Greenhouses Probably won’t Work on Mars Because of Cosmic Radiation. Even the Plants Will Have to Live Underground

Mars is a lifeless wasteland for more than one reason.  Not only are the temperatures and lack of water difficult for life to deal with, the lack of a magnetic field means radiation constantly pummels the surface.  If humans ever plan to spend prolonged periods of time on the red planet, they’ll need to support an additional type of life – crops.  However, it appears that even greenhouses on the surface won’t do enough to protect their plants from the deadly radiation of the Martian surface, at least according to a new paper published by researchers at Wageningen University and the Delft University of Technology.

Musk Says That Refueling Starship for Lunar Landings Will Take 8 Launches (Maybe 4)

The fight over who gets to take the Artemis astronauts back to the Moon continues! It all began when NASA announced that they had awarded the contract for its Human Landing System (HLS), the reusable lunar lander that would ferry the Artemis III astronauts to the lunar surface. This decision did not sit well with the other two finalists, Blue Origin and Dynetics, who appealed the decision because NASA was showing “favoritism.”

What is the speed of light?

The speed of light puts a speed limit on matter, lets us peer back into the history of our universe, and has deep implications for physics and space travel.

You can Tell how big a Black Hole is by how it Eats

Black holes don’t emit light, which makes them difficult to study. Fortunately, many black holes are loud eaters. As they consume nearby matter, surrounding material is superheated. As a result, the material can glow intensely, or be thrown away from the black hole as relativistic jets. By studying the light from this material we can study black holes. And as a recent study shows, we can even determine their size.

Ingenuity Sees Perseverance From Above

Where’s Waldo (or Where’s Wally) is a very popular book series for all ages.  One way to make it potentially more interesting is to adapt it to interplanetary exploration by searching for a Martian rover in a picture taken from a Martian helicopter.  Ingenuity took a picture on its eleventh flight that would be a worthy addition to any interplanetary search game – in this image, the goal is to find Perseverance.

2024 Artemis Landings Could Slip Because of a Lack of Spacesuits. Musk Offers to Develop Them

In March of 2019, NASA was directed to develop all the necessary equipment and planning to send astronauts back to the Moon by 2024. This plan, officially named Project Artemis, was part of an agency-wide shakeup designed to ensure that the long-awaited return to the Moon takes place sooner than NASA had originally planned. In accordance with their “Moon to Mars” framework, NASA hoped to assemble the Lunar Gateway first, then land astronauts on the surface by 2028.
