Description

Apollo 15 landed in [/Palus%20Putredinis Palus Putredinis], just to the east of [/Hadley%20Rille Hadley Rille] and just north of [/Mons%20Hadley%20Delta Mons Hadley Delta]. It was the first lunar landing in which the astronauts were equipped with a motorized Lunar Rover, allowing them to explore and collect geologic samples over a much greater distance than had previously been possible.

Additional Information

  • The position of the Apollo 15 landing site given in the title line is from [/ULCN Davies and Colvin, 2000]. It is based on the later measured position of the Apollo 15 lunar surface experiment package (ALSEP) radio transmitter and the assumption that the lander touched down 110 m east and 56 m south of that location. The measured ALSEP location is itself probably uncertain by at least 30 m. The position plotted on the earlier [/DMA DMA]-prepared Topophotomap was 26.1228N, 3.6254E. The difference between the coordinate values (corresponding to an offset of about 370 m) represents a change in what is thought to be the correct coordinate system, and not a change in the estimate of the landing position relative to the lunar features.
  • Apollo 15's is the most northern one of the six manned landing sites.- DannyCaes DannyCaes Nov 26, 2008
  • NASA has selected the area explored by Apollo 15 as a [/RoI%20-%20Apollo%2015 Region of Interest] for investigation for a possible return visit in connection with its [/Constellation%20program Constellation program] of exploration.


Nomenclature

  • The [/IAU%20Nomenclature IAU Nomenclature] includes 14 minor astronaut-named [/landing%20site%20name landing site feature names] associated with Apollo 15 reportedly culled from a list of 81 names used during the mission planning. The following explanations of the 14 official names are copied from [/IAU%20Transactions%20XVIB IAU Transactions XVIB]:
    • [/Apennine%20Front Apennine Front]: The explored foothills of Hadley Delta which is part of the Apennine Mountain range on the eastern rim of Mare Imbrium.
    • [/North%20Complex North Complex]: Complex of hills, craters, scarps and apparent flow fronts to the north of the landing site.
    • [/South%20Cluster South Cluster]: A cluster of secondary craters located to the south of the landing site. The western part of the cluster was explored on the second EVA.
    • [/Plain Plain]: A flat mare region on which the LM landed east of [/Rima%20Hadley Rima Hadley].
    • [/Terrace Terrace]: Slight projection of a basalt-mare unit out into [/Rima%20Hadley Rima Hadley]. The farthest sampling point to the west on EVA 3 was in its vicinity.
    • [/Bridge Bridge]: Crater within [/Rima%20Hadley Rima Hadley] whose rim appears to form a bridge across the rille. Crater was used as a landmark.
    • [/Dune Dune]: Crater named for a dune-shaped structure on the southeast rim. Dune crater was the sampling site of Station number 4.
    • [/Earthlight Earthlight]: A crater named after an Arthur C. Clarke novel by the same name. The crater was described in detail during the second EVA.
    • [/Elbow Elbow]: Crater at a part of [/Rima%20Hadley Rima Hadley] resembling a bent elbow. The crater was the site of sampling station number 1.
    • [/Index Index]: A prominent crater near the landing site that served as the major landmark for orbital tracking and for LM descent.
    • [/Last Last]:This crater was supposed to be visited on the last traverse; it became the last crater to be approached during descent. The LM landed in its vicinity.
    • [/Rhysling Rhysling]: A crater named for Rhysling, the blind poet of "The Green Hills of Earth", a science fiction story by Robert Heinlein. Sampling station number 3 is 125 m west-southwest of the crater.
    • [/Spur Spur]: Crater located on a small spur of the [/Apennine%20Front Apennine Front]. The southernmost part of the second EVA traverse was in the vicinity of this crater.
    • [/St.%20George St. George]: In Jules Verne's "From the Earth to the Moon", the moon-bound crew members celebrated a successful launch by drinking a type of wine by the name of St. George. This 2.5 km in diameter crater on the [/Apennine%20Front Apennine Front] was the source of soil sample.



  • A Map in Eric M. Jones' Apollo 15 Image Library reportedly lists and identifies "all the named craters and craterlets in the neighborhood of Apollo 15's landing site, chosen by Joseph P. Allenand the crew." Most of the names were not adopted by the IAU. The following list compiled and investigated by Danny Caes gives the names on the map, and some others. Those Danny believes could be observed and webcammed through telescopes on Earth are preceded by a "+".
    • Alligator chain
    • Apollo 15 Target Point (a location, not a name). Note: the exact location of Apollo 15's LM Falcon was immediately north-northwest of crater Last, and not south of it, as shown in the map. The label "Apollo 15 Target Point" (on the map) is the location of Wolverine.
    • Arbeit
    • +Arrowhead, one of the large craters in the [/South%20Cluster South Cluster].
    • +Bennett Hill, west of [/Mons%20Hadley%20Delta Mons Hadley Delta].
      • According to page 84 of David M. Harland's book Exploring the Moon; the Apollo expeditions, Bennett Hill was named for Floyd Bennett, the member of the flight dynamics team who devised the steep descent which had enabled Apollo 15's LM Falcon to set down at the confined Hadley-Apennine site.
      • Surface photographs of Bennett Hill (LPI Apollo 15 Image Atlas).
    • +Big Rock Mountain, one of the peaks in [/Montes%20Apenninus Montes Apenninus], see: Swann Range, Swann Mountain, and Big Rock Mountain
    • Blinky (in [/South%20Cluster South Cluster])
    • Brandy

    • Canyon
    • Chain (in [/North%20Complex North Complex])
    • Cliff (beyond the western slopes of Rima Hadley)
    • Contact
    • Contour (on the northern slope of [/Mons%20Hadley%20Delta Mons Hadley Delta], with the fresh craterlet High a little bit further up the slope). Note: according to the LPI's descriptions, Contour should be visible in CDR David Scott's 500-mm SEVA photograph AS15-84-11237. See also Kipp Teague's medium and high resolution scans of the same photograph: AS15-84-11237 med-res and AS15-84-11237 high-res.
    • +Crackled Hills (?).
    • +Crescent, one of the large craters in the [/South%20Cluster South Cluster].
    • Crook (beyond the western slopes of Rima Hadley)
    • Crystal
    • Dandelion. Would you believe me if I say that the original meaning of this name is Lion's Tooth? Dandelion is from the French Dent-De-Lion, which means Lion's Tooth. See this Wikipedia page. Perhaps interesting to know: the planetary nebula NGC 6751 in the constellation Aquila is sometimes called the Dandelion Puff Ball because of its typical dandelion puff ball-like appearance.
    • Diamond
    • Distant (beyond the western slopes of Rima Hadley)
    • Dome (in [/North%20Complex North Complex])
    • Domingo (Spanish for Sunday)

    • +Hill 305 (also called Fresnel Ridge), west of [/Mons%20Hadley Mons Hadley].
    • Icarus (in [/North%20Complex North Complex]). Note: not to be confused with the pronounced farside crater [/Icarus Icarus]. If Apollo 15's Icarus was an official name, it would have been called Icarus-Apollo (because there's already an Icarus on the other side of the moon!).
    • [/Index Index]
    • Irwin's dunes Note: this name was not included on the map. It is mentioned on pages 152 and 162 of D.M.Harland's Exploring the Moon.

    • Notch (slightly south of Dune). See this Labeled section of the region northwest of Station 6 and Labeled section of the region northwest of the South Cluster (ALSJ).
    • November'. Note: during CDR David Scott's SEVA (Stand-Up EVA) it seems to have been impossible to observe and to photograph crater November, although it was a bright craterlet with raised rim. Perhaps November is noticeable on the PAN made at the VIP-site (the LRV's final parking location, east of LM Falcons landingsite). November is frequently mentioned on page 84 of David M. Harland's book Exploring the Moon; the Apollo expeditions. See also this photographic map of November and surroundings, from Eric M. Jones's Apollo Lunar Surface Journal.

The Wolverine case

Exploring the LPI's online scans of Apollo 15's Hasselblad photographs is always an interesting pastime, because it (this exploration) could reveal a series of unexpected discoveries, such as the name Wolverine, which must have been a small craterlet west of LM Falcons landing site. The name Wolverine is not included on the above mentioned map of the landing site (which shows more than 50 names of small surface formations in the neighborhood!).
 Wolverine is included in the LPI's descriptions below the 3 photographs AS15-82-11192, 11193, and 11194. The eastern Swann Range (the Apennine front) is noticeable in the background. The dark dot near the centre of each photograph is LM Falcon. The diffuse "fog" which is visible near the central part of each photograph is (was) probably a temporary moisty coating on the inside of the camera's lens system, or a thin layer of dust on the primary lens's outer surface. This effect is visible on several Hasselblad frames of Apollo 15, and also on several Apollo 12 frames.

 A message from Eric M. Jones of the online Apollo Lunar Surface Journal (ALSJ):
  Danny,
  During Apollo 15's EVA-3 drive from the LM to Station 9, at about 164:50:27 in http://www.hq.nasa.gov/alsj/a15/a15.trvsta9.html, Scott and Irwin encounter a large, shallow depression or crater. At 164:51:25, Irwin suggests that the inner slope is about 3 degrees and that the depth is 200 feet (60 m). During the post-mission debriefing, he said the slope was 5 degrees and the depth 150 feet (45 m). Using 4 degrees and 175 feet, the implied radius is 760 feet (230 m). At 164:51:01, Scott says that the depression appears to be elongated on an east-west axis. At 164:52:11, Irwin says he is going to call the crater "'Wolverine". The mascot of the University of Michigan athletics teams is the Wolverine. Scott, Irwin, and CMP Al Worden were all graduates of the University of Michigan.
  The shallow inner slope mean that the crater/depression doesn't show up well in the LROC images. Unless the Sun is within a few degrees of the horizon, the slopes facing the Sun will show up as slightly lighter in color and the slopes facing away from the Sun will be slightly darker. I have Sketch an approximate location of Wolverine on a detail from LROC image M117467833R, taken when the Sun was something like 20 degrees above the western horizon:
 M117467833R-Wolverine.jpg
  At 164:52:42, when they are on the north side of the depression, Irwin report a range to the LM of 600 meters, so the size and location of the outline I sketched using variations in brightness of the surface seems to be credible.
 
  Hope this helps.
 
  Eric Jones, ALSJ
