The first multi-spacecraft science mission to launch to Mars is now on its way, and catching a ride on the twin probes are the first kiwis to fly to the red planet.

NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) mission lifted off on a 22-month trip to Mars on Thursday aboard a New Glenn rocket. Once there, the identical satellites will enter Martian orbit to study in real time how space weather affects the planet’s hybrid magnetosphere and how the interaction drove Mars to lose its once-dense atmosphere.

Led by the Space Sciences Laboratory at the University of California, Berkeley—the two spacecraft are named “Blue” and “Gold” after the school’s colors—the ESCAPADE probes are the first Mars-bound vehicles to be designed, built, and tested by Rocket Lab, the end-to-end space company headquartered in California but founded in New Zealand.

The rocket company founded a quarter-century ago by billionaire Jeff Bezos made history Thursday with the pinpoint landing of an 18-story-tall rocket on a floating platform in the Atlantic Ocean.

The on-target touchdown came nine minutes after the New Glenn rocket, built and operated by Bezos’ company Blue Origin, lifted off from Cape Canaveral Space Force Station, Florida, at 3:55 pm EST (20:55 UTC). The launch was delayed from Sunday, first due to poor weather at the launch site in Florida, then by a solar storm that sent hazardous radiation toward Earth earlier this week.

“We achieved full mission success today, and I am so proud of the team,” said Dave Limp, CEO of Blue Origin. “It turns out Never Tell Me The Odds (Blue Origin’s nickname for the first stage) had perfect odds—never before in history has a booster this large nailed the landing on the second try. This is just the beginning as we rapidly scale our flight cadence and continue delivering for our customers.”

CAPE CANAVERAL, Florida—The second flight of Blue Origin’s New Glenn rocket was postponed again Wednesday as a supercharged wave of magnetized plasma from the Sun enveloped the Earth, triggering colorful auroral displays and concerns over possible impacts to communications, navigation, and power grids.

Solar storms like the one this week can also affect satellite operations. That is the worry that caused NASA to hold off on launching a pair of science probes from Cape Canaveral Space Force Station, Florida, on Wednesday aboard Blue Origin’s New Glenn rocket.

In a statement, Blue Origin said NASA, its customer on the upcoming launch, decided to postpone the mission to send the agency’s two ESCAPADE spacecraft on a journey to Mars.
