The ESA is investigating hibernation technology that could allow astronauts to remain healthy during long-duration missions to Mars and beyond.

A renewed era of space exploration is upon us, and many exciting missions will be headed to space in the coming years. These include crewed missions to the Moon and the creation of permanent bases there. Beyond the Earth-Moon system, there are multiple proposals for crewed missions to Mars and beyond. This presents significant challenges since a one-way transit to Mars can take six to nine months. Even with new propulsion technologies like nuclear rockets, it could still take more than three months to get to Mars.

In addition to the physical and mental stresses imposed on the astronauts by the duration and long-term exposure to microgravity and radiation, there are also the logistical challenges these types of missions will impose (i.e., massive spacecraft, lots of supplies, and significant expense). Looking for alternatives, the European Space Agency (ESA) is investigating hibernation technology that would allow their astronauts to sleep for much of the voyage and arrive at Mars ready to explore.

You are on the PRO Robots channel and today we present to your attention the latest issue of high-tech news. The U.S. military has learned to control more than a hundred robots simultaneously, and the Chinese have created a copy of Boston Dynamics’ BigDog robot, an electronic skin to control robots, and are about to compete with StarLink. For more on this, as well as underwater robots, the perfect robot arm, and other cutting-edge technology, check out our video!

Could a laser send a spacecraft to Mars? That’s a proposed mission from a group at McGill University, designed to meet a solicitation from NASA. The laser, a 10-meter wide array on Earth, would heat hydrogen plasma in a chamber behind the spacecraft, producing thrust from hydrogen gas and sending it to Mars in only 45 days. There, it would aerobrake in Mars’ atmosphere, shuttling supplies to human colonists or, someday perhaps, even humans themselves.

The award brings NASA a step closer to the first robotic round trip to bring samples safely to Earth through the Mars Sample Return Program.

NASA has awarded a contract to Lockheed Martin Space of Littleton, Colorado, to build the Mars Ascent Vehicle (MAV), a small, lightweight rocket to launch rock, sediment, and atmospheric samples from the surface of the Red Planet. The award brings NASA a step closer to the first robotic round trip to bring samples safely to Earth through the Mars Sample Return Program.

“This groundbreaking endeavor is destined to inspire the world when the first robotic round-trip mission retrieves a sample from another planet – a significant step that will ultimately help send the first astronauts to Mars,” NASA Administrator Bill Nelson said. “America’s investment in our Mars Sample Return program will fulfill a top priority planetary science goal and demonstrate our commitment to global partnerships, ensuring NASA remains a leader in exploration and discovery.”

For the third time, SpaceX has installed Super Heavy Booster 4 (B4) on Starbase’s lone orbital launch mount, kicking off preparations for CEO Elon Musk’s upcoming presentation.

In a decision that is difficult to logically explain, however, SpaceX chose to install Super Heavy on the ‘orbital launch mount’ with a crane instead of a complex pair of giant arms explicitly designed to lift, stack, and catch Starship hardware that the company has spent the last several months installing and testing.

This does not make a great deal of sense. One obvious explanation would be that those arms – despite completing multiple lift tests with hundreds of tons of water bags in recent weeks – are not ready for lifting and stacking operations. However, Starbase does not have a crane large enough to lift Starship S20 onto Booster 4, meaning that SpaceX almost certainly intends to use the tower’s arms to do so.

Hopefully, none of the astronauts vying to join the Artemis crewed Moon missions are similarly nyctophobic. If a new NASA image is anything to go on, they’ll need to get over it.

“NASA astronauts are no strangers to extreme environments,” Megan Dean, a NASA spokesperson tells Inverse. Just as well. In a hauntingly beautiful photograph posted on Twitter this week, NASA teases just how extreme the environment may be when NASA astronauts reach the Moon as part of the Artemis III mission, currently slated for 2025.

Artemis III will be the first crewed Moon landing as part of the NASA program to return humans to the Moon. It will be the first such mission since 1972, when Apollo 17 landed astronauts on the Moon for the last time. Artemis III is geared to land in the Moon’s south pole region — an unexplored zone some of which lies in permanent shadow (although other areas are rather bright).
