NASAs new space station mission is not a big step toward Mars, but mostly a holding pattern

In late March astronaut Scott Kelly and cosmonaut Mikhail Kornienko will take off in a Soyuz rocket from the steppes of Kazakhstan, heading to the International Space Station (ISS) for a yearlong stay. NASA bills their mission as a crucial stepping-stone toward sending humans on a multiyear trip to Mars. That interplanetary voyage, part of our human drive for new frontiers, is the greatest dream of the space age. Yet rather than making that dream a reality, this mission seems to be a distracting detour. During their orbital sojourn Kelly and Kornienko will undergo rigorous medical testing designed to show researchers what long-term spaceflight does to human beings, particularly how prolonged weightlessness and radiation exposure cause harm. The results, NASA says, could lead to medical breakthroughs that make interplanetary hauls safer. Couldbut it likely wont make them safe enough. More likely, Kellys and Kornienkos tests will just confirm in greater detail what we already know from several previous long-duration missions: Our current space habitats are not adequate for voyages to other worlds. The lack of money to build these habitats, more than any lack of medical knowledge, is what keeps humans from Mars and other off-world destinations. For instance, we already know that living without gravity is a problem. Long periods of weightlessness atrophy muscles, weaken bones and worsen vision. Vigorous exercise can minimize some of these effects, so astronauts on the ISS spend hours each day working out. Even so, no matter how much they sweat in space, when Kelly and Kornienko return to Earth they will almost certainly be weaker than when they left. Investigators have known how to solve this problem since 1903, when Russian scientist Konstantin Tsiolkovsky described a spinning space habitat that would generate a force pulling away from the structures center and toward the outer edges, thereby mimicking gravity. This effect varies with the structures spin rate, creating any gravitational strength the structure can withstand, whether the comfortable one g of Earth or the languorous 0.38 g of Mars. (No one yet knows the optimum g-levels for healthy, affordable long-duration spaceflight, and Kellys and Kornienkos mission wont tell us.) Why doesnt NASA avail itself of this solution? Because it costs a lot, and the agency has already spent more than $75 billion on the weightless ISS. A rotating habitat would be more costly and complex than a weightless one (although it need not be a prohibitively pricey behemoth like the doughnut-shaped space station from 2001: A Space Odyssey). Two modules connected by a long spoke, set spinning by modest bursts from thruster rockets, could create artificial gravity at a more reasonable price, although this solution would still be more expensive than simply performing more medical tests in weightlessness. What NASA should be testing is how to build such a craft, and how to live and work within it without becoming disoriented and dizzy. As a starting point, a scaled-down centrifuge could be installed on the ISS to test how lab animals respond to varying levels of artificial gravity. The station was originally designed to include such a facility, the Centrifuge Accommodation Module. NASA, however, scuttled the project by removing it from ISS assembly flights during the shuttle era, in part due to budgetary concerns. Radiation, the other health threat in space, is a more pernicious danger. Showers of solar protons and galactic cosmic rays can rip through cells, wreaking biological havoc. The current remedy is to clad living quarters in layers of dense material, which adds weight and increases the amount of fuel needed to get off the ground. It doesnt have to be this way. Advanced space propulsion systems paired with cheaper rocket launches could allow properly shielded craft to make faster interplanetary trips, decreasing a crews overall radiation exposure. Such protection will be possible only if NASA rekindles and follows through on developing advanced solar- and nuclear-electric propulsion, efforts which have been started and canceled several times over the past half century. It would be unfair to blame NASA alone for this shortsightedness. Integrating artificial gravity and better propulsion into its human spaceflight program would require many billions of dollars, and that money is not forthcoming from Congress. So NASA has struck a pragmatic course, tinkering with well-worn technologies instead of spending the financial and political capital to develop new ones. This path of least resistance is not going to take us to Marsor on long-duration trips to the moon, asteroids or other deep-space destinations. NASA leadership should take a page from the playbook of Elon Musk and SpaceX and be bolder, pushing technologies for future exploration rather than relying on those from the past. If the American people do not feel that it is worth the money to take these next steps, the nation should face facts and abandon this dream of sending space travelers to worlds beyond our own.

A Waste of Space [Commentary]

Spacewalking astronauts successfully completed a three-day cable job outside the International Space Station on Sunday, routing several-hundred feet of power and data lines for new crew capsules commissioned by NASA.

It was the third spacewalk in just over a week for Americans Terry Virts and Butch Wilmore, and the quickest succession of spacewalks since NASA's former shuttle days.

The advance work was needed for the manned spacecraft under development by Boeing and SpaceX. A pair of docking ports will fly up later this year, followed by the capsules themselves, with astronauts aboard, in 2017.

Once safely back inside, Virts reported a bit of water in his helmet again for the second time in as many spacewalks. He stressed it was "not a big deal" and said there was no need to hurry out of his suit.

Virts and Wilmore installed two sets of antennas Sunday, as well as 400 feet of cable for this new communication system. They unreeled 364 feet of cable on Feb. 21 and last Wednesday.

It was complicated, hand-intensive work, yet the astronauts managed to wrap up more than an hour early Sunday, for a 5 -hour spacewalk. Their three outings spanned 19 hours.

"You guys have done an outstanding job," Mission Control radioed, "even for two shuttle pilots."

Sunday's 260-mile-high action unfolded 50 years to the month of the world's first spacewalk.

Soviet Alexei Leonov floated out into the vacuum of space on March 18, 1965, beating America's first spacewalker, Gemini 4's Edward White II, by just 2 1/2 months. Leonov is now 80; White died in the Apollo 1 fire on the launch pad in 1967.

"It's amazing ... to see how far we've come from the very first steps outside," Virts said.

Astronauts try to complete tricky cable repair outside space station

CAPE CANAVERAL, Fla. Spacewalking astronauts routed more than 300 feet of cable outside the International Space Station on Saturday, tricky and tiring advance work for the arrival of new American-made crew capsules.

It was the first of three spacewalks planned for NASA astronauts Butch Wilmore and Terry Virts over the coming week.

Altogether, Wilmore and Virts have 764 feet of cable to run outside the space station. They got off to a strong start Saturday, rigging eight power and data lines, or about 340 feet.

"Broadening my resume," Virts observed.

NASA considers this the most complicated cable-routing job in the 16-year history of the space station. Equally difficult will be running cable on the inside of the complex.

The extensive rewiring is needed to prepare for NASA's next phase 260 miles up: the 2017 arrival of the first commercial spacecraft capable of transporting astronauts to the orbiting lab.

NASA is paying Boeing and SpaceX to build the capsules and fly them from Cape Canaveral, which hasn't seen a manned launch since the shuttles retired in 2011. Instead, Russia is doing all the taxi work -- for a steep price.

The first of two docking ports for the Boeing and SpaceX vessels -- still under development -- is due to arrive in June. Even more spacewalks will be needed to set everything up.
