Ready for a return to the moon? NASA’s Lunar Reconnaissance Orbiter (LRO) will collect information about the moon’s poles, measure radiation, and check out potential sites for an eventual human return to the moon’s surface in 2020–and it’s on track for a June 17th launch aboard an Atlas V rocket, according to Space.com.

NASA is launching the orbiter in tandem with the Lunar Crater Observation and Sensing Satellite (LCROSS), which will plunge into the surface of the moon in an attempt to find water ice. LRO’s seven instruments will help scientists compose high resolution,
three-dimensional maps of the lunar surface as well as complete a survey of the far ultraviolet spectrum, the report said. (Image credit: NASA)

Mars Probes Team Up to Un-Stick Stuck Rover

Mars_Rover.jpg

The Spirit Mars rover has been stuck in the red planet’s soil for a couple of weeks, so NASA is trying out a bunch of procedures–some involving other Mars craft–in order to figure out how to best extract Spirit from its predicament.

The problem: one of Spirit’s wheels stalled out, and the other wheels dug themselves in part of the way. The trick is to avoid sinking the rover further to the point where the belly pan is touching the soil, according to Space.com.
The report said that initially the Mars project team was worried that the left-middle wheel had jammed, but a recent diagnostic test of the motor on May 16th proved that its electrical resistance was within normal operating range, indicating that the motor is probably fine.

You Can Build Your Own Hubble Space Telescope

hubble-model.jpgThe Hubble Space Telescope has certainly been in the news this past week. Astronauts from Shuttle Atlantis stopped by for a billion dollars worth of refurbishing, hopefully succeeding in giving Hubble another decade of exquisite observation. Though in-orbit repairs were anticipated and designed into Hubble’s physical structure this mission saw some work no one ever expected–and it looks like it worked!

It’s an incredibly dangerous job which few Gearlog readers would turn down. Imagine a chance to do some fix-it work while traveling at 17,000+ mph at 350 miles above the Earth’s surface. Wow!

Of course most of us will never get to Hubble, but you can build your own. There are instructions to roll-your-own at Hubblesite.org.

Make a scale model of NASA’s Hubble Space Telescope using easy-to-find supplies and our printable materials.

These models aren’t working telescopes – you can’t peer at the sky with them. But they can give you an up-close look at the telescope’s structure and a challenging project to engage your model-making skills.

Detailed instructions are available for models using PVC (low detail, average difficulty) and paper (two sets of plans including a highly detailed but very complex model). Though I am not personally licensed for powertools, a more coordinated builder should be able to take the detailed instructions and build a model of true beauty. It’s the next best thing to being there.

Hubble is Released Into Orbit

And that’s a wrap: Space shuttle Atlantis crew member Megan McArthur used the shuttle’s robotic arm to release the Hubble Space Telescope into orbit at 8:57 a.m. EST Tuesday, CNN reports. The mission marks the last time humans will touch the 19-year old telescope. Hubble has taken hundreds of thousands of high-resolution images–all free of the earth’s murky atmosphere.

“With soft separation burn, Atlantis now is slowly backing away from the telescope,” NASA said in a statement. “A jet firing will be performed in about a half-hour to increase Atlantis’ separation rate from the telescope, as the seven crew members bid farewell to Hubble for the final time.”
During the repair mission, NASA astronauts performed five spacewalks to install a new deep-space camera, a new spectrograph, new batteries, a guidance sensor, and insulation, and repaired the older main camera and an older spectrograph.

Rivers May Have Recently Flowed On Mars: Report

NASA_Mars_ScienceNow_Rivers.jpg

More space news, this time further out into the solar system: the two Mars rovers are still trucking along, but scientists here on Earth are working on a thorny problem related to the red planet.

New research suggests that water may have flowed over Mars’ surface in at least one place over the past billion years–relatively “recently,” since the planet has been around for about the same 4.5 billion years as our own–giving more credence to the idea that life may have once existed there, according to ScienceNOW.

A while back, the rovers confirmed that water covered the surface of Mars about four billion years ago, when it was much warmer. But now that the planet is cooler and drier, we’ve only found small bits of evidence here and there. That’s beginning to change, though.

Astronauts On Final Hubble Spacewalk

NASA_Hubble_Repair_Shuttle.jpg

Two NASA astronauts are on a spacewalk performing the last repairs to the Hubble, and will be the last two humans ever to touch the aging space telescope, according to Space.com.

Atlantis astronauts John Grunsfeld and Andrew Feustel are working in the shuttle cargo bay to add new batteries, insulation and a guidance sensor to the Hubble Space Telescope. Over the weekend, the crew ran into some minor trouble with a stuck bolt and a dead battery in one of the tools, so the repairs are slightly behind schedule.
Nonetheless, the new guidance sensor will help the telescope keep its camera steady and aid in tracking star positions and motions, according to the article. So far, the astronauts have installed a new deep-space camera and a new spectrograph, and have refurbished Hubble’s advanced camera and older spectrograph.
Finally, they’re also adding a special docking ring so a robotic spacecraft can help guide the Hubble many years from now into the Pacific Ocean when it is decommissioned. (Image credit: NASA)

Europeans Launch Two Space Telescopes

Two European space telescopes have lifted off atop an Ariane 5 rocket from the European Space Agency’s launch center in French Guiana on Thursday, according to MSNBC. The two telescopes will help astronomers learn more about the origins of the universe.

Herschel, an infared telescope, will study the earliest stages of star and galaxy development and search for the presence of water in outer space. Planck, meanwhile, is a microwave telescope that will study the radiation left behind by the Big Bang 13.7 billion years ago, the report said, in an attempt to learn more about dark matter and dark energy–both of which constitute over 90 percent of the material in space.
“Our previous images of the baby universe were like fuzzy snapshots–now we’ll have the cleanest, deepest and sharpest images ever made of the early universe,” Charles Lawrence, a NASA Planck project scientist, said in a Jet Propulsion Laboratory statement.
On both telescopes, liquid helium will cool the instruments to 459 degrees below zero Fahrenheit, or 0.3 Kelvin (for Herschel) and 0.1 Kelvin (for Planck), in order for both of them to work properly, the report said. Herschel will arrive in orbit in two months, and then four months later will begin its 3.5-year mission. Planck will also reach orbit in two months and start its 15-month mission one month later. The two missions together cost about $2.5 billion. (Image credit: ESA)

Space Shuttle Catches Hubble

NASA_Hubble.jpg

The space shuttle Atlantis has caught up with the orbiting Hubble Space Telescope 350 miles above Earth, and is now preparing for its robot arm to grab hold of the telescope at 3:54 PM EST, according to CNN. In order to do so, the astronauts must periodically fire the shuttle’s thrusters to line it up with the scope. Meanwhile, the Goddard Space Flight Center in Greenbelt, Maryland is ordering Hubble to stow its two high-gain antennas and close a door to shield the sensitive mirror and other gear, according to the report.


By the end of the procedure, the shuttle will come within 35 feet of the scope, grab hold onto it, and bring it into the shuttle’s cargo bay for repairs. This will be the fifth and final repair mission for the Hubble, which last saw service seven years ago–four years beyond the usual maintenance interval. Originally NASA had decided to EOL Hubble in 2004 after the Columbia disaster the year before, but public pressure and a comprehensive boost in shuttle safety procedures (like the one we saw yesterday) caused the agency to reconsider.

NASA Streaming Dangerous Shuttle Mission Live

Shuttle.jpgNASA’s latest shuttle launch is set for today at 2:01 PM EDT. The self-assessed “high risk” mission is an attempt to repair the Hubble telescope one final time.

According to the weather reports for Cape Canaveral, there’s a 90 percent chance of favorable launch conditions. The 11-day mission will include five spacewalks, at up to 7hours each.

“This will be the most challenging servicing mission that’s been faced by our astronauts in terms of the total amount of work,” said mission manager, Preston Burch. If the mission succeeds, it will add up to five years onto the life of the 19-year-old telescope.

NASA is running a live feed of the launch all day with commentary over on its official site.

Explore the Space Station and Mars Rover on Your PC

NASA_Microsoft_Mars_Rover.jpg

Want a first-hand, three-dimensional look at NASA’s International Space Station? NASA has unveiled an interactive, 3-D photographic collection of internal and external views of the ISS, plus a model of the next Mars rover, according to PhysOrg.com. NASA developed the interactive tours in tandem with the Microsoft Virtual Earth team, using hundreds of photographs along with Microsoft’s Photosynth photo imaging technology.

“The space station pictures are not simulations or graphic representations but actual images taken recently by astronauts while in orbit,” said Bill Gerstenmaier, associate administrator for Space Operations at NASA Headquarters in Washington, in the article. “Although you’re not flying 220 miles above the Earth at 17,500 miles an hour, it allows you to navigate and view amazing details of the real station as though you were there.”

Meanwhile, the Mars rover imagery offers a preview of
NASA’s Mars Science Laboratory, which is scheduled to launch in 2011. View NASA’s Photosynth collection at http://www.nasa.gov/photosynth or on Microsoft’s Virtual Earth Web site at: http://www.microsoft.com/virtualearth. (Unfortunately, it requires a Microsoft Silverlight install, but it’s well worth it.) NASA also created a scavenger hunt to go with the imagery, including objects like a space suit and a station crew patch; the agency will be posting clues on Facebook and Twitter. More info on the scavenger hunt can be found at http://www.nasa.gov/collaborate.
