Re: New 2020 Mars Rover based on MSL

Another step closer to going to mars
Lockheed Martin delivers Mars 2020 rover aeroshell to launch site

http://www.spxdaily.com/images-hg/lockh … ker-hg.jpg

The backshell and heat shield aeroshell that will encapsulate and protect the needed to send the Mars 2020 rover to Mars. The large mass and unique entry trajectory profile that could create external temperatures up to 3,800 degrees Fahrenheit, the heat shield uses a tiled Phenolic Impregnated Carbon Ablator (PICA) thermal protection system instead of the Mars heritage Super Lightweight Ablator (SLA) 561V.

"Even though we have the experience of building the nearly identical aeroshell for the Curiosity Rover, the almost 15-foot diameter composite structure. Curiosity mission, this is the largest aeroshell/heat shield ever built for a planetary mission at 4.5 meters (nearly 15 feet) in diameter. In contrast, the aeroshell/heat shield of the InSight lander measured 8.6 feet and Apollo capsule heat shields measured just less than 13 feet.

We will need bigger if we are going to mars with any mass that matters.

Two rovers to toll on Mars Again in 2020

Curiosity won't be NASA's only active Mars rover for much longer. Next summer, Mars 2020 will be headed for the Red Planet. While the newest rover borrows from Curiosity's design, they aren't twins: Built and managed by NASA's Jet Propulsion Laboratory in Pasadena, California, each has its own role in the ongoing exploration of Mars and the search for ancient life.

Re: New 2020 Mars Rover based on MSL

science is pushing the detective edge to discover what happened to mars in the past which made it go a different direct when compared to earth.
Developing a technique to study past Martian climate

We have been testing and sampling the geochemistry of Mars with a few rovers but what is that next step?

Lab research will focus on creating silica minerals in the laboratory to discover how they form in subzero temperatures.

Re: New 2020 Mars Rover based on MSL

The conversion of air which can be processed for the co2 there is an energy required to process a given volume at the parts per million rate with in the volume of air process which will give us a net mass of co2 at gas level and then at a liquid volume pressure for temperature.

That said how do we compute some of this?

How much volume does 1 kg of CO2 occupy at room temperature and standard pressure?

CO2 has a molecular weight of 44 g/mol
1 kg CO2 = 1000 g × (1 mol/44 g) = 22.7 mol CO2

V=nRT/P, V=(22.7)(0.0821)(300)/1 = 559 L CO2 at 27°C (300K), 1 atm

This is a little more than half a cubic meter approximately equal to the volume of two bathtubs or the trunk of a large car.

So using the formular we need to suck in since carbon is 12 and oxygen is 16 for a mole mass of 12+32 = 44

1 kg o2 = 1000 g x (1 mol/32 g) = 31.25 mol o2

https://techport.nasa.gov/view/33080
Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE)

producing at least 6 grams of O2 per hour

A scroll pump delivers up to 50 g/hour of atmosphere to the SOXE subsystem.

The Mars atmosphere is processed as follows: the SOXE is warmed to 800 C; the pump is started and the filtered air will flow continuously at >1 torr to the SOXE. The O2 and CO are separated and the flow rate is measured.

Mars 2020 is a Mars rover mission by NASA's Mars Exploration Program with a planned launch on 17 July 2020, and touch down in Jezero crater on Mars on 18 February 2021.

Re: New 2020 Mars Rover based on MSL

I for one am a little tired of waiting for Nasa to take its foot out of ,,,,,,
Mars 2020 rover to seek ancient life, prepare human missions

"It's designed to seek the signs of life, so we're carrying a number of different instruments that will help us understand the geological and chemical context on the surface of Mars," devices on board the rover are 23 cameras, two "ears" that will allow it to listen to Martian winds, and lasers used for chemical analysis. "What we're looking for is ancient microbial life -- we're talking about billions of years ago on Mars, when the planet was much more Earth-like," when the Red Planet had warm surface water, a thicker atmosphere and a magnetic force around it, he explained.
Mars 2020 will land in a long dried-up delta called Jezero. The site, selected after years of scientific debate, is a crater that was once a 500-yard-deep lake.  It was formerly connected to a network of rivers that flowed some 3.5 to 3.9 billion years ago. The crater measures just under 30 miles across, and experts hope it may have preserved ancient organic molecules.

Re: New 2020 Mars Rover based on MSL

NASA lists nine potential names suggested by kids for its next Mars rover: Vote for your favorite

NASA and an army of nearly 4,700 volunteer judges have selected nine potential names for a rover that’s due to be launched to Mars in July, and you have just six days to cast an online vote for your favorite name.
NASA kicked off the “Name the Rover” essay contest last August, and more than 28,000 name suggestions and accompanying essays were received from students in kindergarten through 12th grade. It took weeks for the judges to narrow down the field, first to 155 semifinalists, and then to the nine finalists — three for grades K-4, three for grades 5-8, and three for grades 9-12.
The K-4 suggestions are Endurance (from Virginia’s Oliver Jacobs), Tenacity (from Pennsylvania’s Eamon Reilly) and Promise (from Massachusetts’ Amira Shanshiry). In the 5-8 category, the names are Perseverance (from Virginia’s Alexander Mather), Vision (from Mississippi’s Hadley Green) and Clarity (from California’s Nora Benitez). In the 9-12 category, you can pick between Ingenuity (from Alabama’s Vaneeza Rupani), Fortitude (from Oklahoma’s Anthony Yoon) and Courage (from Louisiana’s Tori Gray).
The online voting booth is open until 9 p.m. PT Jan. 27. Poll results will be considered, along with other factors, and the winning name will be announced in early March. The student whose name is selected will receive an invitation to watch this summer’s launch from Cape Canaveral Air Force Station in Florida.

Many also get to have there name sent to mars digitally as well....
