A mission where you bring along tons of scientific payload, and stay on Mars for 40 days to do some science. A mission with no payload just a Very Important Person. The lower the IMEO value, the more efficient.

Usually because it means lower propellant requirments, and may allow more payload. Figure 6 shows that the radiator-cooled gas-core nuclear rocket becomes more efficient higher Isp and lower specific weight as the thrust level is raised.

The missions depicted in the charts below were chosen with this in mind. You want IMEO to be as low as possible. Obviously you can lower IMEO by increasing the mission time, but who wants to spend years on a Mars mission? The scientific missions assume a 40 day stay on Mars to do science stuff.

The first gas-core nuclear rocket green curved line show an immediate performance improvement. This is the gas-core with no heat radiator, deliberately throttled down so it can make do with mere regenerative cooling. Its lowest IMEO is about 0. But the other gas-core rocket is even more powerful.

The gas-core nuclear rocket with a heat radiator blue curved line lowest IMEO is 0. If it is loaded at a IMEO of 0.

With performance this high, the 40 day stay on Mars becomes an appreciable fraction of the total mission time. So we now present "courier mode. No payload either, except for something way under 1 metric ton like a Very Important Person or a box of serum to treat the Martian Anthrax-Leprosy Pi epidemic.

A gas-core rocket with radiator on a courier mode mission hot pink curved line has truly jaw-dropping performance.

It can do an entire mission in only 80 days!

Just for comparison sake, the report includes a fusion rocket with typical high specific impulse but miniscule thrust orange curved line. This is because the fusion drive is low thrust and is power-limited. In order to accelerate up to cruising speed in sometime less than a decade it has to increase its thrust at the expense of the specific impulse.

Which sends its IMEO skyrocketing.Telestar Case Study Telestar International On November 15, , the Department of Energy Resources awarded Telestar a $, contract for the developing and . The engine is spherical.

The outer layer is the pressure vessel (since both the propellant and uranium gas needs lots of pressure to make this thing work), a layer of beryllium oxide (BeO) moderator (a neutron reflector to help the uranium undergo nuclear fission), and an inner porous slotted cavity liner that injects the cold propellant to be heated.
