SpaceX’s upgraded rocket makes debut

Falcon 9 soars as first stage makes perfect landing

SpaceX’s upgraded Falcon 9 rocket made its debut Friday afternoon, and the rocket’s first-stage stuck the landing after a previous launch attempt ended in a scrub.

The Hawthorne, Calif., space company launched Bangladesh’s first geostation­ary communicat­ions satellite Friday at 4:14 p.m. Eastern time from Kennedy Space Center in Florida. SpaceX intended to launch the satellite Thursday on its newly upgraded Block 5 Falcon 9, but the rocket’s computers initiated an abort with 58 seconds left in the countdown.

About eight minutes after liftoff, the first-stage booster returned to Earth, landing on a floating sea platform. It was SpaceX’s 25th booster landing. The satellite deployed about 33 minutes after liftoff.

The changes incorporat­ed into the Block 5 version of the rocket are intended to allow at least 10 reuses of the first-stage booster and improve performanc­e and turnaround time between launches. Reusabilit­y is key to SpaceX’s plan to reduce launch costs, and eventually, make its way to Mars.

Some of those changes include upgraded electronic­s and guidance systems, as well as new thermal protection technology to safeguard against fires in the engine and on the booster’s landing legs, SpaceX Chief Executive Elon Musk said in a Thursday call with reporters.

“This is a ridiculous­ly hard thing,” Musk said. “It has taken us … 16 years of extreme effort and many, many iterations and thousands of small but important developmen­t changes to get to where we think this is even possible. Crazy hard. We still need to demonstrat­e it. It's not like we've done it. But it can be done.”

Block 5 will be the final substantia­l update to the workhorse Falcon 9. That rocket and the heavy-lift Falcon Heavy will eventually be replaced by SpaceX’s next-generation BFR rocket and spaceship system, which will be built at the Port of Los Angeles.

The latest version of the Falcon 9 will also be used to carry astronauts to the Internatio­nal Space Station and to hoist national security satellites into space, meaning input from NASA and the U.S. military factored heavily into its design and developmen­t.
