Please take the time to respectfully recognize the passing of veteran astronaut, Janice Voss. She was a former science director for a NASA exoplanet-hunting spacecraft and also a member of five manned spaceflights. She lost her battle with cancer today at the young age of 55. “Just got the very sad news that U.S. astronaut Janice Voss passed away last night,” the Association of Space Explorers, an international organization representing more than 350 individuals who have flown in space, wrote on Facebook. “Our thoughts go out to her family and friends.” NASA confirmed Voss’ passing in a statement issued on Tuesday (Feb. 7), saying she had passed away overnight.

Janice was born on October 8, 1956, in South Bend, Indiana, but she called Rockford, Illinois home. Some of her passions for life included flying, volleyball, dancing and reading science fiction. She graduated from from Minnechaug Regional High School, Wilbraham, Massachusetts, in 1972, continued on to Purdue University for her bachelor of science degree and achieved a master of science degree in electrical engineering and a doctorate in aeronautics/astronautics from the Massachusetts Institute of Technology in 1977 and 1987, respectively. From there, Janice continued her education by taking some correspondence courses from the University of Oklahoma and did some graduate work in space physics at Rice University in 1977 and 1978.

In 1990, Janice Voss was chosen by NASA for the astronaut corps and served as a mission specialist on five space shuttle missions, including the only repeat flight in the program’s 30 year history. But that’s not all. She also flew with the first commercial lab, rendezvoused with Russia’s Mir space station and helped create the most complete digital topographic map of the Earth. In June 1993, Janice took part in biomedical and material science experiments as a member of the Spacehab module – a commercial laboratory attached to the orbiter’s payload bay. In February 2000, Voss again launched on Endeavour as part of the Shuttle Radar Topography Mission crew. After deploying a nearly 200-foot (60-meter) mast, Voss and her team labored through two full shifts to map more than 47 million square miles (122 million square kilometers) of the Earth’s land surface. The shuttle Endeavour served as both her first and final mission.

The first time a space shuttle came close to the Russian Space Station, Mir, Dr. Voss was there. As her second mission, she and her STS-63 crew mates met with the Russians to discuss flight techniques, communications, sensors aids and navigation. The February 1995 “Near-Mir” mission set the stage for the first shuttle-Mir docking later that year. Janice also served on another historic mission – the only time a crew was launched twice to perform the same mission. The first launch came on April 4, 1997 and three days later it returned to Earth after a fuel cell problem. Ninty days later, the Columbia was restored and it launched again into a successful 15 day flight. This time Voss and crew engaged their time inside a European Spacelab module, conducting experiments as part of the Microgravity Science Laboratory (MSL) mission.

Over her career, astronaut Janice Voss totaled over 49 days in space, traveling 18.8 million miles (30.3 million km) while circling the Earth 779 times. Her five missions tied her with the record for the most spaceflights by a woman. When she at last touched down on Earth, she went on to the Johnson Space Center in Houston, Texas to NASA’s Ames Research Center at Moffett Field, California, where she headed the science program for the agency’s Kepler space observatory. She stayed at Ames until 2007 and spent the rest of her time as the payload lead in the astronaut office’s space station branch at the Johnson Space Center.

“As payload commander of two shuttle missions, Janice was responsible for paving the way for experiments that we now perform on a daily basis on the International Space Station,” chief astronaut Peggy Whitson said in a statement. “By improving the way scientists are able to analyze their data, and establishing the experimental methods and hardware necessary to perform these unique experiments, Janice and her crew ensured that our space station would be the site of discoveries that we haven’t even imagined.”

“During the last few years, Janice continued to lead our office’s efforts to provide the best possible procedures to crews operating experiments on the station today,” she said. “Even more than Janice’s professional contributions, we will miss her positive outlook on the world and her determination to make all things better.”

Godspeed, Janice… Godspeed.

Can Solar Flares Hurt Astronauts?

Solar flares, coronal mass ejections, high-energy photons, cosmic rays… space is full of various forms of radiation that a human wouldn’t want to be exposed to for very long. Energized particles traveling into and through the body can cause a host of nasty health problems, from low blood count to radiation sickness to cataracts and cancer… and potentially even death. Luckily Earth’s magnetic field and atmosphere protects us on the surface from much of this radiation, but what about the astronauts aboard the Space Station? How could events such as today’s powerful near-X-class solar flare and last week’s CME affect them, orbiting 240 miles above Earth’s surface?

Surprisingly, they are safer than you might think.

The M8.7-class flare that erupted from the Sun early on Jan. 23 sent a huge wave of high-energy protons Earthward, creating the largest solar storm seen since 2005.  The cloud of energetic particles raced outwards through the Sun’s atmosphere at speeds well over a million miles per hour, blowing past our planet later the same day. (More slower-moving charged particles will impact the magnetosphere in the coming days.) We are safe on Earth but astronauts exposed to such radiation could have faced serious health risks. Fortunately, most solar protons cannot pass through the hull of the Space Station and so as long as the astronauts stay inside, they are safe.

Of course, this is not the case with more dangerous cosmic rays.

According to the NASA Science site:

Cosmic rays are super-charged subatomic particles coming mainly from outside our solar system. Sources include exploding stars, black holes and other characters that dwarf the sun in violence. Unlike solar protons, which are relatively easy to stop with materials such as aluminum or plastic, cosmic rays cannot be completely stopped by any known shielding technology.

Even inside their ships, astronauts are exposed to a slow drizzle of cosmic rays coming right through the hull. The particles penetrate flesh, damaging tissue at the microscopic level. One possible side-effect is broken DNA, which can, over the course of time, cause cancer, cataracts and other maladies.

In a nutshell, cosmic rays are bad. Especially in large, long-term doses.

Now the astronauts aboard the ISS are still well within Earth’s protective magnetic field and so are shielded from much of the cosmic radiation that passes through our solar system daily. And, strangely enough, when solar flares occur – such as today’s – the amount of cosmic radiation the ISS encounters actually decreases.

Why?

The solar particles push them away.

Decrease in cosmic radiation during a CME recorded in 2005.

In an effect known as the “Forbush decrease”,  magnetically-charged particles ejected from the Sun during flares and CMEs reduce the amount of cosmic radiation the ISS experiences, basically because they “sweep away” other charged particles of more cosmic origin.

Because cosmic rays can easily penetrate the Station’s hull, and solar protons are much less able to, the irony is that astronauts are actually a degree safer during solar storms than they would be otherwise.

And it’s not just in low-Earth orbit, either: Wherever CMEs go, cosmic rays are deflected. Forbush decreases have been observed on Earth and in Earth orbit onboard Mir and the ISS. The Pioneer 10 and 11 and Voyager 1 and 2 spacecraft have experienced them, too, beyond the orbit of Neptune. (via NASA Science.)

Due to this unexpected side effect of solar activity it’s quite possible that future manned missions to the Moon, Mars, an asteroid, etc. would be scheduled during a period of solar maximum, like the one we are in the middle of right now. The added protection from cosmic rays would be a big benefit for long-duration missions since we really don’t know all the effects that cosmic radiation may have on the human body. We simply haven’t been traveling in space long enough. But the less exposure to radiation, the better it is for astronauts.

Maybe solar storms aren’t so bad after all.

NASA is Looking for a Few Good Astronauts — Like You?

Could this be you one day? Credit: NASA

NASA is looking for applicants for its next class of astronaut candidates who will support long-duration missions to the International Space Station and future deep space exploration activities.

“We hope to have a lot of interest and applications so we can have a great class in 2013,” Duane Ross of the NASA Astronaut Selection Office told Universe Today. “This is a pretty fun job.”

So, do you have the right stuff to be an astronaut in today’s changing space environment?

NASA says that a bachelor’s degree in engineering, science or math and three years of relevant professional experience are required in order to be considered. Typically, successful applicants have significant qualifications in engineering or science, or extensive experience flying high-performance jet-aircraft.

“For scientists, engineers and other professionals who have always dreamed of experiencing spaceflight, this is an exciting time to join the astronaut corps,” said Janet Kavandi, director of flight crew operations at the Johnson Space Center in Houston. “This next class will support missions to the station and will arrive via transportation systems now in development. They also will have the opportunity to participate in NASA’s continuing exploration programs that will include missions beyond low Earth orbit.”

Ross said that this upcoming class will be rather small. “The last class of 2009 we had nine NASA folks and they were joined by five international partner astronauts. I think our goal would be something in the eight to twelve range. The actual number doesn’t get decided until we know better what our requirements are and what our loses have been.”

So, how will these astronauts be trained, since the space shuttle is no longer flying and future astronauts may be flying on spacecraft that haven’t been built yet?

“For the last class we picked we actually picked them to be long duration crew members for space station. They didn’t train for the space shuttle and that is exactly what we are going to do with this class,” Ross said. “The new class will train for learning the International Space Station systems, the Russian language, spacewalk and robotics training, and several other disciplines and other things that will come online such as the MultiPurpose Crew Vehicle. For the things that mature downstream, there will be training for those when the time is right but right now we are going to concentrate on the space station.”

After applicant interviews and evaluations, NASA expects to announce the final selections in 2013, and training to begin that August.

NASA will begin accepting applications in November 2011. Additional information about the Astronaut Candidate Program is available by calling the Astronaut Selection Office at 281-483-5907.

Astronaut Mark Kelly, commander of the recent STS-134 shuttle mission and husband of Rep. Gabrielle Giffords, announced today via Facebook that he is retiring from NASA and the US Navy to spend time with his wife. Other sources say the two will write a memoir together.

“This was not an easy decision,” he wrote on his Facebook page. “Public service has been more than a job for me and my family. My parents are retired police officers. And my wife Gabrielle proudly serves in the U.S. House of Representatives.”

Kelly said that his decision to retire was not at all about questioning the future of NASA, but he feels a need to spend time with his wife and family.

“As life takes unexpected turns we frequently come to a crossroads,” Kelly wrote. “I am at this point today. Gabrielle is working hard every day on her mission of recovery. I want to be by her side. Stepping aside from my work in the Navy and at NASA will allow me to be with her and with my two daughters. I love them all very much and there is no doubt that we will move forward together. After some time off, I will look at new opportunities and am hopeful that one day I will again serve our country.”

Despite persistent rumors on the internet, Kelly has said he has no intentions of seeking public office and is “absolutely” convinced his wife will return to political life.

Rep. Giffords was shot in the head in January, 2011 in Tucson at an event she was hosting for residents of her Congressional district. Six people died and 13 were injured. She was recently released from a rehabilitation hospital in Houston.

Kelly’s retirement from NASA and the Navy, where he has served for 25 years, is effective Oct. 1. He has flown in space four times. According to ABC news, he and his wife said they have a deal with Scribner’s publishers for a joint memoir.

How does NASA Handle Delivering Tragic News?

Over the past decade, events have transpired on the ground that have both indirectly and directly impacted crews on orbit. With astronauts spending as long as six months in space on the International Space Station, some have had to deal with tragedies — both intimately personal and completely national — during a mission. NASA, for its part, has done everything it can do to prepare crews for life in space, and dealing with tragedies is factored into every flight.

When terrorists conducted the worst attack on American soil in U.S. history on September 11, 2001, there was a single U.S. astronaut orbiting high above on the ISS, left helpless to do anything but watch and photograph as his nation came under attack. Frank Culbertson, then commander of the orbiting outpost along with two Russian cosmonauts, spoke afterward of his sense of isolation as the country dealt with this tragedy.

A disaster a little closer to home struck on Feb. 1, 2003 – the space shuttle Columbia was lost on orbit with her crew of seven. Astronauts Donald Pettit and Kenneth Bowersox were on orbit on the ISS when Columbia broke apart in Earth’s atmosphere, returning from a non-space station mission. While the two crews were in space at the same time, astronauts Petit on the ISS and Willie McCool aboard Columbia played a friendly game of chess – separated by the void of space. Sadly, the game would never be finished. McCool and the rest of Columbia’s STS-107 lost their lives when the orbiter disintegrated in the skies above Texas. For Petit and Bowersox this cut them off from traditional forms of grieving as well as a way home.

With the orbiter fleet grounded, how would they change out crews? The 16 nations involved in the ISS project worked to balance things out until the shuttles were back in action. Post-Columbia, crew rotations among numerous other things would be changed. NASA would survive, but tragedies would still strike the NASA family.

When astronaut Dan Tani was stationed aboard the ISS in 2007 he received the terrible news that his mother was killed in an automobile accident. A NASA flight surgeon along with Tani’s wife contacted the astronaut while he was serving aboard the ISS.

With the recent tragedy in Tucson, Arizona, NASA once again had to focus on emergency contingencies. This time a commander for an upcoming shuttle mission, Mark Kelly, had to be notified that his wife, Rep. Gabrielle Giffords, had been seriously injured in a mass shooting while meeting with her constituents at an event called “Congress on your Corner.” NASA had to contact both Mark Kelly and his brother Scott, who was on-orbit aboard the ISS. NASA also had to deal with the potential that Mark might not be able to launch with his crewmates on Endeavour’s final mission – STS-134. As such, a backup commander was announced, four-time shuttle veteran Rick Sturckow.

“NASA’s goal is mission success and crew safety. Although NASA does not train crewmembers as backups for its shuttle crews or ISS crews, it has enough trained crewmembers that substitutions late in the training flow for medical or personal emergencies can succeed,” said Tom Jones Ph.D a four-time shuttle veteran and author of Sky Walking: An Astronaut’s Memoir. “NASA has replaced at least three crewmembers within a few months to launch since the Apollo era. They also moved an ISS crewmember in training to an earlier crew to replace a crewmember dealing with medical problems. Once in space, NASA will notify astronauts of family problems back on the ground if they have asked for such notification in discussions before launch.”

NASA works to ensure the safety and privacy of its astronauts during times like this. This point was emphasized during a recent press conference held to update the media about repairs conducted to the shuttle, Discovery. William Gerstenmaier; administrator for Space Operations stated emphatically from the outset – that this was not the appropriate time to discuss these issues. One wayward reporter tried anyway, taking the question at a different angle and to another member of the interview panel – John Shannon. Shannon made sure that the reporter understood and that NASA stood as one – behind Mark Kelly and his family.

There is no way that NASA can predict every single possible scenario – but the agency does the best it can.

“Crew members are informed as soon as possible of any family emergencies or other urgent news and issues. In advance of their mission, crew members meet with astronaut office management to discuss individual preferences regarding notification of such emergencies,” said Kylie Clem a public affairs officer with NASA. “NASA provides psychological support for all astronauts, including those in space. A NASA Flight Surgeon, psychological services and family support services are all available for Scott and Mark’s families. The astronaut office is a close knit organization.”

Not all the news NASA has relayed to its astronauts has been tragic. Astronaut Mike Fincke welcomed his daughter Tarali Paulina into the world from orbit in 2004 and astronaut Randy Bresnik did the same for his daughter, Abigail Mae Bresnik, while part of the STS-129 mission in 2009. In all cases, NASA works to ensure that, regardless of the situation, its astronauts will find out their most personal news – in the best way possible – given the circumstances.

STS-133 Astronaut Breaks Hip in Bicycle Accident

The crew of STS-133 has had to cope with the numerous technical issues and delays for their mission, related to both the Ground Umbilical Carrier Plate (GUCP) and to a larger extent the cracks that have cropped up on the shuttle’s external tank. Now they have a new issue to contend with – an injured crewmember.

Astronaut Tim Kopra was involved in a bicycle accident over the weekend and apparently broke his hip. Although NASA has not confirmed the injury, several news agencies have reported the news. More than likely, Kopra will not be able to fly with the rest of his crewmates when Discovery launches on her final mission, currently scheduled to liftoff on Feb. 24th. The accident took place on Jan. 15, leaving little over a month before the scheduled launch.

Kopra, 47, is part of a six member crew that will mark the final time that space shuttle Discovery will head to space. He was scheduled to be the primary spacewalker on the upcoming STS-133 mission, and is a U.S. Army colonel (retired). The spacewalks that NASA astronauts undertake take many months and in some cases years to prepare for.

Preliminary reports say that a backup astronaut has been chosen, but again, NASA has not confirmed the news. NASA does not routinely train backup astronauts for shuttle missions. UPDATE: NASASpaceflight.com is now reporting that astronaut Steven Bowen has been chosen as a replacement, and that the flight of STS-133 will proceed as scheduled.

UPDATE 2: NASA has confirmed Kopra’s injury and has announced that Bowen is the replacement for Kopra. “Tim is doing fine and expects a full recovery, however, he will not be able to support the launch window next month,” said Peggy Whitson, chief of the Astronaut Office at NASA’s Johnson Space Center in Houston. “If for some anticipated reason STS-133 slips significantly, it is possible that Tim could rejoin the crew.”

In a press release by NASA, Whitson added that Bowen is an ideal candidate to replace Kopra. “We have complete confidence he’ll contribute to a fully successful STS-133 mission. He has performed five prior spacewalks. That extensive experience, coupled with some adjustments to the spread of duties among the crew, will allow for all mission objectives to be accomplished as originally planned in the current launch window.”

Bowen will begin training this week with the STS-133 crew, which includes Commander Steve Lindsey, Pilot Eric Boe, and Mission Specialists Alvin Drew, Michael Barratt and Nicole Stott. Bowen also will train to perform the two planned spacewalks of the mission. He will join Alvin Drew to move a failed ammonia pump and perform other external configurations to the station.

STS-133 is scheduled to deliver the Leonardo Permanent Multipurpose Module (PMM). Contained within the PMM is the first humanoid robot to fly into space – Robonaut 2 (R2). Discovery will also transport much-needed spare parts to the orbiting laboratory.
