Yutu-2 finds rocks that appear young

Yutu-2 has found a cluster of small rocks that appear relatively young, with little erosion.

The rocks also also appear as if they came from another place on the Moon.

Closer inspection of the rocks by the rover team revealed little erosion, which on the moon is caused by micrometeorites and the huge changes in temperature across long lunar days and nights. That anomaly suggests that the fragments are relatively young. Over time, rocks tend to erode into soils.

The relative brightness of the rocks also indicated they may have originated in an area very different to the one Yutu-2 is exploring.

Youth in this case is very relative. The rocks might be young when compared to the surface on which they sit, but they still could be more than a billion years olf.

Rocket Lab gets launch contract for lunar cubesat

Capitalism in space: NASA has awarded Rocket Lab the contract to launch the privately-built, for NASA, lunar orbiting cubesat CAPSTONE, designed to test technologies and the orbital mechanics required to build its Gateway lunar space station.

This quote says it all:

The firm-fixed-price launch contract is valued at $9.95 million. In September, NASA awarded a $13.7 million contract to Advanced Space of Boulder, Colorado, to develop and operate the CubeSat.

Using two different private companies, one to build the satellite and the other to launch it, NASA will get a lunar orbiter for just over $23 million. That total equals the rounding error for almost all NASA-built projects.

The launch is set for early 2021.

NASA delays commercial bidding process for its unmanned lunar landers

Capitalsm in space: NASA has postponed the bidding process for both the commercially-built lander that will bring its its VIPER lunar rover as well as the smaller landers that will bring simpler science packages to the Moon.

In the first case, it appears that the commercial companies wanted more time because VIPER is a heavier and bigger payload than their landers are currently designed for. In the second case, the reasons for the postponement are less clear, leaving the companies involved somewhat puzzled and in the dark.

Yutu-2 and Chang’e-5 complete 14th lunar day

China’s Yutu-2 rover and Chang’e-5 lander have successfully completed their fourteenth lunar day of operations on the far side of the Moon, and have gone into hibernation.

The report from China’s state-run news agency is, as usual, decidedly uninformative. It is written to make it appear that Yutu-2 traveled 367 meters during this most recent lunar day, when in truth that is the total distance since landing. In comparing this total with the total at the end of the thirteenth lunar day, we find that Yutu-2 actually traveled only ten meters.

The report also provided no other information about where the rover went, or what it has been doing, other than saying the rover and its instruments operated as “planned.” The article did not even include a picture, either new or old.

It is a shame that China operates in this secret way. They are doing good stuff on the Moon. If they touted it proudly to the world, in as much detail as possible, they would do themselves far more good.

NASA picks science payloads for 1st two unmanned private lunar landers

Capitalism in space: NASA has chosen the science instruments that will be put on the 1st two unmanned privately built lunar landers aimed at arriving on the Moon in 2021.

Two experiments will be flown on both landers. The Astrobotic lander gets an additional nine instruments, while Intuitive Machines gets three.

The most interesting tidbit from the press release is that NASA hopes to make “about two deliveries of scientific and research payloads to the Moon per year starting in 2021.” Seems overly optimistic to me, though in the long run the approach makes sense for NASA. These landers are relatively small and cheap, so the cost to fly a lot of them is not exorbitant. Under this arrangement, if one fails you simply figure out why and quickly fly another.

For this new American industry the approach also works. The companies will own the designs, so soon they will be able to market this technology to other customers, at what is historically record low prices for such a mission. The result is likely going to be the arrival of a swarm of new customers.

SpaceIL gets $1 million grant for building Beresheet-2

The Israeli non-profit that built Beresheet-1 has received a $1 million grant in order to pursue building Beresheet-2.

The Blavatnik Family Foundation has provided a one million dollar grant to SpaceIL to support the โ€œBeresheet 2โ€ spacecraft program and advance the goal of landing an unmanned Israeli spacecraft on the Moon. โ€œBeresheet 1โ€, launched on February 22, 2019, made Israel the 7th country in the world to reach the Moonโ€™s orbit. The new Blavatnik grant will enable SpaceIL to recruit a new CEO to drive plans for “Beresheet 2” forward.

It remains unknown whether Beresheet-2 will ever get built. The money is insufficient to build a new lunar lander. Moreover, several of SpaceIL engineers have left the company and formed their own private space business, partnering with Firefly Aerospace to build their own lunar lander.

China releases data and images from Yutu-2 and Chang’e-3

Yutu-2 on the far side of the Moon

The new colonial movement: To celebrate the completion of a year on the lunar surface, China has released the bulk of the data and images produced by the lander Chang’e-3 and the rover Yutu-2.

The link includes a nice gallery of images. I especially like the image to the right, cropped to post here. It shows Yutu-2 moving away from Chang’e-3 early in the mission. It also shows how truly colorless the Moon is. The rover proves this is a color image, but if it wasn’t in the shot you’d have no way of knowing.

And then there is that pitch black sky. I wonder what’s behind it.

India releases Vikram failure report

India’s space agency ISRO has released its investigation report on the failure of its lunar lander Vikram on September 7, 2019 to soft land on the Moon.

The Chandrayaan-2โ€™s Vikram lander ended up spinning over 410 degrees, deviating from a calibrated spin of 55 degrees, and making a hard landing on the moon, according to ISRO scientists. The anomaly, which occurred during the second of four phases of the landing process, was reflected in the computer systems in the mission control room, but ISRO scientists could not intervene to correct it as the lander was on autonomous mode, using data already fed into its system before the start of the powered descent.

According to the report, they are using what was learned to incorporate changes in Chandrayaan-3, their next attempt at putting a lander and rover on the Moon, presently scheduled to launch 14 to 16 months from now. That launch date, about six months later than previous reports, also seems more realistic. Initially the agency was saying it planned to launch Chandrayaan-3 in less than a year from project inception, by November 2020, a schedule that seemed rushed and ripe for mistakes.

Yutu-2 completes 13th lunar day

China’s Yutu-2 lunar rover and its lander Chang’e-4 have completed their thirteenth lunar day on the far side of the Moon and have been placed in sleep mode.

During the twelve lunar day the rover traveled about 12 meters, or about 40 feet.

The rover has found materials from deep inside the moon that could help unravel the mystery of the lunar mantle’s composition and the formation and evolution of the moon and the earth. Using data obtained by the visible and near-infrared spectrometer installed on Yutu-2, Chinese scientists found that the lunar soil in the landing area of the Chang’e-4 probe contains olivine and pyroxene which came from the lunar mantle deep inside the moon.

Due to the complicated geological environment and the rugged and heavily cratered terrain on the far side of the moon, the rover drives slowly but steadily and is expected to continue traveling on the moon and make more scientific discoveries.

Repost: The real meaning of the Apollo 8 Earthrise image

I wrote this essay last year, to celebrate the fiftieth anniversary of the Apollo 8 mission to the Moon. I think it worth reposting, especially because stories about Apollo 8 still refuse to show the Earthrise image as Bill Anders took it. Note that they took the picture on Christmas Eve, not Christmas day.
———————————————

Earthrise, as seen by a space-farer

Today is the fiftieth anniversary of the moment when the three astronauts on Apollo 8 witnessed their first Earthrise while in orbit around the Moon, and Bill Anders snapped the picture of that Earthrise that has been been called “the most influential environmental picture ever taken.”

The last few days have seen numerous articles celebrating this iconic image. While all have captured in varying degrees the significance and influence of that picture on human society on Earth, all have failed to depict this image as Bill Anders, the photographer, took it. He did not frame the shot, in his mind, with the horizon on the bottom of the frame, as it has been depicted repeatedly in practically every article about this image, since the day it was published back in 1968.

Instead, Anders saw himself as an spaceman in a capsule orbiting the waist of the Moon. He also saw the Earth as merely another space object, now appearing from behind the waist of that Moon. As a result, he framed the shot with the horizon to the right, with the Earth moving from right to left as it moved out from behind the Moon, as shown on the right.

His perspective was that of a spacefarer, an explorer of the universe that sees the planets around him as objects within that universe in which he floats.

When we here are on Earth frame the image with the horizon on the bottom, we immediately reveal our limited planet-bound perspective. We automatically see ourselves on a planet’s surface, watching another planet rise above the distant horizon line.

This difference in perspective is to me the real meaning of this picture. On one hand we see the perspective of the past. On the other we see the perspective the future, for as long humanity can remain alive.

I prefer the future perspective, which is why I framed this image on the cover of Genesis: the Story of Apollo 8 the way Bill Anders took it. I prefer to align myself with that space-faring future.

And it was that space-faring future that spoke when they read from Genesis that evening. They had made the first human leap to another world, and they wished to describe and capture the majesty of that leap to the world. They succeeded beyond their wildest dreams.

Yet, they were also still mostly Earth-bound in mind, which is why Frank Borman’s concluding words during that Christmas eve telecast were so heartfelt. He was a spaceman in a delicate vehicle talking to his home of Earth, 240,000 miles away. “And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas, and God bless all of you — all of you on the good Earth.” They longed deeply to return, a wish that at that moment, in that vehicle, was quite reasonable.

Someday that desire to return to Earth will be gone. People will live and work and grow up in space, and see the Earth as Bill Anders saw it in his photograph fifty years ago.

And it is for that time that I long. It will be a future of majesty we can only imagine.

Merry Christmas to all, all of us still pinned down here on “the good Earth.”
