“The Mars 2020 rover mission is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The Mars 2020 mission addresses high-priority science goals for Mars exploration, including key questions about the potential for life on Mars. The mission takes the next step by not only seeking signs of habitable conditions on Mars in the ancient past, but also searching for signs of past microbial life itself. The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a “cache” on the surface of Mars. A future mission could potentially return these samples to Earth. That would help scientists study the samples in laboratories with special room-sized equipment that would be too large to take to Mars. The mission also provides opportunities to gather knowledge and demonstrate technologies that address the challenges of future human expeditions to Mars. These include testing a method for producing oxygen from the Martian atmosphere, identifying other resources (such as subsurface water), improving landing techniques, and characterizing weather, dust, and other potential environmental conditions that could affect future astronauts living and working on Mars.”

“NASA’s InSight has been busy. After landing on the Red Planet, the mission sent home pictures and sound, then placed its first instrument on the planet’s surface. Plus, find out what the Curiosity rover has been up to. “

“InSight is a robotic lander designed to study the interior of the planet Mars. The mission launched on 5 May 2018 and is expected to land on the surface of Mars at Elysium Planitia on 26 November 2018, where it will deploy a seismometer and burrow a heat probe. It will also perform a radio science experiment to study the internal structure of Mars.

The mission is managed by the Jet Propulsion Laboratory for NASA. The lander was manufactured by Lockheed Martin Space Systems and was originally planned for launch in March 2016. The name is a backronym for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport.

InSight’s objective is to place a stationary lander equipped with a seismometer called SEIS produced by the French space agency CNES, and measure heat transfer with a heat probe called HP3 produced by the German space agency DLR to study the planet’s early geological evolution. This could bring new understanding of the Solar System’s terrestrial planets — Mercury, Venus, Earth, Mars — and the Earth’s Moon. By reusing technology from the Mars Phoenix lander, which successfully landed on Mars in 2008, it is expected that the cost and risk will be reduced.”

“Less than 2 minutes after the launch of a 58-foot-tall (17.7-meter) Black Brant IX sounding rocket, a payload separated and began its dive back through Earth’s atmosphere. When onboard sensors determined the payload had reached the appropriate height and Mach number (38 kilometers altitude, Mach 1.8), the payload deployed a parachute. Within four-tenths of a second, the 180-pound parachute billowed out from being a solid cylinder to being fully inflated. It was the fastest inflation in history of a parachute this size and created a peak load of almost 70,000 pounds of force.”

“As of October 2016, all methods of landing on Mars have required an aeroshell and parachute sequence for Mars atmospheric entry and descent, but after that there are three choices. A stationary lander can drop from the parachute back shell and ride retrorockets all the way down, but a rover cannot be burdened with rockets that serve no purpose after touchdown.

One method (for lighter rovers) is to enclose the rover in a tetrahedronal structure which in turn is enclosed in airbags. After the aeroshell drops off, the tetrahedron is lowered clear of the parachute back shell on a lanyard so that the airbags can inflate. Retrorockets on the back shell can slow descent. When it nears the ground, the tetrahedron is released to drop to the ground, using the airbags as shock absorbers. When it has come to rest, the tetrahedron opens to expose the rover.

If a rover is too heavy to use airbags, the retrorockets can be mounted on a sky crane. The sky crane drops from the parachute back shell and, as it nears the ground, the rover is lowered on a lanyard. When the rover touches ground, it cuts the lanyard so that the sky crane (with its rockets still firing) will crash well away from the rover.

For landers that are even heavier than the Curiosity rover (which required a 4.5 meter (15 feet) diameter aeroshell), engineers are developing a combination rigid-inflatable Low-Density Supersonic Decelerator that could be 8 meters (28 feet) in diameter. It would have to be accompanied by a proportionately larger parachute.”
