Science fiction space movies can do a poor job of educating people about space. In the movies, hot-shot pilots direct their dueling space ships through space as if they’re flying through an atmosphere. They bank and turn and perform loops and rolls, maybe throw in a quick Immelman, as if they’re subject to Earth’s gravity. Is that realistic?
In reality, a space battle is likely to look much different. With an increasing presence in space, and the potential for future conflict, is it time to think about what an actual space battle would look like?

Like all other technologies, satellite technology has grown in leaps and bounds in the past couple decades. Satellites can monitor Earth in increasingly high resolutions, aiding everything from storm forecasting, to climate change monitoring, to predicting crop harvests. But there’s one thing still holding satellites back: altitude.

NASA’s X-Plane Program has been around for 70 years. Over the course of those decades, the agency has developed a series of airplanes and rockets to test out various technologies and design advances. Now NASA has cleared the newest one, the X-59, for final assembly.

The X-37B, the US Air Force’s experimental, Orbital Test Vehicle (OTV) has come back down to Earth after 780 days. It landed at the Kennedy Space Center Shuttle Landing Facility on Oct. 27, 2019, at 3:51 a.m. after breaking its own record for time in space. The X-37B has now spent 2,865 total days in orbit.
The question is, what’s it doing up there?

Currently, commercial air travel accounts for 4 to 9% of the anthropogenic greenhouse gases that contribute to climate change. What’s worse, airplane emissions are on the rise thanks to rising populations and the increasingly globalized nature of our economy. Hence why NASA has been pursuing the development of electric aircraft these past few decades.
Much like reusable spacecraft and infrastructure, electric aircraft are part of NASA’s pursuit to make aerospace cheaper, more efficient and less harmful to the environment. Their efforts bore fruit in the form of the X-57 Maxwell – the first all-electric experimental aircraft – which was recently delivered to the NASA Armstrong Flight Research Center (AFRC) in Edwards, California.

To the scientifically uninitiated, it might seem like a frivolous idea: That those slight, wispy clouds that trail behind jet aircraft at such high altitudes could contribute to climate change. But they do.
Scientists love to measure things, and when they measured these contrails, which is short for condensation trails, they found bad news. Though they look kind of beautiful and ephemeral on a summer day, they pack an oversize punch when it comes to their warming effect.

A dramatic week in space launcher politics has left NASA’s Space Launch System (SLS) with a vastly reduced launch manifesto and casts doubt on the prospects of future upgrades to the massive launch vehicle.
On Monday the White House’s budget request laid out the administration’s plans for NASA’s coming years. For SLS there were three significant changes.

When it comes to the future of space exploration, the name of the game is “save money”. To do this, space agencies and aerospace companies around the world are investing in things like reusable rockets, single-stage-to-orbit (SSTO) rockets, and reusable space planes. This last concept builds on the tradition established by the Space Shuttle and Buran spacecraft, two reusable vehicles designed to make space launches more affordable.
The one drawback of these spacecraft was the fact that it still took two rocket boosters and a huge external fuel tank to put them into orbit. This is where the Synergetic Air Breathing Rocket Engine (SABRE) comes into play. With the help of the European Space Agency (ESA) and the UK Space Agency (UKSA), this revolutionary hypersonic engine recently took a big step towards fruition.

After more than 10 years of hard work, NASA has reached another milestone. We’re accustomed to NASA reaching milestones, but this one’s a little different. This one’s all about a type of photography that captures images of the flow of fluids.

Elon Musk indicates that the SpaceX Starhopper has been damaged after being toppled in 50 mile-per-hour winds. This will take a few weeks to repair.
