Russia is building its own space station to launch in 2025 amid concerns the ISS is becoming too unreliable and ‘endangers the life of the crew’

By Ryan Morrison and Will Stewart

  • The Russian space agency Roscosmos declared the ISS unsafe and a risk to life
  • They are launching a new station within the next four years in low Earth orbit
  • This includes a ‘tourist’ module with room for up to four visitors from the Earth
  • It comes amid increasing tensions between Russia and the West 

Russia could withdraw from the International Space Station in 2025 and launch its own facility over concerns the ISS is becoming too unreliable, Roscosmos says. 
Dmitry Rogozin, chief of the Russian space agency said work has already begun on the first module of a new station, expected to go into orbit early in 2025. 

A top Kremlin official warned that ‘disaster’ was looming for the ISS, putting the lives of crew members at risk due to its age – by 2025 is will be 27 years old and was originally designed to last between 15 and 30 years, according to NASA.

DARPA Taps Blue Origin for Nuclear-Powered Rocket

By Ryan Whitwam 

Blue Origin, the private spaceflight firm founded by Amazon billionaire Jeff Bezos, is still trying to get its New Shepard rocket ready for commercial launches, but it just accepted a contract to design something new. The contracts from the Pentagon’s Defense Advanced Research Projects Agency (DARPA) direct Blue Origin, as well as Lockheed Martin and General Atomics, to design a nuclear thermal propulsion system that could accelerate human spaceflight—literally. 

Our current rocket technology relies mostly on chemical power, such as the liquid-fueled engines on a Falcon 9 or the upcoming SLS. These rockets have very high thrust, but they’re less efficient than electrically powered engines. Missions that need to travel a very long distance often use electric propulsion such as ion engines because they can remain active for long periods at low thrust. So, they’re efficient but slower. 

A nuclear rocket engine could offer unique advantages by using a small reactor to heat and accelerate fuel. That could theoretically give a nuclear thermal rocket high thrust like chemical rockets and high efficiency like electric ones. The agency calls this the Demonstration Rocket for Agile Cislunar Operations (DRACO) program, and these first awards cover just Phase 1 of the program, which is expected to last 18 months.

The US plans to put a nuclear-powered rocket in orbit by 2025

Nuclear thermal rockets could be more manoeuvrable in space

By  David Hambling

The US is taking steps to put a nuclear-powered rocket in orbit by 2025, paving the way for navigation in space to become much easier.

The Defense Advanced Research Projects Agency (DARPA) plans to turn the long-studied concept of a nuclear thermal rocket into a reality. The technology isn’t powerful enough to launch a rocket from Earth, but could give a spacecraft propulsion for an extended period once in space. This would make it ideal for prolonged manoeuvring in orbit or in deep-space missions requiring acceleration and deceleration.



Virgin Galactic debuts its first third-generation spaceship, ‘VSS Imagine’

CEO Michael Colglazier talks about building a consumer space brand

By Darrell Etherington

Commercial human spaceflight company Virgin Galactic has unveiled the first-ever Spaceship III, the third major iteration of its spacecraft design. The first in this new series is called “VSS (Virgin SpaceShip) Imagine,” and will start ground testing now with the aim of beginning its first glide flights starting this summer. VSS Imagine has a snazzy new external look, including a mirrored wraparound finish that’s designed to reflect the spacecraft’s changing environment as it makes its way from the ground to space — but more importantly, it moves Virgin Galactic closer to achieving the engineering goals it requires to produce a fleet of spacecraft at scale.

I spoke to Virgin Galactic CEO Michael Colglazier about VSS Imagine, and what it represents for the company.

“We can build these at a faster pace,” he explained. “These are still relatively slow, versus what we want in our next class of spaceships. But what we do expect to have here is, we’ve taken all the learnings from [VSS] Unity, and built-in what we need to do so that we can turn these ships at a faster pace, because obviously, the number of flights we can do is the product of how many ships you have, and how quickly you can turn them.”

Seattle-based Spaceflight Inc. says it’s won a contract to handle the launch logistics for a pair of NASA satellites that will study the factors behind atmospheric drag.

The twin CubeSats for a mission known as Low-Latitude Ionosphere / Thermosphere Enhancements in Density, or LLITED, are to be lofted into orbit by a SpaceX Falcon 9 rocket around the end of this year. That launch that will mark the first use of Spaceflight’s Sherpa-LTC orbital transfer vehicle, also known as an OTV or space tug.

In January, a different type of Spaceflight space tug, the Sherpa-FX, successfully deployed more than a dozen spacecraft after a Falcon 9 launch. The Sherpa-LTC represents a step above the FX because it has its own in-orbit propulsion system.

The chemical-based thruster system, built for Spaceflight by Benchmark Space Systems, makes it possible for the Sherpa-LTC to shift between different orbital locations. Spaceflight’s mission plan calls for an initial round of satellite deployments, followed by a maneuver that will set the Sherpa up for deploying the LLITED satellites in a different orbit.

“Spaceflight’s full-service offering with our portfolio of Sherpa OTV vehicles greatly increases the scientific opportunities for NASA, universities, and other organizations that require deployments to non-traditional orbital destinations,” Valerie Skarupa, director of government business development for Spaceflight Inc., said in a news release.

Yet another type of OTV, the Sherpa-LTE, will soon make its debut with an electric propulsion system.

British start-up lands state backing to build interplanetary plasma thrusters

The new technology could dramatically improve satellite propulsion and be used to advance space travel

By Michael Cogley

A British start-up that is developing interplanetary plasma thrusters to propel satellites through space has received government funding.

Magdrive, which is based in the Harwell Campus near Oxford, has been granted £64,200 to develop its tech as part of a funding round from the UK Space Agency.

The global space propulsion market is already worth around $5.8bn (£4.15bn) but has been tipped to grow to $19.3bn by 2027. Growth in the sector is likely to be driven by demand for lost-cost small satellites, which can be used for anything from communications to data gathering.

Magdrive, which was founded in 2019, has built a thruster for the satellites that will allow them to move in space and navigate space debris.

The plasma thrusters, which were developed alongside Rocket Engineering, are around the size of a can of coffee. 

The company, which closed a £1.4m seed round in December, claims its technology will allow satellite companies to operate on completely different business models. Advertisement

Magdrive claims its plasma thruster burns 100 times hotter than that of a rocket with the outlay contained by a magnetic field.

In a plasma state, the propellant becomes highly electrically reactive by moving through magnetic coils. This hot plasma exhaust provides the thrust.

The technology has the potential to replace existing electrical and chemical alternatives, which face problems around thrust and efficiency.

The World’s First Space Hotel to Open in 2027

The team working on Voyager Station hopes to partner with SpaceX in its aim to send passengers to the first-ever space hotel.

By Nick Mafi

The Voyager Station, which would accommodate 280 guests, aims to be the first commercial space hotel upon completion

Those of us making grand postpandemic travel plans might want to consider the final frontier as a destination. That’s because Orbital Assembly Corporation, a new construction company run by former pilot John Blincow, is planning to open a luxury space hotel by 2027. Voyager Station, as it’s being called, would accommodate 280 guests and 112 crew members while aiming to be the first commercial space hotel, upon completion.

“We’re trying to make the public realize that this golden age of space travel is just around the corner. It’s coming. It’s coming fast,” Blincow told CNN in an interview. Golden age indeed, as space tourism has piqued the interest of such visionaries as Richard Branson and Elon Musk. And it’s the latter Blincow and his team hope to partner with in the near future. “We cannot call [Musk’s] SpaceX our partner, but in the future we look forward to working with them,” Blincow said at a recent live, asking the viewers to “hang tight.”

Space Race: China to Launch New Space Station; Trains Astronauts for Crewed Flights

The central module for China’s proposed orbital space station has passed a flight approval examination. It will launch in the coming months, kicking off a whirlwind of major missions for the region.

IN SPACE – MAY 23: In this handout image provided by the European Space Agency (ESA) and NASA, the International Space Station and the docked space shuttle Endeavour orbit Earth during Endeavour’s final sortie on May 23, 2011 in Space. Italian astronaut Paolo Nespoli captured the first-ever images of an orbiter docked to the International Space Station from the viewpoint of a departing vessel as he returned to Earth in a Soyuz capsule.

China Manned Space, the world’s human spaceflight agency, announced on January 14 as the country prepares to begin work on its own three-module space station.

The Tianhe central module, which means “harmony of the heavens,” will be the primary living quarters for three-person crews visiting for up to six months.

Following the completion of the space station and the establishment of a national space laboratory, a number of subsequent flight missions will be carried out as planned.

Kentucky firm plans orbital mini space station in two years

by Paul Brinkmann

A Kentucky space firm that conducts science experiments on the International Space Station has plans to launch its own miniature, automated orbital research platform in about two years.

Lexington-based Space Tango has small research containers, or CubeLabs, on the space station. Bustling business and growing need for such experiments in microgravity led the company to plan its own space station, founder and CEO Twyman Clements said.

“As the scale of our business grows across a number of uses, having a dedicated spacecraft for manufacturing is the way to go,” Clements said in an interview Friday.

He declined to say how much the company would spend on the project or how much each spacecraft might cost.

A team of researchers at the University of Pennsylvania are trying to figure out if we can send robots that are made out of ice to another planet, IEEE Spectrum reports.

The idea is to create a robot design that can leverage local resources to repair itself in case it ever breaks down.

As detailed in a new paper presented at the IEEE/RSJ International Conference on Intelligent Robots and Systems, the researchers looked a variety of ways of creating robots out of ice by using both additive and subtractive manufacturing processes.


Scientists discover a superhighway network to travel the solar system

Shane McGlaun 


Researchers have discovered what they describe as a new superhighway network to travel the solar system much faster than previously thought possible. Scientists say that these routes can push comets and asteroids close to the distance between Jupiter and Neptune in under a decade. The speedy paths can also move comets and asteroids 100 astronomical units in less than a century.

It’s possible these superhighway networkscould be used to send spacecraft to the far reaches of the planetary system relatively quickly. Now that these networks have been discovered, they can also be used to monitor and understand near-Earth objects that might impact our planet. Researchers have observed the dynamical structures of these routes, forming a connected series of arches inside something known as space manifolds extending from the asteroid belt to Uranus and beyond.

The “œcelestial autobahn” can act over several decades instead of hundreds of thousands or millions of years that usually go along with solar system dynamics. Jupiter is linked to the most conspicuous arch structures, and the strong gravitational forces exerted. The population of Jupiter-family comets, which have orbital periods of 20 years, and small solar system bodies known as Centaurs are controlled by manifolds on “unprecedented timescales.”
