Southern Sky News for 2009 August

Augustus is Jupiter se maand. Nie eens Mars wat so "groot" soos die maan gaan word, gaan die ou grootte se donder steel nie. Oops! Nou is almal weer ontsteld. Nee! Nee! Nee! Mars gaan nie so groot soos die maan word nie. Jupiter en sy mane is die hele Augustus-maand van vroeg tot laat sigbaar. Die mane is nou wel net sigbaar met `n kragtige verkyker of klein teleskoop. Op 14 Augustus is die Jupiter in opposisie as die aarde direk tussen hom en die son is. Dit is dan ook op sy helderste.

Bydrae deur Amateur Sterrekundiges...

Goeiedag Vriende

Sterrekunde is een van die min displines in die wetenskap waar amateurs nog belangrike bydraes kan maak - gaan kyk gerus op APOD by http://antwrp.gsfc.nasa.gov/apod/astropix.html na die belangrike ontdekking onlangs gemaak deur 'n amateur sterrekundige in Australië: 'n nuwe impak-letsel op Jupiter.

As jy nie by die link kan uitkom nie, hier is die foto wat geneem is van Jupiter, met die impak-letsel 'n swart merk net onderkant die boonste pool van die planeet.

Moenie die amateurs afskryf nie - word eerder een!!!!

Groete en "clear skies"!!

How do you sneeze in a spacesuit? 'Aim well,' astronaut tells YouTube questioner

By Mike Schneider, The Associated Press

CAPE CANAVERAL, Florida - When it comes to sneezing in a spacesuit while in the void of space, it is best to aim well.

That's the advice lead spacewalker David Wolf offered Tuesday while answering one of the questions posted on YouTube for the crew of the space shuttle Endeavor.

"I've done it quite a few times, most recently yesterday," said Wolf, who led the mission's second spacewalk Monday and was set to go on a third spacewalk Wednesday. "You learn in training, and I don't know how to say this, aim well. It can mess up your view and there is no way to clear it."

Land on the Moon in Google Earth

To celebrate the 40th anniversary of the Apollo 11 Moon landing, Google has launched a new feature: the Moon in Google Earth. You can now use Google Earth to explore, fly around and search the Moon. Google was able to get several astronauts to participate in this new feature, and you can get tours of landing sites, narrated by Apollo astronauts, view 3D models of landed spacecraft, zoom into 360-degree photos to see astronauts' footprints and watch rare TV footage of the Apollo missions. The hi-resolution views of the Moon were developed in collaboration with NASA Ames Research and JAXA. It's loads of fun and provides an historic perspective as well as a look to the future of lunar exploration. If you already have Google Earth 5.0 on your computer, just click on the tab on the top toolbar that has a picture of Saturn, and click on Moon. If you click on the Apollo 11 flag, you can zoom in on that location and take a tour of the first landing site on the Moon! What a great way celebrate the 40th anniversary. Enjoy!

Selfdoen: `n Sterwiel vir die fynproewer en die beginner..

Hier is `n selfdoenprojek vir sterkykers. Dit is `n sterwiel (Planisphere) vir die suidelike halfrond wat Auke Slotegraaf ontwerp het. Wat dit so `n uitsonderlike sterwiel maak is dat jy dit kan verander vir minder sterrre (ligbesoedelde gebiede) of meer sterre vir die fynproewer, of net die konstellasies, of die bekende inheemse sterre en sterpatrone eie aan die Suide.

Besoek Auke se blog: www.psychohistorian.org en laai die Pdf-lêer (1.7M) af. Maak vir jou uitdrukke: A3-grootte en op effens dikker pappier. Dit werk ook op A4-grootte. Lamineer die uitdrukke vir beskerming. Die instruksies is ingesluit.

NASA managers downplay ascent debris strikes

STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION

Updated after news conference

Running a month late because of hydrogen leaks and stormy weather, the shuttle Endeavour finally roared to life and blasted off Wednesday on its sixth try, rocketing away through a hazy sky toward a Friday rendezvous with the International Space Station.

Multiple pieces of foam insulation fell from the ship's external tank during the early moments of flight, but it was not immediately clear whether the shuttle's fragile heat shield suffered any significant damage.

Lightning checks delay shuttle's launch to Sunday

Already a month behind schedule, launch of the shuttle Endeavour on a 16-day space station assembly mission was delayed at least 24 hours, from Saturday to Sunday, to give engineers time to evaluate the effects of multiple lightning strikes at the launch pad during a severe thunderstorm Friday.
