Space Force is About to Launch its Mysterious X-37B Spaceplane Again

There has been quite a bit of buzz in the past few years about the US Space Force (USSF), especially now that they are recruiting! The sixth and youngest branch of the US Armed Forces, Space Force was created in 2019 when the Air Force Space Command (AFSC) was broken off from the US Air Force (USAF) and made into an independent service branch.

There’s been even more buzz about the USAF’s X-37B Orbital Test Vehicle (OTV), a reusable robotic spaceplane whose official purpose is still highly classified! And now, the USAF and the U.S. Space Force have come together to launch the X-37B on its sixth mission (OTV-6). In just two days, this spaceplane will take off from Cape Canaveral Air Force Station in Florida to perform a number of tasks (some of which we know about!)

Finally! InSight’s Mole is Making Slow and Steady Progress

Personnel at NASA and the DLR have been working for months to get InSight’s Mole working. They’re at a disadvantage, since the average distance between Earth and Mars is about 225 million km (140 million miles.) They’ve tried a number of things to get the Mole into the ground, and they may finally be making some progress.

Weekly Space Hangout: May 13, 2020 – Dr. Seth Shostak from the SETI Institute

This week we are pleased to welcome Seth Shostak to the Weekly Space Hangout. Seth is Senior Astronomer and Institute Fellow at the SETI Institute. With degrees in physics and astronomy from Princeton University and Caltech, he has a long history of research in radio astronomy and in the Search for Extraterrestrial Intelligence, or SETI.

Sediments on Mars, Created By Blowing Wind or Flowing Water

The HiRISE (High-Resolution Imaging Science Experiment) instrument on NASA’s Mars Reconnaissance Orbiter (MRO) has given us a steady stream of images of the Martian surface. It’s been in orbit around Mars since March 2006, and has greatly outlived its intended mission length.

One of the latest Hi-PODs, or HiRISE Pictures of the Day, is this one, of sedimentary rock on Mars being eroded away.

Another Starship Success! Raptor Engine Fires for 4 Seconds and Nothing Explodes

Last week, SpaceX passed another milestone in the development of its Starship prototype. This was the crucial engine static fire test, which saw the fourth full-scale Starship prototype (SN4) ignite a fully-integrated Raptor engine for the first time. The successful test took place on Tuesday night (May 5th) at 08:57 PM local time (09:57 PM EDT; 06:57 PM PDT) and saw the Raptor engine ignite and fire for four full seconds.

This “All Terminator” Image of the Moon isn’t Actually Possible to See. But it Sure is Beautiful

“This moon might look a little funny to you, and that’s because it is an impossible scene,” wrote photographer Andrew McCarthy on Instagram.

He was talking about his other-wordly, almost Shakesperean image of the Moon. And that’s because this is an ‘all-terminator’ image.

Time Travel Into The Future Is Totally Possible

Believe it or not, time travel is possible.

In fact, you’re doing it right now. Every single second of every single day you are advancing into your own future. You are literally moving through time, the same way you would move through space. It may seem pedantic, but it’s a very important point. Movement through time is still movement, and you are reaching your own future (whether you like it or not).

Better Tires to Drive on Mars

A future rover on Mars may include shape-shifting capabilities. This innovative tech won’t quite be like the liquid-metal polymorphing robot from “Terminator 2,” but will solve a problem that have plagued previous rovers: wheel wear and tear.

NASA’s Glenn Research Center is now using shape memory alloys (SMA) to build better wheels for driving on Mars.

NASA is Going to Try Manufacturing a Telescope Mirror in Space

Space telescopes are a pretty amazing thing. By deploying an observatory to orbit, astronomers are able to take pictures of the Universe unencumbered by atmospheric disturbance. At the same time, they are very expensive to build, maintain, and launch into space. As the case of Hubble’s flawed mirror demonstrated, a space telescope also has to go through rigorous checks because of how difficult it becomes to service them after launch.

To address this, NASA is investigating the possibility of constructing future space telescopes in space. A key aspect of this involves a manufacturing technique known as Atomic Layer Deposition (ALD), a process where layers of material no thicker than an atom is deposited on a surface and then hardened in place. Now, a team of NASA-supported researchers has been given the chance to test ALD in a microgravity environment (i.e. space!)

Perseverance Rover is Getting Tucked Into its Launch Fairing

NASA's Mars Perseverance rover's descent stage was recently stacked atop the rover at Kennedy Space Center, and the two were placed in the back shell that will help protect them on their journey to Mars. In this image, taken on April 29, 2020, the underside of the rover is visible, along with the Ingenuity helicopter attached (lower center of the image). The outer ring is the base of the back shell, while the bell-shaped objects covered in red material are covers for engine nozzles on the descent stage. The wheels are covered in a protective material that will be removed before launch. Image Credit: NASA/JPL-Caltech

70 days from now, the next launch window to Mars opens. That’s when NASA will launch their Perseverance Rover. New images from NASA show the advanced rover being put into the fairing, readying it for its long journey.
