NASA Selects Maxar to Build Lunar Gateway Power & Propulsion Element

WASHINGTON (NASA PR) — In one of the first steps of the agency’s Artemis lunar exploration plans, NASA announced on Thursday the selection of Maxar Technologies, formerly SSL, in Westminster, Colorado, to develop and demonstrate power, propulsion and communications capabilities for NASA’s lunar Gateway.

“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. “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 power and propulsion element is a high-power, 50-kilowatt solar electric propulsion spacecraft – three times more powerful than current capabilities. 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.

This firm-fixed price award includes an indefinite-delivery/indefinite-quantity portion and carries a maximum total value of $375 million. The contract begins with a 12-month base period of performance and is followed by a 26-month option, a 14-month option and two 12-month options.

Spacecraft design will be completed during the base period, after which the exercise of options will provide for the development, launch, and in-space flight demonstration. The flight demonstration will last as long as one year, during which the spacecraft will be fully owned and operated by Maxar. Following a successful demonstration, NASA will have the option to acquire the spacecraft for use as the first element of the Gateway. NASA is targeting launch of the power and propulsion element on a commercial rocket in late 2022.

“We’re excited to demonstrate our newest technology on the power and propulsion element. Solar electric propulsion is extremely efficient, making it perfect for the Gateway,” said Mike Barrett, power and propulsion element project manager at NASA’s Glenn Research Center in Cleveland. “This system requires much less propellant than traditional chemical systems, which will allow the Gateway to move more mass around the Moon, like a human landing system and large modules for living and working in orbit.”

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.

    Good call, congrats to SSL folks

    This one will be delivered on time

  • duheagle

    Given the current slump in GEOsat orders, it will likely be delivered ahead of schedule. I’m sure Maxar/SSL would like to be even further into NASA’s good graces than they already are. I’m thinking they might be looking at bucking LockMart for some of that big-ticket planetary science work NASA hands out.

  • savuporo

    I’m still curious to know whatever happened to the “commercial” Mars telecom orbiter bids, that NASA shelled out over 50M for. SSL, Lockheed and all the other comsat builders bid, and then NASA quietly shut it down

  • therealdmt

    Nice to see this finally get going. I’ve been hearing about this PPE thing since Obama’s Asteroid Redirect. Anyway, looking forward to hearing about it progressing going forward

  • duheagle

    I’m also curious. Perhaps it was something as simple as NASA deciding that if it put money into upgrading Mars-adjacent infrastructure then influential people might expect the agency to actually gin up some kind of realistic Mars effort involving people.

  • Aerospike

    Wasn’t NASA supposed to give out 2 contracts for the PPE demonstration and then select one that met all the criteria during the checkout phase?

    When did that plan got shelved? And isn’t relying on a single provider going to increase the risk?

  • duheagle

    Given the speed-up occasioned by the advent of the Artemis project, maybe NASA just went to all the likely suspects and asked for an earliest availability date and a fixed price, did a bit of due diligence, then took the contract to the entity with the best answer to those questions and got it signed.
