KENNEDY
SPACE CENTER, FL – NASA Administrator Jim
Bridenstine announced that Maxar
Technologies has been chosen to build the first element of the Artemis programs
Lunar Gateway
project – namely the Power and Propulsion Element or PPE – that will power the future lunar orbiting mini
station.
“The power and propulsion element is the foundation of Gateway and a fine example of how partnerships with U.S. companies can help expedite NASA’s return to the Moon with the first woman and next man by 2024,” said NASA Administrator Jim Bridenstine during a May 23 speech at the Florida Institute of Technology, Melbourne, FL.
“It will be the key component upon which we will build our lunar Gateway outpost, the cornerstone of NASA’s sustainable and reusable Artemis exploration architecture on and around the Moon.”

“It will be the key component upon which we will
build our lunar Gateway outpost, the cornerstone of NASA’s sustainable and
reusable Artemis exploration architecture on and around the Moon.”
The PPE will serve as a communications relay reusable command and service module where astronaut crew flying in NASA’s Orion deep space capsule can dock on their way to the lunar surface and back, Bridenstine said during remarks at NASA’s Kennedy Space Center on May 23, attended by Space UpClose.
Furthermore the PPE enables landings on all areas of the moon including the lunar south pole for Project Artemis whereas NASA’s Project Apollo was limited to more equatorial regions.
NASA’s firm-fixed price contract with Maxar, formerly SSL, in Westminster, Colorado, is valued at $375 million.

NASA can significantly cut cost by using commercial providers for both hardware and launch services.
“The power and propulsion element is a high-power, 50-kilowatt solar electric propulsion spacecraft – three times more powerful than current capabilities,” according to NASA.
“As a mobile command and service module, the Gateway provides a communications relay for human and robotic expeditions to the lunar surface, starting at the Moon’s South Pole.”

Thereafter NASA will have the option to acquire
the spacecraft for use as the first element of the Gateway.
NASA is also in the process of contracting for the second Gateway element – a small habitation and utilization module with multiple docking ports.
“Charged with returning to the Moon within five years, NASA’s lunar exploration plans are based on a two-phase approach: the first is focused on speed – landing on the Moon by 2024 – while the second will establish a sustained human presence on and around the Moon by 2028. We then will use what we learn on the Moon to prepare to send astronauts to Mars.”
