Gale Crater forms a large natural repository for a lot of Martian geologic history. This ancient impact scar has a diameter of about 150 kilometers (90 miles) and lies close to where the cratered highlands drop off onto the northern lowlands in Elysium. Based on its size and state of pres...
The mission analysis consists of an evaluation of orbital perturbation, the computation of 螖V required for injection and rendezvous manoeuvres and an identification of close approach windows of the cycler with the two planets, allowing an evaluation of mission duration.Eventually, the presented ...
For my own part, I’m taking a different approach. I see my pick this week as the end credits song for our second chapter. So I wanted a little irony; something poppy and upbeat. Plus this song has been stuck in my head for like a week (I blame the XM). The Primitives’Crash....
Moon-sized Mars in the sky casting a rusty specter over the landscape. Like a mosquito you hear but forever fail to swat, the description has popped up at every subsequent opposition. Watch for it to reappear on schedule this apparition — and when friends ask what's up, patiently explain...
By the end of the third quarter 1968, the M-69 project was severely lagging behind its tight schedule. With the US getting ahead on all fronts of the space race, the Soviet government would not take no for an answer. At the peak of the spacecraft assembly, the work at NPO Lavochkin...
In the meantime, as the Mars-96 orbiter would make its closest approach to Mars within some 300 kilometers over 26 North latitude, its ADU engine would fire to slow it down by 1,020 meters per second in order to enter orbit around Mars with an inclination 106.4 degrees toward the Martian...
(Wide Angle Topographic Sensor for Operations and eNgineering) imager – located at the end of the robotic arm – to take close-up pictures of the borehole. Once the team has a better understanding of what happened, it will be able to ascertain when to schedule the next s...
The SAFE design approach is applicable to moderate power levels (≤2 MWt), and takes advantage of design simplifications that are possible in that power range. The SAFE is applicable primarily to propelling and providing energy to robotic missions, although extremely close derivatives of the SAFE ...
which met during 25 sessions from August to October of this year, interviewed experts across NASA and ESA, as well as in industry and academia, and made 44 recommendations to address potential areas of concern regarding the program’s scope and management, technical approach, schedule, and fundin...
With the president three hours behind schedule, but due to arrive momentarily, many people at one of the three inaugural balls seemed to be in good cheer as they milled about and snacked on meatballs and zucchini while posing for photos. “They tried so hard...
