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.

Our Mission Extension Vehicle (MEV-1), the first of its kind spacecraft to extend another satellite’s life, is now in orbit. MEV is designed to rendezvous and dock with satellites running low on fuel.

European Organisation of Telecommunications by Satellite S.A. (EUTELSAT) is a European satellite operator. Providing coverage over the entire European continent, the Middle East, Africa, Asia and the Americas, it is the world’s third largest satellite operator in terms of revenues. Eutelsat’s satellites are used for broadcasting nearly 7,000 television stations, of which 1,400 are in HD, and 1,100 radio stations to over 274 million cable and satellite homes. They also serve requirements for TV contribution services, corporate networks, mobile communications, Internet backbone connectivity and broadband access for terrestrial, maritime and in-flight applications.

The Mission Extension Vehicle (MEV) is a spacecraft concept proposed by ViviSat. ViviSat was a 50/50 joint venture of aerospace firms U.S. Space and ATK created in 2010 for the purpose of designing, producing and operating the MEV-program. The purpose of the MEV-spacecraft is to operate as a small-scale in-space satellite-refueling spacecraft. Since the original conception of the MEV-program by the ViviSat-company, the Vivisat-venture has been shut down and the company dissolved by ATK (one of the partners in Vivisat) in April of 2016. The MEV-program has continued as a solo-project of ATK. ATK has been since purchased by Northrop Grumman in 2018, and is now Northrop Grumman Innovation Systems. The MEV-program continues under Northrop Grumman.

As humans plan expeditions to places such as the Moon and Mars, biomining could offer a way to obtain needed materials on other planetary bodies rather than bringing them from Earth. However, microbes and rocks interact differently outside of Earth’s gravity, potentially affecting output from extraterrestrial biomining. A new investigation on the International Space Station is studying how microbes grow on and alter planetary rocks in microgravity and simulated Martian gravity.

A Soyuz spacecraft consists of three parts (from front to back): a spheroid orbital module, which provides accommodation for the crew during their mission; a small aerodynamic reentry module, which returns the crew to Earth; a cylindrical service module with solar panels attached, which contains the instruments and engines.

The orbital and service modules are single-use and are destroyed upon reentry in the atmosphere. Though this might seem wasteful, it reduces the amount of heat shielding required for reentry, saving mass compared to designs containing all of the living space and life support in a single capsule. This allows smaller rockets to launch the spacecraft or can be used to increase the habitable space available to the crew (6.2 m3 or 220 cu ft in Apollo CM vs 7.5 m3 or 260 cu ft in Soyuz) in the mass budget. The orbital and reentry portions are habitable living space, with the service module containing the fuel, main engines and instrumentation.

Soyuz can carry up to three crew members and provide life support for about 30 person days. The life support system provides a nitrogen/oxygen atmosphere at sea level partial pressures. The atmosphere is regenerated through potassium superoxide (KO2) cylinders, which absorb most of the carbon dioxide (CO2) and water produced by the crew and regenerates the oxygen, and lithium hydroxide (LiOH) cylinders which absorb leftover CO2.

The vehicle is protected during launch by a payload fairing, which is jettisoned along with the SAS at ​2 1⁄2 minutes into launch. It has an automatic docking system. The ship can be operated automatically, or by a pilot independently of ground control.

Among the most striking features in the image are the rich colors of the clouds moving toward the Great Red Spot, a storm rolling counterclockwise between two bands of clouds. These two cloud bands, above and below the Great Red Spot, are moving in opposite directions. The red band above and to the right (northeast) of the Great Red Spot contains clouds moving westward and around the north of the giant tempest. The white clouds to the left (southwest) of the storm are moving eastward to the south of the spot.

All of Jupiter’s colorful cloud bands in this image are confined to the north and south by jet streams that remain constant, even when the bands change color. The bands are all separated by winds that can reach speeds of up to 400 miles (644 kilometers) per hour.
