What's Happening in Space: November 2023

1^st November – Lucy mission: first asteroid flyby

Launched in 2021, NASA’s Lucy spacecraft will fly-by its first asteroid target - the small Main Belt asteroid Dinkinesh. The encounter on 1^st November will allow scientists to test its instruments in preparation for visits to multiple Trojan asteroids in the coming years. The main aim of the Lucy mission is to study the Jupiter Trojan asteroids which circle the Sun in the same orbit as Jupiter. This never-before-explored group of small space rocks orbit in two “swarms” that lead and follow Jupiter in its orbit. Asteroid Dinkinesh was added to Lucy’s list of targets at the start of this year and over its 12-year mission duration it will be the first of 10 asteroids that Lucy will visit. In 2025, before Lucy gets to the Trojans, it will fly by Donaldjohanson (another main belt asteroid) to allow additional tests of the spacecraft’s procedures and systems.

2^nd November – Galactic 05 mission launch

Set to become Virgin Galactic’s sixth flight in six months, Richard Branson’s spaceflight company will fly its fifth commercial suborbital mission from the world's first purpose-built commercial spaceport - Spaceport America in New Mexico. The flight will reach an altitude of about 87km. There will be three passengers aboard this research flight on the VSS Unity spaceplane - including an unnamed private astronaut of Franco-Italian nationality; planetary scientist Alan Stern (the principal investigator of NASA's New Horizons Pluto mission), and Kellie Gerardi - a science communicator and bioastronautics researcher for the International Institute for Astronautical Sciences (IIAS). The launch window opens on 2^nd November.

9^th November – close approach / conjunction of the Moon and Venus

During the morning of 9^th November, the extremely thin crescent moon will be in conjunction (sharing the same right ascension – coordinate) with Venus. Whilst they’ll both be above the horizon, they’ll be hard to spot in the daylight. Instead look for the pair a little earlier, in the hours just before sunrise – they’ll be in close approach of one and other and will be up in the south-east. It would help to try to find a clear observing location without tall buildings/trees that may usually block your view. They’ll be visible to the naked eye and could be seen together through a pair of binoculars but will be too far separated to be seen within the field of view of a telescope.

11^th/12^th November – peak of the Northern Taurid meteor shower

The Taurid meteor shower is composed of two streams: The Southern Taurids which peak between 4^th and 5^th November and the Northern Taurids which peak between 11^th and 12^th November.

It’s a weaker shower with 5-10 meteors per hour at its peak, produced by dust left behind by the small comet Encke. The Taurids don’t have very definite peaks and instead ramble along in October and November and are especially noticeable from late October into early November when they overlap. Best viewing will be from a dark location after midnight on the 11^th into the early hours of the 12^th . Meteors will radiate from the constellation of Taurus (in the south around midnight) but can appear anywhere in the sky. The waning crescent moon will be below the horizon through the night, so moonlight interference shouldn’t be a problem. The Taurids are rich in fireballs (particularly bright meteors) but their rate is low. When Taurids appear, they’re big and bright but you’re likely to only see a few meteors per hour – still, it’s well worth a watch but you’ll need patience. A blog about the Taurid meteor shower 2023 will soon be up on our website: https://www.spacecentre.co.uk/news/space-now-blog/

13^th November – new moon (9:27am)

The new moon on 13^th will occur in the constellation of Libra. We have a blog on ‘phases of the moon’ written by Mike Darch in our Space Comms team: What are the Phases of the Moon? (spacecentre.co.uk).

17^th/18^th November – peak of the Leonid meteor shower

A minor shower, ~ 10 meteors per hour at its peak, produced by dust left behind by Comet Tempel-Tuttle. The meteors will radiate from the constellation of Leo (rising above the eastern horizon after midnight) but can appear anywhere in the sky. Peaking on the night of the 17^th and into the morning of the 18^th, the waning crescent moon will be below the horizon throughout the night so there should be no moonlight interference to block out the fainter meteors this year. If viewing is done from a dark location, it may be possible to catch a few meteors during this minor shower. The radiant will continue to rise higher into the sky during the early morning of the 18^th, so it might be best to head out after midnight and look until just before sunrise when the radiant will be in the south-east. Occasionally, the display turns sublime: every 33 years or so, there have been instances of the Leonids producing meteors at a rate of about 1,000 — or more — in an hour! However, this won't happen again until 2034. A blog about the Leonid meteor shower 2023 will soon be up on our website: https://www.spacecentre.co.uk/news/space-now-blog/

20^th November – close approach / conjunction of the Moon and Saturn

On the afternoon of 20^th November, the waxing gibbous moon will be in conjunction (sharing the same right ascension – coordinate) with Saturn. At the time of conjunction, the moon will just be rising above the horizon and Saturn will be lost in the glare of daylight. So instead look for the pair in the southern sky that evening as the sun begins to set until around 11:00pm when they’ll fall out of view in the west. They should be high enough above the horizon to spot but it’s always helpful to have a clear view of the horizon without tall buildings and trees to view them easily. They’ll be visible to the naked eye and through a pair of binoculars but too far separated to be seen within the field of view of a telescope. Check out the astronomical phenomena blog above to find out more about conjunctions and other astronomical phenomena.

25^th November – close approach / conjunction of the Moon and Jupiter

During the morning of 25^th November, the waxing gibbous moon will be in conjunction (sharing the same right ascension – coordinate) with Jupiter. At the time of conjunction (roughly 11:00am), the pair will be below the horizon. Instead you can catch the pair in close approach during the very early hours of the 25^th – look to the west around 2:00/3:00am – the pair will be quite close to the horizon so try and find a clear view, unobstructed by trees and buildings, if you can. If you’re not an early riser or don’t fancy staying up so late, you can also catch the pair in close approach in the east after the sun sets later that day (they’ll be a little more separated then). You won’t be able to see them both in the same field of view of a telescope and may struggle with a pair of binoculars too, but you’ll easily be able to spot them with the naked eye if the weather plays ball.

27^th November – full moon (9:16am)

Known as the Beaver moon (according to the old Farmers’ Almanac), it marks the time of year when people would set beaver traps, or when beavers became very active building dams, getting ready for winter.
