If there was a frequent flyer program for astronauts, Jerry Ross would be a gold status member. Ross is a veteran of seven space shuttle missions, making him a co-record holder for most spaceflights with fellow former NASA astronaut Franklin Chang-Diaz, and with nine spacewalks, he has the second most EVAs by a NASA astronaut. He is one of only three astronauts to have served throughout the entire Space Shuttle Program. Ross has written a new book about his life and career as an astronaut, “Spacewalker: My Journey in Space and Faith as NASA’s Record-Setting Frequent Flyer.” This is the first time he has told his story, reflecting on the legacy of the Shuttle program, its highs and lows, and the future of manned space flight.

Ross talked with Universe Today about his experiences and his new book. (Find out how you can win a copy of the book here.)

Universe Today: What made you decide to write a book about your experiences?

Jerry Ross: I wanted to share my experiences of what it was like to suit up to go out on a spacewalk and also help people understand what it is like to be an astronaut, that we are regular people who do regular work most of the time and only get to fly in space once in a while. In addition I wanted to entertain a little, use some funny stories that I had told many times to my friends when we were down at the Cape waiting for a launch, and a lot of times people would say, ‘those are great stories, you ought to write a book.’ After more and more people said that I started to take it a little more seriously.

Additionally I wrote it for my granddaughters who were young enough while I was still flying in space to not remember much, and in fact the youngest one was born after I had completed my flying. But probably the most important reason is that throughout my astronaut career I made a point that while I was talking with young students about their lives and what they could do with their God-given talents and capabilities, that they should dream large, study hard and work hard to reach their goals and not give up too easily. Throughout many of my talks over the years at schools, I have used my own career as a way of pointing out to them that, yeah, you are going to have some setbacks, your life won’t go in a straight line. You’ll have to study hard and work hard but you don’t have to be a straight-A student. And don’t give up too easily on what your goals are. I am one of the very fortunate ones who was able realize very early in my life what I wanted to do. I was able to set those goals and was able to achieve them, and what happened in my life was so much better than I could have dreamed about!

UT: You are obviously very dedicated to NASA. How does it feel to have the spaceflight records you have, and to have been a part the agency that is such an iconic part of America?

JR: The records are a byproduct of the what I said before; working hard and not giving up. I am and I was very dedicated to what our country was doing in space but I am somewhat frustrated that we are not doing more now. The records are quite frankly something that I wish I could have pushed much higher. I would have hoped to have flown many more times and done more spacewalks as well. Frankly, I’m disappointed that my records haven’t fallen and that those records aren’t continuing to be broken.

If we’re not continuing to push forward in space and do things more routinely and more aggressively, then as a country we are failing to be the leaders of the world that we should be in terms of leading humankind further into the Universe, learning more about the Universe and about ourselves, and potentially being able to live on other planets someday. While the records are nice — and it is kind of nice to put that in your bio that you hold the world record — it is not something that I hang onto, and like I said, I hope we will get back into a much more aggressive program that will push more people into space faster and farther.

UT: Do you have a favorite mission or favorite moment that you cherish from all your spaceflights?

JR: That question is just like asking a mother which one of her seven children she likes best! Every one of my flights was unique and different. All of them were a lot of fun with great crews and great missions. If I had to pick one, it would probably be the first flight, just because it was my first. It was an exciting mission, a great crew and I got to go on my first spacewalk, which laid the foundation for even more spacewalks in the future. At the time I launched I was already assigned to another mission, so it was a great time in my career when I was still fairly young but was really starting to feel the success of all the hard work.

UT: What was the most unexpected thing or experience you had?

JR: I think the most unexpected thing — and I talk about it in the book — is the epiphany I had on my fourth spacewalk on my third space shuttle mission when I was high above the payload on a foot restraint on the end of the robotic arm. The rest of the crew was concentrating on working with (astronaut) Jay Asp who was doing some work in the payload bay. I had the chance to look into deep space. It was at night and I turned off my helmet-mounted lights and just looked at the Universe and the uncountable number of stars out there. And all of a sudden I had this sense come over me — it was totally unexpected, it wasn’t something I was thinking about or contemplating — but it was a sense that I was doing what God had intended me to do, being in space in a spacesuit, working to fix satellites and assemble things in space. What a reassurance that you picked the right path, and that you are doing exactly what you were intended to do!

For an engineer to have any feelings at all, and especially a feeling like that traveling at 5 miles a second above the Earth is pretty incredible.

UT: I really enjoyed the sidebar pieces in the book that were written by the people important in your life – your friend Jim, and your wife and children. How did you decide to include that, and did you have any trouble convincing them to be a part of the book?

JR: The book started out with John Norberg, my co-writer, coming down and doing a series of interviews with me and also with my family members and my best friend Jim Gentleman, and one of my two sisters in Indiana. Initially, John was going to write more of the book than it ended up being. It was a much more collaborative effort than I had anticipated. But those sidebars or insights from others was totally his idea and one that I entirely latched onto once we started writing. I think it is a great insight into the rest of the family and how we operated as a family. I’ve had this comment multiple times now from folks that these additional insights were especially enjoyable.

UT: Your daughter Amy also works at NASA, and has helped to create better gloves for spacewalking. How gratifying is that to have her be a part of NASA?

JR: I think any parent is pleased if one of their children decides to follow in their footsteps. I guess that somehow validates that what the parent has been doing was something they valued and thought was interesting and exciting. Amy was exposed to it and was never encouraged one way or the other to be part of NASA or not, so it was very satisfying to see her do that. It was equally gratifying for me for my wife Karen to get into the space program working for United Space Alliance as one of the support contractors, and as you read in the book she helped supply the food for the shuttle and the station.

You also might be interested to know that Amy was interviewed for the astronaut program in January. For this selection process they had around 6,000 people who applied and they narrowed it down to about 400 that they deemed most qualified, and from that 400 they brought in 120, and she made that cut.

They will further reduce the number down to about 50 that will be brought back in for a second round of additional interviews and screenings, mostly some fairly heavy medical testing, and then from that they will select about 10 or so in the middle of the year. So we are extremely excited for her and keeping our fingers crossed.

UT: You write in detail about the two shuttle accidents. How difficult were those two periods of time – both personally and for everyone in the astronaut office?

JR: It was a tremendous loss. The astronaut office is relatively small. At the time of those losses, we were in the neighborhood of about 100 people total, and you get to know folks pretty well. To have your friends doing what we all enjoyed and seeing them be lost and then learning that probably, had we been smarter or more diligent, we as an agency could have prevented both of those accidents. That is very hurtful.

You go through a lot of soul searching, especially after the Challenger accident when we were still very early in the shuttle program to lose a vehicle and friends that way. My family was still quite young and it makes you really do some soul searching about whether or not you should continue to do that and put your life and therefore your family at risk. We talked about it quite a bit as a family and fortunately we all agreed that it would be letting our friends down if we decided to pull out and go do something else.

UT: You mentioned this earlier, and you don’t mince words in the book about your disappointment with the direction NASA is going. Have your thoughts changed any about the SLS?

JR: No, I still think that the agency is wandering in the forest. Most of the direction that we are getting from Congress is the direction that reinstituted the SLS and is pushing Orion forward. The administration is really pushing the commercial space aspect, and it still makes me very nervous that the commercial space guys may not pan out. It makes me nervous that NASA won’t have more control and insight on what is going on with the vehicles, from both a safety and operational perspective. It makes me nervous that we are planning to rely up on them solely to get to and from low Earth orbit, when in fact if they have an accident either with one of our crews or theirs, it could precipitate a lawsuit, which might put them into bankruptcy. Where would we be then?

So there are lots of reasons why I don’t think this is the right answer. I totally agree with commercial space if they want to go spend their own nickel and go do things, that is fine. As a government agency I think we should provide all the help and assistance that we can, but at the same time I don’t think we should be diverting resources of NASA’s programs to be paying for theirs. And that is what we are doing right now.

If we had not stopped the Constellation program, we would be in the process of getting ready to go launch an Orion right now. So what we are doing is delaying progress for the nation and what is going to happen in respect to commercial space is not at all certain. I frankly do not see any business model that would keep any of those commercial systems operating without a great underwriting and usage by NASA. And so I don’t see the logic in what is going on.

UT: Your faith is obviously very important to you, and I recall the one line you wrote, that you find it impossible to believe that everything you saw from space was created without God. In some circles, it seems to be that it is either science or religion that the two are hard to mix. But you obviously have no problem mixing the two in your life.

JR: Absolutely. I have had no problems along those lines whatsoever. I think the problems come when people try to read too literally passages in the Bible, and to not to just accept God on faith. So, somehow I think people try to limit God by reading an exact passage in the Bible, in a certain kind of Bible, when in fact the passage would read quite differently depending on what kind of Bible you are reading.

UT: Is there anything else that you feel is important for people to know about your book or your experiences in general?

JR: I hope people will read the book and enjoy it, number one! Secondly I hope they will get a better understanding of what it takes to make a spaceflight happen. But probably the most important thing is that I hope that it might help young adults and school age children interested in science and engineering. But the main emphasis of the book is to set goals for yourself, study hard, work hard and don’t give up too easily.

UT: Jerry, its been an honor to talk with you! Thank you very much.

JR: I’ve enjoyed it, thank you!

From One Laurel to Another: a Letter from Columbia

STS-107 Mission Specialist Laurel B. Clark (NASA)

On this Day of Remembrance, February 1, 2013, NASA will mark the 10th anniversary of the STS-107 Columbia accident with a wreath-laying ceremony at the astronaut memorial in Arlington National Cemetery, paying tribute to the lost crews of Columbia, Challenger and Apollo 1, as well as other space explorers and NASA colleagues who have passed on. Most of us have our own personal memories of the tragic events that took the lives of these brave few who risked everything in the name of exploration, knowledge, and discovery, and I’ve agreed to share one person’s connection to the Columbia crew.

Laurel Nendza, a fellow space blogger over on that social media site that begins with F and rhymes with “acebook” has a particular connection with STS-107 Mission Specialist Laurel B. Clark… if only that they both love space and share the same first name. Still, it’s enough to hang one’s heart on, and Laurel (the blogger) recently posted a particularly touching note that was sent by Laurel (the astronaut) to her family just before Columbia headed back on its ill-fated return trip home. Here’s Laurel’s (and Laurel’s) story:

On February 1, 2003, the seven [STS-107] crew members were lost with the Space Shuttle Columbia over North Texas during the shuttle’s re-entry. They were brave men and women who gave their lives for space exploration.

s107e05167One member has always stood out to me. Her name was Laurel Clark. She would probably agree that growing up there were never any other Laurels around. She may at one time hated her name like I did, only to realize she was actually cool and unique because she was the only one around with that name. But Laurel is not just a name, it’s a personality trait. I know a handful of Laurels (mostly from Facebook) and we all seem to have the same things in common. Most of us always have had deep compassion for animals, the Earth, and the sky above us. Laurel Clark was no different.

What was different about Laurel Clark is that she was just a handful of people on Earth, EVER, who actually achieved what we all dream. She was an astronaut and got to go to outer space. She had the privilege (that she worked very hard to get) to witness our pale blue dot from above as well as breathtaking auroras, lightning, and the Sun and Moon rising.

Before she departed to her last shuttle flight home she sent an email to her family and close friends. She told them of every incredible, awe-inspiring moment she had been a part of. She and the other 6 members who perished in the Columbia tragedy are true heroes and inspirations to all who came after her. They are my inspiration. My dream is to also be able to see my beautiful planet from above, and to see the stars shine bright in all their glory.

s107e05006She was the first Laurel in space, who knows? Maybe one day I will be the next?

Rest in peace all the brave crew of the Shuttle Columbia.

Below is Laurel Clark’s last message to her loved ones on Earth:

“Hello from above our magnificent planet Earth. The perspective is truly awe-inspiring. This is a terrific mission and we are very busy doing science round the clock. Just getting a moment to type e-mail is precious so this will be short, and distributed to many who I know and love.

I have seen some incredible sights: lightning spreading over the Pacific, the Aurora Australis lighting up the entire visible horizon with the cityglow of Australia below, the crescent moon setting over the limb of the Earth, the vast plains of Africa and the dunes on Cape Horn, rivers breaking through tall mountain passes, the scars of humanity, the continuous line of life extending from North America, through Central America and into South America, a crescent moon setting over the limb of our blue planet. Mount Fuji looks life a small bump from up here, but it does stand out as a very distinct landmark.

Magically, the very first day we flew over Lake Michigan and I saw Wind Point (Wisconsin) clearly. Haven’t been so lucky since. Every orbit we go over a slightly different part of the Earth. Of course, much of the time I’m working back in Spacehab and don’t see any of it. Whenever I do get to look out, it is glorious. Even the stars have a special brightness.

I have seen my ‘friend’ Orion several times. Taking photos of the earth is a real challenge, but a steep learning curve. I think I have finally gotten some beautiful shots the last 2 days. Keeping my fingers crossed that they’re in sharp focus.

My near vision has gotten a little worse up here so you may have seen pics/video of me wearing glasses. I feel blessed to be here representing our country and carrying out the research of scientists around the world. All of the experiments have accomplished most of their goals despite the inevitable hiccups that occur when such a complicated undertaking is undertaken. Some experiments have even done extra science. A few are finished and one is just getting started today.

The food is great and I am feeling very comfortable in this new, totally different environment. It still takes a while to eat as gravity doesn’t help pull food down your oesophagus. It is also a constant challenge to stay adequately hydrated. Since our body fluids are shifted toward our heads our sense of thirst is almost non-existent.

Thanks to many of you who have supported me and my adventures throughout the years. This was definitely one to beat all. I hope you could feel the positive energy that beamed to the whole planet as we glided over our shared planet.

Love to all, Laurel.”

Airing on PBS stations in the US tonight (January 31, 2013) a new film in conjunction with the 10th anniversary of the space shuttle Columbia disaster. Space Shuttle Columbia: Mission of Hope tells the little-known story of Columbia astronaut Ilan Ramon from Israel, the son of Holocaust survivors who became Israel’s first astronaut. Ramon carried into space a miniature Torah scroll that had survived the horrors of the Holocaust, given to a boy in a secret bar mitzvah observed in the pre-dawn hours in the notorious Nazi concentration camp of Bergen-Belsen.

“Moving tributes like this film remind us all that spaceflight always carries great risk,” said NASA Administrator and four-time space shuttle astronaut Charles Bolden. “But fallen heroes like Ilan were willing to risk the ultimate sacrifice to make important science discoveries and push the envelope of human achievement.”

See the trailer, below:

The film premieres tonight at 9:00 p.m. EST (check local listings here) on PBS stations. It will be followed by an encore broadcast of NOVA “Space Shuttle Disaster” at 10:00 p.m. EST, which examines the causes of the tragedy.

Most PBS specials are rebroadcast and are usually available later on the internet, and so check your local listings if you missed it, and we’ll also post a link if/when this film becomes available online.

Book Review: Unraveling the Universe’s Mysteries

“Unraveling the Universe’s Mysteries” is Louis A. Del Monte’s contribution to the world of science writing. If you haven’t heard of him, don’t be surprised. He’s not a prolific author or researcher, but worked in the development of microelectronics for the US companies IBM and Honeywell before forming a high-tech e-marketing agency.

The book lives up to its title and long subtitle: “Explore sciences’ most baffling mysteries, including the Big Bang’s origin, time travel, dark energy, humankind’s fate, and more.” It covers string theory, the Big Bang, dark matter, dark energy, time travel, the existence of God, and other mysterious aspects of our Universe. Del Monte also discusses artificial intelligence, the end of the Universe, and the mysterious nature of light. These subjects have all been covered in great detail by other authors in other books. How does Del Monte’s treatment of these subjects stand up in comparison?


Not great, in my opinion. The writing is somehow uninviting. The book reads more like a textbook or a lecture than it does a science book for an interested audience. It’s somewhat dry, and the writing is kind of heavy. After looking into Del Monte’s background, it becomes clear why. He’s an engineer, and his background is in writing technical papers.

This book is a bit of a puzzle, as is the author himself. I’ve mentioned the problems with the writing, but there are other issues. In one instance Del Monte references a study from the Journal of Cosmology. If you haven’t heard of that journal, it’s come under heavy criticism for its peer-review process, and isn’t highly regarded in science circles. The Journal of Cosmology seems to be a journal for people with an axe to grind around certain issues more than a healthy part of the science journal community. To be quoting studies from it is a bit of a black mark, in my opinion.

In another instance, he opens the chapter on Advanced Aliens with a quote from “Chariot of the Gods”, that old book/documentary from the 1970’s that just won’t seem to die, no matter how discredited it is. The main thrust of “Chariot of the Gods” is that human civilisation got a technological boost from visitations by advanced aliens. Readers can judge for themselves the wisdom of quoting “Chariot of the Gods” in a science book.

The publisher bills the book as “a new theory to explain one of cosmology’s most profound mysteries, the accelerated expansion of the universe,” and that Del Monte “presents an original solution to Einstein’s equations of special relativity.” But without conducting peer reviewed research, the validity of his theory comes into question.

If I seem puzzled by this book, it’s because I am. Del Monte seems to be a bit of an outsider when it comes to writing about astronomy and cosmology. He has no background in it. There’s nothing wrong with that in principle; there’s always room for new perspectives in science. But I can’t help thinking that he could’ve benefited from working more closely with an experienced editor.

Readers will get something out of this book; it’s an interesting discussion of the mysterious aspects of our Universe. But it’s also a somewhat strange book. For those of you who decide to read it, you’re in for an interesting read.

First Color Image of Curiosity’s Tracks from Orbit

As Curiosity prepares for the historic first drilling operation on Mars, the HiRISE camera aboard the Mars Reconnaissance Orbiter captured an image of it from 271 km (169 miles) up, along with twin lines of tracks and the blast marks from the dramatic rocket-powered descent back on August 6 (UTC).

The image here was acquired on Jan. 13, Sol 157 of the MSL mission, as part of a dual HiRISE/CRISM observation of the landing site. According to The University of Arizona’s HiRISE site it’s the first time the rover’s tracks have been imaged in color.

Her original landing site can be seen at the right edge. (Wait… did I just say “her?”)

The pair of bright white spots in the HiRISE image show the area immediately below where sky crane’s rockets were pointed. Those areas were “blasted clean” and therefore show brightest. The larger dark scour zone is dark because the fine dust has been blown away from the area leaving darker materials.

Curiosity can be seen as she (yes, it was confirmed today during ScienceOnline2013 that the rover — like all exploration vehicles — is a girl) was preparing for drilling into a rock outcrop called John Klein within the “Yellowknife” region in Gale Crater. Drilling is expected to begin today, Jan. 31.

The long awaited and history making first use of a drill on Mars is set to happen on Thursday, Jan. 31, 2013, or Sol 174, by NASA’s Curiosity Mars Science Lab (MSL) rover, if all goes well, according to science team member Ken Herkenhoff of the USGS.

Curiosity’s first drilling operation entails hammering a test hole into a flat rock at the location where the rover is currently parked at a scientifically interesting outcrop of rocks with veined minerals called ‘John Klein’. See our mosaics above & below illustrating Curiosity’s current location.

“Drill tailings will not be collected during this test, which will use only the percussion (not rotation) drilling mode,” says Herkenhoff.

Curiosity is an incredibly complex robot that the team is still learning to operate. So the plan could change at a moment’s notice.

The actual delivery of drill tailings to Curiosity’s CheMin and SAM analytical labs is still at least several days or more away and must await a review of results from the test drill hole and further drilling tests.

“We are proceeding with caution in the approach to Curiosity’s first drilling,” said Daniel Limonadi, the lead systems engineer for Curiosity’s surface sampling and science system at NASA’s Jet Propulsion Laboratory (JPL). “This is challenging. It will be the first time any robot has drilled into a rock to collect a sample on Mars.”

On Sol 166, Curiosity drove about 3.5 meters to reach the John Klein outcrop that the team chose as the 1st drilling site. The car sized rover is investigating a shallow depression known as ‘Yellowknife Bay’ – where she has found widespread evidence for repeated episodes of the ancient flow of liquid water near her landing site inside Gale Crater on Mars.

In anticipation of Thursday’s planned drilling operation, the rover just carried out a series of four ‘pre-load’ tests on Monday (Jan. 27), whereby the rover placed the drill bit onto Martian surface targets at the John Klein outcrop and pressed down on the drill with the robotic arm. Engineers then checked the data to see whether the force applied matched predictions.

“The arm was left pressed against one of them overnight, to see how the pressure changed with temperature,’ says Herkenhoff.

Because huge temperature swings occur on Mars every day (over 65 C or 115 F), the team needs to determine whether there is any chance of excessive stress on the arm while it is pressing the drill down onto the Martian surface. The daily temperature variations can cause rover systems like the arm, chassis and mobility system to expand and contact by about a tenth of an inch (about 2.4 millimeters), a little more than the thickness of a U.S. quarter-dollar coin.

“We don’t plan on leaving the drill in a rock overnight once we start drilling, but in case that happens, it is important to know what to expect in terms of stress on the hardware,” said Limonadi. “This test is done at lower pre-load values than we plan to use during drilling, to let us learn about the temperature effects without putting the hardware at risk.”

The high resolution MAHLI microscopic imager on the arm turret will take close-up before and after images of the outcrop target to assess the success of the drilling operation.

On Sol 175, another significant activity is planned whereby one of the ‘blank” organic check samples brought from Earth will be delivered to the SAM instrument for analysis as a way to check for any traces of terrestrial contamination of organic molecules and whether the sample handing system was successfully cleansed earlier in the mission at the Rocknest windblown sand ripple.

Meanwhile on the opposite side of Mars, NASA’s Opportunity rover starts Year 10 investigating never before touched phyllosilicate clay minerals that formed eons ago in flowing liquid water at Endeavour crater – detailed here.

Stay tuned for exciting results from NASA’s Martian sisters.

Watch a Magical Moonrise

This is absolutely lovely. Photographer Mark Gee says this incredible real-time video “is as it came off the memory card and there has been no manipulation whatsoever.” It shows the full Moon rising over the Mount Victoria Lookout in Wellington, New Zealand.

“People had gathered up there this night to get the best view possible of the moon rising,” Gee wrote on Vimeo. “I captured the video from 2.1km away on the other side of the city. It’s something that I’ve been wanting to photograph for a long time now, and a lot of planning and failed attempts had taken place. Finally, during moon rise on the 28th January 2013, everything fell into place and I got my footage.”

While Gee said it was a challenge to shoot, the final result is stunning.

NASA’s Tracking and Data Relay Satellite System will get an upgrade as the first of a new generation of communications satellites was launched to orbit on Wednesday, January 30 at 8:48 p.m. EST from Cape Canaveral. See the launch video and more images of the launch, below.

The TDRS system provides a critical communications link to Earth for the International Space Station, the Hubble Space Telescope and many satellites.

“TDRS-K bolsters our network of satellites that provides essential communications to support space exploration,” said Badri Younes, deputy associate administrator for Space Communications and Navigation at NASA. “It will improve the overall health and longevity of our system.”

The TDRS system provides tracking, telemetry, command and high-bandwidth data return services for numerous science and human exploration missions orbiting Earth. These include the International Space Station and NASA’s Hubble Space Telescope.

“With this launch, NASA has begun the replenishment of our aging space network,” said Jeffrey Gramling, TDRS project manager. “This addition to our current fleet of seven will provide even greater capabilities to a network that has become key to enabling many of NASA’s scientific discoveries.”

TDRS-K was launched on a United Launch Alliance Atlas V rocket from Space Launch Complex-41. After a three-month test phase, NASA will accept the spacecraft for additional evaluation before putting the satellite into service.

The TDRS-K spacecraft includes several modifications from older satellites in the TDRS system, including redesigned telecommunications payload electronics and a high-performance solar panel designed for more spacecraft power to meet growing S-band requirements. Another significant design change, the return to ground-based processing of data, will allow the system to service more customers with evolving communication requirements.

The next TDRS spacecraft, TDRS-L, is scheduled for launch in 2014. TDRS-M’s manufacturing process will be completed in 2015.

The Cost of Exploring Space: Film vs. Reality

We all know that space exploration, while certainly not the largest expenditure of most countries, doesn’t come cheap. But neither do big-budget science fiction films, either. Special effects, sets, special effects, popular acting talent… special effects… those all come with hefty price tags that make sci-fi and fantasy films costly ventures — although bigger definitely isn’t always better. If you were to compare the price of real space exploration missions (which provide actual information) to the costs of movies about space exploration (which provide “only” entertainment) what would you expect to find?

This infographic does just that:

“Prometheus’ movie budget would be enough to keep the search for real aliens going for another 52 years.”

Wow. (Maybe they should have just written a check to SETI.)

Kepler Spacecraft Back in Action After Reaction Wheel Problem

There has been some concern about the Kepler spacecraft after one of the devices that provide the ability for super-precise pointing began misbehaving. Reaction wheels are devices which aim a spacecraft in different directions without firing rockets or jets, which reduces the amount of fuel a spacecraft needs; Kepler has four of them. Earlier this year, elevated friction was detected in reaction wheel #4, and so as a precaution for wheel safety, and as a measure to mitigate the friction, the reaction wheels were spun down to zero-speed and the spacecraft was placed in a thruster-controlled safe mode.

But now after a “rest” of the wheels for ten days, Kepler has now returned to science data collection beginning on January 28, 2013, and reaction wheel #4 seems to be operating normally, for now. During the 10-day resting safe mode, daily health and status checks with the spacecraft using NASA’s Deep Space Network were normal.

This is of special concern because last year, reaction wheel #2 failed. Kepler scientists say the spacecraft needs at least three wheels must operate until at least 2016 for Kepler to achieve its prime objective of finding Earth-like planets around sun-like stars. Last year, NASA approved an extended mission for Kepler through 2016, and so a lot is riding on the health of the spacecraft’s reaction wheels.

During much of the mission, ground controllers have observed intermittent friction on wheel # 4. Wheel # 2, on the other hand, showed no problems until early 2012, and it failed several months later.

“Since the failure of reaction wheel #2 in July 2012, the performance of the spacecraft on three wheels has been excellent,” said Kepler Project Manager Roger Hunter, writing an update on the Kepler website, noting that when reaction wheel #2 began to fail, it also exhibited elevated and somewhat chaotic friction.

“Reaction wheel #4 has been something of a free spirit since launch, with a variety of friction signatures, none of which look like reaction wheel #2, and all of which disappeared on their own after a time,” Hunter said. “Resting the wheels can provide an opportunity for the lubricant in the bearings to redistribute and potentially return the friction to nominal levels. Over the next month, the engineering team will review the performance of reaction wheel #4 before, during, and after the safe mode to determine the efficacy of the rest operation.”

As Emily Lakdawalla noted in one of the Weekly Space Hangouts, engineers are getting creative in how to deal with hardware issues in spacecraft, and compared the Kepler team’s approach to “resting” the reaction wheel to how engineers working with the Spirit Mars rover came up with the plan to have the rover drive backwards when one of the wheels started acting up, and the lubricant lasted longer when the wheel was used in the opposite direction.

Engineers for Kepler have implemented additional procedures to extend the lives of the reaction wheels, including running the wheels at warmer temperatures and alternating their spin directions.

Kepler was launched in March 2009, and is in an Earth-trailing solar orbit. It is pointed toward constellations Cygnus and Lyra, observing a 10-degree-wide field containing at least 4.5 million stars. Kepler is focusing on approximately 156,000 stars for the purposes of its research. Kepler scientists have found 105 new planets around other stars, and the mission’s data archive has evidence for more than 2,700 planet candidates.
