NASA's Multipurpose Mars Mission Successfully Launched

A seven-month flight to Mars began this morning for NASA's Mars Reconnaissance Orbiter (MRO). It will inspect the red planet in fine detail and assist future landers.

An Atlas V launch vehicle, 19 stories tall with the two-ton spacecraft on top, roared away from Launch Complex 41 at Cape Canaveral Air Force Station at 7:43 a.m. EDT. Its powerful first stage consumed about 200 tons of fuel and oxygen in just over four minutes, then dropped away to let the upper stage finish the job of putting the spacecraft on a path toward Mars. This was the first launch of an interplanetary mission on an Atlas V.

"We have a healthy spacecraft on its way to Mars and a lot of happy people who made this possible," said James Graf, project manager for MRO at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif.

MRO established radio contact with controllers 61 minutes after launch and within four minutes of separation from the upper stage. Initial contact came through an antenna at the Japan Aerospace Exploration Agency's Uchinoura Space Center in southern Japan.

Health and status information about the orbiter's subsystems were received through Uchinoura and the Goldstone, Calif., antenna station of NASA's Deep Space Network. By 14 minutes after separation, the craft's solar panels finished unfolding, enabling the MRO to start recharging batteries and operate as a fully functional spacecraft.

The orbiter carries six scientific instruments for examining the surface, atmosphere and subsurface of Mars in unprecedented detail from low orbit. For example, its high-resolution camera will reveal features as small as a dishwasher. NASA expects to get several times more data about Mars from MRO than from all previous Martian missions combined.

Researchers will use the instruments to learn more about the history and distribution of Mars' water. That information will improve understanding of planetary climate change and will help guide the quest to answer whether Mars ever supported life. The orbiter will also evaluate potential landing sites for future missions. MRO will use its high-data-rate communications system to relay information between Mars surface missions and Earth.

Mars is 72 million miles from Earth today, but the spacecraft will travel more than four times that distance on its outbound-arc trajectory to intercept the red planet on March 10, 2006. The cruise period will be busy with checkups, calibrations and trajectory adjustments.

On arrival day, the spacecraft will fire its engines and slow itself enough for Martian gravity to capture it into a very elongated orbit. The spacecraft will spend half a year gradually shrinking and shaping its orbit by "aerobraking," a technique using the friction of carefully calculated dips into the upper atmosphere to slow the vehicle. The mission's main science phase is scheduled to begin in November 2006.

The launch was originally scheduled for August 10, but was delayed first due to a gyroscope issue on a different Atlas V, and the next day because of a software glitch.

The mission is managed by JPL, a division of the California Institute of Technology, Pasadena, for the NASA Science Mission Directorate. Lockheed Martin Space Systems, Denver, prime contractor for the project, built both the spacecraft and the launch vehicle.

NASA's Launch Services Program at the Kennedy Space Center is responsible for government engineering oversight of the Atlas V, spacecraft/launch vehicle integration and launch day countdown management.

NASA's Mars Orbiter Launch Delayed 24 Hours

The launch of NASA's Mars Reconnaissance Orbiter (MRO) has been postponed. The new launch window is 7:43 to 9:43 a.m. EDT, Friday, August 12.

The delay was called after engineers saw an anomalous reading in the hydrogen propellant loading system on the Atlas V. There was insufficient time in the launch window to fully investigate the reading. The Atlas V vehicle is being de-tanked. The rocket will remain on the launch pad, and the MRO spacecraft is secured.

Tomorrow's weather forecast calls for a chance for isolated coastal showers. There is a 20 percent probability of not meeting the launch weather criteria.

On launch day, August 12, the KSC News Center will open at 4:30 a.m. EDT. Foreign national news media should meet at Gate 1 at Cape Canaveral Air Force Station at 5 a.m. to be escorted to the KSC Press Site. NASA TV live coverage of the launch begins at 5:15 a.m. EDT.

Skynotes Pahe Updated With Perseid Info

A number of resources on the Perseids (audio, video and websites) have been added to the Events for August 2005 section of the Skynotes page. The Perseids shower is now underway.

Mars and the Perseid Meteor Shower

The Perseid meteor shower is underway. The shower's broad peak extends from August 11th through 13th, with August 12th being best. If you get away from bright city lights and watch the sky between local midnight and dawn on Friday morning, August 12th, you can expect to see dozens to hundreds of meteors.

The planet Mars is out during the Perseid meteor shower, too. It's that bright red "star" high in the eastern sky before dawn. Many Perseid meteors will appear to fly past Mars on Friday morning--a pretty sight.

And speaking of Mars, beware the Mars Hoax. A rumor about the red planet continues to spread via email. The message claims that Mars will come so close to Earth on August 27th that it looks as big as the full Moon. In fact, Mars is approaching Earth for a close encounter in October--not August. October's close approach will indeed be beautiful, but Mars will never rival the Moon.

New Telescope Store

I've added a new telescope store to the Night Sky Observer website that lists a wide selection of telescopes ranging in objective size from 2.5" to 11". There's a mixture of refractors and reflectors such as dobsonians, schmidt-cassegrains, ritchey-chretien, etc. Manufacturers include Meade, Celestron, Tele-Vue, Vixen, Takahashi and Konus.

Larger telescopes will be added soon along with accessories so stay tuned!


The Persieds Are Coming!

Don't forget, the Perseid meteor shower peaks on Friday morning, August 12th. No matter where you live, the best time to look will be during the hours before local dawn when the constellation Perseus is high in the sky. While August 12th is best, the nights before and after the 12th can be good, too. Even now, sky watchers are seeing occasional bright Perseids before dawn.

Also, you can listen to the shower. Meteor radars are monitoring the skies above the USA; when a Perseid flies overhead, they record an audible "ping." Visit SpaceWeather.com for live audio, plus more information about the Perseids.
