Jonathan's Space Report 
No. 748 draft                                                 2018 Apr  2  Somerville, MA

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

Expedition 55 continues with  Anton Shkaplerov in command, Scott Tingle,
Norishige Kanai, Oleg Artemev, Ricky Arnold and Drew Feustel as flight
engineers.  Ferry ships Soyuz MS-07 and Soyuz MS-08 are docked to the
station.

Dragon CRS-14 arrived at the ISS on Apr 4. Canadarm-2 grappled it at 1040 UTC and
berthed it at Harmony nadir at 1300 UTC. 

On Apr 6-8 the Canadarm-2 and Dextre robot arms removed the PFCS (Pump
Flow Control System) and MISSE-FF payloads from the Dragon trunk.
MISSE-FF was installed on Express Logistics Carrier 2; the DCSU-2 spare
unit was temporarily removed to provide easier access to the install
location and reinstalled afterwards. On Apr 11 the Canadarm-2 was used
to remove the old PFCS (PFCS 3) from the P6 truss segment; it was later
moved to Dragon's trunk for disposal. There were four PFCS on P6, all
there since P6 was launched in 2000. In May 2013 during US EVA-21
astronauts moved malfunctioning PFCS 3 from the channel 2B slot and put
it in a spare slot, replacinging it with PFCS 1, which had been part of
the old EATCS thermal control system. The new PFCS, which I label PFCS
12, went in PFCS 3's old storage slot. 

Also aboard the Dragon, as well as RemoveDebris discussed in the last
issue, was a Japanese Small Satellite Orbital Deployer (J-SSOD) carrying
three cubesats: 1KUNS-PF, a 1U cube for the University of Nairobi,
Kenya; the 3U UBAKUSAT for Istanbul Technical  University, Turkey; and
the 1U Irazu from Tecnologico de Costa Rica. They will be deployed from
the Kibo module at a later date.

TESS
----

The Transiting Exoplanet Survey Satellite (TESS), an astronomical observatory
in NASA's Explorer program, was launched on Apr 18 by Falcon 9.
TESS will survey the sky to find exoplanets transiting bright stars
and nearby stars.


Arianespace
------------

Flight VA242 (launch vehicle L5102) successfully delivered two
communications satellites to low-inclination geotransfer orbit on Apr 5.
Hylas 4 for Avanti Communications is an Orbital ATK Geostar-3 and will
provide Ka-band broadband coverage for Europe and Africa. The DSN-1
satellite, built by Mitsubishi Electric for Sky Perfect JSAT, carries
the Kirameki-1/DSN-1 military X-band communications payload operated by
DSN Corporation on behalf of the Japanese armed forces and Sky Perfect
JSAT's Superbird-8 Ku-band commercial television payload.

Yaogan 31
---------

On Apr 10 China launched the YG-31 Group 1 mission. Satellites Yaogan
Weixing 31 hao 01 zu 01, 02 and 03 xing (which can be rendered as
YG-31-01 Sat 1, 2 and 3) were launched to an 1100 km orbit similar to
the Yaogan-9 series.

IRNSS-1I
--------

ISRO launched the Indian Regional Navigation Satellite Systems's IRNSS-1I satellite to transfer
orbit on Apr 11. The successful launch follows the failure of IRNSS-1H after a fairing separation
failure during launch last year; it was left in a 6500 km apogee orbit which has now decayed
to 4500 km.

Kosmos-2526
-----------

The Russian Defense Ministry's second Blagovest communications satellite, Blagovest No. 12L,
was launched on Apr 19. It will be given the cover name Kosmos-2526.


X-37B
-----

The OTV-5 mission launched in Sep 2017 has finally been located in orbit by hobbyists.
Orbit is 355 x 356 km x 54.5 deg - a higher orbit inclination than earlier X-37B missions.

Erratum:
--------

MISSE-FF is owned by Alpha Space of Houston, not Astra LLC.
