Update from Jeff Plescia: The coordinates of the newly found impact site are 1.922N, 334.38E, and the elevation is about –1100 m with respect to the datum.
The position is about 31 km from the position determined by the seismic experiments and about 10 km from where the extrapolated tracking data suggested.
Understanding the actual location of both the impact and seismometers in the same coordinate frame allows a better derivation of the seismic velocity models.

The crash site of Apollo 16’s S-IVB stage has been pinpointed after a dedicated search for its impact location on the Moon.

As the third stage on the Saturn V booster, the S-IVB stages were purposely smashed into the Moon to perform seismic measurements used for characterizing the lunar interior.

However, on the Apollo 16 flight, a malfunction resulted in premature loss of tracking data for that mission’s SIVB. There was uncertainty in the stage’s impact location.

Position poorly defined

“I did finally find the Apollo 16 SIVB crater,” reports Jeff Plescia of The Johns Hopkins University’s Applied Physics Laboratory in Laurel, Maryland.

“It looks like the others, but its position was much more poorly defined since the tracking was lost prior to impact,” Plescia told Inside Outer Space.

The Apollo 16’s SIVB struck the Moon on April 19, 1972.

Plescia made use of super-powerful images produced by the LROC system on the NASA Lunar Reconnaissance Orbiter to identify the crash site.

Fifth human mission

Lifting off from Earth on April 16, 1972, Apollo 16 was the fifth mission to land humans on the Moon and return them to Earth.

The crew members for this expedition were John Young, Commander, Thomas Mattingly II, Command Module Pilot, and Charles Duke, Jr., Lunar Module Pilot,

Onboard their lunar lander – Orion — Young and Duke touched down in the Descartes Highlands of the Moon.

    hi,thanks for the image,if you have anymore of thse images of pas Apollo Expeditions or other spacecraft on the Moon let me know ok!
    thanks

    I hope we (people on earth) won’t make the moon’s surface a trash dump in the future.

  • ever find out where apollo 10s descent is at

    Hmmm……”It looks like the others, but its position was much more poorly defined since the tracking was lost prior to impact” …… Am I the only one who finds this statement incredibly nonsensical?

  • Mickey W. Law says:

    Could you please provide me with the Lunar Coordinates of the Apollo 16 S-IVB stage? Also, is there a website that compiles and archives coordinates for other Lunar archaeology items? Please know I will genuinely appreciate any information you can provide. — Mickey Law

    This is the kink of activity that made the moon people ban us.

  • Greg Zsidisin says:

    Leonard – Any idea if any of the LM Ascent Stage impact points are known? I would guess they weren’t tracked after being discarded in lunar orbit, but maybe they were?

  • Dave says:

    Do you happen to have the co-ordinates please?
    Just for fun..

    Yo’ waaaaaaaaz uuuuup I heard you trying to find some aliens… but guess there are no aliens because our lord (god) has only created one earth and you will not find any more habitable planets where the human race will be preserved… our insides up in hea’ up in hea’ yall is about to make me lose ma’ mind…. mas’ on’ mussion will not work it will be like the end of titanic where leo and what ever her name is is being held by him and hes like “never let go” and shes like “NOOO”.

  • jesus says:

    yo I’m back but baby don’t got back though… you know what I mean… contact me at this email…. mcginty601@gmail.com… who ever is reading this… tell me if you found my previous post funny or not
