July 1965: Mariner 4 Closest Approach to Mars On 15 July 1965, Mariner 4 made its closest approach to Mars, detected the weak Martian radiation belt, and captured the first images of another planet from deep space. Probes have been active on Mars continuously since 1997; at times, more than ten probes have simultaneously operated in orbit or on the surface. Mars is an often proposed target for future human exploration missions, though no such mission is planned yet. On July 4, 1997, a new era of continuous robotic scientific exploration of Mars began, with at least one spacecraft operating at all times, either on the surface or in orbit around the planet. Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated a small rover about 100 m clockwise around the lander, and collected data from three science instruments and ten technology experiments. On September 12, 1997, the Mars Global Surveyor (MGS) entered an elliptical orbit around Mars, beginning a 20-year period of continuous robotic scientific exploration at the Red Planet. There are seven orbiters surveying the planet: Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter, MAVEN, the Trace Gas Orbiter, the Hope Mars Mission, and the Tianwen-1 orbiter, which have contributed massive amounts of information about Mars. As the Mars Pathfinder spacecraft approached its destination on July 4, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years. Even the mission team anxiously awaiting confirmation that the spacecraft survived its innovative, bouncy landing could not anticipate the magnitude of the pivot about to shape the Space Age. After hurtling through millions of miles of space since its December launch, Pathfinder arrived on Mars less than a second from its projected landing time. It landed about 30 miles (50 kilometers) from the center of the elliptical zone on the surface where the NASA team had been aiming. On July 4, 1997, the lander of the Mars Pathfinder mission made a soft landing in Ares Valley. It delivered a stationary platform to the Red Planet, as well as the first-ever rover Sojourner. In the 20 years since Pathfinder's touchdown, eight other NASA landers and orbiters have arrived successfully, and not a day has passed without the United States having at least one active robot on Mars or in orbit around Mars. On Friday, July 4th, NASA’s Pathfinder spacecraft is due to plunge into the thin red Martian sky, the first U.S. visitor to the planet next door since the Viking missions 21 years ago. NASA is releasing these images to commemorate the second anniversary of the Mars Pathfinder landing. The lander and its rover, Sojourner, touched down on the Red Planet's rolling hills on July 4, 1997, embarking on an historic three-month mission to gather information on the planet's atmosphere, climate, and geology. NASA’s Mars Pathfinder probe dropped to the surface of Mars for an airbag-cushioned landing 20 years ago Tuesday, bouncing 15 times across an ancient flood plain before deploying a mobile robot Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun. This is another similarity with Earth, which has an axial tilt of 23.4 degrees. Like Earth, Mars has distinct seasons, but they last longer than seasons here on Earth since Mars takes longer to orbit the Sun (because it's farther away). Launched on December 4, 1996 by NASA aboard a Delta II booster a month after the Mars Global Surveyor was launched, it landed on July 4, 1997 on Mars's Ares Vallis, in a region called Chryse Planitia in the Oxia Palus quadrangle. In fact, JPL designed, built, and operated all five of the successful Mars rovers. Since 1997, JPL-managed spacecraft have been exploring continuously on the ground and in the skies above Mars. What We Learn By Exploring Mars That reddish planet in our nighttime skies has long intrigued brilliant science fiction writers and enthusiasts. Following the successful landing of the Mars Pathfinder lander and rover on July 4, 1997, Mars Global Surveyor is the first in a multi-year series of missions called the Mars Surveyor program that will lead to eventual human expeditions to the red planet. Mars is the fourth planet from the Sun, and the seventh largest. It’s the only planet we know of inhabited entirely by robots.

Upon arrival at Mars on July 4, 1997, Mars Pathfinder began its four-minute entry, descent, and landing sequence, the first U.S. spacecraft to use the approach of using landing air bags. The first spacecraft to visit Mars was Mariner 4 in 1965. Several others followed including Mars 2, the first spacecraft to land on Mars and the two Viking landers in 1976. Ending a long 20 year hiatus, Mars Pathfinder landed successfully on Mars on 1997 July 4. In 2004 the Mars Expedition Rovers "Spirit" and "Opportunity" landed on Mars sending back geologic data and many pictures; they are
