A cargo ship from Japan pulled alongside the International Space Station on Wednesday, maneuvering close enough for the lab\u2019s robotic arm to reach out and grab it as the vehicles soared 260 miles over the South Atlantic Ocean.<\/p>\n

\u201cHTV capture complete,\u201d Japanese astronaut Kimiya Yui radioed from the ISS. \u201cI just want to say congratulations to all teams and people involved in this mission. Also, thank you very much for your hard work and support for the first HTV-X mission.\u201d<\/p>\n

The HTV-X spacecraft is an upgraded cargo freighter replacing Japan\u2019s H-II Transfer Vehicle, which successfully resupplied the space station nine times between 2009 and 2020. At the conclusion of the HTV program, Japan\u2019s space agency preferred to focus its resources on designing a new cargo ship with more capability at a lower cost. That\u2019s what HTV-X is supposed to be, and Wednesday\u2019s high-flying rendezvous marked the new ship\u2019s first delivery to the ISS.<\/p>\n

\u201cThis is a historic event in the Japanese space program,\u201d Yui said. \u201cThis spacecraft is so beautiful and shiny, and this is representing our bright future. Thank you again for delivering these important supplies and experiments. I can\u2019t wait to open this golden treasure box.\u201d<\/p>\n

A gorgeous video downlinked from orbit showed Japan\u2019s newest spacecraft approaching from underneath the ISS. The ship\u2019s bright golden thermal insulation stood out against the dark blue and green landscape of the planet far below, giving it the appearance of a supersized insect flying in formation with the station.<\/p>\n

Resupply missions to the space station have become fairly commonplace, but it\u2019s no easy feat to deliver equipment to an outpost speeding around the planet at nearly 5 miles per second. As the ISS nears the end of its life\u2014decommissioning is set to begin in 2030\u2014one of the program\u2019s enduring legacies has been fostering the development of a spectrum of crew and cargo vehicles to service it.<\/p>\n

SpaceX developed the Cargo Dragon and Crew Dragon capsules to resupply the ISS. Europe\u2019s Automated Transfer Vehicle, which flew five times to the space station, was the basis for the European-built service module for NASA\u2019s Orion spacecraft, now a core element of the Artemis lunar program.<\/p>\n

NASA is applying technology from Northrop Grumman\u2019s Cygnus cargo freighter to build parts of the Gateway space station to be constructed in orbit around the Moon. The European Space Agency hopes to use the ISS as a destination for its own new commercial supply ships in a bid to emulate what NASA did in the United States with SpaceX and Northrop Grumman.<\/p>\n

And without the ISS, Russia\u2019s human spaceflight program might be dead today.<\/p>\n

Ins and outs of HTV-X<\/h2>\n

Yui used the outpost\u2019s robotic arm to grapple the HTV-X spacecraft at 11:58 am EDT (15:58 UTC) on Wednesday. The capture capped a three-and-a-half-day transit from a launch pad on Tanegashima Island in southern Japan.<\/p>\n

The spacecraft flew to space atop Japan\u2019s H3 rocket, replacing the H-II launcher family used for Japan\u2019s previous resupply missions to the ISS. The H3 and HTV-X are both manufactured by Mitsubishi Heavy Industries.<\/p>\n

Once in orbit, HTV-X unfurled its power-generating solar panels. This is one of the new ship\u2019s most significant differences from the HTV, which had its solar panels mounted directly on the body of the spacecraft. By all accounts, the HTV-X\u2019s modified computers, navigation sensors, and propulsion system all functioned as intended, leading to the mission\u2019s on-time arrival at the ISS.<\/p>\n

Rob Navias, a NASA spokesperson, called the HTV-X\u2019s first flight \u201cflawless\u201d during the agency\u2019s streaming commentary of the rendezvous: \u201cEverything went by the book.\u201d<\/p>\n

At 26 feet (8 meters) long, the HTV-X is somewhat shorter than the vehicle it replaces. But an improved design gives the HTV-X more capacity, with the ability to accommodate more than 9,000 pounds (4.1 metric tons) inside its pressurized cargo module, about 25 percent more than the HTV. The new spacecraft boasts a similar enhancement in carrying capacity for external cargo, such as spares and science instruments, to be mounted on the outside of the space station.<\/p>\n

Japan provides resupply services to the space station to help reimburse NASA for its share of the research lab\u2019s operating costs. In addition to space station missions in low-Earth orbit, Japanese officials say the HTV-X spacecraft could haul logistics to the future Gateway mini-space station near the Moon.<\/p>\n

Officials plan to launch at least three such HTV-X missions to the ISS. There are tentative plans for a fourth and fifth HTV-X that could launch before 2030. The second HTV-X mission will attempt Japan\u2019s first automated docking with the space station, a prerequisite for any future resupply missions to the Gateway.<\/p>\n","protected":false},"excerpt":{"rendered":"
