#psychedforpsyche! Psyche has been selected by NASA as the 14th Discovery program mission, after Lucy. The mission aims to send a spacecraft in orbit around the M-type asteroid 16 Psyche, a metallic world theorized to be the exposed iron core of a former protoplanet the size of Mars. The spacecraft will launch in October 2023, with planned gravity assists of Earth in 2024 and Mars in 2025. It will arrive at 16 Psyche in 2030. The mission is led by the Arizona State University and Principal investigator Lindy Elkins-Tanton.

The Psyche Multispectral Imager is a derivative of the MSSS MSL camera: http://www.hou.usra.edu/meetings/lpsc2016/pdf/1366.pdf

Mission design win #3 for that camera.

Psyche has a Mars Flyby, and it uses a camera developed for Mars... but still I can't help feeling this thread belongs somewhere else than in the Mars section! (Also the new Lucy thread).

Oh whoops. I guess I'm still getting used to this forum! I just saw "Past and Future" on the subforum list and posted here. I didn't realise it was inside another subforum about Mars! Haha! Could a kind mod please move this thread to the "Cometary and Asteroid Missions" subforum? wacko.gif

Moved to Cometary & Asteroid Missions. smile.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Linda Elkins-Tanton asks in "PSYCHE AND SPACECRAFT 20161026":
QUOTE
Artist Peter Rubin and scientist Lindy Elkins-Tanton collaborate with Space Systems Loral and JPL to envision what orbiting the metal world Psyche might be like.
Pallasite contraction scarps, sulfur lava flows, frozen ejecta towers...what do you think might be there?

I answer,
QUOTE
Good question !
I would expect the impact craters to be relatively shallow, BUT due to the unusual stiffness of Psyche, there should be massive spalling on the opposite side.
Not sure what THAT looks like, on such a large scale.


Having looked at photos of spalling effects on Google image search, the most interesting ones are those with a "detached spall".
It would be really neat if Psyche found a loose one lying on the surface of the asteroid !

So maybe we'll finally get a cartoon asteroid..

Given the novelty of the type of object, I find this to be a pretty interesting mission. Not quite (pre-visit) Ceres-level, but high up there.

List of targets is out, along with diameter and flyby dates:

Short times between flybys in 2025 and 2027!

Those are Lucy flybys, no? I don't see any encounters for Psyche other than Psyche.

The threads are split now, got me a bit confused. I see this as the best summary both missions since I see no other recording of the telecon.

relevant to the mission:
Detection of Rotational Spectral Variation on the M-type asteroid (16) Psyche

QUOTE
The asteroid (16) Psyche is of scientific interest because it contains ~ 1% of the total mass of the asteroid belt and is thought to be the remnant metallic core of a protoplanet. Radar observations have indicated the significant presence of metal on the surface with a small percentage of silicates. Prior ground-based observations showed rotational variations in the near-infrared (NIR) spectra and radar albedo of this asteroid. However, no comprehensive study that combines multi-wavelength data has been conducted so far. Here we present rotationally resolved NIR spectra (0.7-2.5 microns) of (16) Psyche obtained with the NASA Infrared Telescope Facility. These data have been combined with shape models of the asteroid for each rotation phase. Spectral band parameters extracted from the NIR spectra show that the pyroxene band center varies from ~ 0.92 to 0.94 microns. Band center values were used to calculate the pyroxene chemistry of the asteroid, whose average value was found to be Fs30En65Wo5. Variations in the band depth were also observed, with values ranging from 1.0 to 1.5%. Using a new laboratory spectral calibration we estimated an average orthopyroxene content of 6+/-1%. The mass-deficit region of Psyche, which exhibits the highest radar albedo, also shows the highest value for spectral slope and the minimum band depth. The spectral characteristics of Psyche suggest that its parent body did not have the typical structure expected for a differentiated body or that the sequence of events that led to its current state was more complex than previously thought.

Water detected on Psyche - probably transported via impacts.

Thoughts on the official mission insignia? It looks very pretty in my opinion! I can't help but notice that they snuck in the colours of ASU into the insignia as well! ph34r.gif
