Asteroid 316201 Malala discovered by NEOWISE

NASA’s NEOWISE spacecraft discovered this new asteroid in the main belt between Mars and Jupiter. Previously called 2010 ML48, the International Astronomical Union (IAU) recently renamed this asteroid to 316201 Malala in honour of Pakistani Nobel Prize winner Malala Yousafzai. Asteroid 316201 Malala orbits the sun every five years and is composed of a very dark material that is four kilometers in diameter.

Lecture on Dawn’s mission to the asteroid belt https://secretsofspace.com/lecture-on-dawns-mission-to-the-asteroid-belt/ Fri, 06 Mar 2015 15:00:00 +0000 http://secretsofspace.com/?p=1112 Continue reading Lecture on Dawn’s mission to the asteroid belt ]]>

This is a Theodore von Kármán Lecture Series talk, held last November at NASA’s Jet Propulsion Laboratory in Pasadena, California. It addressed some of the key aspects to NASA’s “Asteroid Redirect Robotic Mission” as it looks to take human space travel to a new level by breaking out of the recent low Earth orbit missions. This talk was given by a long time veteran of the Jet Propulsion Lab, Brian Muirhead who is currently the Chief Engineer at JPL. Discussion included what is involved in planning a mission to the asteroid belt, possible target asteroids to capture, how to bring the asteroid back to orbit around the Moon for study, space craft design, propulsion, planetary defense techniques, robotic technologies required for such endeavours, and much more.

Dawn spacecraft looks for life on Ceres https://secretsofspace.com/dawn-spacecraft-looks-life-ceres/ Fri, 23 Jan 2015 15:00:00 +0000 http://secretsofspace.com/?p=1054 Continue reading Dawn spacecraft looks for life on Ceres ]]>

RT report looks at the upcoming exploration by NASA’s Dawn spacecraft which is approaching the dwarf planet Ceres (named after the Roman goddess of agriculture). Located in the asteroid belt, this 950 km wide body of rock and ice was previously categorized as an asteroid. Dawn will try to learn more about Ceres, which up till now  has been a bit of a mysterious dwarf planet, including looking for any signs of (previous microbial) life.

Asteroid 2011 MD, barely visible in this NASA image

NASA’s Spitzer Space telescope took this image of asteroid 2011 MD in February 2014. This infrared picture was taken at a wavelength of 4.5 microns over a very long time period (20 hours), which was needed to pick up the faint signature of the small asteroid (near the center of this image). Scientists have narrowed down the size of the space rock to roughly a mere 20 feet (6 meters).

Asteroid Gaspra photographed by the Galileo spacecraft

This image of the 17 km long and 10 km wide asteroid was taken by the Galileo spacecraft as it flew by the asteroid Gaspra (951 Gaspra) on October 29, 1991. Gaspra resides near the inner edge of the asteroid belt and has a 7 hour rotation period. This picture is believed to have been taken at a range of 16,000 kilometers (10,000 miles) using Galileo’s solid-state imaging camera. Galileo’s encounter with Gaspra marked the first instance of an asteroid being (so) closely examined by a spacecraft.

Near Earth asteroid Eros photographed by NEAR Shoemaker

Johns Hopkins University’s Near Earth Asteroid Rendezvous – Shoemaker (NEAR Shoemaker) robotic space probe was launched in 1996 to study the asteroid Eros. This picture is a mosaic of six pictures, stitched together and layered over a computer model of the asteroid’s shape. The NEAR Shoemaker probe was about 200 kilometers from Eros at the time of these photos. Several large craters are clearly visible. At the end of its mission in February 2001, the spacecraft landed on Eros.

Craters on the asteroid Vesta https://secretsofspace.com/craters-asteroid-vesta/ Sat, 22 Mar 2014 14:00:00 +0000 http://secretsofspace.com/?p=326 Continue reading Craters on the asteroid Vesta ]]> Vesta is one of the largest asteroids in our Solar System and has been the subject of study by JPL’s Dawn mission.

Twin impact craters on the Vesta asteroid

The surface of Vesta is pockmarked with impact craters. The two pictured above range from about 20 kilometers and 6 kilometers in diameter and are found in Vesta’s Urbinia quadrangle. This image was taken by NASA’s Dawn spacecraft, through the clear filter of its framing camera on December 18, 2011. Dawn was about 260 kilometers from the surface and in the low-altitude mapping orbit phase of its mission mission to study this asteroid Vesta and the dwarf planet Ceres.

Near-Earth Asteroid 2014 DX110 passes between Earth and Moon https://secretsofspace.com/near-earth-asteroid-2014-dx110/ https://secretsofspace.com/near-earth-asteroid-2014-dx110/#comments Thu, 06 Mar 2014 19:51:00 +0000 http://secretsofspace.com/?p=230 Continue reading Near-Earth Asteroid 2014 DX110 passes between Earth and Moon ]]> On Wednesday evening, a massive 100-foot wide Asteroid 2014 DX110 passed between Earth and the Moon, about 346,000 from Earth (0.9 lunar distance). DX110  was tracked by NASA Jet Propulsion Laboratory’s Near-Earth Object Observations Program (Spaceguard) and several other organizations. Here is a time lapse video of the asteroid from the SLOOH community observatory.

The Catalina sky survey also tracked a smaller asteroid, 2014 EC, about 20 to 30 feet wide and 500 to 600 tons in weight. 2014 RC will fly by much closer (62,000 km) to Earth around 1:21PM (PST) on March 6, 2014. JPL picked up yet another asteroid, 2014 EF, which was a bit smaller and further out than 2014 EC and also passed by Earth yesterday evening. There were some speculative reports that 2014 EF may have entered Earth’s upper atmosphere and broken up over Venezuela, landing into the Pacific Ocean, but this has not been corroborated by NASA or any other organizations.  All in all, a very busy couple of days for asteroid hunters.
