NASA to Demonstrate Communications Via Laser Beam

By Lori Keesey
NASA

It currently takes 90 minutes to transmit high-resolution images from Mars, but NASA would like to dramatically reduce that time to just minutes. A new optical communications system that NASA plans to demonstrate in 2016 will lead the way and even allow the streaming of high-definition video from distances beyond the Moon.

This dramatically enhanced transmission speed will be demonstrated by the Laser Communications Relay Demonstration (LCRD), one of three projects selected by NASA’s Office of the Chief Technologist (OCT) for a trial run. To be developed by a team led by engineers at the NASA Goddard Space Flight Center in Greenbelt, Md., LCRD is expected to fly as a hosted payload on a commercial communications satellite developed by Space Systems/Loral, of Palo Alto, Calif.

UKSA PR — Earlier this month the latest Mars rover prototype developed by UK engineers demonstrated its autonomous navigation capability in a specially constructed mock-up of a Martian landscape – a ‘Mars yard’ – at Astrium’s Stevenage site.

With work on the robot’s Guidance, Navigation and Control (GNC) system now finalised, this was the first public test of a technology that truly puts this rover – nicknamed Bruno – in a class of its own. This new class of rover will be able to decide on its own course across the Red Planet’s uneven, boulder-strewn and gully-pitted surface, identifying hazards such as rocks, slopes and drops, and plotting out the most appropriate route to a given destination. The human controllers simply provide the coordinates of a target location; the rover works out how best to get there, and trundles off.

Video: Mars500 Crew Makes Other Worldly Pizza

Our brave marsonauts may face the most monotonous phase of their mission, but they’re not bored because they are not boring! Have a look at their inventive cookery to celebrate their one full year in the isolation!

In early June the Mars500 crew celebrated their one full year inside the modules simulating an interplanetary spaceship. They are now flying virtually back to Earth and due to a delay in communications, introduced to make the simulation more real, some material reaches the outside world slowly. As they get nearer to Earth the communications delayed is reduced.

By September the ship will only be be only two months away from the Earth.

A Non-Toxic Fuel From the Mojave Desert


Late next year, a cargo freighter will deliver a potentially revolutionary new propulsion system to the International Space Station.

Franklin Chang-Diaz’s VASIMR engine? No, that test is still a couple of years off.

The propulsion system is called NOFBX. It’s a green fuel system developed by a little-known Mojave-based R&D company called Firestar Technologies. And it could well be one of those “game changing” technologies that NASA officials believe will make space travel a lot more affordable.

Astrobotic Wins NASA Award to Study Lunar and Martian Lava Tubes, Caves

PITTSBURGH, PA – Astrobotic PR – NASA today selected Astrobotic Technology Inc. to research breakthroughs in methods to explore lava tubes, caves and recently discovered “skylights” leading down into these features on the Moon and Mars.

Lava tubes and other types of caves can shelter astronauts and robots from harsh off-world environments, which on the Moon means micrometeorite bombardment, intense radiation and extreme temperature swings of 500 degrees from day to night. Cave-dwelling by early astronauts and robots likely will be less expensive than bringing shelter materials all the way from Earth.

Astrobotic Technology, in cooperation with Carnegie Mellon University, is preparing a robotic expedition to the Moon to be launched in the December 2013 – July 2014 time frame.

Astrobotic was one of 30 companies, universities and NASA organizations that were selected for negotiation today by the NASA Innovative Advanced Concepts (NIAC) program in the Office of Chief Technologist. The approximately $100,000 award is to cover a year-long study starting next month.

Astrobotic will be eligible for a $500,000 Phase 2 award next year to continue the work.

NASA Confident About MSL as Martian Landing Site is Chosen


During the NASA Lunar Science Forum last week, Jim Green was asked if there was any chance of the Mars Science Laboratory Curiosity being slipped another two years. NASA’s director of Planetary Science was emphatic that the probe, originally set to launch in 2009, would make its planned launch window set for Nov. 25 to Dec. 18. The car-sized rover was recently plugged into its power supply at its launch site in Florida and everything worked fine, he said.

Green and other NASA officials also announced last week that Curiosity would explore a layered mountain inside the planet’s Gale crater after it lands next August. The target crater spans 96 miles (154 kilometers) in diameter and holds a mountain rising higher from the crater floor than Mount Rainier rises above Seattle. Gale is about the combined area of Connecticut and Rhode Island. Layering in the mound suggests it is the surviving remnant of an extensive sequence of deposits. The crater is named for Australian astronomer Walter F. Gale.

Perminov Sees International Human Mars Mission in 2035 Using Nuclear Propulsion

Roscosmos Head Anatoly Perminov

ROSCOSMOS PRESS RELEASES

Mission to Mars shall be implemented under international cooperation, Roscosmos Head Anatoly Perminov stated, answering the questions from the Twitter in Echo-Moscow web.

“No country is able of performing Martian mission by its own in the nearest future. That’s an issue of propulsion. In our program, we have human flight to Mars no earlier than 2035. On the other hand, advanced nuclear propulsion can be developed in 8 years or so, provided necessary funding. With this system, you can get to Mars in about 90 days,” Roscosmos head said.

Aurora Wins SBIR, STTR Awards for Mars and CubeSat Sample Return Technology

Aurora Flight Sciences Corporation was one of the big winners when NASA announced its intention to negotiate SBIR and STTR agreements earlier this month. Four of the company’s SBIR proposals were among those chosen for negotiations along with an STTR proposal.

One of the SBIRs involves a collaboration with MIT to develop a system to capture a Martian sample return capsule launched from the surface of the Red Planet for a NASA mission. The STTR proposal is a collaboration with the Georgia Institute of Technology Center for Space Systems to develop a system to allow small small probes to return experiments from Earth orbit.

Details for both projects are shown below. I’ve also included information about three other SBIR projects that include an ISS battery recharging system, catalytic combustors for very high altitude air-breathing propulsion, and propulsion control sampling algorithms.

Mars Odyssey Sets Longevity Record

NASA MISSION UPDATE
Dec. 15, 2010

NASA’s Mars Odyssey, which launched in 2001, will break the record Wednesday for longest-serving spacecraft at the Red Planet. The probe begins its 3,340th day in Martian orbit at 8:55 p.m. EST on Wednesday to break the record set by NASA’s Mars Global Surveyor, which orbited Mars from 1997 to 2006.

Odyssey’s longevity enables continued science, including the monitoring of seasonal changes on Mars from year to year and the most detailed maps ever made of most of the planet. In 2002, the spacecraft detected hydrogen just below the surface throughout Mars’ high-latitude regions. The deduction that the hydrogen is in frozen water prompted NASA’s Phoenix Mars Lander mission, which confirmed the theory in 2008. Odyssey also carried the first experiment sent to Mars specifically to prepare for human missions, and found radiation levels around the planet from solar flares and cosmic rays are two to three times higher than around Earth.
