Spinosaurus had a tail designed for propulsion in water, a forward-leaning center of gravity good for swimming, and curved claws more suited to catching prey in water than to walking on land. Read more: https://t.co/6rY2gtRons #NatGeoReimaginingDinos
The last known variant of the Dom and the final model in that line, the unit features various improvements such as dust filters for the rear thermonuclear jet propulsion and a back mounted antenna for increased communication capabilities.
The spaceships, use brand new physics and material science, to create a Weird Field, which provides inertialess propulsion at speeds of millions of kilometres per hour.
The spaceships do look a little odd though.

Interesting designs for transport craft and LLO/LEO propellant depots using nuclear propulsion and lunar ISRU-derived propellants.
They get to the Moon in about 24 hours using ~8km/s of deltaV.

Radioisotope Electric Propulsion has been dismissed because of the terribly low (3-8 W/kg) power density of the energy source.
However, newer Stirling generator ASRGs manage 90 W/kg, making them finally interesting for 100kg-scale probes in deep space.

@JusttheZooofUs Wayne Barlowe's "Expedition" aliens - he made a design choice that they wouldn't have eyes or jaws, and the brains are in the torso, some have fore-and-aft legs, or fly using jet propulsion, or biolights. It's incredibly detailed and well thought out.
ThermaSat is a small solar thermal energy system for a CubeSat that stores heat in molten salt and then uses it to boil water to 700K+ for propulsion.

Isp will be atrocious but deltaV requirements are low anyway.
Solid anti-hydrogen is shot at a sail coated in uranium to create an interstellar propulsion system. Exhaust velocity is variable, engine mass is minimal and the antimatter amount needed is tiny.

On June 17th 1952 e.v. Jack Parsons, co-founder of the Jet Propulsion Laboratory, is killed in an explosion in Pasadena California. He has been one of the few who truly propelled the Current ahead, especially in his breaking with the Crowleyan mould and looking for alternatives.
Before the nuclear pulse propulsion Orion, there was Helios.
20 GJ explosions inside a 10m wide chamber heated hydrogen gas to 6000K.
The walls had to withstand 3-5 kilobar pulses and 4000K surface temperature...

按NASA官网上的前瞻设计图，未来的登月和火星计划将要通过”深空门户“空间站进行中转。这个初期计划运行在月球轨道上的空间站最大亮点就是搭载的离子推进系统（Power Propulsion Element），依靠太阳能发电来推进。4000比冲的梦想，愿该计划最终得以实现。
@DragonCobolt So, he operates like the 2099 Punisher.
His only propulsion is his desire to kill Nazis.
I have been unable to find much information on what @AtomosSpace is offering.
They mention nuclear technology and higher specific power on-orbit propulsion...

Revisiting a character design I left untouched for too long. Ankh, a tiger shark DPV (diver propulsion vehicle) racer and mechanic. 🦈🏁
Every business starts small! Work hard and you too can afford that pneumatic propulsion prosthesis one day.

@dsfpspacefl1ght @paul_drye Nuclear-electric propulsion. The heat radiators are a dead giveaway
