* SpaceX, for example, proposes a “VLEO,” or V-band low-Earth orbit (LEO) constellation of 7,518 satellites to follow the operator’s initially proposed 4,425 satellites that would function in Ka- and Ku-band.
* Boeing has a proposed global network of about 3000 satellites
Repairing and servicing all the satellites and building big things in space will create a self sustaining commercial economy with vast capabilities in the earth-moon-Lagrange-near earth asteroid space area
In orbit satellite servicing is being developed. DARPA and commercial ventures are looking at in orbit satellite repair and servicing.
Orbital ATK Mission Extension Vehicle 1 (MEV-1) is scheduled for launch in late 2018 and in-orbit testing with an Intelsat-built satellite by early 2019.
The Restore-L satellite is being developed by a company called Space Systems Loral in Palo Alto, California. The satellite will have autonomous navigation, dexterous robotic arms, a toolkit, and propellant to fuel up spacecraft that are out of gas.
By the company's estimates, Restore-L could launch as soon as 2020. Its first mission may be to refuel Landsat-7, which provides satellite imagery for the U.S. Geological Survey.
Rob Hoyt indicates that the challenges of effectively spreading off-world and colonizing the cosmos are overcome by making it easier to manufacture and assemble large systems and structures in space. This visionary physicist, engineer, and CEO is leading a team of scientists to overcome those challenges.
Rob co-founded Tethers Unlimited Inc. in 1994, and built it into a space and defense research and development firm. He is now building a spin-off, Firmamentum, to commercialize in-space manufacturing. Rob has won more grants from NASA’s Innovative Advanced Concepts program than any other researcher.
In October 2016, Firmamentum signed a contract with Space Systems Loral (SSL), a leading provider of innovative satellites and spacecraft systems, to prepare a flight demonstration of in-space manufacture of a component on a communications satellite. Firmamentum’s in-space manufacturing hardware is intended to fly as part of SSL’s “Dragonfly” program, which will demonstrate in-space robotic assembly of geostationary (GEO) communications satellites, enabling dramatic improvements in GEO satellite performance and mission flexibility. The Dragonfly program is funded under NASA’s Space Technology Mission Directorate’s (STMD) Tipping Point initiative to work with industry to advance the goals for robotic and human exploration of the solar system through the development of critical space technologies
With a launch date goal for 2017, Moon Express plans to send a rover to the moon’s surface to begin surveying its surface for the best locations for further operations to mine iron ore, water, rare Earth minerals, metals, carbon, nitrogen, hydrogen, and helium-3. Jain believes that because the challenges presented by moon exploration are similar to those presented by Mars – challenges such as high radiation and vast temperature differences – SpaceX and Moon Express have plenty of reasons to work together.
Moon Express wants to robotically mine the moon for water to provide fuel for commercial satellites and other missions.
Planetary Resources wants to robotically mine near earth asteroids for metals and water.
Bigelow Aerospace could put large expandable space stations into orbit or around the moon or on the moon or elsewhere.
The tens of thousands of satellites and the explosion in robotic capability could provide the economic momentum to rapidly transform the Earth moon system and near earth asteroids into a rapidly developing economy.
