NASA’s Cashflow Problem Puts Moon Trip In Doubt

Monday, August 17th, 2009

krou writes "According to the Guardian, the Augustine panel is going to declare that there is simply no money to go back to the moon, and the next-generation Ares I rocket is likely to be scrapped unless there is more funding. The $81B Constellation Program’s long-term goal of putting a human on Mars is almost certainly not going to be possible by the middle of the century. The options outlined by the panel for the future of NASA ‘are to extend the working life of the aging space shuttle fleet beyond next year’s scheduled retirement until 2015, while developing a cheaper transport to the moon; pressing ahead with Constellation as quickly as existing funding allows; or creating a new, larger rocket that would allow exploration of the solar system while bypassing the moon.’ All of this means that NASA won’t be back on the moon before the end of the next decade as hoped, ‘or even leaving lower Earth orbit for at least another two decades.’ Another result of the monetary black hole is that they don’t have the ‘$300m to expand a network of telescopes and meet the government’s target of identifying, by 2020, at least 90% of the giant space rocks that pose a threat to Earth.’"

NASA Developing Nuclear Reactor For Moon and Mars

Monday, August 17th, 2009

Al writes "NASA recently finished testing a miniature nuclear reactor that would provide power for an astronaut base on the Moon or Mars. The reactor combines a small fission system with a Stirling engine to make a ’safe, reliable, and efficient’ way to produce electricity. The system being tested at NASA’s Glenn Research Center can produce 2.3 kilowatts and could be ready for launch by 2020, NASA officials say. The reactor ought to provide much more power than solar panels but could prove controversial with the public concerned about launching a nuclear power source and placing it on the Moon or another planet."

Nearby, Recent Interplanetary Collision Inferred

Friday, August 14th, 2009

The Bad Astronomer writes about a new discovery by the Spitzer Space Telescope, which detected signs of an interplanetary smashup only 100 light-years from here, and only a few thousand years ago. There’s a NASA-produced animation of the collision between a Mercury-sized planet and a moon-sized impactor. The collision’s aftermath was detected by the presence of what are essentially glass shards in orbit around the star. Here’s NASA’s writeup.

NASA Wants To Fund Space Taxis

Friday, August 14th, 2009

NASA plans on using million in stimulus funds to seed development of a commercial passenger transportation service to space. Potential space taxi inventors have 45 days to submit their proposals. The proposals will be competitively evaluated and the winners will be announced by the end of September. It is unclear what other Commodore 64 games NASA plans on making a reality, but I hope Arkanoid makes the short list.

NASA To Text Message Interplanetary Cousins

Friday, August 14th, 2009

An anonymous reader writes "Inhabitants of the planet Gliese 581d will need a radio receiver and the ability to interpret binary code if they are to understand a series of text messages to be sent from Australia. Hello from Earth will collect the messages over the next 12 days and transmit them to the closest Earth-like planet that has the potential to harbor life. All the messages will be collected and exported as a text file and sent to NASA’s Jet Propulsion Laboratory in California, where it will be encoded into binary code, packaged and tested before transmission."

$2 Million NASA Power Beaming Challenge Heating Up

Friday, August 14th, 2009

carstene writes "Qualification rounds for the NASA Centennial Challenge Power beaming contest are underway at the Dryden Flight Research Center. The contest uses a scale model of a space elevator as a race track. Entrants must build a robot to climb a cable, suspended by helicopter, 1 km into the sky without any on board energy storage. The teams are using high power laser beams to transmit power from ground stations to photovoltaic arrays on the robots. If a team can accomplish this at 5 meters per second average speed then they could win up to 2 million dollars. One day this technology could be used to power rovers in shadowed areas of the moon or to recharge electric UAV’s in-flight or even a space elevator in the far future. A blog of the event can be found here. Full disclosure: I’m a member of the LaserMotive team that you can follow on twitter, or or via blog."

Hubble Photographs Jupiter’s New "Scar"

Friday, August 14th, 2009

BearRanger writes "Calibration of new systems in the Hubble Space Telescope (installed in May by Shuttle Atlantis astronauts) were interrupted to take pictures of the new ’scar’ near the south pole of Jupiter. The scar is believed to have been caused by the impact of an asteroid or small comet with the gas giant, which we discussed last Sunday. Hubble’s return to service will be delayed by this interruption, but NASA says that rare events such as this warrant the delay. This is only the second recorded impact of an object with Jupiter."

Electronic Armageddon, and No Electricity Either

Friday, August 14th, 2009

Smart grid technology is a hot issue on Capitol Hill, but some are raising questions about the idea. In recent days we’ve discussed the smart grid’s potential exposure to worm attacks, consumers’ unreadiness for the idea, and whether the whole concept may need a rethink. A Congressional hearing on Thursday surfaced another reason for caution: the smart grid’s vulnerability to EMP. "Electromagnetic Pulse" refers to the damage caused in electrical circuits and systems when a nuclear explosive goes off nearby. The electric grid as it’s currently constituted is vulnerable to EMP; the further down the road we go towards a smart grid, the more vulnerable it will become. "It makes a great equalizer for small nations looking to stand up to military Goliaths, argues Rep. Roscoe Bartlett (Rep.-Md.), a former research scientist and engineer who has worked in the past on projects for NASA and the military. All one needs to wreak some serious EMP damage, he charges, is a sea-worthy steamer, 0,000 to buy a scud-missile launcher, and a crude nuclear weapon. Then fling the device high into the air and detonate its warhead. Such a system might not paralyze the entire United States, he concedes. ‘But you could shut down all of New England. And if you missed by 100 miles, it’s as good as a bulls eye.’"

coondoggie writes to mention that NASA’s Green Flight Challenge is offering up to .5 million for an aircraft that can hit 200 passenger miles per gallon while maintaining 100 mph on a 200 mile flight. “The Challenge is intended to bring about the development and convergence of new technologies and innovations that can improve the community acceptance, efficiency, door-to-door speed, utility, environmental-friendliness, affordability and safety of future air vehicles, CAFÉ stated. Such technologies and innovations include, but are not limited to, bio-fueled propulsion, breakthroughs in batteries, motors, fuel-cells and ultra-capacitors that enable electric-powered flight, advanced high lift technologies for very short takeoff and landing distances, ultra-quiet propellers, enhanced structural efficiency by advances in material science and nano-technology and safety features such as vehicle parachutes and air-bags.”

Strange New Objects Seen In Saturn’s Rings

Friday, August 14th, 2009

Every 15 Earth years, Saturn has its equinox — the time during which its rotational axis is perpendicular to the rays from the sun, so that the sun is always directly “overhead” of Saturn’s equator. This is significant because Saturn’s rings orbit over the equator, so during the equinox, light from the sun hits them edge-on. This means that any objects wider than the rings, or orbiting above or below them, cast long shadows and are much easier to see. For the first time, we’re able to get detailed images of these objects, thanks to Cassini. A moonlet, perhaps 1,300 feet in diameter, has been discovered in the B-ring, and the Bad Astronomy blog points out another object that seems to be bursting through the F-ring. Quoting: “The upward-angled structure is definitely real, as witnessed by the shadow it’s casting on the ring material to the lower left. And what’s with the bright patch right where this object seems to have slammed into the rings? Did it shatter millions of icy particles, revealing their shinier interior material, making them brighter? Clearly, something awesome and amazing happened here.
