Lockheed Martin has revealed plans to set up a ‘Mars base camp’ orbiting the red planet — and says it hopes to launch it within ten years.

Using NASA’s Orion spacecraft as the command deck, the orbiting outpost could give astronauts the ability to operate rovers and drones on the surface in real time, helping us better understand the Red Planet and plan for manned missions.

‘The time is now,’ Lockheed Martin said in a video revealing the project at the International Astronautical Congress (IAC) in Adelaide, Australia, where it also showed off a lander that could eventually take astronauts form the station to the red planet’s surface.

Russia and the United States have agreed to cooperate on a NASA-led programme to build the first lunar space station, part of a long-term project to send humans to Mars.

The US space agency said earlier this year that it was exploring a programme called the Deep Space Gateway, a multi-stage project to push further into the solar system.

The project envisages building a crew-tended spaceport in lunar orbit that would serve as a “gateway to deep space and the lunar surface,” NASA has said.

A recent research discussion paper “The Andromeda Study: A Femto-Spacecraft Mission to Alpha Centauri” discusses options for a 50 year (at 0.1c) one-way, fly-by, exploration trip to our nearest stellar neighbour, Alpha Centauri. In the paper the authors (Andreas M. Hein, Kelvin F. Long, Dan Fries, Nikolaos Perakis, Angelo Genovese, Stefan Zeidler, Martin Langer, Richard Osborne, Rob Swinney, John Davies, Bill Cress, Marc Casson, Adrian Mann, Rachel Armstrong) discuss the challenges and present possible solutions using current science and technology.

Deep space travel is circumscribed by an interactive conflict. For those that may want to make extended space journeys, the distances are remarkably great, and our spaceships are slow. These combine to make the trip times exceedingly long. When one attempts considering interstellar transit, you quickly realize that a normal human life span prevents an adult from ever even returning to Earth. Yet even for missions to nearby Mars travel times are projected to take about eight months one-way.

We cannot do anything about the physical distances, nor can we expect much more performance out of current chemical rockets for projected near-term transports within the solar system. While there are projected improvements in velocity in the future through introduction of fission propulsion, fusion-drive rockets, or other exotic space transport engines, space travel will continue to require long transit times. Even if one is able to exploit velocity-enhancing tricks like gravity-assist planetary flybys, deep space trips to, say, mineral-rich asteroids in the main belt will still be measured in years.

So, for transporting people around our solar system, the fundamental question has and continues to be whether anything practical can be done about adjusting the impacts for the humans on board. More precisely, are there practical near-term methods to improve space transport human system design factors that could allow us to create more cost-efficient spaceships and improve the safety to passengers and crew during these long voyages?

Four decades ago, Voyager 1 and 2 began their journey to the stars. When will humans follow them?

Editor’s note: This is a companion piece to the science fiction short “Dark was the night, and cold the ground,” published Thursday in Terraform.

As the summer of 1977 drew to a close, twin siblings bid farewell to Earth to explore the ultimate frontier. They wrote back often, and sent lots of beautiful postcards, so that everyone at home could keep up with their adventures. Each of them carried an identical golden time capsule, filled with the sights and sounds of the world they left behind, so they could act as ambassadors to any other lifeforms they might encounter on their endless journey.

China and Russia are set to sign a milestone agreement in October on joint space exploration from 2018 to 2022, sending manned missions to the Moon for the first time. The bilateral agreement will cover five areas including lunar and deep space exploration, developing special materials, collaboration in the area of satellite systems, Earth remote sensing, and space debris research. This is the first bilateral agreement to cover a partnership spanning five years. It is to be signed against the background of space exploration race the US is trying to win, so the two partners decided to join the efforts. In February, the Trump administration asked NASA to look into the possibility of manning a heavy-lift rocket mission, expected to be launched in 2018, setting the stage for a human return to the Moon.

Russia’s Glavkosmos space launch operator is also working with Chinese partners on joint experiments aboard the International Space Station (ISS). China was interested in buying the world’s most powerful Russian-made RD rocket engines produced by Energomash while Russian Space Systems showed interest in Chinese electronic technology.

The first module of China’s space station Beijing is expected to be launched in 2018. The project is to be completed in 2022. According to the plans, a Chinese mission will be sent to Mars in 2020 to land a robot vehicle for scientific research. Last year, Beijing put into operation the world’s largest radio telescope half a kilometer (0.3 miles) in diameter. In 2014, China caught up with Russia having launched about the same number of satellites – 117 (72% increase in 2011–14). Russia had 118 launched by the time (the number increased by 20% during the same period).

Femto-spacecraft could travel to alpha centauri.

Earth’s nearest exoplanet twin orbits a star about four light years from here. Now scientists say it’s possible to visit this system in our lifetimes by propelling a tiny spacecraft on the tip of a laser beam.
