So, for each kg in LEO the harvester has to produce 3. The first and most obvious customer is NASA; an orbital fuel depot would allow them to launch satellites on smaller LVs or launch larger satellites, allowing a choice between savings on the LV and increased capabilities on the spacecraft.

Organizational Theory Class

Well, Kattie is standing next to the small generator which provides electricity for our business during power outages during the summer monsoons. Fortunately this is enough for the outbound trip of a cargo tug.

Ms Dube has also been appointed as a member of the board of directors. Because the vehicle needs to aerobrake, it requires a reusable heatshield. That will drive up the dry mass of those systems, and by extension the propellant and overall cost of moving people to and from EML2.

The third fuel category is inert gases argon, xenon for ion engines; these can be stored as compressed gases or cryogenic liquids.


They have a lot going for them, including: The retirement of Mr Dijkgraaf is consistent with the board. Therefore let's try to find a route that takes about 7.

The engine starter solenoid is located near the base of the copilot's control stick and is activated by the magneto key switch. Cheap propellant in LEO is useful for missions to other planets or moons. The new engineering manager wanted to change this paradigm and attempted to implement protocols and policies that placed product quality over quantity and new product design.

Planetary Resources would like to retrieve water rich carbonaceous asteroids.

Farquhar Route Using an lunar gravity assist along with an Oberth enhanced burn deep in the moon's gravity well, EML2 is 9 days and 3. Plenty of metal oxides are available including iron, aluminum and titaniumbut carbon is rare. You could launch into a polar LLO, and then do multiple burns from there to EML2, but the propellantless launch option would only provide the first leg of the trip surface to LLO.

Put the perigee close enough to Earth and you can even get some aerobraking. From EML1, a craft with a heatshield can get to any low Earth orbit for 0. Without a heatshield, 3.

Electrical power is supplied by a 12 volt, direct current system. The Repurchase will be funded from Sasol.

Product details

Fuel can be harvested at the harvester's pace, shipped to the depot at the tanker's pace and accumulated for later use. Also, the STS crew rendezvoused with and attached a rocket motor to the Intelsat VI F-3 communications satellite to allow it to make an orbital maneuver.

At this point fuel can be transferred all the way to LEO; without a proper depot there are some inefficiencies, so only about 40 tons are delivered in each shrouded tanker requiring two standard tanker flights to fuel up. The sun boosts apogee as well as perigee.

This initial ton plant with 1 year of spares and a kg dextrous robot for remote repair operations would provide the first ISRU fuel as a proof of concept. This ignores the significant commonalities between systems; all the propulsion units are identical, all tankers identical other than the cargo adapter and all six ton ISRU plants are identical.

First let's establish some basics: If reliable fuel is available from Phobos then the lander might be redesigned to refuel both in LMO and on the surface, allowing it to carry more payload each way.

An elliptical orbit from such a launcher would have its line of apsides pass through the launch location, which would be orthogonal to the Moon-EML2 line. Whatever could be reused in some way is unknown, but the real value is in the forensic analysis of how the satellite weathered in the GEO environment over a known period of time.

Low Earth orbit takes anywhere from 9. When times are good and above average returns are generated, other departments may make extra demands for more funds. Ultimately the cost of shipping along this route is the cost of spares and replacement of the various ISRU bases, depots and tugs. Let's also assume that spares are supplied as ton packages by Falcon 9, two per synodic period.

Jim seems sandwiched between Phalen and Short. Each launch site has a specific, most-efficient inclination.
