Rocket Lab challenges NASA's $700 million Mars contract award to Blue Origin

Rocket Lab has formally challenged NASA’s decision to award a $700 million Mars communications contract to Jeff Bezos’s Blue Origin, dragging the US space agency’s plans for the Red Planet into a legal standstill.

The Long Beach-based launch provider filed a bid protest with the US Government Accountability Office (GAO) on 11 September, claiming the procurement process was unfair, flawed, and violated eligibility rules set by Congress.

The dispute centres on the Mars Telecommunications Network, a project to build and operate a spacecraft that will act as a vital data link between Earth and Mars. NASA relies on aging scientific probes, such as the 2001 Mars Odyssey and 2005 Mars Reconnaissance Orbiter, to relay signals from its surface rovers. The new spacecraft is meant to replace them, with a scheduled launch by the end of 2028 and operations starting in 2030.

The core of the dispute

In a statement on social media platform X, Rocket Lab claimed that NASA’s evaluation was "punitive" and riddled with "incorrect assertions and conclusions" regarding its technical bid.

The company also argued that the decision violated specific criteria set out by US lawmakers. When Congress approved $700 million for the project in July 2025, it specified that eligible bidders must be US commercial companies that received NASA funding in fiscal year 2024 or 2025 for Mars Sample Return studies, and who proposed a separate, independently launched orbiter.

Rocket Lab, which bid an orbiter based on its established Explorer platform, claims it was the only bidder that met the requirements with a standalone spacecraft. While Blue Origin also received Mars study funding, NASA has not published the full proposals, leaving it unclear how the agency assessed the competitors against the congressional rules.

Blue Origin warns of delays

By law, Rocket Lab's protest triggers an automatic stay on the contract, forcing Blue Origin to pause its work while the GAO reviews the case. The watchdog has 100 days to issue a ruling, giving it until mid-December 2026 to decide whether NASA must re-evaluate the bids.

Blue Origin has warned that the legal challenge could jeopardise the entire project. Because missions to Mars can only launch during specific planetary windows every 26 months, the company said any pause risks missing the target.

"We remain confident in the strength of our proposal," Blue Origin said in a statement. "With limited Mars launch windows, any delay will greatly risk the timely deployment of this critical communications capability."

Investor nerves

The legal battle comes at a busy and sensitive time for Rocket Lab. While the company’s small Electron rocket is flying regularly—averaging more than one launch a month—its stock has slid roughly 22 percent over the past month.

Investors are waiting on several moving parts. Rocket Lab is currently trying to close an $8 billion acquisition of satellite operator Iridium, with a shareholder vote scheduled for 24 September. At the same time, its larger Neutron rocket, designed to compete with SpaceX and Blue Origin for heavy payloads, is slated to arrive at the launch pad before the end of the year, though a maiden flight date has not been set.

For Rocket Lab, challenging NASA is a high-stakes gamble. Winning the protest could secure a flagship deep-space mission; losing it could signal to the market that the company is still playing catch-up with its multi-billionaire-backed rivals.
