On the 10th at 8:40pm the Pleiades is 8 degrees above the Moon.

Between the 10th - 14th Mars passes very close to the star Porrima (2.7 mag) in Libra. At 7:00pm on the 12th the star is barely ¼ of a degree left of Mars in the SE.

Venus is in close conjunction with Saturn on the 11th. At 5:00pm in the SW Saturn is just 2 degrees above right of Venus.

Mercury is in close conjunction with the the star Acrab (2.5mag) in Scorpius on the 11th. At 7:00am Mercury will be 2½ degrees above the horizon and at 126 degrees azimuth with Acrab less than ½ a degree to the lower left of it.

On the 12th at 11:00pm the Moon is midway between the Mu Geminorum (2.8 mag) and Zeta Tauri (2.9 mag). The star named “ Hip 28734” (4.1 mag) in is just 1½ degrees to the upper left of the Moon.

At 9:00pm on the 13th the star Mekbuda (4th mag) in Gemini is 3 degrees below the Moon. An of the bright star Mu Geminorum by the Moon occurs on the 13th. This will occur over USA and Canada.

The Geminids meteor shower reaches its peak on the 13th - 14th .

An uncrewed Boeing's CST-100 Starliner will launch atop a United Launch Alliance Atlas V rocket from Space Launch Complex 41. This is the first of two demonstration flights required to prove the space systems meet NASA’s requirements for certification to carry astronauts to and from the International Space Station.

On the 20th at 2:30am the Moon will be between the stars Delta Virginis (3.3 mag) and Porrima (2.7 mag). The Moon is just 2 degrees from Porrima.

News: It was announced on the 30th October that NASA is to send a golf-cart sized robot to the Moon. It's called the Volatiles Investigating Polar Exploration Rover (VIPER). There is potentially millions of gallons of water ice on the Moon which NASA wish to investigate further in the polar regions. Among the instruments is a metre long drill which will tap in into the ice over 100 days. NASA believes VIPER will help create the first global water resource maps of the Moon. VIPER will land on the Moon in December 2022, if all goes according to plan.

Facts: The Wilkinson Microwave Anisotropy Probe (WMAP) is a NASA Explorer mission that was launched on 30th June 2001 to make fundamental measurements of cosmology and studying our universe as a whole. From where WMAP was positioned at Lagrange 2 (1.5 million kilometers from Earth) thermally stabilizes it and minimizises the contaminating solar, terrestial and lunar emissions. It measured the entire sky every six months completing its first, full-sky observation in April 2002.
