SpaceX’s CRS-15 Dragon cargo resupply ship has been attached to the International Space Station. the spacecraft rendezvoused with the orbiting outpost in the early-morning hours of July 2, 2018, and is expected to remain berthed for about a month.

Capture took place at 6:54 a.m. EDT (10:54 GMT) by the 17.6-meter Canadian-built robotic Canadarm2, which was under the control of Expedition 56 NASA astronauts Ricky Arnold and Drew Feustel at the robotics work station in the station’s cupola window. The vehicle was grappled while the station was flying 412 kilometers over Quebec City.

“Looking forward to some really exciting weeks ahead as we unload the science and get started on some great experiments,” Arnold said.

CapCom Pooja Jesrani concurred from Mission Control in Houston and congratulated the crew for “making it look easy.” She added that this was the 30th spacecraft captured using Canadarm2 since the Japanese HTV-1 mission in 2009.

“It’s hard to believe,” Arnold said. “As we were watching Dragon climbing up the R-bar, [we were] just thinking how far we’ve come. It’s quite an accomplishment.”

Several hours later, the arm—this time controlled by ground-based operators—moved the capsule to the Earth-facing port of the Harmony module at the forward end of the ISS where it was carefully positioned for a series of bolts to turn, firmly attaching it to the outpost at 9:52 a.m. EDT (13:52 GMT).

Hauling the science

The rendezvous came about three days after the spacecraft launched from Cape Canaveral, Florida. The pre-dawn launch occurred at 5:42 a.m. (10:42 GMT) June 29, and utilized the final block 4 Falcon 9 rocket.

The vehicle contains some 2,700 kilograms of cargo. Inside Dragon’s pressurized capsule, this includes 205 kilograms of crew supplies, 1,233 kilograms of science investigations, 63 kilograms of spacewalking equipment, 178 kilograms of vehicle hardware, 21 kilograms of computer resources, and 12 kilograms of Russian hardware.

According to NASA, the unpressurized trunk contains the 550-kilogram Earth science instrument called the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station, and a 435-kilogram latching end effector in the event a spare is needed for Canadarm2.

After a month aboard the ISS, the spacecraft is expected to be filled with equipment and experiments to be returned to Earth. Once unberthed in early August, CRS-15 Dragon is expected to slowly drift away from the ISS over several hours, perform a 10-minute de-orbit burn and perform a parachute-assisted splashdown off the coast of Baja California.

Among the science experiments aboard CRS-15 Dragon is a new artificial intelligence computer called the “Crew Interactive MObile companioN”—CIMON (pronounced “Simon”) for short.

Roughly spherical and about the size of a basketball—some 32 centimeters in diameter—CIMON is designed to be an AI assistant for astronauts and cosmonauts in space. 

Developed by Airbus for the German Aerospace Center, the technology demonstrator is expected to explore AI as a way to mitigate crew stress and workload during long-duration spaceflight, according to NASA.

It is expected to be set up and tested by Expedition 56 flight engineer and European Space Agency astronaut Alexander Gerst before the conclusion of his flight in October 2018.

According to Airbus, the whole structure of CIMON is made of plastic and metal that was 3D printed.

Using 12 fans as air jets, the device can move and rotate in any direction and, according to the German Aerospace Center, “turn to an astronaut if it is addressed, not and shake its head, and independently follow the user on command.”

I am a space geek who loves to write about space.

My passion for space ignited when I watched space shuttle Discovery leap to space on October 29, 1998. Today, this fervor has accelerated toward orbit and shows no signs of slowing down. After dabbling in math and engineering courses in college, I soon realized that my true calling was communicating to others about space exploration and spreading that passion.

Currently, I am a senior at Washburn University studying Mass Media with an emphasis in contemporary journalism. In addition to running Orbital Velocity, I write for the Washburn Review and am the Managing Editor for SpaceFlight Insider.
