International Space Station

Expedition 49 continues.

The Nanoracks NRCSD-9 dispenser was extracted from Kibo's airlock on Sep 14
and eight Flock 2e-Prime cubesats for Planet were deployed. These were the final
payloads from a batch delivered aboard Cygnus OA-6.

On Oct 17 an Orbital ATK Cygnus cargo ship, the SS Alan Poindexter, was launched
on mission OA-5. The launch was the first flight of the Antares 230 rocket, featuring
a first stage with two Energomash RD-181 engines replacing the Kuznetsov/Aerojet AJ-26 engines used
on earlier Antares missions (which were implicated in the Oct 2014 Antares 130 failure),
and a second stage with the Castor 30XL solid motor. The Castor 30XL was on the previous
Antares launch but didn't get a chance to fire because of the first stage failure, so this
was its first real test. In the event the rocket performed above specification and
the mission reached a higher-than-planned 209 x 351 km orbit.

Cygnus OA-5 carries 2345 kg of pressurized cargo, and the external Nanoracks deployer
with four Spire Global Lemur-2 cubesats.

Oct 19 saw the launch of Soyuz MS-02 with astronauts Sergey Ryzhikov, Andrey Borisenko
and Shane Kimbrough.


The ESA Rosetta spacecraft, following close flyovers of the nucleus of comet 67P
in the 2 to 10 km range during September, made a deorbit burn at 2050 UTC Sep 29
and touched down on 67P/Churyumov-Gerasimenko at 1039 UTC Sep 30 at a velocity
of 0.9m/s. The spacecraft would have been unable to communicate from the nucleus
surface even if it had survived and the mission was declared complete after the
corresponding light travel time delay with loss of signal in Darmstadt at 1119 UTC.

Rosetta was launched on 2004 Mar 2 by Ariane L518 into a 0.88 x 1.09 AU
x 0.4 deg  solar orbit. It made a 1955 km Earth flyby on 2005 Mar 4, a
250 km Mars flyby on 2007 Feb 25, and a 5301 km Earth flyby on 2007 Nov
13 which left it in a 0.91 x 2.26 AU x 7.7 deg solar orbit. Following an
800 km flyby of asteroid (2867) Steins on 2008 Sep 5 and a 3162 km flyby
of (21) Lutetia on 2010 Jul 10, it made rendezvous with
67P/Churyumov-Gerasimenko on 2014 Aug  6 and ejected the Philae lander
from a range of 22 km on 2014 Nov 12.  Rosetta remained within 500 km of
the 67P nucleus following its rendezvous except for a far excursion
trajectory from 2015 Sep 23 to Oct 20 when it receded to a maximum
distance of 1490 km and an anti-sunward excursion from 2016 Mar 28 to
2016 Apr 3, at a maximum distance of around 1000 km. 


The ExoMars spacecraft entered the Martian gravitational Hill sphere
at 0110 UTC Oct 16, and at 1442 UTC Oct 16 split into the separate
TGO (Trace Gas Orbiter) and EDM (Entry-Descent-Landing Demonstrator Module)
vehicles. TGO made an insertion burn on Oct 19 from 1304 to 1523 UTC,
entering a 4-day-period, 346 x 95228 km x 9.7 orbit deg around Mars.

The EDM, named Schiaparelli, approached on a 62 x -13982 km x 8.2 deg
hyperbola and entered the Martian atmosphere at 1442 UTC at a speed
of 5.86 km/s and an angle of -11.9 degrees. 

During descent,  data was relayed to Mars orbiting spacecraft for later
retransmission as well as sent on a live link picked up by the GMRT
radio telescope near Pune, India.

Schiaparelli survived the entry and deployed its parachute 4 minutes
later at an altitude of 11 km. The heatshield was jettisoned 30 seconds
later, and at 1447 UTC the parachute and attached backshell were
separated at an altitude of 1.3 km over the Meridiani Planum landing
site at 6.11W 2.07S.

It now appears that the parachute/backshell separated 15 seconds earlier
than expected, for unknown reasons. Further, the thrusters fired
for only 3 seconds, and the lander transitioned to landing mode
while still well above the surface. A free fall of 19 seconds ensued,
followed by a high speed (hundreds of km/hr) impact.
At this point, unsurprisingly, communications from the lander ceased.

MRO has imaged the EDM lander's impact scar at 6.11W 2.07S. The
parachute appears to be 0.16km E 0.91km S of the lander.

Tiangong 2 and Shenzhou 11

China's second space laboratory was launched on Sep 15. Tiangong 2 has a mass
of 8600 km and was launched into a low perigee orbit by a CZ-2F rocket.
On Sep 16 at about 0904 UTC the lab raised its orbit from an initial 197 x 373 km
to 369 x 378 km x 42.8 deg; on Sep 26 the lab moved to a 381 x 389 km orbit.

The latest Chinese discussion of Tiangong 1 is more explicit than previous
reports in its confirmation that the old spacelab will reenter naturally
rather than be deorbited. Reentry will probably occur sometime in the second
half of 2017. Tiangong-1's current orbit is 358 x 380 km x 42.8 deg,
and its last orbit raising burn occurred on 2015 Dec 16.

On Oct 16 China launched Shenhzou 11 with astronauts Jing Haipeng and Chen Dong;
two days later, at 1924 UTC Oct 18, it docked with Tiangong-2 to begin what
is planned as a month-long mission.

On Oct 22 at 2331 UTC TG-2 ejected a 47 kg 'bansui weixing' (subsatellite) which
will remain in formation with TG-2 to image the complex.

Vega VV07

Arianespace's Vega rocket made its 7th flight from Kourou on Sep 16.
The AVUM upper stage made two burns to deploy TerraBella's SkySat 4 to 7
in a 500 km orbit at 0224 UTC, and then two further burns to put PeruSAT-1 in
a 677 km orbit at 0326 UTC. The AVUM made a final burn to deorbit itself
in the Indian Ocean west of Sumatra.


India's PSLV-C35 vehicle was launched on Sep 26 with a cluster of small satellites.
For the first time, the PS4 final stage made multiple burns to deliver payloads
to different orbits. Its first burn reached a 718 x 732 km orbit at 0358 UTC,
and ISRO's SCATSAT ocean wind speed scatterometer mission was deployed at 0359.
At 0504 and 0554 UTC two more burns reached a 661 x 704 km orbit and the DLA
dual launch adapter was ejected, followed by deployment of the remaining payloads:
  PRATHAM from IIT Bombay, with an ionospheric science instrument;
  PISAT from PES University, Bangalore, with an 80m resolution imager;
  CanX-7 from UTIAS/Toronto, with a deployable deorbit sail;
  Pathfinder 1 from Black Sky Global (Seattle) with a 1 meter imager;
  and three imaging satellites for the Algerian space agency ASAL:
    ALSAT-1B built by Surrey; ALSAT-2B built by Airbus/Toulouse; and ALSAT-1N,
     a cubesat built by Algerian engineers in Surrey and integrated in Algeria.


Intelsat's IS-33e communications satellite, a Boeing BSS-702MP model, has
suffered a failure of its main Leros apogee thruster in geotransfer orbit.
Orbit raising was delayed until late September; by Oct 18
the satellite was in a 31428 x 35927 km x 0.1 deg orbit.

Ariane L585
Ariane vehicle L585 was launched Oct 5 on mission VA231, placing
two communications sats in geotransfer orbit: Sky Muster II for
the Australian NBN broadcaster, and GSAT-18 for the Indian Space
Research Organization.


Communications with the STEREO-B science craft in solar orbit had been
lost on 2014 Oct 1 for unknown reasons; by 2016 it was assumed the
mission had been lost, but on Aug 21 the big DSS-14 dish at Goldstone
picked up a signal from it. This was great news for the heliophysics
community, but attempts to recover full communications with the tumbling
and underpowered spacecraft have met with mixed success, and as of Oct
11 recovery attempts were scaled back until STEREO-B drifts into a more
favorable attitude and orbital position.

Table of Recent Suborbital Launches

On Oct 5 Blue Origin flew the New Shepard rocket vehicle from the West Texas launch site to an apogee
of 93.7 km and landed it nearby 7min29s after launch. On this mission the New Shepard crew capsule,
which normally separates at apogee, instead fired its pusher abort motors 45 seconds after launch
at an altitude of 4.9 km, reaching an apogee of 7.0 km and landing 4min16s after launch. Before launch
it was expected that the in-flight abort separation of the capsule would destroy the booster rocket
but in the event the rocket's flight did not appear to be affected.
This was the 5th flight of New Shepard rocket vehicle 2, and possibly
the 6th flight of the first Crew Capsule.
