Cosmic Background

Spitzer Space Telescope image of the cosmic infrared background

This infrared view (click to enlarge) from the Spitzer Space Telescope team reveals the cosmic background when the universe was less than one billion years old. The light probably originated from the universe's very first groups of objects - huge stars or voracious black holes. In this image darker shades correspond to dimmer parts of the background glow, while yellow and white show the brightest light. The image was created from Spitzer data that was processed to mask out stars, galaxies and other sources. The Spitzer mission is managed for NASA by JPL in Pasadena, Calif.

Lake Effect Snow

Satellite image of Lake Effect Snow

Streamers of snow streak from the Great Lakes in this Terra satellite MODIS instrument image (click to enlarge) taken on December 9. The white swath extending from Lake Michigan to the lower left was deposited by a powerful storm that left thousands without power for many days. The snow on the southeastern side of the Great Lakes fell as lake-effect snow when icy winds blew across the lakes, picked up the relatively warm, moist air, and pushed it over the colder land, where it condensed into snow. The MODIS instrument was built by Santa Barbara Remote sensing in Goleta, California. Image and caption courtesy MODIS Land Rapid Response Team, NASA GSFC

Nuclear Blast Detection Antennas Delivered

(NOV 6) CARPINTERIA, Calif. -- Northrop Grumman Corporation has delivered all V-Sensor deployable antenna assemblies that will be used to detect nuclear blasts as an adjunct payload on the Global Positioning Satellite 2F program.

The company's Astro Aerospace unit completed manufacturing and testing this summer of six qualification units and 18 flight units of its V-Sensor deployable antenna assemblies and recently delivered them to its customer, Los Alamos National Laboratory.

The "pop-up" antennas are an example of Astro Aerospace's Storable Tubular Extendible Member (STEM) product line, which can be stowed in compact packages for launch and then opened in orbit. About the size of a pack of cigarettes, these STEM antennas deploy to a length of almost seven feet. They permit detection of electromagnetic pulses as part of nuclear arms control.

These antenna assemblies will be integrated on the next generation of GPS satellites by prime contractor The Boeing Company. Astro Aerospace also produced antennas for GPS 2R for a similar application.

Mercury Crosses the Sun

(NOV 2) WAUKESHA, WI - Next Wednesday afternoon, the planet Mercury will be visible in silhouette as it slides across the Sun's face. This event, called a transit, lasts about 5 hours as Mercury passes Earth.

People with Internet access can watch the event from their computers thanks to a few live webcasts (Clear skies permitting, of course). For links to the webcasts, visit Astronomy magazine's online media kit for this event at

Advanced observers will watch the planetary shadow play with telescopes and safe solar-viewing equipment and techniques. A properly filtered telescope will provide the best view, because Mercury will appear only 1/194 the size of the Sun. The planet will look like a small, dark sunspot as it moves across the solar surface. Even a brief glimpse of the Sun through a telescope can permanently damage vision, so observers must use safe Sun-viewing techniques.

Mercury begins its journey across the Sun at 2:12 p.m. EST. Astronomers call this moment "first contact." Two minutes later, Mercury's entire disk appears against the Sun's (second contact). For the next 4 hours and 54 minutes, the black dot slowly crosses the brilliant disk. At 7:08 p.m. EST, Mercury reaches the Sun's edge, marking third contact. The transit ends (fourth contact) 2 minutes later.

Observers under clear skies across North America will be able to see portions of the event before sunset, but the entire transit will be visible for those near the West Coast.

White Sands Launch Announced

(SEP 6) The U.S. Army announced today that a test of the Terminal High Altitude Area Defense (THAAD) system is scheduled for the morning of Saturday, September 9 from New Mexico's White Sands Missile Range (WSMR).

The test will involve the launch of a Hera target and a THAAD missile sometime between 04:00 and 06:00 MDT. If the exercise occurs during morning twilight, residents of New Mexico, west Texas, Arizona, and northern Mexico may see an interesting light show as the exhaust of one or both missiles is illuminated by sunlight at high altitude.

This fourth in a series of five tests planned at WSMR will be a fully integrated flight test of all THAAD components. THAAD is currently in its development phase and will be an element of the multi-layered Ballistic Missile Defense System (BMDS), managed by the Missile Defense Agency (MDA).

THAAD uses technologies developed in earlier MDA programs and during the THAAD Program Development and Risk Reduction Phase. It is the first weapon system with both endo- and exo-atmospheric capability developed specifically to defend against ballistic missiles. The THAAD element will provide upper-tier defense in the terminal segment of MDA's BMDS. The BMDS is capable of providing a layered defense for the U.S., deployed forces, friends and allies against ballistic missiles of all ranges in all phases of flight. The higher altitude and theater-wide protection offered by THAAD provides more protection of larger areas than lower-tier systems alone. THAAD is designed to defend against short, medium, and intermediate range ballistic missiles.

The THAAD Program is managed by the Missile Defense Agency in Washington, D.C., and executed by the THAAD Project Office in Huntsville, Ala. Lockheed Martin Corporation is the prime contractor.

Dawn Duo

(AUG 25) Early risers have a chance to see a planetary close encounter this Saturday morning when Venus and Saturn will be separated by only 1/2 of a degree. To spot the pairing, go outside about 45 minutes before sunrise on August 26th and look for dazzling bright, white Venus low in the east. The much fainter Saturn will be just below Venus near the 7 o'clock position.

Although the pairing should easily be visible to the naked eye, you'll need an unobstructed eastern horizon. If you miss Saturday morning's pairing, don't despair. The two planets will also be quite close the next morning except that Saturn will be above and to the right of Venus.

Call for SMART-1 Impact Observations

(AUG 19) The European Space Agency has issued a call for professional and amateur astronomers to participate in the SMART-1 impact observation campaign. The ESA spacecraft will end its lunar science mission by impacting the Moon's Sea of Excellence on the evening of September 2.

A spacecraft maneuver at the end of July will probably cause the impact to occur at one of the following times and locations:

(° S)
(° W)
SEP 2 17:36 SEP 3 00:36 36.4 43.5
SEP 2 22:41 SEP 3 05:41 36.44 46.25

An exact time and place of impact is unavailable because of uncertainties regarding the Moon's topography.

According to SMART-1 project scientist Bernard Foing, if the plume from the impact reaches sunlight, it may be visible with an amateur telescope or binoculars.

For more information on the SMART-1 impact, go to the ESA web site.

Martian Disinformation

(AUG 13) It begins with "The Red Planet is about to be spectacular!" and makes other claims including the Earth and Mars will soon have their closest approach in recorded history, that Mars will be the second brightest object in the night sky, and when viewed through a telescope at a magnification of 75 times, the Red Planet will appear to be as large as the full Moon does to the naked eye.

If you have an e-mail account, chances are you've recently received this recycled item that first made the rounds before our close pass by Mars in 2003. While it may have been true three years ago, it is now completely false.

There will be no close encounter between the two planets this year. The Earth and Mars are now a great distance apart. Rather than being prominent in the night sky, Mars is difficult to find with the unaided eye due to its faintness and its location low in the west at dusk.

As for Mars appearing as a large disk when viewed through a telescope, that is also false. Even when using an excellent amateur telescope under good conditions, the planet would now probably be very tiny and resemble the head of a pin.

Network Leads Astronomers to Major Discoveries

Delta IV Launch On Schedule

(JUN 27) As of 04:45 this morning, this evening's Delta IV rocket launch from Vandenberg AFB appears to be on schedule.

The official L-1 weather forecast issued Monday morning predicted the following conditions at Vandenberg at launch time:


Clouds Coverage Bases (ft) Tops (ft)
Stratus 8/8ths 200 1,700
Altocumulus 6/8ths 16,000 23,000
Cirrus 5/8ths 25,000 33,000

Visibility: 1/2 nautical mile

Weather: Fog

Probability of violation of launch weather constraints: 30%

The above forecast calls for weather that will probably be within acceptable limits for launch. However, the situation for launch viewing probably won't be as favorable due to fog on the ground and cloud layers at different altitudes.

Weather conditions can change in a matter of hours. For the latest weather forecasts for the region, go to:

April Showers Bring Meteors by the Hour

(APR 18) WAUKESHA, WI - The Lyrid meteor shower peaks the night of April 21/22. After midnight, as many as 20 meteors an hour will streak across the sky. The shower's radiant, the point in the sky where they appear to shoot from, lies in the constellation Lyra the Lyre. The waning crescent Moon will stay out of the way that night, so the sky will be dark - and the show should be good. For several nights before and after the peak, fewer meteors will be visible.

All you need to observe a meteor shower is your eyes - and a lawn chair if you don't want to strain your neck. Some people enjoy counting the number of meteors per hour, either by jotting down ticks on a notepad or talking into a tape recorder. Observing a meteor shower can be a great social event, so get some people together Friday night and make it a party.

Spring's warm weather makes the Lyrids the start of meteor-watching season. Watch for the Eta Aquarids later in the month. They'll be visible starting April 19, with a May 6 peak best seen from the Southern Hemisphere. This is one of two showers derived from Halley's Comet (the other is the Orionids in October).

Meteor showers occur when Earth passes through debris left by a passing comet or asteroid. For the Lyrids, the parent comet is C/1861 G1, whose debris enters our atmosphere at some 108,000 mph, a modest speed by meteor standards. Air friction incinerates the dust-size particles, creating the bright but brief flashes of light we see as meteors.

Reentry Vehicle Contract Awarded

(MAR 31) CLEARFIELD, Utah - Northrop Grumman Corporation was awarded a $135 million dollar, six-year contract this week to begin the full-rate production phase of the Minuteman III Intercontinental Ballistic Missile (ICBM) Safety Enhanced Reentry Vehicle (SERV) program.

Under the SERV program, the Minuteman III missile will now carry single Mark 21 reentry vehicles, recently decommissioned from the Peacekeeper force, to ensure continued reliability and effectiveness of the ICBM weapon system. Lockheed Martin and Boeing are principal teammates on this program.

This award follows the third successful flight test of a SERV-modified Minuteman III conducted by the U.S. Air Force on Feb. 16. Along with earlier flight tests in July and August 2005, this latest test proved the successful integration of modified hardware and software into the existing Minuteman III weapon system.

The entire force of 500 Minuteman III missiles is slated to be upgraded with the SERV modifications by 2011.

Lockheed Martin Corporation, Bethesda, Md., developed the electronic and mechanical hardware that interfaces the reentry vehicle with the rest of the Minuteman III missile. Lockheed Martin's Valley Forge, Pa., facility produces the electrical and mechanical hardware, support equipment and associated logistics support.

The Boeing Company, Chicago, Ill., is responsible for modifying flight software, replacing the guidance system and integrating it into the missile.

Venus Bright in Morning Sky

(MAR 20) WAUKESHA, WI - The "morning star" Venus lights the sky before dawn, heralding spring's arrival. On March 25, the brilliant planet reaches its greatest western elongation - when the planet is as far west of the Sun as possible. Then, it sits just above the horizon in the east-southeast sky 2 hours before sunrise. Look for the waning crescent Moon passing to the right of the "morning star." Venus will be the bright object just to the upper left of the Moon.

Each day thereafter, Venus' sky position sinks closer to the horizon. Venus shone at its brightest, magnitude -4.6, in February, but the planet will dominate the morning sky throughout summer.

To the naked eye, Venus' light rivals only moonshine in the early morning sky. But you can use a telescope to watch as the planet changes phases, like the Moon's, during the year. By March 25, its globe measures 25" through a telescope and has fattened to half-lit. It's at its brightest for the year now; even though the phase increases, its angular size decreases as the Earth-Venus distance increases.

Our "sister planet" lies an average of 67 million miles (108 million kilometers) from the Sun. Because Venus lies closer to the Sun than Earth, it always appears close to our star in the sky.

On March 26, Venus and the Moon help you spot a rarely seen planet: Neptune. At about 5 a.m. local time, Venus appears slightly north of (above) Neptune. The Moon lies just below and to the left of the planets.

Dawn Rocket Launch

(MAR 12) A Pegasus rocket carrying a trio of NASA satellites is scheduled for launch from a jumbo jet early this Tuesday. An L-1011 will ferry the Pegasus XL from Vandenberg AFB to a drop point high above the Pacific west-southwest of Monterey, California.

The rocket is slated for release at 06:02 PST on March 14 during a launch window that extends from 05:57:21 to 07:19:50 PST. After a brief free fall, the Pegasus' first stage rocket motor will ignite and the vehicle will begin to climb. If all goes well, the rocket will insert the Space Technology (ST5) payload into a 186 by 2,796 mile polar orbit.

Once in orbit, ST5 will deploy three micro-satellites. The mission will validate innovative technology to reduce risks to future science missions. It will also demonstrate the ability of small satellites to perform research-quality science by taking measurements of Earth's magnetic field using highly sensitive magnetometers.

Assuming a launch early in the window, a weak visual display may be in store for coastal southern California as sunlight illuminates the rocket's exhaust plume during morning twilight. Since daylight Pegasus launches are very difficult to see, Tuesday's event may not be visible to observers located inland due to the sky brightness from the approaching sunrise. The optimum viewing location will likely be western Santa Barbara County.

Navy Destroyer Tracks Minuteman

(FEB 24) USS Hopper (DDG 70), an Arleigh Burke-class destroyer homeported at Pearl Harbor, Hawai'i, participated in the successful "Sky Hunter" Ballistic Missile Defense (BMD) test event off the coast of southern California on Feb. 15.

Using a recent upgrade to its Aegis weapons system, Hopper was tasked with detecting and tracking a Minuteman III Inter-Continental Ballistic Missile (ICBM) launched from Vandenberg Air Force Base, Calif. during the boost and initial ballistic portions of flight and providing cueing data to SPAWAR Space Systems Center (SSC) in San Diego and the Joint National Test Center in Colorado Springs for analysis.

In a role known as long range surveillance and track (LRS&T), Hopper has the capability to detect and track ICBMs and report track data to shore-based components of the missile defense system.

It can further provide fire control data to the ground-based ICBM interceptors located at Fort Greely, Alaska and Vandenberg Air Force Base.

At-sea tracking events, such as "Sky Hunter," have verified the capability of surface ships to track ICBMs and demonstrated the reliability of transmitting track data necessary to support missile defense situational awareness, target cueing and engagements.

Hopper has participated in three successful BMD missions. "Sky Hunter" and "Glory Trip-189" tracked ICBMs launched from Vandenberg.

During "Stellar Valkyrie" in November, Hopper provided cueing and track data on a medium range ballistic missile, which USS Lake Erie (CG 70) acquired and engaged with the newest variant of Standard Missile (SM-3).

Hopper's technicians are excited by the new mission area and the opportunity to flex their system.

"We get invaluable training and technical support from civilian Aegis experts during these missions," said Fire Controlman 2nd class James Wickham.

"I have learned a lot about our system - its capabilities and the future of BMD," said Wickham.

Thirteen Aegis destroyers are currently equipped with the LRS&T capability.

Missile Engineering Center Dedicated

(FEB 21) SAN BERNARDINO, Calif. - Feb. 21, 2006 -- Securing the future of Northrop Grumman Corporation operations in San Bernardino, the company cut the ribbon today on its newly-constructed Missile Engineering Center, located on Hospitality Lane near the junction of Interstates 10 and 215.

Northrop Grumman's presence in San Bernardino spans more than 43 years of critical support to our nation's defense. With more than 230 scientists, engineers and other professionals in the area, the company occupies 85,000 sq. feet in this new three-story location known as Brier Corporate Center.

The Missile Engineering Center serves as a vital proving ground for missile technology development and provides support to several key government missile programs. The center's flagship programs include the ICBM Minuteman III modernization program where Northrop Grumman is the prime contractor responsible for maintaining, sustaining and modernizing the nation's fleet of Minuteman III missiles; and the Kinetic Energy Interceptor program -- a critical boost/ascent or midcourse-phase missile defense program where Northrop Grumman is the prime contractor developing and testing this capability.

Northrop Grumman came to San Bernardino in 1962 when the former TRW Inc. moved into the area from Los Angeles. The company co-located with its customer at Norton Air Force Base to work on the Titan missile and the Minuteman II missile programs. When Norton was closed in 1994, the company temporarily moved off the base while offices were being refurbished by the Inland Valley Development Agency. In February 1996, Northrop Grumman returned to become the first major tenant in the redeveloped former Air Force base.

Mercury Shines Brightest in February

(FEB 17) WAUKESHA, WI - The best time to see Mercury this year is right now. Mercury will brighten as an evening “star” in the western sky until it reaches greatest eastern elongation - when the planet is as far east of the Sun as it can get. The evening of February 23 should provide the best view of Mercury as it shines at -0.5 magnitude, which makes it the second brightest object in the evening sky after the star Sirius.

Not only does Mercury appear bright in the sky at greatest elongation, but the closest planet to the Sun also rises to its highest point in the sky. At greatest elongation, Mercury reaches a maximum of 18° above the horizon February 23 and 24. [For comparison, your closed fist held at arm's length spans 10°.] After February 24, the planet dims nightly. On March 1, it glows at magnitude 0.3.

Mercury orbits the Sun at an average distance of only 36 million miles (58 million kilometers). Earth is nearly 3 times as far, so, from our perspective, Mercury always stays near the Sun.

When Mercury is west of the Sun, we view it as a morning star in the east before sunrise. Some elongations are better than others because of Earth's tilt and the stretched-out nature of Mercury's orbit. Even at its farthest from the Sun, Mercury appears no more than 28° away from the star.

Through a telescope, observers will watch Mercury go through phases similar to the Moon's. On February 8, the planet's disk was more than 90-percent illuminated. At greatest elongation, Mercury's disk will appear half-lit, and it will shrink to a 23-percent-illuminated crescent by March 1.

Most observers detect no surface markings on Mercury. It takes a seasoned observer and excellent atmospheric conditions to see anything at all on the planet, even through the largest amateur telescopes. Experienced amateurs, however, have recorded dusky markings and occasional bright areas on the planet.

Minuteman III Launches from Vandenberg

(FEB 16) VANDENBERG AIR FORCE BASE, Calif. - An unarmed Minuteman III intercontinental ballistic missile was launched from Launch Facility-10 on North Vandenberg at 12:01 a.m. Thursday. More

Minuteman III Launch

(FEB 14) VANDENBERG AIR FORCE BASE, Calif. - An unarmed Minuteman III intercontinental ballistic missile is scheduled to launch from North Vandenberg Thursday morning as part of a developmental test to demonstrate the ability to integrate modified products into weapons systems. The six-hour launch window is from 12:01 a.m. to 6:01 a.m. PST.

The missile will launch under the direction of the 576th Flight Test Squadron here.

Col. Jack Weinstein, 30th Space Wing commander, is the spacelift commander. The mission director is Lt. Col. Stephen Davis, 576th FLTS commander. Members of the 576th FLTS here installed tracking, telemetry and command destruct systems on the missile to collect data and meet safety requirements.

The missile's single unarmed re-entry vehicle is expected to travel approximately 4,800 miles in about 30 minutes, hitting a pre-determined target at the Kwajalein Missile Range in the western chain of the Marshall Islands. The nation’s ICBMs are a key component of global stability - a safe, secure and affordable weapon system that delivers deterrence.

Pleiades Occultations

(FEB 3) Chances are you have noticed the faint, close grouping of stars known as the Pleiades glittering in the winter sky. This Sunday night-Monday morning (February 5-6), the first quarter Moon passes through the Pleiades for observers on the West Coast and Hawaii.

Using a small telescope or binoculars, skywatchers can watch the Moon eclipse (or, as astronomers call it, "occult" from Latin "to hide") members of the star cluster. Whether the Moon occults a given star, as well as the disappearance and reappearance times, varies depending on location.

From downtown Los Angeles, the stars Merope, Alcyone, Atlas, and Pleione disappear at 00:16, 00:56, 01:30, and 01:36 PST (08:16, 08:56, 09:30, and 09:36 UTC), respectively. The reappearances of Merope and Alcyone will be difficult to see due to the Moon's low elevation and because they emerge on the Moon's daylight side. Pleione and Atlas reappear after moonset.

For the disappearance and reappearance times of the brightest Pleiades for other cities, use the following links:

Of particular interest is the gazing occultation of Electra. The Moon will barely occult or graze the star within an extremely narrow zone that runs through southern California. Suitably equipped observers within the path may be able to alternately see the star disappear behind mountains and shine through valleys on the Moon's north pole.

Occultation enthusiasts have identified northern Somis, California as a prime location for observing the graze. The narrow path also passes over Thousand Oaks, part of Los Angeles, and northern Orange County, as well as other locations from south of Santa Maria to the southern Imperial Valley.

Detailed maps, information about a planned expedition to northeastern Orange County, and other information is available at
