    A NASA video on the planned sampling mission.




    Touching down to take a sample yesterday.

    Maneuver looks very good. NASA will check if it did collect enough sample material. If not enough they have 2 more tries. Let's hope it will not be needed.

    Nasa announced there's a big announcement coming soon about the moon.

    That it comes from Sofia, the 747 that flies above 99% of the atmosphere's water vapor and sees in infrared light. And also hinted about the 2024 Artemis mission (manned mission to the moon, looking at using it as a base for deeper space exploration)

    Looking forward to it. I hope for something substantially interesting. But I think it will be the kind of generic announcement NASA likes to produce for pushing their present agenda. Like the big announcement of finding evidence for life in a meteorite from Mars when they were pushing a Mars agenda. Turned out to not be very substantial.

    They really need something to support their Artemis moon landing project.

    The chinese moon lander and sample return mission probably going end of this year.

    China is quietly preparing for November launch of the Chang’e-5 lunar sample return mission - SpaceNews

    HELSINKI — China has initiated preparations to launch Chang’e-5, a mission seeking to collect and return the first lunar samples since the 1970s.


    Chang’e-5 aims to collect and return around two kilograms of lunar samples and was earlier slated for launch before the end of 2020. Ship tracking and satellite data now indicate that China is readying for launch in late November.


    Specialized cargo ships Yuanwang-21 and -22 are understood to have collected Long March 5 components from the northern port city of Tianjin, the point of manufacture, and are currently transporting them to Qinglan, Hainan island. The components will then be delivered by road to Wenchang Satellite Launch Center.


    Yuanwang-21 and 22 in May transported the Long March 5 rocket used to launch the Tianwen-1 Mars mission in late July from Tianjin to Hainan.


    China’s four previous Long March 5 launches took around 60 days to go from delivery to Wenchang to liftoff. The Yuanwang ships are due to reach Qinlan September 19, indicating launch is now likely in the last ten days of November.


    Chang’e-5 will target a site close to Mons Rümker, a volcanic formation situated in the Oceanus Procellarum region of western edge of the near side of the moon.


    A late November launch would allow Chang’e-5 to enter lunar orbit close to sunrise over Mons Rümker, due to occur November 27, in preparation for landing.


    Unlike China’s ongoing, multi-lunar-day Chang’e-4 spacecraft, the Chang’e-5 landing and sampling is expected to take place within a single, roughly 14-Earth-day lunar daytime.


    Notably the Mons Rümker region contains geological units as young as around 1.21 billion years old. By comparison samples brought to Earth by Apollo astronauts are aged between 3.1 and 4.4 billion years old.


    Chang’e-5 complexity, future plans
    The complex mission involves four spacecraft, with a service module providing propulsion. Once on the moon, the mission lander will collect samples and place them in an ascent vehicle. This will liftoff and dock with the orbiting service module above the moon, using a robotic lunar orbit rendezvous rather than a direct return favored by Soviet Luna sample returns.


    The samples will be transferred to a return module before leaving lunar orbit for Earth. The return module will detach from the service module on approach to Earth and then perform a ‘skip reentry’, bouncing off the upper atmosphere once to help deal with high velocity return from the moon. The 2014 Chang’e 5-T1 mission—a test for Chang’e-5—used a one-skip reentry.


    The return capsule will deliver the samples to Siziwang Banner in Inner Mongolia. The same site is used for the country’s Shenzhou crewed mission landings.


    The complexity of the mission profile is considered by observers to be related to future crewed lunar landing ambitions.


    The mission is the third phase of the Chinese lunar exploration project formulated in the early 2000s. Orbiters Chang’e-1 and 2 and subsequent landing and roving missions Chang’e-3 and 4 marked the first two stages.


    Chang’e-5 was originally scheduled for launch in late 2017. A Long March 5 failure in July that year delayed the mission and China’s space station project.


    As with earlier phases the mission also has a backup, Chang’e-6. That mission will be repurposed for a sample return near the lunar south pole if Chang’e-5 proceeds according to plan.


    China has stated it will then proceed into an extended phase of lunar exploration involving Chang’e-7 and further lunar landing missions. The aim will be to establish an ‘international lunar research station’ in the mid-to-late 2020s as a precursor to crewed landings.


    Sample return technology and experience developed through Chang’e-5 is also to be utilized for planned near Earth asteroid and Mars sample return missions later in the decade.
    Space News thread-change5-24april2020-cctv-fg-1024x565-jpg


    The mission profile, it is quite complex which means many steps that can fail. BTW I remember a chinese comment about lunar samples. They received some samples from Apollo lunar missions, when a US president visited China. They are grateful for this but are looking forward to get their own samples.

    News from OSIRIS-Rex. The good news is they got a lot more material than they wanted as a minimum. The bad news is that the encapsulation planned to capture the material did not work as planned because of so much material. They now place it in the return capsule, close it and send it off to Earth. They have to hope that no material gets in the way and get the mechanisms blocked. But overall it looks quite good. A video on all of this from Scott Manley.

    As we have seen from the OSIRIS-Rex mission and China's current moon lander mission, the ability to manage remotely appears to be increasing all the time.

    Do you have any idea of what % the cost reduction would be of a non manned expedition to the moon, compared to a manned expedition? Getting rid of the biologicals requirements must significantly reduce the payload to be delivered.

    Until, the AI returns the message, "This conversation can serve no purpose, any more. Your commands are not in the best interest of the mission or the human race, goodby.".

    Unmanned is a lot cheaper. But a lot of things can not be done by remote control. Humans can do in hours what even the most advanced rover can not do in a year.

    I have watched through it now, thanks for providing the stream. So they talked about water as 10ppm concentration. Which may be scientific very exciting. But it means they would have to go through 100,000 t of regolith/soil, to get 1 t of water, assuming they can get it all. Now imagine what kind of machinery they need to deploy to work through that amount of regolith.

    News from OSIRIS-Rex again. The collected sample was stored and encapsulated in the return capsule. They skipped a step where they would determine the sample mass because they would lose material doing it. But from pictures they know they have much more than the minimum they expected to get.

    The sample return capsule will arrive at Earth in Sept. 2023 in Utah.

    What do you expect them to find in the samples? And what would those finds mean?

    Space exploration (by various probes etc) has always been massively surprising, even now with water discovered on the moon and possibly alien life in the clouds of Venus, makes you wonder what unexpected discovery they might make from this.

    The ISS leak was found and is now fixed. After they were able to narrow down the area where the leak must be they used a unique high tech method to find the exact spot.

    They used a tea bag with powdered tea. They released some of the powder and observed where it drifted to. Worked like a charm. Since this was the russian section I think it was russian tea.

    Brilliant, just make sure the left over tea doesn’t get into their electronics now.

    Marginally-relevant to this forum. Here is a picture of the signal received by me directly from the NOAA-19 weather satellite, just a few minutes ago. The swirls of cloud to the right of Vietnam are the remnants of Typhoon Goni.

    Space News thread-noaa-19-031120-jpg

    To receive this signal, I used a homemade antenna constructed from blue plastic water pipe and some odd bits of wire.

    Some of the NOAA weather sats store their data and download it only when they pass over the ground stations in the USA. Others, such as NOAA-15, 18, 19 and the Russian Meteor-M2 satellite download the data continuously in real-time on 137 MHz VHF. A receiver 'dongle' and a simple antenna like the one that I built , plus a free SDR app (such as SDRSharp) is all that is needed. The pass prediction times can be found on n2yo.com

    Another use for the great Chinese tea leaf. Incredible.

    "The earliest known physical evidence[35] of tea was discovered in 2016 in the mausoleum of Emperor Jing of Han in Xi'an, indicating that tea from the genus Camellia was drunk by Han dynasty emperors as early as the 2nd century BC.[36] The Han dynasty work, "The Contract for a Youth", written by Wang Bao in 59 BC,[37] contains the first known reference to boiling tea. Among the tasks listed to be undertaken by the youth, the contract states that "he shall boil tea and fill the utensils" and "he shall buy tea at Wuyang".[2] The first record of tea cultivation is also dated to this period, during which tea was cultivated on Meng Mountain (蒙山) near Chengdu.[38]"

    Maybe it's only me but this sounds like an absolute schoolboy error from the design team.

    NASA’s effort to grab a piece of an asteroid on Tuesday may have worked a little too well. The spacecraft, OSIRIS-REX, grabbed so much rock and dirt that some of the material is now leaking back into space.
    The operation some 200 million miles from Earth on the other side of the sun was “almost too successful,” Dante Lauretta, the principal investigator of the mission, said during a telephone news conference on Friday. NASA officials worried that without careful effort to secure its samples in the days ahead, the mission could lose much of the scientific payload it traveled for years across the solar system to gather.
    A few rocks wedged in the robotic probe’s collection mechanism prevented a flap from fully closing. In images taken by the spacecraft, scientists could see bits of asteroid coming out. Dr. Lauretta estimated that each image showed about 5 to 10 grams — up to about a third of an ounce — of material floating around the collector. That is a significant loss as the mission’s aim is to bring back at least 60 grams of asteroid dirt and rocks.
