The NASA STEREO spacecraft sees the disk of the Moon pass in front of the Sun in a view never seen before by human eyes -- in solar eclipses seen on Earth, the Moon and Sun are roughly the same size. I picked this as one of the Top Ten Astronomy Pictures of 2007.

NASA's Dawn spacecraft is on its way to study a pair of asteroids after lifting off Thursday, September 27, 2007 from the Cape Canaveral Air Force Station at 7:34 am EDT (4:34 am PDT). Mission controllers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., received telemetry on schedule at 9:44 am EDT (6:44 am PDT) indicating Dawn had achieved proper orientation in space and its massive solar array was generating power from the sun. During the next 80 days, spacecraft controllers will test and calibrate the myriad of spacecraft systems and subsystems, ensuring Dawn is ready for the long journey ahead. Dawn's 4.8-billion-kilometer (3-billion-mile) odyssey includes exploration of asteroid...

NASA's AIM spacecraft began its two-year mission April 25, 2007 after a flawless ride to Earth orbit aboard an Orbital Sciences Pegasus XL rocket. Launch took place at 1:26 PDT. Launch operations at Vandenberg Air Force Base in California ran smoothly, with no technical or weather issues causing concern. The AIM mission is the first dedicated to exploring mysterious ice clouds that dot the edge of space in Earth's polar regions. These clouds have grown brighter and more prevalent in recent years and some scientists suggest that changes in these clouds may be the result of climate change.

Taking multitasking to new heights, NASA launched the five THEMIS satellites aboard a single Delta II rocket from Cape Canaveral Air Force Station in Florida at 6:01 pm EST. Racing into space on the flaming power of three rocket stages and nine solid rocket motors, the THEMIS satellites will soon disperse around Earth to monitor auroras like the Northern Lights. NASA is undertaking the mission to investigate what causes auroras in the Earth's atmosphere to change in appearance and dissipate. Discovering why the light of auroras can fluctuate and fade will provide scientists with important details on how the planet's protective magnetosphere works and on the sun-Earth connection. The Mission...

Santa Clara University students control a NASA science satellite PharmaSat. It's a graduate program called "Intro To Satellite Operations." Not the first time SCU has served as mission control for a NASA satellite. Students upload commands and downlink science data, and some will later go to work for NASA.

science.nasa.gov June 4, 2010: Earth and space are about to come into contact in a way that's new to human history. To make preparations, authorities in Washington DC are holding a meeting: The Space Weather Enterprise Forum at the National Press Club on June 8th. As the Sun Awakens... (spaceweather poster, 200px) Many technologies of the 21st century are vulnerable to solar storms. [more] Richard Fisher, head of NASA's Heliophysics Division, explains what it's all about: "The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity. At the same time, our technological society has developed an unprecedented sensitivity to solar...

NASA has been busy planning for a new spacecraft, the Crew Exploration Vehicle (CEV), to be able to rendezvous with the ISS and then to take a crew back to the moon in conjunction with the Lunar Surface Access Module (LSAM). A Crew Launch Vehicle, named Ares I, derived from the Space Shuttle Solid Rocket Booster (SRB) will deliver the CEV to low Earth Orbit (LEO) while a larger rocket, Ares 5, will deliver ISS cargo of the LSAM to LEO. Once in LEO, the CEV and LSAM will dock and a J-2X Earth Departure Stage (EDS) will deliver the CEV/LSAM to Low Lunar Orbit (LLO) at 100 km. The EDS is discarded and CEV/LSAM temporarily decouple. The LSAM then performs the Lunar Orbit Insertion (LOI) to...

Original: spacex.com Dragon is intended to replace the space shuttle for heavy lifting purposes. The spacecraft, under development by the company SpaceX, is designed to carry seven people or a mixture of personnel and cargo, to and from low Earth orbit using Falcon 9 rockets. A Falcon 9 rocket is already assembled in Cape Canaveral, Fla. for a debut in the first half of 2010. A following flight, sometime between May and November, would launch the cargo-carrying Dragon spacecraft to resupply the International Space Station.

But NASA also does research much closer to home. In fact, NASA Earth Science satellites are taking part in the management and recovery of an ecosystem right in our backyard, the Chesapeake Bay. By studying the landscape around the Chesapeake Bay, NASA spacecraft are helping land managers figure out how to battle the harmful pollutants that have added to the destruction of the bay's once legendary productivity.

A group of astronomers from NASA, the Japan Aerospace Exploration Agency (JAXA) and other organizations had a front row seat to observe the Hayabusa spacecraft's fiery plunge into Earth's atmosphere. The team flew aboard NASA's DC-8 airborne laboratory, packed with cameras and other imaging instruments, to capture the high-speed re-entry over an unpopulated area of central Australia on June 13, 2010. The Japanese spacecraft completed its seven-year, 1.25 billion mile journey to return a sample of the asteroid Itokawa

NASA-Water on the Moon. Suddenly, the moon looks exciting again. It has lots of water, scientists said Friday — a thrilling discovery that sent a ripple of hope for a future astronaut outpost in a place that has always seemed barren and inhospitable. Experts have long suspected there was water on the moon. Confirmation came from data churned up by two NASA spacecraft that intentionally slammed into a lunar crater last month.
