隨著1969年阿波羅計畫(阿波羅11)成功登月後,至今50週年,人類持續對這個似乎瞭解卻又不熟的月球充滿夢想,最新的計畫是在月球建造人類基地,目的是探索太空,包括上火星。(https://www.nasa.gov/moon

以色列航太工業(Israel Aerospace Industries (IAI))受到以色列非營利組織「SpaceIL」委託製造了登月艇「Beresheet」(希伯來原文是聖經創世紀「起初」的意思),目的地是月球上的「Mare Serenitatis region」。但重點是,這是個私人計畫,贏得「Google Lunar X Prize(https://lunar.xprize.org/prizes/google-lunar)」,不過因為到期而尚未實現而未獲得Google贊助,不過,計畫仍進行(如果成功登月還是有獎勵1百萬美元),通過募資後花費僅1億美元。

「SpaceIL」的創立者有Yariv Bash、Kfir Damari與 Yonatan Winetraub,資料來源:https://en.wikipedia.org/wiki/SpaceILhttp://www.visit.spaceil.com/founders



在2/21/2019,「Beresheet」成功地以SpaceX火箭「SpaceX Falcon 9」發射,在4/4/2019進入月球軌道,並預備在一個星期內登上月球表面,卻不幸地在4/11/2019預備登月時因為主引擎故障而墜毀(Google這時仍同意贊助獎勵金)。



之後,將持續第二次登月計畫「Beresheet 2」,並且已經開始獲得贊助。

已經提出第二次登月計畫了。

這張圖(截自https://www.bbc.com/news/science-environment-47879538)顯示成功登月的國家與月球表面位置,最多為美國,其次是再次登月機會不大的蘇聯,中國慢慢跟上,印度一天前成功登月一次,唯一在月球背面登陸成功的是中國「嫦娥四號」。



這裡是專利部落格,總是要找個與專利有關的資訊,以「SpaceIL」為專利權人來看,並未搜尋到任何專利,以「Israel Aerospace Industries」來找,檢索條件moon; landing; AssigneeIsrael Aerospace Industries; CountryIL, WO, US, EP; StatusGRANT。

看到一件與垂直起降飛機有關的專利:US9932118


1. A hybrid vertical take-off and landing aircraft comprising:
an engine;
a generator configured to produce electric power using power supplied by the engine;
a battery configured to store the electric power produced by the generator;
a motor configured to receive at least one of the electric power stored in the battery and electric power produced by the generator but not stored in the battery and provide the power to at least one thrust generating apparatus; and
a controller configured to select either silence mode or normal mode, and determine the amount of electric power stored in the battery and the amount of electric power not stored in the battery from the electric power supplied to the motor, based on the selected mode,
wherein, in the silence mode, the controller configured to supply only the electric power stored in the battery to the motor, and control a duration by adjusting output power of motor, and
wherein, in the normal mode, the controller configured to supply electric power not stored in the battery to the motor.


另外,從「SpaceIL」網站內容得知無線通訊部門主管Gadi Shirazi擁有29件專利的資訊。

從專利資料庫來看,Gadi Shirazi來自Motorola,從Google Patents確實得出29件專利的搜尋結果(inventor:(Gadi Shirazi) status:GRANT)。

隨意列舉一件:US5710568,關於天線:



1. An underground antenna comprising:
a generally elongate and planar radiating part having a free end, a ground connection remote from the free end and a feed connection between the free end and the ground connection and connected to radio electronic circuitry having a given impedance and wherein the elongate radiating part comprises an elongate portion extending between the feed connection and the free end, which is dimensioned for impedance matching with the given impedance; and
a reflective plane juxtaposed and generally parallel to the elongate radiating pan with the plane of the radiating part being generally perpendicular to the reflective plane, the ground connection being mounted on the reflective plane, thereby providing electrical ground connection and mechanical support to the elongate radiating part.
