NASA Tests Autonomous Lunar Landing Technology

In anticipation of many Moon landings to come, NASA is testing an autonomous lunar landing system in the Mojave Desert in California. The system is called a “terrain relative navigation system.” It’s being tested on a launch and landing of a Zodiac rocket, built by Masten Space Systems. The test will happen on Wednesday, September 11th.

The Light Sail is Working… It’s Working!

Good news from The Planetary Society: LightSail 2’s solar sail is functioning as intended. After launching on June 25th, then deploying its solar sail system on July 23rd, mission managers have been working with the solar sail to optimize they way LightSail 2 orients itself towards the Sun. Now The Planetary Society reports that the spacecraft has used its solar sail to raise its orbit.

Skywatcher and Satellite Tracker Photographs US Air Force’s Secret Space Plane in Orbit!

Ever since it started taking to space, there has been a lot of mystery and controversy surrounding the USAF’s X-37B space plane. Despite the fact that this militarized-version of NASA’s orbital vehicle has conducted several spaceflights since its first in 2010, we still have no idea what its true purpose is. But so far, the smart money appears to be on it being an advanced spy plane.

Hoping to gather clues to this question, skywatcher and satellite tracker Ralf Vandebergh of the Netherlands has spent the past few months hunting for this space plane in the night sky. Recently, he was fortunate enough to not only locate the elusive X-37B in the sky but also managed to snap some photographs of it. Given its diminutive size and secretive-nature, this was no small feat!

SpaceIL Scraps its Plans to go Back to the Moon. Instead, it’s Got a New Secret “Significant Objective” for Beresheet 2

Mystery. Secrecy. A Need-To-Know Basis. These are the hallmarks of science. Wait a minute: no they’re not. So what’s with all the mysterious secret objective talk from SpaceIL about Beresheet2?

Deep Space Atomic Clocks Will Help Spacecraft Answer, with Incredible Precision, if They’re There Yet

How do spacecraft know where they are? There’s no GPS out there. Right now, it involves sending a signal to the spacecraft which the spacecraft then sends right back to Earth. The elapsed time reveals the distance.

But on June 24th, that method could be replaced by something much more autonomous.

New Ideas to Reduce Muscle Loss During Spaceflight

One of the obstacles to long space missions is the muscle loss that astronauts suffer from. It’s called atrophy, and NASA says that astronauts can lose up to 20% muscle mass during missions of only 5 to 11 days. This muscle loss affects what are called “anti-gravity muscles,” including calf muscles, the quadriceps and the muscles of the back and neck.

This muscle loss makes it hard for astronauts to complete their tasks, especially when missions to Mars happen. It can also be very dangerous to astronauts, because they’re weakened when they return to Earth. If there are problems during re-entry, and they need to perform any strenuous emergency procedures, that missing muscle could be the difference between life and death.

Europe is Working On a Reusable Space Transport System: Space Rider

The ESA is developing its own spacecraft capable of re-entry into Earth’s atmosphere. The reusable spacecraft is called the Space RIDER (Reusable Integrated Demonstrator for Europe Return), and the ESA says that the Space Rider will be ready for launch by 2022. It’s being designed to launch on the Vega-C rocket from Europe’s spaceport in Kourou, French Guiana.
