The philatelic association of China Aerospace Science and Technology Corporation 6th academy in Xian (responsible for liquid rocket engine development and production) issued some designs for Chang’e-5 T1 commemorative envelopes. Some information are remarkable:- The launch vehicle is called CZ-3C/G2- The planned landing area seems to be in the vicinity of Huofutan Township (活福滩乡; Postal Code 011809) only few Kilometers eastwards from the primary Shenzhou landing area in the vicinity of Honggeer Banner (红格尔苏木 Postal Code 011819)
Launched (sic!) is planned in a narrow window at 17:59:xx UTC on October 23 and flyby is to occur nominally on October 28 at 00:33 UTC
Chang'e 4M if this post is a good indication.
The thread title is 5-T1, which I interpret as the first technology demonstrator for the CE-5 mission.I'm just wondering if CE-4 is on the schedule in any way. A Space.com article refers to this mission as CE-4, which I'm pretty sure is wrong.
No. '4M' is another mission that will be launched along with the Chang'e-5-T1 mission.
Thanks. That is what I thought. Good to have it confirmed.

A Space.com article refers to this mission as CE-4, which I'm pretty sure is wrong.Chang'e-4 is being evaluated by the Chinese scientists at this time. The probe was developed as a back-up to Chang'e-3 and I suppose that the actual evaluation of the mission is related to the problems registered with the Yutu rover.From http://news.xinhuanet.com/english/china/2014-10/10/c_127083174.htm "China's ailing moon rover weakening: designer""Yu said the Chang'e-4 mission is under further analysis.As the backup probe of Chang'e-3, Chang'e-4 will verify technology for Chang'e-5. The more sophisticated Chang'e-5/6 missions are aimed for tasks including unmanned sampling and returning to Earth."
4M (Manfred Memorial Moon Mission)4M or Manfred Memorial Moon Mission is a mission dedicated toLuxSpace founder, Prof. Manfred Fuchs, who died early this year. Themission is a lunar flyby of a spacecraft that is attached to the laststage of a Chinese Long March 3C rocket. The launch is scheduled forOctober 23, 2014 at 1800 UTC.Beijing plans to launch a Lunar spacecraft on a journey lasting 196hours that should take it around the Moon before returning and re-entering the Earth's atmosphere. It will carry a 14 kg payload knownas 4M-LXS which was developed at LuxSpace.The 4M-LXS amateur radio payload will transmit on 145.980 MHz +/-2.9kHz (-40°C to +125°C), Doppler max: -2200Hz, +1000Hz. Thecontinuous transmissions will start 4670s (77.8 minutes) after launch(-0, +600s). Five successive 1 minute sequences are sent during the 5minutes cycle. The digital mode JT65B will be used, this can bedecoded by radio amateurs using the free WJST software, there willalso be 'human readable' tone transmissions. See the transmitsequence description on page 14 of 4M Mission: a Lunar FlyByexperiment available athttps://ukamsat.files.wordpress.com/2014/09/lxs-4m-eme2014-a4-v3.pdfDuring the lunar flyby, the range will be 399,636 km at the most andthe distance to the Moon will be between 12,000 and 24,000 kmdepending on the final injection vector. The transmitter produces 1.5watts to a simple Monopole antenna which should give a Signal toNoise ratio ( S/N) comparable to amateur moon bounce (EME) signals atthe Earth's surface.LuxSpace encourages radio amateurs around the world to receive thetransmissions and send in data. There will be a number of Experimentsand Contests with prizes to the winners in each experiment andcategory. Details are given on page 19 of 4M Mission: a Lunar FlyByexperiment.A Java client will be made available to automatically send the WSJTALL.TXT and the decoded.txt files to a central database.The orbiter is one of the test models for Beijing's new lunar probeChang'e-5, which will be tasked with landing on the moon, collectingsamples and returning to Earth. The launch is aimed at testing thetechnologies that are vital for the success of Chang'e-5. The orbiterwill be launched into Lunar Transfer Orbit (LTO) then will perform aflyby around the Moon and re-enter the Earth's atmosphere after 196hours (9 days).The orbiter arrived by air in Xichang, Sichuan on Sunday, August 10and was then transported to the Xichang Satellite Launch Center.The integration of the LX0OHB-4M amateur radio payload was completedon Sunday night, October 12 and is now ready to launchThe onboard clock has been adjusted to start JT65B (145.980 MHz) atthe UTC minute +/-1 second. It is likely to drift during the mission,and manual offset introduction will be required after a week or so.The launch date is October 23 at 1800 UTC.Beginning of transmission of 4M will start between 1917 UTC and 1927UTC. Refer to the provided maps and animations links in the blogsection (see also older messages) to determine your visibility.Alternatively, use the 'tracking' section where you can compute yourtracking elements by introducing your geographic coordinates. Thetable can be copied/pasted into a text file. As the apparent movementwill be close (and closer) to the one one of the Moon, manualpointing is easy but for the largest arrays.The link budget is quite tight, but the first hours should givecomfortable signals. QSB is to be expected.As JT65B is used: please remind those not yet too familiar with itthat the receiver must not be tuned during the transmission. Adedicated webpage is being written to detail the procedure.A dedicated java application is also available to automaticallytransmit the decoded messages to the 4M website and ease the datacollection. (Thanks to LSE Space). Alternatively, you can also sendthe decoded messages by eMail, sending the ALL.txt file.For those not wishing to use JT65B, please record the signals(11025s/s, 8or 16 bits, mono), taking care not to saturate therecording and NO MP3 please.SpectrumLab is an excellent choice, although some may wish to usesimpler recording software.You can imagine that the team is quite eager to receive the firstreports, so, do not hesitate to mail immediately, send decodedmessages or even phone or text me at +352 661 678 986.Our friends of IC CMalaga are also quite eager to receive theresults of their radiation dosimeter experiment.Basic rules of the contest have been delineated in the blog section.Complete rules will be published soon.Stay tuned on our website or Facebook page.The following is a tentative set of orbital elements that shouldremain valid from the launch to at least up to the October 27 whenusing usual classical and simple tracking software which does notintegrate Moon.1 99999U 14298.79728009 .00000066 00000-0 00000-0 0 000062 99999 030.6553 295.6956 9746689 147.2577 071.9585 00.10600338000010The following set is to be used after the flyby from October 28onwards1 99999U 14301.79728009 .00000000 00000-0 00000-0 0 000092 99999 049.9434 067.2017 6639865 045.9865 124.5019 00.06612018000010Details on receiving signals from the Manfred Memorial Moon Mission(4M) can be found athttp://moon.luxspace.lu/receiving-4m/Ghislain Ruy LX2RGEmail ruy at luxspace.lu with "4M Amateur" in the subjectManfred Memorial Moon Mission (4M) http://moon.luxspace.lu/Facebook https://www.facebook.com/LuxSpaceSarlThe launch will be broadcast by CNTV/CCTV:http://www.cntv.cn/ orhttp://english.cntv.cn/ orhttp://english.cntv.cn/live/p2p/index.shtmlInformation animations and some JT65B test files athttp://tinyurl.com/ANS292-AnimationsAMSAT-UK http://amsat-uk.org/Facebook https://www.facebook.com/amsatukTwitter https://twitter.com/AMSAT_UK
