Japan launches new cargo craft to space station

The Japanese space agency launched a powerful new rocket Thursday carrying an unmanned space station cargo ship on a complex maiden voyage to deliver some 7,400 pounds of equipment and supplies to the orbital outpost.

With four strap-on boosters gushing white-hot exhaust and a pair of hydrogen-fueled main engines roaring at full throttle, the H-2B rocket thundered away from launch pad 2 at the Tanegashima Space Center in southern Japan at 1:01:46 p.m. EDT.

"The launch was beautiful," Stephen Clark, a U.S. journalist representing Spaceflight Now, said in an instant message from Tanegashima. "The boosters lit with the typical orange glow and away she went. The rocket went into a thick cloud layer around 25 seconds after liftoff, but the rumble shook us for a couple minutes more."

The H-2B's first and second stages worked as planned and 15 minutes after liftoff, the HTV cargo craft was released into its planned preliminary orbit, prompting an enthusiastic round of applause in the Japanese control center.

The $680 million mission represents a critical milestone for the post-shuttle space station program as NASA and its international partners work to keep the lab complex resupplied after the space shuttle is retired late next year.

The HTV cargo craft, developed by the Japan Aerospace Exploration Agency, or JAXA, as a contribution to the station program, measures some 32 feet long, 14.4 feet wide and weighs some 23,000 pounds when carrying a full 13,200-pound load of cargo. For its maiden flight, the HTV-1 is carrying about 3.5 metric tons of equipment and supplies.

Unlike Russian Progress supply ships of the European Space Agency's automated transfer vehicle, or ATV, the Japanese HTV features a pressurized section accessible by the station crew and an unpressurized cargo bay to carry experiments and hardware that can be mounted on the station's hull.

And unlike the Progress and the ATV, the Japanese ship is not designed to dock with the station on its own. Instead, the spacecraft autonomously maneuvers to a position just below the station and waits for the lab's robot arm to grapple it and move it to a docking port.

"On this particular flight, we've got about 2 1/2 tons of pressurized cargo flying to orbit and almost a metric ton of payloads externally coming to ISS," space station Program Manager Mike Suffredini said at a pre-launch briefing. "So it's a significant amount of up mass to us and it's not only important logistics for the crew, which is a major part of the pressurized capability, but also quite a bit of payloads."

One of the payloads in the HTV's unpressurized cargo bay is a NASA experiment to map the constituents of the upper atmosphere and the other is a JAXA payload designed to study the effects of trace gases on the ozone layer. Both will be extracted from the HTV cargo bay by the station's robot arm and installed on an external porch by a Japanese robot arm on the Kibo lab module.

"Those are very critical things for us to understand relative to understanding our environment and how we affect it and it's good to be able to finally start having this kind of research on board ISS," Suffredini said.

Not only is the flight a maiden voyage for the HTV, it also was the maiden flight of Japan's new H-2B rocket, a much more powerful version of JAXA's hydrogen-fueled H-2A booster. The new rocket features four strap-on solid-fuel boosters instead of two, and two hydrogen-fueled first-stage engines instead of one. The upper stage features a single hydrogen-powered engine.

JAXA currently plans to build and launch one HTV craft per year, although the agency could support two flights annually if necessary.

The HTV-1 flight plan calls for a full week of orbital tests and checkout before final approach to the space station, including tests to exercise the craft's abort modes. Capture is planned for flight day eight.

Final approach will begin at a point about 3.1 miles directly behind the International Space Station. The HTV-1 will maneuver itself to a position about 1,000 feet below the lab complex and then carry out a 180-degree yaw maneuver to permit an abort, if necessary, when the craft is closer to the station.

From there, it will continue the approach to a point about 100 feet below the station and pause once again before proceeding to the capture point just 29 feet from the laboratory complex.

At that point, with the HTV-1 in free drift, station flight engineer Nicole Stott will use the lab's robot arm to lock onto a grapple fixture. Canadian astronaut Robert Thirsk then will take over and guide the HTV-1 to a docking at the Harmony module's nadir, or Earth-facing, port.

The day after capture, the crew will open hatches between Harmony and the HTV and begin moving equipment and supplies into the station.

what I think is a bit stupid (and please correct me if things have changed) is the fact that the united states is spending all this money on contributing to this space station and when they finally finish it our space shuttles will be to old to operate and we will be forced to rent out other countries shuttles to get there, and from what I heard the best choice is using russias shuttle. I know this article has nothing to do with the u.s. but i had to throw it in

Russia's shuttle program was cancelled some time ago. The US is currently moving to a new rocket program, and leaving the shuttle grounded after the final six missions.

Today, in fact, was the first full-sized, full-scale, test firing of the new rocket. It was laying on it's side on a test bed in Utah, at the rocket maker's test site. See http://www.nasa.gov for more info.

Stupid? No. Poor timing, perhaps. The shuttle, while a wonderful program, never fully met cost goals, in part because the US military required changes to the design to accommodate their needs - but that was not the only reason. Two shuttle disasters also raised the costs of the program. In the end, it was a limited capability vehicle that served several purposes, but that met the same fate as all previous vehicles: it simply grew outdated for our visions of the future.

Re: "and from what I heard the best choice is using Russia's shuttle."

Interestingly, the Russian Federation will be relying on the IBM OS/2 Operating System that control its rocket launches.

So, just what is wrong with this picture!!!

I was going off a Longview daily news article from a couple of years ago thanks for the correction I was way off

The thing is, to build the new system, they have to shut down the Shuttle Program all together to reallocate monetary resources.

Well any way, way to go Japan.

Great job Japan it's about time. Looking into your recent past, you have been dreaming of the stars and now they are within your grasp. WORK HARD and ACHIEVE YOUR DREAM!

Filipiaks coment: "In the end, it was a limited capability vehicle that served several purposes, but that met the same fate as all previous vehicles: it simply grew outdated for our visions of the future"

I always felt that the shuttle program was a step forward in to the future and now we are going back to capsules, what kind of vision is that? It seems we have become cowards in our own dream of reaching for the stars. Sad to say our vision has grown dim. By now we should have had a manned reusable spaceship traveling all over the solar system. This BOLD step could have saved billions in the space program. Don't say we do not have the technology, because we do. If another nation has the gonads to take the bold step that we refuse to take then bully for them!

The Russians appear to be selecting a capsule design (instead of Clipper) for their Soyuz replacement !

For lifting body/shuttle fans -- Never Fear -- DARPA / Boeing X-37B Orbital Test Vehicle will launch on an Atlas V sometime in January 2010 from Cape Canaveral Air Force Station in Cape Canaveral, Fla (only a few months away!)
This Space Plane prototype -- was based on earlier NASA X-40 and X-37(a) work.

From the refurbished Launch Pad 40 (old 1960s USAF MOL/Titan III pad) ...
SpaceX is ready for its inaugural test launch of the Falcon 9 from Cape Canaveral Air Force Station, Fla.

That does not include work by ESA and Russians on new Soyuz launch pad and capabilities at French Guiana -- scheduled for February/March 2010 !

Until Bin Laden does not open up a Training Camp on the Moon, NASA will spend Tax payers money just for the Executives on Earth!
I forgot, NASA go back and landing there "Capsules" in the Ocean and Desert, again!
America has a dream.

Maybe, in a few years I can book a Flight with a Private Company, and will be able to knock on the Door of the ISS for a Coffee ;-)
