尋找外星生命 NASA宣布2069年星際任務

尋找外星生命 NASA宣布2069年星際任務

2017-12-21 01:16中央社 華盛頓20日綜合外電報導

美國國家航空暨太空總署(NASA)計畫展開一連串星際任務,尋找太陽系外的外星生命。

英國「鏡報」(Mirror)報導,NASA計畫於2069年,也就是人類首度登月100週年時,發射一艘機器人太空船,到鄰近的半人馬座南門二(Alpha Centauri)星系

距離地球「僅」24兆9000億英里的南門二是個三合星系統,由半人馬座α星A、半人馬座α星B及又稱比鄰星(Proxima Centauri)的半人馬座α星C組成。

天文學家認為,「幾乎可以肯定」的是,在南門二星系裡的類地小行星,可支持外星生命生存。

但要抵達南門二,太空船的速度至少必須達到光速的10%,即每秒鐘將近3000萬公尺。

即便能跨越這道門檻,這趟旅程仍需耗費44年,意味這艘太空船要到2113年才能抵達南門二。

任職NASA噴射推進實驗室(Jet Propulsion Laboratory)的弗利曼(Anthony Freeman)告訴「新科學家雜誌」(New Scientist):「這非常模糊。」

NASA據說也計畫探討不同選項,包括出動雷射驅動的微小探測器。這些探測器理論上可達1/4光速。

根據報導,NASA列入考量的其他技術包括藉由核反應或物質與反物質碰撞。

截至目前,人類僅製造出一艘成功離開太陽系的太空船,就是1977年發射的旅行家一號(Voyager 1)。

Satellite Activity From Azores Islands on Christmas

Pedro, CU2ZG says he will be active on satellites from grid square
HM58 on Christmas.

His equipment will include an Alaskan Arrow antenna, Yaesu FT-817ND,
Yaesu FT-857D, Kenwood  TS-2000 and a Wouxun KG-UV9DPlus. Most of
the operation will be done  using the TS-2000.

Expected operating days are December 23 and 24, plus December 25
during the afternoon/evening hours. Pedro says this will be a family
holiday and skeds will be accepted depending on his availability.
His exact location will be HM58qm, at the CU7BC QTH (check QRZ.com)
Watch his twitter account (@pdsousa) for updates.

December 20 Launch for HA-1 CubeSat with FM transponder and SSTV

The IARU has announced frequency coordination has been completed for
HA-1, a 2U CubeSat developed by the Teenagers Amateur Radio Center of
Activity in Huaian, China. HA-1 is planned for launch on December 20.

HA-1 will be mainly used for teenagers in Huaian to carry out
activities
related with amateur radio and aerospace science education. The
cubesat
is equipped with amateur radio repeater and SSTV(Slow Scan Television)
component, which is to validate still image transmission in narrowband
voice channel.

There is an SSTV beacon, which puts Date/Time/Location
information/temp-
erature etc on a SSTV picture. Amateurs worldwide can also use HA-1 to
test SSTV via the cubesat.

Uplink:    145.930 MHz FM
Downlink:  436.950 MHz FM
Telemetry: 437.350 MHz 9k6 BPSK

[ANS thanks the IARU for the above information]

Information for Requesting UT1FG/MM QSL Cards

John, K8YSE, posted a message on the amsat-bb on behalf of Yuri,
UT1FG/MM currently at sea aboard the MV Seahorse, “Yuri has asked
that anyone who has not received confirmations from this year and
previous year’s operations to prepare logsheets so that he can mail
them out when he arrives in New Orleans.”

John has posted an Excel Spreadsheet for you to enter your log data
plus an example of a completed log sheet at:
http://www.papays.com/sat/ut1fgqsl.html

John’s web page includes instructions to prepare your logsheet of
QSO’s
that Yuri can print, verify, sign and mail from one of his destination
ports. E-mail your logsheet to John at the address he lists in his
instructions. John will send an acknowledgement email when he receives
your request. This way you will know that Yuri will have your
logsheet.

Marinetraffic.com anticipates a December 15-16 arrival in New Orleans.
John requests you send your logsheet QSL request as soon as possible
so Yuri will have time to get them ready for mailing.

Yuri’s current ship, Seahorse, is a relatively new ship and is wider
than previous vessels he has captained so it cannot go through the
locks in the Great Lakes. On this voyage he will be more restricted
as to possible destinations than he was last season.

John concluded, “Yuri has been very busy with his duties and has
had little time for anything else. He sends his regards to all.”

Two-Part Video Demonstration Working AO-91 from Down Under

Peter Parker, VK3YE, has published two excellent introduction to
amateur satellites videos. Note that some of the QSO customs shown
are a little different than the common practice in Europe and North
America, but the tips are still generally applicable.

Peter, VK3YE, describes his two-part video demonstration as,
“A new amateur satellite has just gone up and it’s super easy to
work. You just need a pair of handhelds on 2m & 70cm FM.  Watch
this video to find out how to make contacts through AO91 with
equipment you probably already have.”

KG5CCI and F4DXV 7,634.775 km QSO Sets New Distance Record on FO-29

David Swanson, KG5CCI, and Jerome Lecuyer, F4DXV completed a
7,634.775 km QSO on December 12 via FO-29. This eclipses their
previous record on that satellite by 26.62 km and greatly
exceeds the theoretical maximum range of the satellite,
which is calculated at 7,502 km. Video of the QSO as recorded
by F4DXV can be viewed at:
