The new trajectory to Mars. The Low-Energy-Transfer. This is exactly the right terrain for SpaceX ...isn't it?
Is SpaceX also discussing the possibility of a new shorter route to Mars?In 2014 Francesco Toputto and Edward Belbruno construct a new type of transfer from the Earth to Mars, which ends in ballistic capture. (https://arxiv.org/abs/1410.8856) It is called the Low-Energy-Transfer (https://en.wikipedia.org/wiki/Low-energy_transfer)Their work caused quite a stir. It would be the alternative to the Hohmann transfer. The short time window, the extreme deceleration manoeuvre, the high propellant velocities... all this would be obsolete after the route Toputto and Belbruno have calculated.The flight duration would be only slightly longer and above all a regular shuttle service to Mars could be established.It would be interesting if flight tests would be started at least once. So far I could not find any further public reports about this. Neither from NASA, ESA nor from SpaceX. The new trajectory was already described in 2014. This is exactly the right terrain for SpaceX ...isn't it?

Falcon 9 - Crew Dragon In Flight Abort Test
Launch date:
Launch site: KSC LC 39A
Payloads
Name: Crew Dragon In Flight Abort Test
Customers: NASA (CCtCap)
Type: Crew Dragon
Orbit: SO
Rocket
Name: Falcon 9
Version: FT
Cores
Serial: B1046
Block: 5
Flight-proven: Yes
Flying expendable
Details
SpaceX will launch a Crew Dragon capsule from LC-39A, KSC on a fully fueled Falcon 9 rocket and then trigger the launch escape system during the period of maximum dynamic pressure. As part of NASA'a Commercial Crew Integrated Capability program (CCiCap) this test will contribute valuable data to help validate Crew Dragon and its launch abort system. The Crew Dragon will be recovered by GO Searcher after splashdown in the Atlantic Ocean. This flight does not go to orbit. The booster and upper stage are expected to break up following capsule separation and there will be no landing attempt.

Crew Dragon | Launch Escape Demonstration
SpaceX is targeting Sunday, January 19 for an in-flight test of Crew Dragon’s launch escape capabilities from Launch Complex 39A (LC-39A) at NASA’s Kennedy Space Center in Florida. This test, which does not have NASA astronauts onboard the spacecraft, is…

Replay of explosion
ABORT! Through a tiny hole in the clouds, I managed to catch the abort and subsequent explosion! RIP B1046.

Last second clouds prevented me from getting shots of the separation and failure, but, a spectacular launch all the same!

Elon Musk talking about Starship after the In-Flight Abort Press Conference.
Elon ended up holding a kind of impromptu mini-press conference after the main press conference where he talked a little more about Starship and Raptor!
Sorry about the audio, it was just shot on my phone on a whim. Thanks for watching!
