The two rovers on the surface of Mars are not doing very well, as the dust storm continues and is showing no signs of decreasing in intensity. Rising dust blocks sunlight from reaching the two rovers, who are now operating just above the critical energy level.NASA is worried that things could get worse. These storms... |

The Red Planet is full of natural phenomena that are somewhat bizarre, considering the fact that Mars' atmosphere is less than 1 percent as dense as Earth's. But why do these strange phenomena occur, sometimes far more violent than similar ones in the much thicker atmosphere on Earth?Storms are the most en... |

The latest development of the Mars dust storm that threatened to damage the two rovers on the surface indicates it has weakened, but would not calm down, so NASA officials are forced to put the robotic probes on regular nap-time schedules to save energy.Precaution measures were necessary after the gigantic storm, co... |

A gigantic storm, covering a large portion of the Martian surface has affected the two Mars Exploration Rovers, causing them to lose power. NASA is worried that things could get worse. These storms appear when the planet is closest to the Sun, which increases the overall temperature and produces huge winds that lift... |

Landing at high enough speeds on sandy planets could sink the landing module deep in the sand layer, just like a rock diving into a pool. This is the conclusion of a new study that considered the problem of sand on other planets and how that could affect future manned missions to the Moon and Mars.Both Mars and the M... |

Astronomers succeeded in dissecting a pulsating red giant star, S Orionis, to examine the layers of dust and gas. This star has a pulse period of 410 days, during which it changes in volume, from one equal to the orbit of Mars to one equal to the orbit of Jupiter.S Orionis is a red giant star in the constellation O... |

Two old space probes just received new assignments, after they had fulfilled their original missions. Deep Impact and Stardust are the two robotic space travelers that NASA decided to reactivate and send to chase Comet Tempel 1.Deep Impact is a NASA space probe launched on January 12, 2005 that was designed to stud... |

The atmosphere on Mars is thinner than the one on Earth, with a surface pressure less than 1 percent that on Earth, but it is quite dusty. This doesn't prevent the planet from experiencing the largest dust storms in our solar system.Now, a gigantic storm is covering large areas of the surface, having the potent... |

The next robotic probe scheduled to land on Mars is the Phoenix Mars Lander, a new rover built for the purpose of touching and analyzing Martian water for the first time. Right now it is being prepared for launch at NASA's Kennedy Space Center in Florida.But before the actual launch, scientists are concerned th... |

The formation of a star is a long process in which dense parts of molecular clouds collapse into a ball of plasma, triggering the birth of the sun. Stellar evolution begins with a giant molecular cloud, also known as a stellar nursery.Dust clouds surround the young stars and thin out and dissipate as the star reache... |

Almost all small and medium-size stars will end up as white dwarfs, after nearly all the hydrogen in their cores has been fused into helium. Near the end of its nuclear burning stage, such a star goes through a red giant phase and then expels most of its outer material (creating a planetary nebula) until only the ho... |

A new research points out the fact that the smallest particles in lunar dust might be toxic, and could be a possible threat to astronauts inhaling them. These health effects have been signaled since NASA's Apollo missions. Astronaut Harrison H (Jack) Schmitt, the last man to step on to the Moon in Apollo 17, com... |
