SpaceX cargo ship reaches International Space Station

Posted: October 10, 2012 at 7:20 pm

CAPE CANAVERAL, Florida (Reuters) - Astronauts plucked a commercial cargo ship from orbit on Wednesday and attached it to the International Space Station, marking the reopening of a U.S. supply line to the orbital outpost following the space shuttles' retirement last year.

After a 2-1/2 day trip, Space Exploration Technologies' Dragon cargo ship positioned itself 33 feet away from the $100 billion research complex, a project of 15 countries, which has been dependent on Russian, European and Japanese freighters for supplies.

Astronaut Akihiko Hoshide then used the space station's 58-foot-long (17.7-meter) robotic arm to grab hold of a grapple fixture on the side of the capsule at 6:56 a.m. EDT (1056 GMT) as the spacecraft flew 250 miles above the Pacific Ocean, off the coast of Baja California in northwest Mexico.

"Looks like we tamed the Dragon," commander Sunita Williams radioed to Mission Control in Houston.

"We're happy she's on board with us. Thanks to everybody at SpaceX and NASA for bringing her here to us. And the ice cream," she said.

The Dragon's cargo includes a freezer to ferry science samples back and forth between the station and Earth. For the flight up, it was packed with chocolate-vanilla swirl ice cream, a rare treat for an orbiting crew.

Williams and Hoshide attached the capsule to a docking port on the station's Harmony connecting module at 9:03 a.m. EDT (1303 GMT).

It is expected to remain docked to the station for about 18 days while the crew unloads its 882 pounds (400 kg) of cargo and fills it with science experiments and equipment no longer needed on the outpost.

The flight is the first of 12 planned under a $1.6 billion contract NASA placed with privately owned Space Exploration Technologies, or SpaceX, to deliver cargo to the station.

The U.S. space agency's second supplier, Orbital Sciences Corp, plans to debut its Antares rocket later this year. A demonstration run to the station is planned for February or March.

Dragon is laden with scientific gear, replacement parts for the space station, and a welcome shipment of chocolate ripple ice cream stashed in an otherwise empty lab freezer the capsule carried up.

The capsule, which launched Sunday night atop SpaceX's Falcon 9 rocket, reached the orbiting outpost about 15 minutes ahead of schedule. Using the station's robotic arm, Akihiki Hoshide, a station flight engineer, snagged Dragon at 7:56 a.m. Eastern Daylight Time. A little over an hour later, Dragon was safely docked with the station.

"Looks like we've tamed the dragon," said station commander Sunita Williams when the arm initially captured the capsule.

"We're happy she's on board with us," she said, adding a special shout-out for the ice cream.

The mission marks an important milestone for NASA along a path first set out under the Bush administration and confirmed by President Obama. After the space shuttle Columbia disaster in February 2003, NASA has pivoted to focus on sending humans beyond low-Earth orbit, while it has steered the job of ferrying supplies and astronauts to the space station to private companies.

The effort to carry astronauts to and from low-Earth orbit took a step forward in August, when NASA announced agreements worth a combined $1.1 billion to help SpaceX, Boeing, and Sierra Nevada Corporation develop such capabilities. But Dragon's arrival at the space station Wednesday the first flight under a 12-flight, $1.6-billion contract shows that the goal of bringing commercial carriers into the station resupply business is now being realized.

SpaceX Dragon Capsule to Dock with Space Station Today

Posted: at 7:20 pm

SpaceX's robotic Dragon cargo ship is slated to arrive at the International Space Station early this morning (Oct. 10) for a nearly three-week stay.

The Dragon spacecraft has been chasing down the huge orbiting lab since launching Sunday night (Oct. 7) atop SpaceX's Falcon 9 rocket. If all goes according to plan, the unmanned capsule will approach the station in a series of cautious steps early today, then finally be snagged by its huge robotic arm at 7:17 a.m. EDT (1117 GMT).

NASA will broadcast the action live on NASA TV and online. You can watch the Dragon docking webcast live here beginning at 4 a.m. EDT (0800 GMT).

Dragon will have to pass a series of "go/no go" tests this morning, beginning at 5:13 a.m. EDT (0913 GMT), as it sidles up to the station. The aim is to assure SpaceX and NASA engineers that it's operating nominally during approach and poses no threat to the $100 billion orbiting lab or its three current residents. [Video: Dragon Launches Toward Space Station]

If it passes all of these trials, NASA astronaut Sunita Williams and Japanese spaceflyer Akihiko Hoshide will grapple the capsule using the station's 58-foot (18 meters) robotic arm. They'll guide Dragon to the Earth-facing side of the orbiting lab's Harmony module, where it will be bolted in place for an 18-day stay.

Dragon is embarked on the first-ever bona fide cargo mission to the space station by a private vehicle. It's carrying 1,000 pounds (454 kilograms) of supplies and scientific experiments, and it will return to Earth on Oct. 28 with a different load of gear totaling about 2,000 pounds (907 kg).

Dragon's mission is the first of 12 unmanned supply runs California-based SpaceX will make to the station under a $1.6 billion contract with NASA. The space agency also inked a $1.9 billion deal with Virginia-based Orbital Sciences Corp. to fly eight cargo missions with its Antares rocket and Cygnus spacecraft.

The Dragon capsule has visited the station once before. This past May, it became the first private vehicle ever to dock with the 430-ton orbiting complex on a historic demonstration mission intended to show that SpaceX was ready to begin making its contracted flights.

Orbital Sciences, for its part, plans to test-fly the Antares rocket for the first time later this year.

With its venerable space shuttle fleet now retired, NASA is looking to private American vehicles to fly both cargo and crew to low-Earth orbit. The space agency hopes at least two different commercial spaceships are ready to carry crew by 2017; until then, the nation will be dependent on Russian Soyuz spacecraft to ferry its astronauts to the space station and back.

Singer Sarah Brightman Will Ride Russian Rocket to Space

Posted: at 7:20 pm

British soprano singer Sarah Brightman has announced her plan to ride a Russian rocket into space for a 10-day visit to the International Space Station.

Brightman made her announcement today (Oct. 10) from Moscow during a press conference with Roscosmos (the Russian Federal Space Agency) and Space Adventures, the Virginia firm that brokered the deal.

"Throughout most of my life I've felt an incredible desire to take the journey to space that I have now begun," Brightman said. "A journey into space is the greatest adventure I can imagine."

The singer will be the eighth private citizen to pay her way to space. The last space tourist, Canadian Cirque du Soleil founder Guy Laliberte, flew to orbit in 2009 for about $35 million. Space Adventures is not releasing the cost of Brightman's ticket, but it is almost certainly more than Laliberte's. [Photos: The First Space Tourists]

"The price of the flight is confidential, but it is a roundtrip ticket," said Eric Anderson, chairman of Space Adventures.

Brightman, who rose to fame starring in the original Broadway production of "Phantom of the Opera," said space has influenced her from a young age.

"My music has always been inspired by space," Brightman said. "It was because of seeing the first man on the moon back in the '60s that actually inspired me and gave me the courage to go into the career that I had. At moments when I'm feeling nervous onstage or I'm feeling unsure I actually look to the stars and the planets and space and it gives me courage and inspiration."

Brightman will begin a six-month cosmonaut training regime in Star City, Russia, after she completes a year-long world tour for her new album, "Dream Chaser," starting in January.

"This past July, Ms. Brightman completed and passed all of the required medical and physical evaluations; she's fit and mentally prepared for our spaceflight training program," Alexey Krasnov, head of Roscosmos' Piloted Programs Department, said in a statement. "We will work closely with Space Adventures in supporting Ms. Brightman's spaceflight candidacy."

She will be part of a three-person crew launching on a Soyuz spacecraft from the Baikonur Cosmodrome in Kazakhstan sometime after that. She will spend 10 days aboard the space station, which orbits Earth from 240 miles (386 km) overhead.

SpaceX Dragon capsule arrives at space station

Posted: at 7:20 pm

CAPE CANAVERAL, Fla. (AP) -- A private company successfully delivered a half-ton of supplies to the International Space Station early Wednesday, the first official shipment under a billion-dollar contract with NASA.

The SpaceX cargo ship, called Dragon, eased up to the orbiting lab, and station astronauts reached out with a robot arm and snared it. Then they firmly latched it down.

"Looks like we've tamed the Dragon," reported space station commander Sunita Williams. "We're happy she's on board with us."

Williams thanked SpaceX and NASA for the delivery, especially the chocolate-vanilla swirl ice cream stashed in a freezer.

The linkup occurred 250 miles above the Pacific, just west of Baja California, 2 days after the Dragon's launch from Cape Canaveral, Fla.

"Nice flying," radioed NASA's Mission Control.

It's the first delivery by the California-based SpaceX company under a $1.6 billion contract with NASA. The contract calls for 12 such shipments.

This newest Dragon holds 1,000 pounds of groceries, clothes, science experiments and other gear. Williams and her crew won't get access to all that until Thursday, when the hatch is opened.

The vessel will remain at the space station for nearly three weeks before departing with almost twice that much cargo at the end of the month. Dragon is the only cargo ship capable of bringing back research and other items, filling a void left by NASA's retired shuttles.

SpaceX owned by PayPal's billionaire creator Elon Musk launched Dragon aboard a Falcon 9 rocket Sunday night. One of the nine first-stage engines failed a minute into the flight, but the other engines compensated and managed to put the capsule into the proper orbit. The mishap, however, left a secondary payload aboard the rocket an Orbcomm communication satellite in too low of an orbit.

A privately built robotic space capsule arrived at the International Space Station early Wednesday (Oct. 10) to make the first-ever commercial cargo delivery to the orbiting lab under a billion-dollar deal with NASA.

The unmanned Dragon spacecraft was captured by station astronauts using a robotic arm after an apparently flawless approach by the cargo-laden space capsule, which was built by the private spaceflight company SpaceX. It is the first of 12 resupply flights SpaceX will fly for NASA under a $1.6 billion deal.

"Looks like we've tamed the Dragon," station commander Sunita Williams said as the spacecraft was captured by a robotic arm. "We're happy she's onboard with us. Thanks to everyone at SpaceX and NASA for bringing her to us and the ice cream."

The SpaceX spacecraft was captured at about 6:56 a.m. EDT (1122 GMT) by Japanese astronaut Akihiko Hoshide as the space station soared 250 miles (402 kilometers) above the Pacific Ocean, just west of Baja California. The capsule will be attached to an open docking port on the station in the next few hours.

Dragon cargo ship captured, berthed to space station

Posted: at 7:20 pm

After a flawless final rendezvous, a commercial SpaceX cargo ship is captured by the International Space Station's robot arm and attached to a docking port for unloading.

The SpaceX Dragon cargo ship was captured by the International Space Station's robot arm early Wednesday after a smooth rendezvous. The astronauts operating the arm then attached the cargo craft to the forward Harmony module's Earth-facing docking port.

After getting off to a rocky start with an engine failure during launch Sunday, a commercial cargo capsule loaded with a half-ton of equipment and supplies -- including ice cream -- carried out a flawless final approach to the International Space Station early Wednesday, pulling up to within 60 feet so Japanese astronaut Akihiko Hoshide, operating the lab's robot arm, could pluck it out of open space for berthing.

Making the first of at least 12 cargo deliveries under a $1.6 billion contract with NASA, the SpaceX Dragon capsule, after a successful test flight last May, is the first commercially developed spacecraft to visit the station, the centerpiece of a push to restore U.S. resupply capability in the wake of the space shuttle's retirement last year.

Hoshide used the station's robot arm to latch onto a grapple fixture on the side of the Dragon capsule at 9:56 a.m. PT as the two spacecraft sailed 250 miles above the Pacific Ocean west of Baja California.

"Houston, station on (channel) two, capture complete," Expedition 33 commander Sunita Williams radioed. "Looks like we've tamed the dragon. We're happy she's on board with us. Thanks to everybody at SpaceX and NASA for bringing her here to us. And the ice cream."

Williams and Hoshide then maneuvered the Dragon capsule to the Earth-facing port of the forward Harmony module and locked it in place at 12:03 p.m., completing the rendezvous and berthing.

"The control center team here and the team out at Hawthorne (Calif.) at SpaceX just did a phenomenal job of making a pretty complex ballet in space look pretty easy," said Bill Gerstenmaier, NASA's director of space operations. "And it was not easy by any stretch of the imagination. But they just did a great job, and it's great to have the Dragon spacecraft on board the space station."

Space station commander Sunita Williams photographs the approaching Dragon cargo ship during its final approach to the lab complex Wednesday.

The long-awaited commercial cargo mission began with a spectacular launch Sunday night from the Cape Canaveral Air Force Station in Florida. But during the climb to space, one of the Falcon 9 booster's nine first-stage engines malfunctioned and shut down, forcing the flight computer to fire the other engines longer than planned to compensate for the shortfall.

Space station pulls in SpaceX cargo ship

Posted: at 7:20 pm

When NASA's space shuttle fleet retires in 2011, the space agency will have to rely on Russian spacecraft and the private sector to taxi cargo and humans to and from the International Space Station, even as it turns its focus to the technologies required to send humans beyond low-Earth orbit.

President Barack Obama views the policy as a boost to the nascent commercial spaceflight industry, where competition is already heating up to supply the taxi services. Some companies are also talking about offering out-of-this-world rides for researchers as well as tourists with deep pockets and a serious case of star lust. Click ahead to check out 10 of the top players in the race to commercialize space.

Space Exploration Technologies

PayPal co-founder Elon Musk has already signed up NASA as a marquee account for his high-flying venture, Space Exploration Technologies, also known as SpaceX. The government has a $1.6 billion contract with the Hawthorne, Calif., company to provide unmanned cargo deliveries to the International Space Station starting in 2011 with its Falcon 9 rocket and Dragon capsule.

This image shows the successful test launch of the Falcon 9 rocket on June 4. The rocket will eventually carry the Dragon to orbit. If all goes according to plan, astronauts may get a lift as well, starting in 2013. SpaceX has also secured contracts to launch next-generation satellites for the telecommunications company Iridium.

Orbital Sciences

Another NASA contract this one worth a reported $1.9 billion is in the bag at Virginia-based Orbital Sciences, which is planning to supply the International Space Station with its unmanned Cygnus spacecraft, shown here in an artists rendering. A newly-developed Taurus 2 rocket will ferry the cargo ship to space. If the opportunity presents itself, the company may advance plans to ferry humans to orbit as well.

Boeing

Boeing, the aerospace giant, has unveiled plans to flesh out designs and build a new capsule-based spaceship called the CST-100, which will take cargo and passengers to the International Space Station. The development push comes thanks to an $18 million NASA grant.

The Apollo-like capsule will carry a crew of seven and be designed to launch on a variety of rockets, including the Atlas and Delta rockets operated by the Boeing-Lockheed Martin joint venture known as the United Launch Alliance, as well as SpaceX's Falcon. Extra seats may be made available for paying passengers through a marketing arrangement with Space Adventures.

Space Station Arm "Tames" Dragon Capsule—SpaceX Docking Is a First

Posted: at 7:20 pm

For the second time in five months, the commercial rocket company SpaceX has successfully docked its Dragon capsule at the International Space Station (ISS)this time on its first official cargo run under a supply contract with NASA.

"Looks like we've tamed the Dragon," station commander Sunita Williams, a U.S. Navy officer, told controllers on the ground after the ISS's robotic arm had grabbed the unmanned craft just before 7 a.m. ET, accomplished with the assistance of Japanese astronaut Akihiko Hoshideh. (Related: "Robot Arm to Grab Robotic ShipA Space Station First.")

"We're happy she's on board with us."

SpaceX's Dragonthe first and only commercial spacecraft to berth at the stationmade contact with the station 252 miles (406 kilometers) above Earth. The capsule is packed with nearly a thousand pounds (450 kilograms) of essential supplies and gear, as well some arguably nonessential chocolate-vanilla swirl ice cream and, for a school science experiment, some Silly Putty.

High-flying SpaceX, founded by PayPal co-founder Elon Musk, won a nearly U.S. $1.6 billion contract with NASA in 2008 to supply the space station via a dozen flights in the years ahead.

Unlike any government-owned capsules supplying the ISS, the SpaceX Dragon is designed to return intact to Earth, and so can be used as a two-way ferry. The capsule brought back 1,300 pounds (590 kilograms) of science experiments and space hardware after its test berthing in May and will do the same later this month.

SpaceX Contract an Investment in the Future?

Today's first formal berthing at the International Space Station under the NASA cargo-supply contract was broadly cheered as a milestone, and perhaps a harbinger of much more to come.

"I think it would be fair to say the successful docking under the NASA contract is parallel to the early days of the commercial airline industry," said John Logsdon, space policy emeritus professor at George Washington University and longtime NASA adviser.

"The government paid airline owners to deliver the mail and gave the early industry the financial support it needed to grow," he said. "Clearly, NASA is hoping the same will happen herethat giving commercial space companies contracts to supply the space station will act as a huge boost to the early commercial space industry."

Berkeley Lab Researchers Develop New Tool for Making Genetic Engineering of Microbial Circuits Reliably Predictable

Synthetic biology is the latest and most advanced phase of genetic engineering, holding great promise for helping to solve some of the world's most intractable problems, including the sustainable production of energy fuels and critical medical drugs, and the safe removal of toxic and radioactive waste from the environment. However, for synthetic biology to reach its promise, the design and construction of biological systems must be as predictable as the assembly of computer hardware.

An important step towards attaining a higher degree of predictability in synthetic biology has been taken by a group of researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) under the leadership of computational biologist Adam Arkin. Arkin and his team have developed an "adaptor" that makes the genetic engineering of microbial components substantially easier and more predictable by converting regulators of translation into regulators of transcription in Escherichia coli. Transcription and translation make up the two-step process by which the coded instructions of genes are used to synthesize proteins.

"Application of our adaptor should produce large collections of transcriptional regulators whose inherent composability can facilitate the predictable engineering of complex biological circuits in microorganisms," Arkin says. "This in turn should allow for safer and more efficient constructions of increasingly complex functions in microorganisms."

Arkin is the director of Berkeley Lab's Physical Biosciences Division and the corresponding author of a paper describing this work in Nature Methods. The paper is titled "An adaptor from translational to transcriptional control enables predictable assembly of complex regulation. Co-authoring this paper were Chang Liu, Lei Qi, Julius Lucks, Thomas Segall-Shapiro, Denise Wang and Vivek Mutalik.

Synthetic biology combines modern principles of science and engineering to develop novel biological functions and systems that can tackle problems natural systems cannot. The focus is on bacteria and other microbes that can metabolize a wide variety of valuable chemicals and molecules, and play a critical role in the global cycles of carbon and other important elements. One of the keys to success in synthetic biology is the design and construction of customized genetic switches in microbes that can control the expression of both coding and non-coding RNA, act on operons (small groups of genes with related functions that are co-transcribed in a single strand of messenger RNA), and be tethered to higher-order regulatory functions (a property called composability).

"Much of the regulatory potential of a bacterium is contained in the five-prime untranslated regions (UTRs), which control the expression of physically adjacent downstream genes and have become attractive platforms for a parts-based approach to synthetic biology," Arkin says. "This approach, in which integrated engineered regulatory parts respond to custom inputs by changing the expression of desired genes, must satisfy two criteria if it is to have long-term success. First, the regulatory parts must be easily engineered in a way that yields large homogenous sets of variants that respond to different custom inputs, and second, the parts must be composable such that they can be easily and predictably assembled into useful higher-order functions."

In the five prime UTRs of bacteria, two primary types of regulators can serve as starting points for designing new parts - those that regulate transcriptional elongation, in which cellular inputs are linked to the process by which a sequence of DNA nucleotides is transcribed into a complementary sequence of RNA; and those that regulate translation, in which a ribosome translates the RNA message into a protein. Transcriptional elongation regulators meet the second criterion by featuring versatility and composability that makes them ideal for building custom regulatory functions. Translational regulators meet the first criterion by being easier to engineer and relatively common to all bacteria.

"Our solution for meeting both criteria was to develop an adaptor based on tryptophanase, the catabolic operon for tryptophan that converts regulators of translational initiation into regulators of transcriptional elongation," Arkin says. "Because our adaptor strategy bypasses the otherwise restrictive tradeoff between criterion one and criterion two, we believe it will have a crucial role in the long-term development of five prime UTRs as platforms for the design and integration of custom regulatory parts."

When an E.coli translational regulator was fused to the adaptor created by Arkin and his colleagues, it was also able to control transcriptional elongation. The team applied their adaptor to the construction of several transcriptional elongation regulators that respond to RNA and small-molecule inputs. Included were five mutually orthogonal RNA-triggered attenuators (meaning they can terminate transcription), which the team assembled into logic gates driven by two, three or four RNA inputs that linked to ribosome binding sites. Because their adaptor is so easily linked to ribosome binding sites, a common mechanism in bacteria, the team believes the adaptor will be widely applicable.
