Astra engineers identified two problems — an electrical design issue and a software glitch — that prevented a rocket from reaching orbit last month with a suite of NASA-sponsored CubeSats, clearing the way for a return-to-flight mission that could launch from Alaska as soon as Monday.
The private spaceflight startup Astra will launch a commercial mission for Spaceflight, Inc. today and you can watch it live online.
SpaceX has launched about 150 missions in its first 20 years. Here's a look at 20 of the most important and memorable of them.
Reusing rockets and dreaming big are some of the things that have made SpaceX stand out.
Asteroid samples collected during the Hayabusa mission have helped scientists better model potential impacts of near-Earth objects.
An Earthbound experiment is replicating the extreme heat found in galaxy clusters located in deep space using nearly 200 lasers.
Sometimes in space, even when you’re millions of kilometers from anything, you’re still being watched. Or at least that’s the case for the Parker Solar Probe, which completed the 11th perihelion of its 24 perihelion journey on February 25th. While the probe was speeding past the Sun, it was being watched by over 40 space and ground-based telescopes.
This will likely come as a surprise to no one who has closely watched the development of NASA’s next giant rocket, the Space Launch System (SLS), but it’s going to be expensive to use. Like, really expensive – to the tune of $4.1 billion per launch, according to the NASA Inspector General. That’s over double the original expected launch cost.
The first teaser trailer for the next live-action "Star Trek" spinoff, "Star Trek: Strange New Worlds," has beamed in from Paramount Plus.
You can watch a big asteroid make a safe flyby of Earth today (March 11) from any spot with good internet access.
The planets in our solar system come in two forms: Some are rocky, and some are gaseous. But all of the moons in our solar system are rocky, even the ones that orbit gas giants. So why aren't some moons in the solar system made of gas? And are there gaseous moons anywhere in the universe?
Some companies make money out of 'selling stars', or rather selling opportunities to name them, perhaps as a gift to a loved one. But is it really worth the money?
A new image from the European Southern Observatory (ESO) captures a stunning view of the Cartwheel galaxy following a recent stellar explosion.
Albert Einstein saw beyond human tribalism to an enlightened realm of tolerance. We can too: He left us clear directions for how to do it.
Are we alone in the Universe? Could there be countless sentient life forms out there just waiting to be found? Will we meet them someday and be able to exchange knowledge? Will we even recognize them as intelligent life forms if and when we see them? Or worse, will they recognize us as intelligent life? When it comes to astrobiology, the search for life in the Universe, we don’t know what to expect. Hence, the speculation and theoretical studies into these questions are so rich and varied!
For millennia, humans have gazed at the northern lights with wonder, pondering their nature and source. Even today, these once mysterious phenomena still evoke awe, though we understand them a little better now. Still, most of our knowledge about the northern lights has come recently, in the last century or two. Astronomers and meteorologists of the 1800s worked for years to understand the aurora, wondering if they were a feature of Earth’s atmospheric weather, of outer space, or, perhaps, something that straddled the boundary in-between. This centuries-old attempt to understand the northern lights was an immense, international-scale project, and, through fortunate happenstance, it even helped inspire one of the underlying foundations of modern society – time zones.
