Pa uopšte nije loše, gledajući uslove i opremu. :doubleup:

Pre dve godine na Tari jedno veče krene promena vremena. Poče da duva vetar, nebo se razbistri. Pa još pun mesec.
Nama labilnima to baš i ne prija, znate ono glavobolja, nesanica itd.
I izađem ja napolje. Odem 50 metara od kuće u mrak i pogledam u nebo. Božanstveno!!!

Gledamo filmove, igramo igrice a imamo besplatnu predstavu nad glavama. :)

Slazem se, pogotovu za ovo zadnje.



Imam stellarium na laptopu, pre njega sam koristio google sky maps na telefonu.

Planiram ponovo da krenem aktivnije da slikam, pauzirao sam zadnjih mesec dana.

NASA je objavila da je Juno uspešno izvršila svoj prvi od 36 planiranih orbitalnih preleta pored Jupitera.
Prelet je bio na najmanjoj distanci do sada (za bilo koju svemirsku letelicu koju je čovek poslao u istraživanje Jupitera), na svega ~4200 km. iznad površine oblaka Jupitera.
Svi naučni instrumenti za snimanje raznih parametara Jupitera, su uspešno radili sve vreme. Ono što nas (obične ljude) interesuje - jesu snimci u vidljivom delu spektra tj. fotografije Jupitera, a oni će biti objavljeni u narednim nedeljama, ovisno o tome kako budu bili obrađivani.


NASA's Juno mission successfully executed its first of 36 orbital flybys of Jupiter today.

The time of closest approach with the gas-giant world was 6:44 a.m. PDT (9:44 a.m. EDT, 13:44 UTC) when Juno passed about 2,600 miles (4,200 kilometers) above Jupiter's swirling clouds. At the time, Juno was traveling at 130,000 mph (208,000 kilometers per hour) with respect to the planet. This flyby was the closest Juno will get to Jupiter during its prime mission.

"Early post-flyby telemetry indicates that everything worked as planned and Juno is firing on all cylinders," said Rick Nybakken, Juno project manager at NASA's Jet Propulsion Laboratory in Pasadena, California.

There are 35 more close flybys of Jupiter planned during Juno's mission (scheduled to end in February 2018). The August 27 flyby was the first time Juno had its entire suite of science instruments activated and looking at the giant planet as the spacecraft zoomed past.

"We are getting some intriguing early data returns as we speak," said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "It will take days for all the science data collected during the flyby to be downlinked and even more to begin to comprehend what Juno and Jupiter are trying to tell us."

While results from the spacecraft's suite of instruments will be released down the road, a handful of images from Juno's visible light imager -- JunoCam -- are expected to be released the next couple of weeks. Those images will include the highest-resolution views of the Jovian atmosphere and the first glimpse of Jupiter's north and south poles.

"We are in an orbit nobody has ever been in before, and these images give us a whole new perspective on this gas-giant world," said Bolton.

The Juno spacecraft launched on Aug. 5, 2011, from Cape Canaveral, Florida, and arrived at Jupiter on July 4, 2016. JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate. Lockheed Martin Space Systems, Denver, built the spacecraft. Caltech in Pasadena, California, manages JPL for NASA.

Kakav su naslov smislili, pomislih da je misija propala. :besan: A završena je tačno kako je i planirano.

Pojavili su se prvi problemi. Ukratko: Juno je trebala 19. oktobra da upali motore i uspori-skrati svoju orbitu oko Jupitera, sa 53 na 14 dana. To se neće desiti pomenutog dana jer nešto nije u redu sa dva helijumska ventila (deo glavnog raketnog motora): umesto da se otvore za nekoliko sekundi (po dobijanju komande), njima je trebalo nekoliko minuta. NASA je kontaktirala proizvođača letelice, kompaniju Lokid Martin, i sada pokušavaju da ustanove šta se dešava.
Ovo znači da će i sledeća orbita Juno sonde, biti u dužini od 53 dana i da će se 11. decembra ponovo pružiti prilika za paljenjem motora za kočenje tj. skraćivanje trajanja orbite oko Jupitera. Ovo ne ugrožava osnovnu misiju letelice, osim što svako kruženje oko Jupitera traje duže od planiranog.

"Mission managers for NASA’s Juno mission to Jupiter have decided to postpone the upcoming burn of its main rocket motor originally scheduled for Oct. 19. This burn, called the period reduction maneuver (PRM), was to reduce Juno’s orbital period around Jupiter from 53.4 to 14 days. The decision was made in order to further study the performance of a set of valves that are part of the spacecraft’s fuel pressurization system. The period reduction maneuver was the final scheduled burn of Juno’s main engine.

"Telemetry indicates that two helium check valves that play an important role in the firing of the spacecraft’s main engine did not operate as expected during a command sequence that was initiated yesterday,” said Rick Nybakken, Juno project manager at NASA's Jet Propulsion Laboratory in Pasadena, California. “The valves should have opened in a few seconds, but it took several minutes. We need to better understand this issue before moving forward with a burn of the main engine.”

After consulting with Lockheed Martin Space Systems of Denver and NASA Headquarters, Washington, the project decided to delay the PRM maneuver at least one orbit. The most efficient time to perform such a burn is when the spacecraft is at the part of its orbit which is closest to the planet. The next opportunity for the burn would be during its close flyby of Jupiter on Dec. 11.

Mission designers had originally planned to limit the number of science instruments on during Juno’s Oct. 19 close flyby of Jupiter. Now, with the period reduction maneuver postponed, all of the spacecraft’s science instruments will be gathering data during the upcoming flyby.

“It is important to note that the orbital period does not affect the quality of the science that takes place during one of Juno’s close flybys of Jupiter,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. "The mission is very flexible that way. The data we collected during our first flyby on August 27th was a revelation, and I fully anticipate a similar result from Juno’s October 19th flyby.”


P.S.
Ono što ja mogu da primetim, je da kamera visoke rezolucije, kojom je trebalo fotografisati Jupiter (pre svega za javnost, a skoro nevažno za nauku), izgleda ne radi kako treba jer se slike nisu pojavile tj. ono malo što ima na NASA sajtu je vrlo slabo i snimljeno sa velike udaljenosti. Očito da i tu nešto ne štima.
