After 15 years, it’s time to remodel space station

Today marks the 15th anniversary of that first moving-in day for spacefliers living on the International Space Station – and like many places that have been lived in for 15 years, the ISS is in the midst of renovations.

This isn’t your typical “reno,” however: There’s no other place where the doors have to be replaced while the construction site is moving at 18,000 mph, 225 miles above Earth’s surface. That’s basically what’s involved in getting the station ready for the arrival of Boeing and SpaceX crew transport ships in the 2017 time frame.

“To implement it on orbit is extremely complex, and must be orchestrated very carefully,” John Vollmer, Boeing’s chief engineer for the space station project, says in a video marking the anniversary. Boeing is the prime contractor for the station’s U.S. segment.

Three future frontiers for Seattle space ventures

What is it about Seattle that’s led some folks to call it the “Silicon Valley of space,”and how far can space entrepreneurs go in the next 20 years? One of the panels at Friday’s Xconomy Seattle 2035 conference tackled those questions – and added a couple of shorter-term predictions as well.

Jason Andrews, the CEO of Seattle-based Spaceflight Inc., listed three reasons why Seattle is up there with Southern California, Silicon Valley, Texas and Florida’s Space Coast when it comes to commercial spaceflight.

SpaceX goes slow on Internet satellite plan

It’s been nine months since SpaceX’s billionaire founder, Elon Musk, announced plans to put up a constellation of 4,000 satellites to provide global Internet service, and scores of employees are being hired in the Seattle area to start making it so. But today SpaceX President Gwynne Shotwell signaled that the company is reconsidering those plans.

“I would say that this is actually very speculative at this point,” Space News quoted Shotwell as saying at the Cable and Satellite Broadcasting Association of Asia convention in Hong Kong. “We don’t have a lot of effort going into that right now.”

The project is technically doable, she said. “But can we develop the technology and roll it out with a lower-cost methodology so that we can beat the prices of existing providers like Comcast and Time Warner and other people? It’s not clear that the business case will work,” she said.

NASA patents are so crazy they just might work

When NASA put out the word this month that it was offering more than 1,200 of its patented technologies to startups for no money down, the spotlight naturally fell on the farthest-out ideas – for example, a collapsible airplane suitable for sending to Mars, or solar sails for interplanetary flights.

But the real point of the exercise is to make it easier to convert NASA’s out-of-this-world ideas into profitable innovations on Earth. NASA is willing to waive the patent licensing fees for the first three years of commercialization, but will take a standard net royalty fee once businesses start selling commercial products.

The resulting products might well have nothing to do with outer space. Here are seven patented ideas that may sound crazy but could work for the right kind of startup.

Pluto’s dog-bone moon poses a puzzle

Kerberos
This image of Kerberos was created by combining four individual images from New Horizons’ Long Range Reconnaissance Imager that were captured on July 14, approximately seven hours before the spacecraft’s closest approach to Pluto, at a range of 245,600 miles (396,100 kilometers) from Kerberos. The image has bee processed to recover the highest possible resolution. (Credit: NASA / JHUAPL / SwRI)

NASA’s New Horizons probe has finally filled out its family portrait of Pluto and its moons – and Kerberos, the last moon to get its closeup, turns out to be nothing like what scientists expected.

Before the piano-sized spacecraft’s July flyby, an analysis of Kerberos’ gravitational influence on Pluto’s four other moons suggested that it had some heft. But the fact that it was so dim led the mission team to conclude it must have a dark surface. Otherwise, why would an object so large reflect so little light?

It turns out that Kerberos is almost as tiny as Pluto’s smallest moon, Styx. Like Styx, Kerberos’ surface appears to consist of relatively clean water ice, making it bright enough to reflect about half of the sunlight it receives.

Find the people in the ‘Pluto Time’ picture

During the buildup to the big Pluto flyby in July, the team behind NASA’s New Horizons mission launched a campaign to show regular folks what time of day during earthly twilight was as bright as high noon on the dwarf planet – and asked them to send in their “Pluto Time” selfies. Now those pictures have been assembled into mosaics that show off the shades of Pluto and its largest moon, Charon.

If you look closely at the blown-up view of Pluto, you’ll find a bonus: a portrait of Clyde Tombaugh, the self-taught astronomer who discovered the dwarf planet in 1930.

Is it aliens? SETI telescope targets mystery star

One of the premier telescope arrays in the search for extraterrestrial intelligence, or SETI, is focusing its antennas on an anomalously blinking star, thanks in part to speculation that the star called KIC 8462852 could harbor a network of alien megastructures.

The Allen Telescope Array, a complex of 42 radio dishes in Northern California that was funded in part by Seattle billionaire Paul Allen, has been collecting data about the star since Thursday evening, SETI Institute researcher Doug Vakoch said.

Science gives Pluto its day in the sun

The first peer-reviewed scientific paper about the New Horizons probe’s July flyby past Pluto lays out puzzling evidence that suggests the dwarf planet isn’t frozen in time. Rather, its smooth plains, high mountains and nitrogen glaciers are leading the NASA mission’s researchers to suspect that it’s geologically active even now.

“Pluto’s still got an engine, and it’s still running,” principal investigator Alan Stern of Southwest Research Institute told journalists in advance of the paper’s publication today by the journal Science.

Pluto pics reveal blue glow – and water ice

The latest pictures from NASA’s New Horizons mission to Pluto reveal for the first time that the backlit dwarf planet is surrounded by a beautiful blue glow – and also pinpoint the location of water ice deposits exposed on the surface.

Thursday’s images were released after a hubbub that suggested an “amazing” discovery would be revealed this week. Although the hype got a bit out of control, the revelations really do raise intriguing questions about Pluto’s weather and geology.

Orbiter shows how risky ‘Martian’ trek would be

Marooned astronaut Mark Watney takes a harrowing trek from Mars’ Acidalia Planitia to Schiaparelli Crater in “The Martian,” which took the top spot on last weekend’s box-office list with $55 million. But pictures of the actual terrain from NASA’s Mars Reconnaissance Orbiter suggest Watney’s trip would be even riskier in real life.

The science team behind the orbiter’s High Resolution Imaging Science Experiment, or HiRISE, captured a series of images that correspond to scenes in the movie in response to requests from Andy Weir, who wrote the book on which “The Martian” is based.
