Space Force is Starting to Train its Soldiers to Fight… in Space?

Shane Clark, WGS-10 Mission Director and Senior Materiel Leader from the Launch Enterprise Systems Directorate, runs through the countdown checklist, during a MDR (Mission Dress Rehearsal) Tuesday afternoon Mar. 11, 2019 inside the Delta Operations Center at Cape Canaveral Air Force Station, along Florida's Space Coast.

On February 19th, 2019, the US Space Force (USSF) was officially created with the signing of Space Policy Directive–4. This effectively broke off from the US Air Force Space Command (AFSC) and made into the sixth and youngest independent branch of the armed forces. Since then, the USSF has established a headquarters, taken on staff from the US Air Force, and even produced a recruitment video!

In their latest announcement, the US Space Force stated that it will begin training soon to develop their staff’s “space warfighting skills.” This will include training personnel to specialize in orbital warfare, electronic warfare, military strategy, and others. The immediate aim is to produce personnel who can control US space infrastructure and protect it from physical, electronic, or digital attacks.

NASA is Giving the SLS a “Green Run” to Prepare it for Launch in Late 2021

With the passage of the NASA Authorization Act of 2010, work began on a launch vehicle that would carry cargo and crews back to the Moon and beyond. This vehicle is known as the Space Launch System (SLS), a heavy-launch system that (once fully operational) will be the most powerful rocket in the world since the Saturn V – the venerable vehicle that took the Apollo astronauts to the Moon.

Unfortunately, the development of the SLS has suffered from multiple delays over the past few years, causing no shortage of complications. However, engineering teams at NASA’s Stennis Space Center near St. Louis, Mississippi, recently completed a Green Run of the SLS’s Core Stage, which involved testing the rocket’s critical systems in preparation for its inaugural launch by November of 2021.

Venus Meets Mercury This Weekend in a Fine Dusk Conjunction

What’s that? You say you’ve never seen elusive Mercury for yourself? You won’t have an excuse after this weekend, when the innermost world meets brilliant Venus at dusk in what is known as a planetary conjunction, one of the best for 2020.

NASA Proposes the Artemis Accords. The New Rules for Lunar Exploration

As part of Project Artemis, which was announced in May of 2019, NASA will be sending the first woman and the next man to the Moon for the first time since the Apollo Era. To make this happen, NASA has partnered with the private aerospace industry to develop all the necessary systems. At the same time, NASA has entered into collaborative agreements with other space agencies to ensure that lunar exploration is open to all.

To formalize these agreements and ensure that all parties are committed to the same goals, NASA recently drafted a framework for cooperative lunar exploration and development. Known as the Artemis Accords, this series of bilateral agreements (which are grounded in the Outer Space Treaty of 1967) establish common principles for international partners who want to become part of humanity’s long-awaited return to the Moon.

Earth Life Probably Can’t Spread to Mars Today

These dark, narrow, 100 meter-long streaks called recurring slope lineae flowing downhill on Mars are inferred to have been formed by contemporary flowing water. However, a new study by planetary scientists indicates that these may actually be the result of dry flows. Credits: NASA/JPL/University of Arizona

It’s no secret that Mars once had abundant water flowing on its surface in the forms of rivers, lakes, and even an ocean. For this reason, scientists continue to wonder whether or not Mars might have had life in the past. Today, the surface is an extremely cold, dry place where even a single droplet of water would instantly freeze, boil, or evaporate. Unless, of course, the water had salt dissolved in it.

If these “briny” patches still exist on Mars, then it’s possible there are small pockets on the surface where microbes can still exist. This presents problems as far as issues of “planetary protection” are concerned. However, a new study led by the Lunar and Planetary Institute (LPI) has shown that if life from Earth were brought over by robotic or human explorers, it probably couldn’t survive in these brines.

China’s New Crew Capsule Just Landed, and so Did Parts of their New Rocket!

China’s next-generation crewed spacecraft, which will replace the venerable Shenzou spacecraft in the coming years, recently returned to Earth after spending almost three days in space. The purpose of this mission was to test the deep space capabilities of the spacecraft that will be sending Chinese astronauts (taikonauts) to orbit, to the Moon, and beyond in the coming years.

In addition, this mission also saw China’s new Long March 5B (CZ-5B) heavy-lift rocket launch a payload to space for the first time. This rocket is the latest installment in the Long March family and will be vital to the creation of the third and largest Chinese space station. These two milestones have brought China a step closer to becoming a full-fledged superpower in space.

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!)

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.

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!)

Lunar Gateway Could be Built With the Falcon Heavy

In March of 2019, NASA was directed by the White House to land human beings on the Moon within five years. Known as Project Artemis, this expedited timeline has led to a number of changes and shakeups at NASA, not the least of which has to do with the deprioritizing of certain elements. Nowhere is this more clear than with the Lunar Gateway, an orbital habitat that NASA will be deploying to cislunar space in the coming years.

Originally, the Gateway was a crucial part of the agency’s plan to create a program of “sustainable lunar exploration.” In March of this year, NASA announced that the Lunar Gateway is no longer a priority and that Artemis will rely on an integrated lunar lander instead. However, NASA still hopes to build the Gateway, and according to a recent interview with ArsTechnica, this could be done with the help of SpaceX and the Falcon Heavy.
