On August 27, 2012, the Mars Rover Curiosity beamed back images of Gale Crater’s 3-mile high Mount Sharp, whose layered terrain may reveal further details of Mars’ geological history. Curiosity will eventually travel to Mount Sharp to analyze its rocks by collecting samples. Curiosity also broadcasted a voice recording of NASA administrator Charles Bodin congratulating the Mars Rover team on the successful August 5 landing. In the recording, Bodin said: “This is an extraordinary achievement. Landing a rover on Mars is not easy. Others have tried; only America has fully succeeded.” Mars’ Sample Analysis at Mars instrument (SAM), which passed tests, is in working order and will digest and analyze rocks. In addition, Curiosity will drive to depressions on Mars’ surface where the spacecraft’s landing engines left their mark. These holes will allow Curiosity to image Mars’ interior without drilling. In the next few days, Curiosity will head over 1,300 feet to its first drilling target, Glenelg.
On August 28, 2012, Curiosity transmitted to Earth (JPL in La Cañada Flintridge) artist will.i.am’s new song titled “Reach for the Stars.” The first music to be broadcasted from another planet, will.i.am’s song traveled 700 million miles to Earth. Will.i.am is an advocator of science and math education. NASA had broadcasted the Beatles’ song “Across the Universe” on the group’s 40th anniversary in 2008.
Mars Science Laboratory/ Curiosity sure is gaining ground in Mars research. What will it discover? What mysteries will Curiosity uncover? Was Mars once habitable for microorganisms? Perhaps only time will tell.

Mars, the Red Planet: Home of Curiosity and soon-to-be InSight?
10 days after Curiosity’s successful landing, the U.S. space embassy ordered another Mars mission in 2016 to examine below Mars’ surface. Researchers want to examine Mars’ seismic activities— to see if Mars has fault lines like Earth and what of “marsquakes” are there. The InSight Mission (Interior exploration using Seismic Investigations, Geodesy and Heat Transport) will launch in March 2016. The budget for the mission is $425 million, not including the cost of the launch vehicle. JPL and the team of engineers and scientists who built Curiosity will build InSight, set to be Curiosity’s companion. InSight will harbor a French built seismometer and solar panels. One of InSight’s four instruments, the Heat Flow and Physical Properties (HP3), will crack through the surface using a 14-inch “hollowed-out electromechanically- festooned stake” called the Tractor Mole. The Mole will descend 16 feet below the planet’s surface. Its thermal senors will also measure the temperature of Mars’ interior to learn about the planet’s thermal temperature. The mission of InSight will be to analyze Mars’ core to learn about the early formation of rocky bodies like Earth. InSight will determine the core’s size and composition and whether it’s solid or liquid. It will take InSight 6 months to reach Mars (will land in September 2016) and a full Martian year (680 Earth days) to gather data.

Curiosity uses its laser for the first time to zap a rock “Coronation.” What a fitting name! Curiosity is the crowning achievement of NASA/ JPL for missions in Mars exploration in recent years. Curiosity’s ChemCam, or Chemistry and Camera equipment hit the fist-sized “Coronation” with 30 pulses (Each pulse = more than 1 million watts in five one-billionths of a second!) of laser in a 10-second period. By exciting atoms in “Coronation” into a glowing plasma, ChemCam can capture the light with a telescope and analyze the rock with three spectrometers to determine its elemental composition. If the composition changed as the pulses progressed, then dust or other surface material covered the rock. ChemCam uses laser-induced breakdown spectroscopy, which can determine the composition of targets in extreme environments, such as on sea-floor, and is used in experimental applications in cancer detection and environmental monitoring. For its 2-year mission, Curiosity will continue to use its spectacular 10 instruments to determine whether Gale crater ever offered suitable environmental conditions for life.

Curiosity/ Mars Science Laboratory has successfully landed on the Red Planet on August 5, 2012 at 10:31 PM (Pacific Time). JPL engineers gave the landing a “perfect 10”! The Mars rover escaped the 7 minutes of terror and will continue its 2-year mission. This revolutionary success marks the first time since the 1970s (Viking probes) that NASA sent a mission for astrobiology. Curiosity will analyze samples on Mars to determine if Mars has ever been habitable for life forms. The $2.5 billion project offset the recent loss of the 30-year space shuttle program. The rover sent its first three images of Mars, sending JPL into an uproar.

Curiosity: A model at the Discovery Science Center
The Mars Rover Curiosity will land on the Red Planet on August 5, 2012 (Pacific Time).
A collaboration between JPL (Jet Propulsion Laboratory) and NASA, Mars Rover Curiosity (SUV), otherwise known as Mars Science Laboratory (MSL), has technology that succeeds its predecessors, Spirit and Opportunity (golf carts) and Sojourner (microwave). NASA launched Curiosity on November 26, 2011 at the Cape Canaveral Air Force Station. Curiosity is expected to land on August 5, 2012 on the Aeolis Palus region of the Gale crater. Curiosity‘s four objectives are: 1) determine whether Mars is suitable for life; 2) study Mars’ climate; 3) study Mars’ climate; 4) plan future human mission to Mars.
Weight: 2,000 lbs.
Length: >9.8 ft.
Distance Covered (per day): ~600 ft
Lifetime: >687 Earth days (1 Martian year)
Power: Radioisotope Thermoelectric Generator (RTG) – uses the decay of plutonium-238 to generate 2.5 kilowatt hours per day
Heat Rejection System: To keep Curiosity at optimal temperatures since temperatures on Mars vary dramatically (30°C to -127°C)
Computers: “Rover Compute Element” – tolerates extreme radiation from space; Inertial Measurement Unit (IMU) – rover navigation
Communications: X band transmitter – communicate directly with Earth; UHF Electra-Lite software defined radio – communicate with Mars orbiters
Mobility: 6 wheels in rocker-bogie suspension – serve as landing gear
Cameras: 1. MastCam – multiple spectra and true color imaging; 2. Mars Hand Lens Imager (MAHLI) – microscopic images of rock and soil; 3. MSL Descent Imager (MARDI) – color images to map the surrounding terrain and landing location
ChemCam: laser to vaporize samples up to 7 meters away for analysis, with the laser-induced breakdown spectroscopy (LIBS) and micro-imager (RMI)
Alpha-particle X-ray spectrometer (APXS): map the spectra of X-rays to elemental composition of samples
Chemistry and Mineralogy (CheMin): identify and quantify abundance of minerals on Mars
Sample Analysis at Mars (SAM): analyze organics and gases from atmospheric and solid samples
Dynamic Albedo of Neutrons (DAN): measure hydrogen, ice, and water at and near Martian surface
Rover Environmental Monitoring System (REMS): measure atmospheric pressure, humidity, wind currents and direction, air and ground temperature, UV levels
Hazard Avoidance Cameras (HazCams): use light to capture 3-D image to protect the rover from crashing
Navigation Cameras (Navcams): use visible light to capture 3-D images for navigation
EDL (Entry, Descent, Landing): also called the “7 minutes of Terror,” because any malfunction or any misstep means failure of the mission
Landing Sequence: “6 vehicles, 76 pyrotechnic devices, 500,000 lines of code, zero margin of error”; from 13,000 miles an hour to 0 miles and hour; 1,600 degrees upon entry
Mar’s atmosphere is 100 times thinner than Earth’s so it is harder for MSL to slow down
Guided Entry: control the craft to approximate landing site region
Parachute Descent: supersonic parachute (can withstand 65,000 lbs of force but only weighs 100 lbs.) deploys at 10 km altitude
Powered Descent: cut parachute off and rocket thrusters (Mars Lander Engine, MLE) extend out and slow the descent
Sky Crane: lower the rover with a 21-foot tether wheels down onto the Martian crater to prevent the rockets from making dust clouds; the bridle is cut and the rock thrusters fly away to a safe distance
Each wheel on Curiosity has a specific traction pattern that is Morse code for “JPL”
It takes 13 minutes and 46 seconds to relay signals from Earth to Curiosity
