Pasadena, CA – Thought your Internet speeds were slow? Try being a space scientist for a day.
The vast distances involved will throttle data rates to a trickle. You’re lucky if a spacecraft can send more than a few megabits per second (Mbps).
But we might be on the cusp of a change. Just as going from dial-up to broadband revolutionized the Internet and made high-resolution photos and streaming video a given, NASA may be ready to undergo a similar “broadband” moment in coming years.

Pasadena, CA – Radar images of asteroid 2017 BQ6 were obtained on February 6th and 7th with NASA’s 70-meter (230-foot) antenna at the Goldstone Deep Space Communications Complex in California. They reveal an irregular, angular-appearing asteroid about 660 feet (200 meters) in size that rotates about once every three hours. The images have resolutions as fine as 12 feet (3.75 meters) per pixel.
“The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders,” said Lance Benner of NASA’s Jet Propulsion Laboratory in Pasadena, California, who leads the agency’s asteroid radar research program.

Pasadena, CA – NASA has selected two missions that have the potential to open new windows on one of the earliest eras in the history of our solar system – a time less than 10 million years after the birth of our sun. The missions, known as Lucy and Psyche, were chosen from five finalists and will proceed to mission formulation, with the goal of launching in 2021 and 2023, respectively.
“Lucy will visit a target-rich environment of Jupiter’s mysterious Trojan asteroids, while Psyche will study a unique metal asteroid that’s never been visited before,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate in Washington. “This is what Discovery Program missions are all about – boldly going to places we’ve never been to enable groundbreaking science.”

Washington, D.C. – In 2016, NASA drove advances in technology, science, aeronautics and space exploration that enhanced the world’s knowledge, innovation, and stewardship of Earth.
“This past year marked record-breaking progress in our exploration objectives,” said NASA Administrator Charles Bolden. “We advanced the capabilities we’ll need to travel farther into the solar system while increasing observations of our home and the universe, learning more about how to continuously live and work in space, and, of course, inspiring the next generation of leaders to take up our Journey to Mars and make their own discoveries.”
Washington, D.C. – Humanity’s great leap into the space between the stars has, in a sense, already begun. NASA’s Voyager 1 probe broke through the sun’s magnetic bubble to touch the interstellar wind. Voyager 2 isn’t far behind. New Horizons shot past Pluto on its way to encounters with more distant dwarf worlds, the rubble at the solar system’s edge.
Closer to home, we’re working on techniques to help us cross greater distances. Astronauts feast on romaine lettuce grown aboard the International Space Station, perhaps a preview of future banquets en route to Mars, or to deep space.

Greenbelt, MD – Retrieving an asteroid sample is no easy task. Doing the job blindfolded is even more challenging. That’s why scientists equipped the OSIRIS-REx spacecraft with a set of eyes to watch it all unfold.
NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) launched September 8th, 2016, and is traveling to a near-Earth asteroid known as Bennu, to harvest a sample of surface material, and return it to Earth for study. A trio of cameras will capture it all.

Pasadena, CA – What would we do if we discovered a large asteroid on course to impact Earth? While highly unlikely, that was the high-consequence scenario discussed by attendees at an October 25th NASA-FEMA tabletop exercise in El Segundo, California.
The third in a series of exercises hosted jointly by NASA and FEMA — the Federal Emergency Management Agency — the simulation was designed to strengthen the collaboration between the two agencies, which have Administration direction to lead the U.S. response.

Pasadena, CA – The number of discovered near-Earth asteroids (NEAs) now tops 15,000, with an average of 30 new discoveries added each week. This milestone marks a 50 percent increase in the number of known NEAs since 2013, when discoveries reached 10,000 in August of that year.
Surveys funded by NASA’s Near Earth Object (NEO) Observations Program (NEOs include both asteroids and comets) account for more than 95 percent of discoveries so far.
The 15,000th near-Earth asteroid is designated 2016 TB57.

Washington, D.C. – The crew of the International Space Station soon will be equipped to perform dozens of new scientific investigations with cargo launched Monday aboard NASA’s latest commercial resupply services mission from the agency’s Wallops Flight Facility in Virginia.
Orbital ATK’s Cygnus spacecraft lifted off at 7:45pm EDT from the Mid-Atlantic Regional Spaceport’s Pad 0A on the company’s upgraded Antares 230 rocket carrying more than 5,100 pounds of cargo. Cygnus is scheduled to arrive at the space station Sunday, October 23rd. Expedition 49 astronauts Takuya Onishi of the Japan Aerospace Exploration Agency and Kate Rubins of NASA will use the space station’s robotic arm to grapple Cygnus, about 6:00am.

Greenbelt, MD – Its science instruments have been powered on, and NASA’s OSIRIS-REx spacecraft continues on its journey to an asteroid. The spacecraft has passed its initial instrument check with flying colors as it speeds toward a 2018 rendezvous with the asteroid Bennu.
Last week NASA’s spacecraft designed to collect a sample of an asteroid ran the first check of its onboard instruments. Starting on September 19th, engineers controlling the Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft powered on and operated the mission’s five science instruments and one of its navigational instruments.
