Quickly, when it enters a brand new section, U.S. House Methods Command’s House Safari Program Workplace—in addition to satellite tv for pc builder Millennium House Methods and launch supplier Firefly Aerospace—might get a name at any second from the U.S. House Power and be instructed to launch the Victus Nox satellite tv for pc into low Earth orbit.
“We don’t know—I don’t even know [and] my management doesn’t even know right now when we’re going to be requested to launch,” says Lt. Col. MacKenzie Birchenough, House Safari’s materiel chief. “They should be prepared anytime over the subsequent six months.”
The Pentagon needs extra tactically responsive house capabilities
On-orbit spare satellites are a doable resiliency technique
Millennium House is wrapping up the construct section of the Victus Nox spacecraft, shifting this system towards a six-month sizzling standby section. Throughout this era, as soon as given the “go” command, the House Safari Program Workplace—arrange in 2021 as a “high-speed integrator for specialised house missions”—would have 60 hr. to gas, load up after which transport Victus Nox, an area area consciousness satellite tv for pc, from Millennium House’s El Segundo, California, manufacturing unit to Vandenberg SFB, a journey of about 140 mi. by plane. After arriving on the base, the group could be placed on a 24-hr. standby for launch.
The “tactically responsive house” mission is designed to show a reputable response to new, threatening spacecraft from an adversary. It sometimes takes years to develop a satellite tv for pc and months to arrange for a launch, however the timeline for Victus Nox has been minimize to a little bit over a yr.
“We’re undoubtedly shrinking issues very drastically,” Birchenough says. The brief schedule is an try to be “completely as life like as doable,” she says. “We don’t know what threats we is likely to be dealing with within the coming years. We have to have the power to reply rapidly.”
House Safari declines to call particular threats, however some Chinese language and Russian spacecraft appear to be able to maneuvering near U.S. navy satellites for spying and even to trigger injury utilizing a grappling arm. In recent times, house area consciousness has turn into a precedence for the House Power because it seeks to grasp what adversaries are doing with their spacecraft in areas of house starting from low Earth orbit all the best way to lunar orbits.
Victus Nox, Latin for “conquer the evening,” will probably be for demonstration functions solely, and the spacecraft won’t be used to look at any particular risk, Birchenough says. House Safari declines to speak in regards to the functionality of the small satellite tv for pc.
For the demonstration, Millennium—a Boeing subsidiary—pulled a satellite tv for pc bus from its manufacturing line, modified it and delivered it about eight months after it was awarded this system. The corporate declines to say which satellite tv for pc bus was used. The Victus Nox satellite tv for pc, which lately accomplished environmental testing, was in regards to the dimension of a minifridge when considered by Aviation Week throughout a tour of the corporate’s amenities.
Millennium House is “80% vertically built-in”—it manufactures 22 in-house merchandise—and that helps it quickly assemble novel satellites, says Andrew Chau, Millennium House’s superior tasks program supervisor for the Victus Nox spacecraft.
“In fact, one in all our huge challenges right here is with the ability to help these fast timelines,” he says. “We have now the benefit at Millennium of getting an lively manufacturing line. By doing so, we had been in a position to leapfrog quite a lot of these lengthy procurement timelines.”
Retaining all personnel vigilant through the six-month sizzling standby section shouldn’t be life like, so House Safari, Millennium House and launcher Firefly Aerospace have created fallbacks.
“All of us must guarantee that now we have redundancy in our group, as a result of we don’t know when that decision goes to return in,” Birchenough says. “There will probably be holidays, household occasions, sicknesses and issues that occur over the subsequent six months that now we have to be ready for.”
The Victus Nox group is trying to work out a number of the kinks quickly with a dry run utilizing a mockup of the house area consciousness satellite tv for pc. When the actual name to launch comes, the group will ferry the satellite tv for pc to Vandenberg in a Boeing C-17 transport.
“We’re additionally reserving the choice to guarantee that we are able to drive it safely to Vandenberg on a brief timeline,” Birchenough says. “Los Angeles visitors may pose points with that.”
As soon as at Vandenberg, the group could be put again on standby. “We [will] look forward to notification to launch,” Birchenough says. “As soon as that notification to launch comes, the group has 24 hr. to be able to launch.”
The satellite tv for pc is slated to be lofted by a Firefly Aerospace launch car. In October, that firm’s Alpha small-satellite booster reached orbit for the primary time after launching from Vandenberg. The 2-stage Alpha launch system has a raise capability of two,580 lb. to low Earth orbit.
Millennium delivered Victus Nox about eight months after contract award.

Birchenough notes that the satellite tv for pc could not take off precisely inside 24 hr.—as it might be delayed attributable to climate or orbital mechanics—“however the group will completely be able to go.”
As soon as Victus Nox is on orbit, the group will probably be tasked with making it mission-capable inside 48 hr. “It doesn’t do us a lot good to get one thing on orbit rapidly if we are able to’t use it very quick as nicely,” Birchenough notes.
Victus Nox is a follow-on demonstration to the House Power’s Tactically Responsive Launch-2, a 2021 mission that put a expertise demonstration satellite tv for pc on orbit inside 21 days of being requested. The demonstration used a Northrop Grumman Pegasus XL rocket, carried aloft to 40,000 ft. beneath the centerline of the corporate’s “Stargazer” L-1011 plane, a modified Lockheed L-1011 TriStar airliner, dropped after which launched into house.
Along with having a shared curiosity in tactically responsive house launches, Northrop Grumman and Firefly Aerospace in August introduced a partnership to develop a first-stage improve for the Antares rocket and a brand new medium-launch car.
Birchenough says quite a lot of classes had been discovered from Tactically Responsive Launch-2. “One of many huge takeaways was that it’s rather more than simply about launch,” she says, noting a must concentrate on fast house car improvement in addition to rapidly acquiring launch vary and regulatory approval. “Making an attempt to ensure we get all these approvals in a brief timeline could be difficult,” she says.
House Safari sees 3 ways to satisfy the House Power’s tactical responsive house wants. Along with launching quickly from the bottom, this system workplace is contemplating methods to maintain spare satellites on orbit.
“If the asset was already on orbit, we might transfer it on the time of want—or successfully flip it on on the time of want—with out having to undergo the launch section,” Birchenough says. House tugs may very well be used to reposition spare spacecraft quickly, she provides.
The House Power additionally may buy information from business spacecraft operators, Birchenough says. “The final word aim right here is to get to a permanent, tactically responsive functionality within the [2025-26] timeframe,” she says.
Whereas a lot emphasis has been positioned on small launch automobiles and the kind’s capability to insert small spacecraft into particular orbits rapidly, House Safari is also contemplating methods for spacecraft to squeeze on the final minute onto rideshare launches, resembling SpaceX’s Transporter missions, Birchenough says.
For its half, Millennium House is aiming to have the ability to launch its satellites on any rocket accessible, CEO Jason Kim says. “We attempt to have actually good relationships with all of the launch suppliers as a result of we need to be launch-vehicle-agnostic,” he says.
Previous to trying these further tactically responsive house missions, House Safari needs to wring out the Victus Nox demonstration to see what could be discovered. Birchenough says the toughest half to this point has been attempting to determine methods to squeeze in a lot into such a brief schedule. “We’re actually stressing the system,” she says.
