RadFxSat (Fox-1B) Launched, Designated AMSAT-OSCAR 91 (AO-91)

AMSAT News Service Bulletin 322.01

DATE November 18, 2017
To All RADIO AMATEURS

RadFxSat (Fox-1B) Launched, Designated AMSAT-OSCAR 91 (AO-91)

The Delta II rocket carrying RadFxSat (Fox-1B) launched at 09:47:36
UTC on November 18, 2017 from Vandenberg Air Force Base, California.

Following a picture-perfect launch, RadFxSat was deployed at 11:09
UTC. Then the wait began. At 12:12 UTC, the AMSAT Engineering team,
watching ZR6AIC’s WebSDR waterfall, saw the characteristic “Fox Tail”
of the Fox-1 series FM transmitter, confirming that the satellite was
alive and transmitting over South Africa. Shortly after 12:34 UTC, the
first telemetry was received and uploaded to AMSAT servers by Maurizio
Balducci, IV3RYQ, in Cervignano del Friuli, Italy. Initial telemetry
confirmed that the satellite was healthy.

After confirmation of signal reception, OSCAR Number Administrator
Bill Tynan, W3XO, sent an email to the AMSAT Board of Directors
designating the satellite AMSAT-OSCAR 91 (AO-91). Bill’s email stated:

“RadFxSat (Fox-1B) was launched successfully at 09:47 UTC today
November 18, 2017 from Vandenberg Air Force Base in California and has
been received by several amateur stations.

RadFxSat (Fox-1B), a 1U CubeSat, is a joint mission of AMSAT and the
Institute for Space and Defense Electronics at Vanderbilt University.
The Vanderbilt package is intended to measure the effects of radiation
on electronic components, including demonstration of an on-orbit
platform for space qualification of components as well as to validate
and improve computer models for predicting radiation tolerance
of semiconductors.

AMSAT constructed the remainder of the satellite including the
spaceframe, on-board computer and power system. The amateur radio
package is similar to that currently on orbit on AO-85 with an uplink
on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz.
Experiment telemetry will be downlinked via the DUV subaudible
telemetry stream, which can be decoded using the FoxTelem software.

RadFxSat (Fox-1B) was sent aloft as a secondary payload on the United
Launch Alliance (ULA) Delta II rocket that will transport the Joint
Polar Satellite System (JPSS)-1 mission. RadFxSat (Fox-1B) is one of
four CubeSats making up this NASA Educational Launch of Nanosatellites
(ELaNa) XIV mission, riding as secondary payloads aboard the JPSS-1
mission.

Since RadFxSat (Fox-1B) has met all of the qualifications necessary to
receive an OSCAR number, I, by the authority vested in me by the AMSAT
President, do hereby confer on this satellite the designation
AMSAT-OSCAR 91 or AO-91. I join amateur radio operators in the U.S.
and around the world in wishing AO-91 a long and successful life in
both its amateur and scientific missions.

I, along with the rest of the amateur community, congratulate all of
the volunteers who worked so diligently to construct, test and prepare
for launch the newest amateur radio satellite.

William A. (Bill) Tynan, W3XO
AMSAT-NA OSCAR Number Administrator”

AMSAT Engineering reminds stations that the satellite will not be
available for general use until the on-orbit checkouts are complete.
Please continue to submit telemetry to assist the Engineering team in
completing the commissioning process.

[ANS thanks Paul, N8HM, for the above information]

物理大師霍金認為火星男孩的確不是地球人,因為他說出的事超乎很多科學家想像。火星男孩現已是20歲的火星青年,他又提到拿破崙說過的東方雄獅正在甦醒,並直指就是中國!
火星男孩並指出過去沒人注意的埃及金字塔八千多粒穀子的秘密,原來五千年前埃及法老就知道中國將擔負起人類絕續的重責大任!

史上最大冰山 快與南極洲分家

史上最大冰山 快與南極洲分家

一塊巨大冰原即將與南極洲分家,這塊名為「拉森C冰架」的冰原,是南極洲第四大冰架,面積六千平方公里,相當於六分之一個台灣。「拉森C冰架」可能在幾天或幾周內脫離南極洲,成為史上最大斷裂脫離的冰山,一旦它解體漂移,可能對船隻構成威脅。「拉森C冰架」是南極洲東北岸大拉森冰架的一部分。美國有線電視新聞網(CNN)報導,根據歐洲太空總署,「拉森C冰架」目前冰裂的長度已延伸到兩百公里,換句話說,它與大拉森冰架的連接僅剩五公里。六月初時,還有十三公里。

里茲大學的安娜.霍格指出:「我們不確定會發生何事,它可能斷成碎片,或整體漂移後才解體。無論是整體或碎片,洋流可能將拖向北方,可能遠至福克蘭群島。果真如此,將對德雷克海峽的船隻造成危險。」

「拉森C冰架」不是第一個斷裂漂移的大冰山。過去卅年,「拉森A」和「拉森B」也脫離了大冰架。有學者認為冰架脫離是自然現象,也有人指出,氣候暖化影響南極,讓冰架加速崩解。

美國太空總署表示,「拉森C冰架」的分裂將帶動惡性循環,導致冰架更加脆弱。原本受到「拉森C冰架」保護的更深層的冰層,預期會變得更易於消融和解體,特別是隨著氣溫升高。而大冰架在失去它的支柱之一後,也將變得較不穩定。
