Littleton-based Lockheed Martin Space Systems is jumping into the entry pool to be selected to ferry supplies to and from the International Space Station.

The company submitted a three-part system the Jupiter reusable spacecraft, Exoliner cargo container and a long robotic arm inspired by the space shuttle's similar appendage to try to win a piece of the $14 billion NASA pie.

"We know how important it is to get astronauts on the ISS the supplies they need on time, every time," said Wanda Sigur, vice president of Lockheed Martin's civil space division. "Our approach is designed to deliver a large volume of critical supplies and cargo with each flight, and do so on schedule."

Here's how it works: Jupiter and Exoliner would launch on a United Launch Alliance Atlas V rocket and deliver their cargo to ISS. Jupiter would remain in orbit, leaving the old Exoliner behind on ISS.

Once another Exoliner cargo delivery arrives, Jupiter would remove the old Exoliner from ISS, and replace it with the new. The old cargo container would fall from orbit, burning up upon re-entry to Earth's atmosphere.

As part of the bid for the National Aeronautics and Space Administration's Commercial Resupply Services 2 contract, the company is positioning the configuration as a potential support for future deep-space exploration think interstellar mini-marts placed throughout space, serving as pre-positioned stations to provide astronauts with food, fuel and equipment.

Lockheed Martin looked to its previous designs to guide its commercial resupply contract entry. Jupiter builds on the heritage of MAVEN, currently in orbit around Mars, and asteroid explorer OSIRIS-REx, currently under construction at the company's Waterton Canyon facility.

The company also looked to the cargo carrier used on the space station's current Automated Transfer Vehicle to guide the Exoliner, which would have both pressurized and unpressurized cargo capacity.

The award of the contract to Lockheed Martin would bring work to Colorado, including engineering, production and testing of the Jupiter spacecraft and Exoliner's unpressurized cargo carrier and Mission Support Module, which carries Jupiter's refueling supply, according to company spokeswoman Allison Rakes.

Wednesday is the 50th anniversary of the worlds first spacewalk, by cosmonaut Alexei Leonov. Since then, astronauts have accomplished many milestones beyond the confines of a spacecraft

Today marks 50 years since Alexei Leonov of the former Soviet Union floated beyond the bounds of his Voskhod 2 space capsule in the worlds first spacewalk. During his 10-minute extravehicular activity (EVA), Leonov changed the way humans exist in the universe. No longer were we bound to the ground of our home planet, or even the manmade grounds of our space vehicleswe could be in the universe on our own, with only the thin protection of a spacesuit between our skin and the raw expanse of the cosmos. The ability to fly outside a spacecraft was also critical for many of humankinds greatest achievements in space, such as walking on the moon, repairing the Hubble Space Telescope and other satellites in orbit, and assembling the International Space Station.

These days NASA, the Russian Federal Space Agency and even the China National Space Administration, are old pros at managing spacewalkssometimes complicated maneuvers that last hours and feature multiple astronauts. But back on March 18, 1965, Leonov was flying, literally, into unknown territory. As he told The Smithsonians Air and Space Magazine in 2005, even his family did not know he would be making the spacewalk until it happened, prompting his four-year-old daughter, watching him on TV, to wail, Please tell Daddy to get back inside. w. And the lack of atmospheric pressure out in space caused Leonovs suit to deform in unexpected ways, making it difficult for him to reenter his spacecraft and putting his life at risk. He managed, however, and racked up an important success in the space race, beating the Americans by less than three months (Ed White made the first U.S. spacewalk on June 3, 1965, from Gemini 4).

We have come a long way since then, and still have a long way to go, in our quest to live and work seamlessly in space. Below are the greatest hits of spacewalking historyyou can see a slideshow of these feats here: 50 Years of Walking Through Space [Slideshow]

The Greatest Spacewalking Feats of All Time

The First Spacewalk March 18, 1965 Soviet cosmonaut Alexi Leonov became the first person to float outside a spacecraft during a 10-minute excursion on the Voskhod 2 mission. His spacesuit deformed in the vacuum of space, forcing Leonov to vent oxygen out of his suit to squeeze himself back inside.

The First American Spacewalk June 3, 1965 NASA astronaut Edward H. White, II, doubled Leonovs time when he made the U.S.s first spacewalk less than three months later. White floated outside his Gemini 4 capsule for 21 minutes, using a zip gun that ejected pressurized oxygen to maneuver himself around in space. White enjoyed using the gun, but subsequent spacewalkers reported that it was difficult to operate, so it was rarely used after the Gemini program.

The First Untethered Spacewalk February 7, 1984 Until the space shuttle Challengers STS-41B mission, spacewalkers were tethered to their spaceships by a long cord. These tethers also limited their movements, however, and sometimes made maneuvering difficult. Astronaut Bruce McCandless II was the first to test out the Manned Maneuvering Unita type of jetpack that he wore on his back to steer himself around. Unchecked by a tether, McCandless flew 100 meters out from the shuttles cargo baythe farthest a spacewalker had ever been before.

Hubble Repair Spacewalks December 5-9, 1993 The Hubble Space Telescope was launched to much fanfare in April 1990, but soon after it became apparent that the observatorys optics were flawed. To save the $2.5 billion telescope, NASA sent seven astronauts on a rescue mission onboard the shuttle Endeavour. Four of the STS-61 crew F. Story Musgrave, Jeffrey A. Hoffman, Kathryn C. Thornton and Thomas D. Akerscompleted five spacewalks in five days to install a new primary camera and corrective optics package for the telescope. Their efforts paid offthe telescope delivered on its promise to reveal the cosmos in brand new waysand four more servicing missions followed in the coming years to upgrade the observatory, which could operate through 2020.

50 Years of Walking in Space: Spacewalkings Greatest Hits

Air was pumped out of the International Space Station's air lock for the first time in the name of science last week. Inside the cylindrical Quest airlock, ESA astronaut Samantha Cristoforetti and NASA's Terry Virts monitored their breathing for researchers back on Earth.

With each lungful of air, our bodies absorb oxygen and exhale waste-product molecules such as carbon dioxide and the important 'signalling' molecule nitric oxide. The Airway Monitoring experiment looks at the amount of nitric oxide the astronauts expelled by the astronauts in the airlock.

Nitric oxide is a gas found in cigarette smoke and car exhaust, for example, and it is produced in our bodies to regulate blood vessels and act as an antibacterial agent.

Doctors measure the amount of nitric oxide exhaled by patients to help diagnose inflamed lungs and asthma.

Airway monitoring for space and Earth On Earth, dust drifts to the floor where vacuum cleaners or a damp cloth remove it easily. In weightlessness, dust circulates freely and often irritates and inflames eyes and lungs.

In addition, dust on the Moon and probably Mars sticks to astronauts through static electricity and has sharp edges - all making it more likely that dust will enter astronauts' lungs and do harm.

The Airway Monitoring experiment will test the use of nitric oxide as a tool to monitor lung inflammation as well as charting lung health in astronauts.

Four sessions will see the pair exhale into the equipment. Samantha and Terry made their first contributions before flight at NASA and ran their first space session in space in January.

On Friday, they entered the Station's Quest airlock for their last run and reduced the pressure by 30% - equivalent to being on a mountain at 3000 m altitude.

They are the first of eight astronauts to collect data on their lungs for this experiment. It is also the first time that Quest is used for scientific purposes - the module was installed to allow astronauts to venture outside on spacewalks.

The first one-year crew for the International Space Station is set to launch Friday, March 27. NASA Television will provide extensive coverage of the launch and the crews arrival to the orbital laboratory.

NASA astronaut Scott Kelly and Russian Federal Space Agency (Roscosmos) cosmonaut Mikhail Kornienko will spend a year living and working aboard the space station and will launch with cosmonaut Gennady Padalka. The trio will become part of the stations Expedition 43 crew.

NASA TV coverage will begin at 2:30 p.m. EDT March 27, with launch scheduled for 3:42 p.m. (1:42 a.m. Saturday, March 28 in Baikonur) from the Baikonur Cosmodrome in Kazakhstan. The trio will ride to space in a Soyuz spacecraft, which will rendezvous with the space station and dock after four orbits of Earth. Docking to the space station's Poisk module will take place at 9:36 p.m. Friday. NASA TV coverage of docking will begin at 8:45 p.m.

Hatches between the Soyuz and the station will be opened at approximately 11:15 p.m., at which time Expedition 43 Commander Terry Virts of NASA and his crewmates, Anton Shkaplerov of Roscosmos and Samantha Cristoforetti of ESA (European Space Agency), will greet Kelly, Kornienko and Padalka. Hatch opening coverage begins on NASA TV at 10:45 p.m.

Kelly and Kornienko will spend a year on the space station to better understand how the human body reacts and adapts to the harsh environment of space. Data from the expedition will be used to determine whether there are ways to further reduce the risks on future long-duration missions to an asteroid and eventually Mars.

The crew will support several hundred experiments in biology, biotechnology, physical science and Earth science -- research that impacts life on Earth. Data and samples will be collected throughout the year from a series of studies involving Scott and his twin brother, former NASA astronaut Mark Kelly. The studies will compare data from the genetically-identical Kelly brothers to identify any subtle changes caused by spaceflight.

Padalka will spend six months aboard the outpost, during which he will become the first four-time station commander and record holder for most cumulative time spent in space.
