BOTHELL, Wash (Tethers Unlimited) — Tethers Unlimited, Inc. (TUI) announced the delivery of the first mesh network inter-satellite crosslink solution for small satellites. TUI’s SWIFT-LINQ™ network is a software ‘app’ that runs on TUI’s SWIFT® flight-heritage software defined radios to connect satellite constellations, clusters, and formations together with a resilient, adaptable mesh network.
SWIFT-LINQ supports standard TCP/IP protocols to enable seamless, straightforward data transfer between satellites. Satellites connected via SWIFT-LINQ can share resources and data, empowering groups of low-cost small satellites to perform missions that traditionally would have required large, very expensive satellites.
GREENBELT, Md. (NASA PR) — NASA has awarded a $142 million contract to Maxar Technologies of Westminster, Colorado, to robotically assemble a communications antenna and manufacture a spacecraft beam in orbit. The technology demonstration is slated to take place on NASA’s Restore-L spacecraft, designed to service and refuel a satellite in low-Earth orbit.
BOTHELL, Wa. (Tethers Unlimited PR) – Tethers Unlimited, Inc. (TUI) announced that it has successfully demonstrated on-orbit operation of the Terminator Tape, an affordable, lightweight solution for removing space debris from on orbit.
CHANTILLY, Va (TriSept PR) – TriSept Corporation, a leading provider of launch integration and mission management services, has signed comprehensive launch service agreements with Millennium Space Systems and Rocket Lab to support a unique mission aimed at helping to solve the ever-increasing low-Earth orbital debris challenge.
As NASA is funding research into lighter and more capable thermal protection systems (TPSs) producing using additive manufacturing (3D printing) as it looks to land ever larger payloads on other worlds and return extraterrestrial soil samples to Earth.
The space agency recently selected four heat shield proposals from corporate-university partnerships for funding under its Small Business Technology Transfer (STTR) program. The phase 1 grants are worth up to $125,000 over 13 months.
During the 1970’s, David Bowie sang about Ziggy Stardust and the spiders from Mars. If Tethers Unlimited has its way, the Red Planet will be crawling with them.
Earlier this month, NASA selected the Bothell, Washington-based company for a small business award to work on its Sensing and Positioning in Deep Environments with Retrieval (SPIDER) surface exploration system.
NASA is continuing to encourage the use of 3-D manufacturing technologies for use on Earth and in space through the space agency’s Small Business Innovation Research (SBIR) program.
In addition to funding two projects by Made in Space focused on glass alloys and structures for advanced interferometery missions, the space agency also selected six other additive manufacturing proposals for funding under SBIR Phase II.
The awards, which are worth up to $750,000 for as long as two years, are focused on expanding additive manufacturing (AM) to include the use of stronger plastics and metals as well plastics recycling and improving production on Earth. One company is developing the ability to print next-generation electronics aboard the International Space Station (ISS).
Several of the proposals are developing materials and technologies that would be used in a new additive manufacturing system called FabLab that NASA will launch to the station. The new printer would use multiple materials instead of just plastic feed stock to print parts and tools.
BOTHELL, Wash. (Tethers Unlimited PR) — NASA has selected TUI’s HYDROS-C thruster for demonstration on the first Pathfinder Technology Demonstration (PTD) CubeSat mission, planned for launch in early 2019.
The HYDROS-C thruster, developed under a NASA Small Business Innovation Research (SBIR) contract and matured to flight-readiness under a NASA Tipping Point Technologies Public-Private Partnership, is a revolutionary space propulsion technology that uses water as propellant.
BOTHELL, Wash. (Tethers Unlimited PR) — Tethers Unlimited, Inc. (TUI) announced that it has successfully delivered the first flight unit of its new K-Band transmitter for small satellites to a confidential customer.
Developed under a Small Business Innovation Research contract from the US Army’s Space and Missile Defense Command, the SWIFT®-KTX transmitter builds upon TUI’s high-maturity SWIFT software defined radio platform to enable satellites as small as a loaf of bread to transmit data at rates exceeding 100 megabits per second (Mbps).
SWIFT-KTX provides small satellites with a high-throughput downlink in K-band. When paired with the next generation SWIFT baseband processor and sufficient link margin, real data rates of 500 Mbps or more are achievable using high order modulation (>3 bits/Hz) and Turbo/LDPC encoding.
Two transmitter front-end modules are currently in development. Each module includes a two 2W PAs that directly drive two switchable WR-42 waveguide interfaces for left/right antenna polarization agility. A third ≈10 dBm waveguide output is available before the PAs for driving TWTAs and integrated K-band ESAs.
>500 MHz real modulation bandwidth
Two discrete designs covering approximately:
≈ 3 dBm saturated output power w/ ≈20 dB adjustable range
Three switchable WR-42 waveguide outputs (two w/ HPAs)

6-36V unregulated DC
Integrated latch-up/fault detection and protection
Flexible mounting options
Flanges for deck mounting
Ears for CubeSat rail mounting
Current generation 50 MHz baseband processor: ≈3W
Next generation 500 MHz baseband processor: ≈15W
K/Ka-band module power consumption for 33 dBm output: ≈16W
BOTHELL, Wash. (Tethers Unlimited PR) — Tethers Unlimited, Inc. (TUI) announced that it has successfully delivered the Refabricator payload to NASA in preparation for launch to the International Space Station (ISS) later this year.
The Refabricator is a mini-fridge sized experimental payload that combines a plastics-recycling system with a 3D printer. NASA will use this payload to demonstrate the ability for astronauts to recycle plastic waste and use the material to create new parts and tools to support long-duration manned missions to the Moon, Mars, and deep space.
Tethers Unlimited (TUI) will develop a collaborative robotics platform for use aboard the International Space Station with the assistance of NASA funding.
The space agency has selected the company’s AstroPorter proposal for funding under its Small Business Innovation Research (SBIR) Phase I program. The contract is worth up to $125,000 over 13 months.
‘TUI will develop an AstroPorter payload for Astrobee to perform collaborative robotics tasks with TUI’s MANTIS – an EXPRESS Rack payload with a robotic arm for telerobotic operation of experiments on the ISS,” the proposal summary states. “AstroPorter will interface with Astrobee through the dedicated payload bay and function as a platform for transporting equipment and other stowed material around the ISS.”
