Lockheed Martin enlists Tyvak and Telesat for Space Development Agency contract


Lockheed Martin's satellites for the SDA will be about 150 to 200 kilograms and will use Tyvak’s Mavericks platform

WASHINGTON — Lockheed Martin will build 10 satellites for the Pentagon’s Space Development Agency using small buses from Tyvak Nano-Satellite Systems. The company also has enlisted Canadian satellite operator Telesat to provide technical advice.

Lockheed Martin and York Space Systems were selected by the SDA to each produce 10 satellites that will be part of a mesh network in low Earth orbit known as Transport Layer Tranche 0.

Eric Brown, Lockheed Martin’s director of military space mission strategy, told SpaceNews that the satellites will be about 150 to 200 kilograms and will use Tyvak’s Mavericks platform.

“We got a very strong offer from Tyvak,” he said. “We are designing for production, to generate volume.”

SDA is buying 20 satellites to launch in 2022 but plans to deploy hundreds more in the future.

Telesat will be part of Lockheed Martin’s team as a technical advisor. “We brought in Telesat to provide insight into networking processes you’d expect on the commercial side,” said Brown.

Lockheed Martin previously worked with Tyvak on a mesh network in space demonstration known as “Pony Express.” Brown said the expertise gained in that demonstration helped Lockheed Martin win the $187.5 million SDA contract. The Transport Layer has to route data from ground station to satellites in orbit and back to the ground to wherever military forces need the data.

Seven of the 10 satellites under the SDA contract must have four optical inter-satellite cross links per spacecraft. The other three must have two cross links and two downlinks.

Brown said Lockheed Martin has selected a supplier for the optical links but could not disclose the name at this time.

The satellite downlinks have to connect to the military data networks Link 16 and Integrated Broadcast System. Future satellites are expected to have to communicate with the Lockheed Martin-made F-35 combat aircraft which uses a different data network known as the Multifunction Advanced Data Link.

‘We’re beginning to anticipate requirements for F-35 in the future,” said Brown.

SDA Director Derek Tournear said that even though Lockheed Martin’s satellites are more expensive, the agency selected the company because it provided overall higher value.

Brown said SDA couldn’t rely only on space companies to build the Transport Layer and needed a contractor with “awareness of the overall mission, not just the space piece but across domains.”

You may soon be able to ride to the edge of space from Alaska in a Balloon Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere. Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune,  The Anchorage Daily News  reported on Sunday. The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium. Each passenger could pay an estimated $125,000 for a six-hour journey. Mark Lester, CEO of Alaska Aerospace Corp., said the high-altitude rides will be available from Kodiak in a few years and will ...

Committee recommends review of planetary protection policies

Committee recommends review of planetary protection policies WASHINGTON — The NASA Advisory Council has recommended that NASA review its existing planetary protection guidelines to balance the needs of science and exploration, an effort that could set the stage for a similar revision at the international level. The council, during a two-day meeting at NASA Headquarters Dec. 10–11, adopted a recommendation calling on NASA to establish an interdisciplinary committee of experts to review the agency’s current requirements for preventing contamination of other worlds by NASA spacecraft as well as any contamination of the Earth by materials brought back from those worlds. “NASA should establish a multidisciplinary task force of experts from industry, the scientific community, and relevant government agencies, to develop U.S. policies that properly balance the legitimate need to protect against the harmful contamination of the Earth or other celestial bodies with the scientific, social, and e...

Surprise! There's more water on Jupiter than anyone thought

Surprise! There's more water on Jupiter than anyone thought Jupiter  appears to have more water than anyone expected. Newly released data from  NASA's Juno probe shows that water may make up about 0.25% of the molecules in the atmosphere over Jupiter's equator. While that doesn't sound like much, the calculation is based on a prevalence of water's components, hydrogen and oxygen, three times more than at the sun. The new measurements Juno obtained are much higher than a previous mission suggested. The surprise result has scientists delving deep again into results from  NASA's Galileo mission to Jupiter , which obtained drier results in 1995 when engineers deliberately threw the spacecraft into Jupiter's atmosphere. (Galileo was low on fuel and NASA didn't want to take the chance, even if it was a slight one, of the spacecraft accidentally crashing on a potentially habitable icy moon.) Reconciling the results from Galileo and Juno is key for sc...
