Jonathan's Space Report 
No. 702 draft                                          2014 Sep 6  Somerville, MA

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

The NanoRacks cubesat deployer package remains attached to the JEM RMS robot arm
while troubleshooting continues on electrical problems with the deployer.
Four more 3U cubesats remain in the deployers while another package of 8 deployers
with 16 x 3U equivialent of cubesats sits inside Kibo.

On Sep 10 at 2301 UTC Skvortsov, Artemev and Swanson undocked from the Poisk module
in Soyuz TMA-12M. The deorbit burn at 0130 UTC Sep 11 lowered the orbit to about
-22 x 418 km followed by module separation at 0158 UTC, atmosphere entry at 0201UTC
and landing in Kazakhstan at 0223 UTC.

Expedition 41 began with undocking of Soyuz TMA-12M with commander Max Suraev and
flight engineers FE-5 Reid Wiseman and FE-6 Alex Gerst.

Kobal't
-------

It now appears that something went wrong with the recovery of a Russian Defense Ministry
Kobal't spy satellite on Sep 2. (The satellite is usually called Kosmos-2495 in the press,
although the confusion about Kosmos numbering means it may actually be Kosmos-2493).

Based on the knowledge that the satellite was no longer in orbit of Sep 2, I calculated
(using algorithms pioneered by Phil Clark) that if it landed in the usual area,
the deorbit would have been northbound over the Horn of Africa around 1805 UTC Sep 2
with entry around 1818 UTC and landing around 1828 UTC near Orenburg in Russia.
The descent module (SA) would separate from the service module (AO) after the deorbit
burn, with the AO burning up since it does not have a heat shield. The AO carries
the solar panels, which are likely to break off early in the descent.

Reentering debris overhead was observed by people in Kazakhstan at
around 1814 UTC Sep 2, exactly the expected time for the service module
entry. (but also close to a pass of the Chinese Yaogan 5 satellite
wich completed its reentry two orbits later. However, Ted Molczan reports that
he has ruled out Yaogan 5 as a possibility.)

In addition, large amounts of reentering debris were observed
northbound over Colorado and Wyoming at about 0430 UTC on Sep 3, which
is consistent with the projected path and timing of the satellite if no
deorbit burn was made.

The most likely interpretation is that a deorbit attempt on a southbound 0330 UTC
pass over Russia was partly unsuccessful, causing the satellite to enter a low perigee orbit
leading to its unplanned demise over US territory. It is possible that the
SA landed successfully but the AO bounced off the atmosphere and remained in a very low
orbit for 7 further revolutions before finally succumbing over US territory.

Meanwhile, Bob Christy reports that NOTAMS (announcements of airspace
closures) suggest recovery dates for the two small SpK capsules. Based
on these I infer SpK landing times of Jun 20 0808 UTC and Jul 3 0402
UTC.


Asiasat 6
---------

On Sep 7 SpaceX launched the Asiasat 6 satellite. It reached a 175 x 202 km x 27.7 deg
parking orbit and then was delivered to a 154 x 35752 km x 25.4 deg geostationary
transfer orbit. Asiasat is a Hong Kong based telecom company.

Yaogan 21
---------

China's Yaogan 21 imaging satellite was launched to a 475 km, 1030LTDN SSO on Sep 8.
The mission continues a series begun with the Zi Yuan 2 satellites.

A small 67 kg subsatellite, Tiantuo-2 was also deployed. The Tiantuo
satellites are built by the National University for Defense Technology;
this one carries video imaging experiments.

Ariane 5
--------

Ariane 5 flight VA218, vehicle 573, placed two communications satellites in
geostationary transfer orbit on Sep 11.

Suborbital missions
-------------------

Russia launched a submarine missile on Sep 10; India carried out a training launch
of its Agni I missile on Sep 11. Three Trident missiles were launched from off the
coast of Southern California Sep 12, from an unidentified Trident submarine;
at least one of the launches was widely observed along the US west coast.
