December 12

At 1237 GMT today the Interstellar Vehicle Marco Polo successfully activated its Space Manifold Transition System at a distance of 2 million kilometers from the Earth. The spacecraft entered gimelspace on a vector aimed at the Gliese 745b star system. Estimated travel time is 90 days.

Mission Commander Jorge Hernandez transmitted a statement before activating the SMTS: "This is the Interstellar Vehicle Marco Polo, ready to enter gimelspace. The human adventure in space continues."

Direct communication with the spacecraft is impossible while in gimelspace, and its destination star system lies 29 light-years from Earth. Any further messages must be carried by unmanned rockets.

December 11

The Interstellar Vehicle Marco Polo deployed its Space Manifold Transition System today, in preparation for transition to gimelspace on December 12. The vehicle also began powering up its capacitors for the transition event.

0710 GMT: Interstellar Drive Specialist Martha Okome and Payload Specialist Patrick Ryan enter the airlock and begin depressurizing.

0739: Airlock depressurization is complete. Ryan and Okome exit the spacecraft and put on their Personal Maneuvering Device (PMD) packs.

0803: Okome and Ryan maneuver to the cargo module along the Main Truss of Marco Polo where the primary SMTS unit is stowed.

0818: Cargo unit hatch open.

0823: Tiedowns securing the SMTS are disconnected. Ryan and Okome begin moving the unit out of the cargo module.

0844: The SMTS is free of the cargo module and floating free next to Marco Polo.

0915: Interstellar Drive Specialist Okome begins deploying the SMTS unit to full size.

0956: SMTS unit reaches its full 20-meter diameter. Using their PMD packs, Okome and Ryan begin moving it toward the front end of the spacecraft.

1034: Ryan and Okome secure the SMTS unit to the tethers at the nose of the spacecraft.

1050: Payload Specialist Ryan attaches the Flexible Power Conduit to the SMTS unit.

1105: Okome and Ryan stand by at the airlock while system tests proceed.

1120: Okome and Ryan re-attach the Flexible Power Conduit after conductance tests show a gap.

1158: Ryan and Okome remove their PMD packs and enter the airlock.

Consult the UNICA Spacecraft Tracker site to follow Marco Polo as it makes the transition to gimelspace. The event should be visible to observers on Earth at about 1200 GMT on December 12. If the weather is clear, it should be visible from dark-sky locations east of Karachi, Pakistan and north of Darwin, Australia.

December 10

The Interstellar Vehicle Marco Polo performed its final acceleration today before making its scheduled gimelspace transition on the way to Ilmatar. The 10-minute main engine burn began at 1214 GMT and increased the spacecraft's velocity to 35 kilometers per second. Most of that velocity comes from the orbital motion of the Earth around the Sun and the spacecraft's encounter with the Moon.

December 7

The Interstellar Vehicle Marco Polo successfully passed within 20 kilometers of the Moon's surface during a gravity-assist maneuver. The encounter with the Moon gave Marco Polo a velocity boost of just over 2 kilometers per second, including the acceleration from the spacecraft's own main engine.

0200 GMT: The crew of Marco Polo secure themselves for acceleration. All loose items are stowed away and all the vehicle's nonessential systems are put in standby mode.

0239: Marco Polo passes over Petavius Crater on the Moon at an altitude of 72 kilometers.

0244: Marco Polo begins a four-minute main engine burn while passing over Scaliger Crater at an altitude of 19 kilometers above the Lunar surface.

0245: Main engine powers up to 110% thrust.

0248: Main engine shutdown as the Marco Polo passes over Gagarin Crater at an altitude of 34 kilometers. At this point its velocity is 2.4 kilometers per second relative to the Lunar surface below.

0252: Marco Polo passes over the center of the Moon's far side, now on a free trajectory aimed at the constellation Sagitta.

0300: Marco Polo Mission Commander Hernandez declares the maneuver complete. The crew can leave their acceleration stations and resume normal activity.

December 4

The Interstellar Vehicle Marco Polo officially departed Earth on its voyage to Ilmatar today. At 1431 the spacecraft performed a 10-minute main engine burn, putting it on course for an encounter with the Moon in three days. Marco Polo will swing around the Moon, gaining velocity from the encounter and putting it on a path aimed directly at the constellation Sagitta, where Ilmatar is located.

December 3

The Interstellar Vehicle Marco Polo undocked from the Aquarius Orbital Fuel Depot at 1134 today, and performed maneuvers to shift the inclination of its orbit in preparation for tomorrow's Trans-Lunar Insertion burn.

December 2

The crew of the Interstellar Vehicle Marco Polo spent today transferring liquid hydrogen propellant, compressed nitrogen, and reserve oxygen from the Aquarius Orbital Fuel Depot to the Marco Polo. The procedure began at 0430 GMT and was complete by 1950. The operation transferred more than 20,000 kilograms of hydrogen, 1000 kilograms of nitrogen, and 4000 kilograms of oxygen to the Polo — more than half the stored material aboard the Aquarius. A Karavan robot tanker is scheduled to replentish the Aquarius in January.

During the operation, crew members Martha Okome and Patrick Ryan conducted a media interview at 1330 GMT, during which they described their EVA to remove the stray tether blocking the Aquarius docking collar. According to Okome, the tether was apparently secured improperly during the refueling operation for the Interstellar Vehicle Meriwether Lewis in August.

December 1

Today the Interstellar Vehicle Marco Polo attempted to dock with the Aquarius Orbital Fuel Depot. When an obstacle was discovered, the docking was postponed. After an Extra-Vehicular Activity by two Polo crew resolved the problem, the two spacecraft successfully docked.

0115 GMT: Main engine burn for orbital circularization. At this point Polo is 3 kilometers from Aquarius.

0254: Main radiator panels retracted.

0434: Polo is now less than 1 kilometer from Aquarius. Terminal docking maneuvers begin.

0505: Orbital Rendezvous Pilot Shima aborts the docking maneuver when the Polo's external camera reveals a loose tether obstructing the docking collar on Aquarius.

0525: After consultation with mission control, Mission Commander Hernandez decides to pull back to a safe distance and prepare for an EVA using the two Personal Maneuvering Device (PMD) packs aboard the Polo.

0530: Main radiator panels deployed.

1148: Interstellar Drive Specialist Martha Okome and Payload Specialist Patrick Ryan enter the airlock in their EVA suits.

November 29

Interstellar Vehicle Marco Polo powered up at 0400 GMT this morning, the first step in the voyage to Ilmatar scheduled one week from today. The crew are transferring their personal belongings from the International Space Station to the Marco Polo — which will give both the Ilmatar Expedition IIIb crew and the Station staff much more "elbow room."

At 1600 GMT the joint crew will have a small party to wish the Expedition IIIb members a safe journey. Friends and family members on Earth will be able to participate via video link.

November 27

The crew of Ilmatar Expedition IIIb are taking a day off after successfully transferring all the equipment to the Marco Polo for their upcoming voyage to Ilmatar.

At 1500 GMT, Mission Commander Jorge Hernandez conducted a "video town meeting" with students from over a dozen nations. Mr. Hernandez answered questions from the students, discussed what interstellar travel is like, and took the camera on a tour of the Marco Polo.

November 25

The crew of the International Space Station and the visiting crew of Ilmatar Expedition IIIb celebrated Thanksgiving today, with a meal sent up aboard the Pegasus spaceplane five days ago.

The menu included roast turkey breast with gravy, cornbread stuffing, cranberry compote, mashed sweet potatoes, tamales, green beans, cabbage rolls, and pumpkin soup. Dessert featured a selection of pies provided by Food Network celebrity chefs (see link).

The day was only a partial holiday for the crew, however. Equipment transfer operations between the Karavan robot freighter and the Interstellar Vehicle Marco Polo continued during the morning, and after the meal the Station crew took time to conduct experiments using the Swedish DLRM module.

November 22

The crew of Ilmatar Expedition IIIb began the process of transferring equipment from the Russian Karavan unmanned freighter to the Marco Polo. In addition to scientific experiments and personal gear, the expedition will transport food and other consumables for the crew of Hitode Station on Ilmatar.
