On March 1, 1966 the Venera 3 Soviet space probe crash-landed on Venus, becoming the first spacecraft to reach the surface of another planet. Its sister craft Venera 2 had failed due to overheating shortly before completing its flyby mission. ... The first successful landing on Venus was by Venera 7 on December 15, 1970.

Nasas Mars rover lands safely on the red planet. After a sevenmonth voyage from Earth the US space agency's probe Spirit landed safely on the surface of Mars. Within hours of arriving it sent back its first images of the red planet's barren rockstrewn landscape.

Venus Inside and On Top The planet is a little smaller than Earth, and is similar to Earth inside. We can't see the surface of Venus from Earth, because it is covered with thick clouds. However, space missions to Venus have shown us that its surface is covered with craters, volcanoes, mountains, and big lava plains.

The rover sent its last status on 10 June 2018 when a global 2018 Mars dust storm blocked the sunlight needed to recharge its batteries. After hundreds of attempts to reactivate the rover, NASA declared the mission complete on February 13, 2019.

Why is the atmosphere of Venus very dense but the atmosphere of Mars is very thin? The atmosphere of Venus and Mars has a carbon dioxide mostly. The reason is that neither of these planets has liquid water on their surfaces to remove the CO2 from the atmosphere.

Relive the nail-biting terror and joy as NASA's Curiosity rover successfully landed on Mars the evening of Aug. 5 PDT (morning of Aug. 6 EDT). See and hear the team inside JPL mission control along with a visualization of the spacecraft's entry, descent and landing.

While cats (particularly those of Ulthar) are said to be able to jump to the Moon, Mars is presumably a leap too far, thus there are no cats, living or dead on the red planet. Michael Georgiades, Amateur science enthusiast.

One of the great exploration stories of our time is officially over. NASA declared its Opportunity Mars rover dead today (Feb. 13), more than eight months after the solar-powered robot went silent during a raging dust storm on the Red Planet — and a day after the final calls to wake Oppy up went unanswered.

There have also been studies for a possible human mission to Mars, including a landing, but none have been attempted. The most recent landing took place on 26 November 2018 by the NASA probe InSight.

Quick Summary: Mars is relatively small, having only about 10% the mass of the Earth. Mars has an atmosphere made up mostly of Carbon Dioxide but its pressure is only 1% of the Earth's atmospheric pressure. Thus Mars has 10,000 times less Carbon Dioxide in its atmosphere than Venus.

Venus' crust is mostly basalt, and is estimated to be 6 to 12 miles (10 to 20 km) thick, on average. Venus is the hottest planet in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.

Mars lost its atmosphere and dried up to become cold windy and dead. With respect the goldilocks 'bed testing' model of planetary tectonics: Mars is too hard (thick lithosphere), Venus is too soft (thin lithosphere), but the Earth is just right (30- 150 km thick lithosphere).

That's a total time of 97 days; just over 3 months. The first successful Venus flyby was NASA's Mariner 2. This spacecraft was launched on August 8th, 1962 and made a successful flyby on December 14, 1962. So that calculates to 110 days from launch to arrival at Venus.

Physical characteristics. Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth. It is similar to Earth in size and mass, and is often described as Earth's "sister" or "twin".

What are the Mars rovers? Over the years, NASA has sent four robotic vehicles, called rovers, to Mars--and NASA plans to send another soon. In total, the four rovers that have already gone to Mars are: Sojourner, Spirit and Opportunity, and Curiosity. The Perseverance rover will be heading to the Red Planet soon.

The shortest time a spacecraft has taken to get to Venus from Earth is 109 days, or 3.5 months. The longest journey took 198 days or 6.5 months. Most journeys take between 120 and 130 days which is about 4 months.
