space-type-music”. Once the craft returned to the nearside, the mysterious sounds disappeared.


Apollo 10 Farside-of-the-Moon Music.

Hands down it was aliens! I wish. Several online stories fan the coals of innuendo and mystery with talk of hidden files and NASA cover-ups narrated to disturbing music. NASA agrees that the files were listed as ‘confidential’ in 1969 at the height of the Space Race, but the Apollo 10 mission transcripts and audio have been publicly available at the National Archives since 1973. Remember, there was no Internet back then. The audio files were only digitized and uploaded for easy access in 2012. Outside of the secretive ’60s, the files have been around a long time.

The story originally broke Sunday night in a show on the cable channel Discovery as part of the “NASA’s Unexplained Files” series; you’ll find their youtube video below. As I listen to the sound file, I hear two different tones. One is a loud, low buzz, the other a whooshing sound. My first thought was interference of some sort for the buzzing sound, but the whoosh reminded me of a whistler, a low frequency radio wave generated by lightning produced when energy from lightning travels out into Earth’s magnetic field from one hemisphere to another. Using an appropriate receiver, we can hear whistlers as descending, whistle-like tones lasting up to several seconds.

Lightning’s hardly likely on the Moon, and whistlers require a magnetic field, which the Moon also lacks. The cause turns out to be, well, man-made. Cernan’s take was that two separate VHF radios, one in the lunar module and the other in command module, were interfering with one another to produce the noise. This was later confirmed by Apollo 11 astronaut Mike Collins who flew around the lunar farside alone when Buzz Aldrin and Neil Armstrong walked on the Moon’s surface.

In his book Carrying the Fire, Collins writes: “There is a strange noise in my headset now, an eerie woo-woo sound.” He said it might have scared him had NASA’s radio technicians not forewarned him. The “music” played when the two craft were near one another with their radios turned on. Unlike Apollo 10, which never descended to the Moon’s surface but remained near the command module, the Apollo 11 lunar module touched down on the Moon on July 20, 1969. Once it did, Collins writes that the ‘woo-woo’ music stopped.

The astronauts never talked publicly or even with the agency about hearing weird sounds in space for good reason. Higher-ups at NASA might think them unfit for future missions for entertaining weird ideas, so they kept their thoughts private. This was the era of the “right stuff” and no astronaut wanted to jeopardize a chance to fly to the Moon let alone their career.


Outer Space Music Part 1 of NASA’s Unexplained Files —  to be taken with a boulder of salt

In the end, this “music of the the spheres” makes for a fascinating  tidbit of outer space history. There’s no question the astronauts were spooked, especially considering how eerie it must have felt to be out of touch with Earth on the far side of the Moon. But once the sounds stopped, they soldiered on — part of the grand human effort to touch another world.

“I don’t remember that incident exciting me enough to take it seriously,” Gene Cernan told NASA on Monday. “It was probably just radio interference. Had we thought it was something other than that we would have briefed everyone after the flight. We never gave it another thought.”

What Does it Take to Be an Astronaut?

What does it take to have the “Right Stuff” to become an Astronaut?

Are you an overachiever? Are you working on multiple PhDs in obscure and difficult topics? Can you speak multiple languages, including alienese? Do you suspect, if handed the controls, you could complete the Kessel Run in fewer parsecs than Han Solo?

If you said yes to any of these questions you might want to consider becoming an astronaut. In fact, if you’re an American citizen, there’s never been a better time to see if you’ve got the right stuff. NASA has opened up their astronaut corps to the few, the proud, the willing to get motion sickness in zero gravity. To boldly vomit where few have vomited before.

In the olden days, you either had to be a chimpanzee or an Air Force test pilot to be allowed to take the controls of a genuine NASA rocket and break free from the surly chains of gravity. When NASA finally upgraded its astronaut corps from chimps to humans in the 1950s to begin the Mercury program, they decided they’d only allow test pilots to apply for the first missions.

To fit in the cramped cabin, you had to physically be no taller than 180 cm (5’ 11”), and weigh no more than 82 kg (180 pounds). You needed to have book smarts, too. Astronaut candidates needed at least a bachelor’s degree or the equivalent, but still be under 40 years old. But most importantly, you had to be a test pilot with at least 1,500 hours of flying time and the ability to fly jets.

If you didn’t have hours behind the stick, piloting the most insane flying machines dreamt up by those nutty scientists, well then you didn’t have the right stuff.

Those qualifications continued through the Gemini and Apollo program, although, they relaxed them somewhat, allowing younger astronauts, and those with less flight time. In the recruitment of astronauts in 1965, they allowed a new class of scientist-astronauts; folks with science degrees and no flight time. The most famous of these was Jack Schmitt, a geologist who walked on the Moon with Apollo 17.

NASA now understands that they need astronauts with a wide range of space-based skills, and not just a bunch of test pilots. There are two kinds of people who get to go to space: pilots and mission specialists.

The first category are the commanders and pilot astronauts – the folks who actually fly the spacecraft. They’re the ones with thousands of hours behind the stick of a modern jet, the more cockamamie the better.

To be qualified as a pilot astronaut, you need to have at least 1,000 hours of pilot-in-command time in a jet aircraft. You need to be healthy, with normal blood pressure, good vision and a height between 158 – 191 cm (62 and 75 inches). There are no longer any age restrictions, so astronauts have been selected between 26 and 46 years old.

You need a degree in some kind of space-related science, like engineering, mathematics, biological science and physical science. But that’s a minimum. You really want to have an advanced degree, or even multiple degrees. So, if you’re a healthy, eagle-eyed test pilot with a few advanced degrees, you should apply.

The other category is the mission specialists. These are the astronauts with specialties that will come into play on a space mission. For example: doctors, engineers, particle physicists, xenobiologists, alien translators, droid mechanics, etc. Since you won’t be required to fly the spacecraft, test pilot experience isn’t necessary, but you’ll need to have the same physical health as the pilot astronaut.

The main difference is that you’ll need to have one or multiple advanced degrees in engineering, science or math. The more degrees, and the more advanced they are, the better. Gotta collect them all.

I mentioned two kinds of astronauts, but there’s actually a third – the payload specialist. These were the astronauts who went to space during the shuttle era to support a specific mission. Priority was given to qualified NASA astronauts, but this was also how foreign astronauts like Canada’s Marc Garneau got a chance to fly in space.

Are you intrigued and thinking you might want to throw your name in the helmet? Want to know what being an astronaut pays? A starting astronaut can make $66,000 per year, while a senior one can earn $145,000 per year. Not bad at all, and the view from your office is spectacular.

So, if you’re a US citizen, you meet the qualifications, and you’d like to fly to space, you should apply during this latest call for candidates. And if you don’t think you make the cut, go ahead and wrap up those PhDs, as there’ll be another astronaut selection in a few years.

And if you do apply and don’t make the cut this time around, don’t despair. From the astronauts I’ve talked to, sometimes it takes a few applications before you get accepted. Persistence pays off.

Well, are you going to sign up and become an astronaut? Where do you think your mission will go? Tell us in the comments below.

NASA’s Space Launch System Passes Critical Design Review, Drops Saturn V Color Motif

The SLS, America’s first human-rated heavy lift rocket intended to carry astronauts to deep space destinations since NASA’s Apollo moon landing era Saturn V, has passed a key design milestone known as the critical design review (CDR) thereby clearing the path to full scale fabrication.

NASA also confirmed they have dropped the Saturn V white color motif of the mammoth rocket in favor of burnt orange to reflect the natural color of the SLS boosters first stage cryogenic core. The agency also decided to add stripes to the huge solid rocket boosters.

NASA announced that the Space Launch System (SLS) has “completed all steps needed to clear a critical design review (CDR)” – meaning that the design of all the rockets components are technically acceptable and the agency can continue with full scale production towards achieving a maiden liftoff from the Kennedy Space Center in Florida in 2018.

“We’ve nailed down the design of SLS,” said Bill Hill, deputy associate administrator of NASA’s Exploration Systems Development Division, in a NASA statement.

Blastoff of the NASA’s first SLS heavy lift booster (SLS-1) carrying an unmanned test version of NASA’s Orion crew capsule is targeted for no later than November 2018.

Indeed the SLS will be the most powerful rocket the world has ever seen starting with its first liftoff. It will propel our astronauts on journey’s further into space than ever before.

SLS is “the first vehicle designed to meet the challenges of the journey to Mars and the first exploration class rocket since the Saturn V.”

Crews seated inside NASA’s Orion crew module bolted atop the SLS will rocket to deep space destinations including the Moon, asteroids and eventually the Red Planet.

“There have been challenges, and there will be more ahead, but this review gives us confidence that we are on the right track for the first flight of SLS and using it to extend permanent human presence into deep space,” Hill stated.

The core stage (first stage) of the SLS will be powered by four RS-25 engines and a pair of five-segment solid rocket boosters (SRBs) that will generate a combined 8.4 million pounds of liftoff thrust in its inaugural Block 1 configuration, with a minimum 70-metric-ton (77-ton) lift capability.

Overall the SLS Block 1 configuration will be some 10 percent more powerful than the Saturn V rockets that propelled astronauts to the Moon, including Neil Armstrong, the first human to walk on the Moon during Apollo 11 in July 1969.

The SLS core stage is derived from the huge External Tank (ET) that fueled NASA Space Shuttle’s for three decades. It is a longer version of the Shuttle ET.

NASA initially planned to paint the SLS core stage white, thereby making it resemble the Saturn V.

But since the natural manufacturing color of its insulation during fabrication is burnt orange, managers decided to keep it so and delete the white paint job.

“As part of the CDR, the program concluded the core stage of the rocket and Launch Vehicle Stage Adapter will remain orange, the natural color of the insulation that will cover those elements, instead of painted white,” said NASA.

There is good reason to scrap the white color motif because roughly 1000 pounds of paint can be saved by leaving the tank with its natural orange pigment.

This translates directly into another 1000 pounds of payload carrying capability to orbit.

“Not applying the paint will reduce the vehicle mass by potentially as much as 1,000 pounds, resulting in an increase in payload capacity, and additionally streamlines production processes,” Shannon Ridinger, NASA Public Affairs spokeswomen told Universe Today.

After the first two shuttle launches back in 1981, the ETs were also not painted white for the same reason – in order to carry more cargo to orbit.

“This is similar to what was done for the external tank for the space shuttle. The space shuttle was originally painted white for the first two flights and later a technical study found painting to be unnecessary,” Ridinger explained.

NASA said that the CDR was completed by the SLS team in July and the results were also further reviewed over several more months by a panel of outside experts and additionally by top NASA managers.

“The SLS Program completed the review in July, in conjunction with a separate review by the Standing Review Board, which is composed of seasoned experts from NASA and industry who are independent of the program. Throughout the course of 11 weeks, 13 teams – made up of senior engineers and aerospace experts across the agency and industry – reviewed more than 1,000 SLS documents and more than 150 GB of data as part of the comprehensive assessment process at NASA’s Marshall Space Flight Center in Huntsville, Alabama, where SLS is managed for the agency.”

“The Standing Review Board reviewed and assessed the program’s readiness and confirmed the technical effort is on track to complete system development and meet performance requirements on budget and on schedule.”

The final step of the SLS CDR was completed this month with another extremely thorough assessment by NASA’s Agency Program Management Council, led by NASA Associate Administrator Robert Lightfoot.

“This is a major step in the design and readiness of SLS,” said John Honeycutt, SLS program manager.

The CDR was the last of four reviews that examine SLS concepts and designs.

NASA says the next step “is design certification, which will take place in 2017 after manufacturing, integration and testing is complete. The design certification will compare the actual final product to the rocket’s design. The final review, the flight readiness review, will take place just prior to the 2018 flight readiness date.”

“Our team has worked extremely hard, and we are moving forward with building this rocket. We are qualifying hardware, building structural test articles, and making real progress,” Honeycutt elaborated.

Numerous individual components of the SLS core stage have already been built and their manufacture was part of the CDR assessment.

The SLS core stage is being built at NASA’s Michoud Assembly Facility in New Orleans. It stretches over 200 feet tall and is 27.6 feet in diameter and will carry cryogenic liquid hydrogen and liquid oxygen fuel for the rocket’s four RS-25 engines.

On Sept. 12, 2014, NASA Administrator Charles Bolden officially unveiled the world’s largest welder at Michoud, that will be used to construct the core stage, as I reported earlier during my on-site visit – here.

The first stage RS-25 engines have also completed their first round of hot firing tests. And the five segment solid rocket boosters has also been hot fired.

NASA decided that the SRBs will be painted with something like racing stripes.

“Stripes will be painted on the SRBs and we are still identifying the best process for putting them on the boosters; we have multiple options that have minimal impact to cost and payload capability, ” Ridinger stated.

With the successful completion of the CDR, the components of the first core stage can now proceed to assembly of the finished product and testing of the RS-25 engines and boosters can continue.

“We’ve successfully completed the first round of testing of the rocket’s engines and boosters, and all the major components for the first flight are now in production,” Hill explained.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center (KSC).

The SLS/Orion stack will roll out to pad 39B atop the Mobile Launcher now under construction – as detailed in my recent story and during visit around and to the top of the ML at KSC.

Relive Missions to the Moon with Fan Videos Created from NASA’s Apollo Archives

When NASA recently posted over 8,000 images from the Apollo missions on Flickr, I just knew something good was going to happen! There are so many creative people out there that just need a little spark, a little inspiration and they’re off creating wonderful things. Three videos so far have surfaced based on the imagery from NASA’s Apollo Archive.

The first comes from Tom Kucy who posted his video titled “Ground Control” on You Tube and said this is a “small personal project, bringing NASA’s Apollo Archive photos to life.” This video is like a 2.5 minute mini-documentary of the Apollo missions. Kucy uses stunning photos and audio from the Apollo missions to create a truly stunning video. As one commenter said, “This happened prior to my birth, and I truly feel like I was there. Nice, nice work!”

Kucy also added that he has the intention of bringing more missions life, so stay tuned for more.

The second video was created by harrisonicus on Vimeo, who said he was looking through the Project Apollo Archive and “at one point, I began clicking through a series of pics quickly and it looked like stop motion animation. So, I decided to see what that would look like without me having to click through it.”

It’s like a flipbook of the images, with music:

The original Apollo Archive website has been online since 1999 and was created by Kipp Teague as a companion website to his “Contact Light” site , a personal retrospective on Project Apollo. NASA now has posted the imagery on Flickr, giving them wider accessibility.

The third is a short gif video put together by planetary astronomer Alex Parker and posted on Twitter. He found new images of the damaged Apollo 13 Service Module, cleaned them up a bit and created this wonderful animation:

It’s a great new look at the service module, which was damaged when an oxygen tank in the module exploded. When the Apollo 13 crew jettisoned the crippled Service Module as they returned to Earth, they saw the extent of the damage from the explosion of the tank. “There’s one whole side of that spacecraft missing!” Jim Lovell radioed to Mission Control, his voice reflecting his incredulousness at seeing the damage of a 13-ft panel blown off the spacecraft.

You can read more about the damage on the SM in an article in our series on Apollo 13 here.

Below are a few of our favorite images from the collection that we’ve found so far. Enjoy, and make sure you check out all the images for yourself!

China aims to land a science probe and research rover on the far side of the Moon by 2020, say Chinese officials.

Chinese scientists plan to carry out the highly complex lunar landing mission using a near identical back up to the nations highly successful Chang’e-3 rover and lander – which touched down in December 2013.

If successful, China would become the first country to accomplish the history making task of a Lunar far side landing.

“The mission will be carried out by Chang’e-4, a backup probe for Chang’e-3, and is slated to be launched before 2020,” said Zou Yongliao from the moon exploration department under the Chinese Academy of Sciences, according to a recent report in China’s government owned Xinhua news agency.

Zou made the remarks at a deep-space exploration forum in China.

“China will be the first to complete the task if it is successful,” said Zou.

Chinese space scientists have been evaluating how best to utilize the Chang’e-4 hardware, built as a backup to Chang’e-3, ever since China’s successful inaugural soft landing on the Moon was accomplished by Chang’e-3 in December 2013 with the mothership lander and piggybacked Yutu lunar rover.

Plans to launch Chang’e-4 in 2016 were eventually abandoned in favor of further evaluation.

After completing an intense 12 month study ordered by China’s government, space officials confirmed that the lunar far side landing was the wisest use of the existing space hardware.

Chang’e-4 will be modified with a larger payload.

“Chang’e-4 is very similar to Chang’e-3 in structure but can handle more payload,” said Zou.

“It will be used to study the geological conditions of the dark side of the moon.”

The moon is tidally locked with the Earth so that only one side is ever visible. But that unique characteristic makes it highly attractive to scientists who have wanted to set up telescopes and other research experiments on the lunar far side for decades.

“The far side of the moon has a clean electromagnetic environment, which provides an ideal field for low frequency radio study. If we can can place a frequency spectrograph on the far side, we can fill a void,” Zou elaborated.

China will also have to launch another lunar orbiter in the next few years to enable the Chang’e-4 lander and rover to transmit signals and science data back to Chinese mission control on Earth.

In the meantime, China already announced its desire to forge ahead with an ambitious mission to return samples from the lunar surface later this decade.

The Chinese National Space Agency (CNSA) plans to launch the Chang’e-5 lunar sample return mission in 2017 as the third step in the nations far reaching lunar exploration program.

“Chang’e-5 will achieve several breakthroughs, including automatic sampling, ascending from the moon without a launch site and an unmanned docking 400,000 kilometers above the lunar surface,” said Li Chunlai, one of the main designers of the lunar probe ground application system, accoding to Xinhua.

The first step involved a pair of highly successful lunar orbiters named Chang’e-1 and Chang’e-2 which launched in 2007 and 2010.

The second step involved the hugely successful Chang’e-3 mothership lander and piggybacked Yutu moon rover which safely touched down on the Moon at Mare Imbrium (Sea of Rains) on Dec. 14, 2013 – marking China’s first successful spacecraft landing on an extraterrestrial body in history, and chronicled extensively in my reporting here at Universe Today.

Milestone Test Firing of NASA’s SLS Monster Rocket Engine Advances Human Path to Deep Space

During a 535-second test on August 13, 2015, operators ran the Space Launch System (SLS) RS-25 rocket engine through a series of tests at different power levels to collect engine performance data on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Credit: NASA

With today’s (Aug. 13) successful test firing of an RS-25 main stage engine for NASA’s Space Launch System (SLS) monster rocket currently under development, the program passed a key milestone advancing the agency on the path to propel astronauts back to deep space at the turn of the decade.

The 535 second long test firing of the RS-25 development engine was conducted on the A-1 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi – and ran for the planned full duration of nearly 9 minutes, matching the time they will fire during an actual SLS launch.

All indications are that the hot fire test apparently went off without a hitch, on first look.

“We ran the full duration and met all test objectives,” said Steve Wofford, SLS engine manager, on NASA TV following today’s’ test firing.

“There were no anomalies.” – based on the initial look.

The RS-25 is actually an upgraded version of former space shuttle main engines that were used with a 100% success rate during NASA’s three decade-long Space Shuttle program to propel the now retired shuttle orbiters to low Earth orbit. Those same engines are now being modified for use by the SLS.

“Data collected on performance of the engine at the various power levels will aid in adapting the former space shuttle engines to the new SLS vehicle mission requirements, including development of an all-new engine controller and software,” according to NASA officials .

The engine controller functions as the “brain” of the engine, which checks engine status, maintains communication between the vehicle and the engine and relays commands back and forth.

The core stage (first stage) of the SLS will be powered by four RS-25 engines and a pair of the five-segment solid rocket boosters that will generate a combined 8.4 million pounds of liftoff thrust, making it the most powerful rocket the world has ever seen.

Since shuttle orbiters were equipped with three space shuttle main engines, the use of four RS-25s on the SLS represents another significant change that also required many modifications being thoroughly evaluated as well.

The SLS will be some 10 percent more powerful than the Saturn V rockets that propelled astronauts to the Moon, including Neil Armstrong, the human to walk on the Moon during Apollo 11 in July 1969.

SLS will loft astronauts in the Orion capsule on missions back to the Moon by around 2021, to an asteroid around 2025 and then beyond on a ‘Journey to Mars’ in the 2030s – NASA’s overriding and agency wide goal.

Each of the RS-25’s engines generates some 500,000 pounds of thrust. They are fueled by cryogenic liquid hydrogen and liquid oxygen. For SLS they will be operating at 109% of power, compared to a routine usage of 104.5% during the shuttle era. They measure 14 feet tall and 8 feet in diameter.

They have to withstand and survive temperature extremes ranging from -423 degrees F to more than 6000 degrees F.

This video shows the full duration hot-fire test:

NASA has 16 of the RS-25s leftover from the shuttle era and they are all being modified and upgraded for use by the SLS rocket.

Today’s test was the sixth in a series of seven to qualify the modified engines to flight status. The engine ignited at 5:01 p.m. EDT and reached the full thrust level of 512,000 pounds within about 5 seconds.

The hot gas was exhausted out of the nozzle at 13 times the speed of sound.

Since the shuttle engines were designed and built over three decades ago, they are being modified where possible with state of the art components to enhance performance, functionality and ease of operation, by prime contractor Aerojet-Rocketdyne of Sacramento, California.

One of the key objectives of today’s engine firing and the entire hot fire series was to test the performance of a brand new engine controller assembled with modern manufacturing techniques.

“Operators on the A-1 Test Stand at Stennis are conducting the test series to qualify an all-new engine controller and put the upgraded former space shuttle main engines through the rigorous temperature and pressure conditions they will experience during a SLS mission,” says NASA.

“The new controller, or “brain,” for the engine, which monitors engine status and communicates between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine’s health and status.’

“The RS-25 is the most complicated rocket engine out there on the market, but that’s because it’s the Ferrari of rocket engines,” says Kathryn Crowe, RS-25 propulsion engineer.

“When you’re looking at designing a rocket engine, there are several different ways you can optimize it. You can optimize it through increasing its thrust, increasing the weight to thrust ratio, or increasing its overall efficiency and how it consumes your propellant. With this engine, they maximized all three.”

Engineers will now pour over the data collected from hundreds of data channels in great detail to thoroughly analyze the test results. They will incorporate any findings into future test firings of the RS-25s.

NASA says that testing of RS-25 flight engines is set to start later this fall.

“The RS-25 engine gives SLS a proven, high performance, affordable main propulsion system for deep space exploration. It is one of the most experienced large rocket engines in the world, with more than a million seconds of ground test and flight operations time.”

NASA plans to buy completely new sets of RS-25 engines from Aerojet-Rocketdyne taking full advantage of technological advances and modern manufacturing techniques as well as lessons learned from this hot fire series of engine tests.

The maiden test flight of the SLS is targeted for no later than November 2018 and will be configured in its initial 70-metric-ton (77-ton) version with a liftoff thrust of 8.4 million pounds. It will boost an unmanned Orion on an approximately three week long test flight beyond the Moon and back.

NASA plans to gradually upgrade the SLS to achieve an unprecedented lift capability of 130 metric tons (143 tons), enabling the more distant missions even farther into our solar system.

The first SLS test flight with the uncrewed Orion is called Exploration Mission-1 (EM-1) and will launch from Launch Complex 39-B at the Kennedy Space Center.

Answers:

1. James A. Lovell, Jr. Commander, John L. Swigert, Jr., Command Module Pilot, Fred W. Haise, Jr., Lunar Module Pilot.

2. Even though there were 7 Apollo missions that were supposed to land on the Moon with 2 astronauts walking on the Moon in each mission, , Apollo 13 never landed because of the accident. Read more about the explosion and why the timing of the accident was important to the crew’s survival here.

3. Fred Haise had been a newspaper stringer for a small newspaper in Mississippi when he was younger, taking notes and editing them for his local Mississippi paper’s stories. Utmost among reporters is accuracy in quoting sources. The transmitted words from Mission Control had to be flawlessly transcribed if the crew was to survive, and Haise did an amazing job. Read more about it in the article in the original “13 Things,” Charlie Duke’s Measles.

4. In the movie Apollo 13, Gene Kranz says the line, “Failure is not an option!” Even though Kranz never actually said those words during the “real” Apollo 13 mission, he liked the phrase so much that he used it for his autobiography. Who said it? Jerry Bostick, who was the Retrofire Officer and Flight Dynamics Officer in Mission Control during the Mercury, Gemini, Apollo and Skylab programs, said it during interviews for the Apollo 13 movie. Read more about the phrase and why they used it the movie here.

The statue of John L. "Jack" Swigert, Jr. is located in Emancipation Hall at the U.S. Capitol Visitor Center.
The statue of John L. “Jack” Swigert, Jr. is located in Emancipation Hall at the U.S. Capitol Visitor Center.

5. A statue of Jack Swigert is located in Emancipation Hall at the U.S. Capitol Visitor Center. Swigert was elected to Colorado’s Sixth Congressional District in 1982, but he died on December 27, 1982, before taking office. Read more about the Swigert and the statue here. Read more about the traits that made Swigert such a valuable crew member on Apollo 13 in “Charlie Duke’s Measles.

6. The longer than expected blackout period has never been fully explained, but several explanations have been offered. They include: the spacecraft coming in on a shallower trajectory that would result in a longer period in the upper atmosphere where there was less deceleration of the spacecraft and the communication signal skipping like a stone over layers of the upper atmosphere because of the shallow entry angle. Read more about the ‘shallow’ reentry and the communications blackout in our article here.

7. No one has fully explained why the hatch wouldn’t close immediately after the accident while it worked fine at reentry. It may have been because the two spacecraft (Command Module and Lunar Module) were skewed or twisted right after the explosion, but the position normalized later. Read more at the original series part 2, “The Hatch That Wouldn’t Close,” and part 8, “The Command Module Wasn’t Severed.

8. The Apollo 13 crew used things like watches, flashlights, pencils, pens and of course duct tape to help save the mission. Read more about them at “‘MacGyvering’ with Everyday Items” and “Duct Tape.”

9. The 1969 movie Marooned depicts three astronauts who survive an accident in space, but their lives hang in the balance as the people in Mission Control at NASA work night and day to figure out a way to bring the spacefarers home safely. Read how the movie inspired a NASA engineer to consider options for recharging the LM batteries in the original series part 11, “A Hollywood Movie.”

10. Jim Lovell took 2 trips to the Moon but never landed. He was on Apollo 8, which became the first human mission to orbit the Moon in 1968 and on Apollo 13, which didn’t land on the Moon because of the oxygen tank explosion in the Service Module.

11. Fred Haise got a kidney infection during the mission, possibly from not drinking enough water. Water was one of the resources that was scarce because of the inoperable fuel cells, which normally creates water as a byproduct of producing electrical power. Learn more about the Apollo era fuel cell at the Smithsonian Air & Space Museum.

12. The Saturn V 3rd stage (S-IVB) was part of a science experiment and was crashed into the Moon. The Apollo 12 mission had left a seismometer on the Moon, and an impact could produce seismic waves that could be registered for hours on the seismometer. This would help scientist to better understand the structure of the Moon’s deep interior. Find out more about the experiment and the communications problem caused by the 3rd stage at our article, “Detuning the Saturn V’s 3rd Stage Radio.

13. Mission duration 142 hours 54 minutes 41 seconds (or 5 days, 22 hours, 54 minutes, 41 seconds.) Read more about reentry at “The Mysterious Longer-Than-Expected Communications Blackout” and “The Trench Band of Brothers.”

Our thanks, once again, to NASA engineer Jerry Woodfill who originally came up with the ideas for the “13 Things” and “13 MORE Things That Saved Apollo 13.”

13 MORE Things That Saved Apollo 13, Epilogue: The ‘Failure is Not an Option’ Attitude

To celebrate the 45th anniversary of the Apollo 13 mission, Universe Today has been featuring “13 MORE Things That Saved Apollo 13,” discussing different turning points of the mission with NASA engineer Jerry Woodfill. Today, we let Jerry have the final word as he talks about a different aspect of the Apollo 13 mission.

Written By Jerry Woodfill:

I hesitated to include this among the “Things That Saved Apollo 13” because it is sort of intangible, i.e., not related to actual hardware, software, mission operations, and all things STEM. Nevertheless, in my mind, it is, perhaps, most responsible for the ultimate success of the rescue. I think it might override all the original “13 Things” as well as the “13 More Things that saved Apollo 13.”

Adding it came to me on New Year’s Eve of 2014. For a number of years, Apollo Flight Director Gene Kranz has presented a wonderful motivational program entitled and based on this concept, this motto, this creed — that failure is not an option. Five years ago, I borrowed the title for annual programs presented to high school and college students visiting the Johnson Space Center, such as in the picture above and below.

Universe Today writer Nancy Atkinson discussed in part 11 the origin of the saying “Failure is Not an Option,” which actually came from one of the “Trench” team members, Jerry Bostick.

Of course, there are those who consider the phrase “pie in the sky,” altogether “over-the-top” and “Pollyanna.” They assert that such is unrealistic when faced with obviously insurmountable challenges. For me, the best argument to counter that view came years ago from comments I’ve found on the internet. Below are a couple of paraphrased examples:

“Well… Apollo 13 has become my role model, my support, my comfort, and my favorite movie at 3 AM when I can’t sleep because I’m so overwhelmed with my own life. This is about how I use the movie as a crutch to get me through the day. This is about how Apollo 13 keeps me sane in an insane time!”

“They say that Apollo 13 was a Successful Failure because of all they learned from the experience. I’m hoping that my experience with cancer will also be a Successful Failure. The doctor has already told us that my dad won’t be cured, and any treatments we do won’t change that. So I already know that I’m going to be a failure. Nothing I do can save my father’s life. But maybe I can learn and grow. Just maybe my dad and I can have some more good times together. Maybe we can have some fun and overcome some challenges on this journey. Then I’d say it would be a successful failure for sure. Sometimes, I’m surprised at how my life seems to parallel the hardships the astronauts had to endure. I find myself doing things for my dad that I never imagined I would have to do.”

In like fashion, the heroism of Jim Lovell, Fred Haise, and Jack Swigert along with the resolve, perseverance, and herculean efforts of all involved would always be revered. “Failure Is Not an Option” is not naïve whatsoever. It is a guiding principle for whatever challenge we face.

I’ve also received emails, like the one below from people who have come across my off-the-job internet site:

Dear Mr. Woodfill:
I just watched the movie Apollo 13 and started researching the quote “failure is not an option”. In doing so I came across an article you had written, and I wanted to thank you for it.

I appreciated everything you wrote, but I was especially touched by the following: “I have to make sure that I do my best to make every day with my dad as wonderful as possible, that the end of his life is as good as it can be, and we learn something new every day we are together. I also need to remember that no matter how bad things get, I love my daddy and he loves me. If I just remember that… I can’t fail.”

Finding your article was such a blessing because today they just told me my father would have to go on hospice, and I have been praying to God for strength and peace for my father and for myself. After all, what could I possibly say or do that could help him? But after I read this I knew. I just have to love him. So thank you for that.

You wrote the article many years ago, and I know chances are small that you will ever receive this email. But I just wanted you to know how much peace I received from what you had written. Because, as you said, no matter how bad things get, if I just love him, I can’t fail.
Bless you for reminding me of that.
Sandra

Finally, Nancy asked me to explain how the phrase “Failure Is Not an Option” affected me. So how did that tagline affect me? Experiencing the “13 Things” and “the 13 More Things, at first in real time, and later in 100s of hours of reflection wholly changed the course of my life. I simply could not ignore the overwhelming evidence of so many things that saved Apollo 13 being fortuitous. In both series, I’ve done my best to “de-spiritualize” the accounts, knowing this series is a secular assessment. Actually, the genesis of every one of the now “26 things,” for me, was altogether providence or answered prayer. How this ensued is recorded on my off-the-job website if you are interested, as Paul Harvey used to say, in “the rest of the story.”

But I wanted to reach out to a much broader audience by sharing a factual secular account. I’m grateful to Nancy and “Universe Today” for making that possible.

In an off-hand way, many who have followed the series may have concluded what I discovered – that a person or power above had intervened as another of “the things that saved Apollo 13.” So I am always encouraged by the tagline “failure is not an option.” Now, it is, for me, another way of saying what I discovered through Apollo 13’s rescue that “all things work together for good,” as the above email says.

Thank you!
Sincerely,
Jerry Woodfill
