#科技头条#【俄罗斯宇航员投放世界第一颗3D打印卫星】昨日,俄罗斯宇航员在国际空间站的太空行走期间,投放了世界上第一颗3D打印卫星。该小型卫星由托木斯理工大学制造,外壳和电池组由3D打印机制成,长度不超过1到2英尺。它能释放常规的卫星信号,以及各种语言的对地球的问候,预计将进行5到6个月的轨道航行。

Russian cosmonauts release the world's first 3D printed satellite during spacewalk on the ISS

  • Satellite released during spacewalk is first made almost entirely by 3D printer
  • It contains regular electronics and greetings to Earth in variety of languages
  • The other satellites deployed Thursday have traditional spacecraft parts

Spacewalking cosmonauts set free the world's first satellite made almost entirely with a 3-D printer on Thursday.

In total, Russians Fyodor Yurchikhin and Sergey Ryazanskiy ended up releasing five nanosatellites by hand.

One by one, the tiny craft - no more than 1 to 2 feet in size - tumbled safely away from the International Space Station.

The exterior casing of the first one tossed overboard was made with a 3-D printer.

So were the battery packs inside.

Researchers want to see how 3-D-made parts weather the space environment.

The 3-D satellite contains regular electronics.

It also holds greetings to planet Earth in a variety of languages, courtesy of students at Siberia's Tomsk Polytechnic University, where the satellite was made.

The other satellites deployed Thursday have traditional spacecraft parts.

Each weighs just 10 to 24 pounds.

They're expected to orbit for five to six months.

One commemorates the 60th anniversary of the world's first satellite, Sputnik 1, launched Oct. 4, 1957, by the Soviet Union.

Another pays tribute to Russia's father of rocketry, Konstantin Tsiolkovsky.

He was born 160 years ago next month.

The remaining two small satellites involve navigation and other experiments.

Yurchikhin and Ryazanskiy completed the satellite releases within an hour of venturing outside.

Barely a minute passed between a few of the launches.

The rest of the chores took longer than expected, however, and Russia's Mission Control outside Moscow sent the planned six-hour spacewalk into overtime.

'We will have actually some grounds to get drunk today, I think,' one of the cosmonauts joked in Russian.

A flight controller replied that he'd do it for them.

The cosmonauts also collected science experiments from outside their 250-mile-high home.

Three Americans and one Italian also live on the space station.
