Cygnus freighter delivers space toilet and more to astronauts on space station

The astronauts aboard the International Space Station just got nearly 4 tons of new supplies, including a $23 million titanium space toilet.

The gear arrived today (Oct. 5) aboard the private robotic Cygnus freighter, which reached the orbiting lab at 5:32 a.m. EDT (0932 GMT). 

NASA astronaut Chris Cassidy, who commands the station's current Expedition 63, grappled the Cygnus with the station's huge robotic arm at that time. The cargo craft was officially bolted into place at 8:01 a.m. EDT (1201 GMT), while the two spacecraft were flying 261 miles (420 kilometers) above the South Pacific Ocean, NASA officials said. By coincidence, the docking occurred at the start of World Space Week 2020, which runs from Oct. 4 to Oct. 10 to celebrate the impact space exploration and technology have on daily life.

Cassidy and his two Expedition 63 crewmates, cosmonauts Ivan Vagner and Anatoly Ivanishin, can now begin unloading the Cygnus, which launched Friday night (Oct. 2) from NASA's Wallops Flight Facility in Virginia with 7,624 lbs. (3,458 kilograms) of cargo on board. 

The supplies include food, hardware, a variety of scientific experiments and the Universal Waste Management System, a pricey new space toilet that will be tested for potential future use in orbit and on the moon.

The Cygnus was built by Virginia-based company Northrop Grumman, which holds a NASA contract to fly robotic resupply missions to the space station. SpaceX has a similar deal, which it fulfills using the cargo version of its Dragon capsule. (SpaceX also holds a NASA commercial crew deal and is preparing to launch four astronauts to the station on Oct. 31).

This Cygnus, named the S.S. Kalpana Chawla after one of the seven astronauts who died in the 2003 space shuttle Columbia disaster, the 13th to reach the International Space Station and the 14th to take flight overall.

The S.S. Kalpana Chawla will remain docked to the station until mid-December. It will then fly freely around Earth for about two weeks, allowing researchers to conduct an onboard fire-safety experiment called Saffire-V. The freighter will then make a suicide dive into Earth's atmosphere, disposing of several tons of astronaut trash in the process.
