I would admonish the top dogs of rocket science, those who would be the next legends, to avail themselves of an innovative liquid-fuel engine technology that leaves conventional liquid rocket engines gasping.  Traditional boundary layer cooling and other techniques for cooling the thrust chamber in order to prevent chamber degradation add weight and inefficiency that translate directly to reduction of payload capacity.  A superior technology exploits those rocket engine operating cycles in which thrust efficiency (specific impulse, Isp as you will) can be optimized by increasing the temperature allowance for propellant combustion.  Higher combustion temperatures exceeding 2000°C can be safely developed in thrusters made in a chemical vapor deposition (CVD) process using oxidation-resistant materials; moreover, cooling is entirely radiative, requiring no additional structure or materials with their onerous weight penalties.  Apogee insertion of heavier, more power-demanding satellites is thus facilitated, meeting the demands for increased capacity in satellites inserted into geosynchronous orbit from low-Earth orbit.

The thrusters at the heart of this advance are created inside out, inside a CVD reactor.  A thin layer of iridium metal is deposited on a mandrel the diameter of which equals the desired inner diameter of the thruster.  This layer is followed by a thicker structural layer of rhenium metal (m.p. 3,180°C).  Appropriate high-temperature emissivity characteristics are achieved by deposition of subsequent layers, as are the properties required for bonding the thruster to other components.  At this point I would not be free to discuss the proprietary process by which the mandrel is removed from inside the thruster, except to note that the iridium liner remains intact.  This issue can be resolved independently by most advanced propulsion laboratories, I presume. 

It is not unreasonable to expect up to 100 kilogram increases in payload capacity, worth millions of dollars, from the high-temperature thrusters.  Don't sit around on your wideness and miss the future.  Leaving this world alive just got three percent easier.  Each of us has his own reasons to cheer.
