NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Two comets that will safely fly past Earth later this month may have more in common than their intriguingly similar orbits. They may be twins of a sort.

Comet P/2016 BA14 was discovered on January 22nd, 2016, by the University of Hawaii’s PanSTARRS telescope on Haleakala, on the island of Maui. It was initially thought to be an asteroid, but follow-up observations by a University of Maryland and Lowell Observatory team with the Discovery Channel Telescope showed a faint tail, revealing that the discovery was, in fact, a comet.

Comet 252P/LINEAR will safely fly past Earth on March 21, 2016, at a range of about 3.3 million miles (5.2 million kilometers). The following day, comet P/2016 BA14 will safely fly by our planet at a distance of about 2.2 million miles (3.5 million kilometers). (NASA/JPL-Caltech)

NASA to include 13 CubeSats with 2018 launch of unmanned Orion Spacecraft into Deep Space

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The first flight of NASA’s new rocket, the Space Launch System (SLS), will carry 13 low-cost CubeSats to test innovative ideas along with an uncrewed Orion spacecraft in 2018. Six of these CubeSat missions have contributions from NASA’s Jet Propulsion Laboratory, Pasadena, California.

These small satellite secondary payloads will carry science and technology investigations to help pave the way for future human exploration in deep space, including the Journey to Mars. SLS’ first flight, referred to as Exploration Mission-1 (EM-1), provides the rare opportunity for these small experiments to reach deep space destinations, as most launch opportunities for CubeSats are limited to low-Earth orbit.

The Lunar Flashlight, flying as secondary payload on the first flight of NASA's Space Launch System, will examine the moon's surface for ice deposits and identify locations where resources may be extracted. (NASA)

NASA reports Asteroid to flyby Earth on March 5th

 

Written by Dwayne Brown / Laurie Cantillo
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – A small asteroid that two years ago flew past Earth at a comfortable distance of about 1.3 million miles (2 million kilometers) will safely fly by our planet again in a few weeks, though this time it may be much closer.

During the upcoming March 5th flyby, asteroid 2013 TX68 could fly past Earth as far out as 9 million miles (14 million kilometers) or as close as 11,000 miles (17,000 kilometers). The variation in possible closest approach distances is due to the wide range of possible trajectories for this object, since it was tracked for only a short time after discovery.

Graphic indicates the cloud of possible locations asteroid 2013 TX68 will be in at the time of its closest approach to Earth during its safe flyby of our planet on March 5th. (NASA/JPL-Caltech)

NASA study will have 4 People living in an Isolated Habitat for 30 Days in preparation for long Space Missions

 

NASA’s Johnson Space Center

NASA - National Aeronautics and Space AdministrationHouston, TX – 4 people are living in an isolated habitat for 30 days. Why? Science!

This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration space missions, like a trip to an asteroid or even to Mars.

The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house.

The Human Exploration Research Analog (HERA), formerly known as the Deep Space Habitat, was transferred from the JSC Engineering Directorate to HRP in FY2013. This unique modular three-story habitat was designed and created through a series of university competitions and was previously used in the Desert Research and Technology Studies in the Arizona desert.

NASA’s Dawn Spacecraft photos reveal details of Dwarf Planet Ceres over 200 years since it’s discovery

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – New Year’s Day, 1801, the dawn of the 19th century, was a historic moment for astronomy, and for a space mission called Dawn more than 200 years later. That night, Giuseppe Piazzi pointed his telescope at the sky and observed a distant object that we now know as Ceres.

Today, NASA’s Dawn mission allows us to see Ceres in exquisite detail. From the images Dawn has taken over the past year, we know Ceres is a heavily cratered body with diverse features on its surface that include a tall, cone-shaped mountain and more than 130 reflective patches of material that is likely salt. But on that fateful evening in 1801, Piazzi wasn’t sure what he was seeing when he noticed a small, faint light through his telescope.

Giuseppe Piazzi used this instrument, called a Ramsden Circle, to discover Ceres on January 1, 1801. The telescope is on display at the Palermo Observatory in Sicily. (NASA/JPL-Caltech/Palermo Observatory)

NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Asteroid 2003 SD220 will safely fly past Earth on December 24th at a distance of 6.8 million miles (11 million kilometers). Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, have generated the highest-resolution images to date of this asteroid using the Deep Space Network’s 230-foot (70-meter) antenna at Goldstone, California.

The radar images were acquired between December 17th and December 22nd, when the distance to this near-Earth object (NEO) was narrowing from 7.3 million miles (12 million kilometers) to almost the flyby distance.

These images of an asteroid 3,600 feet (1,100 meters) long were taken on Dec. 17 (left) and Dec. 22 by scientists using NASA's giant Deep Space Network antenna at Goldstone, California. This asteroid will safely fly past Earth on Dec. 24, at a distance of 6.8 million miles (11 million kilometers). (NASA/JPL-Caltech/GSSR)

NASA’s Infrared Telescope Facility watches dead comet fly past Earth on Halloween night

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The large space rock that will zip past Earth this Halloween is most likely a dead comet that, fittingly, bears an eerie resemblance to a skull.

Scientists observing asteroid 2015 TB145 with NASA’s Infrared Telescope Facility (IRTF) on Mauna Kea, Hawaii, have determined that the celestial object is more than likely a dead comet that has shed its volatiles after numerous passes around the sun.

This image of asteroid 2015 TB145, a dead comet, was generated using radar data collected by the National Science Foundation's 1,000-foot (305-meter) Arecibo Observatory in Puerto Rico. The radar image was taken on Oct. 30, 2015, and the image resolution is 25 feet (7.5 meters) per pixel. (NAIC-Arecibo/NSF)
