TAMPA, Fla. — Denver-based Voyager Space Holdings, which has been buying businesses to build a vertically integrated space exploration company, has appointed former NASA administrator Jim Bridenstine to chair its advisory board.
It is the second corporate announcement in a week for Bridenstine, who joined satellite operator Viasat’s board of directors April 1.

Lunar Gateway will maintain its orbit with a 6 kW ion engine
Tuesday, 06 April 2021 12:12 Write a comment
When NASA sends astronauts back to the moon as part of the Artemis Program, they will be taking the long view. Rather than being another "footprints and flags" program, the goal is to create a lasting infrastructure that will ensure a "sustained program of lunar exploration." A major element in this plan is the Lunar Gateway, an orbital habitat that astronauts will use to venture to and from the surface.
The first step in establishing the Gateway is the deployment of two critical modules—the Habitation and Logistics Outpost (HALO) and the Power and Propulsion Element (PPE). According to a recent update, NASA (along with Maxar Technologies and Busek Co.) recently completed a hot-fire test of the PPE propulsion subsystem—the first of many that will ensure that the PPE and HALO will be ready for launch by 2024.
This propulsion subsystem is a cluster of Hall effect thrusters (aka ion engines), which use electromagnetic fields to accelerate ionized gas through engine nozzles to generate thrust. In this case, the engine system is a 6-kilowatt solar electric propulsion (SEP) concept that incorporates Maxar-built electronics and a xenon feed system with four Busek-built BHT-600 thrusters.

Nagoya University scientists in Japan have demonstrated how DNA-like molecules could have come together as a precursor to the origins of life. The findings, published in the journal Nature Communications, not only suggest how life might have begun, but also have implications for the development of artificial life and biotechnology applications.

Sixty years after he became the first person in space, there are few figures more universally admired in Russia today than Soviet cosmonaut Yuri Gagarin.
His smiling face adorns murals across the country. He stands, arms at his sides as if zooming into space, on a pedestal 42.5 metres (140 feet) above the traffic flowing on Moscow's Leninsky Avenue. He is even a favourite subject of tattoos. From Sputnik-1 to Sputnik V: Russian scientific achievements

Sixty years after the Soviet Union made history by launching Yuri Gagarin into space on April 12, 1961, Russia continues to have lofty extraterrestrial ambitions, but its ability to realise them is more down to earth.

Emily Ury remembers the first time she saw them. She was heading east from Columbia, North Carolina, on the flat, low-lying stretch of U.S. Highway 64 toward the Outer Banks. Sticking out of the marsh on one side of the road were not one but hundreds dead trees and stumps, the relic of a once-healthy forest that had been overrun by the inland creep of seawater.

The rocket engine with one of the most storied histories in spaceflight, the RS-25, is returning to space for a second act - this time to send humans on the Artemis missions to explore the Moon.
As the space shuttle main engine, the RS-25 has a proven record of launching 135 missions spanning over three decades. At the end of the shuttle program in 2011, 16 RS-25 engines that helped build Burnt-out comet covered with talcum powder

The world's first ground-based observations of the bare nucleus of a comet nearing the end of its active life revealed that the nucleus has a diameter of 800 meters and is covered with large grains of phyllosilicate; on Earth large grains of phyllosilicate are commonly available as talcum powder. This discovery provides clues to piece together the history of how this comet evolved into its curre
