On Tuesday, SpaceX pulled off its biggest achievement yet, launching and landing its much-anticipated monster rocket Falcon Heavy. But one of the most undeniably cool moments of the mission was definitely watching the big rocket’s boosters return to Earth.

There were plenty of emotional highlights for the Falcon Heavy launch, from the initial realization this goliath was actually going to blast off successfully to the moment that David Bowie’s “Life on Mars” began to play as Elon Musk’s Tesla Roadster began its infinite voyage to the red planet. Nothing though was quite as straight-up awesome as the shot of both the side boosters landing simultaneously on SpaceX’s ground pad in Cape Canaveral.

It was a textbook landing for the two boosters, which came down on Landing Pads One and Two nearly simultaneously. But then this would be old hat for both of them, as they were each recovered and reused from previous Falcon 9 missions. One had landed on the ground pad before, while the other had landed on one of the floating droneships that provide a landing spot in the middle of the ocean.

Speaking of which, it is less clear as of this writing what exactly happened with the central core booster. The plan was for it to land on the Atlantic Ocean droneship Of Course I Still Love You, though this is all the webcast revealed about its fate.

The Falcon Heavy rocket comprises three Falcon 9 rockets. The central core is specially strengthened and contains both the first and second stages, while the side boosters are just the first stages of the additional Falcon 9 rockets. SpaceX sought to land all three, though the greater distance traveled and greater stress endured by the core booster meant it was always going to be the least likely to recover.

Whatever the ultimate fate of core booster, the successful landing of the side boosters makes for one incredible visual, and an impressive proof of concept for the idea that Falcon Heavy — a rocket powerful enough to take humans back to the moon — can be sufficiently reusable to make SpaceX’s vision of low-cost, repeatable spaceflight that much more a reality.

Apple’s next iPhone models are almost here, which raises an annual dilemma for consumers thinking about getting a new phone: hold on to what you got until the new slate of phones is released — likely next month — or hunt around for deals on last year’s models?

As the tech world turns its attention to the next range of devices, evidence suggests buyers could grab a discount on used models ahead of the announcement while those in the market for a new phone are likely better off waiting until after the new phones launch to take better advantage of the product cycle.

Google celebrated the life of Mary G. Ross on Thursday, with a commemorative doodle on what would have been the pioneer aerospace scientist’s 110th birthday. Ross, a Native American female engineer, helped develop some of the first concepts for flyby missions past Venus and Mars, paving the way for humans to explore the stars and visit other planets. Ross proudly described some of her most important moments this way: “I was the pencil pusher, doing a lot of research. My state of the art tools were a slide rule and a Frieden computer.”

SpaceX took a big step toward its goal to reuse rockets in record time, after it successfully launched a Falcon 9 Block 5 rocket with a Merah Putih satellite on Tuesday. The first stage rocket was first used in May, and it marks the first time that the more reusable “Block 5” design has reflown after a previous mission. It’s a key step toward CEO Elon Musk’s ultimate goal to refly rockets in just 24 hours.

Mars is kind of a bummer: That place is a hotbed of dynamic dust storms that got so big in recent months that they encircled the entire planet. Those conditions, sure to be a challenge for future Mars colonies, are a buzzkill for NASA’s Opportunity Rover right now: A dust storm forced the droid, which has been roaming Mars for 14 years, to shut down in June, and it’s still turned off today.

SpaceX has brought a Dragon capsule back to Earth, after successfully completing a second month-long stint at the International Space Station. The company shared an image Sunday of the craft after its return to terra firma, two days after its departure from the space station, before its planned handover to NASA to retrieve the cargo inside.
