Curiosity's First Week On Mars
Aug. 11, 2012 --
It has barely been a week on Mars and NASA's Mars Science Laboratory rover "Curiosity" is wowing us with stunning views from the Red Planet. After the incredibly successful entry, descent and landing (EDL) of the one-ton rover on Sunday night (Aug. 5 PDT), mission controllers at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., have been checking out the mission's instrumentation -- and all have returned a clean bill of health. Immediately after landing, the first thumbnail photos from the rover's "Hazard Avoidance Cameras" (or "Hazcams" for short) were received and since then it's been a barrage of high-resolution photographs from a mission that is captivating the world. Here are some of Discovery News' favorite views from mankind's newest and most ambitious mission to Mars...

A Parachute Opens Through some carefully timed choreography with NASA's Mars Reconnaissance Orbiter (MRO), scientists operating the High-Resolution Image Science Experiment (HiRISE) camera were able to catch a glimpse of Curiosity descending through the Martian atmosphere shortly after its parachute opened, minutes before landing.
Flying Saucers on Mars? In a wonderful irony, Curiosity's aeroshell -- the capsule the rover was encased inside during transit from Earth to Mars -- resembled a classic flying saucer. But this flying saucer didn't come from Mars, it was very terrestrial in origin. During the dramatic EDL -- dubbed the "7-minutes of terror" by mission scientists -- the spent heat shield was jettisoned, allowing Curiosity's Mars Descent Imager (MARDI) a first glimpse of the Martian surface. This photograph depicts the heat shield falling away, just before Curiosity (plus Sky Crane) detached from the backshell of the aeroshell and parachute.

Curiosity, the Litterbug In another wonderfully detailed image from the HiRISE camera aboard the MRO, all the components of Curiosity's entry into the Martian atmosphere could be surveyed. The rover, parachute, crash site of the Sky Crane and ditched heat shield are all accounted for in this view.

Mount Sharp Mount Sharp -- otherwise known as Aeolis Mons -- became an immediate feature in the early photographs Curiosity's Hazcams sent back to Earth. As a testament to the high accuracy attained during landing, the rover touched down less than one mile away from its intended landing zone, putting it very close to Mt. Sharp and a veritable science gold mine.
Curiosity's Shadow As mission controllers continued to check out Curiosity's 17 different cameras, they commanded the rover's mast-mounted Navigation Cameras (or Navcams) to take a snapshot of Curiosity's "head" with the sun behind the rover. The result was captivating -- the outline of Curiosity's blocky Chemcam system against a rocky ground.
The Deck Using the mast-mounted Navcam system, Curiosity was able to survey its "deck" -- a partial 360 degree view was beamed back in high-resolution.
Wait a Minute... What's That? During testing of Mars rover Curiosity's mast-mounted Navcams on the second day of operations (Sol 2), small pieces of debris could be seen littering the deck of the rover. Where did it come from? But most importantly, could it be a hazard to Curiosity's instrumentation? As it turned out, the small pieces of gravel were unexpected, but mission manager Mike Watkins isn't concerned about the debris affecting the mission. "Some of the instruments (could be vulnerable to debris), but all check out OK," Watkins said after Discovery News posed a question at the daily JPL press briefing.
First Color Photo The Mars Science Laboratory mission will be returning a lot of "firsts" from the red planet's surface, but this was the rover's first color photo from Mars. It's blurred because the dust-protecting lens cap is still attached to Curiosity's Mars Hand Lens Imager (MAHLI), in case you were wondering.
That's Mojave Desert! Well, it's not, but there are similarities. As more images were returned from Curiosity, a better view of Gale Crater slowly came into focus. When NASA unveiled the first two full-frame images of Gale, lead scientist John Grotzinger remarked: "You would really be forgiven for thinking that NASA was trying to pull a fast one on you and we actually put a rover out in the Mojave Desert and took a picture, a little LA smog coming in there."
Panoramas Although the first 360 degree panorama was composed of thumbnails, the detail was spectacular. Just imagine what a full-resolution version will look like!

The Mission Begins Now that Curiosity has landed and NASA is currently uploading new software to its computers to ready it for surface operations, we can look forward to seeing more mind-blowing imagery from a rover hell-bent on exposing Mars' secrets.

A private Mars colony project will do its best to avoid disturbing potential Red Planet life rather than aggressively hunt it down.
The Netherlands-based nonprofit Mars One, which opened its astronaut-selection process today (April 22), plans to land four people on the Red Planet in 2023 as the vanguard of a permanent human colony on the Red Planet, with new crews arriving every two years thereafter.
Human explorers and their trillions of microbes will doubtless contaminate whatever site is chosen for the settlement, Mars One officials said, so the organization will try to pick a place unlikely to host indigenous life. [Mars One: Colonizing the Red Planet (Gallery)]
"The most important thing is that you localize the pollution," Mars One CEO and co-founder Bas Lansdorp said during a press conference today. "So you make sure that humans don't go to places where there's the highest chance of finding life, to make sure that if there is life [on Mars], that it will remain preserved."
Mars One is working with experts to minimize the risks its colonization effort may pose to potential Red Planet lifeforms. For example, the group's advisory board includes John Rummel, who chairs the Committee on Space Research's Panel on Planetary Protection, Lansdorp said.
It may be tough to bring those risks down too much. While Mars One hasn't picked a precise location for its settlement yet, the organization is targeting a swath of the Red Planet between 40 and 45 degrees north latitude, Lansdorp said.
Sites within this band likely have enough of two critical resources — subsurface water (in the form of ice) and solar energy — to support a colony, he added. But underground water could also help sustain microbes, whose toughness and near ubiquity continue to amaze scientists, at least here on Earth.
It's unclear at the moment if Mars One — which will fund its ambitious settlement efforts primarily by staging a global reality-TV event around the entire process — will take a serious stab at finding signs of Red Planet life.
Mars One astronauts will not necessarily be scientists, after all. Anyone over the age of 18 is eligible to apply, with the selection committee prizing traits such as intelligence, resourcefulness, determination and psychological stability over academic background, officials said.
"Science is, of course, not the main focus of what we are doing," Lansdorp said. "The main focus is getting those humans there and making sure that they survive."
Crewmembers will take some scientific gear with them, he added, but Mars One officials won't dictate what the experiments should be.
"It's really up to them," Lansdorp said. "There will of course be a budget for equipment that they want to take for scientific research."
