The Taurus-Littrow valley

It might not be Apollo 11, but during this 50th anniversary week of that mission, why not look at where the last Apollo 17 crew landed, in the middle of the Taurus-Littrow valley, as shown on the right in a Lunar Reconnaissance Orbiter (LR) image released by the LRO science team in 2018.

The image illustrates how ambitious NASA had become by this last Apollo mission. The Apollo 11 site was chosen because it was flat with as few risks as possible. By Apollo 17, the Apollo engineers and astronauts were quite willing to drop the LM down into this valley between gigantic mountains. Granted, the valley was more than 400 miles wide, but considering the risks of every Apollo flight, the choice was daring to say the least.

Taurus-Littrow also has a cluster of craters believed to have been formed by material flung out from the formation of 86-kilometer-wide Tycho crater about 100 million years ago. Tycho is 2250 kilometers from Taurus-Littrow, but the impact that formed it was violent enough that it cast material far across the Moon.

Nor is this location the most spectacular on the Moon. In fact, considering that all the manned and unmanned missions in total have probably covered less ground than a New York cab driver does in a single day, we have seen almost nothing there.


Another Google Lunar X-Prize team secures launch contract

Part Time Scientists, one of the teams competing for the Google Lunar X-Prize, has secured a launch contract through launch rideshare broker Spaceflight Inc.

Their rover will launch as a secondary payload. It is the broker’s job to secure that slot.

PTScientists plans to land its rovers in the moon’s Taurus-Littrow valley, the last place humans set foot on the lunar surface in December 1972, in the hopes of getting a closer look at how the Apollo moon buggy has survived over the past four and a half decades in the extreme temperatures and inhospitable conditions on the moon. “There is a reason we have chosen the Apollo 17 landing site,” said Karsten Becker, PTScientists electronics head, said in a call with reporters on Tuesday. “That is because the Taurus-Littrow valley is geographically very interesting — that is why it was chosen for Apollo 17 — but it is also a very-well documented site. There are many pictures where you can see that it is very flat, and that there are not that many stones laying around.”

The landing site has been chosen to be within reach of the Apollo 17 site, but not so close that it could risk damage to the NASA preservation heritage area. “We want to land 3 to 5 kilometers [2 to 4 miles] away from the [Apollo 17] landing site,” said Becker.

This team is now the fourth X-Prize team to secure a launch contract. All are hoping to launch within the next two years.
