Could we turn the sun into a gigantic telescope?

NeRD

We have some incredibly powerful telescopes that have given us spectacular views of the cosmos and allowed us to look back to the early days of the universe. These observatories, such as the James Webb Space Telescope (JWST), are amazing feats of engineering that have required billions of dollars and decades of work.  But what if we could access an even better telescope that already exists? This wouldn’t be a typical telescope. It wouldn’t even come with a lens. But it would be by far the most powerful telescope we’d…

SpaceX’s private Polaris Dawn astronauts splash down to end historic spacewalk mission (video)

NeRD

Polaris Dawn has landed. The historic SpaceX astronaut mission — which conducted the first-ever private spacewalk, among other achievements —returned to Earth today (Sept. 15), splashing down safely in the Gulf of Mexico off the coast of Florida at 3:36 a.m. EDT (0736 GMT). “Polaris Dawn we are mission complete. Thanks for all the big help pulling this mission together,” said mission commander Jared Isaacman after the crew splashed down in the ocean.

Astronauts 3D-print 1st metal part while on ISS

NeRD

ESA scientists have successfully demonstrated 3D printing of a metal part in space for the first time.  3D printing in space poses challenges, as many methods rely on gravity to position materials during the printing process. This is because when creating metal structures, molten metal is often used as part of the filament, or printable medium. In space, its behavior can be unpredictable, which can result in poor-quality objects, as the filament might shift or be placed incorrectly due to the lack of gravitational forces. Scientists therefore had to adapt…

This Week In Space podcast: Episode 128 —Starliner is Back! What Now?

NeRD

Starliner is Back! What Now? – Can Boeing Compete with SpaceX’s Dragons? – YouTube Watch On On Episode 128 of This Week In Space, Rod Pyle and Tariq Malik talk about what’s going on with Boeing’s Starliner CST-100 spacecraft. Starliner is back and, by all accounts, could have returned with its crew had it been necessary. However, with NASA’s “safety forward” approach prevailing, the spacecraft landed uncrewed on September 6, three months after it docked with the International Space Station. Now, the work begins to try to solve the problems-…

Super Harvest Moon lunar eclipse: How to watch online for free on Sept. 17

NeRD

A partial lunar eclipse of September’s Super Harvest Moon is coming, and you can watch online for free. On Tuesday (Sept. 17), the Full Harvest Moon will experience a partial lunar eclipse that will be visible for North and South America (except for Alaska), Europe, most of Africa, western Asia, and parts of Antarctica. This eclipse will take place during a “supermoon,” which will make the moon appear slightly larger in the night sky. This occurs when the moon is slightly closer to Earth, which happens because the moon’s orbit is…

‘We just ran out of time’: Boeing Starliner astronauts on why their spaceship returned to Earth without them

NeRD

Boeing’s Starliner capsule might have been able to finish its mission as planned if time had been on its side. Starliner launched June 5 on its first-ever crewed flight, a trial run that sent NASA astronauts Suni Williams and Butch Wilmore to the International Space Station (ISS). The duo were supposed to live on the orbiting lab for just a week or so, but NASA extended their stay to about three months while studying thruster issues that cropped up during Starliner‘s rendezvous with the ISS. Ultimately, the agency concluded that…
