Unlike the other two recently launched missions to the moon, IM-2 will take a direct path to the moon and land 8 days after launch.
Surface operations will last less than 2 weeks before the brutally cold lunar night ends the mission.

Als Antwort auf AkaSci 🛰️ • • •Here is a map of the south polar region of the moon and the approx. landing site of the Intuitive Machines IM-2 lander.
The landing site on Mons Mouton is ~160 km from the South pole, a new record.
Mons Mouton is a wide, relatively flat-topped mountain, created over billions of years by lunar impacts. It is the tallest mountain on the moon at 6 km altitude.
The Permanently Shadowed Regions (PSRs) in the area are of special interest for presence of water ice.

Als Antwort auf AkaSci 🛰️ • • •Mons Mouton is named after Melba Mouton (Apr 28, 1929 – Jun 25, 1990) a trailblazing mathematician and computer programmer at NASA.
Mouton joined NASA Goddard in 1959. She became the head mathematician and led a group of ‘human computers’, who tracked the Echo 1 and 2 satellites, launched into Earth orbit in 1960 and 1964 resp.
In 1961, Mouton was the head programmer responsible for the Mission and Trajectory Analysis Division’s Program Systems Branch.

The 70-cm tall, 35-kg hopper contains propulsion and navigation systems, Lidar, and navigation and landing cameras. The hopper will communicate with the lander through an LTE system.
The hopper is named after computer programming pioneer Grace Hopper.

It landed alright, after an issue with the Laser range finder (someone failed to unlatch a safety latch before launch), but shortly after landing, the tall lander tipped over and came to rest on its side.
We can be quite sure that some changes have been made to the landing apparatus for IM-2.

JackDv: "There were lines that they forgot to uncomment out that are supposed to turn on the PA (commented out so it doesn't turn on while on the ground)."
That could explain why the spacecraft Power Amplifier (PA) (transmitter) is not turned on and requires a command from ground, which is unusual.
AkaSci 🛰️
Als Antwort auf AkaSci 🛰️ • • •@cosmos4u
Sounds like the PA issue with the AstroForge Odin spacecraft is real, i.e., it was caused by a failure to uncomment some code that turned the PA off, before deploying it for flight.
Matt Gialich: The PA was a know (sic) issue pre ship, not ideal, but not a show stopper for us.

To be honest, we do not know the reason why Athena failed to land upright. Could have been -
- the tall design
- landing on a rock (the terrain is rough and lighting is tricky at the landing site)
- landing at the edge of a crater
- landing on a steep slope
- incorrect altitude reading (the faulty laser altimeter was mentioned in the presser)
- incorrect attitude reading
- thruster problems
- too much fuel
- hard landing
- software bugs
- what else?
Mastodon Migration
Als Antwort auf AkaSci 🛰️ • • •Sure. There are lots of possibilities, and certainly they ran plenty of simulations that informed their design decisions. But, what we are really talking about is engineering margins. Starting with an inherently more stable basic design provides much more room for error.
This is something that airframe designers have always (or used to) regard as gospel.
