NASA and the Private Sector - Page 195

The US Defense Department's ambitions beyond Earth just grew a little clearer. SpaceNews has learned the department recently put out a call for privately-made nuclear propulsion systems that could power small- and mid-sized spacecraft. The DoD wants to launch missions venturing beyond Earth orbit, and existing electric and solar spacecraft are neither suitable for that job nor suitable to smaller vehicles, the department's Defense Innovation Unit said.

The nuclear propulsion system will ideally offer "high delta-V" (above 33ft/s) while scaling down to less than 2,000kg in dry mass (4,409lbs on Earth). On top of providing electricity for the payload, the technology will hopefully keep the spacecraft warm when in shadow and minimize radiation both on the ground and to other components. Responses are expected by September 23rd, with contracts handed out as quickly as 60 to 90 days afterward.

Officials acknowledged they were making the request as a matter of expediency. NASA and other agencies are already developing or backing nuclear spacecraft, but those won't be ready for a long while. The DoD is hoping for a prototype within three to five years — this technology would serve as a stopgap that puts nuclear propulsion into service relatively quickly for near-term projects.

While the request didn't provide clues as to what spacecraft were in the works, the focus on smaller spacecraft suggests it could involve probes, satellites or other vehicles with modest goals. You won't see this power human trips to Mars. All the same, it's clear the DoD is frustrated by the limitations of existing spacecraft engines and wants a fast track to more powerful designs.

Steve Wozniak has started a company called Privateer Space. The Apple co-founder announced the private space firm on late Sunday. Unfortunately, other than to promise his company would be “unlike the others,” Woz didn’t provide many details on the venture.


A teaser Privateer released on YouTube mentions the startup was co-founded by former Apple engineer Alex Fielding. Wozniak and Fielding have collaborated frequently over the years. Back in 2002, they co-founded a company called Wheels of Zeus (WoZ), which worked on GPS smart tags. Wozniak later sat on the board of directors of Ripcord Networks, the robotics startup Fielding founded after Wheel of Zeus shut down in 2006.


On its website, Privateer says it will have more to share at the upcoming AMOS tech conference in Maui, Hawaii that’s scheduled to start on September 14th. What's clear is Woz and company are about to enter a highly competitive market that is dominated by billionaires like Elon Musk and Jeff Bezos. That's not an easy space to succeed in.
