Researchers using NASA's Mars Reconnaissance Orbiter have found possible flowing water on Mars. A team using the HiRISE camera aboard the Mars orbiter have tracked seasonal changes to determine that finger-like features appear and extend down some Martian slopes during the warmest months of the Mars year. The features fade during the winter, and return during the next spring.  Repeated observations have tracked the seasonal changes in these recurring features on several steep slopes in...

Science Journal Has Embargoed Details Until 2 p.m. EDT on Aug. 4 NASA will host a news briefing on Thursday, Aug. 4, at 2 p.m. EDT about a significant new Mars science finding. The briefing will be held in the NASA Headquarters James E. Webb Auditorium, 300 E St. SW in Washington. The new finding is based on observations from NASA's Mars Reconnaissance Orbiter (MRO), which has been orbiting the Red Planet since 2006. MRO is managed by the Jet Propulsion Laboratory, a division of the...

NASA scientists are seeing new evidence that suggests traces of water on Mars are under a thin varnish of iron oxide, or rust, similar to conditions found on desert rocks in California's Mojave Desert. Mars could be spotted with many more patches of carbonates than originally suspected. Carbonates are minerals that form readily in large bodies of water and can point to a planet's wet history. Although only a few small outcrops of carbonates have been detected on Mars, scientists believe many...

MESSENGER Co-Investigator Scott Murchie, of the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., will be awarded the NASA Distinguished Public Service Medal, the highest honor that NASA bestows to an individual working outside the government. The award is granted only to individuals whose singular accomplishments contributed substantially to the NASA mission. Murchie is receiving the honor in recognition of his leadership of the Compact Reconnaissance Imaging...

Southern California's high desert has been a stand-in for Mars for NASA technology testing many times over the years. And so it is again, in a series of flights by an F/A-18 aircraft to test the landing radar for NASA's Mars Science Laboratory mission. The flight profile is designed to have the F/A-18 climb to 40,000 feet (about 12,000 meters). From there, it makes a series of subsonic, stair-step dives at angles of 40 to 90 degrees to simulate what the Mars radar will see while the...

Two digital color cameras riding high on the mast of NASA's next Mars rover will complement each other in showing the surface of Mars in exquisite detail. They are the left and right eyes of the Mast Camera, or Mastcam, instrument on the Curiosity rover of NASA's Mars Science Laboratory mission, launching in late 2011. The right-eye Mastcam looks through a telephoto lens, revealing details near or far with about three-fold better resolution than any previous landscape-viewing camera on...

See it at JPL Open House May 14 and 15 The Spacecraft Assembly Facility of NASA's Jet Propulsion Laboratory in Pasadena, Calif., was constructed in 1961 to support NASA's Ranger and Mariner missions to the moon, Venus and Mars. America had entered the Space Age just three years earlier, with the launch of the JPL-built Explorer 1 spacecraft. The Spacecraft Assembly Facility, also known as JPL Building 179, originally had just one high bay, the large chamber now named High Bay 1. It is about...

WASHINGTON, April 21, 2011 /PRNewswire-USNewswire/ -- NASA's Mars Reconnaissance Orbiter (MRO) has discovered the total amount of atmosphere on Mars changes dramatically as the tilt of the planet's axis varies. This process can affect the stability of liquid water if it exists on the Martian surface and increase the frequency and severity of Martian dust storms. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Researchers using MRO's ground-penetrating radar identified a...

NASA's versatile Mars Reconnaissance Orbiter, which began orbiting Mars five years ago today, March 10, has radically expanded our knowledge of the Red Planet and is now working overtime. The mission has provided copious information about ancient environments, ice-age-scale climate cycles and present-day changes on Mars. The orbiter observes Mars' surface, subsurface and atmosphere in unprecedented detail. The spacecraft's large solar panels and dish antenna have enabled it to transmit more...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
