An Asteroid Is Coming to a Planet Near You

On 15 February 2013, asteroid 2012 DA14 will pass within 22,500 kilometers of the Earth. Geostationary satellites orbit 35,800 kilometers above the surface.

This asteroid is roughly the same size as the object that burst over Tunguska Siberia in 1908.

Our friends at The Planetary Society provided the funds that allowed La Sagra Observatory in southern Spain to upgrade one of their telescopes with a new camera capable tracking fast moving objects like 2012 DA14, and determining their orbit. The new instrument has found more than ten Near-Earth Objects (NEO), along with a previously unknown comet.

The key to the new discoveries involve fast read-out Charge-Coupled Devices (CCD) and revised image filtering software used with the space-junk tracking program at La Sagra.

20 Percent Budget Cut for NASA Planetary Science

Money for the Senate Launch System (SLS) has siphoned off funding for the things that NASA does best – Planetary Science Missions. Examples of these over the past three decades include:

  • Viking I and II Mars Landers looked for life in 1976
  • Galileo was launched in 1989 and plunged into Jupiter’s crushing atmosphere on September of 2003 to protect the possible ocean on the moon Europa.
  • The Ulysses Solar Polar Explorer was launched in 1990 and ceased operation in 2009
  • Mars Global Surveyor photographed Mars from 1997 through 2006.
  • MESSENGER was launched in 2004 and arrived in orbit around Mercury in March 0f 2011 after three flybys.
  • The Cassini-Huygens Mission to Saturn arrived in 2004 to Study Saturn and the moon Titan. Exploration continues.
  • Phoenix Mars Lander explored the Martian Polar Region in 2008

The money has been saved for the SLS and building rockets, the things for which NASA is worst:

  • X-33 Venture Star – 1996 to 2001 – 1.2 Billion – Canceled
  • DC-X Delta Clipper – 1991 to 1995 – Transferred to NASA – 1996 -Canceled
  • Constellation and Ares I – 2005 to 2010 – 10 Billion – Canceled
