Title: Spacecraft at Mars prepare for new kid on the block
Post by: mickw on Mar 01, 2008, 12:30:14
Three Mars spacecraft are adjusting their orbits to be over the right place at the right time to listen to NASA's Phoenix Mars Lander as it enters the Martian atmosphere on May 25.
Every landing on Mars is difficult. Having three orbiters track Phoenix as it streaks through Mars' atmosphere will set a new standard for coverage of critical events during a robotic landing. The data stream from Phoenix will be relayed to Earth throughout the spacecraft's entry, descent and landing events. If all goes well, the flow of information will continue for one minute after touchdown.

NASA has adjusted the flight path of its Phoenix Mars Lander, en route to a planned touch-down on the Red Planet on 25 May, on its mission to explore the body's Arctic plain.

The agency has "conditionally approved" a roughly 62 mile by 12 mile (100km by 20km) "landing ellipse" in an area dubbed "Green Valley", which lies at approximately 68 degrees N, 233 degrees E, having scoured High Resolution Imaging Science Experiment (HiRISE) images of the area for potential hazards.

Title: Phoenix Lander Takes Aim at Martian Arctic
Post by: mickw on May 01, 2008, 18:52:36
NASA's Mars-bound Phoenix spacecraft is gearing up for a landmark landing near the martian north pole this month to find out whether the region could have once supported microbial life.
Phoenix is on course for a planned May 25 touchdown in the martian arctic that, if successful, will mark the first powered landing on Mars since NASA's hefty Viking 2 lander set down in 1976. But first, the probe is expected to fire its thrusters several times in the next few weeks to fine-tune its flight path.

"It's scary how smooth it's been," said Barry Goldstein, Phoenix project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "The vehicle has just been behaving beautifully."

Title: NASA bites nails over Phoenix landing
Post by: Rick on May 14, 2008, 10:59:39
NASA's Phoenix Mars Lander is on its final approach for a slated touch-down on the Red Planet's Arctic region on 25 May amid a certain amount of nail-biting as to whether it will survive the landing.

Ed Weiler, associate administrator for NASA's Science Mission Directorate, admitted yesterday: "This is not a trip to grandma's house. Putting a spacecraft safely on Mars is hard and risky. Internationally, fewer than half the attempts have succeeded."

Scientists are preparing for "seven minutes of terror" as a Nasa spacecraft makes a nail-biting descent to the surface of Mars.

The Phoenix lander will begin its plunge through the Martian atmosphere on 25 May (GMT) as it attempts to land in the planet's polar north.

The craft needs to perform a series of challenging manoeuvres along the way.

It then begins a three-month mission to investigate Mars' geological history and potential habitability.

NASA's Phoenix Mars Lander is looking good for a Sunday touch-down on the Red Planet, with all systems "nominal and stable", according to the agency.

Phoenix is, however, currently "closing in on the scariest seven minutes of the mission" when it must decelerate from 13,000mph (21,000km/h) to just 5mph (8km/h) using a combination of "superheated friction with the atmosphere, a strong parachute and a set of pulsing retrorockets" to achieve a gentle landing.

Nasa says its Phoenix spacecraft is in good health after making the first successful landing in the north polar region of Mars.

Images sent back show a flat valley floor with polygonal features that give the ground a "paved" appearance.

These are believed to be a sign of the water-ice that lies just beneath the surface at these high latitudes.

The ice should be within reach of the probe's 2.35m-long robotic arm, which is due to be deployed this week.

Title: Phoenix prepares to flex its muscles
Post by: Rick on May 29, 2008, 10:29:35
NASA is preparing to flex the robotic arm on its Phoenix lander following a technical glitch which provoked a temporary comms breakdown between the spacecraft and the Mars Reconnaissance Orbiter, which relays commands to Phoenix and dispatches information from the Martian surface back to Earth.

NASA explains: "The UHF radio system used by the orbiter to communicate with the lander had gone into a standby mode earlier Tuesday for a still undetermined cause. This prevented sending Phoenix any new commands from Earth on Tuesday. Instead, the lander carried out a backup set of activity commands that had been sent Monday."

Nasa's Mars lander Phoenix has unstowed its robotic arm - the key tool in its mission to test the red planet's soil for the building blocks of life.

The 2.35m (7.7ft)-long titanium and aluminium extension will dig below the Martian topsoil to the water-ice which is thought to lie just beneath.

The next step will be to test the arm's four joints to be sure it is in working order before digging into the soil.

Title: Phoenix chokes on 'clumpy' Martian soil
Post by: Rick on Jun 10, 2008, 13:09:43
NASA's Phoenix Mars lander has hit a glitch in its first attempt to sample Martian soil - the Red Planet's surface may have proved too "clumpy" for one oven in the Thermal and Evolved-Gas Analyzer (TEGA).

Phoenix recently scooped up a cup-sized sample of material for the "high-temperature furnace and mass spectrometer" TEGA, which features screened openings so that only particles less than 1mm can pass into the device's miniature ovens. Once inside, they're slowly heated up during a week's analysis to determine the soil's water and mineral content.

The Thermal and Evolved-Gas Analyzer (TEGA) aboard NASA's Phoenix Mars lander finally has an ovenful of dirt for anlaysis, following various attempts to shake the "clumpy" Martian soil into the instrument.

The "high-temperature furnace and mass spectrometer" TEGA packs eight miniature ovens, each protected by a filter screen to prevent the entry of particles larger than 1mm. However, the Red Planet's surface resolutely refused to play ball when NASA tried to fill oven number four last Friday, and the infrared beam designed to detect particles falling into the oven showed no activity.

The Phoenix spacecraft on Mars is finally getting to grips with the clumpy soil at its landing location.

Early efforts to grab samples for study in the onboard lab had been frustrated by the cloddy nature of the ground.

But by shaking the scoop bucket on the end of its robotic arm, Phoenix now has a very effective technique to deliver fine samples to test instruments.

Mission scientists report that Phoenix has made a very delicate dusting of material across a microscope.

Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it.

"It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing over the course of a few days, that is perfect evidence that it's ice. There had been some question whether the bright material was salt. Salt can't do that."

Engineers said a short circuit that occurred last month in one of its test ovens designed to shake and bake miniscule soil samples could happen again when the instrument is turned on.

"Since there is no way to assess the probability of another short circuit occurring, we are taking the most conservative approach and treating the next sample ... as possibly our last," the NASA mission's chief scientist, Peter Smith of the University of Arizona in Tucson, said in a statement Wednesday

Nasa's Phoenix spacecraft will try a new way of getting icy Martian soil into its onboard oven for testing, after it ran into problems last week.

The soil has proven to be very sticky, hampering attempts to carry out tests.

On its previous attempt, most of the soil sample collected by Phoenix's robotic arm got stuck in the scoop and would not fall into the oven.

During its stint in the Martian Arctic, NASA's Phoenix Mars lander made an impressive array of measurements and discoveries that will help fine-tune scientists' understanding of the chemistry and environment of the red planet.

Perhaps no discovery was more surprising than the detection of an odd type of salt that Phoenix scientists think could have an important impact on the Martian water cycle and the planet's ability to support life.

In a set of papers presented last week at the 40th Lunar and Planetary Science Conference (LPSC) in The Woodlands, Texas, several Phoenix team members put forth their ideas on how the class of salts, called perchlorates, might affect Mars' water cycle; how it might boost or inhibit potential Martian life; how it might form a sludge underneath Mars' polar cap, lubricating them and allowing them to flow, as glaciers do on Earth; and how the salt even got there in the first place.

Title: Nasa check for 'unlikely' survival of Mars lander

Nasa's Mars Odyssey orbiter is set to listen for possible radio transmissions from the Phoenix Mars lander, to check if it has survived the Martian winter.

The agency said that communication from the lander was "extremely unlikely".

Phoenix's last communication was on 2 November 2008, after it completed its study of an arctic Martian site.

Since then, this landing site has gone through autumn, winter and part of spring, and Phoenix was not designed to survive such temperature extremes.

Title: NASA Declares Mars Lander Broken and Dead
Post by: mickw on May 25, 2010, 08:35:11
NASA's long-dormant Phoenix Mars Lander is broken and officially down for the count, with new images taken by an orbiting probe showing severe damage to the spacecraft's solar panels due to the harsh Martian winter.

Repeated attempts by NASA in recent months to reestablish contact with Phoenix following its winter hibernation were unsuccessful, with no peeps coming from the lander
