HARVEST MOON

Space Weather News for Sept. 12, 2008
http://spaceweather.com

HARVEST MOON: This weekend's full Moon has a special name--the Harvest Moon. It's the full Moon closest to the northern autumnal equinox. In years past, farmers depended on the light of the Harvest Moon to gather ripening crops late into the night. Post-Edison, we appreciate it mainly for its beauty. Be alert in the nights ahead for Harvest Moon halos, coronas and 'dogs. Visit http://spaceweather.com for example and more information.

AURORA WATCH: Around the Arctic Circle, moonlight will compete with Northern Lights. A solar wind stream flowing from a coronal hole on the sun is due to hit Earth on Sept. 13th or 14th, possibly sparking high-latitude geomagnetic storms. Sky watchers from Alaska to Scandinavia should be alert for auroras.

Volcanic Sunsets

Space Weather News for Aug 31, 2008
http://spaceweather.com

Sky watchers across the USA and Europe are reporting unusually colorful sunsets and sunrises. The cause appears to be the August 7th eruption of the Kasatochi volcano in Alaska's Aleutian islands. The volcano hurled a massive cloud of ash and sulfur dioxide into the stratosphere; high winds have since carried the aerosols over parts of the USA and Europe. "Violet domes," long pink rays crossing the sky, campfire-red aureoles around Venus--these are just a few of the sights documented on Spaceweather.com in recent days. When the sun goes down tonight, look west. You may be in for a treat.

Ongoing coverage of the phenomenon may be found at http://spaceweather.com .

First reports of the volcanic sunsets are documented in the Aug. 27th edition of SpaceWeather.com, located in our archives at this URL:

Fishing for a faint fuzzy

This week's sky

Fishing for a faint fuzzy

Star-party attendees in late August and early September should set their sights on the 10th-magnitude interloper C/2007 W1 (Boattini). It will be well-placed in the east by late evening and remain up the rest of the night. To catch this comet, you'll need to be out under a dark sky and avoid the Moon's unwanted light. As Boattini slides across the back of Pisces the Fish, the comet will resemble some of the fainter Messier objects. You should get a nice view through a 4-inch scope under good conditions.

At best, Boattini will show a stubby tail. The solar system conspires against us this month, because the comet's tail extends mostly behind it from our perspective. In this respect, it mimics last year's appearance of Comet 17P/Holmes.

At September's close, Comet C/2007 W1 passes close to Psi1 Piscium, an easy double star for small telescopes. Its components shine at magnitudes 5.4 and 5.6 and have a comfortable separation of 30". Can you see any color difference between the two stars?

If you're in a comet-hunting mood, lots of other targets await those with bigger scopes. Almost a dozen glow at 12th magnitude or brighter. For up-to-date finder charts and magnitudes, click here.

COUNTDOWN TO THE PERSEIDS

Space Weather News for August 5, 2008
http://spaceweather.com

COUNTDOWN TO THE PERSEIDS: The annual Perseid meteor shower peaks one week from today, on Tuesday, August 12th. The best time to look is during the dark hours before dawn on Tuesday morning when forecasters expect 50 to 100 meteors per hour. Get away from city lights if you can; plan a camping trip! The darker the sky, the more meteors you will see.

The source of the Perseids is Comet Swift-Tuttle, which has littered the August portion of Earth's orbit with space dust. The dusty zone is broad and Earth is already in its outskirts. As a result, even before the peak on August 12th, you may see some "early Perseids" streaking across the night sky. Photos of these early arrivals will be featured in the days ahead on http://Spaceweather.com as part of our full coverage of the Perseid meteor shower.

BONUS: Last Friday's total solar eclipse is history, but new pictures continue to appear in our photo gallery. Start browsing at this URL: http://spaceweather.com/eclipses/gallery_01aug08_page3.htm

DESCENDING SPACE JUNK

Space Weather News for July 22, 2008
http://spaceweather.com

DESCENDING SPACE JUNK: Almost exactly one year ago, on July 23, 2007, International Space Station astronauts threw an obsolete, refrigerator-sized ammonia reservoir overboard. The 1400-lb piece of space junk has been circling Earth ever since and now, in July 2008, its orbit has decayed so much that it has become an easy naked-eye target for backyard sky watchers. The "Early Ammonia Servicer" (EAS for short) is almost as bright as the stars of the Big Dipper and growing brighter as it descends. Today's edition of http://spaceweather.com displays photos of the EAS, which is expected to burn up in Earth's atmosphere in late 2008 or early 2009. Readers who wish to see the EAS with their own eyes should check the Simple Satellite Tracker for flyby times: http://spaceweather.com/flybys. Europeans are favored with flybys this week, North Americans next week.

Scientists in Siberia are nearing the end of their expedition to study the ecology of Arctic landscapes and how they are responding to climate change. Recent blogs from the field describe the challenging terrain of the Siberian Traps, the discovery of 700-year-old tree skeletons, and NASA ecologist Jon Ranson's sparring match with "the one that got away."

Look for fireworks from Aquarius


Astronomy: Roen Kelly


The sky this month


Look for fireworks from Aquarius

The summer meteor season begins with a favorable display from the Delta Aquarids. The meteor shower, which is active from mid-July to mid-August, peaks July 27.

This shower favors observers in the southern half of North America. The reason: Southern latitudes place the radiant higher in the sky.

Observing Delta Aquarid meteors just got a little easier. According to the International Meteor Organization, several faint summer showers with reported radiants near Aquarius confused observers. Several new studies, however, indicate the Delta Aquarid radiant is the only real one.

The Delta Aquarid shower produces between 10 and 20 fast - but not especially bright - meteors per hour. The Last Quarter Moon July 25 will create only minor interference with your meteor hunt.

PRETTY SKY ALERT

Space Weather News for July 16, 2008
http://spaceweather.com

PRETTY SKY ALERT: The brightest lights in the night sky are having a get-together. On July 16th and 17th, Jupiter and the nearly-full Moon will be side-by-side in the constellation Sagittarius. The pair rise in the southeast just after nightfall and remain visible all night long. That's not all: The International Space Station is making a series of evening passes over Europe and North America and it will join Jupiter and the Moon over many towns and cities. Check the Simple Satellite Tracker to find out when to look: http://spaceweather.com/flybys

COLLIDING STORM UPDATE: Earlier this month, Jupiter's Little Red Spot got caught between two larger storms (the Great Red Spot and Oval BA), and the Little Red Spot was destroyed. Or was it? New amateur photos of Jupiter show that the Little Red Spot may be re-forming. Not only that, it seems to be drifting back toward the Great Red Spot for a second collision. Updates will be posted on http://spaceweather.com as the storms converge anew.

What's wrong with the Sun?

NASA Science News for July 11, 2008
The sun is entering its third year of eerie calm. Sunspots are rare and solar flares simply aren't happening. Is this "solar minimum" lasting longer than it should? A NASA scientist has examined centuries of sunspot data to find the answer, revealed in today's story from Science@NASA:

JUPITER AT ITS BRIGHTEST: Jupiter reaches maximum brilliance this week, on July 9th, when it makes its closest approach to Earth for all of 2008. At sunset, look low and southeast for a beacon of light brighter than any star. That is Jupiter rising for an all-night transit across the southern sky. During this time of closest approach, Jupiter makes a wonderful target for backyard telescopes. Even small telescopes reveal the planet's cloud belts, its four largest moons, and the Great Red Spot, an anti-cyclone twice as wide as Earth. Just a few days ago, the Great Red Spot ran over a sibling, the Little Red Spot, and may have destroyed the smaller storm. Amateur images of the collision are featured on today's edition of http://spaceweather.com

A crescent Moon joins Saturn, Mars, and Regulus



The sky this month


A crescent Moon joins Saturn, Mars, and Regulus

Astronomy: Roen Kelly

Binoculars will reveal a beautiful color contrast between orange Mars and bluish-white Regulus. Set against twilight's deepening azure sky, this is one of the summer's finest binocular sights. On July 4, enjoy the "red, white, and blue" of Mars, Regulus, and the early evening sky as America celebrates Independence Day.

Each night, Mars pulls farther from Regulus and draws closer to Saturn. On July 5, when the three objects span a straight line 5° long, they're joined by the 3-day-old crescent Moon 5° below Regulus. The next night, the Moon glows nearly 7° to the left of Mars.

Watch over the following 4 nights as Mars edges toward its July 10 conjunction with Saturn. Then, only about 0.7° separates the two worlds and both will be visible in a telescope's low-power field of view. Here's an opportunity to study a new color contrast, but a more subtle one. Compare Mars' orange hue to Saturn's wan, yellowish tint. Can you spot the difference?

Saturn, shining at magnitude 0.8, is nearly a full magnitude brighter than Mars. This is the ringed planet's last month of visibility before it slips into the solar glare. The Sun will hide Saturn for about 2 months before the planet reappears in the morning sky. Saturn remains so low that telescopic viewing won't reveal much in the early evening's unstable air. But take a quick glimpse at the planet's narrowing rings. They'll be even more edge-on when Saturn reappears in the fall.


Hoping for a clear sky! Happy 4th! :)

Planets Align for the 4th of July.. Don't forget! :)

NASA Science News for July 1, 2008
Look beyond the fireworks on 4th of July weekend. A trio of worlds is converging for a pretty sunset sky show.

FULL STORY at

http://science.nasa.gov/headlines/y2008/01jul_4thofjuly.htm?list874246


July 1, 2008: News Flash: On 4th of July weekend, NASA forecasts lights in the sky.

No, not those lights. Look beyond the fireworks. Almost halfway up the western sky, just above the twilight glow of sunset, a trio of worlds is gathering: Saturn, Mars and the crescent Moon.



Above: Fireworks over Jodrell Bank, England, on the 2008 summer solstice. Photo credit: Andrew Greenwood.

The show gets going on Friday, July 4th. Red Mars and ringed Saturn converge just to the left of the bright star Regulus. The three lights make a pretty 1st-magnitude line in the heavens: sky map.


Sign up for EXPRESS SCIENCE NEWS delivery

But that is just the beginning. On Saturday, July 5th, with weekend fireworks at fever pitch, a lovely crescent Moon joins the show. Saturn, Mars, and the Moon trace an even brighter line than the night before: sky map.

Scan a small telescope along the line. You'll see Saturn's rings, the little red disk of Mars, a grand sweep of lunar mountains and craters, and just maybe—flash!—a manmade incendiary. How often do you see fireworks through a telescope?

This is, however, more than just a flashy gathering of planets—it is also a gathering of spaceships and robots.

Each of the three worlds is orbited or inhabited by probes from Earth. Saturn has the Cassini spacecraft, studying the gas giant's storms, moons and rings. The Moon has two probes in orbit: Kaguya from Japan and Chang'e-1 from China. The pair, operating independently, are mapping the Moon and scanning for resources in advance of future human landings. NASA's Lunar Reconnaissance Orbiter will join them later this year.

Right: An artist's concept of Lunar Reconnaissance Orbiter slated to launch later this year. [more]

Mars has more probes than the others combined. Three active satellites orbit the red planet: Europe's Mars Express and NASA's Mars Odyssey and Mars Reconnaissance Orbiter. The three not only study Mars with their own instruments, but also form a satellite network in support of NASA's Mars rovers Spirit and Opportunity and Mars lander Phoenix.

None of these mechanical specks are visible in a backyard telescope, but they are there, heralds of a growing human presence in the solar system. Tell that to your buddy at the fireworks show!

During the short night of July 5th, the Moon glides past Mars and Saturn so that nightfall on Sunday, July 6th, brings a different arrangement—a scalene triangle. The triad is easy to find in the hours after sunset. Look west and let the Moon be your guide: sky map.

In the nights that follow, the Moon exits stage left, leaving the others behind. Don't stop watching, though. Saturn and Mars are converging for their closest encounter of the next 14 years. After nightfall on Thursday, July 10th, the two planets will be just ¾ of a degree apart, snug enough to fit behind the tip of your pinky finger held at arm's length: sky map.

Now that's spectacular—no fireworks required.

DOUBLE FLYBY ALERT: Space shuttle Discovery is scheduled to undock from the International Space Station on Wednesday morning, June 11th, at 7:42 am EDT. This means many sky watchers will be able to see the two spaceships flying in tandem, separate but closely-spaced points of light, gliding among the stars on Wednesday night. Double flybys will continue on Thursday the 12th and to a lesser extent on Friday the 13th, with Discovery returning to Earth on Saturday. Southeastern parts of the United States (e.g., Miami and Atlanta) are favored with some particularly good apparitions.

THE DESCENT OF PHOENIX: When NASA's Phoenix probe parachuted to Mars last Sunday, a pair of other spacecraft were orbiting high overhead, watching and listening. While NASA's Mars Reconnaissance Orbiter snapped some jaw-dropping photos of Phoenix's plunge to the surface, Europe's Mars Express orbiter recorded Phoenix's radio transmissions. The eerie-sounding tones have just been beamed back to Earth and you can listen to them by following the links at today's edition of http://spaceweather.com.

CARTWHEEL CME: Imagine a billion-ton cloud of gas launching itself off the surface of the sun and then ... doing a cartwheel. That's exactly what happened on April 9, 2008, when a coronal mass ejection pirouetted over the sun's limb in full view of an international fleet of spacecraft. The cartwheel set off a chain of events that amazed even veteran solar physicists. The full story, and a spectacular movie of a second cartwheel recorded just last week, may be found at http://spaceweather.com

GLOBAL SATELLITE TRACKING: Spaceweather.com's simple Satellite Tracker has gone global. The tool now works not only for US and Canadian readers, but also for sky watchers in countries around the world. This development comes as the International Space Station is making bright and frequent nightly apparitions over Europe, Africa, the Middle East, parts of Asia and Australia. If you live in those areas, give it a try: http://spaceweather.com/flybys

POLLEN CORONAS: Warning, this story may make you sneeze. Swarms of springtime pollen in the northern hemisphere are drifting in front of the sun and making multi-colored coronas (rings of light) in the sky. Unlike circular coronas caused by water droplets in clouds, pollen coronas have strange elliptical shapes dotted by colorful bright patches. Pictures featured on today's edition of http://spaceweather.com show you what to look for.

NOCTILUCENT CLOUDS: On May 5th, experienced sky watchers in Northern Ireland were surprised by a sudden apparition of electric-blue noctilucent clouds (NLCs). This marks an unusually early beginning to the 2008 NLC season and may herald a spectacular summer of high-latitude "night shining" clouds. NLCs first appeared in the 19th century mainly around Earth's poles. Since then, for reasons unknown, they have increased in number and range, with sightings in recent years as far south as Utah and Colorado. Visit http://spaceweather.com to see the first photos of 2008 and to learn what to look for in case NLCs visit your part of the world in the nights ahead.

===============================================


The sky this month


Mars joins M44

Ruddy Mars shines at 1st magnitude, equaling the nearby giant star Pollux. The Red Planet then lies approximately 150 million miles from Earth, so it measures a mere 5.8" across. You'll need a 10-inch or larger telescope to see any appreciable detail.

The best most of us can do is to watch its trek against the background stars. Luckily, Mars has a few good companions this month: A waxing Moon stands 6° to its west May 9, just 4 days after the planet crossed into Cancer. The following night, the Moon stands a similar distance east of the planet.

The best is yet to come. On May 21, Mars lies on the western edge of the Beehive star cluster (M44). The following 2 nights, Mars passes through the cluster. Grab your binoculars May 22 and 23 for a great view. This conjunction also offers the opportunity to take some fine close-up photographs. Mars shines nearly 2 magnitudes brighter than the combined output of the Beehive's few hundred stars.

In September 1859, the sun unleashed a solar flare so intense it was visible to the unaided human eye. A ferocious geomagnetic storm ensued in which Northern Lights descended as far south as Cuba, the Bahamas and Hawaii. Meanwhile, telegraph engineers disconnected their batteries and powered communications by electricity from the auroras! Could it happen again? Read today's story to find out.

AQUARID METEOR SHOWER

Space Weather News for May 4, 2008
http://spaceweather.com

ETA AQUARID METEOR SHOWER: If you see a meteor flit across the sky tonight, it could be a piece of Halley's Comet. Earth is crossing a stream of dusty debris from Halley and this is causing the annual eta Aquarid meteor shower. Sky watchers in the tropics and southern hemisphere (where the shower is most intense) could see as many as 70 meteors per hour during the dark hours before dawn on Monday, May 5th, and Tuesday, May 6th. The show is diminished at northern latitudes where rates may be 15 meteors per hour or less. Check http://spaceweather.com for sky maps and more information.

MERCURY AND THE MOON: Innermost planet Mercury is emerging from the glare of the sun and putting on its best show of the year. A good time to look is Tuesday evening, May 6th, just after sunset when the crescent Moon glides by Mercury in the darkening western sky. A sky map and photos are available at http://spaceweather.com.

FLYBY ALERT: This is a good month for spaceship spotting. On May 1st, the International Space Station (ISS) begins a 4-week series of bright flybys over North America and Europe. In early May, the ISS joins Jupiter and the stars of the Summer Triangle in a glittering pre-dawn sky. Later in the month, increasingly-frequent flybys shift to evening hours and the ISS will be crossing paths with Saturn, the Moon and Mars. US and Canadian readers, check our Simple Satellite Flybys tool to find out when to look: http://spaceweather.com/flybys . (European readers, an international version of the flybys tool will be available in the near future. Stay tuned.)

EXPLORE THE IONOSPHERE: The ionosphere is our planet's "final frontier." A realm of dancing auroras, radio-bending plasma bubbles and dangerous ultraviolet rays, it is the last wisp of Earth's atmosphere that astronauts leave behind when they enter space. Now you can explore the ionosphere from the safety of your own home. Yesterday, NASA-supported researchers unveiled a "4D" computer model for the general public. Download a few files and presto--you're flying through the ionosphere. The model shows the ionosphere as it is right now; it's a real-time display based on current solar activity and atmospheric conditions. Visit http://spaceweather.com to get started.

STRANGE SOLAR FLARE: No sunspots? No problem. Yesterday the blank sun unleashed a solar flare without the usual aid of a sunspot. At 1408 UT on April 26th, Earth-orbiting satellites detected a surge of X-rays registering B3.8 on the "Richter scale" of solar flares. That's a relatively minor flare; nevertheless, the blast sent a "solar tsunami" shock wave rippling through the sun's atmosphere and also launched a coronal mass ejection. The CME is expected to reach Earth late on April 28th or April 29th, possibly sparking high latitude auroras when it arrives. Visit http://spaceweather.com to view images, movies and updates.

NASA Broadcasts Earth Views in High Definition

NASA Broadcasts Earth Views in High Definition
By SPACE.com Staff

posted: 18 April 2008
05:38 pm ET


NASA is giving Earth folk a new view of their home planet in high-definition (HD), as seen through the eyes of astronauts of past shuttle and International Space Station missions.

The hour-long special includes crisp views of Earth's oceans and continents that only astronauts have been privy to while floating in orbit.

NASA aired the HD broadcast on NASA TV early Friday as a silent film of serene Earth views. A replay is scheduled for the same time on Monday, and will air all day long from 6 a.m. to 8 p.m. EDT (1000-1200 GMT) on April 22. The replays include a discussion of the Earth views by Justin Wilkinson, a scientist with the Crew Earth Observations Office at NASA's Johnson Space Center in Houston.

The footage will also run on standard NASA TV during regularly scheduled Video File broadcasts.

The astronaut-shot Earth views mark the latest in a series of efforts to view space in high-definition video, whether looking at Earth, the moon or spacecraft interiors.

Japan's Kaguya lunar orbiter captured HD video of Earth-rise while orbiting the moon on April 5, and Japan's tour bus-sized Kibo laboratory on the International Space Station will also host an HD camera once it is completely assembled. The Kibo lab's large pressurized segment is slated for launch in late May aboard a NASA shuttle.

The Discovery Channel also plans on airing a miniseries this year featuring never-before-seen footage of NASA missions restored in high-definition.

The Sky this month...

A tale of two streams

Image Hosted by ImageShack.us



Seeing meteors pepper the sky from the direction of Lyra is a regular April event. Unfortunately, moonlight significantly hinders observations of this year's Lyrid meteor shower. The Lyrids peak near midnight EDT the night of April 21/22, when a waning gibbous Moon stands in Libra. To get a decent view, watch before dawn April 22 from a spot where trees or buildings block the Moon. A better opportunity to see meteors arises in April's final days. Although the Eta Aquarid shower doesn't peak until May's first week, its annual run begins late this month. The meteors come from debris left behind by Comet 1P/Halley during its passages through the inner solar system. The International Meteor Organization reports an apparent 12-year activity cycle for the Eta Aquarids. This could boost rates from 2008 to 2010. So, despite the radiant's low altitude from the Northern Hemisphere, watch for the Eta Aquarids' typically long streaks.

Strange things may be happening on the full Moon when it gets hit by Earth's magnetic tail.

NASA-supported researchers have realized that strange things may be happening on the full Moon when it gets hit by Earth's magnetic tail.

FULL STORY at
http://science.nasa.gov/headlines/y2008/17apr_magnetotail.htm?list874246



The Moon and the Magnetotail
04.17.2008

April 17, 2008: Behold the full Moon. Ancient craters and frozen lava seas lie motionless under an airless sky of profound quiet. It's a slow-motion world where even a human footprint may last millions of years. Nothing ever seems to happen there.

Right?

Wrong. NASA-supported scientists have realized that something does happen every month when the Moon gets a lashing from Earth's magnetic tail.

"Earth's magnetotail extends well beyond the orbit of the Moon and, once a month, the Moon orbits through it," says Tim Stubbs, a University of Maryland scientist working at the Goddard Space Flight Center. "This can have consequences ranging from lunar 'dust storms' to electrostatic discharges."

Yes, Earth does have a magnetic tail. It is an extension of the same familiar magnetic field we experience when using a Boy Scout compass. Our entire planet is enveloped in a bubble of magnetism, which springs from a molten dynamo in Earth's core. Out in space, the solar wind presses against this bubble and stretches it, creating a long "magnetotail" in the downwind direction: diagram.

Anyone can tell when the Moon is inside the magnetotail. Just look: "If the Moon is full, it is inside the magnetotail," says Stubbs. "The Moon enters the magnetotail three days before it is full and takes about six days to cross and exit on the other side."

It is during those six days that strange things can happen.

During the crossing, the Moon comes in contact with a gigantic "plasma sheet" of hot charged particles trapped in the tail. The lightest and most mobile of these particles, electrons, pepper the Moon's surface and give the Moon a negative charge.

On the Moon's dayside this effect is counteracted to a degree by sunlight: UV photons knock electrons back off the surface, keeping the build-up of charge at relatively low levels. But on the nightside, in the cold lunar dark, electrons accumulate and voltages can climb to hundreds or thousands of volts.

Walking across the dusty charged-up lunar terrain, astronauts may find themselves crackling with electricity like a sock pulled out of a hot dryer. Touching another astronaut, a doorknob, a piece of sensitive electronics—any of these simple actions could produce an unwelcome zap. "Proper grounding is strongly recommended," advises Stubbs.

The ground, meanwhile, may leap into the sky. There is compelling evidence (see, e.g., the Surveyor 7 image below) that fine particles of moondust, when sufficiently charged-up, actually float above the lunar surface. This could create a temporary nighttime atmosphere of dust ready to blacken spacesuits, clog machinery, scratch faceplates (moondust is very abrasive) and generally make life difficult for astronauts.

Stranger still, moondust might gather itself into a sort of diaphanous wind. Drawn by differences in global charge accumulation, floating dust would naturally fly from the strongly-negative nightside to the weakly-negative dayside. This "dust storm" effect would be strongest at the Moon's terminator, the dividing line between day and night.

Much of this is pure speculation, Stubbs cautions. No one can say for sure what happens on the Moon when the magnetotail hits, because no one has been there at the crucial time. "Apollo astronauts never landed on a full Moon and they never experienced the magnetotail."
The best direct evidence comes from NASA's Lunar Prospector spacecraft, which orbited the Moon in 1998-99 and monitored many magnetotail crossings. During some crossings, the spacecraft sensed big changes in the lunar nightside voltage, jumping "typically from -200 V to -1000 V," says Jasper Halekas of UC Berkeley who has been studying the decade-old data.


"It is important to note," says Halekas, "that the plasma sheet (where all the electrons come from) is a very dynamic structure. The plasma sheet is in a constant state of motion, flapping up and down all the time. So as the Moon orbits through the magnetotail, the plasma sheet can sweep across it over and over again. Depending on how dynamic things are, we can encounter the plasma sheet many times during a single pass through the magnetotail with encounters lasting anywhere from minutes to hours or even days."

"As a result, you can imagine how dynamic the charging environment on the Moon is. The Moon can be just sitting there in a quiet region of the magnetotail and then suddenly all this hot plasma goes sweeping by causing the nightside potential to spike to a kilovolt. Then it drops back again just as quickly."

The roller coaster of charge would be at its most dizzying during solar and geomagnetic storms. "That is a very dynamic time for the plasma sheet and we need to study what happens then," he says.

What happens then? Next-generation astronauts are going to find out. NASA is returning to the Moon in the decades ahead and plans to establish an outpost for long-term lunar exploration. It turns out they'll be exploring the magnetotail, too.

Solar Wind vs. Magnetotail: Earth's magnetotail isn't the only source of plasma to charge the Moon. Solar wind can provide charged particles, too; indeed, most of the time, the solar wind is the primary source. But when the Moon enters the magnetotail, the solar wind is pushed back and the plasma sheet takes over. The plasma sheet is about 10 times hotter than the solar wind and that gives it more "punch" when it comes to altering the charge balance of the Moon's surface. Two million degree electrons in the plasma sheet race around like crazy and many of them hit the Moon's surface. Solar wind electrons are relatively cool at only 140 thousand degrees, and fewer of them zip all the way down to the shadowed surface of the Moon's nightside.
