Rocket Lab’s Electron booster reaches orbit

Electron lifting off

New Zealand officially joins the rank of spacefaring nations as Rocket Lab's Electron booster reached orbit in the first successful commercial space launch in the southern hemisphere. On January 21 at 1:43 GMT, the composite-bodied, two-stage rocket lifted off from Rocket Lab's Launch Complex 1 located on the tip of the Māhia Peninsula, between Napier and Gisborne on the east coast of the North Island of New Zealand carrying a payload of mini satellites, which it successfully delivered to Earth orbit.

Propellantless propulsion system could keep satellites in orbit, reduce space junk

This system could be useful for satellites orbiting the Earth such as the Sentinel-1

One of the main factors limiting the life of satellites is how much propellant they can carry to execute orbital corrections. Now scientists at the Universidad Carlos III de Madrid (UC3M) and the Universidad Politécnica de Madrid have come up with a propellantless propulsion system that also doubles as an electric generator. Using the Earth's magnetic field interacting with a two-km (1.24-mi) long aluminum tether, the system could be used to dispose of space debris and boost the orbit of the International Space Station (ISS).

In photos: Trucks and SUVs give the 2018 Detroit auto show some serious brawn

Celebrating the introduction of the all-new G-Class and the timelessness of Mercedes' rugged 4x4, the sculpture ...

As much as it is a great car show, the 2018 North American International Auto Show might just be more of a truck and 4x4 show. In a country where pickup trucks rule, it's no small story when each of the Big 3 shows an all-new pickup truck, especially when one of those pickups has been entirely absent from the market for the better part of a decade. Not to be outdone, each of Japan's Big 3 is wowing attendees with a wild concept SUV or two. And before you even get through the front door, you're hit in the eyes by an orange hunk of resin with a classic Mercedes G-Wagen trapped inside. Trucks and SUVs are definitely a big highlight, if not the big highlight.
