А как стрелки переводят!  :evil:  :

The importance of NRO's space ocean surveillance role in connection with the Navy and Coast Guard has been elevated since the Sept. 11, 2001 terrorist attacks. The need to track thousands of civilian ships worldwide has intensified, given the potential for seemingly harmless shipping to be involved in nuclear, chemical or biological terrorist operations.

Видно, прочитав эту статью, они добавили NOSS 3-4A и NOSS 3-4B под NROL-30 в план запусков.

Pyxis - это созвездие Компас

А может парусник на эмблеме указывает на назначение выводимых аппаратов? NOSS???

[carlos]

Несколько смущает то, что ранее в эмблемах НОССов-3 четко отражалась дуальность запуска (т.е. делался упор на наличие 2-х ПН)... Весы, Близнецы, Малый Пес...

А знак компаса?

[carlos]

В принципе, логично... Стрелка-то о двух концах...

Подождем. Осталось 2 дня.

NROL-30 will launch NOSS 3-4 (the 4th pair of 3rd generation NOSS satellites),
aboard an Atlas 5-401 vehicle, from Cape Canaveral, on 2007 Jun 14, during the
period between 13:00 to 16:00 UTC.

I suspect that the target plane is close to that of NOSS 2-3 (96029C, D and E).
Assuming that the 96029 plane is targeted exactly, and the same ascent
trajectory as NOSS 3-3 (05004A and C), which launched from CCAFS aboard an Atlas
3B-SEC, then lift-off would occur near 15:10 UTC, and this would be the orbit of
the leading payload at the first ascending node:

1 70001U          07165.69972605  .00000011  00000-0  20000-4 0    02
2 70001  63.4420  43.4101 0107863 182.7436 177.3009 13.39714521    01

The second payload would trail behind by a short distance. The Centaur stage may
be in a roughly similar orbit.

In reality, the target plane is likely to be a few degrees either side of the
96029 plane, and the ascent trajectory is likely to be different from than that
of NOSS 3-3, due to the change of launch vehicle; therefore, there will be at
least several degrees uncertainty in the orbital plane.

The following is a rough guide to visibility; prospective observers should make
their own evaluation, using the above elements.

Northern hemisphere observers well south of about 55 N, will have evening
visibility. At my latitude, near 44 N, passes will be low in the west, near
twilight. The situation improves considerably at more southerly latitudes, say
30 N.

Southern hemisphere observers well south of about 20 S will have morning
visibility.

I will revise the elements once the time of lift-off is known.

Это мы сможем проверить только после запуска.

Наклонение 63° уже сомнений не вызывает.

The official launch time has been announced: 2007 June 14, at 15:18 UTC:

http://www.spaceflightnow.com/atlas/av009/status.html

Here are revised search elements for the lead object, at the first ascending
node after orbital insertion:

1 70001U          07165.70528159  .00000011  00000-0  20000-4 0    05
2 70001  63.4420  45.4156 0107863 182.7436 177.3009 13.39714521    03

The plane would be about 2 deg east of the NOSS 2-3 (96029C, D and E) plane;
however, I note that the previous NOSS launch, from the same launch site, but
using a different launch vehicle, targeted a plane 1 deg west of the NOSS 2-2
(91076C, D and E) plane. I cannot exclude the possibility that the upcoming
launch will steer into the same position relative the 96029 plane, in which
case, the above RAAN (right-ascension of the ascending node) would be about 3
deg too high. Of course, other planes are possible, so I recommend allowing for
plus and minus several degrees uncertainty.

Visibility windows remain substantially the same as described in my earlier
message.

In the event of a launch delay, the launch time will arrive 14 min/day earlier.

1507 GMT (11:07 a.m. EDT)

Range is "go" for launch. The earlier troubles have been resolved.

1504 GMT (11:04 a.m. EDT)

T-minus 4 minutes and holding. The countdown has entered the planned 10-minute hold to give the launch team a chance to review all systems before pressing ahead with liftoff.
