Rocket Lab ‘punched through the wall,’ CEO says, passing key milestone in effort to reuse rockets

Rocket Lab launched seven spacecraft early Friday as the builder of small rockets completed its main task, but the mission also came with a significant additional achievement.

After launching from New Zealand, the company successfully returned the Electron rocket’s booster — the lower portion and most expensive part of the rocket — through Earth’s atmosphere. By navigating the booster through reentry, Rocket Lab is one step closer to becoming one of the few in the world able to recover a rocket booster.

It’s a critical development in Rocket Lab’s plan to catch the booster with a helicopter in midair and reuse it for future missions. Additionally, if successful, Rocket Lab would join SpaceX as the only private company to return an orbital-class rocket booster.

Rocket Lab CEO Peter Beck broke down the results of the test in a call with CNBC on Friday, explaining how the company got the booster through the atmosphere’s dense “wall” during reentry.

“The real challenge in this program has been ‘can we get through the wall’ and today we punched through the wall and came out the other side in great shape,” Beck said. “We knew that we had a chance of getting it through the wall and all the way down to the water but with anything reentry it’s hugely difficult to model.”

Beck’s company, much like Elon Musk’s SpaceX, wants to recover the boosters so it can launch more often while simultaneously decreasing the material cost of each mission. But Rocket Lab’s approach to recovering its boosters is notably different than SpaceX’s, which uses the boosters’ engines to slow it down during reentry and add wide legs to land on large concrete pads.

Rocket Lab, instead, is testing a technology Beck calls an “aero thermal decelerator” — essentially using the atmosphere to slow down the rocket. After separating from the upper stage of the Electron rocket, which carried the spacecraft into orbit, Rocket Lab’s onboard computer guided the booster through reentry, successfully flipping it around 180 degrees.

The booster of Rocket Lab’s Electron rocket separates as its upper stage, with its engine nozzle visible in the foreground, continues on to orbit.

“We maintained control of the stage and guided it through the narrow corridor with the heat shield and the right orientation, the right angle of attack,” Beck said. “And, not only we were able to hold telemetry on it all the way to impact at sea, we had tremendous amount of instrumentation on board that said the stage was very healthy when it impacted the ocean.”

The booster remained stable through the intense reentry, slowing to a speed of less than 560 miles per hour.

“We had absolutely no decelerators on board; this was coming in as hot as it could ever come in,” Beck said.

The booster then smashed into the ocean and disintegrated, a move that Rocket Lab planned if the reentry process was successful.

“We had the team in an aircraft out in the middle of the Pacific Ocean circling with a whole lot of telemetry on board,” Beck said. “The team’s pouring over the data now to see what was in a good shape and what wasn’t but the preliminary results show the stage was remarkably healthy.”

Next up for Rocket Lab’s recovery attempts will be adding parachutes, which will deploy once the booster reenters the atmosphere. The company then plans to use a helicopter to snag the parachute in midair, to carry the booster back to a soft landing on a Rocket Lab boat.

“What we can say categorically from today’s flight is that reusability for Electron is viable and we’re pretty confident it’s going to happen,” Beck said.

Rocket Lab is the leading private company that builds small rockets — its Electron is about a fifth the size of a SpaceX Falcon 9 rocket. The company specializes in launching batches of small spacecraft, which are often about the size of a microwave oven.

Including the seven satellites from customers Alba Orbital and ALE on this 10th mission, Rocket Lab has successfully put 47 small satellites into orbit.

A launch on Electron goes for about $6.5 million to $7 million per rocket. The company has its headquarters in California, with launch facilities in New Zealand and Virginia. It produces one Electron rocket about every 20 days, with launches nearly once a month. But Rocket Lab is looking to accelerate production, aiming to produce a rocket every other week by the end of 2020.

The company is aiming to launch its 11th mission in the first weeks of next year. 

“The next flight is a repeat of this flight … it did such a great job on the first one that we’ll fly the second exactly the same and gather more data,” Beck said. “We’ll try and get a parachute and decelerator on this thing as soon as we can.”

Rocket Lab’s webcast of Friday’s flight showed some live video from the booster just before it began reentry. While Beck explained the company turned that camera off for this test to get as much data as possible, Rocket Lab will probably show more footage on the next flight.

“Now that we have a lot more confidence in the data, we’ll probably hold on to the videotapes a bit longer,” Beck said.
