Rosetta at Mars

  • February 25, 2007

Rosetta at MarsESA’s unmanned Rosetta space probe, carrying the Philae lander bound for a 2014 rendezvous with Comet 67/P Churyumov–Gerasimenko, makes a gravity-assist flyby of planet Mars to alter its trajectory. As Rosetta will be only 160 miles from the Martian surface at its closest approach, the spacecraft is put into a safe mode for this critical part of its trip, and emerges unscathed. Its next gravity assist will come from Earth itself later in the year.

New Horizons at Jupiter

  • February 28, 2007

IoNASA’s New Horizons probe, on a one-way trip to become the first probe to swing past distant Pluto, picks up speed dramatically as it slingshots past Jupiter. New Horizons sensors are trained on the giant planet to get the first look at Jupiter since Galileo swan-dived into its crushing atmosphere. New Horizons gains nearly 9,000 miles per hour as it swings past Jupiter, which will put it at Pluto in July 2015. New Horizons’ camera catches an erupting volcano on Jupiter’s moon Io, spewing material 200 miles above the surface.

NASA rethinks Dawn cancellation

  • March 27, 2007

DawnNASA reverses a decision made earlier in the month to cancel the asteroid-hopping Dawn mission, following appeals and assurances from the mission managers. Intended to use ion propulsion to visit to of the asteroid belt’s largest bodies, Dawn’s cancellation does have the effect of sliding the mission from a 2006 launch to a 2007 launch. The budget for the mission is expanded from $373,000,000 to $446,000,000, and arrival at its first target, the large asteroid Vesta, is still scheduled for 2011.
