[fornadablog.blogspot.com], Stephen Colbert discusses NASA's Mars rover Curiosity - The Bell Jar
NASAâs John Grunsfeld appeared on the Colbert Report on Wednesday, where he discussed NASAâs Curiosity Mars rover.
Even Comedy Centralâs Stephen Colbert is getting excited about NASAâs upcoming landing on the surface of Mars.
John Grunsfeld, a former veteran astronaut and NASAâs associate administrator for science missions, spoke with Mr. Colbert about the Curiosity roverâs landing, discussing the upcoming days that will include one of the U.S. space agencyâs most ambitious missions to date.
Speaking Wednesday, âThe Colbert Reportâ host discussed the Sunday landing with one of NASAâs top officials, saying that the risky landing was close to science-fiction.
âThatâs not science fiction â" thatâs really going to happen on Monday,â said Mr. Colbert upon seeing an animation of the seven minute landing sequence.
Speaking with Mr. Colbert, Mr. Grunsfeld explained that the spacecraft will hit the Martian atmosphere where it will begin its descent.
âAs it enters the atmosphere, it will start slowing down,â Mr. Grunsfeld explained. âIt will reach about 10 Gs of acceleration.â
Joking, Mr. Colbert said the speeds being discussed were exception, adding that he considered NASAâs ability to overcome such challenges as an example for the news industry.
âThatâs faster than NBC can tell us whatâs happening in London. Thatâs impressive,â joked Mr. Colbert.
NASAâs Curiosity is scheduled to land on the surface of Mars at 1:31 a.m. EDT on August 6. The landing is one of the most challenging faced by NASA spacecraft yet, and relies on a never-before-used âsky craneâ technique. The rover is too large to use the parachute or cushioning techniques previously employed, and so must take a new approach in order to land safely on the Martian surface.
The Mars Science Laboratory continues its final preparations for entry, descent and landing this upcoming weekend. On Wednesday, the flight team completed and confirmed a memory test on the software for the mechanical assembly that controls MSLâs descent motor. They also configured the spacecraft for its transition to entry, descent and landing approach mode, and they enabled the spacecraftâs hardware pyrotechnic devices. MSL is now under the control of the autonomous entry, descent and landing timeline flight software, says NASA.
