DARPA wants a robotic satellite mechanic launched by 2022

By:

The Defense Advanced Research Projects Agency is on track to announce a new commercial partner for its robotic servicing payload by the end of the year, with plans to have a spacecraft in orbit in 2022.

“I'm standing here with a smile on my face. The program is moving forward and things are looking good and we're very hopeful,” Joe Parrish, program manager for the Robotic Servicing of Geosynchronous Spacecraft program at DARPA, said at the 2019 Global Satellite Servicing Forum Oct. 1. “We're looking to launch RSGS in late 2022.”

RSGS is intended to deliver a GEO spacecraft with a payload consisting of two large 2 meter arms and a number of tools that will allow it to perform maintenance and other work on satellites in GEO. The spacecraft will perform four main functions in space: inspection, orbital adjustments, anomaly resolution and installation of self-contained payloads.

With a host of cameras onboard, RSGS will be able to inspect other satellites. This can help operators on the ground diagnose problems and inform in-orbit repairs. It can also use its arms to capture a satellite and move it, either to a new orbit or to dispose of it. DARPA envisions RSGS being able, again using its arms, to install new payloads on existing satellites, replacing legacy hardware and augmenting its mission for years to come. And, of course, RSGS will be available to traverse the GEO landscape to help satellites that fail to deploy correctly.

“If somebody launches up into GEO while we're up there and a solar array fails to deploy or a reflector or antenna fails to deploy, we can come galloping to the rescue,” said Perrish. “The benefit is not to demonstrate robot arms waving around in space. The benefit is to increase the resilience of our infrastructure in space.”

While DARPA is developing the payload with robotic arms, according to Parrish, DARPA needs a commercial partner to build the spacecraft that will house the payload and carry it around in orbit.

“We're looking for the partner to provide the spacecraft bus — so using a heritage GEO bus that may have had some tailoring for RSGS requirements, integrating the payload and the spacecraft bus together, procuring and launching that integrated spacecraft to GEO, and then providing mission control center for operations for a long period of time,” explained Parrish.

Parrish said that the full project would be turned over in due time to the commercial partner to operate RSGS for fun and profit.

But DARPA has hit some stumbling blocks in securing that commercial partner.

In 2017, Orbital ATK sued DARPA to stop it from developing what it saw as competition to its own satellite servicing space vehicle. While that effort failed, the company's efforts to develop its own satellite servicing program have continued. Orbital ATK was acquired by Northrop Grumman in 2018, and now the Northrop Grumman subsidiary SpaceLogistics is preparing to launch the first satellite life extension vehicle into space in the coming weeks.

Then, in January, Maxar Technologies' Space Systems Loral pulled out of an agreement with DARPA to build the spacecraft to host the RSGS payload as the company moved out of the GEO construction market.

DARPA has spent much of the last year working to find a new commercial partner. In May they hosted a Proposer's Day to discuss the program with potentially interested companies, and now Parrish says they expect to announce a partner toward the end of the year.

“2019 has been quite a year,” said Parrish. “We are still in source selection for a new commercial partner.”

Meanwhile, work on the payload itself is ongoing.

The first of two flight robotic manipulator arms is in final assembly and will be shipped to the Naval Research Lab in the next two weeks, where it will be integrated into the payload. The second arm lags the first by about two months, said Parrish, and is currently in assembly.

In 2020, all of the components of the payload will be sent to NRL for assembly into the actual payload.

    Will COVID-Stressed Countries Slow Their Arms Buys?

    State Department's political-military leader sees mixed signals from abroad. Marcus Weisgerber The coronavirus pandemic might prompt U.S. allies to restructure arms deals for American-made weapons, a top State Department official. But R. Clarke Cooper, assistant secretary of state for political-military affairs, said there is still an appetite for U.S. weapons overseas — especially F-16 fighter jets and Patriot missile batteries. “If we're looking at long-term modernization plans across the board, we're seeing what I would say is [a] steady state in that place,” Cooper said Wednesday during a virtual Defense Writers Group meeting. Since April, the State Department has approved more than four dozen foreign arms deals with a potential total value of more than $91 billion. But just because the sales were approved doesn't mean they'll come to fruition. In some cases, U.S. companies are competing against one another and/or overseas firms for contracts. “On big-ticket modernization, while some states...may have looked to re-frame or push right to a later date particular procurements, we've not seen dramatic changes in their planning,” he said. “What it may mean is how they sequence certain procurements.” Germany last month canceled a multibillion- dollar helicopter competition between Boeing and Lockheed Martin, calling the project too expensive. At the same time, Switzerland recently moved forward with a competition to replace its F/A-18 Hornets. But economic pressures could prompt some countries to adjust payments schedules, Cooper said. “Based on their national budgets, [countries] might seek some sort of dependable undertaking,” he said. “Some states might seek foreign military financing or grant assistance.” By the way, Cooper added, the economic downturns could result in more NATO allies meeting the alliance's goal of members spending 2 percent of their gross domestic product on defense. “Bizarrely, we may have some states where their numbers look like they've had an increase [in defense spending] because they've had a drop in GDP,” he said. https://www.defenseone.com/business/2020/10/will-covid-stressed-countries-slow-their-arms-buys/169642/

    The US Navy’s top acquisition priority stumbles out of the gate

    By: David B. Larter The U.S. Navy's $122.3 billion Columbia-class ballistic missile submarine program is off to an inauspicious start after faulty welding was discovered in several missile tubes destined for both the Columbia and Virginia-class programs, as well as the United Kingdom's follow-on SSBN program. In all, 12 missile tubes manufactured by BWXT, Inc., are being scrutinized for substandard welds. Seven of the 12 had been delivered to prime contractor General Dynamics Electric Boatand were in various stages of outfitting, and five were still under construction. The Navy and Electric Boat have launched an investigation, according to a statement from Naval Sea Systems Command spokesman Bill Couch. “All BWXT welding requiring volumetric inspection has been halted until the investigation is complete,” Couch said. The bad welds came to light after discrepancies were discovered with the equipment BWXT used to test the welds before shipping them to GDEB, according to a source familiar with the issue. The discovery of a significant quality control issue at the very outset of fabrication of Columbia injects uncertainty in a program that already has little room for delays. The issue is made even more troubling because it arises from a vendor with an excellent reputation, and raises questions about whether the Navy can deliver Columbia on time, something the Navy says is vital to ensuring continuous nuclear deterrent patrols as the Ohio class reaches the end of its service life.

  • BAE successfully tests ground-launched APKWS rockets for first time

    BAE successfully tests ground-launched APKWS rockets for first time

    By: Aaron Mehta WASHINGTON — BAE Systems has completed a successful ground-to-ground test of its Advanced Precision Kill Weapon System rocket for the first time, the company announced Monday. The test, conducted at the U.S. Army's Yuma Proving Ground in Arizona, involved “several successful shots” of the APKWS rockets out of a launcher, built specifically for ground vehicles by Arnold Defense, according to BAE. The weapon has traditionally been launched from rotary or fixed-wing aircraft. A ground-based APKWS, delivered via the Arnold Fletcher launcher, was first unveiled in 2018. “Demand is growing for ground-to-ground precision munitions that provide a safe standoff distance for small ground units,” Greg Procopio, director of precision guidance and sensing solutions at BAE Systems, said in a statement. “We're working closely with our customer and partners to deliver that capability.” The APKWS laser-guided rocket is used by the U.S. Army, Air Force, Navy and Marine Corps. The Navy holds the program of record. The rockets have also spread via foreign military sales to more than a dozen foreign nations. However, the U.S. Army decided to end procurement of the rockets as a result of its “night court” budget review. In its fiscal 2021 budget request, the service said it redirected $122 million in funding from the rockets toward higher priorities. Even before the Army's decision was official, BAE was working to increase the flexibility of APKWS as a low-cost, precision-strike option. Late last year, the Air Force successfully tested it for missile defense, and the ground-to-ground version would add to the military options for the weapon. The company delivered more than 35,000 APKWS units by the end of 2019 and expects to deliver 18,000 in 2020. https://www.defensenews.com/land/2020/06/01/bae-successfully-tests-ground-launched-apkws-rockets-for-first-time/
