Jonathan's Space Report No. 765

Jonathan's Space Report
No. 765                                                      2019 Jun 2   Somerville, MA
---------------------------------------------------------------------------------------------

International Space Station
---------------------------

On May 1-2 the Canadarm-2 and Dextre arms were used to replace a failed Main Bus Switching
Unit on the ISS S0 truss. The failed MBSU supported the channel 3 solar arrays.
It was exchanged with an MBSU on External Stowage Platform 2. This replacement unit was originally
the channel 2 MBSU, which failed in 2017, was brought inside ISS, repaired, and replaced on ESP-2.
There are 7 MBSUs on ISS:

   Launch order   Launch year   Current role
   MBSU 1         2002          Failed, on ELC-2 since 2013
   MBSU 2         2002          Active as MBSU-3 since 2019
   MBSU 3         2002          Failed, on ESP-2 since 2019
   MBSU 4         2002          Active as MBSU-4 since 2002
   MBSU 5         2005          Active as MBSU-2 since 2017
   MBSU 6         2007          Active as MBSU-1 since 2012
   MBSU 7         2013          Spare on ESP-2 since 2013


On May 4 SpaceX launched Dragon CRS-17 towards the Station. The CRS-17 trunk carries
OCO-3, a carbon measuring experiment, and STP-H6, with a set of USAF Space Test Program
experiments. STP-H6's experiments include XCOM, an X-ray transmitter which will carry
out communications experiments using the ISS NICER X-ray observatory as a receiver -
giving a whole different meaning to "X-band".

Dragon arrived at ISS on May 6, with SSRMS grapple at 1101 UTC and
berthing on Harmony nadir at 1422 UTC.  On May 10-11 OCO-3 was installed
on site EFU3 of the Kibo Exposed Facility, and STP-H6 was installed on
site 3 of Express Logistics Carrier ELC-3. The CATS experiment, launched
in 2015, was removed from the Kibo EF and installed in Dragon's trunk
for disposal; the SCAN testbed, launched in 2012, was similarly removed
from the ELC-3 and stowed in the trunk.

A failed BCDU (battery charge-discharge unit), launched in 2006, was removed from
the P4 truss on Apr 3 and placed on ELC-1; on May 16 it was brought inside the Kibo
airlock.

On May 29 astronauts Ovchinin and Kononenko made a spacewalk, VKD-46, from the
Pirs module, using spacesuits Orlan MKS-4 and MKS-5. For this spacewalk, to celebrate
the 85th birthday of the first spacewalker on May 30, they wore backpacks decorated
with the slogans "Leonov Number 1" and "Happy Birthday Aleksey Arkhipovich" (in Russian,
of course).

They depressurized the airlock at about 1530 UTC and opened the hatch at 1542 UTC.
They installed a commemorative portrait of Leonov on the EVA ladder, retrieved
a decontamination towel left tied to a handrail by Yuriy Lonchakov in Dec 2008;
retrieved a thermal sensor boom, 'Test' exposure cassettes, the IMPAKT experiment
and Vinoslivost' panels, cleaned windows on the airlock module,
and disassembled the Obstanovka experiment. Two Obstanovka experiment boxes
and two mounting booms were jettisoned between 1945 and 2101 UTC.
The hatch was closed at 2143 UTC and the airlock was repressurized at 2148 UTC.

Electron
--------

On May 5 Rocket Lab launched Electron mission 6, nicknamed 'That's A Funny Looking Cactus'.
The payload was USAF Space Test Program mission STP-27RD, consisting of the 150 kg
Harbinger satellite and two cubesats.

Harbinger is a small imaging radar satellite built by York Space Systems (Denver)
and will carry out a mission for the US Army Space and Missile Defense Command.

SPARC-1 (Space Plug-and-Play Architecture Cubesat)  is a 6U mission from
the USAF Research Lab and the Swedish defense agency FMV, testing
advanced computing hardware in space.

The Falcon Orbital Debris Experiment (Falcon-ODE) 1U cubesat from the USAF Academy, will release
2cm and 4cm steel spheres to act as tracking targets.


Beidou DW45
-----------

The 45th Beidou satellite was  Beidou-2 G8, a replenishment satellite for the older Beidou phase 2
system. It was launched to geotransfer orbit on May 17.

RISAT-2B
--------

India's RISAT-2B radar imaging satellite was launched on May 22. It replaces the Israeli-built
RISAT-2, launched in 2009. Mass of RISAT-2B is 615 kg.

Yaogan-33
---------

The launch of China's Yaogan-33 radar satellite on May 23 was a failure.
The third stage burn was not performed successfully and the vehicle did
not reach orbit.


Starlink
--------

SpaceX launched its first batch of 60 Starlink Ku-band internet
satellites on May 24.  The Falcon 9 rocket placed the satellites in a
434 x 442 km x 53.0 deg. Each one is about 200-250 kg (the press kit
says 227 kg, but this is suspiciously close to the metric equivalent of
500 pounds, so it's possible they really mean 500+-50 lb = 227 +- 23
kg). The satellites are a flat panel with krypton-propellant electric
thrusters and a single deployable solar panel.

Observers in Europe saw the satellites as a spectacular string of mag 2
to 3 objects a few hours after launch. As of May 30 it appears the
satellites are mostly in the mag 4 to 7 range with frequent flares to
mag 2 and occasional brighter flares, depending on illumination
conditions and satellite orientation. (For the nonastronomers:
bigger mag is fainter, mag 1 = brightest stars in the sky and
mag 6 = barely naked-eye visible at a dark site).

The brightness of the satellites has raised concerns in the astronomical
community - a full constellation of many thousand satellites could
interfere with observations and, if they are brighter than mag 5 or so,
might dominate the naked-eye night sky in dark locations. However, it is
likely to take some weeks before we really understand how much of the
time the satellites are bright and whether it's a real problem. SpaceX
have now stated that they will look at ways to reduce the reflectivity
of later satellites.

In the meantime, the  60 satellites launched so far are fascinating to
watch, if you live somewhere less cloudy than Boston has been lately.

SpaceX report that 56 of the 60 satellites are working as expected,
and 4 have some problems but are in communication with the ground.
In addtion, there are a further 4 debris objects which tumble with
large observed brightness variations


Glonass
-------

Glonass-M No. 58 (Uragan-M No. 758) was launched on May 27, replenishing
the Russian navigation system. It will probably get the official cover name Kosmos-2534.

Yamal-601
---------

Yamal-601, a communications satellite for the Russian company Gazprom Space Systems built
by ISS Reshetnev, was launched on May 30 by a Proton from Baykonur into geotransfer
orbit.


Hayabusa-2
----------

Hayabusa-2 ejected a second small `target marker' onto the surface of Ryugu
at about 0219 UTC May 30, during another descent to about 10 metres above
the asteroid.

WGS 10
------

The USAF Wideband Global Satcom 10 satellite, launched on Mar 16 to a mildly
supersynchronous 462 x 44260 km x 27.0 deg transfer orbit, is using an unusual ascent
path to GEO. By Mar 26 its orbit was near-synchronous and equatorial but elliptical,
25876 x 45130 km x 0.2 deg. Since then it has slowly circularized and by May 30
its orbit was 34716 x 36850 km. This is in contrast to the usual practice of getting
one end of the ellipse to the GEO height quickly and only then adjusting the other.
The WGS 10 strategy may allow comms with a single ground station more quickly.

SSO-A
-----

Three more SSO-A cubesats have been identified: objects J, U and W are SPAWAR-CAL-O,
SPAWAR-CAL-R, and SPAWAR-CAL-OR. They are 1U cubesats for the US Navy Space and
Naval Warfare Systems Command (SPAWAR) used for calibration of space tracking systems
and carry optical and radar reflectors.


Erratum
-------

IOD-1 GEMS is owned by Satellite Applications Catapult Ltd., although
built by Orbital Microsystems and ClydeSpace. Catapult has a ground
station at Goonhilly in Cornwall, site of the first transatlantic satcom
link.

Table of Recent Suborbital Launches
-----------------------------------

Sandia National Labs launched two Terrier Malemute rockets with technology payloads in April,
according to T. Rummler from Sandia.

The Trident II test on May 9 sent its reentry vehicles into the South Atlantic Ocean off the
coast of Namibia.

The University of Southern California's student rocket group RPL flew a rocket called Traveler IV
to 103 km on Apr 21, a record apogee for a student built rocket.

Jonathan's Space Report
No. 764                                                        2019 Apr 30 Somerville, MA
---------------------------------------------------------------------------------------------

International Space Station
---------------------------

Correction to previous description of battery work: the new-but-failed battery
that was removed on Apr 3 was the one in channel 4A3 slot 5, not the one in slot 3.
On Apr 5 the SPDM moved NiH battery 0072 from AP005 on P4 IEA 4A slot 6 to slot 5.

On Apr 8 McClain and St-Jacques performed spacewalk EVA 54. The airlock was
depressurized by about 1125 UTC with hatch open at 1126 and the suits on battery
power at 1131. At  1229 the adapter plate removed from 4A slot 6 and placed on
top of the plate in slot 2 at 1240 UTC. This opens up slot 6 for one of the old
batteries.

The spacewalkers then carried out cabling to provide external wireless support and
backup power to Canadarm-2. The airlock was repressurized at 1800 UTC.

On Apr 11 the SPDM moved NiH battery 0069 from EP7 slot Y to the newly empty
slot 6 on P4 4A. Then, battery 0070 was moved from the Dextre EOTP to slot Y.

So the 4A side has the following right now:
     Slot 1  Li-ion 15?        Slot 2  Adapter 07 + Adapter 05
     Slot 3  Li-ion 17?        Slot 4  Adapter 06 + NiH 0071
     Slot 5  NiH 0072          Slot 6  NiH 0069

On Apr 17 the 10th Antares rocket took off from the Mid-Atlantic
Regional Spaceport at Wallops Island, placing Cygnus NG-11 (the S.S.
Roger Chaffee) in low orbit at 2053 UTC and separating from the payload
at 2055 UTC. The Chaffee reached the ISS on Apr 19, with SSRMS
grapple at 0928 UTC and berthing on Unity nadir at about 1130 UTC.

The NG-11 mission carries a large number of nanosatellites hosted on a
variety of dispenser systems.

Four Planetary Systems Corp. CSD 3U deployers were attached to the
Antares second stage, and ejected their payloads, SASSI2 and 12
ThinSats, at 2059 UTC Apr 17.  Unusually, the payloads were not
cataloged by US space tracking, and were expected to have reentered by
around Apr 24.


SASSI-2 (Student Aerothermal Spectrometer Satellite of Illinois and Indiana,
correctly written as SASSI-superscript-2) is a 3U cubesat from the University
of Illinois to study the diffuse bow shock of a satellite in low orbit.

The ThinSats are a new design from NearSpaceLaunch for the Virginia Commercial
Space Flight Authority and carry student experiments. Twelve Thinsats were
deployed. Each is made of a number of Thinsat cases 0.01 x 0.11 x 0.11m in size
connected by solar panel ribbons 0.30m long 0.05m wide. The satellites are
launched folded up and deploy after ejection in an accordion-like fashion.
The twelve satellites include:
 Three Thinsat 3T (1B,1G,1K), consisting of three Thinsat cases connected by two ribbons.
 Overall mass 1 kg, size 0.01 x 0.1 x 1.3m. 

 Six Thinsat 6T (1C,1D,1F,1H,1J,1L), consisting of six Thinsat cases connect by five ribbons.
 Overall mass 2 kg, size 0.01 x 0.1 x 2.7m

 Three Thinsat D+4T (1A, 1E, 1I), consisting of five Thinsat cases (one of them a double-width
 0.03 x 0.11 x 0.11m case) connected by 4 ribbons. Overall mass 2 kg, size (0.01-0.03) x 0.1 x 2.2m. 

The JAXA J-SSOD No. 11 dispenser will be delivered to the Kibo module for later deployment.
It contains three 1U cubesats developed by Kyushu Tech students:
 Uguisu, for Kyushu Tech
 Raavana-1, for the Arthur C. Clarke Institute for Modern Technologies, Moratuwa, Sri Lanka;
 Nepalisat-1, for the Nepal Academy of Space Technology, Kathmandu.

The Nanoracks NRCSD-16 payload will also be delivered to the Kibo module for later deployment.
It includes:
  Aeternitas (1U, Old Dominion University, Virginia);
  Libertas (1U, University of Virginia);
  Ceres  (1U, Virginia Polytechnic);
  KRAKsat (1U, Kraksat team and Akademia Gorniczo-Hutnicza, Krakow, Poland) with
   a ferrofluid attitude control system experiment.
  Swiatowid (2U, SatRevolution, Wroclaw, Poland), with a 4m res Earth imager.
  IOD-1 GEMS, Orbital Microsystems (Boulder, Colorado and Harwell, UK; 3U from ClydeSpace),
   with a passive microwave weather sensor.
  EntrySat (2U from Institut superieur de l'aeronautique et de l'espace, Toulouse), to study
   the atmospheric reentry environment.

The Nanoracks NRCSD-E mission 7 is attached to the Chaffee's service module.
Its payloads are:
  Aerocube-10a, a 1.5U cubesat from the Aerospace Corp containing
  29 small subsatellites (AC-10a Probe 01 to 29), each 0.016 kg and 0.1m in diameter,
  which will be ejected to serve as radar targets to study atmospheric density.
  AC-10a also has an optical beacon to serve as a target for AC-10b.

  Aerocube-10b, a 1.5U cubesat with a steam thruster, to carry out proximity
  manuevering near AC-10a.

  Seeker, a 3U cubesat from NASA JSC to serve as an inspector satellite maneuvering
  in the vicinity of the Chaffee.

  Kenobi, a 3U cubesat from NASA JSC which will remain attached to the NRCSD-E and
  will relay data from Seeker.

Finally, the SEOPS LLC Slingshot system will be attached to the Chaffee before it
departs ISS, and will deploy further cubesats whose identities have not yet been
revealed. These cubesats will be delivered to ISS on the next Dragon.


PSLV
-----

It has now been confirmed that the two NanoAvionics cubesats M6P and
BlueWalker-1 were ejected into the wrong orbit (435 x 514 km instead of
493 x 510 km), probably due to a deployment hang-up delaying the
ejection until after the final PSLV-PS4 burn.

Arabsat 6A
-----------

The Arabsat 6A communications satellite was launched by the first operational
Falcon Heavy on Apr 11. The two side cores landed back at Cape Canaveral
and the center core landed downrange on the OCISLY droneship. The second
stage carried on to parking orbit and then after a second burn
to highly elliptical supersynchronous transfer orbit of 324 x 90078 km x 23.0 deg
By Apr 26 the satellite was in a 36074 x 89938 km x 1.3 deg, ready to lower
apogee to GEO.

During the voyage back to port the core stage toppled over onto the deck
of the OCISLY and was partly destroyed.



B'reshit
--------

The SpaceIL lunar lander made several orbit circularization burns from Apr 4 to Apr 10.
On Apr 6 apogee was lowered from 10000 km to 750 km; on Apr 8 at 0548 UTC
the orbit was reduced to 211 x 467 km, and on Apr 10 about 1700 UTC to 16 x 200 km.
On Apr 11 at 1912 UTC B'reshit began its landing burn, but after failure
of an IMU the main engine cut off. It was restarted too late to save the landing,
with impact (possibly near 18E 32N) at 1923 UTC Apr 11.

Beidou
------

China launched a new Beidou 3 satellite on Apr 20 to geostationary transfer orbit.
It reportedly was planned to enter an inclined GEO at 55 degrees, with apogee
burn apparently on Apr 21, but as of Apr 30 the satellite had not been tracked
in its new orbit.

Tianhui-2 Group 1
-----------------

On Apr 29 China launched two new mapping satellites,  Tianhui-2 01 zu 01
xing and Tianhui-2 01 zu 02 xing, into a 0600 local time descending node
sun-synchronous orbit. The vehicle was launched at 2252 UTC and entered
orbit around 2305 UTC; After payload separation the third stage made a
perigee-lowering burn at 2311 UTC.

Hammaguir
---------

From 1952 to 1967, France's main space launch site was the CIEES (Centre
Interarmees d'Essais d'Engins Speciaux) B2 site at Hammaguir, Algeria.
(The older CIEES B0 and CIEES B1 were at Colomb-Bechar to the northeast,
and were used for small military missile tests). Until 2015, as far as I
can tell, no map of the CIEES B2 had been publicly available. The French
space agency CNES then released a 1965 map for the 2015 celebrations of
the anniversary of the first French satellite launch. Thanks to this,
which I just became aware of (courtesy of @syncloss on twitter),  it is
now possible to identify the locations of the launch pads at CIEES B2.

International Space Station
---------------------------

Soyuz MS-12 was launched on Mar 14 carrying Aleksey Ovchinin, Nick Hague and Christina
Koch. It docked with the Rassvet module at 0101:43 UTC Mar 15, beginning ISS Expedition 59.

Progress MS-10 made a 0.7m/s burn to adjust the ISS orbit at 1422 UTC Mar 23.

The new Li-ion batteries delivered by HTV-7 last September on the External Pallet EP7 are finally being installed
in a mixture of robotic (SSRMS/Dextre SPDM) operations and manual work on spacewalks.
EP7 is stored on the POA location on the Mobile Base System.

Here is the chronology of activities (most of you will want to skip this bit!)
  Mar 19       SPDM move NiH battery 0070 from P4 truss IEA 4A slot 3 to Dextre's EOTP3 stowage point.
               SPDM move NiH battery 0073 from P4 4A slot 1 to EP7 slot X for disposal
               SPDM move Li-ion battery 0006 from EP7 slot C to P4 4A slot 3
                      Unfortunately this battery failed on Mar 22.
  Mar 20       SPDM move NiH battery 0074 from P4 4A slot 5 to EP7 slot Z for disposal
               SPDM move NiH battery 0069 from P4 4A slot 6 to EP7 slot Y for disposal
               SPDM move Li-ion battery 0010 from EP7 slot B to P4 4A slot 5
               SPDM move Li-ion battery 0008 from EP7 slot A to P4 4A slot 1
  Mar 22 1155? Quest airlock depress, Anne McClain EV1 in EMU 3008, SAFER 13
                                      Nick Hague EV2 in EMU 3003, SAFER 15
         1158       Hatch open
         1351-1410  Hague move adapter plate 0005 from EP7 slot A to P4 4A slot 6
         1355-1452  McClain move adapter plate 0006 from EP7 slot B to P4 4A slot 4
         1430-1442  Move NiH battery 0072 from P4 4A slot 4 to adapter 0005 on slot 6
         1513-1526  Move NiH battery 0071 from P4 4A slot 2 to adapter 0006 on slot 4
         1623-1648  Move adapter plate 0007 from EP7 slot C to P4 4A slot 2
         1836       Hatch closed
         1840       Repressurized
  Mar 26       SPDM move NiH battery 0065 from P4 2A slot 1 to EP7 slot B for disposal
               SPDM move NiH battery 0066 from P4 2A slot 3 to EP7 slot A for disposal
  Mar 27       SPDM move NiH battery 0068 from P4 2A slot 5 to Dextre
               SPDM move Li-ion battery 0003 from EP7 slot D to P4 2A slot 1
               SPDM move Li-ion battery 0019 from EP7 slot E to P4 2A slot 5
               SPDM move Li-ion battery 0018 from EP7 slot F to P4 2A slot 3
  Mar 28       SPDM move NiH battery 0063 from P4 2A slot 6 to EP7 slot C? for disposal
               SPDM move NiH battery 0067 from P4 2A slot 4 to Dextre
  Mar 29 1137? Quest airlock depress, Nick Hague EV1 in EMU 3006, SAFER 13
                                      Christina Koch EV2 in EMU 3008, SAFER 15

         1310         Remove adapter plates 13 and 14 from EP7 slots E and F
         1330         Adapter plate 14 (F) installed on P4 2A slot 6
         1351         Adapter plate 13 (E) installed on P4 2A slot 4
         1419         NiH battery 0064 removed from P4 2A slot 2
         1455         NiH battery 0064 installed on adapter plate 13 in 2A slot 4.
         1514         Adapter plate 12 (D) removed from EP7 slot D
         1529         Adapter plate 12 (D) installed on P4 2A slot 2
         1821         Hatch closed
         1828         Airlock repressurized         
   Mar 30       SPDM move NiH battery 0067 from SPDM arm 1? to EP7 slot D?
                SPDM move NiH battery 0068 from SPDM arm 2? to EP7 slot E?
   I believe NiH battery 0070 is still on the SPDM EOTP.
   But I haven't seen any confirmation of this.

   On Apr 2, the spare BCDU (Battery Charge/Discharge Unit) which was
   launched as part of ELC-1's initial cargo in 2009
   was moved from ELC-1 to replace P4 IEA's 4A3 BCDU which is thought to have failed.
   On Apr 3, the new-but-failed Li-Ion battery 0006 was removed from P4 4A3 and returned
   to the EP7, possibly on slot F?

 With these changes, and a few more still to come, the 2A and 4A solar arrays on the
P4 truss are back in action using the new batteries.

The Progress MS-11 cargo ship was launched on Apr 4 and docked with the Pirs module
only 3h20 min after launch.


S5
--

The US Air Force Research Lab's S5 satellite appears to have separated from its
Nusantara Satu host satellite at about 1800 UTC on Mar 4. Part of the Beresheet probe's
adapter structure was jettisoned in the `GEO graveyard' first to allow S5 to emerge.

Orbits of the three GEO objects on Mar 8 were:
 44048  Nusantara Satu             35779 x 35791 km x 0.1 deg  GEO 145.9E
 44065  S5                         36053 x 36055 km x 0.1 deg  GEO 139.3E+3.3deg W/day
 44066  Beresheet adapter          36131 x 36170 km x 0.1 deg  GEO 133.2E+4.6deg W/day

ZX-6C
------

China launched the Zhongxing-6C satellite from Xichang on Mar 9. ZX-6C is a C-band
communications satellite using the DFH-4 bus. By Mar 19 the satellite was
on station in GEO at 129.9E.

WGS-10
------

The US Air Force communications satellite Wideband Global Satcom 10 was launched
on Mar 16 by a Delta 4 Medium from Cape Canaveral into a supersynchronous transfer
orbit. The Boeing-built spacecraft carries X- and Ka-band communications payloads
and has both bipropellant and electric propulsion systems.
  The orbital data for WGS satellites were declassified last year; it's nice to
see public TLE data flowing for the new satellite. By Mar 22 it was in
a 13246 x 45069 km x 5.3 deg orbit.

PRISMA
------

The Italian Space Agency's PRISMA imaging satellite was launched by an
Arianespace Vega on Mar 22. Its 0.21m aperture telescope has a
hyperspectral detector with high spectral resolution near infrared and
visible imaging.

Beresheet
---------

The SpaceIL Beresheet probe (I'm told "B'reshit" is a better
transliteration from the Hebrew) has made a further orbit raising burn
for translunar injection. The 60 second perigee burn at 1230 UTC Mar 19
raised apogee beyond the Moon to 405 000 km. It entered  an estimated
400 x 10000 km lunar orbit on Apr 4, with a 324m/s burn starting at 1418
UTC and lasting 350s.

Kicksat-2
---------

The Kicksat-2 cubesat, developed by Zac Manchester (Stanford U.) and
funded on Kickstarter, deployed at least some of its circa 104 Sprite
chipsats on Mar 19 at 0340 UTC, as the satellite orbited over the
eastern Pacific southwest of California. Cees Bassa detected radio
signals from some of the Sprites. There are no US satellite catalog
entries for them. Their area-to-mass ratio is rather high, so they are
strongly affected by drag, and Manchester reports that they are expected
to have reentered within a few days.


Microsat-R
----------

On Mar 27 India's Defense Research Development Organization (DRDO) launched the first PDV Mk II
antisatellite interceptor from Kalam Island. After a three minute flight the missile collided
with the 740 kg Microsat-R satellite in LEO. Microsat-R was in a 260 x 282 km x 96.6 deg orbit
at the time, travelling north over the Bay of Bengal; PDV-II flew south from Orissa to intercept
it. PDV-II is reported to be a three stage vehicle - two solid boost stages and a kill vehicle
with liquid-propellant terminal guidance thrusters.

As of Mar 31 US authorities were reporting over 250 debris pieces detected. On Apr 5, 57 of them
were publicly cataloged, 13 showing apogees over 1000 km.

PSLV-C45
--------

India launched PSLV-C45 from Sriharikota on Apr 1. This was the first launch of
the PSLV-QL variant which has 4 strapon boosters, and the first time the PS4
upper stage carried solar panels to support long-term in-orbit attached payloads.

The main payload was EMISAT, a signals intelligence satellite for the Indian
defense research agency DRDO.

Cubesats on PSLV-C45 include: BlueWalker 1, a test IoT data relay
satellite for Avellan Space Technology and Science of Midland, Texas
built by NanoAvionics of Vilnius, whose own test satellite, M6P, is also
aboard; Astrocast 0.2 is another IoT test satellite for Astrocast of
Lausanne.  Danu Pathfinder 1 is the third in the AISTECHSAT series of
ship tracking  satellites from AistechSpace of Barcelona. Four Lemur-2
satellites for SpireGlobal are aboard, and twenty Planet cubesats
in the improved Flock 4 series.

Preliminary data suggest that (1) the final burn of the PS4 stage
may have been retrograde instead of posigrade, leading to an elliptical
rather than circular final orbit and (2) two of the satellite deployments
inadvertently occured only after this burn, leaving them in the PS4's
orbit rather than the higher target one.


R3D2
----

RocketLab launched the fifth Electron on Mar 28, carrying the DARPA R3D2
 (Radio-frequency Risk Reduction Deployment Demonstration) satellite.
R3D2 is a  150 kg Northrop Grumman satellite with a 2.3m diameter
deployable lightweight antenna.

TL2-01
------

China launched the first of its second-generation tracking and data relay satellites on Mar 31.
Tianlian-2 sat 01  (Tianlian erhao 01 xing) is a CAST DFH-4. The TL2 series will replace the four
TL1 sats already in orbit:

    Satellite             Launch date    Current GEO Location           Location History
    Tianlian-1 01 xing    2008 Apr 25    Indian O. Backup   80E          77E (2008-2013); 80E (2013-2019)
    Tianlian-1 02 xing    2011 Jul 11    Pacific           167E         177E (2011-2013); 167E (2013-2016)
                                                                        171E (2016) 177E (2016-Jan 2019) 167E (2019)
    Tianlian-1 03 xing    2012 Jul 25    Africa             17E          17E (2012-2016); 20E (2016); 10.5E (2016-Jan 2019); 17E (2019)
    Tianlian-1 04 xing    2016 Nov 22    Indian Ocean       77E          77E (2016-2019)
    Tianlian-2 01 xing    2019 Mar 31     TBD

As of Apr 6, geotransfer orbit TLEs for TL2-01 had stopped on Apr 1; this suggests it made an
apogee maneuver on that date but has not yet been located by US tracking in GEO. TL2-01's
apogee at 0800 UTC Apr 1 was at around 114E.


O3B
----

The final four satellites in the first-generation SES O3b constellation were launched
from French Guiana on Apr 4 on a Soyuz/Fregat to medium equatorial Earth orbit. The O3b satellites
provide broadband internet to developing countries.

Hayabusa-2
-----------

At 0400 UTC on Apr 4 Haybusa 2 began another descent from its 20 km home
point towards the surface of Ryugu. At an altitude of 500m, at 0156 UTC
Apr 5, it ejected the SCI (Small Carry-On Impactor), a 14 kg vehicle
with a 5 kg explosive shaped charge and a 2 kg copper mass. Hayabusa-2
then performed an avoidance burn to head off several km to the side of
the asteroid, over the horizon from the SCI location. Early in this
retreat, at 0214 UTC, it ejected the DCAM-3 camera package. At 0236 UTC
the SCI detonated, propelling the copper payload into the asteroid with
the intention of creating a new crater. DCAM-3 imaged this operation and
relayed the data to the main spacecraft. Hayabusa-2 will image Ryugu
from a safe distance and search for the resulting crater, before
returning to its 20 km home point on around Apr 20. The plan is to then
make a further descent to sample the freshly exposed material in the new
crater.


Erratum
-------
In JSR 760 I said that Progress MS-10 did a reboost on Dec 2; this should have read Dec 27
(with further reboosts Jan 18 and Feb 26).
