Elon Musk’s concept of solving traffic congestion by digging networks of tunnels may have a fan in Los Angeles Mayor Eric Garcetti.

Speaking about the city’s transit issues Sunday morning on ABC 7‘s “Eyewitness Newsmakers,” Garcetti mentioned the possibility of tunneling: “Like many other cities have, I’d love to see maybe even with the new tunneling technology that people like Elon Musk is looking at, whether we could have a quick and direct route from LAX to Union Station.”

Derelict satellites could in future be grappled and removed from key orbits around Earth with a space tug using magnetic forces.

This same magnetic attraction or repulsion is also being considered as a safe method for multiple satellites to maintain close formations in space.

Such satellite swarms are being considered for future astronomy or Earth-observing missions – if their relative positions can stay stable they could act as a single giant telescope.

The term “moonshot” is sometimes invoked to denote a project so outrageously ambitious that it can only be described by comparing it to the Apollo 11 mission to land the first human on the Moon. The Breakthrough Starshot Initiative transcends the moonshot descriptor because its purpose goes far beyond the Moon. The aptly-named project seeks to travel to the nearest stars.

The brainchild of Russian-born tech entrepreneur billionaire Yuri Milner, Breakthrough Starshot was announced in April 2016 at a press conference joined by renowned physicists including Stephen Hawking and Freeman Dyson. While still early, the current vision is that thousands of wafer-sized chips attached to large, silver lightsails will be placed into Earth orbit and accelerated by the pressure of an intense Earth-based laser hitting the lightsail.

A 3D printer that could re-create itself from lunar material is in development at a university in Canada.

The technology could one day enable humans to 3D-print lunar bases, as well as conduct in-space manufacturing of satellites and solar shields on the moon that could help fight global warming, according to Alex Ellery, an associate professor in the Department of Mechanical and Aerospace Engineering at Carleton University in Ottawa, who is leading the project.

“I believe that self-replicating machines will be transformative for space exploration because it effectively bypasses launch costs,” Ellery told Space.com. [How Moon Bases and Lunar Colonies Work (Infographic)].

The researchers think this unseasonably warm air was due primarily to the powerful 2015–2016 El Niño. As they write in their paper, the El Niño climate pattern, which starts with high sea surface temperatures in the equatorial Pacific, tends to promote the advection of high pressure air masses over this part of Antarctica. But they’re not sure—after all, the comparably-strong 1997–98 El Niño event didn’t cause widespread melting in West Antarctica. And although the data points to a correlation between El Niño and melty ice in West Antarctica, that doesn’t necessarily imply causation.

300,000 square miles is nearly twice the area of California. It’s difficult to visualize a space that vast, but go ahead and give it a try. Now, imagine this California plus-sized chunk of land is covered in thousands of feet of ice. Then, all of a sudden, that frozen fortress becomes a wading pool.

In January 2016, over the course of just a few weeks, a 300,000 square mile chunk of the West Antarctic ice sheet started turning to slush, in one of the largest melt-outs ever recorded. Scientists with the ARM West Antarctic Radiation Experiment (AWARE), who reported the epic defrost in Nature Communications last week, believe it was related to the 2015–2016 El Niño. Troublingly, they think massive melts like this could be a harbinger of the future—but more research is needed before we can be sure.
