NASA is testing a 3D moon dust printer on the International Space Station – Dazed

Published

 on


When a spacecraft docked with the International Space Station (ISS) this week, it was carrying with it some very important earthly cargo – a 3D printer that uses moon dust to make solid materials.

The Cygnus spacecraft, developed by US aerospace company Northrop Grumman, delivered the printing system which is designed to revolutionise future missions to the moon by enabling the creation of equipment on the celestial body itself, rather than having to continually fly out heavy, and very expensive, loads.

Research into the use of moon dust – or regolith as it is known scientifically – as a construction material for 3D printing has been ongoing for many years, and now scientists are about to test its ability to produce under zero-gravity conditions onboard the ISS.

As real samples are very precious and rare, the printer will use a human-made “moon stimulant”, a compound similar enough in make-up to lunar regolith to warrant testing. Redwire, the company behind the printer, says that the device can be used to create small fixtures and fittings, but added that it could potentially stretch to printing larger parts like landing pads, roads, or even habitats on the lunar surface.

NASA has made no secret of its ambitions for the technology, suggesting it could even be used to streamline the process of humans becoming an interplanetary species. The space agency has said it intends to look further into the possibility of 3D printing settlements on Mars.

Space telescopes capture asteroid strike – CTV News

Published

CAPE CANAVERAL, Fla. –

The world now has stunning new photos of this week’s asteroid strike, the first planetary defence test of its kind.

NASA on Thursday released pictures of the dramatic event taken by the Hubble and Webb space telescopes.

Telescopes on all seven continents also watched as NASA’s Dart spacecraft slammed Monday into the harmless space rock, 7 million miles (11 million kilometres) from Earth, in hopes of altering its orbit.

Scientists won’t know the precise change until November; the demo results are expected to instill confidence in using the technique against a killer asteroid headed our way one day.

“This is an unprecedented view of an unprecedented event,” Johns Hopkins University planetary astronomer and mission leader Andy Rivkin said in a statement.

All these pictures will help scientists learn more about the little asteroid Dimorphos, which took the punch and ended up with a sizable crater. The impact sent streams of rock and dirt hurling into space, appearing as bright emanating rays in the latest photos.

The brightness of this double asteroid system — the 525-foot (160-metre) Dimorphos is actually the moonlet around a bigger asteroid — tripled after the impact as seen in the Hubble images, according to NASA.

Hubble and Webb will keep observing Dimorphos and its large companion Didymos over the next several weeks.

The US$325 million Dart mission was launched last year. The spacecraft was built and managed by Johns Hopkins’ Applied Physics Laboratory in Laurel, Maryland.

3 Russian cosmonauts return safely from Intl Space Station – Lethbridge News Now

MOSCOW (AP) — Three Russian cosmonauts returned safely Thursday from a mission to the International Space Station.

The Soyuz MS-21 spacecraft carrying Oleg Artemyev, Denis Matveyev and Sergey Korsakov touched down softly at 4:57 p.m. at a designated site in the steppes of Kazakhstan, 150 kilometers (90 miles) southeast of the city of Zhezkazgan.

The trio had arrived at the space station in March. For Artemyev, the mission marked a third space flight, bringing his total time spent in orbit to 561 days. Matveyev and Korsakov each logged 195 days on their first missions.

As the Soyuz capsule was descending, using a big striped red-and-white parachute under clear skies, Artemyev reported to Mission Control that all members of the crew were feeling fine.
