Even without inter-power cooperation, US spacecraft will learn about the moon when they follow the Shanghai 3 spacecraft landing on the moon today

The Chinese spacecraft Shanghai 3 may add scientific data to those of the NASA spacecraft that will follow its landing: LADEE, LRO and Artemis spacecraft

updating: The Chinese spacecraft Shanghai 3 landed safely on the moon


After sending 12 humans to the lunar surface during the Apollo program, NASA remained committed to lunar science. It relies on completed modern spacecraft such as Clementine and Lunar Prospector and recent missions such as LCROSS and Grail that have enabled it to map the Moon, detect the presence of water ice and understand the irregular magnetic field of our cosmic neighbor. NASA's current missions to the Moon are designed to better understand our solar system, to inform the planning of future missions to the Moon and other planetary bodies, and to advance the development of the technology required for future destinations such as the asteroids and Mars.

Scientists using current spacecraft to explore the moon are getting a chance to collect new data thanks to the expected landing today of the Chinese lunar rover Changya 3. Researchers in the US and around the world see the Chinese operation as a new scientific opportunity that may potentially enrich studies and observations of the lunar atmosphere.

The robotic lander will reach the lunar surface just as the LADEE (Lunar Atmosphere and Dust Environment Explorer) spacecraft, the Lunar Rover (LRO) and two Artemis (Acceleration, Reconnection, Turbulence and Electrodynamics of Moon's Interaction with the Sun) spacecraft continue their scientific observations.
Although there is no cooperation between the US and China regarding these missions, the researchers will be able to collect interesting scientific data from the landing. The data will be available to the international scientific community.

The Lady spacecraft that studies the atmosphere and dust environment of the moon is equipped with technology to measure particles and may detect changes in the thin atmosphere that will be caused by the blowing of dust and exhaust gases to the surface by the Chinese spacecraft when it makes its way to the surface.
The original purpose of the spacecraft is to study the very thin atmosphere of the moon and the dust that surrounds it. Using the devices, the scientists hope to answer questions and whether the lunar dust, ionized by solar radiation, is responsible for the pre-sunrise glow above the lunar horizon as discovered in some of the Apollo flights.
Before and after Changa 3 lands, Lady will use a spectrometer to monitor gases that will be produced as a result of the landing - such as water, N2, CO and CO2. It will examine whether the landing produced detectable changes in the background environment of the gases in the lunar atmosphere.

The spacecraft launched in 2009 performed scientific activities and transmitted unique findings on the lunar exosphere as well as high-resolution photographs of the lunar surface.
On the day of landing, the spacecraft will perform eight maneuvers to scan the area near the landing site using the Lyman-Alpha Mapping Project (LAMP) device - an ultraviolet light imaging spectrometer. Another instrument on the spacecraft, LROC will be able to image the surface to detect the changes caused by the operation of Changa 3's landing engine.

Artemis instruments will allow LADEE data to be confirmed to more correctly interpret its findings from the landing.
The two spacecraft have been orbiting the moon since 2010. The first spacecraft P1 will pass about 200 kilometers from the surface of the moon and it will look for the signature of the Chinese spacecraft's plume in the fields of plasma and magnetic fields. The second spacecraft P2 will map the solar wind plasma and magnetic field conditions at the time.

  1. The gap in the American space program screams to the sky. They are behind. A bit shabby entering number 2 in the class that characterizes the current administration compared to Kennedy and Clinton (Mars). We learn from the landing even if we do not participate in it. We canceled the whole plan of landing on Mars and building rockets to travel there. We focus on satellites from around the world like the Israeli Space Agency. We are the nation of 250 million souls that saved the world twice from evil, and a third time from the USSR. stuttering

  2. Yes. I mean I hope there was an American landing and not much of what we have learned to believe and love is a lie. But I learned to be careful. The emphasis in my words was on the shift of the economic, scientific, powerful center of gravity to the East.

    There was a conspiracy theory:
    A. How can the flag in the photograph flutter in the wind, when there is no atmosphere on the moon.
    B. In addition, it seems to me that in terms of the shadow of the flag, something did not work out considering the position in relation to the sun.
    third. Where has the flag gone? I mean what made him disappear? Is there permanent wear and tear on the moon as a result of solar radiation.
    d. Add to that the difficulty of the Chinese to land a vehicle, with modern equipment, with modern chips, and tell me if you don't have doubts about the ability to land and carry out electronic control with the knowledge of 1969.
    God. The Americans did not repeat the experience too many times afterwards. The Apollo 13 experiment ended in near disaster, as a flight to prepare for the moon landing. Why?
    and. Why didn't they build a base on the moon, like in Antarctica? The oxygen can be collected from the almost empty space there or from the decomposition of water, similar to space laboratories. Water - not there. and protection from radiation and heat/cold is required. But beyond that, it's doable with existing technology. We would learn about space colonization from this.

  3. The Americans were quick to announce that the flag placed by Armstrong and Aldrin was no longer there. God forbid they find out that in 1969 there was no technology for landing on the moon. Americans are made an assumption: the moon is exposed to meteorites.
    There is no doubt that a Chinese landing on the moon, and from another angle the shipment of aircraft carriers to the Japan-China demilitarized zone and American silence, and from another angle: the continuous acquisition of Israeli and Western technology indicate a gradual shift in the economic and scientific center of gravity. God forbid the fall of the USA - it has many advantages. It's not necessarily a nicer world but it will be. You can also see the secrecy surrounding American weapons and rightly so, to a much higher degree than in the past. YF22 is only available to the US. Allies receive YF-35. And there's an RQ-180 stealth drone that looks like it landed in Roswell, and they rightly don't tell anyone anything about it. Not after the Iranians apparently landed an American stealth drone with Chinese assistance. In terms of weapons, the Americans are still easily able to eliminate an enemy army relatively easily. But economically - they have a clear difficulty, and therefore Obama closes the USA at the door.
