NASA dicit:

The private-public partnership with NASA and Redwire will demonstrate the ability of a small spacecraft – OSAM-2 (On-Orbit Servicing, Manufacturing and Assembly) – to manufacture and assemble spacecraft components in low-Earth orbit.

Northrop Grumman dicit:

SpaceLogistics LLC, a Northrop Grumman Company, has partnered with DARPA on the agency’s Robotic Servicing of Geosynchronous Satellites (RSGS) program.

The groundbreaking mission features the first-ever commercial robotic servicing spacecraft, known as the Mission Robotic Vehicle (MRV), and aims to expand the market for satellite servicing with advanced robotics technology.

The company is also developing Mission Extension Pods (MEPs) to be installed by the MRV. The new pods act in place of the propulsion system of aging satellites and provide six years of life extension.

OSAM-1

NASA dicit:

OSAM-1 (short for On-Orbit Servicing, Assembly and Manufacturing mission 1) is a robotic spacecraft equipped with the tools, technologies, and techniques needed to extend satellites’ lifespans – even if they were not designed to be serviced on orbit.

During its mission, the OSAM-1 servicer will rendezvous with, grasp, refuel, and relocate a government-owned satellite to extend its life. But OSAM-1’s effect will not end there. The benefits are many. OSAM-1’s capabilities can give satellite operators new ways to manage their fleets more efficiently, and derive more value from their initial investment. These capabilities could even help mitigate the looming problem of orbital debris.

Successfully completing this mission will demonstrate that servicing technologies are ready for incorporation into other NASA missions, including exploration and science ventures. NASA is also transferring OSAM-1 technologies to commercial entities to help jumpstart a new domestic servicing industry.

Cyclones on Jupiter

Wikipedia dicit:

The spectrometer mapper JIRAM, operating in the near infrared (between 2 and 5 μm), conducts surveys in the upper layers of the atmosphere to a depth of between 50 and 70 km (31 and 43 mi) where the pressure reaches 5 to 7 bar (73 to 102 psi). JIRAM will provide images of the aurora in the wavelength of 3.4 μm in regions with abundant H3+ ions. By measuring the heat radiated by the atmosphere of Jupiter, JIRAM can determine how clouds with water are flowing beneath the surface. It can also detect methane, water vapor, ammonia and phosphine. It was not required that this device meets the radiation resistance requirements. The JIRAM instrument is expected to operate through the eighth orbit of Jupiter.

Robotic Bees

NASA dicit:

Bee-lieve it or not NASA could send a swarm of robot bees to the Red Planet. Researchers are taking inspiration from the insect world to develop Marsbee, a bold new idea that could enhance the exploration of Mars.

This is a research study within the NASA Innovative Advanced Concepts (NIAC) program. NIAC is a visionary and far-reaching aerospace program, one that has the potential to create breakthrough technologies for possible future space missions. However, such early stage technology developments may never become actual NASA missions.

Mission Extension Pods

Northrop Grumman dicit:

SpaceLogistics LLC, a wholly owned subsidiary of Northrop Grumman, provides cooperative in-orbit satellite servicing to geosynchronous satellite operators using its fleet of commercial servicing vehicles. Our initial servicing vehicle, the Mission Extension Vehicle (MEV)™ docks with customers’ existing satellites providing the propulsion and attitude control needed to extend their lives. We have now introduced our next generation system, Mission Extension Pods (MEPs)™, which is a smaller and less expensive life extension service that only performs orbit control. The MEPs are installed by a robotic servicing vehicle called the Mission Robotic Vehicle (MRV)™ which can perform all the functions of an MEV while adding new robotic capabilities for additional services.

Our life extension services are compatible with virtually all geosynchronous satellites with minimal interruption to operations. They enable satellite operators to significantly extend satellite mission life, activate new markets, drive asset value and protect their franchises. SpaceLogistics delivers life extension services that are flexible, scalable, capital-efficient and low-risk. Our breakthrough innovations provide satellite operators unprecedented flexibility in asset deployment, enabling game-changing advances in financial and operating flexibility, and risk mitigation.
