Reusable rocket engines have become all the rage lately, even as NASA's continually delayed Artemis I mission attempts to launch with non-reusable technology. Realistically, the only way to significantly lower launch costs is to reuse the engines rather than build them from scratch every time. Another small start-up company, RocketLab, has successfully retested a rocket that has flown in space.

SpaceX famously has flown several of its Raptor engines into space multiple times already, making headlines along the way. But it's not the only company with ambitions for reusing its rockets. RocketLab, which makes a much smaller rocket called the Electron, has also been eyeing this milestone for a while now.

The company made headlines back in May when it made a spectacular show of catching its rocket stage out of the air with a helicopter.

While hundreds of thousands of people made their way to the Space Coast two weekends in a row for a shot to see the most powerful rocket to ever lift off from Earth, a couple of scrubs for NASA's Artemis I mission left them disappointed.

But for those who were making a weekend out of their efforts, there was at least one rocket that lit up the sky for those who hung around.

SpaceX has continued its frenetic pace of Falcon 9 launches including a couple of Starlink missions that took flight: one right before midnight last weekend on Aug. 27, about 32 hours before NASA called off its first Artemis I attempt; and then again Sunday night about 32 hours after NASA was aiming for its second try to send up its Space Launch System rocket with the Orion capsule to the moon.

So while NASA may eventually have to roll back the Artemis I hardware capable of 8.8 million pounds of thrust on liftoff to the Vehicle Assembly Building, SpaceX keeps sending up its 1.7 million pounds of thrust servings.

NASA has revamped its "Eyes on the Solar System" 3D visualization tool, making interplanetary travel easier and more interactive than ever. More than two years in the making, the update delivers better controls, improved navigation, and a host of new opportunities to learn about our incredible corner of the cosmos—no spacesuit required. All you need is a device with an internet connection.

Trace the course Artemis I will take to lunar orbit, or touch down with Perseverance during its harrowing entry, descent, and landing on the Red Planet. Learn the basics about dwarf planets or the finer points of gas giants, and ride alongside no fewer than 126 space missions past and present. You can even follow the paths of spacecraft and celestial bodies as far back as 1949 and as far into the future as 2049.
