Every day, Earth is hit by 60 to 300 metric tons of space dust and smaller meteors. But sometimes, larger and more dangerous space rocks plummet to Earth, such as on June 30, 1908 when an estimated 40 meter-wide meteoroid exploded over the Tunguska, Siberia region in Russia, devastating 2000 sq. kilometers (770 square miles) […]

With Billions and Billions of dollars at stake and their reputation riding on the line, SpaceX came roaring back to life by dramatically executing a picture perfect Falcon 9 rocket launch this morning (Jan. 14) that successfully delivered a fleet of ten advanced Iridium NEXT voice and data relay satellites to orbit while simultaneously recovering the first stage on a ship at sea off the west coast of California.
KENNEDY SPACE CENTER, FL – Today is ‘Earth Departure Day’ for OSIRIS-Rex, NASA’s first mission to snatch “pristine materials” from the surface of a near Earth asteroid named Bennu and deliver them back to Earth in seven years on a mission to unlock mysteries on the formation of our Solar System and ourselves 4.5 Billion years ago.
The 4.5 Billion mile roundtrip ‘Journey to Bennu and Back’ begins today. All systems are GO for a spectacular dinner-time blastoff of NASAs OSIRIS-REx spacecraft from the Florida Space Coast.
Earth departure for NASA’s Origins, Spectral Interpretation, Resource Identification, Security – Regolith Explorer (OSIRIS-REx) spacecraft from Space Launch Complex 41 at Cape Canaveral Air Force Station on a United Launch Alliance Atlas V rocket is slated for shortly before sunset this evening, Thursday, September 8 at 7:05 p.m. EDT.
Excited spectators are filling local area hotels for this once in a lifetime mission to ‘Bennu and Back.’
Bennu is a small, carbon-rich asteroid – meaning it contains significant amounts of organic molecules, the stuff of which life is made.
Bennu is only about a third of mile in diameter, measuring 500 meters or 1,614 feet across and it crosses Earth’s orbit around the sun every six years.
You can watch the sure to be a spectacular launch live in person here in sunny Florida or live via a choice of webcasts.
NASA’s OSIRIS-REx launch coverage will be broadcast on NASA TV beginning at 4:30 p.m. EDT Sept. 8, as well as on a ULA webcast.

The United Launch Alliance Atlas V rocket and OSIRIS-REx spacecraft were rolled out some 1800 feet from the Vertical Integration Facility (VIF) – where the rocket is assembled- to launch pad 41 starting at about 9 a.m. yesterday morning September 7, 2018.
Watch this OSIRIS-Rex trailer from NASA Goddard illustrating the probes Earth departure launch phase:
NASAs OSIRIS-REx spacecraft is on a mission to explore asteroid Bennu and return a sample to Earth. The OSIRIS-REx launch window opens on September 8, 2016, when the spacecraft begins its two-year journey to Bennu aboard an Atlas V rocket at Cape Canaveral, Florida. After arriving at Bennu in 2018, OSIRIS-REx will spend over a year exploring the asteroid before approaching its surface to grab a sample. This pristine material, formed at the dawn of the solar system, will be returned to Earth in 2023, providing clues to Bennus origins and our own. Credit: NASA’s Goddard Space Flight Center/David Ladd
OSIRIS-REx will gather rocks and soil and bring at least a 60-gram (2.1-ounce) sample back to Earth in 2023. It has the capacity to scoop up to about 2 kg or more.
The mission will help scientists investigate how planets formed and how life began. It will also improve our understanding of asteroids that could impact Earth by measuring the Yarkovsky effect.
Bennu is an unchanged remnant from the collapse of the solar nebula and birth of our solar system some 4.5 billion years ago.
It was chosen as the target because it is little altered over time and thus ‘pristine’ in nature.
Bennu is a near-Earth asteroid and was selected for the sample return mission because it could hold clues to the origin of the solar system and host organic molecules that may have seeded life on Earth.
OSIRIS-REx will return the largest sample from space since the American and Soviet Union’s moon landing missions of the 1970s.
OSIRIS-REx is the third mission in NASA’s New Frontiers Program, following New Horizons to Pluto and Juno to Jupiter, which also launched on Atlas V rockets.
NASA’s Goddard Space Flight Center in Greenbelt, Maryland, is responsible for overall mission management.
OSIRIS-REx complements NASA’s Asteroid Initiative – including the Asteroid Redirect Mission (ARM) which is a robotic spacecraft mission aimed at capturing a surface boulder from a different near-Earth asteroid and moving it into a stable lunar orbit for eventual up close sample collection by astronauts launched in NASA’s new Orion spacecraft. Orion will launch atop NASA’s new SLS heavy lift booster concurrently under development.

An international trio of astronauts and cosmonauts representing the United States, Russia and Japan blasted off in the early morning Kazakh hours today, July 7, for a new mission of science and discovery to the International Space Station (ISS).
The three person crew of two men and one woman launched flawlessly into picture perfect skies from the Baikonur Cosmodrome in Kazakhstan at 9:36 p.m. EDT Wednesday, July 6 (7:36 a.m. Baikonur time, July 7), and in a brand new version of the Russian Soyuz capsule that has been significantly upgraded and modified.
The launch of the Soyuz MS-01 spacecraft was carried live on NASA TV starting approximately an hour before the usual on time liftoff from Baikonur. The three stage Soyuz booster generates 930,000 pounds of liftoff thrust.
The trio comprises Kate Rubins of NASA, Soyuz Commander Anatoly Ivanishin of the Russian space agency Roscosmos and Takuya Onishi of the Japan Aerospace Exploration Agency on the Expedition 48/49 mission.
They safely reached orbit at about 9:46 p.m. after the eight minute climb delivered them to the preliminary orbit of 143 x 118 mi. The Soyuz separated from the third stage and the solar arrays deployed as planned. NASA’s Kate Rubins was sitting in the left seat.
And precisely because it’s a heavily modified Soyuz, they will take the slow road to the ISS.
The crew will spend the next two days and 34 Earth orbits inside in order to fully check out and test the upgraded Soyuz spacecraft systems.
That’s in contrast to missions in recent years that took a vastly sped up 4 orbit 6 hour route to the space station.
Three carefully choreographed orbital adjustment burns will raise the orbit and propel the crew to the to ISS over next 2 days.
They expect to rendezvous and dock at the space station’s Russian Rassvet module at 12:12 a.m. EDT Saturday, July 9.
After conducting leak and safety check they expect to open the hatch to the ISS at about 2:50 a.m. Saturday, July 9.
You can watch all the hatch opening action live on NASA TV with coverage starting at 2:30 a.m.
They will spend about four months at the orbiting lab complex conducting more than 250 science investigations in fields such as biology, Earth science, human research, physical sciences, and technology development.
With the arrival of Rubins, Ivanishin and Onishi, the station is beefed up to its normal six person crew complement.
Rubins is on her rookie space mission. She holds a bachelor’s degree in molecular biology and a doctorate in cancer biology which will be a big focus of her space station research activities.
The new trio will join Expedition 48 Commander Jeff Williams of NASA and Flight Engineers Oleg Skripochka and Alexey Ovchinin of Roscosmos.
The Expedition 48 crew members will spend four months contributing to more than 250 experiments in fields such as biology, Earth science, human research, physical sciences and technology development.
“The approximately 250 research investigations and technology demonstrations – not possible on Earth – will advance scientific knowledge of Earth, space, physical, and biological sciences. Science conducted on the space station continues to yield benefits for humanity and will enable future long-duration human and robotic exploration into deep space, including the agency’s Journey to Mars,” says NASA.
Multiple unmanned cargo ships carrying tons of essential supplies and science experiments are also scheduled to arrive from Russia, the US and Japan over the next few months.
Stay tuned here for Ken’s continuing Earth and Planetary science and human spaceflight news.

Simple choices can sometimes lead to dramatic turns of events in our lives. Before turning in for the night last night, I opened the front door for one last look at the night sky. A brighter-than-normal auroral arc arched over the northern horizon. Although no geomagnetic activity had been forecast, there was something about that arc that hinted of possibility.
It was 11:30 at the time, and it would have been easy to go to bed, but I figured one quick drive north for a better look couldn’t hurt. Ten minutes later the sky exploded. The arc subdivided into individual pillars of light that stretched by degrees until they reached the zenith and beyond. Rhythmic ripples of light – much like the regular beat of waves on a beach — pulsed upward through the display. You can’t see a chill going up your spine, but if you could, this is what it would look like.
Auroras can be caused by huge eruptions of subatomic particles from the Sun’s corona called CMEs or coronal mass ejections, but they can also be sparked by holes in the solar magnetic canopy. Coronal holes show up as blank regions in photos of the Sun taken in far ultraviolet and X-ray light. Bright magnetic loops restrain the constant leakage of electrons and protons from the Sun called the solar wind. But holes allow these particles to fly away into space at high speed. Last night’s aurora traces its origin back to one of these holes.
The subatomic particles in the gusty wind come bundled with their own magnetic field with a plus or positive pole and a minus or negative pole. Recall that an ordinary bar magnet also has a “+” and “-” pole, and that like poles repel and opposite poles attract. Earth likewise has magnetic poles which anchor a large bubble of magnetism around the planet called the magnetosphere.
Field lines in the magnetosphere — those invisible lines of magnetic force around every magnet — point toward the north pole. When the field lines in the solar wind also point north, there’s little interaction between the two, almost like two magnets repelling one another. But if the cloud’s lines of magnetic force point south, they can link directly into Earth’s magnetic field like two magnets snapping together. Particles, primarily electrons, stream willy-nilly at high speed down Earth’s magnetic field lines like a zillion firefighters zipping down fire poles. They crash directly into molecules and atoms of oxygen and nitrogen around 60-100 miles overhead, which absorb the energy and then release it moments later in bursts of green and red light.
So do great forces act on the tiniest of things to produce a vibrant display of northern lights. Last night’s show began at nightfall and lasted into dawn. Good news! The latest forecast calls for another round of aurora tonight from about 7 p.m. to 1 a.m. CDT (0-6 hours UT). Only minor G1 storming (K index =5) is expected, but that was last night’s expectation, too. Like the weather, the aurora can be tricky to pin down. Instead of a G1, we got a G3 or strong storm. No one’s complaining.
So if you’re looking for that perfect last minute Mother’s Day gift, take your mom to a place with a good view of the northern sky and start looking at the end of dusk for activity. Displays often begin with a low, “quiet” arc and amp up from there.
Aurora or not, tomorrow features a big event many of us have anticipated for years — the transit of Mercury. You’ll find everything you’ll need to know in this earlier story, but to recap, Mercury will cross directly in front of the Sun during the late morning-early evening for European observers and from around sunrise (or before) through late morning-early afternoon for skywatchers in the Americas. Because the planet is tiny and the Sun deadly bright, you’ll need a small telescope capped with a safe solar filter to watch the event. Remember, never look directly at the Sun at any time.
If you’re greeted with cloudy skies or live where the transit can’t be seen, be sure to check out astronomer Gianluca Masi’s live stream of the event. He’ll hook you up starting at 11:00 UT (6 a.m. CDT) tomorrow.
The table below includes the times across the major time zones in the continental U.S. for Monday May 9:
|Time Zone||Eastern (EDT)||Central (CDT)||Mountain (MDT)||Pacific (PDT)|
|Transit start||7:12 a.m.||6:12 a.m.||5:12 a.m.||Not visible|
|Mid-transit||10:57 a.m.||9:57 a.m.||8:57 a.m.||7:57 a.m.|
|Transit end||2:42 p.m.||1:42 p.m.||12:42 p.m.||11:42 a.m.|
