in-orbit

However, some of the alternatives to Ares-I have sufficient launch capability to launch spares with the Orion PLUS a airlock, robot arm and work area to allow for the Orion to do in-orbit maintenance of the ISS.

For four months in 2007, Chicago-based Boeing and partner Ball Aerospace & Technologies Corp. of Boulder, Colo., conducted in-orbit demonstrations of such a possible system, dubbed Orbital Express.

For Satellites, Service on High Andy Pasztor 2011

Again, NASA could chose to right-size its exploration architecture, Altair included, to be loftable on existing fleets of heavy launch vehicles that leverage the advantages of propellant depots and in-orbit assembly, or it could chose to waste the first decade of the Vision for Space Exploration designing and testing a NASA-only family of rockets that will fly once or twice a year at a ridiculously unaffordable average cost per flight.

NASA Leadership Vacuum - NASA Watch 2009

In spite of many NASA Human Spaceflight achievements in in-orbit construction and satellite servicing, the current plan abandons this, and doesn't encourage the commercial sector to take over.

It is true that use of a smaller launcher requires more launches and in-orbit assembly.

Dear Mr. Augustine - NASA Watch 2009

Breaking up elements of NASA activity is great for BIG GOVERNMENT but lousy for integrated use of assets, in-orbit or ground servers (Centers) assigned to manage the NASA mission.

The MUOS constellation is eventually expected to include four next-generation communication satellites and an in-orbit spare.

U.S. to Trim Commercial-Satellite Use Andy Pasztor 2012

NASA's top officials envision that aiming to approach and eventually land on an asteroid would require, among other things, a new type of spacecraft capable of withstanding high levels of radiation; some sort of in-orbit refueling capability; and more-capable and sustainable propulsion systems for transporting astronauts once they get outside the earth's gravitational pull.

Space Explorers Divided on Next Destination Andy Pasztor 2011

The most sophisticated current satellites can take at least a decade to go from early design to in-orbit operation, leaving them vulnerable to repeated funding fluctuations.

Since the demise of Saturn-V we've seen many such in-orbit refueling concepts thrown around (even ideas to just launch water and then separate it via electrolysis in space!), but the fact is since 1972 we've remained stuck in LEO because the cost of trying to do the job of a HLV with multitude of smaller launchers and EOR always ends up being significantly larger.
