Jonathan's Space Report No. 756 draft 2018 Nov 6 Somerville, MA --------------------------------------------------------------------------------------------- International Space Station --------------------------- Expedition 57 continues aboard the ISS with astronauts Gerst, Prokop'ev, and Aunon-Chancellor. The Kounotori 7 cargo ship remains at the ISS. It is scheduled to depart without its EP pallet, and the battery replacement spacewalks will occur no earlier than December. The Surrey RemDeb (RemoveDebris) spacecraft ejected its second cubesat subsatellite, DebrisSat-2, at 0615 UTC on Oct 28. RemDeb then observed DebrisSat-2 with its laser ranging instrument, a test of so-called Vision-Based Navigation (VBN) that could be used by an active debris removal mission to approach its target. The next Soyuz crew is scheduled for launch on Dec 3. BepiColombo ----------- The BepiColombo space probe was launched on Oct 20 from Kourou directly into Earth hyperbolic escape orbit. BepiColombo consists of two payloads, the ESA Mercury Planetary Orbiter (MPO) and the JAXA 'Mio' Mercury Magnetospheric Orbiter (MMO), together with two other modules, the MTM (Mercury Transfer Module, with electric propulsion) and the MOSIF (MMO Sunshield and Interface). MTM has 560 kg of xenon for its ion engine; it will be jettisoned just before Mercury orbit capture, in Dec 2025. The remaining three pieces will separate once they are in Mercury orbit. MTM will make a Mercury flyby and end up in solar orbit; by 2025 my orbit code may be good enough to figure out what the post-encounter orbit for it will be. MPO carries camers, spectrometers, a laser altimeter and an accelerometer among its experiments. MMO has particles, fields and dust instruments as well as an imager to map exospheric sodium atoms. Here are some summary details of BC's voyage based on the prelaunch trajectory; of course, actual details will change a little.

Parker Solar Probe ------------------ As of Oct 23 Parker Solar Probe became closer to the Sun than Mercury and had picked up speed to 50.3 km/s (heliocentric; 181,000 km/hr). On Oct 30 it broke the speed record of 68.6 km/s set by Helios 2 in 1976 and at perihelion Nov 6 at 0330 TDB (0328 UTC) it set a new speed record of 95.33 km/s and closeness-to-Sun record of 0.165 AU (24.8 million km). Relative to Earth (which you should not care about, but I know some of you do) Parker broke the Helios 2 record of 98.9 km/s early on Nov 5 and set a new record of 109.9 km/s on Nov 7 around 1900 UTC. Hayabusa-2 ---------- On Oct 15 Hayabusa-2 made a descent to only 22 metres above Ryugu in a touchdown rehearsal named TD1-R1-A. The next touchdown rehearsal is TD1-R3, was on Oct 25. Target Marker B, a 0.1m, 0.3 kg ball (one of five carried) was ejected from a height of 20 metres at 0237 UTC and landed on the surface. Operations will be suspended for a couple of months in Nov-Dec while Ryugu is behind the Sun as seen from Earth. OSIRIS-REX ---------- NASA's OSIRIS-REX asteroid probe continues its approach to asteroid Bennu. On Oct 15 the AAM-2 burn changed the probe's speed by 141 m/s and reduced its Bennu-relative velocity to 5.2 m/s. On Oct 17 the 1.1 kg, 0.4 x 0.4m TAGSAM sampler head cover plate was ejected into solar orbit. Current heliocentric orbit is 0.896 x 1.355 AU x 6.0 deg. On Oct 18 the probe was 5500 km from Bennu, but by Nov 6 it was only 170 km out. It was expected to arrive in Bennu's circa-35-km gravitational sphere of influence on Nov 30. New Horizons ------------ New Horizons, which flew past Pluto in 2015, is now 42.8AU from the Sun and 70 million km from the Kuiper Belt object (486958) 2014 MU69 "Ultima Thule", which it will fly past on 2019 Jan 1. The object's Hill sphere is probably about 79000 km in radius and the probe will take 3 hours to fly through it. ZU1CE58 -------- 5-metre asteroidlet ZU1CE58 passed through perigee 2018 Oct 19 at 1446 UTC, only 7274 km above the Earth, on a hyperbolic 7274 x -25650 km x 20.6 deg orbit. HY-2-02 ------- China's Haiyang er hao 02 xing (HY-2B) oceanographic satellite was launched on Oct 24. A small secondary satellite was launched along with HY-2B, called 'Tangguo Guan' (`Candy can'). It is owned by the online retailer AliBaba and will apparently send promotional messages to shoppers' mobile phones. Mass of Tangguo Guan has variously been reported as 20 and 29 kg. It apparently remains attached to the CZ-4B third stage, which lowered its orbit immediately after deploying HY-2B. Another secondary payload is China Aerospace's SPP (Space Proving Platform), one of whose experiments is ManWei Tech's DSB-01 which carries the DNA of eight Chinese people, described as the beginning of a program to explore technologies for interstellar migration. One of the Chinese news reports on this project shows an artist's impression of a 1U cubesat, but it's not yet entirely clear if SPP is really a cubesat or just another payload attached to the third stage. Soyuz return to flight ---------------------- A Soyuz-2-1B rocket was launched from Plesetsk on Oct 25, marking the Soyuz family's return to flight after the Soyuz MS-10 failure. The payload was Lotos-S No. 804, a signals intelligence payload (probably to be given the cover name Kosmos-2528). It was launched to a 245 x 900 km x 67.1 deg orbit, which it circularized at 2027 UTC Oct 26 to 900 x 910 km. Zhuque-1 launch failure ----------------------- The first orbital launch attempt by the private Chinese company Landspace failed to reach orbit. The three stage solid rocket Zhuque-1 was launched from Jiuquan on Oct 27. The first two stages, believed to be based on the DF-26 missile, operated correctly. The third stage ignited but at 37 s into its burn, 6m 42s after launch, it lost attitude control, and so provided little net velocity increase. As a result, the third stage and payload reached a suborbital apogee of 337 km and fell back to Earth, impacting west of Sumatra about 15 min after launch. CFOSat ------ On Oct 29 CALT/Beijing launched CZ-2C flight Y22 from Jiuquan carrying the China-France Oceanography Satellite. The satellite carries Chinese SCAT wind scatterometer and the CNES (France) SWIM radar altimeter instrument. Data processing and much of the instrument operations are under the aegis of CNES, but the satellite itself is controlled by China so I'll call it by its Chinese name, Zhongfa Haiying Weixing. The 700 kg satellite is a CAST-2000 bus built at the DFH factory. The CZ-2C also deployed a series of cubesats. Four of them were built by the Tiangyi Research Institute (whose marketing brand is SpaceTy): TY1-02 is Xiaoxiang yi hao 02 xing (XX-1 S/N 02). It carries a laser communications payload for Hangxing Guangwang Kongjian Jishu YG (LaserFleet) of Shenzhen. It is probably a 6U cubesat. TY1-03 is Xinghe ('Galaxy'), also called Tianfu Guoxing 1. The payload is a remote sensing satellite for Guoxing Yuhang Keji YG (ADA Space) of Tianfu New Area in Chengdu. It is probably a 6U cubesat. TY4-01 is Changsha Gaoxing , named after the Changsha High Tech Zone city. It is a 50 kg test satellite for Tianyi/SpaceTy's new '0805' bus; it reportedly carries an amateur radio payload. TY4-02 is Zhaojin-1, also called Tongchuan-1. It is a 6U cubesat for Tsinghua University with a gamma ray astronomy detector. It will also be used by Tongchuan City to test its commercial ground station (Zhaojin is a suburb of Tongchuan). In addition to the Tianyi satellites: Tianqi 1 is the first satellite in the 38-craft Tianqi constellation by Beijing Guodian HiTech Technology Co. Ltd. (Beijing Guodian Gaokeji YG). It will relay data from IoT devices. Its size is unknown. CubeBel-1 is a 2U cubesat from Belarus National University with a digipeater amateur radio payload and student experiments. A final cubesat reported to have been deployed on this mission is a mystery. Some reports suggested it was Hongyan-1, a China Academy of Space Technology LEO communications platform, but this has not been confirmed. Ibuki-2 ------- On Oct 29 JAXA launched H-IIA flight F40 from Tanegashima. The main payload was GOSAT-2, the second Greenhouse Gases Observating Satellite, also called Ibuki-2. The 1750 kg satellite - built by Mitsubishi Electric (MELCO) - carries the FTS-2 Fourier transform spectrometer and the CAI-2 Cloud and Aerosol Imager instruments which observe from the ultraviolet out to 16 microns in the infrared. The H2A second stage made a single burn to a 590 x 595 km orbit and deployed Ibuki-2, then ejected the Ibuki-2 payload adapter and the two-piece lower fairing. This exposed the lower payload deck, whose satellites were deployed into the same orbit. The largest secondary payload was the 330 kg Khalifasat, an imaging satellite built by the Emirates' Rashid Space Centre in Dubai. It is a followon to the Dubaisat 1 and 2 satellites launched in 2009 and 2013, which were developed with South Korean help. Diwata 2 is an imaging satellite developed by the Phillippines Dept of Science and Technology with a mass of 56 kg. Ten-Koh, from Kyushu Institute of Technology, is the LEO Environments Observation Satellite, a 22 kg polyhedron design based on their earlier Shi'nen-2 probe. Aoi, or STARS-AO, is a 1U cubesat from Shizuoka University. The STARS series normally involves tether experiments but this mission features a 1-cm aperture low light camera for imaging star fields. AUTCube-2 is a 1U cubesat from the Aichi University of Technology. It has a bright LED which is intended to make the satellite visible to ground observers. This has the potential to annoy astronomers, since the orbit is roughly a noon-midnight SSO and thus will be seen on the ground during the middle of the night local time. However, it remains to be seen how bright the satellite will actually be. The H-2A second stage made a final depletion burn which changed its inclination from 97.8 deg to 98.9 deg. PROITERES 2, from the Osaka Institute of Technology, a 45 kg ion propulsion test satellite, was not part of the launch although it was initially expected to be and was included in the prelaunch press kit. Beidou 41 --------- Beidou Daohang Weixing 41 (Beidou Navigation Satellite 41) launched at 1557 UTC Nov 1 from Xichang on a Chang Zheng 3B to 197 x 35815 km x 28.5 deg geotransfer orbit. The CAST-built sat, first of its subtype, will enter GEO and become satellite G1Q of the Beidou-3 system. GLONASS-M 57 ------------ Another GLONASS navigation satellite was launched from Plesetsk on Nov 3 by Soyuz-2-1B/Fregat. This was the second successful Soyuz launch since the MS-10 failure. This satellite was expected to be code-named Kosmos-2529 after launch. Kepler and Dawn --------------- On Oct 30 NASA announced that the Kepler space telescope, out of propellant, is being retired. Kepler was launched in 2009 and has revolutionized our knowledge of exoplanets, showing that Earth-sized objects orbit most of the stars in the sky. Kepler is in an Earth-trailing solar orbit, currently about 68 degrees behind us in the vicinity of Earth-Sun L5. The same day, NASA's Dawn space probe, orbiting the dwarf planet (1) Ceres, fell silent as it too ran out of propellant. Dawn was launched in 2007 and was the first mission to use ion propulsion to visit multiple worlds. The probe orbited Vesta from Jul 2011 to Sep 2012, and Ceres from Mar 2015 onwards. Erratum -------- The intermediate transfer orbit apogee for AEHF 4 was 32578 km, not 22578 km. Apologies for the typo.
