A lunar month is shorter than a calendar month.

The spacecraft performed a course correction on 13 August 1973.

The spacecraft performed a course correction on 16 August 1973.

They were integrated with the spacecraft at the General Dynamics ASCENT facility in Gilbert, Arizona.

The lunar far side is on average about higher than the near side.

Chemical rockets provide too much thrust, too much push. The probe would just shoot away.

This lunar month is not just about fasting long hours and stuffing ourselves at the end of the day.

The Venus Express orbiter has been continuously sending back Venus science data since April 11, 2006.

In April 2008, RXTE data was used to infer the size of the smallest known black hole.

The massif became famous in a photo taken in 1976 by the American Viking 1 Orbiter.

According to some traditions, this occurred in approximately the fifth lunar month, while, according to others, it was in the twelfth month.

The gravity assist maneuver was first used in 1959 when the Soviet probe Luna 3 photographed the far side of Earth's Moon.

And I can't tell you what it was like to see the first pictures of Titan's surface from the probe. And this is what we saw.

On December 19, 2000, the spacecraft captured an image of the moon Himalia, but the resolution was too low to show surface details.

In contrast, Voyager 2 began detecting returning particles when it was only 76 AU from the Sun, in May 2006.

Priestley and other Lunar Society members argued that the new French system was too expensive, too difficult to test, and unnecessarily complex.

The Lunar Precursor Robotic Program (LPRP) is a program of robotic spacecraft missions which NASA will use to prepare for future Moon landings.

The probe arrived in Mars' orbit in September 2014, at approximately the same time as India's Mars Orbiter Mission.

Since the Islamic lunar calendar, introduced in 634 A.D., is 11 12 days shorter than the solar calendar, the date of the holiday changes each year.

The calendar The average calendrical month, which is of a year, is about 30.44 days, while the Moon's phase (synodic) cycle repeats on average every 29.53 days.

The near side of the Moon is the lunar hemisphere that is permanently turned towards the Earth, whereas the opposite side is the far side of the Moon.

I'm looking at nerves here. So these are nerves you see, down on the bottom, and the microscope probe that's being held by the robotic hand, up at the top.

In January 2006, it was announced that Rossi had been used to locate a candidate intermediate mass black hole named M82 X 1.

Hayabusa landed on 20 November for thirty minutes, but it failed to operate a device designed to collect soil samples.

The first orbiter, Columbia , launched on 12 April 1981 and returned on 14 April, 54.5 hours later, having orbited the Earth 37 times.

Hundreds have been rescued, but at least 38 people have been confirmed dead and more than 100 people remained missing on the first day of the Lunar New Year.

Probably tilted onto its side, it returned a weak signal, supplying temperature data for 23 minutes, the first telemetry received from the surface of another planet.

The total amount of matter in the universe (including baryons and dark matter), as measured from the CMB spectrum, accounts for only about 30 of the critical density.

It was discovered from the images taken by Voyager 2 on January 20, 1986, and was given the temporary designation S 1986 U 7.

The celebration of the feast in Japan was moved from the 7th day of the first lunar month to the 7th day of January during the Meiji period, when Japan adopted the solar calendar.

Mariner 2 also obtained improved estimates of its mass and of the astronomical unit, but was unable to detect either a magnetic field or radiation belts.

The Moon does appear larger when close to the horizon, but this is a purely psychological effect, known as the Moon illusion, first described in the 7th century BC.

Various mission constraints limited the landing site to Oceanus Procellarum on the lunar equator, which the lander ideally would reach 66 hours after launch.

Indeed, the start of 2005 saw some movement on improved ties, with the introduction of a hugely successful lunar new year charter flights program.

The first photographs of Perdita were taken by the Voyager 2 spacecraft in 1986, but it was not recognized from the photographs for more than a decade.

Far more capable than the Zond, the Apollo spacecraft had the necessary rocket power to slip into and out of lunar orbit and to make course adjustments required for a safe reentry during the return to Earth.

Exploration So far the only close up images of Titania have been from the Voyager 2 probe, which photographed the moon during its flyby of Uranus in January 1986.

The rover will be designed to move on wheels on the lunar surface, pick up samples of soil or rocks, do on site chemical analysis and send the data to the mother spacecraft Chandrayaan II, which will be orbiting above.

The flight was not without difficulty the orbiter was oriented incorrectly and needed to be corrected, unfortunately it took her a day to convince ground control.

Pale Blue Dot is a photograph of planet Earth taken on February 14, 1990, by the Voyager 1 space probe from a record distance of about kilometers ( miles, 40.5 AU), as part of the Family Portrait series of images of the Solar System.

On the tenth day of the fifth lunar month of 1285, Trần Quang Khải fought the decisive battle in the Chương Dương where the Yuan navy was almost destroyed and the balance in the battlefield tilted definitively in favor of the Trần dynasty.

The Emperor died on the 25th day of the fifth lumar month, 1369, at the age of 28, after appointing his brother's son Dương Nhật Lễ despite the fact that his appointee was not from the Trần clan.

Oromo months (stars lunar phases) are Bittottessa (Iangulum), Camsa (Pleiades), Bufa (Aldebarran), Waxabajjii (Belletrix), Obora Gudda (Central Orion Saiph), Obora Dikka (Sirius), Birra (full moon), Cikawa (gibbous moon), Sadasaa (quarter moon), Abrasa (large crescent), Ammaji (medium crescent) and Gurrandala (small crescent).

Evidence presented at a meeting of the American Geophysical Union in May 2005 by Dr. Ed Stone suggests that the Voyager 1 spacecraft passed the termination shock in December 2004, when it was about 94 AU from the Sun, by virtue of the change in magnetic readings taken from the craft.

So this is what we started with 15 years ago, with the Cosmic Background Explorer made the map on the upper right, which basically showed us that there were large scale fluctuations, and actually fluctuations on several scales. You can kind of see that.
