NASA has stopped attempts to contact his Lunar Trailblazer probe, which has increased a failure in his cheap, high-risk science program.
The probeDesigned to map Lunar Water, launched on 26 February, with a ride cut with the second intuitive machines Robotic Lunar Lander. In the beginning it all went well. The spacecraft separated from the rocket about 48 minutes after the launch and the established communication.
However, the contact was lost the next day. It seemed that the solar panels were not properly oriented on the sun and the batteries of the probe were exhausted. The spacecraft was followed from the earth and observations indicated that it was in a slow twist when it ended in deep space.
Andrew Kleesh, Project Systems Engineer of Lunar Trailblazer at NASA’s Jet Propulsion Laboratory in South California, said: “While Lunar Trailblazer drifts far beyond the moon, our models showed that the solar panels would receive more sunlight to a point to turn the batteries of the space trovers.”
NASA gave the affected probe A few extra weeks in July To respond, but as the month ended, the efforts of NASA could also restore the spacecraft. Even if there had been sufficient power to turn on the radio, the signal would have been too weak for controllers to receive telemetry and to give commands.
The mission was intended to produce high -resolution water on the surface of the moon and to determine in what form the water is, how much is there and how it changes over time. The data would have been useful in future robot and human missions for the moon surface.
The Lunar Trailblazer was selected by NASA’s Simplex (small innovative missions for planetary exploration) competition. Simplex is about reducing costs by adopting a higher risk determination and less strict requirements for supervision and management.
Readers would be forgiven for a feeling of déjà vu. At the end of the last century, NASA adopted a “faster, better, cheaper” approach to missions, because it was confronted with considerable cuts on the budget. The strategy, which would increase the mission cadence and lower costs by accepting greater risks, resulted in some successes, in particular the Mars Sojourner Rover – but also losing, such as The Mars Polar Lander.
As NASA experiences further cutbacks, robot missions with lower costs and greater acceptance of the risk become more common. ®
