The planned
launch of NASA's first probe bound for Pluto has been delayed another day due
to an early morning power outage at the spacecraft's Maryland-based mission control
center Wednesday.
Sitting
atop a Lockheed Martin-built Atlas 5 rocket, the New
Horizons spacecraft is now set to Jan. 19 at 1:08 p.m. EST (1808 GMT) based on an afternoon decision by mission managers, NASA officials said. The spacecraft was previously
slated to lift off today at 1:16 p.m. EST (1816 GMT) after high winds foiled
a Tuesday launch attempt.
"We've been
working on this for 17 years so I don't think a couple of days are going to
hurt us," New Horizons principal investigator Alan Stern, of the Southwest
Research Institute, told SPACE.com.
NASA's New Horizons spacecraft carries seven primary instruments
designed to study Pluto, its moon
system and other Kuiper
Belt objects with unprecedented detail.
Severe storms knocked out power to the New Horizons mission control center at the Johns Hopkins University's Applied Physics Laboratory in Laurel, Maryland, NASA officials said in a statement. While the center was on backup power, New Horizons mission managers want to ensure the site has sufficient backups before pressing forward with critical events like launch and early flight operations, they added.
"It's like
a double whammy," APL spokesperson Helen Worth said of the launch delay in a telephone interview. "All
we can do is try again tomorrow. People here are disappointed and this was totally
out of left field."
APL
officials said the outage occured at about 6:00 a.m. EST (1100 GMT) and anticipate power to be restored at their facilities by 5:00
p.m. EST (2200 GMT).
The outage
also affected APL mission operations for NASA's MESSENGER
spacecraft currently headed toward the planet Mercury, Worth added.
NASA's New
Horizons spacecraft has a wide launch window that extends until Feb. 14.
Mission managers would like to launch the spacecraft by Feb. 2, which would
allow New Horizons to take advantage of a gravity boost during Jupiter flyby
slated for early next year. If the probe launches by Jan. 28, it could reach
Pluto by 2015.
