What's Up? - May 2018

What’s Up For May?

The Moon and Saturn meet Mars in the morning as our InSight spacecraft launches to the Red Planet on May 5!

You won't want to miss red Mars in the southern morning skies this month.

InSight, our first mission to explore Mars' deep interior, launches on May 5th with a launch window that begins at 4:05 a.m. PDT and lasts for two hours.

Some lucky viewers in central and southern California and even parts of the Mexican Pacific coast will get a chance to see the spacecraft launch with their unaided eyes AND its destination, Mars, at the same time.

Mars shines a little brighter than last month, as it approaches opposition on July 27th. That's when Mars and the Sun will be on opposite sides of the Earth. This will be Mars' closest approach to Earth since 2003! 

Compare the planet's increases in brightness with your own eyes between now and July 27th. 

The Eta Aquarid meteor shower will be washed out by the Moon this month, but if you are awake for the InSight launch anyway, have a look. This shower is better viewed from the southern hemisphere, but medium rates of 10 to 30 meteors per hour MAY be seen before dawn.

Of course, you could travel to the South Pacific to see the shower at its best!

There's no sharp peak to this shower--just several nights with good rates, centered on May 6th. 

Jupiter reaches opposition on May 9th, heralding the best Jupiter-observing season, especially for mid-evening viewing. That's because the king of the planets rises at sunset and sets at dawn. 

Wait a few hours after sunset, when Jupiter is higher in the sky, for the best views. If you viewed Jupiter last month, expect the view to be even better this month!

What’s Up for July 2017

Prepare for the August total solar eclipse by observing the moon phases this month. Plus, two meteor showers peak at the end of July.

Solar eclipses occur when the new moon passes between the Earth and the sun and moon casts a traveling shadow on Earth. A total solar eclipse occurs when the new moon is in just the right position to completely cover the sun’s disk.

This will happen next month on August 21, when the new month completely blocks our view of the sun along a narrow path from Oregon to South Carolina.

It may even be dark enough during the eclipse to see some of the brighter stars and few planets!

Two weeks before or after a solar eclipse, there is often, but not always, a lunar eclipse. This happens because the full moon, the Earth and the sun will be lined up with Earth in the middle.

Beginning July 1, we can see all the moon’s phases.

Many of the Apollo landing sites are on the lit side of the first quarter moon. But to see these sites, you’ll have to rely on images for lunar orbiting spacecraft.

On July 9, the full moon rises at sunset and July 16 is the last quarter. The new moon begins on July 23 and is the phase we’ll look forward to in August, when it will give us the total solar eclipse. The month of July ends with a first quarter moon.

We’ll also have two meteor showers, both of which peak on July 30. The Delta Aquarids will have 25 meteors per hour between midnight and dawn.

The nearby slow and bright Alpha Capricornids per at 5 per hour and often produce fireballs.
