Update: The Analog-1 experiment was a complete success! Astronaut Parmitano completed all the requirements within the specified time frame (one hour). This test is the first step in validating the teleoperation technology.
NASA has been rather up-front about its desire to send astronauts back to the Moon and on to Mars in the coming years. They are joined by multiple space agencies (such as the ESA, Roscosmos, the CNSA and the IRSO) who also wish to conduct their first crewed missions beyond Earth. However, what is often overlooked is the role teleoperated missions will play in the near-future – where humans and robots explore hand-in-hand.
For example, the ESA has embarked upon a series of experiments collectively named Analog-1, where astronauts control robots from space. Yesterday (Nov. 18th), ESA astronaut Luca Parmitano took control of a robot in the Netherlands from the ISS. This experiment and others like it will help prepare astronauts for future missions that will involve the exploration of hazardous or inaccessible off-world environments.

In the past decade, thousands of planets have been discovered beyond our Solar System. This has had the effect of renewing interest in space exploration, which includes the possibility of sending spacecraft to explore exoplanets. Given the challenges involved, a number of advanced concepts are currently being explored, like the time-honored concept of a light sail (as exemplified by Breakthrough Starshot and similar proposals).
However, in more recent years, scientists have proposed a potentially more-effective concept known as the electric sail, where a sail composed of wire mesh generates electrical charges to deflect solar wind particles, thus generating momentum. In a recent study, two Harvard scientists compared and contrasted these methods to determine which would be more advantageous for different types of missions.

It’s time to update the rules. That’s the conclusion of a panel that examined NASA’s rules for planetary protection. It was smart, at the dawn of the space age, to think about how we might inadvertently pollute other worlds with Earthly microbes as we explore the Solar System. But now that we know a lot more than we did back then, the rules don’t fit.

When a NASA engineer announces a new and revolutionary engine that could take us to the stars, it’s easy to get excited. But the demons are in the details, and when you look at the actual article things look far less promising.

A team of Japanese researchers have used sperm from mice that spent time aboard the International Space Station (ISS) to fertilize female mice back on Earth. While previous research has shown that freeze-dried mouse sperm stored in space can experience radiation damage, these results show that the sperm from live mice may not suffer the same damage.

Picture two tissue box-sized spacecraft orbiting Earth.
Then picture them communicating, and using a water-powered thruster to approach each other. If you can do that, then you’re up to speed on one of the activities of NASA’s Small Spacecraft Technology Program (SSTP.) It’s all part of NASA’s effort to develop small spacecraft to serve their space exploration, science, space operations, and aeronautics endeavors.

Where you can travel in space depends on how much propellant you’ve got on board your rocket and how efficiently you can use it. But there’s a source of free propellant right here in the Solar System – the Sun – which is streaming out photons in all directions. You just need to catch them.
And right now, the Planetary Society’s new LightSail 2 spacecraft is testing out just how well it’ll work.

After months of discussion, the space agencies behind the Lunar Gateway have decided how the space station will orbit the Moon. NASA and the ESA are developing the Lunar Gateway jointly, and the orbital path that it will follow around the Moon is a key part of mission design. It’ll affect all the vital aspects of the mission, including how spacecraft will rendezvous and land at the station.

The 50th anniversary of You-Know-What is coming up and LEGO is getting in on the celebration. The much-beloved company has released a replica of the Apollo 11 Eagle Lunar Lander. The new lander is part of LEGO’s Creator Expert collection.
LEGO teamed up with NASA on this effort, and the model boasts quite a few realistic touches.
